The Van Allen Probes mission discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of space.

Join a LIVE Q&A with NASA and Applied Physics Laboratory scientists and Washington Post Reporter Brian Vastag at 1 p.m. EST on Friday Mar. 1, 2013 to learn about these historic discovery. These two nearly identical spacecraft launched in August 2012 and with only six months in operation, they may well rewrite science textbooks.

The probes study the Van Allen belts, gigantic radiation belts surrounding Earth, which can swell dramatically in response to incoming energy from the sun, engulfing satellites and spacecraft and creating potential threats to manned space flight.

James Van Allen discovered the radiation belts during the 1958 launch of the first successful U.S. satellite. Subsequent missions have observed parts of the belts, but what causes the dynamic variation in the region has remained something of a mystery.

Participants:
* David Sibeck, NASA Van Allen Probes Mission Scientist
* Shri Kanekal, NASA Van Allen Probes Deputy Mission Scientist
* Alex Young, NASA Space Weather Scientist
* Brian Vastag, Washington Post Science Reporter
* Sasha Ukhorskiy, Johns Hopkins Applied Physics Lab\n
