Live coverage: Space station crew safely returns to Earth

A Soyuz booster and Fregat upper stage carried a Russian Glonass navigation satellite into orbit Monday from the Plesetsk Cosmodrome, Russian space officials said.

The pace of the European Space Agency’s development of a power and propulsion module for NASA’s Orion crew capsule will likely determine when an unpiloted test flight of the spaceship and its heavy-lift rocket will take off, NASA officials said last week.

After years of studies, test-firings and a survey of U.S. industry in preparation for launch of a Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.
