Former NASA astronaut Mike Massimino reacts to the historic test flight. SpaceX is also building a new drone ship for rocket landings at sea, he added. When SpaceX's Falcon Heavy blasted off last Tuesday (Feb. The Falcon Heavy's two side boosters landed successfully (and simultaneously) on twin pads at the nearby Cape Canaveral Air Force Station, but the center core crashed and burned. That core booster, which was expected to land offshore on SpaceX's drone ship "Of Course I Still Love You," crashed when two of three engines did not fire during a final landing burn, Musk told reporters after the launch.

Remember earlier this month when SpaceX succeeded in landing its Falcon 9 rocket first-stage booster on a drone ship out in the Atlantic for the first time ever (and the first time ever by any private company)? Now the company has released a new 360-degree video of the historic landing on YouTube. Personally, I still prefer the flat video captured from afar.

The Falcon 9 Rocket successfully landed on the droneship Of Course I Still Love You on April 8. There couldn't have been a more perfect launch than yesterday's. The sun was shining, a gentle breeze was blowing, and SpaceX's Falcon 9 rocket took off right on schedule. As we watched from a few miles away, the glare of the rocket's flames was searingly bright, hard to look at but impossible to look away from, like the sparklers kids play with on the Fourth of July. The sound, too, was like Independence Day, the boom and shake of a thousand fireworks going off, crashing through the sound barrier. The cargo made it safely into orbit, where it's on its way to the International Space Station.

Fifth time's the charm: SpaceX has successfully landed the first stage of its Falcon 9 rocket on its droneship out in the Atlantic Ocean, the first time in history such a landing has ever been achieved. All four previous instances of this landing ended in failure. SpaceX hopes to use this type of rocket landing to be able to re-use the first stage of its rockets and dramatically cut the cost of space travel going forward. This landing is a huge step towards that goal, and came during an especially pivotal launch for SpaceX: SpaceX's first cargo re-supply mission to the International Space Station since a Falcon 9 exploded in mid-flight in the summer of 2015, thwarting that particular re-supply attempt. On this mission, SpaceX's uncrewed Dragon capsule -- which sits atop the Falcon 9 rocket and detaches to fly onward to the space station -- was also carrying some really exciting cargo: the first-ever inflatable space habitat designed for the space station, the Bigelow Expandable Activity Module (BEAM).
