Despite delays and night launch, thousands still expected in Florida to watch Artemis I go

Both of these phenomena have been at play in recent weeks. NASA already scrubbed two attempts at getting the SLS off the ground — the first on August 29 and the second on September 3.

The initial launch attempt was scrubbed after it appeared that one of the rocket’s four main engines was too hot during engine bleed tests.

This issue, however, was later traced to a misleading reading from a “bad sensor”.

A persistent leak in the liquid hydrogen fuel line, meanwhile, brought the second go to a halt, despite engineers trying three times to troubleshoot the problem.

Further delays were caused by Hurricanes Ian and Nicole — the former of which, with sustained wind speeds of up to 150 miles per hour, forced NASA to roll back the SLS from the launch pad to its assembly building for shelter.
