The launch director has given the go-ahead for technicians to empty the rocket's tanks and perform other safety duties.

Engineers discovered a hydrogen leak early in the loading process but were able to fix it.

New cryogenic loading methods and ground automation prevent leaks caused by sudden temperature or pressure shifts during tanking.

To reduce schedule risk during launch day's countdown, engineers calibrated engine conditioning parameters and validated timeframes with a pre-pressurization test.

Without a pilot, the Artemis I flight test will be carried out.

NASA's Artemis missions will send the first woman and person of colour to the Moon.

This will allow a permanent lunar presence and help bring humans to Mars.
