Watch the astronauts give a tour of their new Crew Dragon spacecraft

NASA announced Tuesday it has awarded SpaceX a $331 million contract to launch the first two pieces of the Gateway lunar outpost in 2024 using a modified version of the Falcon Heavy rocket to hurl the massive core of the deep space station toward the moon.

An atmospheric test article of Sierra Nevada Corp.’s Dream Chaser spaceship made a successful runway landing Saturday at Edwards Air Force Base in California after a glide test flight performed to verify the craft’s handling qualities and guidance systems before future resupply missions to the International Space Station.

Mission leaders Tuesday gave approval for rollout of the United Launch Alliance Atlas 5 rocket to its pad on Wednesday morning, leading to liftoff Thursday evening of a NASA probe to rendezvous with an asteroid and bring a sample back to Earth.
