A U.S.-Russian-Italian space crew closed out a 199-day expedition on the International Space Station with a parachute-assisted landing Thursday on the steppe of Kazakhstan. Touchdown of the Soyuz TMA-15M spacecraft occurred at 1343 GMT (9:43 a.m. EDT).

A European environmental satellite designed to monitor Earth’s oceans, lakes and vegetation lifted off Wednesday aboard a modified Russian ballistic missile originally built to carry nuclear warheads. The mission launched from the Plesetsk Cosmodrome around 500 miles north of Moscow at 1757:51 GMT (1:57:51 p.m. EDT).

Within days, NASA is expected to select a winner from a roster of nine eligible companies to try and become the first commercial entity to accomplish a soft landing on the moon with a robotic spacecraft. The privately-developed probe would be the vanguard in a series of unpiloted missions intended to deliver science instruments to the lunar surface and prepare for a human expedition as soon as 2024.
