SpaceX’s Starship represents an unpresented leap in space transportation technology. Its development has been characterized by rapid iteration and ambitious testing schedules. The IFT-3 of Ship 28 and Booster 10, scheduled for the first quarter of 2024, aims to validate critical technologies essential for future lunar and interplanetary missions.
SpaceX, founded by Elon Musk, has consistently pushed the boundaries of space technology. Starship is envisioned as a fully reusable spacecraft capable of carrying humans and cargo to Mars. The IFT-3 follows the second flight test (IFT-2) on November 18, 2023, which demonstrated successful hot staging but experienced telemetry loss after eight minutes of flight. It also integrated many advancements learned from the first IFT-1 on April 20, 2023. The data collected and lessons learned from each flight test are invaluable engineering tools needed to achieve Elon Musk’s ambitious objectives.
Technological Advancements For IFT-3
Building on IFT-2, SpaceX will be incorporating major updates from Flight 2, including electronic Thrust Vector Control (TVC), hot staging, and an upgraded Flight Termination System (FTS).
- Electronic Thrust Vector Control (TVC): An advanced system for precise control of the rocket’s path.
- Upgraded Flight Termination System (FTS): Enhanced safety measures for mission termination if necessary.
- Propellant Transfer Demonstration: A key feature for the HLS, involving transfer from a header tank to a main tank in microgravity.
- Launch Pad Improvements Addition of a water-cooled steel plate for thermal protection and sound dampening. Improvements to the OLM, Orbital Launch Module, and “Mechazzilla,” the chopstick arms used to stack Starship on the booster.
A critical new element planned for IFT-3 is the propellant transfer. This test will likely use two different tanks within Starship, possibly a header tank to a main tank. This test is essential for the Human Landing System (HLS). The test will provide critical data for learning how to transfer propellants between vehicles, a maneuver not yet attempted in space. It involves transferring approximately 10 tons of LOX, liquid oxygen, from one tank to another. This test is part of SpaceX’s Tipping Point contract with NASA and is critical for the future lunar lander’s ability to ferry astronauts to the Moon under the Artemis program.
