Need for In-Space Rocket Fuel Pumping: SpaceX’s Role In Artemis 1, 2 and 3

    SpaceX’s Starship and rocket fuel are a crucial component of NASA’s Artemis program. The Artemis program, which launched its first successful mission in 2022, aims to send crewed missions to the Moon. However, recent developments have led to a delay in the Artemis 2 and 3 missions, pushing them back by a year.

    In-orbit refueling is a crucial aspect of SpaceX’s Starship architecture. It allows the rocket to compensate for the fuel lost during the first stage of its journey by refilling itself in space. This boosts Starship’s range, making it an ideal workhorse for NASA’s Artemis program.

    The Artemis program has faced a series of challenges that have led to a delay in its timeline. NASA’s Amit Kshatriya revealed that safety concerns, specifically related to the Orion spacecraft’s valves and heatshield, have necessitated a recalibration of the Artemis 2 and Artemis 3 launch timelines.

    In 2024, NASA plans to focus on testing and development, particularly in areas that require continuous risk minimization. This includes the development of new spacesuits and conducting tests on SpaceX’s Starship rocket.

    SpaceX’s Starship rocket plays a pivotal role in the Artemis program. Jessica Jensen from the organization shared that the number of Starship launches needed to set up a propellant depot could be less than ten, depending on the success of flight tests. In-orbit refueling, a key aspect of the organization’s Starship architecture, has been highlighted as a crucial technological demonstration requirement for the Artemis program.

    SpaceX plans to test propellant transfer this year and expand the tests next year. Before the Artemis 3 mission, the organization will also attempt to land Starship on the Moon and test ascent capabilities as part of an uncrewed lunar mission.

    SpaceX ended 2023 on a high note by conducting the second Starship test flight. For the third test flight, the organization aims to be hardware-ready by the end of this month and complete its work with the Federal Aviation Administration (FAA) for the launch license in February.

    The third test will not seek to demonstrate an on-orbit fuel-to-fuel transfer. However, SpaceX might test transfer propellant between Starship’s header and main tanks as part of an on-orbit cryogenic propellant transfer test.

    Jensen concluded by stating that SpaceX “needs” the propellant transfer capability to work and is willing to conduct as many tests as possible to ensure its success. She added that SpaceX has been investing in its production facilities to develop the capacity for successive flight tests.

    Regarding the Orion heatshield, a Lockheed representative explained that only a small area was affected by the heatshield material coming off the ship. The cause of the aberration is unknown, but there was a sufficient margin of untouched heatshield to ensure the safety of any crew members on board.

    Despite the delay to the Artemis mission, Administrator Nelson remains confident that China will not overtake the U.S. in landing humans on the Moon this millennium.
