SpaceX Starship’s cutting-edge docking system undergoes tests with NASA to prepare for moon missions

The Importance of Extensive Testing for Moon Missions

Repetition leads to excellence, a principle that holds true for moon missions featuring astronauts. Recently, SpaceX and NASA collaborated on over 200 docking scenarios involving Starship hardware. Starship, the landing system scheduled to transport astronauts to the lunar surface during the Artemis 3 mission, is set for launch no sooner than 2026.

Engineers at NASA’s Johnson Space Center engaged in a 10-day testing period utilizing hardware from both the Starship lander and NASA’s Orion orbiter (constructed by Lockheed Martin) while exploring “various approach angles and speeds,” as described by NASA officials. This real-world testing, conducted with full-scale hardware, serves to validate the computer models of the moon lander’s docking system, according to the agency’s recent announcement.

The upcoming Artemis 3 moon landing requires two spacecraft: the Orion capsule, responsible for transporting astronauts to lunar orbit, and the Starship lander, designed to safely guide astronauts to the moon’s south pole. NASA envisions establishing a permanent base in this region to utilize its potential water ice, which could facilitate fueling and other mission requirements.

The testing positioned Starship as the active docking entity, acting as the “chaser” to the Orion target docking system, as per NASA representatives. The goal was to confirm that SpaceX’s soft capture system could successfully extend to Orion while Orion’s passive system remained retracted. The two pieces of hardware are joined using a combination of latches and other mechanisms.

Although Starship has yet to reach Earth’s orbit, its lunar docking system boasts significant flight experience, as it is derived from the Dragon 2 docking system employed in International Space Station missions. In upcoming missions post-Artemis 3, Starship will be docking with Orion at NASA’s Gateway space station for astronaut transfers.

In 2021, SpaceX clinched the Human Landing System (HLS) contract for the NASA-led Artemis program, aimed at landing a multi-national coalition on the moon’s surface under the Artemis Accords. NASA initially intended to select multiple vendors, making the single-source award to SpaceX a surprising turn of events.

Competing companies Blue Origin and Dynetics raised concerns regarding the HLS contract award, citing acquisition flaws and other issues in the process. Despite filing protests with the Government Accountability Office, these were ultimately rejected, with the GAO stating that NASA’s decision did not display “competitive prejudice.” The U.S. Senate later directed NASA to choose a second company for the project, leading to the selection of Blue Origin and its Blue Moon lander system.

In 2023, Starship underwent two test flights in an effort to achieve Earth orbit, demonstrating its capability for future space missions.
