Live coverage: Space station crew concludes 186 days in orbit

Boeing engineers in New Mexico are readying a Starliner spacecraft for a critical pad abort test this fall to demonstrate the capsule’s ability to escape an emergency on the launch pad before green-lighting the capsule to carry astronauts.

The Falcon 9 booster that launched four astronauts toward orbit last weekend arrived back on Florida’s Space Coast Thursday aboard a SpaceX drone ship, sailing into Port Canaveral with a lean but otherwise in seemingly good shape after it apparently slid across the ship’s deck in high winds and rough seas. Assuming post-flight inspections reveal no major issues, SpaceX aims to reuse the booster to launch the next Crew Dragon mission in 2021.

The first in a new constellation of Russian Arctic weather satellites is poised for launch on top of a Soyuz rocket Sunday from the Baikonur Cosmodrome in Kazakhstan.
