Can a Spacecraft Survive Without Power in Space?

In space, losing power is a huge problem for a spacecraft. Without power, the systems controlling navigation, communication, and even life support (if it's a crewed mission) can shut down. Some spacecraft have backup batteries, but those only last so long. If solar panels get damaged or blocked, there's no way to recharge, and the spacecraft could drift aimlessly. It’s not all doom, though—clever engineers design fail-safes, like systems that reboot or reroute power in emergencies. But still, power loss in space is a bit like a car running out of gas in the middle of nowhere—except you can’t call for a tow truck! Learn more about your ad choices. Visit megaphone.fm/adchoices
