Podcasts about double asteroid redirection test dart

Astronomers following asteroid activity in space estimate there is a very small chance an object large enough to destroy a whole city could strike Earth in 2032. 在太空估计中，遵循小行星活动的天文学家很少有一个足够大的物体摧毁整个城市，可以在2032年撞击地球。 But space agency officials say even if such an asteroid keeps heading on a path toward Earth, the world is now much better-equipped to defend itself against such a threat. 但是航天局官员说，即使这样的小行星不断前往地球的道路，现在，世界已经准备好捍卫自己的威胁。 The American space agency NASA recently estimated there was a 3.1 percent chance that asteroid 2024 YR4 would hit Earth on December 22, 2032. That is the highest probability predicted for such a large space rock in modern times. 美国航天局NASA最近估计，小行星2024年将在2032年12月22日袭击地球有3.1％的机会。这是现代如此大的太空岩石所预测的最高概率。 Richard Moissl is head of the European Space Agency's (ESA) planetary defense office. While recognizing the risk the asteroid could present, he told the French news agency AFP people should not panic over such predictions. 理查德·莫斯尔（Richard Moissl）是欧洲航天局（ESA）行星防御办公室的负责人。 他告诉法国新闻机构法新社，人们不应对这种预测感到恐慌。 Astronomers have noted that the more data they gather, the odds of a direct asteroid hit are expected to keep rising over time. However, scientists say at a certain point the odds will likely drop down to zero. 天文学家指出，他们收集的数据越多，直接小行星命中的几率预计会随着时间的流逝而不断上升。 但是，科学家说，在某个时刻，赔率可能会下降到零。 Moissl said he thinks it is important to remember that even in the unlikely event the probability keeps rising to 100 percent, the world is "not defenseless." 莫斯尔说，他认为重要的是要记住，即使在不太可能的情况下，概率不断上升到100％，世界“没有防御”。 Here are some methods currently being considered as defensive measures to keep humanity safe in case there is a real threat. 以下是当前的一些方法，以防人类安全，以防有真正的威胁。Only one planetary defense method has been tried against an asteroid. In 2022, NASA's Double Asteroid Redirection Test (DART) sent a spacecraft into the 160-meter-wide Dimorphos asteroid. The effort successfully changed the asteroid's orbit around a larger space rock. 仅尝试使用一种行星防御方法来针对小行星。 在2022年，NASA的双小行星重定向测试（DART）将航天器发送到160米宽的双层小行星中。 这项努力成功地改变了小行星围绕更大的空间岩石的轨道。 Bruce Betts is chief scientist for the nonprofit Planetary Society. He told AFP that space agencies could hit the 2024 YR4 asteroid with several spacecrafts, observing how each one changed the path. 布鲁斯·贝茨（Bruce Betts）是非营利行星社会的首席科学家。 他告诉法新社，太空机构可以用几个航天器击中2024年小行星，观察每个人如何改变路径。 The asteroid discovered in December is estimated to be 40-90 meters wide -- about half the size of Dimorphos.据估计，这颗小行星在 12 月发现时有 40-90 米宽，大约是 Dimorphos 大小的一半。"You have to take care not to overdo it," Moissl warned. He said this is because if a spacecraft only partly destroys an asteroid, it could send smaller pieces of the space rock heading toward Earth. “你必须小心不要过度，”莫伊斯尔警告说。他说，这是因为如果航天器只部分摧毁了一颗小行星，它可能会将较小的太空岩石碎片送向地球。A separate idea would involve sending a large spacecraft to fly alongside a threatening asteroid. The spacecraft would not touch the asteroid, but would use its gravitational force to pull it away from Earth. 一个单独的想法将涉及将大型航天器与威胁性的小行星一起飞行。 航天器不会接触小行星，而是利用其引力将其从地球上拉开。 Moissl said another non-contact plan would put a spacecraft near the asteroid to eject a continuous flow of atoms to push the asteroid off course.莫斯尔说，另一个非接触计划将使小行星附近的航天器在小行星附近弹出，以驱散原子的连续流，以将小行星脱离路线。 Scientists have also considered painting one side of the asteroid white. They believe this could increase the light the object reflects to make it slowly change course. 科学家还考虑绘画小行星白色的一侧。 他们认为这可能会增加物体反射的光，以使其缓慢改变路线。One idea is to use a nuclear weapon against a threatening asteroid. In laboratory tests, researchers found that X-rays from a nuclear blast could move a rock. But this is considered more of a plan for kilometers-wide asteroids like the one that killed off the dinosaurs. And this method also carries the risk that a nuclear explosion could send additional pieces of the asteroid falling toward Earth. 一个想法是使用核武器来防止威胁性的小行星。 在实验室测试中，研究人员发现，来自核爆炸的X射线可能会移动岩石。 但这被认为是宽公里的小行星的计划，例如杀死恐龙的小行星。 而且该方法还具有核爆炸可能会使小行星落入地球的其他部分的风险。 A similar method – but one considered less dangerous – would involve shooting laser beams from a spacecraft to destroy the side of an asteroid in an effort to push it away from Earth. 一种类似的方法（但被认为危险的较小）将涉及从航天器射击激光束以摧毁小行星的一侧，以便将其远离地球。Moissl said that if all else fails, at least the world will have a good idea where a threatening asteroid would strike. Since astronomers believe most asteroids would at most threaten to destroy one city, efforts could be organized to get people out of an area before a strike. 莫斯尔说，如果其他所有问题都失败了，至少世界将在威胁性小行星袭击的地方有一个好主意。 由于天文学家认为大多数小行星最多都会威胁要摧毁一个城市，因此可以组织努力使人们在罢工之前离开该地区。 "Seven-and-a-half years is a long time to prepare," Moissl added. He also noted that even with the rising odds involving 2024 YR4, there is still about a 97 percent chance the asteroid will miss Earth. Moissl补充说：“七年半的准备时间是很长的时间。” 他还指出，即使涉及2024年的赔率上升，小行星仍有大约97％的机会错过地球。

The Universe is trying to kill us. We know an asteroid wiped out the dinosaurs, which was great for the rise of mammals, but how do we prevent a similar fate for humanity? Enter the Double Asteroid Redirection Test (DART) mission, NASA's first attempt at planetary defense by redirecting the orbit of an asteroid's moon. DART launched in November 2021, impacted Dimorphos in September 2022, and successfully changed the moonlet's orbit by 32 minutes. Since that successful test mission, the data from the impact and subsequent debris has been analyzed by countless teams worldwide. So what is next for planetary defense? Join communications specialist Beth Johnson as she chats with scientist Dawn Graninger from the Johns Hopkins University Applied Physics Laboratory about DART, follow-up mission Hera, and the future of saving the planet from near-Earth objects. (Recorded 2 November 2023.)

Dr. Tancredi is responsible for reclassifying Pluto as a "dwarf planet" and also used the Double Asteroid Redirection Test (DART) mission of NASA to study how impact ejecta evolve into a tail. He also shared how he missed discovering the "asteroid of the century" and that once he had a talk advertised using smoke signals. Check out this amazing episode!!

ProMED is one of the most useful scientific tools you've never heard of. It's a global surveillance system of infectious disease outbreaks which is available, for free, to researchers and the public alike. But ISID, the society which runs the platform, claim they have run out of money to support ProMED and will be switching to a subscription service, against the wishes of both users and staff. ProMED editor Marjorie Pollak tells Science in Action about the vital service ProMED has played in pandemic monitoring – including the very first COVID outbreaks - and ISID boss Linda MacKinnon considers what's next for the platform. From wildfires in Europe to droughts in Africa, we have covered every kind of environmental disaster across most of the globe in the space of the past few weeks. To complete the distressing bucket list of climate extremes, we're talking to sea ice expert Caroline Holmes on the concerning forecast for Antarctica. Despite these terrestrial challenges, NASA is still trying to defend Earth against nearby objects which might hit us from space. The Double Asteroid Redirection Test (DART) was launched at the asteroid Dimorphos back in in November 2021 and, a few weeks ago, the Hubble space telescope observed a swarm of boulders shed by Dimorphos post-impact. Some UK newspapers are concerned about their trajectory, but astronomer Dave Jewitt is here to calm us all down.

Desde que la nave espacial Double Asteroid Redirection Test (DART) de la NASA se estrelló intencionalmente contra la pequeña luna del asteroide Dimorphos el 26 de septiembre, alterando su órbita en 33 minutos, el equipo de investigación ha estado estudiando las implicaciones de cómo esta técnica de defensa planetaria podría usarse en el futuro, si fuese necesario en algún momento. Se ha realizado un análisis más detallado de la “erupción”, las muchas toneladas de roca asteroidal desplazadas y lanzadas al espacio por el impacto. Las observaciones de esa eyección en evolución le han dado al equipo de investigación una mejor comprensión de lo que logró la nave espacial DART en el lugar del impacto. Los miembros del equipo de DART brindaron una interpretación preliminar de sus hallazgos durante la reunión de otoño de la Unión Geofísica Estadounidense, el jueves 15 de diciembre, en Chicago. “Todo lo que podemos aprender de la misión DART es parte del trabajo global de la NASA para conocer a los asteroides y otros cuerpos pequeños en nuestro Sistema Solar”, dijo Tom Statler, científico del programa DART en la sede de la NASA en Washington, y uno de los presentadores en la sesión informativa. “Impactar al asteroide fue solo el comienzo. Ahora usamos las observaciones para estudiar de qué están hechos estos cuerpos y cómo se formaron, así como también para saber cómo defender nuestro planeta en caso de que un asteroide se dirija hacia nosotros”.

Anticipating the DART impact: Orbit estimation of Dimorphos using a simplified model by Shantanu P. Naidu et al. on Tuesday 11 October We used the times of occultations and eclipses between the components of the 65803 Didymos binary system observed in its lightcurves from 2003-2021 to estimate the orbital parameters of Dimorphos relative to Didymos. We employed a weighted least-squares approach and a modified Keplerian orbit model in order to accommodate the effects from non-gravitational forces such as Binary YORP that could cause a linear change in mean motion over time. We estimate that the period of the mutual orbit at the epoch 2022 September 26.0 TDB, the day of the DART impact, is $11.9214869 pm 0.000028$~h ($1sigma$) and that the mean motion of the orbit is changing at a rate of $(5.0pm 1.0)times 10^{-18}$~rad s$^{-2}$ $(1sigma$). The formal $3sigma$ uncertainty in orbital phase of Dimorphos during the planned Double Asteroid Redirection Test (DART) mission is $5.4^circ$. Observations from July to September 2022, a few months to days prior to the DART impact, should provide modest improvements to the orbital phase uncertainty and reduce it to about $4.2^circ$. These results, generated using a relatively simple model, are consistent with those generated using the more sophisticated model of citet{scheirich22}, which demonstrates the reliability of our method and adds confidence to these mission-critical results. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05101v1

Antariksh Matters #1: Small Launchers and Small Windows of Opportunity— Pranav R SatyanathThe small satellite launch vehicle market has a new player - Firefly Aerospace. The US-based private company on Saturday (October 1st 2022) conducted the first successful launch of its rocket Firefly Alpha. The company attempted a launch in September 2021, which failed to get to orbit. Today, Firefly is one of only four private NewSpace companies in the world which provide dedicated small-satellite launch service. The other three being Rocket Lab, Virgin Orbit and Astra (the last of the three companies is an interesting case).Firefly's Alpha launch vehicle can carry a payload of just over 1 ton to low-Earth orbit (LEO) and 750 kilograms to Sun Synchronous Orbit (SSO). This puts Alpha  in the same category as the Polar  Satellite Launch Vehicle (PSLV), which is the workhorse of the Indian Space Research Organisation (ISRO).  The Alpha launch vehicle is powered by four liquid-fuelled turbopump engines that use RP-1 (highly refined kerosene) and liquid oxygen (LOx). The second stage is powered by a single liquid-fuelled RP-1/LOx engine optimised for vacuum.The company is one of the few success stories in the highly competitive launch market, and success did not come easy. Firefly was founded as Firefly Space Systems in 2014,but the company went bankrupt and liquidated in 2017 and its assets were purchased by Ukrainian venture capitalist (also a tech entrepreneur) Max Polyakov and his company, Noosphere Ventures. Unfortunately, Polykov could only stand at a distance and watch Firefly's success as he was forced to sell his shares after Russia's invasion of Ukraine. A tough time for small launch companiesNot all companies witness success by the likes of Firefly. In December 2019, Vector Launch filed for bankruptcy before it could attempt a full orbital launch of its Vector-R rocket. The company has undergone restructuring and is preparing to begin suborbital flight tests. Another US-based company, Astra, has been attempting to launch its rocket into orbit since 2020, with very little success, leaving the company to abandon its Rocket 3.3 and move to a new design called Rocket 4 instead. Oher companies in the USIndia's own attempt to launch the Small Satellite Launch Vehicle (SSLV) failed to place its payloads in orbit after a malfunction in its sensors. The SSLV is operated by ISRO's newly- established commercial arm called NewSpace India Limited (NSIL). SSLV, unlike other launch vehicles, uses solid fuel in the first three stages. The final stage is a liquid-fuelled velocity trimming module. SSLV is India's attempt to enter the small satellite launch market, offering a launch-on-demand service to carry upto 500 kg to LEO or 300 kg to sun synchronous orbit.Several other launch companies around the world are preparing to tap into the growing small satellite market. Yet, it is unclear how many of these companies will survive in the coming years. More importantly, it is unclear whether these private entities have overestimated the market for small satellites, as a drop in demand puts at risk the sustainability of these companies.Small launch vehicles for IndiaIndian private launch companies are not far behind the world competitors. Two companies in particular, Agnikul and Skyroot, have risen to the occasion in their attempt to fulfil India's satellite launch demands. As an aspiring space power, India can not compete in the global space market by making an average of five launches a year. It requires dozens of launches (along with many many more satellites) to stay competitive on both commercial and national security grounds. India's forthcoming new space policy (long overdue and still nowhere in sight) must make it conducive for private launch providers to operate and thrive. ISRO, meanwhile, must focus its efforts on improving the reliability of its GSLV series of heavy-lift rockets and allow privateers to cater to the small satellite market needs.Siliconpolitik: India's Semiconductor Policies v2.0— Pranay KotasthaneEarlier this week, the Union Cabinet approved modifications to three of the four schemes introduced in December 2021 for developing a domestic semiconductor ecosystem. Several news websites have claimed that with the government “sweetening the deal”, investments in this sector will be more forthcoming. I agree, but not without some fundamental reservations. Here's why.Semiconductor FabsTo attract chip manufacturing companies, the original programme promised up to 50% upfront financial support for leading-edge nodes (28 nanometres and below). The promised fiscal support for trailing-edge nodes employing older technologies dropped commensurately, going down to 30% for a fab that produces chips at the 45-65 nanometre nodes. (The node size is a rough measure for the size of a building block in a chip. The smaller that number, the more building blocks that can be packed in the same area resulting in higher performance).Under the new scheme, the government promises upfront fiscal support of 50% for all node sizes. The change reflects two realities. First, trailing-edge fabs are crucial for India. The demand for older node sizes will not disappear anytime soon. Future applications such as 5G radios and electric vehicles will continue to require manufacturing at these nodes. Most current defence applications also require trailing-edge chips.Second, many countries are wooing the leading-edge node foundries with much larger incentive packages. Companies such as TSMC are being courted by all major powers, and it's unlikely they will pick India for the most-advanced nodes. India's chances are better for securing older technologies.Display FabsMost display panel manufacturers are located in East Asia — companies from China, Taiwan, South Korea, and Japan dominate this industry. The scheme was designed with the explicit aim of import substitution. The original scheme promised up to 50% upfront financial support subject to a cap of ₹12,000 crores. As part of the changes, this upper cap has been struck off.To me, this scheme didn't make sense even when it was announced. I have four reasons for the scepticism.* Even during the high peak of supply chain disruptions during COVID-19, there was no shortage of display panels, indicating that there are no constraints to increasing production, as is the case for chips. (The only shortage related to displays was for the driver chip, not the panels by themselves).* Apart from China and Taiwan, South Korea and Japan have leadership in specific segments of displays. So we aren't dependent on one vulnerable source, as in the case of chips.* Import dependence on China won't go away. Even if these fabs manufacture displays in India, the input materials will have to be imported from elsewhere. So the bottlenecks will shift but don't disappear.* The industry is moving to newer technologies apart from LCDs and AMOLEDs. Samsung is focusing on Quantum-dot displays instead of LCDs. The scheme might be able to get old-tech here, but for newer technologies, imports might continue.Thus, to spend ₹12000 crores for a product in the pursuit of a failed notion of import substitution doesn't justify the opportunity costs. Moreover, removing the upper cap after Vedanta-Foxconn got into this game raises concerns about rent-seeking — the tendency of businesses to distort policies to serve their own interests.Assembly, Test, Packaging Units, and Specialised Low-volume FabsFor assembly, test and packaging firms, & compound fabs, the promised financial support has increased substantially, from 30% to 50%. More importantly, the original scheme allowed disbursal once a facility had begun production. Under the modified scheme, the financial support will be upfront. Prepaid, not postpaid.These changes again warrant scrutiny. Is it another case of rent-seeking?At the margin, I am okay with the changes in this segment. India has a potential advantage because of the need for a large, mid-level trained workforce for this segment of the supply chain, in comparison to conventional semiconductor fabs.Semiconductor DesignSurprisingly, there were no modifications in the one area where India does have a comparative advantage - semiconductor design and design services. The capital requirement for this segment is at least two orders of magnitude lower than the first three segments. And yet, the response to the scheme for encouraging design firms seems less than lukewarm. We propose two changes in the policy for that segment in an article for Hindustan Times earlier this month:* To receive deployment-linked incentives under the current scheme, a design firm has to be registered in India with a 50% local stake. That clause could be watered down. Companies should qualify as long as the workforce is majorly Indian and the development happens here.* Reducing tariff and non-tariff barriers are also crucial for India's semiconductor design companies to increase operations in India.On both these counts, the status quo prevails.To summarise, the modifications reflect the government's seriousness in attracting investment in this sector. Through these changes, the government is acknowledging that India must start its chip manufacturing journey at the lower end and climb its way up. Getting good at this game takes a couple of decades. At the same time, a thin line separates responsive government policies from regulatory capture by businesses. All industrial policies run this risk, and we need to be vigilant.Antariksh Matters #2: Planetary Defence and National Defence— Aditya RamanathanOn September 26, NASA concluded what it called “the world's first planetary defense technology demonstration” in a spectacular collision. Ten months after it was first launched, NASA's 570 kilogram Double Asteroid Redirection Test (DART) spacecraft smashed into the asteroid Dimorphos. The collision occurred 11 million kilometres from Earth. Dimporphos is technically a 160 metre-long ‘asteroid moonlet' - called so because it orbits a larger asteroid named Didymos. While neither rock is headed towards Earth, the DART mission sought to establish the ability to deflect an asteroid from its trajectory.   The DART spacecraft was launched in November 2021 from a SpaceX Falcon 9 rocket and Johns Hopkins Advanced Propulsion Laboratory (JHUAPL) managed the mission. The apparent success of DART is likely to prompt more ‘planetary defence' missions. According to the latest decadal survey published by the US-based National Academies, NASA's annual budget for planetary defence is more than $160 million. NASA has tracked about 27,000 near Earth objects (NEOs) using this funding. Yet this is barely enough to track naturally occurring threats from space. In particular, NEOs that are between 30-140 metres in size and typically collide with the Earth once every century, can be hard to detect. One such celestial body was responsible for the 1908 Tunguska event. Ambitious Proposals, Enduring SuspicionsWhile the DART mission was a kinetic collision, such interventions may not suffice for every contingency. While no civilisation-killing NEOs are likely to be headed Earth's way anytime soon, smaller NEOs that can still result in catastrophes may be detected too late for deflection. Also, kinetic collisions may risk creating fragments large enough to survive reentry and cause damage on Earth. The most common proposal for dealing with such contingencies is using explosive nuclear devices. One scientific study from 2021 concluded that such devices were likely to be useful in destroying major NEOs headed towards Earth. While it may be prudent to seriously examine the options available, NASA's planetary defence project is not without political implications. Any spacefaring capability that can destroy through kinetic collision, or worse yet, nuclear explosives, has obvious military implications. This is especially so because, as we have argued, space warfare is still primitive in character, depending on dual-use capabilities rather than specialised weapons or platforms. While the military applications of DART-like missions are unclear and fantastical at the moment, states are not known to take chances on such matters. For reasons of both survival and prestige, America's rivals may initiate their own planetary defence programmes in the near future. Our Reading Menu[Book] A History of Near-Earth Objects Research by Erik M.

Effects of impact and target parameters on the results of a kinetic impactor: predictions for the Double Asteroid Redirection Test DART mission by Angela M. Stickle et al. on Thursday 15 September The Double Asteroid Redirection Test (DART) spacecraft will impact into the asteroid Dimorphos on September 26, 2022 as a test of the kinetic impactor technique for planetary defense. The efficiency of the deflection following a kinetic impactor can be represented using the momentum enhancement factor, Beta, which is dependent on factors such as impact geometry and the specific target material properties. Currently, very little is known about Dimorphos and its material properties that introduces uncertainty in the results of the deflection efficiency observables, including crater formation, ejecta distribution, and Beta. The DART Impact Modeling Working Group (IWG) is responsible for using impact simulations to better understand the results of the DART impact. Pre-impact simulation studies also provide considerable insight into how different properties and impact scenarios affect momentum enhancement following a kinetic impact. This insight provides a basis for predicting the effects of the DART impact and the first understanding of how to interpret results following the encounter. Following the DART impact, the knowledge gained from these studies will inform the initial simulations that will recreate the impact conditions, including providing estimates for potential material properties of Dimorphos and Beta resulting from DARTs impact. This paper summarizes, at a high level, what has been learned from the IWG simulations and experiments in preparation for the DART impact. While unknown, estimates for reasonable potential material properties of Dimorphos provide predictions for Beta of 1-5, depending on end-member cases in the strength regime. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.06659v1

This week we are excited to welcome Dr. Scott Bellamy to the WSH. Scott is the Mission Manager for NASA's Double Asteroid Redirection Test (DART) mission which successfully launched in the early morning hours from Vandenberg atop a SpaceX Falcon 9 rocket on November 24, 2021. Scott Bellamy is one of the Mission Managers in the Planetary Missions Program Office (PMPO) at Marshall Space Flight Center (MSFC), Huntsville, AL. Presently, Scott is responsible for day-to-day oversight of the Europa Clipper flagship mission, as well as the Double Asteroid Redirection Test (DART) mission. DART's mission is to conduct a real-life experiment in changing an asteroid's orbit through kinetic impact. In late September 2022, DART will intercept the moonlet (i.e., Dimorphos,) of the asteroid Didymos — a binary system — and slow Dimorphos' orbit by up to 10 minutes. DART is the first-ever mission of this type and is sponsored by NASA's Planetary Defense Coordination Office. Europa Clipper, on the other hand, will launch in October 2024 to perform a detailed exploration of Jupiter's ocean-world moon, Europa. This mission will provide priceless information on the thickness and composition of the ice shell to possibly enable a future mission to land a probe on Europa and search for microbial life. Prior to these missions, Scott was simultaneously the Mission Manager for another project that we at CosmoQuest hold near-and-dear to our hearts, the Origins Spectral Interpretation Resource Identification Security-Regolith Explorer (OSIRIS-REx) mission to obtain and return the first-ever United States asteroid sample; the NASA Evolutionary Xenon Thruster–Commercial (NEXT-C) project providing DART's primary propulsion; and the Near Earth Object Surveyor (NEO Surveyor) mission to provide the capability for detecting low-observable asteroids. Scott originally came to Marshall Space Flight Ccenter as the Air Force Liaison Office in 2008 and afterwards retired with over 25 years of service. He then served in several roles, including being a member of the very small team that shaped what later became the Space Launch System (SLS), before joining the Planetary Missions Program Office in 2013. **************************************** The Weekly Space Hangout is a production of CosmoQuest.

Instagram's head, Adam Mosseri, will testify before America's top lawmakers in a senate subcommittee hearing in early December about the platform's harmful impact on young users, CNN reports. Mosseri is the most high-profile executive from Meta, as Facebook is now called, to agree to testify since Facebook whistleblower Frances Haugen released hundreds of internal company documents, according to CNN. Apple will be switching to its own 5G modems in 2023 instead of using technology from Qualcomm, Nikkei reports. Apple's modems will be made by TSMC—the chip maker that already supplies Apple's A-series processors and M1 system-on-chip semiconductors. Apple has been working on reducing its reliance on Qualcomm for vital semiconductor components for several years. The two companies have also contested court battles. Coinbase, America's biggest crypto exchange, has acquired crypto wallet startup BRD, to get the founders on to its own wallet team, the company said on Twitter. The BRD team will help accelerate web3 adoption and BRD's founders bring deep expertise in self-custody for crypto wallets, Coinbase said in its tweet. BRD has millions of users including in India.

TomTom, a geolocation technology company, has opened a 100,000 square feet state-of-the-art facility in Pune that can accommodate up to 1000 employees, the company said in a press release. The centre is one of TomTom's largest offices worldwide and a strategic engineering hub, according to the company. Staff can decide if they need to use the office based on the type of work at hand. NASA has launched a spacecraft that will intentionally collide with a distant asteroid in the world's first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards, the US space agency said in a press release on Wednesday. The Double Asteroid Redirection Test (DART), launched on Wednesday on a SpaceX Falcon 9 rocket from a base in California. DART is part of NASA's larger planetary defence strategy. It is built and managed by the Johns Hopkins Applied Physics Laboratory. Its goal is to slightly change the asteroid's motion in a way that can be accurately measured using ground-based telescopes. It will show that a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it—a method of deflection called kinetic impact. Interview: Ankit Tomar, CTO and Sachin Agrawal, COO at Bizongo on plans to make the company an exports facilitation platform Bizongo started as a simple way for small manufacturers to find orders more efficiently. Today it has evolved into something of an ‘operating system' for manufacturers of custom-designed goods to manage many of their supply-chain needs. In today's interview, Ankit Tomar and Sachin Agrawal, two of the three co-founders at Bizongo talk about how their tech platform will eventually catalyse and facilitate exports from India.

Dipak Srinivasan (@dipaksrinivasan), the External Engagements Lead with Johns Hopkins Applied Physics Laboratory (and Andy's former college classmate and roommate) returns to talk with Andy, Jesse and Matt about tomorrow's launch of NASA's first planetary defense mission, the Double Asteroid Redirection Test (DART), which will travel to the binary asteroid system Didymos over the course of next year to crash into the moonlet asteroid Dimorphos in an attempt to change its path and learn about how to prevent a real-life reboot of Armageddon and/or Deep Impact.

In movies, asteroids careening towards Earth confront determined humans with nuclear weapons to save the world!
