Live coverage: Mission control loses contact with Indian moon lander

Mars rovers go through seven minutes of terror when they plunge into the Martian atmosphere at hypersonic speed. NASA’s OSIRIS-REx spacecraft will take a more glacial approach to its asteroid target Tuesday, and the event will be more akin to four-and-a-half hours of mild anxiety for ground teams, according to the mission’s operations manager.

In the closing months of a nearly 11-year mission, NASA’s Dawn spacecraft has arrived in its final orbit around the dwarf planet Ceres and is obtaining the sharpest views yet of the king of the asteroid belt.

The first of up to 22 launches on Arianespace’s schedule in 2020 successfully delivered a commercial European broadband satellite and an Indian communications payload to orbit Thursday using a heavy-lift Ariane 5 rocket.
