SpaceX engineers at Starbase located in Boca Chica Beach, Texas, initiated pre-flight testing on Starship SN28, the stainless-steel spacecraft set to embark on the third Integrated Flight Test (IFT-3) alongside Super Heavy Booster number 10. Adorned with Christmas decorations, the spacecraft rolled down Highway 4 towards the launchpad on December 14.
Then, on December 16, engineers conducted a crucial “spin prime test,” simulating propellant loading by spinning or priming the turbopumps within the Starship’s engines using liquid nitrogen. This test ensures proper fuel and oxidizer delivery to the combustion chamber, as previously reported by Cosmic Chronicles.
In a significant step forward, SpaceX proceeded to perform a “static fire” test on December 20, briefly igniting all six Raptor engines on Starship SN28 while anchored to the pad at the Starbase launch site. The successful test marks progress toward the upcoming third test flight. “Flight 3 Starship completed a full-duration static fire with all six of its Raptor engines,” SpaceX announced. The company shared incredible videos of the testing operation that showcases the brief ignition with immense power, linked below. Each Raptor engine is capable of generating around 230 tons of thrust, making it one of the world’s most powerful rocket engines.

Although Starship has faced challenges in its previous test flights in April and November, SpaceX remains committed to advancing its development. The current testing of Starship SN28 signals SpaceX’s determination to achieve successful launches in the near future. The next testing phase will likely be related to Booster 10, which will also undergo testing of its 33 methane-fueled Raptor engines before it takes flight.
Uncertainties linger regarding the launch timeline. SpaceX awaits a launch license from the Federal Aviation Administration (FAA), which is conducting an investigation into the events of the second test flight.
