SpaceX's seventh mission to rendezvous with the International Space Station ended in flames above Cape Canaveral this weekend, a couple of minutes after liftoff. The company's Falcon 9 rocket launched normally, soared toward the cosmos, then blasted into expensive little pieces over the Atlantic, taking with it a few thousand pounds of supplies and equipment.
The failure--the third for a resupply mission in less than a year--is a blow to the space station's scientific mission. It's yet another challenge to NASA's plans to let private companies handle such launches as it trains its sights deeper into space. And it's a setback to SpaceX's ambitious plans to deploy reusable rockets.
The good news is that SpaceX still has a few years to perfect those rockets before they're scheduled to carry people into the cosmos. The space station still has months' worth of supplies to sustain its crew. And NASA's plan to let private companies handle more responsibilities in space remains sound as a matter of public policy.
The recent failures should be recognized as the cost of making progress in spaceflight. New rocket systems fail as often as they succeed. And the string of recent (and unrelated) accidents in supplying the space station--Orbital Sciences lost a rocket in October, and a Russian mission failed in April--convey important lessons of their own as the space program ramps up for more ambitious exploration. As Scott Kelly, an astronaut aboard the station, put it on Twitter after Sunday's accident: "Space is hard."
