The Space Launch System (SLS) rocket program has been in development for over 15 years, plagued by high costs and slow progress. So far, it has cost taxpayers more than $30 billion. Despite its monumental engineering, the SLS has faced numerous setbacks, particularly highlighted by a series of failed attempts to conduct fueling tests. These tests are critical for ensuring the rocket can launch safely, but issues with its hydrogen propellant have led to multiple scrubs of planned launches. NASA's efforts to get the SLS off the ground have been marked by frustration. In March 2022, the rocket was rolled out for a wet dress rehearsal, but the first three attempts were unsuccessful. After extensive delays, the rocket finally launched on November 16, 2022, after a total of seven tries to fully prepare it. The early attempts revealed persistent hydrogen leaks, which raised concerns about the rocket's reliability. Despite the successful launch, there’s skepticism about whether NASA has effectively resolved the underlying problems that caused the delays in the first place.
