This week, Imperfect Paradise brings you New Hampshire Public Radio's Outside/In. In this episode, host Nate Hegyi and producer Justine Paradis explore the new space race and how it could impact our views of the Big Dipper. What if you were to look up at the sky and see more visible satellites than stars? What if the Big Dipper and Orion were drowned out by a satellite traffic jam, criss-crossing through space? A growing number of astronomers are sounding the alarm about such a possibility, even within the next decade. Featuring Samantha Lawler, Jonathan McDowell, Aaron Boley, and Roohi Dalal, with thanks to Edward Oughton.

Maybe you've looked at the sky on a clear night and spotted the International Space Station, a tiny white dot gliding through the stars. Maybe it felt special, a rare glimpse of a human-made satellite in space. But what if you were to look up at the sky and see more visible satellites than stars? What if the Big Dipper and Orion were drowned out by a satellite traffic jam, criss-crossing through space? A growing number of astronomers are sounding the alarm about such a possibility, even within the next decade. A new space race is already well underway. Commercial satellite traffic in low Earth orbit has skyrocketed in recent years, with more satellites launched into space than ever before. The majority of these satellites are owned and operated by a single company: Starlink. Featuring Samantha Lawler, Jonathan McDowell, Aaron Boley, and Roohi Dalal, with thanks to Edward Oughton.

China y Francia lanzan satélite para explorar el universo, cooperando en busca de explosiones cósmicas. El sábado, un cohete Long March 2-C despegó llevando el satélite Space Variable Objects Monitor, conocido como SVOM, desarrollado conjuntamente por China y Francia. Este lanzamiento es un gran ejemplo de cómo dos países pueden trabajar juntos para entender mejor el universo. El satélite, que pesa 930 kilogramos, está equipado con cuatro instrumentos científicos, dos desarrollados por Francia y dos por China, y buscará destellos de rayos gamma. Estos destellos son emitidos por fenómenos cósmicos extremadamente violentos, como la explosión de estrellas masivas o la fusión de estrellas compactas. Explosiones cósmicas y cooperación internacional. El SVOM tiene la capacidad de detectar destellos de rayos gamma cuya luz ha viajado miles de millones de años luz para llegar a la Tierra. Estos destellos, generados tras la explosión de estrellas más de 20 veces más grandes que el sol, o la fusión de estrellas compactas, emiten una cantidad de energía equivalente a la de miles de millones de soles. Observar estos rayos es como "mirar hacia atrás en el tiempo", ya que su luz tarda mucho en llegar a nosotros, explicó Ore Gottlieb, astrofísico del Centro de Astrofísica del Instituto Flatiron en Nueva York. Estos rayos gamma llevan trazas de las nubes de gas y galaxias que atraviesan en su viaje, proporcionando datos valiosos para comprender la historia y evolución del universo. Los científicos esperan que SVOM pueda resolver varios misterios en el campo de los estallidos de rayos gamma, incluyendo la detección de los más distantes en el universo. Estos estallidos corresponden a los primeros eventos cósmicos, producidos solo 630 millones de años después del Big Bang, cuando el universo estaba en su infancia. "Estamos interesados en los estallidos de rayos gamma por su propia naturaleza, ya que son explosiones cósmicas extremadamente extremas que nos permiten comprender mejor la muerte de ciertas estrellas", dijo Frederic Daigne, astrofísico del Instituto de Astrofísica de París. "Estos datos permiten probar las leyes de la física con fenómenos que son imposibles de reproducir en la Tierra". Una vez analizados, los datos obtenidos por SVOM podrían ayudar a comprender mejor la composición del espacio, la dinámica de las nubes de gas y otras galaxias. El proyecto es fruto de una asociación entre las agencias espaciales francesa y china, así como otros grupos científicos y técnicos de ambas naciones. Este nivel de cooperación espacial entre Occidente y China es poco común, especialmente desde que Estados Unidos prohibió toda colaboración entre la NASA y Beijing en 2011. En 2018, China y Francia lanzaron conjuntamente el CFOSAT, un satélite oceanográfico utilizado principalmente en meteorología marina. Varios países europeos también han participado en el programa de exploración lunar Chang'e de China. Aunque SVOM no es único, sigue siendo significativo en el contexto de la colaboración espacial entre China y Occidente, dijo Jonathan McDowell, astrónomo del Centro Harvard-Smithsonian de Astrofísica en Estados Unidos. Además, el lanzamiento del SVOM no estuvo exento de incidentes. Restos del cohete Long March 2-C cayeron en una zona poblada cerca del condado de Guiding, en la provincia de Guizhou. Este incidente fue registrado en video y compartido en la red social china Sina Weibo, mostrando a personas corriendo para ponerse a salvo. Los restos del cohete contenían propulsores hipergólicos, una mezcla tóxica de tetroxido de nitrógeno y dimetilhidrazina asimétrica, conocida por su alta peligrosidad. El gas o humo marrón rojizo visible en el video podría ser indicativo de tetroxido de nitrógeno, mientras que el gas amarillo podría haber sido causado por la mezcla de hidrazina con el aire. Los restos de cohetes caen comúnmente en áreas pobladas durante los lanzamientos desde los tres sitios de lanzamiento interiores de China. Estos sitios, establecidos durante la Guerra Fría para proporcionar protección contra tensiones con Estados Unidos y la Unión Soviética, están ubicados en zonas del interior del país, lejos de la costa. Aunque las autoridades chinas suelen emitir avisos y órdenes de evacuación para las áreas en riesgo, la caída de restos sigue siendo un problema recurrente. Este lanzamiento del SVOM fue el vigésimo noveno de China en 2024, y se espera que el país realice alrededor de 100 lanzamientos este año, incluyendo aproximadamente 30 misiones comerciales.
Jonathan McDowell is an astrophysicist and astronomer for Harvard and we finally get to ask someone of his caliber all of the big space questions we've been saving up. Why are we headed back to the moon? What does failure mean? And is Shawn right about Space photos?
Dr. Jonathan McDowell is an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA. A staff member of the Chandra X-ray Center, he studies black holes, quasars and X-ray sources in galaxies, as well as developing data analysis software for the X-ray astronomy community.

The 365 Days of Astronomy, the daily podcast of the International Year of Astronomy 2009
According to satellite cataloger Jonathan McDowell, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites. This is a whole lot of missions to try and keep from colliding and all it takes is one particularly bad collision to transform the more than half-million objects from useful technologies to a shield of shrapnel that protects our universe from us by trapping us here. In our closer look today, we are going to look at early warning systems that are being developed, and how future - more highly mobile satellites, can both do good and create chaos.

Antariksh Matters: Shattering Space Record Myths— Pranav R SatyanathEarlier this week, a record was broken in the shadowy world of military space tech. At least, that's what some of the headlines make you believe. The secretive X-37B Orbital Test Vehicle (OTV) uncrewed spaceplane, operated by the US Space Force, landed at the NASA Kennedy Space Center on November 12th after spending 908 days in orbit. It broke the previous orbital record (780 days) by a large margin. The spaceplane, which is built by Boeing, has been in operation since 2010. Its mission and purpose are largely unknown, building some sort of a myth around this mini-Space Shuttle-looking vehicle.Let's take a step back. From all the open-source images available, we know that the X-37B has a single liquid-fuelled engine built by Aerojet and powered by storable propellants. This means it can stay in orbit by increasing its altitude. So, one can say that spaceplanes are not very different from regular satellites, which operate for years and decades in orbit. Now compare those years and decades to 908 days. Not much, right? Well, yes. So long as the spaceplane can maintain orbital speed, it can stay in orbit as long as its operators wish. Although we don't know much about the X-37B's true purpose, we know some meta details that give clues as to what the purpose might be. The programme that gave birth to the X-37B isn't a secret. Back in the early 1990s, people in the US government got pretty worried about the costs of operating the Space Shuttle. It was reusable for sure, but it was a slow and painstaking process to get the vehicle back to space. So, the US Congress told NASA to go and look at other alternatives. The result was the Access to Space study, which outlined faster, better, cheaper and smaller alternatives to the Suttle. After pondering their heads over what to test, NASA began to fund a handful of companies to research and develop reusable spaceplanes, including Single-Stage To Orbit (SSTO) tech, which is considered the pinnacle of rocketry.Chief among these experimental spaceplanes included Lockheed Martin's X-33 and Orbital Science's X-34 reusable launch vehicles, along with Boeing's X-37 experimental space manoeuvring vehicle. By 1999, NASA saw the funds dry up and no progress to show. The US Air Force (USAF) was ready to take up the X-34 and the X-37 programmes. The X-34 programme got cancelled, and the X-37 was transferred to the Defense Advanced Research Projects Agency (DARPA). Two years later, the X-37B was in the hands of the USAF.From what we know, we can draw out two hypotheses:* The X-37B is a highly manoeuvrable vehicle used to inspect suspicious activities and objects in space. * The X-37B is a test vehicle for the US Space Force (and Air Force) which allows them to test hypersonic re-entry, autonomous capabilities and perhaps, deployment of small payloads.A part of the second hypothesis is already confirmed. Astronomer and space watcher Jonathan McDowell reported that the X-37B launched a subsatellite named the FalconSAT-t8, an experimental payload developed by the Air Force Academy. The second hypothesis is less likely to be true, as small satellites can perform a far better (and less suspicious) job of inspecting suspicious activities and objects.Like the US, the Chinese also have a handful of spaceplane projects. It will not be surprising that these vehicles will have both civilian and military uses. India is also testing a version of its spaceplane called the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD). Spaceplanes are interesting. But we must not get carried away by spooky headlines.Comments on the Draft Telecommunications Bill, 2022— Satya Sahu and Gayathri PotiThe draft Telecommunications Bill, 2022 will do more to prohibit Digital India's growth story rather than facilitate it. We outline some of its most glaring issues:Definitional Over-breadth, Legislative Conflict and Procedural Lacunae* Explanatory Note to the Bill in para.51 reassures that provisions concerning internet shutdowns recognize citizens' rights; there is no enumeration of this safeguard in the concerned clause nor mechanisms for judicial oversight or review panels to record the legality of suspension orders à la the Telecom Suspension Rules, 2017.* The Union Government recently withdrew the Personal Data Protection Bill, 2021. In the absence of a data protection regime and an independent Data Protection Authority vested with powers to implement safeguards on the access and use of personal data by public authorities in line with the principles laid out in Puttaswamy and Shreya Singhal. , Clause 24(2)(b) contributes to the increasingly fragmented data protection framework in India, alongside the IT Act, 2000, SEBI Data Sharing Policy, 2019, Payments and Settlements Act, 2008 etc. Regulatory uncertainty and compliance costs within this framework become increasingly difficult due to the wide gamut of entities subject to the definition of "Telecommunication services" under Clause 2(2). The increased cost of compliance with implementing KYC norms and mandatory licensing regimes will result in extremely high barriers to entry for players in the OTT market. It will ensure that only market players with significant resources to meet these obligations can afford to remain in it, amplifying concerns about stifled innovation and competition in this oligopolistic sector.* Subjecting OTT platforms to DoT jurisdiction creates regulatory overlap with MeitY's powers, creating potentially conflicting laws, duplication of efforts by regulators and market players alike, ownership of implementation measures, and increasing costs of conducting business.* OTT platforms like real-time messaging services deploy E2E encryption. Currently, access to encrypted communication is governed by the 2021 Intermediary Guidelines and Digital Media Ethics Code released by MeitY. Under this, significant social media intermediaries are only expected to enable the identification of the first originator of the information. The rules deliberately refrain from mandating access to the contents of the communication (especially since the 2015 draft rules that insisted on making available the plaintext of communications was met with heavy criticism), but Clause 24 empowers the Government to gain access to the contents of the communication as well. This conflicts with the 2021 Code and further aggravates the issue of regulatory overlap. The provision implicitly requires OTT platforms to create encryption backdoors and inevitably undermines Constitutional protection for free speech afforded by encryption.* The territorial applicability of the provisions of the Bill has not been described unlike in the Telegraph Act, 1885, and the IT Act, 2000, which circumscribe their application in terms of geography and cyber attribution. The telecom and OTT sectors depend on cross-border interconnectivity and rely on internationally administered infrastructure like satellites, marine fibre-optic cable networks, etc. It is necessary to foresee and describe the territorial limits of domestic law to avoid international conflict of laws to maintain market confidence and decrease legal costs and instances of interruption in critical services.* Clause 46 (k) of the Bill dilutes TRAI's standing to requisition information from the Government and provide recommendations before awarding licenses. Deleting the non-obstante clause and provisos to S.11 (1) of the TRAI Act eliminates TRAI's role in ensuring a level playing field for TSPs and fair and non-discriminatory treatment by the Government. Vesting TRAI with the power to investigate predatory pricing exacerbates existing overlap between the mandates of TRAI and CCI, increasing possibility of regulatory arbitrage. * Clause 24(1) vests the Central Government with the power to take temporary possession of telecommunication services, networks, and infrastructure, in the occurrence of any public emergency or in the interest of public safety. Clause 24(4) makes the exercise of this power concomitant with the duration of a public emergency or occasion. The Bill, however, does not provide any procedure for Government action nor define the terms' public safety' and 'public emergency', undermining the temporary nature of this power, inviting constitutional scrutiny and low investor confidence.Insufficient Justifications for Overarching Policy * OTT platforms should be permitted to continue operating under the existing framework without any regulatory intervention until the ITU and similar foreign jurisdictions conclusively determine the regulation of such platforms. TRAI's 2020 recommendations propose no deviation from this approach, especially since there has been limited global progress concerning OTT regulation.* Compliance with KYC norms is mandated for the issuance of SIM Cards and broadband connections; extending this requirement for accessing OTT communication services is unwarranted. The rigours associated with KYC rules are reserved for tightly regulated sectors like banking, where identity verification systems combat the incidence of high-risk pernicious activities. Mandating adherence to the KYC process for creating an account on an IM/e-mail/video telephony platform is not only disproportionate but is likely to dissuade users from accessing critical services. In particular, KYC formalities will deter consumers from testing newer platforms which could result in market stagnation.* Clause 32 envisages framing regulatory sandboxes to enable innovation and technological development in the sector. However, it allows access to regulatory sandboxes only as part of the terms and conditions under its new licensing regime defeating the intent of a regulatory sandbox. Providing access to this environment only upon the award of a license raises the costs of introducing new technology in a fixed-capital-intensive sector like telecom and entrenches the market power of already dominant entities who can bear this cost. The extent and nature of the usage of new technology cannot always be preempted in the terms of a license at the time of licensing. This creates the future burden of bearing opportunity costs of not being able to leverage its own technology in new ways on the licensee, leading to avoidable legal costs and ad hoc renegotiation.The authors are students of Takshashila's GCPP (Technology & Policy) Programme.Matsyanyaaya: Splinternet Conviction?— Bharath ReddyWe often hear predictions about a splinter-net or a bifurcated Internet. What does this mean? And what are the incentives at play other than the obvious state control and censorship?To get an idea of how the Internet could split and what it means, a good example would be Runet - the Russian national segment of the Internet. Russian interventions to create an independent national Internet range from state censorship to mandating ISPs to use national Domain Name System (DNS) servers (where website names are translated to addresses). There are also forces from outside Russia incentivising the split as well. During the initial phase of the Russia-Ukraine conflict, there were appeals by Ukraine to remove Russian domains from DNS servers which would cut them off from the rest of the Internet. This request was rejected as it could destroy trust in a global internet if the DNS does not remain neutral. However, requests by Ukraine to certificate authorities that issue SSL and TLS certificates for websites have been more successful, creating barriers in the process. Lastly, the hardware sanctions and market exits following the conflict could potentially lead to a split in internet standards.As you might know, the Internet is based on communication protocols which enable different devices to speak a common language and communicate with each other. Broadly, these protocols can be classified under - content, logic and infrastructure layers. While censorship at the content layer is quite common, a fork in the lower logic and infrastructure layers could have serious ramifications. Network effects, protocol politics and geopolitics, come together here. The largest networks have incentives to refuse to be interoperable with competitors. In the current nature of the Internet, the US and its allies wield power to cut off competitors from critical chokepoints. This power has been exercised to an extent during the recent sanctions against China and Russia. The threat of such actions creates incentives for bifurcated supply chains and in this world of bifurcated supply chains there would be takers for China's vision of national internet sovereignty. In such a scenario, future network protocols such as New IP being developed by Huawei could become more widespread. The intelligence built into the protocols at the logic and infrastructure layers could enable more surveillance and control by the ISPs and the State.The concerns around the splitting of the Internet is thus a complex interplay between technology, geopolitics, and the relation between the State and the individual.The report titled “One, Two, or Two Hundred Internets” by the Center for Security Studies (CSS), ETH Zürich is an exciting read that covers this subject in detail. As the author hopes, it helps enable informed discussion and decision-making on splitting the Internet.Our Reading Menu[Opinion] Road Ahead for UPI: Free Public Infrastructure or Yet Another Payment Mechanism? by Rohan Pai and Mihir Mahajan.[Chapter] Gene Editing and the Need to Reevaluate Bioweapons by Shambhavi Naik.[Book] Cellular: An Economic and Business History of the International Mobile-Phone Industry by Daniel D.

Antariksh Matters #1: Spying on Spy Satellites— Pranav R SatyanathIn February this year, the United States launched a nondescript satellite simply designated as NROL-87. Those who keep a close of space launches know that the NROL designation stands for national security satellites operated by the National Reconnaissance Office. The satellite likely entered a 284 x 425 km Sub-synchronous orbit with an inclination of 97.25 degrees. The NROL-87, also designated as USA 326, is suspected to be a new generation of electro-optical imaging satellite. This spy satellite, one among many operated by the US, kept to itself with nothing to bother its mission. Until now.Earlier this month, Russia launched a nondescript satellite on board a Soyuz-2.1V from the Plesetsk launch site. The secret satellite, Kosmo-2558, was launched just as NROL-87 passed above the Russian launch complex. Space watchers like Jonathan McDowell quickly predicted that Kosmos-2558 would likely reach the planar orbit of NROL-87 within 80 km of the American spy satellite’s range. The orbital behaviour of the Kosmos-2558 resembles that of an ‘inspector satellite’, which, in other words, means that Russia launched a satellite to spy on another satellite.Of course, the presence of inspector satellites in space is not a new phenomenon. Classified under the category of Rendezvous and Proximity Operations (RPO), satellites have been launched to either inspect or potentially attack other satellites in the past. Not all RPO satellites have malign intentions. For example, in the 1990s, Canada proposed using inspector satellites to verify arms control agreements in outer space. More recently, however, RPOs have been viewed with suspicion. The sharp increase in the number of satellites being placed in orbit has made it all the more difficult to predict the purpose of satellites which may or may not have military utility. Since countries do not disclose details of the satellites they launch, the lack of transparency does little to decrease uncertainties. Policymakers and policy analysts have considered several possible solutions to the problem of transparency. Some scholars propose a pre-launch notification mechanism under which countries not only notify others of the launches of rockets and ballistic missiles that are set to take place but also provide details about the nature of the launch vehicle or ballistic missile.Pre-launch notification agreements concerning ballistic missiles have been signed in bilateral settings in the past. The United States and Russia signed such an agreement in 1988. India and Pakistan signed a similar agreement in 2005. No attempt has been made to craft similar agreements for space launch vehicles. One reason might be that providing pre-launch notifications might be because countries fear that adversary countries might take countermeasures against potential spy satellites. Such concerns were expressed as far back as 1958, as seen in the memorandum from the Arms Control and Disarmament Agency (ACDA) to the President of the United States.Another solution that has been proposed to avoid the risk of RPOs is to implement a keep-out zone for satellites. While such an agreement does not require a verification mechanism, countries could choose to use space situational awareness (SSA) capabilities to enforce a keep-out zone agreement. SSA capabilities have their limitations as no single national system can currently provide full coverage of Low-earth orbit (LEO) and geosynchronous Earth orbit (GEO). Establishing a global SSA network is also challenging and expensive.Although RPOs have not been a problem till date, they may become a problem in the future. Analysts have already begun to take notice of the increase in RPOs in recent years. If countries wish to mitigate the risks associated with RPOs, they must start preliminary negotiations sooner rather than later.(The author would like to thank Aaron Bateman for providing access to declassified documents related to the US space progaramme.)Antariksh Matters #2: The Indian Army’s ‘Skylight’ Exercise— Aditya RamanathanIt would be unusual for readers of this newsletter to find an entry describing an exercise conducted by the Indian Army. However, there was much about the recently concluded Exercise Skylight that was unusual, and that warranted an entry in Technopolitik. What little is known about the exercise comes from scant official information and a few news stories. The Army’s official Twitter handle described it as a satellite communication exercise. It went on to add:“100% satellite communication assets were activated to ensure operational readiness of hi-tech satellite systems and exercise various contingencies.”The tweet would indicate Exercise Skylight tested all of the Army’s orbital communications (which are scattered across multiple satellites) and that these systems were tested for ‘contingencies’. What might be these contingencies? ThePrint cited an anonymous source who indicated the Army wanted to validate its ability to use space-based communications as a redundancy during wartime:“Conflict situations demand space-based communication because we are going by the assumption that the primary means of communication — terrestrial media — gets disrupted”.Of course, the Army understands the vital advantages space-based communications provide. This is especially evident in the Himalayas along the Line of Actual Control (LaC) with China, where satellites can enable tactical communication well beyond the line-of-sight. The Russia-Ukraine war also seems to loom over Exercise Skylight. The Times of India cited an anonymous source as saying the Army was carefully following the use of cyber and electronic warfare in that conflict. In particular, the Army appears to be impressed by the resilience of the SpaceX Starlink satellite internet constellation, which Ukrainian forces have been using to coordinate operations against Russia. In the coming years, the Army is expected to look to acquire easily portable satellite phones and “satellite high speed data backbone,” which would likely require a constellation of low earth orbit (LEO) satellites link Starlink.Before it turns to LEO, the Army will be most eager to get its own communications satellite in geostationary orbit. In March, Defence Minister Rajnath Singh cleared the path for developing the GSAT-7B satellite for the Indian Army. At present, the Army shares satellites with the other services and civilian organisations. If the GSAT-7B is put into orbit by the planned date of 2025, the Army will join the Indian Navy (which already operates the GSAT-7A) and the Indian Airforce (which operates the GSAT-7C) in having its own dedicated communications satellites parked over the most suitable spot of orbital real estate.Matsyanyaaya: How can the US-India iCET Succeed?— Arjun GargeyasA couple of months ago, the United States (US) and India decided to enhance cooperation in the technology domain. President Biden and Prime Minister Modi’s meeting resulted in the Initiative on Critical and Emerging Technologies (iCET) announcement to expand the existing partnership between the two states in specific strategic technology sectors. One interesting aspect of the iCET remains the departments spearheading the initiative. Both states' National Security Councils have been responsible for driving forward outcome-oriented projects related to the iCET. The defence and national security angle behind the technology cooperation is clearly visible through this initiative. With certain technology sectors attaining a strategic status, the iCET has the ability to help the two states focus on technologies that might have a massive impact on the security and military side. These agreements, when announced can create a flutter of conversation and remain exciting on paper. But what are the actual policy implementations under the iCET which can actually translate into on ground impact for both the states? Are there areas of focus which can improve the effectiveness of the initiative itself is something to look at. A People-Centric Approach The single point of focus in the initiative should be the human capital model to achieve the desired outcomes. Technical knowledge is central to the overall development of emerging technology areas such as 5G, quantum computing and semiconductors. With human capital being the biggest strength for both India and US, the iCET will thrive if it is made individual-centric. The governments should facilitate this exchange of ideas and foster the talent pool that exists in both countries. One of the goals set by the initiative as per the Ministry of External Affairs (MEA) was to forge better linkages between government, academia and industry in specific technology areas. This would entail cross-border human capital movement being essential to achieving those goals. Scientists, engineers and other researchers in both countries who are involved in working on critical technologies can have access to research facilities in both countries under the initiative. The exchange of STEM researchers between universities across both countries and industrial leaders and technology entrepreneurs engaged in developing strategic tech can help translate lab-level research into potential applications. An important area in the people-centric approach are the students and academic researchers studying in each other’s universities. Although this is heavily skewed towards Indians in the US academic institutions, this initiative can introduce academic fellowships for scholars to work and contribute to specific emerging technology sectors. This would help in IP creation and dissemination across borders as well as cultivate a thriving set of scientists and engineers who can contribute to technology collaboration at the government level.Focus on Funding Specific Research ProjectsAs per the White House Press Release, the US-India iCET will involve the scientific government departments from both states. As per the press statement, the National Science Foundation (NSF) of the US, along with the Department of Science and Technology (DST) will drive forward the implementation of research projects under the initiative. The statement also mentioned that the US has agreed to join six of India’s Technology Innovation hubs. This is in the hope of spearheading over 25 projects across emerging domains such as artificial intelligence and data science. This sets the foundation for another area of focus for the success of the initiative. One of the main objectives of the iCET must be to secure funding (for research and product development) for outcome-driven projects that employ critical and emerging technologies. Enhancing technological cooperation between the two states and improving the efficiency of the initiative can be done when government bodies would indulge in funding crucial research projects on emerging technologies. The iCET must put its resources into funding and supporting specific research projects that can provide a solid output and outcome. The focus must be on emerging technology areas that have the potential to use said technology to create different applications and products to tackle some of the biggest challenges faced by both countries. Improving agriculture output, mitigating climate change effects and similar research can be prioritised for funding. Another aspect would be to identify areas of technology that might dominate in the near future and focus on them. Developing state-of-the-art quantum computer systems, and building telecommunication networks using 6G are just a few among the plethora of technology areas on which the iCET can spend its resources on.

How do you track a satellite? How reliable is its re-entry into the atmosphere? And how do we know what is happening in space? Dr Jonathan McDowell, astronomer at the Harvard-Smithsonian Center for Astrophysics, talks to us about orbital profiles, space debris, and just how crowded LEO (lower Earth orbit) is getting these days. We discuss re-entry into the atmosphere, how mega-constellations might challenge our previous assumptions about the atmosphere, and how X-ray telescopes are helping us explore space.

In episode 27, we blast off to outer space with famed Harvard-Smithsonian Astrophysicist Dr. Jonathan McDowell. Ioanna & I have shared a love of space since the inception of our cosmic friendship, so we are honored that Jonathan joined us for a chat on our favorite subject! Jonathan has worked for decades studying all things space, including black holes, x-rays, and lately a lot of falling space junk (ex: the falling Chinese rocket that captivated the world earlier this year). He is the go-to guy for press inquiries and information on space, leading to him creating “Jonathan's Space Report” and his appearing in thousands of media and print pieces. We're obsessed with his live tweets and he is the funniest scientist we have ever met! Jonathan tells us about his work at the Chandra X-ray Center, why a giant rocket fell uncontrolled to earth this year, what's really inside a black hole, and he shares with us his favorite non-alcoholic beverage of choice (which he sipped on during our interview), The Mango Lassi!
Jeffrey's team is at it again. This time, they (and Jonathan McDowell!) caught an unannounced (and failed) Iranian space launch attempt and have now caught what appears to be a second unannounced (and failed) Iranian space launch attempt. The failed launch detection was covered by Zachary Cohen and Oren Liebermann at CNN, who were kind enough to get the Pentagon to confirm that the first launch did, in fact, fail. We're still waiting to hear about that second one though... Jeffrey and Scott walk through Iran's textbook space launch preparations, how Jeffrey's team tracked the preparation and launch, and how one assesses that a rocket flight failed in absence of a big, obvious explosion.

It was their twentieth launch of the Electron rocket. Unfortunately for only the third time the entire payload and second stage was lost due to an anomaly. Jonathan McDowell, space launch and activities commentator is back to discuss what this means. The post Second Stage Failure : Jonathan McDowell Comments On Rocketlabs' “Anomaly” appeared first on Trekzone.

¡Llámenle a Bruce Willis!, porque se prevé que el fin de semana caiga del cielo un enorme cohete chino de 22 toneladas… no es broma: usualmente, la basura espacial se quema al sentir el rigor de la atmosfera, pero en este caso, el cohete es tan grande que no se descarta que caigan pedazos… y quien sabe dónde. “Potencialmente, no es nada bueno”, comentó a The Guardian el astrofísico de Harvard, Jonathan McDowell. ¡ALV!
Jonathan Mcdowell is an astronomer at the Harvard-Smithsonian center of astrophysics. He studies black holes, quasars and X-ray sources in galaxies and also happens to be one of the few astronomers who takes an active interest in tracking satellites and recording rocket launches.Jonathan takes us through his work at the Smithsonian and talks about different kinds of astronomers and their research. He apparently feels like Forrest Gump (but I say way smarter!) having witnessed so many incredible breakthroughs made in astronomy during the last three decades. He is an avid reader of space sci-fi and loves to show everyone the incredible night sky through a telescope. Jonathan has an interesting take on solving the space traffic management problem and shares his perspectives on the drake equation.
Nhân loại đã bắt đầu thám hiểm Sao Hỏa ngay từ thập niên 1960, nhưng cuộc chạy đua lên Hành tinh Đỏ có vẻ như đang tăng tốc: chỉ trong khoảng thời gian từ giữa tháng 7 đến đầu tháng 8/2020, đã có 3 chuyến bay lên Sao Hỏa, tranh thủ lúc hành tinh này và Trái đất nằm cùng phía với Mặt trời, tức là nằm gần nhau nhất. Trong bối cảnh Hoa Kỳ và Trung Quốc đang căng thẳng với nhau trên nhiều hồ sơ, từ Biển Đông, Hồng Kông, cho đến thương mại, gián điệp công nghiệp, một « mặt trận » khác lại vừa được mở ra trong tháng 7/2020 giữa hai cường quốc hàng đầu thế giới : Sao Hỏa Trung Quốc : Chuyến bay đầu tiên lên Sao Hỏa Ngày 23/07, thêm một sự kiện đánh dấu lịch sử của ngành không gian Trung Quốc : Lần đầu tiên nước này phóng một phi thuyền không người lái và một robot lên Sao Hỏa. Phi thuyền mang tên Thiên Vấn-1 (Tianwen-1) sẽ bay khoảng 7 tháng, tức là sang năm 2021 mới đến hành tinh này. Tham vọng của Trung Quốc rất lớn : lần đầu tiên tự mình thực hiện tất cả những gì mà Hoa Kỳ đã làm trong nhiều chuyến bay lên Sao Hỏa từ thập niên 1960 đến nay. Có nghĩa là đặt phi thuyền lên quỹ đạo của Hành tinh Đỏ, đáp xuống đây, rồi từ phi thuyền này một robot được điều khiển từ xa sẽ tiến hành các phân tích trên bề mặt Sao Hỏa. Robot nặng hơn 200 kg, được gắn 4 tấm pin Mặt trời và 6 bánh xe, theo dự kiến sẽ hoạt động trong 3 tháng trên Hành tinh Đỏ, để phân tích bề mặt, bầu khí quyển, chụp ảnh, lập bản đồ của hành tinh này và tìm dấu vết của sự sống trước đây. Về việc này, Trung Quốc đã có nhiều kinh nghiệm, vì họ đã từng đưa hai robot lên Mặt trăng, Thỏ Ngọc-1 và Thỏ Ngọc-2, vào năm 2013 và năm 2019. Theo lời chuyên gia Jonathan McDowell, nhà thiên văn học tại Trung tâm Thiên văn học Havard-Smithsonian, với hai robot Thỏ Ngọc, coi như Trung Quốc đã tập dợt trước, vì bề mặt của Mặt trăng và Sao Hỏa rất giống nhau. Có điều Sao Hỏa nằm xa hơn Trái đất rất nhiều so với Mặt trăng, chuyến du hành càng dài thì nguy cơ hỏng hóc máy móc càng cao và việc liên lạc viễn thông với Trái đất sẽ chậm hơn nhiều. Thật ra, Trung Quốc đã từng muốn phóng một phi thuyền lên Sao Hỏa vào năm 2011 trong một chuyến bay chung với Nga, nhưng ý định này đã không thành. Tên lửa đẩy của Nga đã không thể bay đến quỹ đạo trung chuyển lên Sao Hỏa, toàn bộ các thiết bị đã rơi trở lại Trái đất và một phần bị phân rã trong bầu khí quyển. Sau thất bại đó, Bắc Kinh quyết định sẽ một mình thám hiểm Hành tinh Đỏ. Trước mắt, như ghi nhận của Jonathan McDowell, nhà thiên văn học tại Trung tâm Vật lý Thiên văn Harvard - Smithsonian, Hoa Kỳ, được AFP trích dẫn ngày 23/07/2020, đây rõ ràng là một sự kiện quan trọng đối với Trung Quốc, vì lần đầu tiên họ đi xa đến như thế trong Thái Dương Hệ. Chen Lan, nhà phân tích của trang mạng GoTaikonauts.com chuyên về các chương trình không gian Trung Quốc, nhấn mạnh nếu chuyến bay Thiên Vấn-1 thành công, đây sẽ là lần đầu tiên một phi thuyền và một robot tự hành không phải là của Mỹ hoạt động trên Sao Hỏa. Cuộc chạy đua lên Sao Hỏa giữa Trung Quốc và Hoa Kỳ khiến người ta liên tưởng đến cuộc chạy đua vào không gian giữa Mỹ và Liên Xô vào thời gian chiến tranh lạnh. Nhưng thực sự Bắc Kinh nhắm mục tiêu gì khi phóng phi thuyền lên Hành tinh Đỏ ? Theo lời Carter Palmer, chuyên gia về không gian của công ty Mỹ Forecast International, được hãng tin AFP trích dẫn, mục tiêu của Trung Quốc cũng giống như nhiều cường quốc không gian khác : Nâng cao hiểu biết của nhân loại về Sao Hỏa. Mặt khác, thám hiểm không gian còn là một niềm tự hào dân tộc. Qua việc nâng cao khả năng thám hiểm không gian, Bắc Kinh cũng gia tăng ảnh hưởng chính trị và vị thế trên trường quốc tế. Trung Quốc đang đầu tư hàng tỷ đô la vào chương trình không gian của họ với hy vọng bắt kịp châu Âu, Nga và Hoa Kỳ. Thậm chí, họ còn dự trù lắp ráp một trạm không gian lớn từ đây đến năm 2022 và trong khoảng một chục năm nữa sẽ cố gắng đưa phi hành gia lên Mặt trăng. Tìm bằng chứng sự sống trên Sao Hỏa Về phần Hoa Kỳ, cường quốc không gian hàng đầu thế giới, Sao Hỏa vẫn là một mục tiêu dài hạn. Ngày 30/07/2020, cơ quan không gian NASA đã phóng lên Sao Hỏa xe tự hành tinh vi nhất của họ, một chiếc xe lớn có 6 bánh, mang tên Perseverance (Kiên trì), để cố tìm ra những bằng chứng là cách đây 3 tỷ rưỡi năm đã có đầy những vi khuẩn sống trong các con sông trên Hành tinh Đỏ, tức là ở đây đã từng có sự sống. Chuyến du hành từ Trái đất đến Sao Hỏa của Perseverance sẽ kéo dài hơn 6 tháng và nếu đáp xuống mà không bị trục trặc gì, xe tự hành này sẽ ở lại đây trong suốt nhiều năm để thu thập và đóng gói nhiều mẫu đá mà sau này sẽ được một robot khác đem về Trái đất vào năm 2031. Như vậy, Perseverance tiếp nối công việc của 4 xe tự hành, tất cả đều là của Mỹ, đã từng đáp xuống Sao Hỏa và đã giúp cho chúng ta hiểu được Hành tinh Đỏ trước đây không phải là một hành tinh khô cằn và lạnh giá như hiện nay, mà trên đây đã từng có nước, có các hợp chất hữu cơ và một bầu không khí thuận lợi cho sự sống. Chỉ có điều, theo các nhà khoa học, sự sống trên Sao Hỏa đã không có đủ thời gian phát triển thành những dạng phức tạp hơn trước khi hành tinh này trở nên khô cằn. Trong số 4 xe tự hành mà Hoa Kỳ đã phóng lên Sao Hỏa (Pathfinder, Spirit, Opportunity và Curiosity), hiện Curiosity vẫn còn hoạt động. Mặc dù đang có dịch Covid-19, cơ quan NASA đã vẫn cố giữ nguyên lịch trình phóng Perseverance lên Sao Hỏa, một chuyến bay tốn kém đến 2,7 tỷ đô la. Cứ khoảng 26 tháng, Trái đất và Sao Hỏa lại nằm cùng một phía với Mặt trời, khoảng thời gian lý tưởng để thực hiện chuyến bay lên Hành tinh Đỏ, một cơ hội không thể bỏ lỡ. Nặng gần 1 tấn, Perseverance được gắn 19 camera, hai micro và một cánh tay robot dài 2 mét, mang theo những công cụ như máy chiếu tia laser và tia X. Trên xe tự hành này còn có một trực thăng tí hon nặng 1,8 kg, mang tên Ingenuity. Nếu thành công, Ingenuity sẽ là trực thăng đầu tiên bay trên một hành tinh khác. Theo dự kiến, Perseverance sẽ đáp xuống Sao Hỏa ngày 18/02/2021. Tham vọng không gian của Các Tiểu Vương Quốc Ả Rập Thống Nhất Nhưng không chỉ có các cường quốc không gian như Mỹ, Nga, Trung Quốc hay Liên Hiệp Châu Âu, mà nhiều nước nhỏ nay cũng có tham vọng chinh phục Hành Tinh Đỏ. Al-Amal (Hy Vọng), đó là tên phi thuyền đầu tiên của một nước Ả Rập bay lên Sao Hỏa. Phi thuyền không có người lái của Các Tiểu Vương Quốc Ả Rập Thống Nhất đã cất cánh ngày 20/07/2020 từ trung tâm không gian Tanegashima (miền tây nam Nhật Bản), sau hai lần bị đình hoãn vì lý do thời tiết xấu. Nhiệm vụ của Al-Amal Phi thuyền Al-Amal, nặng 1.350 kg, sẽ bay trong 7 tháng, vượt qua đoạn đường dài 493 triệu km để đến Sao Hỏa vào tháng 2/2021, vừa kịp lúc để đánh kỷ niệm 50 năm ngày thống nhất 7 tiểu vương quốc Ả Rập. Sau đó, Al-Amal sẽ ở trên quỹ đạo trong suốt một năm Sao Hỏa, tức là 687 ngày. Theo lời bà Sarah al-Amiri, bộ trưởng Các công nghệ tiên tiến của Các Tiểu Vương Quốc Ả Rập Thống Nhất, nhiệm vụ của Al-Amal là giúp các nhà khoa học nắm tường tận những thay đổi khí hậu của Sao Hỏa trong cả một năm. Hiểu được các bầu khí quyển của các hành tinh khác sẽ giúp các nhà khoa học hiểu rõ hơn về khí hậu Trái đất. Trả lời phỏng vấn RFI Pháp ngữ ngày 20/07/2020, chuyên gia Pháp về các vấn đề địa chính trị không gian Isabelle Sourbès Verger nhấn mạnh đến sự hợp tác quốc tế trong chương trình Sao Hỏa của Các Tiểu Vương Quốc Ả Rập Thống Nhất : « Cần phải nói rõ rằng phi thuyền được một tên lửa Nhật Bản phóng lên từ Nhật Bản. Khác với các cường quốc không gian như Trung Quốc, cũng phóng phi thuyền lên Sao Hỏa trong cùng thời gian, Các Tiểu Vương Quốc Ả Rập Thống Nhất dựa vào hợp tác quốc tế để giúp họ thực hiện chương trình này. Trong khi đó chương trình Sao Hỏa của Trung Quốc hoàn toàn tự lập, họ sử dụng tên lửa riêng và tự chế tạo phi thuyền bằng những phương tiện của họ. Nhưng họ trình bày chuyến bay này như là một sự đóng góp của khối Ả Rập vào khoa học không gian, trong sự trở lại sân khấu quốc tế, ngành khoa học các nước Ả Rập đã chọn con đường khám phá thế giới của ngày mai. Chính Trung Tâm Không Gian Các Tiểu Vương Quốc Ả Rập Thống Nhất đã phát triển một phần các dụng cụ trên phi thuyền dưới sự chỉ đạo của Mỹ. Mặc dù chịu nhiều áp lực, các kỹ sư của nước này đã hoàn thành tốt nhiệm vụ trong một thời gian rất ngắn để cho phi thuyền bay đến quỹ đạo Sao Hỏa kịp với thời điểm kỷ niệm 50 năm thống nhất các tiểu vương quốc Ả Rập. Họ không được phép phạm sai lầm vì nếu bỏ lỡ cơ hội trong khoảng thời gian mà Sao Hỏa nằm gần Trái đất, thì sẽ phải đợi thêm 2 năm rưỡi nữa. Như vậy chúng ta giống như đang trở lại thời kỳ đầu của công cuộc chinh phục không gian, với sự trợ giúp chủ yếu là của Mỹ và đôi khi là của Liên Xô đối với khối Cộng sản Đông Âu, các nước thứ ba đã có thể tham gia thám hiểm không gian, tuy chưa tự lập về khả năng phóng phi thuyền." Việc Các Tiểu Vương Quốc Ả Rập Thống Nhất phóng phi thuyền lên Sao Hỏa có phải là một kiểu « trưởng giả học làm sang » ? Không hẳn như thế, vì cũng theo lời chuyên gia Isabelle Sourbès Verger, đây hoàn toàn không phải là một sự phung phí tiền của : « Đúng hơn đây là những chuyến bay nhằm mục đích nghiên cứu khoa học cơ bản, để tìm hiểu trước đây đã có sự sống trên Sao Hỏa hay không, khí hậu trên hành tinh này ra sao, bầu khí quyển Sao Hỏa phản ứng lại với gió Mặt trời như thế nào. Những chuyến bay này tuy tốn kém, nhưng chi phí không phải là lớn quá mức, hơn nữa lại được trải dài nhiều năm, không phải một một sự phung phí. Chúng ta có thể nghi ngờ về tính khả thi của việc xây dựng một căn cứ trên Mặt trăng, nhưng còn các chuyến bay lên Sao Hỏa đã có từ thập niên 1970, và đó những chương trình nghiên cứu khoa học cơ bản để tìm hiểu thêm về không gian, kể cả về lịch sử của chính hành tinh của chúng ta. Chuyến bay lên Sao Hỏa cũng là dịp khơi lại lòng tự hào dân tộc và biết đâu qua đó có thể thu hút thế hệ trẻ đến với nghiên cứu không gian. Tương tự như các chuyến bay của Appollo ở Mỹ trước đây đã lôi cuốn công chúng trở lại với khoa học kỹ thuật, và nhiều người đã chọn đường nghiên cứu khoa học, không nhất thiết chỉ trong ngành không gian. » Thật ra tuy nhỏ, nhưng Các Tiểu Vương Quốc Ả Rập Thống Nhất là một quốc gia dầu hỏa giàu có của vùng Vịnh và hiện đã có mặt trong không gian với 9 vệ tinh nhân tạo đang hoạt động trên quỹ đạo và cộng thêm 8 vệ tinh nhân tạo dự trù sẽ được phóng. Vào tháng 09/2019, Hazza al-Mansouri đã là phi hành gia đầu tiên của Các Tiểu Vương Quốc Ả Rập Thống Nhất bay lên không gian trên phi thuyền Soyouz và cũng là công dân đầu tiên của khối Ả Rập làm việc trên Trạm Không gian Quốc tế (ISS). Tham vọng của quốc gia vùng Vịnh này không dừng ở việc phóng một phi thuyền không người lái lên Sao Hỏa, mà họ còn dự tính đưa người lên sống trên hành tinh này từ đây đến năm 2117. Trước mắt, Các Tiểu Vương Quốc Ả Rập Thống Nhất sẽ xây dựng một « thành phố khoa học » tại vùng sa mạc gần thủ đô Dubai, để mô phỏng các điều kiện sống trên Sao Hỏa, từ đó phát triển các công nghệ cần thiết để con người lên định cư trên hành tinh này. Chưa hết, Các Tiểu Vương Quốc Ả Rập Thống Nhất còn đang chuẩn bị các dự án khai thác quặng mỏ và du lịch không gian. Họ đã ký một hiệp định với Virgin Galactic, công ty du lịch không gian của nhà tỷ phú người Anh Richard Branson.
Jonathan McDowell joins Tommy to talk about SpaceX Launch, going to the moon and Mars.
A large, out-of-control piece of space debris crashed into the Atlantic Ocean last week, passing over much of the United States. China launched the the Long March 5B rocket on May 5 from the Wenchang launch site in order to deploy a test model of its upcoming crew capsule. After a week in orbit, the nearly 18-metric-ton core stage re-entered the atmosphere and crashed into the Atlantic Ocean, becoming the largest piece of uncontrolled space debris to re-enter the atmosphere since 1991, as Harvard-Smithsonian Center for Astrophysics astronomer Jonathan McDowell noted on Twitter. After the launch, the rocket began a week-long orbit. The U.S. military soon started tracking the rocket’s core stage. After a trajectory that took it over heavily populated areas such as New York and Los Angeles, the rocket hit the ocean off the coast of West Africa. Uncontrolled reentries and eventual crash sites are difficult to model, since scientists don’t fully understand the complex dynamics of the upper atmosphere, Holger Krag, head of ESA’s Space Debris Office, said in a 2018 statement. Such debris can travel vast distances in short stretches of time. The 176-foot Long March 5B rocket is designed to bring large payloads, like components of China’s upcoming space station, into orbit. This mission deployed a prototype crew capsule that would be used to bring astronauts into orbit, as well as an experimental cargo return capsule, which malfunctioned as it returned into the atmosphere, reports Spaceflight Now. This all might remind you of the 2018 uncontrolled reentry of the Chinese satellite Tiangong-1, a relatively small piece of space debris that crashed into the Pacific Ocean. The Tiangong-2 rocket reentered the atmosphere in the South Pacific as part of a controlled deorbiting last year. But the Long March 5B core stage stands out in its size. While most of the rocket would have burned up in the atmosphere, some of the denser parts could potentially survive the descent and cause localized damage on the ground, McDowell told CNN. The largest piece of space junk to re-enter Earth’s atmosphere was the Skylab space station in 1979; the larger Mir space station returned to the Earth as part of a controlled reentry in 2001. Earth is really big and mostly water, so the odds of death-by-space-debris are exceedingly slim. Still, we’re launching more satellites all the time, so it’s something that space agencies are increasingly having to consider. Freak accidents do happen, though: In 1997, a woman in Oklahoma was struck (but nt injured) by a piece of metal from a disintegrating rocket.

The United States Space Force is now officially a thing, complete with a commander and plans to put about 16,000 members of the military to work defending U.S. interests in space. But what exactly does it mean for the U.S. military to “deter aggression” in space? How could a war in space happen? And what are American interests in space, anyway?This episode, we’re going to answer those questions as best we can with the help of four experts on space weapons and policy and strategy: Jeffrey Lewis, professor at the Middlebury Institute of International Studies at Monterey, Calif.; Jonathan McDowell, astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.; Bleddyn Bowen, lecturer in International Relations at the University of Leicester, in the UK; and Brian Weeden, director of Program Planning at the Secure World Foundation.
