Artemis I takes aim at the Moon

Efforts to get the test mission off the ground hit last-minute snags

- 

At long last, NASA is ready to begin its first foray towards the Moon in 50 years with the launch of Artemis I. The mission is an uncrewed test of the Space Launch System (SLS) heavy launch vehicle and the Orion crew module that will carry future crews to the Moon. But will it make its flight? The initial launch on 29 August was scrubbed after a problem was found on SLS's Engine 3.

"We don't launch until it's right," said NASA administrator Bill Nelson. "I think that this is illustrative that this is a complicated machine. You don't want to light the candle until it's ready to go."
