Stephanie Pappas is a contributing writer for Live Science, covering topics ranging from geoscience to archaeology to the human brain and behavior.

In a rare double-whammy space assault, the European Space Agency's Gaia spacecraft was recently slammed by a micrometeoroid and struck by a solar storm, leaving it unable to function properly. But the satellite is now back to routine operations after the near-devastating impact, scientists say.

"Gaia typically sends over 25 gigabytes of data to Earth every day, but this amount would be much, much higher if the spacecraft's onboard software didn't eliminate false star detections first," Edmund Serpell, Gaia spacecraft operations engineer at the European Space Operations Centre, said in a statement."Both recent incidents disrupted this process. As a result, the spacecraft began generating a huge number of false detections that overwhelmed our systems.
