Live coverage: Atlas 5 blasts off with Navy satellite

Indian ground teams lost contact with a robotic lunar lander and rover minutes before their scheduled touchdown near the moon’s south pole. India was attempting to become the fourth country to achieve a soft landing on the moon.

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.
