To protect against cyber attacks in space, researchers are asking, “What if?”

If space systems like GPS were hacked and taken offline, much of the world would immediately revert to the communications and navigation technologies of the 1950s. Yet space cybersecurity has remained largely invisible to the public at a time of heightened geopolitical tensions. Cyberattacks on satellites have been happening since the 1980s, but the global … Read more

Space weather can make it difficult to predict satellite orbits. Here’s why that’s a problem

Satellites in low Earth orbit (LEO) can deviate hundreds of kilometers from their expected trajectory when bad space weather hits. The problem affects the International Space Station, China’s Tiangong Space Station and many Earth observation satellites that need to get up close to our planet. Experts say this positioning uncertainty increases the risk of dangerous … Read more
