NASA's rocket launch has stopped!

NASA will proceed with the second launch attempt of Artemis I on Saturday, with the megarocket's two-hour launch window set to open at 2:17 p.m. Eastern time.

According to SLS program manager John Honeycutt, during the first launch attempt, readings showed that the SLS's

Engine 3 appeared to be 40 degrees Fahrenheit hotter than the desired minus 420 degrees Fahrenheit so the launch was scrubbed.

Other problems during Monday's launch window included storms in the region that delayed the start of propellant loading operations,

a leak at a quick disconnect in an 8-inch line used to fill and drain core stage liquid hydrogen, and a hydrogen leak from a valve used.
