NASA Prepares Artemis 3 SLS Rocket for 2027 Test Flight

Core Development: Artemis 3 Rocket Assembly
NASA’s Space Launch System (SLS) core stage for Artemis 3 was hoisted into High Bay 2 of VAB on 10 May 2024; technicians will attach four RS-25 engines and move it to High Bay 3 for integration with upper stage, boosters and Orion. Launch slated for latter half of next year; Artemis aims for 2027.
Background: Artemis Program Progress
Artemis 2 launched 1 April 2024, completing a lunar flyby and Orion’s crewed flight with astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen. Artemis 3 will stay in Earth orbit to test Orion’s docking with one or both lunar landers, a prerequisite for the crewed lunar landing planned for Artemis 4.
Timeline of Milestones
Technical Data
The Artemis 3 core stage measures 212 ft (65 m) and houses four RS-25 engines. When assembled with upper stage, boosters and Orion, the SLS reaches 322 ft (98 m) and weighs 5.75 million lb (2.6 million kg) at full fuel load.
Why It Matters
Docking tests will validate Starship and Blue Moon lander designs, letting NASA certify the vehicle that meets performance criteria. Uncrewed lunar touchdowns on Artemis 3 are required before Artemis 4’s crewed descent and a permanent south-pole base by the early 2030s.
Official Statements & Responses
NASA’s X post said the core-stage lift is a step toward attaching the RS-25 engines and completing vehicle assembly. The agency added that Artemis 3 will launch with any lander qualified at that time, and a successful test will pave the way for Artemis 4’s crewed lunar descent in 2028.
Conflicting Reports & Gaps
The headline mentions a 2027 launch, yet the text cites a target for the latter half of “next year,” creating a date discrepancy. No readiness dates are given for Starship or Blue Moon, leaving the lander choice unclear.
Verbatim Quotes
- “Technicians at @nasakennedy have completed operations of lifting the largest section of the core stage for NASA’s Artemis III SLS rocket into High Bay 2,” — NASA, X post
- “There's nothing better than seeing an SLS rocket stage vertical!” — NASA, X post
- “If they can do that successfully, and also demonstrate uncrewed lunar touchdowns, NASA plans to launch Artemis 4 in 2028 as the program's first crewed moon landing .” — NASA, program briefing
- “Starship is currently the lander contracted for that mission, but the readiness and performance of both landers during Artemis 3 could possibly change that arrangement if Blue Moon completes its qualification testing first.” — NASA, program briefing
What's Next
After Artemis 3’s Earth-orbit test, NASA will certify the lander and aim for Artemis 4’s 2028 crewed lunar landing. Subsequent missions will build infrastructure at the south pole, targeting a permanent outpost by the early 2030s.
