NASA’s Human Landing System: Starship’s Role in Artemis Missions
NASA’s ambitious goal of returning humans to the surface of the Moon hinges on the success of numerous components, with one of the critical elements being the lunar lander. SpaceX’s Starship, a variant of the rocket’s upper stage, is slated to play a pivotal role in this endeavor.
Starship and the Artemis Program
The Artemis 3 mission, NASA’s primary lunar exploration project, is planning to use a Starship variant as the lunar lander. The lander will dock with the Lockheed Martin-built Orion spacecraft and facilitate two astronauts’ journey to the Moon’s surface and back. The Artemis 3 mission is currently scheduled to take place in September 2026, following a series of test and developmental phases.
Starship’s Historical Background and Current Milestones
The Starship program traces its origins back to 2012. However, it was in 2021 that NASA formally entered the picture with a $2.89 billion contract, which ensured the rocket became a cornerstone of the Artemis 3 launch. A contract modification in 2022 further expanded the plan to include a second crewed landing for the Artemis 4 mission.
Every iterative test launch of Starship, such as Flight 5, has been crucial for NASA in understanding the rocket’s performance and capabilities. In October 2024, during Flight 5, the successful catch of the Super Heavy booster by "Mechazilla" was a significant milestone, signifying the potential for rapid reusability—a key ingredient for SpaceX’s Moon-landing success.
The Role of NASA’s HLS Program
Blue Origin’s lunar lander, Blue Moon, is also part of NASA’s Human Landing System (HLS) program, which collaborates with SpaceX to develop these lunar landing capabilities. Dr. Kent Chojancki, deputy program manager of the HLS office, emphasizes NASA’s interest in the performance metrics of both the booster and the Starship.
Rapid Reusability and Propellant Transfer
Flight 5 highlighted the successful rapid reusability of the Super Heavy booster as SpaceX’s Mechazilla retrieved it. Chojancki highlighted how StarShip’s proposed architecture requires multiple launches to aggregate the necessary propellant in low Earth orbit before going to the Moon. The demonstration of rapid reusability in low Earth orbit is a key factor in making these missions feasible.
Uncrewed Moon Landing Demonstration
Dr. Chojancki underscores the importance of an uncrewed Moon landing demonstration prior to putting astronauts on the Starship. SpaceX must show that its HLS variant can land on the Moon and take off again, a testament to its capability and reliability.
Upcoming Milestones
Looking ahead, Chojnacki points to the long-duration orbital flight and propellant transfer demonstration as a critical next step. This test is proposed by SpaceX and expected to take place in March 2025, offering insights into the long-term viability and efficiency of Starship’s propellant system.
The Collaboration and Future Prospects
The success of Starship is also greatly bolstered by NASA’s technical expertise and collaboration. SpaceX has been receptive to the feedback and improvements suggested by NASA engineers, especially in areas like cryogenic propellant thermal protections. The Astronaut Office, based at the Johnson Space Center, has been integral in refining design elements through ongoing collaborative efforts.
