One of SpaceX’s Falcon 9 rocket boosters made its second trip into space Friday, lofting a Bulgarian television broadcasting satellite from launch pad 39A at NASA’s Kennedy Space Center in Florida, then landing on a platform in the Atlantic Ocean. Liftoff occurred at 3:10 p.m. EDT (1910 GMT).

The United Launch Alliance Atlas 5 rocket lifted off Thursday night at 10:44 p.m. EDT (0244 GMT) with NASA’s four formation-flying MMS satellites.

Russian cosmonaut Anatoly Ivanishin, Japanese flight engineer Takuya Onishi and NASA astronaut Kate Rubins departed the International Space Station on Saturday and headed for a homecoming in Kazakhstan to wrap up a 115-day expedition in orbit. Undocking occurred at 8:35 p.m. EDT Saturday (0035 GMT Sunday), with an on-target landing more than three hours later at 11:58 p.m. EDT (0358 GMT).
