NASA's SLS rocket is back at the launch pad as the space agency gears up to launch Artemis 2 astronauts on a mission around the moon next month.

NASA's Artemis II rocket and Orion spacecraft are returning to the launch pad at the Kennedy Space Center in Florida following a wind delay on Friday.

After an overnight Thursday trip back out to the launch pad, NASA's Artemis II rocket will be readied for a historic flight to the moon.

Standing taller than Big Ben's clock tower at nearly 100m, the rocket and its launch platform weigh about 5,000 tonnes. They are being carried by Crawler‑Transporter‑2, a low‑slung, tank‑like vehicle on caterpillar tracks that Nasa built in 1965 to inch Saturn V Moon rockets to the pad.

NASA began moving its Artemis II rocket towards the launch pad ahead of its launch date set for April 1 at the Kennedy Space Center in Florida.

The Artemis II rocket, which will send astronauts around the far side of the moon, is returning to the launch pad after an issue forced NASA to roll the rocket back for repairs last month. NASA hopes to launch the rocket in the beginning of April.
