In a recent audit report, Artemis Programs: NASA Should Document and Communicate Plans to Address Gateway’s Mass Risk, the Government Accountability Office (GAO) expressed some concerns about NASA’s Gateway space station, which will orbit the moon as part of Artemis IV . Specifically, the concerns relate to the first components of the space station to be launched in December 2027 —the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO).
In the report, GAO states:
The Gateway program’s projects—including PPE and HALO—made varying degrees of progress over the last year. However, the PPE and HALO projects face several significant challenges. For example, their combined mass is greater than their mass target. Mass is one of many factors that the program considers in its overall design. If they cannot meet their mass target, it may affect their ability to reach the correct lunar orbit.
The report goes on to state:
For example, program officials estimate that the mass of the lunar lander Starship is approximately 18 times greater than the value NASA used to develop the PPE’s controllability parameters.
NASA agrees with the single GAO recommendation in this report, which recommends that a mass management be ready for an upcoming review in September 2024.
There is a lot to read in the 52 page report, but the real question is whether NASA will be ready for the 2027 Gateway launch. This is a ongoing concern given that we are already seeing delays in other parts of the Artemis program.
