NASA Will Re-Attempt a Launch of the Artemis 1 Mission on Saturday:

The two-hour launch window starts at 2:17 p.m. ET (6:17 p.m. UTC) on September 3. The rocket's Monday launch was scrubbed due to temperature sensor problems.

  Near the end of the Rocker Report [arstechnica.com]:

  [...] The engines must be chilled to very cold temperatures to handle the injection of cold liquid hydrogen and oxygen propellants. After the attempt, NASA's John Honeycutt said he believed the engine had actually cooled down from ambient temperature to near the required level but that it was not properly measured by a faulty temperature sensor.

  Next attempt Saturday ... The problem for NASA is that the sensor cannot be easily replaced and would likely necessitate a rollback to the Vehicle Assembly Building at Kennedy Space Center in Florida, a few kilometers from the launch pad. This would delay the rocket's launch at least into October, and the space agency is starting to get concerned about wear and tear on a rocket that has now been stacked for nearly a full year. Accordingly, NASA is working on a "flight rationale" plan that would allow the rocket to launch without getting good data from the temperature sensor on the engine. The space agency is targeting another attempt on Saturday, September 3, at 2:17 pm ET (18:17 UTC).

  Wishful thinking? Save a couple months and risk a few billion dollars' worth of rockers.

    Sounds more like a "balance of risk" argument - i.e. the risk of *not* launching (roll back to the engine shed, fiddle with the sensor, hope nothing else goes wrong) is greater than the risk of launching.

  Update: NASA has called off this launch due to a hydrogen leak. The next attempt could come as soon as Monday or Tuesday evening, but will depend on what engineers need to do to fix the issue.
