You may think space is empty, but there is a lot there that we can’t see. What are space weather and radiation belts?
How do you observe the radiation belts?
A new radiation belt was discovered several years ago. Tell us about that discovery.
Can you tell us about the final mission that the Van Allen probes are going on?
How do radiation belts affect space travel, astronauts and the space station?

"description": "NASA’s probe to understand a mysterious region around Earth is coming to an end. After a six and a half year long journey, the Van Allen Probes are going on one last mission. THIS WEEK NASA will move its twin Van Allen Probe satellites into a lower orbit as they begins their swan song — their last year to explore the hazardous radiation belts that surround Earth. In addition to providing non-stop observations of this little-explored region, it will act as a real-time experiment of how elements in the atmosphere can cause instruments to degrade in space.
The Van Allen Probes launched in 2012 to explore the twin radiation belts around Earth; their mission had been expected to end in 2018. Unexpectedly resistant to the high-energy radiation coursing through the region, the spacecraft were hardy enough that — with some savvy fuel conservation — the mission could be extended another year. By studying the doughnut-shaped rings of radiation and how well spacecraft can survive there, NASA can better understand how radiation affects astronauts and technology sent into space. Join NASA scientists from 6:00 a.m. to 12:00 p.m. EDT on Tuesday, February 12, to learn about the Van Allen Probes’ final operation.

"description": "On March 17, 2015, an interplanetary shock – a shockwave created by the driving force of a coronal mass ejection, or CME, from the sun – struck the outermost radiation belt, triggering the greatest geomagnetic storm of the preceding decade. And NASA's Van Allen Probes were there to watch it. One of the most common forms of space weather, a geomagnetic storm describes any event in which Earth’s magnetic environment – called the magnetosphere – is suddenly, temporarily disturbed. Such an event can also lead to change in the radiation belts surrounding Earth, but researchers have seldom been able to observe what happens within the first few minutes immediately following a shock. But on the day of the March 2015 geomagnetic storm, one of the Van Allen Probes was located at just the right spot within the radiation belts, providing unprecedentedly high-resolution data from a rarely witnessed phenomenon. A paper on these observations was published in the Journal of Geophysical Research on Aug. 15, 2016. || ",

"title": "Earth's Song",
"description": "Suspended in the dark cosmos, Earth sings to itself in a high-pitched chorus of chirps and beeps. This song is a product of very low frequency radio waves generated by lightning strikes or excited electrons zipping through the Van Allen Belts, two vast swaths of radiation surrounding Earth. While ham radio operators have long detected this eerie planetary sound using inexpensive receivers, the recent recording by specially designed antennas on NASA's twin Van Allen Probes is one of the clearest examples ever captured. But could Earth's chorus be a siren song? The probes are now on a quest to find out whether these radio waves might be powering up otherwise harmless electrons in the Van Allen Belts, turning them into \"killer electrons\" capable of damaging satellites and astronauts. Watch the videos to hear and learn more about this rare recording. || ",
