SpaceX To Attempt Daring Orbital Refueling Test of Starship (gizmodo.com) 98
SpaceX plans an ambitious in-orbit refueling test between two Starships in March 2025. "The orbital demonstration is a major step for Starship, and a crucial part of SpaceX's capability of delivering NASA's Artemis mission to the Moon," reports Gizmodo. The plans were unveiled during Spaceflight Now's recent interview (source: YouTube) with Kent Chojnacki, the deputy manager for NASA's Human Landing System program. Gizmodo reports: SpaceX is under a $53.2 million contract with NASA, signed in 2020, to use Starship tankers for in-orbit propellant transfer. During its third test flight, SpaceX transferred around 10 metric tons of liquid oxygen from Starship's header tank to its main tank while it was in space. The upcoming demonstration, however, requires a lot more of the launch vehicle. Two Starships will launch to low Earth orbit around three to four weeks apart, the spacecraft will meet and dock in orbit, and one will transfer propellant to another. After the demonstration, the two Starships will undock from one another and deorbit.
"Once you've done that, you've really cracked open the opportunity to move massive amounts of payload and cargo outside of the Earth's sphere," Chojnacki said during the interview. The in-flight propellant transfer tests are set to conclude in the summer. With in-flight refueling, NASA is aiming to develop technologies to "enable long-term cryogenic fluid management, which is essential for establishing a sustainable presence on the Moon and enabling crewed missions to Mars," the space agency stated when the contract was signed.
SpaceX is developing a version of Starship to land humans on the Moon in September 2026 as part of NASA's Artemis 3 mission. To prepare for the Moon mission, SpaceX is expected to launch between eight and 16 propellant tanker Starships into low Earth orbit in rapid succession. Each of the tankers will carry around 100 to 150 tons of liquid oxygen and liquid methane and will dock with a larger fuel depot. The orbiting depot will then connect with the Human Landing System Starship, filling its massive 1,200-ton fuel tanks. Once refueled, the Starship lander will continue its journey toward the Moon.
