• Artemis 1, NASA's first mission to the moon since the Apollo mission in 1972, which was scheduled to launch on 29 August from the Kennedy Space Center, Florida, was called off as a result of engine problems and fuel leaks.

• Launch controllers were still investigating why a bleed test to get the RS-25 engines at the bottom of the core stage to the right temperature range for liftoff had failed, and eventually missed the two-hour launch window. Additionally, there were also a series of weather issues throughout the launch window.

• The next available launch day for the mission is 2 September, provided the engine issue can be solved. However, the delay could extend for several weeks if controllers have to roll the rocket back to Kennedy's assembly building to remove the engine.

<ul><li> AnalystQuickTake: Although this project is a giant step for NASA, there have been many hiccups along the way resulting in a five-year delay and a significant deviation from initial budgets with a per launch cost of USD 4.1 billion vs. the USD 500 million per launch cost initially budgeted for. Moreover, Boeing, which was the lead contractor for the SLS, seems to have lagged behind startups like SpaceX in terms of costs and meeting deadlines in recent times. SpaceX beat Boeing to the launch pad with its crewed flight in 2020 while Boeing is yet to launch its crewed flight test. Additionally, SpaceX’s average cost per passenger is USD 55 million, much cheaper than the estimated average cost of USD 90 million for Boeing.
