Solar Storms: Effects on Satellites
This story is a supplement to the feature "Bracing the Satellite Infrastructure for a Solar Superstorm" which was printed in the August 2008 issue of Scientific American.
Feeling the Full Brunt
The harshness of space takes a toll on satellites even at the best of times. A superstorm would cause years’ worth of damage within a few hours.
Solar particles and radiation puff up the atmosphere, increasing the drag forces on low-orbiting satellites.

How to Prepare
If a storm were on its way, we could do the following:
Satellite operators put off critical command sequences. During the storm itself, they monitor their birds and override any spurious commands.
GPS users switch to backup navigation systems.
Astronauts avoid space walks.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
