NASA's Artemis Moon Rockets: Construction, Testing, and Training for Historic Lunar Mission

NASA's Artemis program, which aims to send astronauts back to the Moon, is progressing well despite a welding issue that has temporarily slowed production on the third core stage. All four RS-25 core stage engines have been successfully installed onto the booster of the second Space Launch System (SLS) rocket. The revamped RS-25 engines have also undergone a successful certification test. However, NASA is facing criticism over the sustainability and affordability of the project, with doubts raised about the $4.2 billion per launch cost of the fully expendable SLS Moon rocket.

Artemis II Moon Rocket Core Stage Nears Final Assembly as NASA Prepares

NASA and its partners have successfully installed all four RS-25 engines onto the core stage of the SLS rocket for the Artemis II mission, marking a significant step towards the completion of the core stage. The core stage, which includes two propellant tanks and four engines, will provide the necessary thrust for the first eight minutes of flight during the crewed mission to the Moon. Engineers are conducting final integration testing before the stage is shipped to NASA's Kennedy Space Center in Florida.

NASA's Artemis II Moon Rocket Fully Equipped with Powerful Engines

The core stage of NASA's Artemis 2 moon mission's Space Launch System rocket now has all four RS-25 engines mounted. The engines, two of which are recycled from the space shuttle program, were installed between September 11 and September 20. The next steps include securing the engines to the stage and integrating propulsion and electrical systems. The rocket will be tested at the launch pad next year before the Artemis 2 mission, which aims to send four astronauts and their Orion spacecraft on a round-the-moon mission.

NASA's SLS Program Faces Budget Woes and Delays.

NASA's Office of Inspector General (OIG) has reported that the conversion of shuttle-era solid rocket boosters and engines for use on the Space Launch System (SLS) has cost the agency billions more and taken years longer than originally planned. The contracts, covering development and production of the boosters and engines, originally had a combined value of $7 billion over 14 years. The cost-plus contracts are now worth at least $13.1 billion over 25 years, of which $8.6 billion has been spent to date. The OIG reported that the overruns have the effect of increasing the cost of a single SLS mission through Artemis 4 by $144 million, to $4.2 billion each.

NASA's Artemis Program Goes Over Budget by Billions.

NASA's Artemis Moon program is $6 billion over budget and six years behind schedule, with the Space Launch System (SLS) rocket being a major contributor to the overrun. The program is on track to reach a $93 billion price tag, with $23.8 billion already spent on the SLS. The report blames the added complexity of integrating old technology into the new for the costly delays to the SLS development. The Inspector General warns that the program's scheduled missions are in great jeopardy so long as NASA continues its spending trend.
