Astrobotic, a Pittsburgh-based company developing a robotic lunar lander, will launch its first moon mission under contract to NASA on the debut flight of United Launch Alliance’s Vulcan Centaur rocket in 2021, officials announced Monday.

Orbital ATK’s Minotaur-C rocket, formerly known as the Taurus, has launched for the first time in six years from Vandenberg Air Force Base in California. The solid-fueled launcher lifted off with 10 commercial Earth-imaging satellites at 2:37 p.m. PDT (5:37 p.m. EDT; 2137 GMT) Monday.

A Russian Soyuz crew ferry craft departed the International Space Station and descended to an on-target landing in Kazakhstan on Saturday with a record-setting NASA astronaut, a veteran Russian cosmonaut and a former U.S. Air Force test pilot on-board. Undocking from the orbiting research complex occurred at 2158 GMT (5:58 p.m. EDT), with touchdown at 0121 GMT (9:21 p.m. EDT).
