After a busy day at Starbase in Texas, SpaceX officially announced details of the latest phase of its Starship testing campaign. Earlier today, the company conducted engine tests for Starship's first and second-stage boosters, with each test designed to demonstrate specific results. Specifically, SpaceX's second-stage Starship tilted increasingly during some tests to demonstrate capabilities that may be needed for safe orbital travel.
NASA has a contract with SpaceX to provide the lunar lander for its Artemis lunar mission, and SpaceX shared a second stage on the X earlier today testing the ability of its engines to fire up for maneuvers in space.
Before a rocket passes pre-launch regulatory review, rocket pilots must ensure the rocket does not threaten safety in the air and on the ground. For Starship, that means SpaceX has to go to great lengths to make sure the rocket doesn't go out of control, especially as it attempts to reach orbit.
Therefore, because SpaceX's goal is to enter orbit and then deorbit the second-stage Starship while demonstrating the ability to control the vehicle and refuel it in orbit, the rocket must be tested on the ground to verify that the systems required for safety and control can work properly in space.
SpaceX confirmed that during today's test of the second-stage Starship, the rocket only fired one engine. The company explained that the purpose of the test was to demonstrate engine starting during space flight. This burn is typically done to steer the rocket in space or control its direction during descent. Losing control during descent often means the rocket is uncontrollable and its final destination unpredictable.
One of the biggest constraints on the Starship program is the Raptor engine. In 2020, the first problems encountered by SpaceX during the first Starship test event included engine failure to start, explosion or combustion chamber failure. During Starship's first full-stack orbital test flight attempt in April, the rocket's engines stalled throughout its ascent. This raises questions about its reliability, especially since a single Starship requires 33 engines working together precisely to ensure optimal mission conditions.
SpaceX also confirmed that the static fire test of its first-stage Starship Super Heavy booster involved all 33 engines. This is the first time a static fire test of this type has been carried out, as previous tests only tested a few of the engines. SpaceX shared a video of a 33-engine Starship Super Heavy static fire on its
The decision to add another launch tower to the Starbase has also been finalized. The latest interstellar base map video released by SpaceX shows two fully stacked Starships standing next to each other. SpaceX plans to produce hundreds of Starship first and second stages each year, and the company is upgrading its production base to do so. New additions include a new production site and the previously mentioned second launch tower.
