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.

SpaceX launches Ax-4 mission to the ISS with international crew
The SpaceX Falcon 9 launched Axiom’s Ax-4 mission to ISS. Ax-4 crew will conduct 60+ science experiments during a 14-day stay on the ISS.
SpaceX launched the Falcon 9 rocket kickstarting Axiom Space’s Ax-4 mission to the International Space Station (ISS). Axiom’s Ax-4 mission is led by a historic international crew and lifted off from Kennedy Space Center’s Launch Complex 39A at 2:31 a.m. ET on June 25, 2025.
The Ax-4 crew is set to dock with the ISS around 7 a.m. ET on Thursday, June 26, 2025. Axiom Space, a Houston-based commercial space company, coordinated the mission with SpaceX for transportation and NASA for ISS access, with support from the European Space Agency and the astronauts’ governments.
The Ax-4 mission marks a milestone in global space collaboration. The Ax-4 crew, commanded by U.S. astronaut Peggy Whitson, includes Shubhanshu Shukla from India as the pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary.
“The trip marks the return to human spaceflight for those countries — their first government-sponsored flights in more than 40 years,” Axiom noted.
Shukla’s participation aligns with India’s Gaganyaan program planned for 2027. He is the first Indian astronaut to visit the ISS since Rakesh Sharma in 1984.
Axiom’s Ax-4 mission marks SpaceX’s 18th human spaceflight. The mission employs a Crew Dragon capsule atop a Falcon 9 rocket, designed with a launch escape system and “two-fault tolerant” for enhanced safety. The Axiom mission faced a few delays due to weather, a Falcon 9 leak, and an ISS Zvezda module leak investigation by NASA and Roscosmos before the recent successful launch.
As the crew prepares to execute its scientific objectives, SpaceX’s Ax-4 mission paves the way for a new era of inclusive space research, inspiring future generations and solidifying collaborative ties in the cosmos. During the Ax-4 crew’s 14-day stay in the ISS, the astronauts will conduct nearly 60 experiments.
“We’ll be conducting research that spans biology, material, and physical sciences as well as technology demonstrations,” said Whitson. “We’ll also be engaging with students around the world, sharing our experience and inspiring the next generation of explorers.”
SpaceX’s Ax-4 mission highlights Axiom’s role in advancing commercial spaceflight and fostering international partnerships. The mission strengthens global space exploration efforts by enabling historic spaceflight returns for India, Poland, and Hungary.
