Q&A with Bruce Banerdt, principal investigator on NASA’s InSight mission (members only)

An unpiloted demonstration flight of Boeing’s Starliner crew capsule ended prematurely Sunday with a smooth airbag-cushioned predawn landing in New Mexico after a timing glitch prevented it from docking with the International Space Station, leaving some test objectives incomplete as NASA begins analyzing data to determine if astronauts should fly on the next Starliner mission.

The Emirates Mars Mission, the first deep space probe from the Arab world, steered into orbit around the Red Planet on Tuesday to cap a 307 million-mile (494 million-kilometer), 205-day interplanetary voyage from Earth and begin a science mission studying the Martian climate. The critical 27-minute Mars Orbit Insertion maneuver began at 10:30 a.m. EST (1530 GMT).

A Chinese small satellite launcher failed after liftoff Saturday, destroying a commercial Earth-imaging payload before it could enter orbit.
