SpaceX's latest Starship vehicle has begun flexing its considerable muscle.
SpaceX conducted a "static fire" test today (Dec. 20) with the Starship upper-stage prototype known as Ship 28, briefly igniting the vehicle's Raptor engines while it remained anchored to the pad at the company's Starbase site in South Texas.
Ship 28 is being prepped to conduct Starship's third test flight, which SpaceX aims to launch in the coming weeks. And that timeline apparently remains in target, for today's trial went well.
"Flight 3 Starship completed a full-duration static fire with all six of its Raptor engines," SpaceX said this afternoon in a post on X (formerly known as Twitter), which also featured video of the test.
Starship consists of two elements: a huge first-stage booster called Super Heavy and a 165-foot-tall (50 meters) upper-stage spacecraft known (somewhat redundantly) as Starship.
Both of these stages are designed to be fully and rapidly reusable, and both are powered by SpaceX's next-generation Raptor engine. Super Heavy sports 33 Raptors and Starship is powered by six of them, as SpaceX's post on X today noted.
Starship has flown twice to date, on test flights in April and November of this year. Both missions aimed to send the upper stage most of the way around Earth, targeting a splashdown in the Pacific Ocean near Hawaii.
Neither flight achieved that goal. Starship suffered a number of problems during its April debut, most notably the failure of its two stages to separate as planned, and SpaceX detonated the vehicle intentionally four minutes after liftoff.
Flight 2 notched some major successes, among them stage separation and a nominal first-stage engine burn. But it too ended early, with the explosion of the upper stage about eight minutes after launch.
Starship Die Cast Rocket Model Now $69.99 on Amazon.
If you can't see SpaceX's Starship in person, you can score a model of your own. Standing at 13.77 inches (35 cm), this is a 1:375 ratio of SpaceX's Starship as a desktop model. The materials here are alloy steel and it weighs just 225g.
Note: Stock is low so you'll have to act quickly to get this.
SpaceX wants to get Starship aloft again soon, as shown by the current testing of Ship 28 and its flight partner, a Super Heavy prototype called Booster 10.
It's unclear when that will happen, however. Even if testing continues to go well, SpaceX may still have to wait a while for a launch license from the Federal Aviation Administration. The FAA is overseeing an investigation into what happened on Flight 2; it won't grant a license until that inquiry is done and SpaceX has implemented corrective actions, if any are required.

Why do these spacecraft keep blowing up?Reply
Because they are test flights and SX pushes things to the point of failure sometimes. Knowing what you do know is fine but you really don't learn anything new A proper test flight, you're trying to find out what you don't know for sure. I have found most of the best "learning lessons" in life have happened with my failures.vadertime said:Why do these spacecraft keep blowing up?
The only way you learn to hit a curve ball by missing it and striking out.
If you listen to all the old-timers from Apollo, they all say without the Apollo 1 fire most likely they would of never made it to the moon. Yes it was a horrible event, but it forced them to make the necessary fixes to the systems that needed to be made. I rather the explosions happen with these test test flights with no one on board.
In the long run, you're going to move along faster because you can fix problems and/or optimize as you're developing the systems not at the end when 99% of the development is finished.
For example, hot staging was tested in the last flight and they addressed the other engine out problems from the 1st flight. They also tested the re-designed Flight termination systems that didn't work properly in the 1st flight. They also discovered an issue with re-firing the SH stage, after staging. The real time data from an actual flight will help them refine their simulators to develop a better solution.
Considering SX had a few more rockets built and ready to go it really isn't a big deal that these rockets blew up.
Just knowing something basically is working properly via an actual flight, allows a freedom to move forward with confidence. Also knowing EXACTLY where it failed is maybe much much more important.
