On Tuesday, SpaceX performed a take a look at launch of its Tremendous Heavy rocket for about 12 seconds, making it the longest launch of an enormous accelerator. The take a look at, which fired 11 of the Raptor’s 33 rocket engines, got here as SpaceX continues work on an orbital launch try for this Tremendous Heavy first stage and its Starship higher stage.

Earlier this month, SpaceX fired 14 Raptor engines on the accelerator for just a few seconds, so Tuesday’s take a look at didn’t set a brand new document for the variety of engines examined. Nonetheless, this “lengthy period” firing is the longest time period that so many Raptor engines have been fired on the similar time.

So what occurs now? The trail to orbit for SpaceX and its Starship launch system is unclear. Previously the founding father of SpaceX – mentioned Elon Musk the following step was to run a subset of the Tremendous Heavy engines for about 20 seconds to check the autogenous strain. This methodology of pressurizing gasoline tanks makes use of gases generated on board the rocket, somewhat than a individually loaded inert gasoline similar to helium.

Tuesday’s take a look at could have been a barely shorter model of that autogenous strain take a look at — 12 seconds as a substitute of 20 — or it could have been one thing else. The corporate takes an iterative strategy to the design and growth of the Starship car and its Tremendous Heavy first stage, so its take a look at plans are fluid, not in contrast to a cryogenic rocket propellant.

In all chance, SpaceX nonetheless has a number of key checks to finish earlier than the mixed Tremendous Heavy rocket and Starship booster will launch from the corporate’s Starbase facility in South Texas. SpaceX is predicted to conduct a minimum of a short-term take a look at run of all 33 Raptor engines concurrently to achieve confidence within the completeness of the rocket’s complicated gasoline and pressurization system. The Starship’s higher stage will then be stacked on the Tremendous Heavy, and the mixed automobiles should bear a moist gown rehearsal.

It appears clear that SpaceX is refining its strategy to working with the Starship structure, as current checks, together with Tuesday’s, have ended with out obvious failures.

After finishing all of the technical coaching, SpaceX should additionally receive a launch license from the Federal Aviation Administration, which remains to be pending. Whereas it stays theoretically doable that Starship will try an orbital launch in December, it’s more and more possible that the take a look at flight will happen in early 2023.
