Moon Mission Fuel Needs Could Mean 22 Rockets

Returning to the lunar surface is set to require a massive launch campaign, with a new estimate pointing to a figure of 22 rocket flights. The number, if confirmed, represents a significant logistical hurdle for NASA's Artemis Program and the upcoming missions designed to carry astronauts back to the Moon.

This specific figure has historically been a closely guarded secret within NASA, with the agency refusing to confirm the exact number of launches required to prepare a Starship-based lunar lander for its voyage. The lander, which operates in low-Earth orbit, must be fully fueled by other Starships before it can travel to the Moon, land, and return to lunar orbit.

The requirement for fueling has been a subject of speculation for years. Officials have previously offered vague estimates, citing numbers ranging from single digits to the 'high teens.' The goal has always been to reduce this count by increasing the lift capacity of the SpaceX Starship rocket, which would lower the number of tanker flights needed for each mission.

However, concerns have emerged among some NASA officials regarding the pace of these improvements. There is apprehension that Starship's capacity may not increase quickly enough to fulfill its planned role in returning humans to the Moon for NASA as part of Artemis this decade.

The potential scale of the launch campaign was discussed during a quarterly meeting of the NASA Aerospace Safety Advisory Panel on Thursday. The panel is tasked with reviewing safety risks associated with the Artemis Program and landing humans on the Moon.

During the meeting, panel member Charlie Precourt, a former NASA astronaut, addressed the matter of risks associated with the program. The discussion highlighted ongoing concerns about the logistical and safety implications of the proposed mission architecture.

The source article does not provide further details on the specific risks identified by Precourt or any further explanation for the 22-launch estimate. The figure was mentioned in the context of discussing the challenges and risks of the Artemis Program.

The next steps for the program would involve addressing these concerns and potentially re-evaluating the mission plan to meet safety and scheduling requirements. The agency must balance its ambitious goals for lunar exploration with the practical realities of launch logistics and safety protocols.

The launch estimate for the lunar lander remains a critical factor in the timeline for the Artemis Program. The agency's plans for future missions will depend on its ability to address the logistical challenges associated with such a large number of launches.
