NASA’s SLS rocket is $6 billion over budget and six years behind schedule – By Steve Dent (Engadget) / May 29, 2023
A new audit states that ‘additional cost and schedule increases’ are likely as well.
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. Furthermore, the report foresees “additional cost and schedule increases” that could potentially jeopardize the entire Artemis mission if problems aren’t handled.
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. That sum represents “$6 billion in cost increases and over six years in schedule delays above NASA’s original projections,” the report states.
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. 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. It also uses solid rocket boosters provided by Northrop Grumman.
