SpaceX's workhorse Falcon 9 rocket hit a bit of a snag this week.
On Monday (Feb. 2), a Falcon 9 successfully launched 25 of SpaceX's Starlink satellites to low Earth orbit (LEO) from California. But the upper stage failed to perform its deorbit burn as planned and ended up crashing back to Earth in an uncontrolled fashion. (The Falcon 9's first stage aced its landing on a drone ship in the Pacific Ocean.)
