Over the last two or so weeks, SpaceX engineers and technicians have continued to make progress on the company’s first full-scale Starship prototype, intended to support experimental suborbital hop tests as early as March or April.

That work reached a peak on March 8th when the massive Starhopper was transported from build site to launch pad on a brand new transporter that was delivered and assembled barely 48 hours prior. Ahead of the suborbital prototype’s move, work has been ongoing to construct a replacement fairing for the partial-fidelity vehicle, although there is a chance that the new BFR-related stainless steel sections being assembled could be the start of the first orbital Starship prototype.

Required after improper planning destroyed Starship’s original nosecone (or fairing) when it broke free from its insufficient moorings during high coastal winds, the replacement has sprouted from sheets of metal into a far more substantial structure in barely two weeks. Designed as two integral parts of a suborbital Starship prototype, the upper section (i.e. fairing, nosecone, etc.) is predominately a passive aerodynamic structure with no major active functions, thankfully meaning that the first article’s accidental destruction was a relatively minor loss.

In fact, it’s entirely possible that the fairing’s demise has had a minimal impact on the commencement of hop tests, and may have even been a net-good for the program given some visible differences between Starship fairings #1 and #2. Despite the fact that the first fairing was destroyed in late January and a comment from CEO Elon Musk indicating that it would trigger a delay of a few weeks, SpaceX did not begin to assemble its replacement until February 21st, a full month later. Over the course of those 30 or so days, the company’s propulsion team simultaneously began hot-fire tests of the first full-scale Raptor engine, ramped thrust and chamber pressure from roughly 40 to 100 percent, and ultimately pushed the engine to the point of damage around the second week of February.

Work on the primary structure of the Starship prototype also proceeded apace, fleshing out the brute-force steel vehicle with the beginnings of serious avionics and plumbing and more or less completing the structure of its liquid oxygen and methane propellant tanks. SpaceX workers also rapidly expanded and built-out Starship’s prospective hop test launch pad just a few thousand feet distant, installing tank farms, piping, water deluge hardware, and building an actual concrete ‘pad’ with umbilical connection ports and attachment points for the ship’s three fin-legs.

Welding and assembly of the replacement nosecone began around February 21st, rapidly growing from a few sheets of steel to a nearly-complete barrel section measuring about 9m tall and 9m in diameter (30ft x 30ft). Intriguingly, the new fairing appears to be a significant departure from the structural composition of its predecessor, utilizing far thicker sheets of stainless steel joined by uninterrupted width and lengthwise welds. Compared to the first fairing’s dependence on extremely thin (nearly foil-like) steel sheets and a separate internal framework of metal bars, Starship fairing V2 appears to be easily capable of standing under its own weight and then some. While largely passive, it’s likely that once the structure is complete, some level of additional avionics (and perhaps cold or hot-gas maneuvering thrusters) will be installed inside.

U-Crawl

Keeping in the practice of dramatically lowering costs by prioritizing consumer off-the-shelf (COTS) hardware solutions wherever possible, SpaceX has purchased or leased a quartet of (likely used) crawlers for the purpose of transporting Starship between the company’s South Texas build, launch, and landing sites. Built by a European conglomerate known TII Group and owned by US-based Roll Group, SpaceX’s four crawlers – coupled to form a duo of larger crawlers – should be more than capable of transporting anywhere from 500t to 1000t or more, easily supporting Starhopper and/or Starships and Super Heavy boosters.

Rather than spending huge amounts of money to develop or contract out a custom-designed crawler or transporter solution for BFR, SpaceX appears to have simply purchased off-the-shelf hardware and affixed them with heavy steel structures capable of securing and supporting Starhopper during transport. Within 24 hours of the crawler arrivals, those beams were installed and the transporter had been moved underneath Starhopper and attached to it before quite literally jacking the massive ship off the ground, allowing technicians to weld additional structures to the tips of its three legs.

Last but not least…

Perhaps most curious of all, Starhopper’s replacement fairing was recently joined by the start of work on a separate barrel section that appears to be nearly identical. Assuming the presumed fairing is, in fact, a fairing-to-be, the combined height of the two barrel sections would already make it significantly taller than the original nosecone, and the beginning of the conical taper has yet to appear on either assembly. This could generally mean one of two things. First, the new fairing could make Starhopper much taller than its short-lived predecessor. Second, SpaceX could be planning to begin (or even complete) hop tests without a fairing, in which case the presumed fairing and its slightly younger twin could actually be the beginning of a higher-fidelity Starhopper or even the orbital Starship prototype hinted at by Musk earlier this year.

While far less likely than the first option, the latter alternative is further supported by the fact that visible work has begun on some sort of tapered or curved steel complements to the new sections in work. While they certainly could be the beginning of the fairing’s tapered cone, the latest segments only loosely resemble the start of a gradual curve. Instead, they look similar to the steel segments of several giant tank domes that were assembled, welded, and installed inside Starhopper last month.

On March 8th, SpaceX began the transport of its first full-scale Starship prototype at the same time as CEO Elon Musk indicated that the first flightworthy Raptor(s) would be delivered to South Texas and installed on the hop test article as early as next week (March 11-17). It’s now looking increasingly likely that any replacement fairing that may or may not be under construction might not be ready for installation on Starhopper before SpaceX begins integrated static-fire tests and maybe even low-altitude tethered hop tests.

“SpaceX will conduct checkouts of the newly installed ground systems and perform a short static fire test in the days ahead,” he said. “Although the prototype is designed to perform sub-orbital flights, or hops, powered by the SpaceX Raptor engine, the vehicle will be tethered during initial testing and hops will not be visible from offsite. SpaceX will establish a safety zone perimeter in coordination with local enforcement and signage will be in place to alert the community prior to the testing.” – James Gleeson, March 8th, SpaceX

Elon Musk reveals SpaceX’s target for Starship’s 10th launch

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.

Crew Dragon Endeavour returns

Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.

“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.

For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.

The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.

The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.

Tight launch timing

Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.

“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

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.
