SpaceX inaugurates two new Starship engine test stands with a static fire
Barely four months after breaking ground, SpaceX has completed a dual-bay Starship engine test stand and inaugurated the new facility with a Raptor static fire.
That means that SpaceX’s McGregor, Texas test and development center now has more capacity to test individual Starship engines than the Merlin 1D and Merlin Vacuum engines that power the company’s workhorse Falcon 9 and Falcon Heavy rockets – and less than two and a half years after full-scale Raptor testing first began. SpaceX needs that capacity more than ever before as it shifts its focus from medium-altitude, three-engine Starship production and launches to true orbital test flights with six-engine ships and 29-engine Super Heavy boosters.
Every one of those 35 engines – all of which are expected to be expended after a single orbital test flight – will first need to be qualified for flight via static fire tests in McGregor. As of last month, SpaceX had four separate Raptor test facilities – two horizontal bays, one vertical stand, and a separate bay used for some kind of subcomponent testing. That left Starship in a similar boat as Falcon, which has relied on three vertical Merlin test bays for more than a decade.
As SpaceX found out, Falcon Heavy production – requiring 27 M1Ds and one MVAC – can almost completely swamp those three Merlin test stands for the better part of a month or two. Given that signs are pointing to every orbital Starship test flight requiring almost three-dozen new Raptors, the qualification testing situation will be even more challenging if SpaceX wants to continue the program’s rapid pace of development and more or less monthly launches.
Based on aerial photos taken by a NASASpaceflight L2 forum contributor and later published in a February 2021 article, groundbreaking began in the last week of January. Within two months, the bulk of the dual-bay stand’s structure and plumbing appeared to be in place. Within three months, everything appeared to be ready to go and a Raptor was present for apparent fit checks. Finally, on June 4th, the stand came to life for the first time with a brief 15-second Raptor static fire – likely more to verify the brand new facility’s readiness than to test Raptor itself.
SpaceX thus built two brand new test stands from a dirt lot to completion in ~18 weeks, expanding McGregor’s full-scale Raptor test capabilities by at least ~67% in one fell swoop. That means that if qualifying 35 Raptors might have previously taken 5-8 weeks, McGregor can now feasibly complete the same work in 3-5 weeks and probably continue some level of experimental testing at the same time. Now, SpaceX just has to mass-produce and qualify dozens of Raptor engines at a pace likely unprecedented even in its exceptionally productive engine production and testing history.
SpaceX has announced a new target date for the thirteenth test flight of Starship: Monday, July 20, with the launch window opening at 6:45 p.m ET/5:45 p.m. CT.
This is the first rescheduling attempt of Starship’s 13th test flight. It was set to launch last night, but SpaceX scrubbed the launch attempt.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.
To be confident of a good flight, 2 Raptors will be removed & replaced. Most probable launch timing is early next week.

SpaceX officially announced the new launch window this morning.
Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.
For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.
Ultimately, it will splash down in the Indian Ocean.
The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.
Elon Musk flew under the radar with his recent purchase of a $1 billion energy company, according to Federal Trade Commission (FTC) documents.
Transaction number 202612350 listed Tesla and SpaceX frontman Elon Musk as the acquiring party and CF APR Super Holdings LLC as the seller, with New APR Energy, LLC as the acquired entity. The deal, which closed without public announcement, came to light on May 14.

Analysts inferred the deal’s scale from minority stakeholder disclosures, including one report of a 5 percent interest sold for approximately $50.4 million. Fortress Investment Group had purchased APR’s assets in late 2024, rebranded the operation as New APR Energy, and subsequently transferred ownership to Musk.
APR Energy specializes in rapidly deployable power infrastructure. The company maintains one of the world’s largest fleets of mobile gas and diesel turbines, with more than 1.1 gigawatts of generation capacity. Its modular units, which are often trailer-mounted, enable turnkey installations ranging from 20 MW to over 500 MW.
APR provides full engineering, procurement, construction, operation, and maintenance services for behind-the-meter power plants, serving everything from data centers, utilities, and industrial clients.
The firm has expanded aggressively to meet surging demand, recently adding turbines and deploying over 100 MW for a major AI hyperscaler. Its solutions bridge critical gaps where grid interconnections face delays of two to five years, according to Yahoo.
The acquisition means something more for Musk. As he continues to expand projects in artificial intelligence, especially xAI, his AI venture, there is a greater need to supply energy-intensive supercomputing clusters, including the Colossus project, with what they need: reliable and high-capacity power.
Ownership of APR provides immediate access to flexible generation assets that can be deployed adjacent to data centers, reducing dependence on a strained infrastructure. It also complements Tesla’s energy storage business, so Musk will be able to pull from his own entities to address the rapid scaling demands of AI training and compute.
