In recent developments, SpaceX is advancing its plans for a new test flight of its Starship vehicle, garnering significant attention from NASA. The space agency is keenly observing SpaceX’s progress, especially since it is critically linked to the development of the lunar lander version of Starship, a vital element for NASA’s future lunar missions.
SpaceX recently announced that it is gearing up for the fifth integrated test flight of its Starship system, with the launch tentatively scheduled for October 13, pending regulatory approval. The mission is set to resemble the fourth test flight conducted in June, where the Starship’s upper stage will follow a suborbital path, ultimately splashing down in the Indian Ocean. This test is a pivotal part of SpaceX’s broader strategy to ensure the reliability and reusability of its spacecraft.
One key aspect of this upcoming mission is the attempted return of the Super Heavy booster to the Starbase launch site in Boca Chica, Texas. The idea is for the launch tower to “catch” the booster using mechanical arms, positioning it back onto the launch mount. This process is crucial for SpaceX’s long-term goals of achieving rapid reusability of their launch vehicles. Rapid reusability means that the same booster can be used multiple times, significantly reducing the cost and resources required for space missions.
SpaceX has outlined that for a successful return and catch attempt, numerous vehicle and pad conditions need to be satisfied. This includes ensuring all systems on both the booster and the tower are functioning optimally, alongside a manual command from the mission’s Flight Director. Should these conditions not be met, the booster will instead be directed to splash down in the Gulf of Mexico as a contingency.
The timeline for this launch has caught many off guard, particularly due to previous indications from the Federal Aviation Administration (FAA) that it would not be in a position to issue a launch license until late November. This was attributed to modifications in the mission profile from earlier flights. The delay has sparked criticism from SpaceX, its CEO Elon Musk, and various industry groups, alongside supportive voices in Congress. It highlights the ongoing tension between regulatory processes and the fast-paced innovation characteristic of private space companies like SpaceX.
In September, an FAA official defended the timeline for the Starship launch license, noting that it was largely driven by an environmental review process. This entails coordination with multiple agencies to ensure that the flight does not adversely affect the environment. The FAA mentioned that SpaceX only submitted detailed information in mid-August regarding how the changes in their flight profile might impact the environment, covering a broader area than previously assessed.
In an update on October 8, the FAA stated that it is actively reviewing this new information, with a licensing determination to follow once all requirements are met. Notably, the latest statement from the FAA did not restate a specific timeline, such as the previously mentioned late November target, suggesting a potential acceleration in the process.
Sources within the industry have hinted that the interagency review is progressing more quickly than initially anticipated, raising the possibility that the licensing process could conclude sooner. However, there remains no certainty that everything will be finalized in time to support a launch as early as October 13.
Lori Glaze, acting deputy associate administrator in NASA’s exploration directorate, expressed optimism about the impending Starship flight during a meeting of the National Academies’ Aeronautics and Space Engineering Board on October 9. She mentioned that NASA is eagerly anticipating the flight, which could happen “as early as next week” based on SpaceX’s updates.
NASA’s interest in Starship is closely tied to its role as a lunar lander within the agency’s Human Landing System (HLS) program. This program is integral to the Artemis 3 mission, which aims to return humans to the lunar surface. Glaze emphasized the importance of the Human Landing System as the critical pathway for Artemis 3, underscoring the significance of SpaceX’s progress in this domain.
A major upcoming milestone for the Starship HLS development involves demonstrating a propellant transfer in orbit. This process is essential as SpaceX plans to establish a propellant depot in Earth’s orbit, which will be resupplied by multiple Starship launches. The depot will then fuel the Starship lander for its journey to the moon. Demonstrating this capability is crucial for verifying that SpaceX can manage the complexities involved in such a task.
Another aspect tied to the success of this mission is the rate at which SpaceX can launch “tanker” Starships to supply the depot. Glaze noted that NASA has observed “good progress” in this area, particularly with SpaceX’s construction of a second launch tower at Starbase and the potential to also launch from Florida, thereby increasing their launch capacity.
The upcoming test flight will also see SpaceX attempt to recover and reuse the Super Heavy booster, a key component of their strategy to reduce launch costs. Initially, SpaceX planned to test the booster landing on its sixth flight, but the timeline has been moved up to the fifth flight, highlighting the company’s aggressive development pace.
During discussions, some committee members expressed concerns over the “enormous” number of launches that may be necessary to fully populate the propellant depot. One member estimated as many as 35 launches might be needed, a figure that exceeds any public estimates provided by NASA or SpaceX officials. Glaze, however, did not specify the exact number of launches required for a Human Landing System mission.
In conclusion, the developments surrounding SpaceX’s Starship and its potential use as a lunar lander are being closely watched by NASA and the broader space community. The outcomes of these test flights and the subsequent regulatory approvals will have significant implications for the future of human space exploration, particularly in relation to NASA’s Artemis program. As SpaceX continues to push the boundaries of space technology, the world watches with a mix of anticipation and optimism, eager to see what the future holds for space travel.
