An earlier docking attempt was called off after problems were discovered with five of the 28 thrusters on the lower portion of the Starliner capsule.

SpaceX's 400-foot rocket is the most powerful booster ever developed, and the system is expected to play an important role in NASA’s efforts to return astronauts to the moon.

This is the first crewed flight of the company's Starliner capsule, which was developed in partnership with NASA to ferry astronauts to and from the International Space Station.

NASA said Tuesday that attempts to fix a malfunctioning gyroscope have failed, so Hubble will operate with just one gyroscope going forward, which will limit its scientific capability.

On Wednesday, Boeing will try again to launch two NASA astronauts on its Starliner space capsule. A day later, SpaceX will conduct another test flight of its Starship megarocket.

The mission by the Chang’e-6 probe was hailed as a success in China, which has made significant advances in its space program.

The mission is the second designed to bring back samples, following the Chang’e 5, which did so from the moon's near side in 2020.

The launch attempt was scrubbed with only minutes to go in the countdown.

NASA astronauts Barry “Butch” Wilmore and Sunita Williams are expected to lift off at 12:25 p.m. ET Saturday from Cape Canaveral Space Force Station in Florida.

Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a star that is 27% of the sun’s size.

Boeing is now targeting June 1 for the first crewed launch of its spacecraft, with backup opportunities on June 2, June 5 and June 6.
