Private spaceflight company Blue Origin, helmed by Amazon founder Jeff Bezos, says it has landed its main rocket, New Shepard, back on Earth after launch. That would make it the first rocket ever to have gently landed and remained intact after taking off into space. It also means that Blue Origin has beaten SpaceX in the race to make the first reusable rocket; the Elon Musk-led space venture has been trying to soft-land its main rocket, the Falcon 9, for the past year.
To commemorate the landing, Bezos tweeted for the first time since setting up his Twitter account seven years ago.
