NASA Attaches 186-Block Heat Shield to Artemis III Orion as SLS Booster Stacking Begins

Q: Will Artemis III astronauts actually enter the SpaceX and Blue Origin lander prototypes during their orbital rendezvous?

No. Based on NASA’s revised Artemis III plan, astronauts are expected to enter the Blue Origin lander prototype, but not the SpaceX Starship prototype. The clearest evidence concerns Blue Origin’s Blue Moon pathfinder. NASA’s plan for the low Earth orbit test says Orion will dock with the Blue Moon vehicle for about two days, and that the crew will conduct demonstrations including entering the lander, operating hatches, and checking life-support and suit procedures. Reporting on the mission also says astronauts may practice Axiom suit operations inside Blue Origin’s cabin. SpaceX’s Starship HLS pathfinder is different. The test article for Artemis III is described as a docking target with key interface hardware, not a fully outfitted crewed cabin. Multiple reports say it will not carry the crew cabin configuration needed for astronaut ingress on this mission. In other words, Orion is expected to rendezvous and dock with Starship for systems checks and operational testing, but not for the crew to go inside. That distinction fits the mission’s new purpose. Artemis III is now an orbital shakedown of rendezvous, docking, and related procedures ahead of Artemis IV’s planned lunar landing mission in 2028. So the likely scenario is hands-on internal testing with Blue Origin’s vehicle, and external docking validation with SpaceX’s.

Last week, technicians at Kennedy Space Center installed the Artemis III Orion crew module’s heat shield, clearing the spacecraft for final preparations to mate the crew and service modules.
The shield uses 186 Avcoat ablative blocks and incorporates design upgrades aimed at more uniform performance after NASA analyzed unexpected heat-shield behavior on Artemis I.
Artemis III launch hardware is advancing in parallel: twin SLS solid rocket booster segments began stacking in July, while the core stage was joined to its engine section in May and the first two RS-25 engines arrived in June.
NASA has also started monthly launch countdown simulations at Kennedy, rehearsing propellant loading and the final 10 minutes before liftoff ahead of the crewed mission.
The mission, planned for next year, will send astronauts to low Earth orbit to test Orion docking with commercial human landing system versions needed for Artemis IV’s planned 2028 Moon landing.

Overview

NASA is moving full steam ahead with Artemis III, making strong progress on assembling flight hardware at Kennedy Space Center. The first shipment of booster motor segments, which will provide over 75% of the SLS rocket’s thrust at liftoff, has already arrived, with a second shipment expected soon. This hardware readiness is part of a broader effort to prepare for the 2027 mission, which now focuses on risk reduction and technology demonstration in Earth orbit. These steps reflect NASA’s commitment to learning from past missions and ensuring crew safety through continuous improvement and careful system evaluation.
