NASA's Mission Through Dangerous Space Is Going Out in Style
Released on February 11, 2019
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.
