SpaceX begins static Starhopper tests as Raptor engine arrives on schedule
SpaceX has officially begun static ground testing of Starhopper, a full-scale pathfinder Starship prototype meant to support an early series of Raptor-powered hop tests at SpaceX’s South Texas launch site. Simultaneously, the second completed Raptor engine arrived at the site on Monday, March 11th, confirming CEO Elon Musk’s March 8th tweets about the delivery.
While reasonably routine for any rocket test program, the first tanking test of Starhopper effectively marks the first time that SpaceX has begun tests with a more or less fully integrated Starship (previously BFS). Likely performed with liquid nitrogen instead of liquid oxygen/methane, the first few tanking tests will be used to determine the quality of the prototype’s stainless steel tanks – built en
In November 2016, SpaceX began propellant-loading tests of its first finished full-scale Starship (then Big Falcon Spaceship) hardware, a massive carbon composite liquid oxygen tank stretching 12 m (~40 ft) in diameter. Over the course of 2017, SpaceX transitioned from liquid nitrogen to liquid oxygen and ultimately conducted one final burst-test in which the composite tank was pressurized until it exploded, ending full-scale BFR composite testing with a bang. Within 6-12 months, Musk had come to the conclusion that a stainless steel BFR would ultimately be a superior path forward for the rocket and spaceship and attempted (apparently successfully) to get his team of R&D engineers on board with such a radical change so late in the development phase.
Despite the fact that that radical design departure may have occurred as few as 6-8 months ago, SpaceX engineers and technicians have accomplished an extremely rapid development program that will – in part – culminate in the hopefully successful hop testing of Starhopper, the first Starship prototype. While more of a rough testbed than an actual representation of the hardware and structures that will be required for a reusable orbital-class Starship, Starhopper has at least acted as a crash course (either technically or organizationally) on fabricating and assembling stainless steel aerospace structures, a material largely foreign to SpaceX flight hardware prior to late 2018.
Although the early vehicle was less than encouraging, as was the demise of its nosecone as a consequence of improper planning and/or bad workmanship, Starhopper as it now stands might actually be flightworthy in the context of suborbital, subsonic hop tests. Powered by the same or similar Raptors that would power orbital prototypes, Starhopper’s hop tests would optimally provide a wealth of experience and engineering data for both building 9 meter/30 foot-diameter stainless steel rocket sections and operating full-scale Raptor engine(s) in actual flight configurations. Extensive testing with Raptor will help to ensure that the fit and finish of the new engine’s flight-grade avionics and hardware are up to the challenge of safe, reliable, and gentle operations for a nominally crew-rated launch vehicle and spacecraft.
Around two days after Starhopper was briskly transported from its build site to SpaceX’s brand new launch facility, local Twitter account @SPadre (short for South Padre Island) posted a video of tanking test that occurred on March 11th, capturing the sound of venting as the liquid involved turned to gas inside its propellant tank(s). The fact alone that the person behind the camera was allowed to be where they were during the test all but guarantees that this first test was performed with an inert liquid, most likely liquid nitrogen given a massive delivery that occurred the day before (March 10th). In no conceivable world would SpaceX or local law enforcement willingly allow for Starhopper to be loaded – for the first time ever – with even a partial load of liquid methane or liquid oxygen with bystanders barely a few hundred feet distant.

When SpaceX gets to the point that they are confident enough in the structural integrity of Starhopper to begin wet dress rehearsals and tests with actual propellant, it’s a safe bet that the company will cooperate with local law enforcement to block off the lone access road to a distance of at least 1-2 miles, if not more. It’s unclear if local homeowners and residents will be forced to vacate the adjacent Boca Chica Village during testing, but chances are good that nobody will be within several thousand feet of Starhopper when those propellant loading tests begin, let alone actual static fire activity once Raptor(s) are installed.
According to an official SpaceX statement on the progress, propellant load tests and static fires could begin “in the days ahead”, although the spokesperson was under the impression that those tests – as well as initial hop tests – “[would] not be visible from offsite”. Unless SpaceX plans to draw a keep-out zone with a radius of multiple miles, interested observers will almost certainly be able to get close enough to at least catch a glimpse of Starhopper, but the statement still offers an idea of just how focused the company will be on safety during these early tests.

Roughly 8.5 minutes after liftoff, the Falcon 9’s first stage touched down on the drone ship Of Course I Still Love You in the Pacific Ocean. This marked the booster’s 29th flight, which is approaching SpaceX’s reuse record of 31 missions.
This latest mission adds to SpaceX’s impressive 138 Falcon 9 launches in 2025, 99 of which were dedicated to Starlink, according to Space.com. The company’s focus on reusing boosters has enabled this breakneck pace, with multiple launches each week supporting both Starlink’s expansion and external customers.
Starlink’s network continues massive global expansion
Starlink remains the largest active satellite constellation in history, with more than 10,000 satellites launched, nearly 8,800 of which are currently active. SpaceX recently achieved Starlink’s 10,000-satellite milestone. With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.
Starlink, which provides high-speed, low-latency internet connectivity even to the world’s most remote areas, has been proven to be life-changing technology for people across the globe. The service is currently operational in about 150 countries, and it currently has over 5 million subscribers worldwide. From this number, 2.7 million joined over the past year.

SpaceX checks off 49 lunar lander milestones in push toward Artemis III
SpaceX has revealed that it has completed 49 major milestones for NASA’s Human Landing System (HLS) program, marking significant progress in the development of the Starship lunar lander that will deliver astronauts to the Moon.
The updates were detailed in SpaceX’s new blog post To the Moon and Beyond, which was recently posted on the private space company’s official website.
As noted by SpaceX, the 49 milestones that were completed by its HLS team were “tied to developing the subsystems, infrastructure, and operations” needed to safely land humans back into the lunar surface. SpaceX noted that it has only received funding on contractual milestones that have been successfully completed, the vast majority of which have been achieved on time or ahead of schedule.
Following are highlights of SpaceX’s completed milestones, as per the company’s post.
For the first time in our existence, we possess the means, technology, and, for the moment, the will to establish a permanent human presence beyond Earth. Starship is designed to make this future a reality → https://t.co/dGAZiB4rr3 pic.twitter.com/WsTg44G3oz — SpaceX (@SpaceX) October 30, 2025

SpaceX sets the record straight on Jim Bridenstine and Artemis 3
SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
SpaceX pushed back firmly against former NASA administrator Jim Bridenstine after he questioned the agency’s reliance on Starship for the Artemis 3 Moon mission.
In a detailed thread on X, SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
Bridenstine’s comments on Starship and Artemis 3
Bridenstine and fellow former NASA chief Charlie Bolden noted during a recent symposium that NASA’s current Artemis strategy is approaching zero chance of beating China to the Moon. Bridenstine expressed skepticism that NASA’s current architecture, which is expected to use Starship to transport astronauts to and from the lunar surface, could succeed in time.
“Starship is a tremendously important vehicle for the future,” Bridenstine said, as per Space News. “It’s going to deliver large mass to low Earth orbit for a long time, and it’s going to drive down costs and increase access. But if you need a moon lander, it’s going to take time.”
SpaceX responds to the former NASA administrator’s comments
In a series of posts on X, SpaceX noted that while the company is very thankful to the former NASA administrator for helping create the Artemis Program, his comments about Starship might not necessarily be coming from a place of objectivity.
SpaceX’s comments are as follows: “Like many Americans, we are thankful for Mr. Bridenstine’s service leading NASA at one point. He deserves credit for spearheading the creation of the Artemis Program. After departing NASA, he created a lobbying firm called the Artemis Group, representing a host of aerospace companies vying for NASA business.
“Mr. Bridenstine’s current campaign against Starship is either misguided or intentionally misleading. SpaceX was selected to design and develop a Human Landing System for Artemis along with Blue Origin and Dynetics during Mr. Bridenstine’s tenure as NASA Administrator.
“Starship was then selected by NASA for the Artemis III mission through fair and open competition after being identified as the best and lowest risk technical option – and the lowest price by a wide margin – by the civil servant team appointed to lead the agency’s exploration mission by Mr. Bridenstine himself.
“The decision to select Starship was confirmed repeatedly following protest and litigation from the companies not selected which delayed the start of work on the contract for many months. Mr. Bridenstine’s recent musings promoting a new landing system – going so far as to invoke the Defense Production Act – are being misreported as though they were the unbiased thoughts of a former NASA Administrator. They are not.
“To be clear, he is a paid lobbyist. He is representing his clients’ interests, and his comments should be seen for what they are – a paid lobbyist’s effort to secure billions more in government funding for his clients who are already years late and billions of dollars overbudget,” SpaceX wrote.
