Jeff Bezos has claimed that the second flight of his New Shepard spaceship is successful.
Intended eventually to carry people just above the atmosphere, the re-usable vehicle launched from west Texas on Monday with no-one aboard.
Both parts of New Shepard – the capsule and its propulsion unit – landed safely, Mr Bezos’ company said.
On the maiden outing in April, the propulsion module was lost on the way down because of a hydraulic failure.
True to his way of working, the US billionaire gave no specific notice of the flight, stating last week only that another mission would occur “very soon”
