Live coverage: Space station crew back on Earth

Orbital ATK readied an upgraded Antares rocket for launch Monday from Wallops Island, Va., to deliver more than 3 tons of crew supplies, science gear, spare parts and three small satellites to the International Space Station to test miniaturized, low-cost technologies for Earth observation applications.

NASA’s Transiting Exoplanet Survey Satellite, fresh off a two-year extension to keep operating through 2022, has turned its cameras to image the northern sky after cataloguing nearly 1,000 candidate planets around other stars in the first year of its mission.

After replacing a faulty inertial measurement system blamed for a scrubbed launch attempt Sunday, a Soyuz rocket headed to space from French Guiana today with five satellites, including the next spacecraft for Europe’s multibillion-dollar Earth observing network and a French experiment to probe the validity of Einstein’s theory of general relativity.
