Solar storms: beautiful lights, but a hidden danger for astronauts!
While many of us on Earth were captivated by the stunning auroras dancing across the night sky, a different reality unfolded for astronauts aboard the International Space Station (ISS). Recent intense solar storms, which painted the heavens with vibrant colors, also posed a potential threat to those in orbit.
During the nights of November 11th and 12th, powerful coronal mass ejections (CMEs) erupted from a highly active sunspot group, AR4274. These CMEs triggered widespread auroras across the Northern Hemisphere. But here's where it gets controversial... the same energized particles that create these mesmerizing light displays also carry heavy, radioactive ions. These ions can be hazardous to astronauts who aren't protected by Earth's natural magnetic shield.
As a precautionary measure, some ISS crew members had to adjust their sleeping arrangements. Russian cosmonauts Oleg Platonov, Sergey Ryzhikov, and Alexey Zubritsky were instructed to relocate their sleeping quarters for the night. According to Sandra Jones, a NASA public affairs official, the USOS crew remained in their usual sleeping areas, while the Roscosmos cosmonauts took shelter in the lab. The crew also received a list of areas within the ISS to avoid during the solar storm.
And this is the part most people miss... The ISS does have some shielding, but the risk from solar radiation is still significant during these events. Besides the Russian cosmonauts, the ISS Expedition 73 includes NASA astronauts Mike Fincke, Jonny Kim, and Zena Cardman, along with JAXA astronaut Kimiya Yui. The latter four arrived at the ISS in August via a SpaceX Dragon spacecraft and are scheduled to stay for another three months.
With the U.S. government shutdown resolved, American astronauts have resumed their online presence. Jonny Kim, for instance, shared a captivating video of an aurora from space, captured in September.
