Podcasts about solar probe plus

Vi bekantar oss med Solar Probe Plus-sonden som ska utforska solen. Hör också om Zeelandia, som vissa betraktar som en "försvunnen" kontinent. Redaktör: Marcus Rosenlund.

They say that the experience of watching a total eclipse is so profound, you're not the same afterward. If life-changing events are your thing and you're in the lower 48 states on August 21st, let us help you make the most of viewing the Great American Solar Eclipse. Learn the basics of where to be and what to bring, even on short notice. No eclipse glasses? Find out why a kitchen colander is an excellent Plan B. Also, the strange behavior of animals and private jet pilots during an eclipse. The latter is making the FAA sweat. Plus, how 1878 eclipse fever inspired Thomas Edison and astronomer Maria Mitchell, and what was at stake for them scientifically. And today, with astronauts able to view the Sun from space, what new science can we still learn by eclipse expeditions on Earth? And, NASA turns up the heat on solar studies with a probe to within a hair's breadth of the Sun.  Guests: David Baron - Author of “American Eclipse: A Nation's Epic Race to Catch the Shadow of the Moon and Win the Glory of the World.”   Andrew Fraknoi - Chair of the Astronomy Department, Foothill College. His latest book, for children: “When the Sun Goes Dark.”  Jay Pasachoff - Professor of Astronomy, Williams College, chair of the International Astronomical Union Working Group on Solar Eclipses.  Madhulika Guhathakurta - Astrophysicist, NASA Heliophysics Science Division and Program Scientist for the Solar Probe Plus mission.

Hosts: Ed Brown, Dr. Shayne Joseph, Lucas Randall 00:01:03 The difficult thing to do when growing artificial organs is building the intricate networks of tiny blood vessels that keep the tissue alive. A team at the Worcester Polytechnic Institute in Massachusetts found a simple way to do that: with spinach. 00:12:00 Set to launch in 2018, the Solar Probe Plus is a mission to study the Sun from a very close distance - about 6 million kilometres. It will become the fastest manmade object ever built. 00:21:49 A team of ecologists and microbiologists have been studying the bacteria found in the blowholes of killer whales. And while their results were somewhat worrying, they're not as conclusive as many media reports have claimed.   This episode contains traces of Elon Musk after SpaceX successfully reused a rocket.

Coronal mass ejection courtesy of NASA Solar Dynamics Observatory The sun can seem like a friendly celestial body. It is the source of summer, crops, and basically all life on Earth. But just as the sun decided when life on Earth could begin, it will also decide when life on Earth will definitely end. Dr. Michelle Thaller speaks with Dr. C. Alex Young, Associate Director for Science in the Heliophysics Division at NASA’s Goddard Space Flight Center. We’ll hear about the impressive fleet of spacecraft NASA uses to monitor the Sun, including the upcoming Solar Probe Plus, an exciting new mission to delve closer to our star than ever before. Episode Extras C. Alex Young’s office doormat at NASA Goddard! This 2015 video celebrates five years of solar observations from NASA’s Solar Dynamics Observatory: Follow along with the development of Solar Probe Plus, slated for launch in 2018. Find out about the fleet of Sun-observing spacecraft NASA uses to monitor our home star.

Hi...Stuart with the Show Notes for Series 19 Episode 48.   *A bounty of Brown Dwarfs and planets discovered deep in the Orion Nebula New technology allowing astronomers to peer deeper into the heart of the Orion Nebula than ever before, has revealed a massive population of previously unseen planets and brown dwarfs. The discovery shows that the Orion Nebula may be forming proportionally far more low-mass objects than closer and less active star formation regions. *Astronomers produce the most detailed map yet of the visible universe. Astronomers have produced the largest-ever, three-dimensional map yet of the visible universe -- showing some 1.2 million galaxies -- covering over a quarter of the sky and mapping out the structure of the universe over a volume of 650 cubic billion light-years. The new map allows scientists to make the best measurements so far of the effects of a mysterious force called dark energy on the expansion of the universe and consequently the ultimate fate of the cosmos. *Astronomers discover how the fabled man in the moon got his right eye A new study has discovered that a huge asteroid or protoplanet which crashed into the Moon 3.8 billion years ago was responsible for giving the fabled man in the moon his right eye. The massive 250 kilometre wide space rock created the Moon’s iconic Imbrium Basin as a result of the impact. This new size estimate means the Imbrium impactor was at least two times larger and 10 times more massive than previous estimates. *NASA’s mission to touch the Sun NASA’s first mission to “touch” the Sun has passed a critical development milestone keeping it on track for launch in July 2018. The Solar Probe Plus mission will send a spacecraft on a series of data-collecting runs through the Sun’s atmosphere.

Dipak Srinivasan of the Applied Physics Laboratory at Johns Hopkins University played a pivotal role in the New Horizons mission whose probe just passed by Pluto, and since he was also Andy's roommate back in their college days he was kind enough to talk with Andy and Matt about his work on the project. Launched in 2006, New Horizons traveled over three billion miles to gather the most comprehensive data about Pluto that mankind has ever seen, including stunning imagery of mountains and frozen plains, and en route it got a boost by slingshotting around Jupiter, becoming the fastest-moving probe in history. Dipak also gives the inside scoop on other projects he's been involved in, including the MESSENGER Mercury orbiter and the upcoming Solar Probe Plus mission to scrape the surface of the Sun.

The thermodynamic temperature of the Sun's atmosphere rises from ~6000K at the visible surface to millions of degrees in its outer atmosphere, the corona. This hot coronal plasma then expands supersonically to become the solar wind; this wind acceleration process is ongoing to very high altitudes (~10 solar radii) There is no sufficient thermal energy source for this heating and expansion, however remote sensing measurements of the coronal magnetic field suggest that the magnetic energy density is more than enough. Most of the proposed coronal heating/acceleration models involve the kinetic dissipation of plasma waves or turbulence, a process that is poorly understood. I will discuss some of these mechanisms, the associated puzzles, and the state of the art in measurements. The physics of astrophysical coronae has broader application and may apply to coronae above accretion disks, and disk-black hole interfaces in collisionless accretion, for example. The coming decade will be a golden age for coronal and heliospheric physics. Several dedicated NASA space missions (STEREO, SDO, IRIS) and the NSF's Advanced Technology Solar Telescope will provide high spatial resolution magnetic field and plasma observations of the transition region and corona. The ESA Solar Orbiter and NASA Solar Probe Plus missions will dive deep into the heliosphere and make low altitude (to 9.5 solar radii) in situ measurements. I will describe the Solar Probe Plus mission and its measurements in some detail.
