"These increases are caused by interrelated issues such as assumptions that the use of heritage technologies from the Space Shuttle and Constellation Programs were expected to result in significant cost and schedule savings compared to developing new systems for the SLS," the audit states. The older technology isn't helping with the budget as NASA expected, though. It also uses solid rocket boosters provided by Northrop Grumman. Once those run out (all engines on SLS are expendable), NASA will switch to RS-25E engines being built by Aerojet Rocketdyne, which are supposed to be 30 percent cheaper and 11 percent more powerful. The SLS, which finally launched for the first time in November 2022, uses four RS-25 engines per launch, including 16 salvaged from retired Space Shuttles. That sum represents "$6 billion in cost increases and over six years in schedule delays above NASA’s original projections," the report states. NASA's spending on the Artemis Moon Program is expected to reach $93 billion by 2025, including $23.8 billion already spent on the SLS system through 2022. ![]() ![]() Furthermore, the report foresees "additional cost and schedule increases" that could potentially jeopardize the entire Artemis mission if problems aren't handled. NASA's Space Launch System (SLS) rocket designed to take astronauts to the moon is over budget and far behind it's original schedule, according to a scathing new audit from NASA's Inspector General.
