Live coverage: Space station crew investigating slow pressure leak

Boeing and SpaceX are readying for launch abort tests in the coming weeks to validate the crew escape systems for the new human-rated Starliner and Crew Dragon spaceships, now scheduled to begin ferrying astronauts to the International Space Station in the first half of next year.

A novel communications experiment developed by NASA and the Naval Research Laboratory has arrived at the International Space Station to prove data can be transmitted in space using X-ray signals, a breakthrough that could have uses in deep space exploration and military technology on Earth.

A miniature cargo return vehicle carried aboard a Japanese supply ship splashed down in the Pacific Ocean earlier this month in the first test of a new capsule to bring home experiment samples from the International Space Station.
