NASA’s Artemis 1 rocket is set for another test, with today’s being a “wet rehearsal”, according to ANU astrophysicist and cosmologist Dr Brad Tucker.
The test marks the second attempt at launch after April’s test found a few issues with the rocket.
“You essentially take the rocket, you fill it up, get it ready to launch, you do the countdown, you do all the testing, essentially everything except launch,” he told Sky News Australia.
“The idea here is they want to make sure that the filling up of the fuel and the emergency unfuelling – in the event that the real rocket doesn’t take off, they can pump out the fuel safely – that all of it works.”
Dr Tucker said the wet rehearsal will take approximately 48 hours to complete.
