NASA hopes to launch its crewed Artemis 2 moon mission in early February, but everything will have to go right to hit that ambitious target.

Nasa's mega rocket has been moved to the launch pad in Cape Canaveral, Florida, as the final preparations get underway for the first crewed mission to the Moon in more than 50 years.

The Artemis 2 moon rocket consists of NASA's second Space Launch System rocket and Orion spacecraft, and is scheduled to launch four astronauts around the moon as early as Feb. 6.
