SpaceX is already preparing for operational astronaut missions
While the world’s attention is focused on the return of orbital human spaceflight from US soil after a nearly decade long absence with the upcoming May 27th Crew Dragon Demo-2 mission, SpaceX is simultaneously preparing for the first Crew Dragon operational mission certified by NASA, dubbed Crew-1, slated to occur later this year.
On Friday, April 24th, SpaceX treated its Twitter followers to some rare imagery of static fire testing completed at the company’s development facility in McGregor, Texas. The company spotlighted a fresh-from-the-factory Falcon 9 booster and Falcon 9 second stage Merlin Vaccum (MVac) engine intended for the Crew-1 mission. Crew-1, the follow-up mission to May’s Demo-2 mission and SpaceX’s first operational human spaceflight mission for NASA, will propel a crew of three NASA astronauts and one JAXA astronaut in a Crew Dragon capsule to the International Space Station.
SpaceX also provided its followers with a view of the pristine second stage MVac engine of the Crew-1 mission before it was sent to Texas for testing. The one-hundredth production MVac engine is seen inside of SpaceX’s manufacturing facility located in Hawthorne, CA before being prepared for shipment. The second stage MVac engine is the only piece of Falcon 9 hardware that SpaceX does not actively recover and reuse, unlike the first-stage booster and protective payload fairing nosecone.

Part of the process
A static fire test is a typical occurrence before shipping the booster and second stage to Florida for payload integration and launch. The static fire process involves holding down the booster and igniting the engines to run for a full-duration firing. A similar test is also performed on with the second stage MVac engine. These test-fires are performed at the Mcgregor facility to proof the vehicle and check for any inconsistencies or off-nominal test readings that may occur before shipping to the vehicle to the launch site. Following the test-fire, the entire vehicle is inspected, cleaned, and prepared for shipment.
A test-fire in Mcgregor is not the last time the engines will be put through the paces before launch. Typically a week or so before the scheduled launch date, the Falcon 9 booster is transported to the launch pad. There, the booster is fully fueled with propellant while securely held to the launch mount. All nine Merlin-1D engines are once again ignited briefly (anywhere between 6 – 12 seconds) to test the propellant load process and collect engine-firing measurements such as temperature and pressure.
Certification before operation
Although the Crew-1 mission is tentatively on the books for later this year, SpaceX and the Crew Dragon capsule have yet to achieve NASA certification to begin operational missions to and from the International Space Station. The second orbital demonstration flight of the Crew Dragon capsule (Demo-2) will serve as the final end-to-end test of SpaceX’s crew transportation system.
However, SpaceX still faces a few obstacles before achieving a full go-ahead by NASA for the launch of Demo-2. As reported by SpaceNews.com NASA’s Aerospace Safety Advisory Panel (ASAP) met via teleconference on Thursday, April 23rd for a routine quarterly briefing. In that meeting, it was briefly discussed that there are still a few “technical items” that remain to be cleared by NASA before the launch of the Demo-2 mission.
Although not specified in the briefing – and likely to be followed up on during “part 2” of the ASAP meeting to be held in early May – those items likely refer to wrapping up the joint investigation of a recent in-flight engine failure of a Falcon 9 Merlin-1D engine and one more qualifying drop-test of the Crew Dragon Mark 3 parachutes. SpaceX, however, shows no plans letting formalities stop the preparation to support future astronaut missions.

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Elon Musk sends first warning to SpaceX short sellers
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.
The survival probability of firms who maintain a significant short position in SpaceX over time is very low
— Elon Musk (@elonmusk) July 17, 2026
Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.
