Watch as Falcon 9 launches with 10 Iridium satellites and its first stage lands

SpaceX chief Elon Musk said last week he is “fairly confident” his company’s Falcon rockets can be made fully reusable within a couple of years, suggesting a renewed emphasis on outfitting upper stages for a scorching re-entry after engineers shelved the idea to focus on landing the launcher’s bigger booster stage.

For the second time this year, SpaceX has launched a commercial communications satellite for Tokyo-based SKY Perfect JSAT Corp. A Falcon 9 rocket blasted off at 1:26 a.m. EDT (0526 GMT) from Cape Canaveral with the JCSAT 16 satellite to relay data and video across Japan and the Asia-Pacific. The Falcon 9’s first stage booster nailed a landing on a barge in the Atlantic Ocean a few minutes later.

The 32-story-tall mobile service tower at the Delta 4’s launch pad at Vandenberg Air Force Base in California was retracted away from the rocket Thursday in advance of a planned liftoff with a top secret National Reconnaissance Office payload.
