How Mars is losing its atmosphere on This Week @NASA – November 6, 2015

New findings by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission indicate that solar wind is currently stripping away the equivalent of about 1/4 pound of gas every second from the Martian atmosphere. MAVEN tracked a series of dramatic solar storms passing through the Martian atmosphere in March and found the loss was accelerated. This could suggest that violent solar activity in the distant past may have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life, to the cold, arid planet Mars is today. Also, 15 Years on space station, and counting!, Spacewalk for space station maintenance, NASA seeking future astronauts, Commercial Crew access tower progress and First SLS flight engine placed for testing!

Lulz... is that the same plane you use for astronaut Kelly's parabolic flights?

At what point of elevation in the earths atmosphere can the speed of the earh spin be utilized? Imagine if a satelite was hovering and earth is spinning from east to west, what elevation does the satellite need to be at to take advantage of the rotation speed? Anyone?

why do people blame N.A.S.A for every thing

Just wonder... Is this video, and what's in it, in a good agreement with Maxwell distribution? I'm not as good in astronomy as NASA guys, but what I know from my school years tell me that one doesn't need to look for complicated explanations if there are simple ones...

what do I have to study to become an astronaut
