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.

China’s space program is sprinting toward the end of the year by extending the country’s record-breaking launch rate, with two more space missions lifting off in the last week carrying a pathfinder for a planned constellation of Internet satellites and a mysterious payload heading for geostationary orbit. At least one more Long March rocket is set to lift off Saturday to close out 2018.
