Live coverage: Chinese sample return spacecraft completes docking in lunar orbit

Crew members on the International Space Station over the weekend continued trying to pinpoint the location of a small air leak in the research outpost’s Russian Zvezda service module, one of the oldest sections of the orbiting laboratory.

Russia’s Proton rocket took off on its first launch of the year Sunday with a commercial satellite to expand Inmarsat’s next-generation mobile communications network. Liftoff occurred at 1231 GMT (7:31 a.m. EST), and it took more than 15 hours to place the Inmarsat spacecraft in the correct orbit.

SpaceX has revealed the flight plan for the first orbital test launch of the company’s huge stainless steel Starship rocket, a 90-minute, around-the-world mission that will originate from South Texas and culminate with a controlled re-entry and splashdown in the Pacific Ocean near Hawaii.
