A NASA watchdog report says development delays in SpaceX’s Starship rocket could affect the Artemis program’s planned 2028 lunar landing. The spacecraft must complete complex technologies, including in-orbit cryogenic refueling, before it can safely transport astronauts from lunar orbit to the Moon’s surface.
Key Highlights
- NASA watchdog warns Starship development delays could affect Artemis mission timeline for a 2028 lunar landing.
- SpaceX selected in 2021 to build the Human Landing System (HLS) for NASA’s Artemis program.
- Artemis mission design requires more than 10 Starship launches to refuel spacecraft in Earth orbit.
- In-orbit transfer of cryogenic fuels remains one of the biggest technical challenges.
- NASA continues targeting 2028 for the first crewed lunar landing using the Starship lander.
Development delays involving SpaceX’s Starship rocket could threaten NASA’s schedule to return astronauts to the Moon under the Artemis program, according to a report released by the agency’s Office of Inspector General.
NASA selected SpaceX in 2021 to develop a lunar lander version of Starship as the Human Landing System (HLS) for Artemis missions. The spacecraft is intended to carry astronauts from lunar orbit to the Moon’s surface during the program’s crewed landing missions, currently targeted for 2028.
However, the inspector general’s report found that Starship’s development has already slipped by about two years and that several complex technologies still require testing before the system can support human missions.
Starship Refuelling System Presents Key Technical Challenge
A major issue identified in the report is Starship’s reliance on in-orbit refuelling, a process that has not yet been demonstrated at the scale required for lunar missions.
Under the Artemis mission design, more than 10 Starship launches would be needed for a single lunar landing. Tanker spacecraft would carry fuel into Earth orbit and transfer it to the Starship lander before the spacecraft travels to the Moon.
The fuel transfer involves cryogenic propellants, liquid methane and liquid oxygen, which must be kept at extremely low temperatures. Managing these fuels safely in space remains a significant technical hurdle, according to the report.
Artemis Program Faces Tight Schedule
NASA’s Artemis program aims to return astronauts to the Moon for the first time since the Apollo missions in the 1970s and establish a long-term human presence there. The program is also designed to support future exploration missions deeper into space, including potential crewed missions to Mars.
The first crewed lunar landing using Starship is currently scheduled for 2028. However, the inspector general said the timeline may face risks if development milestones are delayed.
Expanding Global Space Competition
The Artemis schedule is also shaped by growing international interest in lunar exploration. China has announced plans to send astronauts to the Moon before 2030, while several countries, including members of the European Space Agency, Japan, and Canada, are participating in the Artemis program.
The broader space sector continues to expand. According to the Space Foundation’s “Space Report 2024,” the global space economy exceeded $570 billion in 2023, driven by growth in launch services, satellite infrastructure, and government exploration programs.
Within this market, reusable launch systems like Starship are expected to play a central role in supporting large-scale missions and reducing launch costs.
NASA said it continues to monitor progress in Starship development while maintaining the current Artemis schedule.
