Live coverage: 400th Proton rocket takes off with Russian satellite

A commercial Dragon cargo capsule wrapped up a four-week stay at the International Space Station on Monday with a departure from the complex at 12:01 p.m. EDT (1601 GMT). The spacecraft splashed down in the Pacific Ocean at 5:48 p.m. EDT (2148 GMT) with several tons of research specimens and equipment.

A commercial robotic lander developed by the Japanese company ispace was supposed to land on the moon at 12:40 p.m. EDT (1640 UTC) Tuesday, attempting to make history as the first privately-funded enterprise to achieve a controlled touchdown on the lunar surface. But mission controllers lost contact with the spacecraft just before landing.

Continuing a busy week of comings and goings at the International Space Station, a Russian Progress supply ship is set for liftoff at 0709 GMT (3:09 a.m. EDT) Wednesday from Kazakhstan with nearly 5,200 pounds of food, fuel and supplies for the six-person crew on the International Space Station.
