NASA’s Space Launch System (SLS), an immense rocket pivotal for future space exploration, faces uncertainty as discussions about its future intensify. This controversial project has been marred by high costs and numerous delays, raising concerns about its viability. Currently, SLS remains unmatched in its capacity for heavy payload launches, with very few alternatives available. The only active substitute, developed by a major private aerospace company, has sparked debates about dependency on a single solution amidst these challenges.
