Live coverage: India’s Chandrayaan 2 moon mission blasts off

NASA has released an image of Saturn’s moons Enceladus and Tethys caught in a rare alignment by the Cassini spacecraft, which is heading for its final close encounter with the icy moon Enceladus Saturday.

SpaceX fired up nine Merlin main engines at the bottom of a previously-flown Falcon 9 booster Saturday at NASA’s Kennedy Space Center, running the rocket through a practice countdown before a scheduled liftoff Jan. 18 with a Crew Dragon capsule to test the human-rated ship’s high-altitude abort capability.

A Soyuz booster and Fregat upper stage successfully delivered an upgraded Russian Glonass navigation satellite to an orbit nearly 12,000 miles above Earth on Saturday.
