Q&A with Jeff Bezos, founder of Blue Origin

SpaceX fired three Raptor engines on a prototype of the company’s Starship vehicle Tuesday, accomplishing another milestone on the road toward testing of the methane-fueled rocket at higher altitudes.

NASA astronauts Doug Hurley and Bob Behnken returned to Earth Sunday with an on-target splashdown in the Gulf of Mexico at 2:48 p.m. EDT (1848 GMT) Sunday. The astronauts completed a two-month stay on the International Space Station on a test flight of SpaceX’s Crew Dragon spacecraft.

A senior NASA official said Tuesday that the Space Launch System, a huge heavy-lift rocket years behind schedule, could launch astronauts on a moon landing mission in 2024 on just its third flight to meet a goal announced last month by Vice President Mike Pence, while commercial companies will be entrusted with more responsibility to develop a lunar lander and a modest mini-space station, or Gateway, in lunar orbit.
