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 plein air in a fairly unorthodox fashion – and test whether they are functional pressure vessels without risking immediate and total destruction. If successful, SpaceX will proceed into Raptor integration and integrated static-fire tests before preparing for tethered hover tests, perhaps as early as later this month.

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.

60 hours later, Musk was clearly not wrong.

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.

SpaceX accepted delivery of multiple truckloads of liquid nitrogen on March 10th, likely to support early tank loading tests to verify structural integrity and check for leaks. (NASASpaceflight – bocachicagal)

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.

The Philippines’ Department of Information and Communications Technology (DICT) is using Starlink to provide connectivity in the municipality of Masbate, which was affected by Severe Tropical Storm Opong (international name Bualoi). 

The Severe Tropical Storm battered the province, leaving communications networks in the area in shambles.

Starlink units enhance connectivity

DICT Secretary Henry Aguda visited the province to assess internet and communications infrastructure and deliver 10 additional Starlink satellite units, according to the Philippine News Agency. The is move aimed at strengthening emergency response and restore digital access to the area.

Aguda met with Masbate Governor Richard Kho during his visit and joined telecommunications representatives in inspecting provincial offices, free charging stations, and Wi-Fi connectivity sites for residents. 

According to DICT officer-in-charge Rachel Ann Grabador, three Starlink units, 10 routers, and a 2kW solar-powered station have already been deployed in the province following the typhoon. The units have been installed at key facilities such as Masbate Airport’s communications tower and the Masbate Provincial Hospital’s administrative office.

Game-changing technology

Thanks to its global coverage and its capability to provide high-speed internet connectivity even in remote areas, Starlink has become the best communications solution that can be deployed in the aftermath of natural disasters. Its low-cost kits, which are capable of of providing fast internet speeds, are also portable, making them easy to deploy in areas that are damaged by natural disasters.

As noted in a Space.com report, there are currently 8,475 Starlink satellites in orbit, of which 8,460 are working, as of September 25, 2025. Initially, SpaceX had filed documents with International regulators to place about 4,000 Starlink satellites in Low Earth Orbit. Over time, however, the number of planned Starlink satellites has grown, with SpaceX aiming to launch as many as 42,000 Starlink satellites to fully connect the globe.

SpaceX shares targets and tentative launch date for Starship Flight 11

As with all SpaceX tests, the estimated timeline for Starship Flight 11 remains subject to change based on conditions and readiness.

SpaceX is targeting Monday, October 13, for the eleventh test flight of its Starship launch system. The launch window is expected to open at 6:15 p.m. CT. 

Similar to past Starship missions, a live webcast will begin about 30 minutes before launch on SpaceX’s website, X account, and X TV app. As with all SpaceX tests, the estimated timeline for Starship Flight 11 remains subject to change based on conditions and readiness.

Super Heavy booster landing test

The upcoming mission will build on the data gathered from Starship’s tenth test flight, focusing on booster performance and upper-stage capabilities. The Super Heavy booster, previously flown on Flight 8, will launch with 24 flight-proven Raptor engines, according to SpaceX in a blog post on its official website. Its primary objective is to validate a new landing burn engine configuration designed for the next generation of Super Heavy.

Instead of returning to Starbase, the Super Heavy booster will follow a trajectory toward the Gulf of America. During descent, it will ignite 13 engines before transitioning to a five-engine divert phase and then completing the landing burn with three central engines, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America.

Starship upper-stage experiments

The Starship upper stage for Flight 11 will carry out a series of in-space demonstrations, including the deployment of eight Starlink simulators that are comparable in size to next-generation Starlink satellites. These payloads will reenter and burn up during descent. A planned Raptor engine relight in orbit will also provide valuable test data.

To evaluate the upper stage’s resilience during reentry, SpaceX engineers have intentionally removed heat shield tiles from select areas to stress-test Starship’s thermal protection system. The vehicle will attempt new maneuvers during descent, including a banking profile and subsonic guidance algorithms intended to simulate future return-to-launch-site missions. The upper stage will ultimately target a splashdown in the Indian Ocean.

SpaceX has already posted a link to the livestream for Starship Flight 11:

Astra CEO shades SpaceX over employee workload and Starbase

Elon Musk once stated that no one ever changed the world working just 40 hours a week. This was something that is openly known among his companies. They have the potential to change the world, but they require a lot of hours.

SpaceX’s working environment was recently criticized by Chris Kemp, the chief executive officer of Astra. During some remarks at the Berkeley Space Symposium 2025 earlier this month, Kemp shared some sharp remarks about the Elon Musk-led private space enterprise.

SpaceX working conditions and Starbase

As noted in a report from Ars Technica, Kemp discussed a variety of topics during his talk. These included Astra’s successes and failures, as well as his thoughts on other players in the spaceflight industry. To be fair to Kemp, he practically shaded every major rival, calling Firefly’s engine “garbage,” dubbing Blue Origin as slow, and stating that Rocket Lab’s Electron rocket is “too small.”

SpaceX also received some colorful words from the Astra CEO. According to Kemp, SpaceX is leading the way in the spaceflight industry and Elon Musk is admirable in the way that he is willing to fail in order to move quickly. He did, however, highlight that Astra offers a significantly better working environment than SpaceX.

“It’s more fun than SpaceX, because we’re not on the border of Mexico where they’ll chop your head off if you accidentally take a left turn. And you don’t have to live in a trailer. And we don’t make you work six and a half days a week, 12 hours a day. It’s appreciated if you do, but not required,” Kemp said.

Elon Musk’s demands

It is known that Elon Musk demands quite a lot from his employees. However, it is also known that Musk-led companies move very fast and, in more ways than one, they have accomplished world-changing feats. Tesla, for example, has practically ushered in the era of the modern electric vehicle, and SpaceX has made space attainable through its reusable rockets. With this in mind, employees at Musk’s companies, and this of course includes SpaceX, are likely proud of their long work hours. 

No one could probably go to Mars in this lifetime with a team that really works just 40 hours a week, after all.
