An independent report investigating the development of NASA’s new moon rocket has found significant cost overruns and delays that could hurt the agency’s plans to get astronauts back to the moon.
development of the space launch system (SLS) started in November 2011. It had a successful test flight in November 2022six years after its first debut launch in late 2016. The SLS megarocket is intended to return humans to Moon as part of NASA’s Artemis program, but increases in costs related to contracts awarded to Aerojet Rocketdyne and Northrop Grumman for SLS propulsion systems could threaten that goal.
That is according to a 50 page report by NASA Inspector General Paul Martin released by the Office of Inspector General (OIG) on May 25. In all, the four contracts for the rocket’s propellant and engine were initially projected to cost $7 billion over a span of 14 years, but are now projected to cost at least $13.1 billion over nearly 25 years.

“NASA continues to experience significant range growth, cost increases, and schedule delays from its RS-25 engine and booster contracts, resulting in approximately $6 billion in cost increases and more than 6 years in schedule delays above original NASA projections,” the report found.
These significant increases were caused by a variety of longstanding interrelated management issues that impacted both the SLS development campaign and the broader artemis programthe report notes, including “some of which represent potential violations of federal contracting requirements.”
The use of heritage. RS-25 engines and space shuttle thrusters and constellation programs for the new SLS rocket was intended to deliver significant cost and schedule savings in new systems development. But the “complexity of developing, upgrading, and integrating new systems alongside heritage components turned out to be much greater than anticipated,” according to the report.
To remedy this, the report makes a number of recommendations to NASA management to increase the transparency, accountability, and affordability of SLS engine and booster contracts, including changing awards from “cost plus” to a structure of fixed price contract. However, the assessment still finds the enormous cost of SLS difficult for NASA to manage and detrimental to its long term.”moon to mars“plans.
“Without increased attention to these important safeguards, NASA and its contracts will continue to exceed planned cost and schedule, resulting in reduced funding availability, launch delays, and the erosion of public confidence in the ability of the Agency to responsibly spend taxpayer money and meet mission goals and objectives, including the safe return of humans to the moon and then to Mars.”
The report comes at a time of change and change within the space sector. A number of private space companies developing space propulsion and rocket systems arose during the time of SLS development, such as SpaceX starship and Blue Origin’s lunar landerpotentially providing a much more cost-effective means of returning to the moon.
