A commercial mission developed by the Japanese company Astroscale rocketed into space on a Russian Soyuz launcher Monday with 37 other payloads, ready to kick off an orbital “dance” with two small spacecraft demonstrating how satellite sweepers might one day drag junk out of orbit.

A SpaceX-owned Dragon supply ship packed with nearly three tons of cargo arrived at the International Space Station on Monday after a three-day trip from Cape Canaveral. The station’s robotic arm grappled the cargo capsule at 6:54 a.m. EDT (1054 GMT).

A veteran Russian cosmonaut, a Japanese flight engineer and a NASA scientist-astronaut undocked from the International Space Station and returned to Earth Saturday, landing on the steppe of Kazakhstan to close out a 115-day mission.
