Video: Antares post-launch news conference

Astronauts Doug Hurley and Bob Behnken give a video tour of their new SpaceX Crew Dragon spacecraft as they close in on a docking with the International Space Station on May 31, 2020.

Peering down at the Earth’s atmosphere from a research window aboard the International Space Station, a new science instrument launching Tuesday will compose unprecedented characterizations of the chemical makeup of shooting stars.

SpaceX is likely to land the first stage of the Falcon 9 rocket set for launch April 30 on a drone ship just off the coast of Cape Canaveral, not at the company’s onshore recovery site as originally planned, after a ground test of the company’s Crew Dragon capsule at the landing pad ended in an explosion Saturday.
