Cybersecurity threats are a growing concern for day-today life on Earth. As thousands of satellites are launched to orbit, are there new risks to consider in the skies above?

Spicer said hackers could theoretically seize control of a spacecraft's propulsion system and cause mayhem in a congested LEO environment.
