SpaceX’s first flightworthy Starship prototype has rolled to its South Texas launch pad just hours after it was welded together and is now preparing for several critical tests it must pass before it can be deemed ready for liftoff.

Fabricated and assembled with incredible speed at SpaceX’s growing Boca Chica, Texas Starship factory and test facilities, the vehicle SpaceX moved to the launch pad earlier today (Feb 25) is meant to become the first full-scale Starship prototype to take flight. Following in the footsteps of the Starship Mk1 prototype, deemed too shoddy to launch and pressurized to destruction in November 2019, the first serial build (SN01) of an improved line of Starship prototypes appears to have taken less than a month to go from first weld to the launch pad.

CEO Elon Musk took to Twitter earlier today to confirm the Starship SN01 tank section’s move to the launch pad, further noting that the tank assembly is now preparing for Raptor engine installation ahead of a static fire test. According to NASASpaceflight.com, SpaceX wants to complete that static fire and launch Starship SN01 as early as next month – a seemingly improbable target that just got much more likely with the rocket’s tank section already at the launch pad. Most importantly, however, the speed with which SpaceX has been able to assemble and prepare Starship SN01 suggests that even if things go wrong or plans change, another completed prototype could be ready to head to the pad just a few weeks from now.

On February 25th, SpaceX CEO Elon Musk posted a screenshot taken from a livestream created by SPadre earlier that day, noting that Starship will soon have engines installed in preparation for a critical static fire test.

Under the cover of an incredibly thick fog bank, Starship SN01 was lifted onto a Roll Lift transporter and carefully moved from its factory facilities to SpaceX’s Boca Chica launch pad at 4:30 am PST. Around 7:30 am PST, the giant rocket tank was lifted onto the pad’s Starship mount and technicians have been working to connect SN01 to the ground systems ever since.

Built out of stainless steel, Starship SN01’s tank section – referring to the combined liquid oxygen tank, liquid methane tank, and engine section – stands about 30m (100 ft) tall and likely weighs at least 30-45 metric tons (~70,000-100,000 lb) as it stands. While SN01 is clearly missing its pointed nose section (‘nosecone’) and flaps, among other parts, its tank section has been moved to the launch pad to perform tests that don’t involve the ship’s aerodynamic properties.

Starship Mk1 – SpaceX’s first attempt at a full-scale prototype – was fabricated and stacked piece by piece over the course of nine months before its tank section – looking almost identical to SN01 – first rolled to SpaceX’s launch pad on October 30th, 2019. Three weeks later, it was intentionally pressurized until it popped after engineers concluded that its production quality was too low for a flight test attempt to be worth the effort. On the other hand, the first of Starship SN01’s steel rings was definitively completed in the last week of January 2020, quite possibly just four weeks before the completed tank section was rolled to the same launch pad.

With that kind of speed, it’s no surprise that Musk says SpaceX will start stacking Starship SN02’s tank section this week. Intriguingly, Musk also stated that Starship SN02 would have three Raptors installed, avoiding the original question’s focus (SN01). As such, it appears that Starship SN01 may only have one Raptor installed for a static fire test and would be unlikely to ever fly if that were the case. It’s possible that after two highly successful (and explosive) pressure tests of smaller Starship test tanks that were completed last month, SpaceX still wants to perform a similar pressure test with a fully-integrated, full-scale Starship tank section to confirm that the smaller tank results carry over.

Whether SN01 is still destined for flight, it’s safe to say that Starship SN01 tank testing could begin in a matter of days — SpaceX currently has early-morning roadblocks indicative of such testing scheduled from February 29th to March 2nd. SpaceX is likely to kick off by filling SN01 with water to check its tanks for leaks, followed by liquid nitrogen – chemically neutral but still incredibly cold. After that, SN01 would likely graduate to Raptor engine installation and a wet dress rehearsal (WDR) with liquid oxygen and methane before moving on to a static fire attempt, if all goes well.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day

SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.

SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.

That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.

The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.

On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.

The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.

NASA taps SpaceX to launch the telescope that could unlock new worlds

If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.

The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.

Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think

Published

Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.

The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:

“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”

Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”

Priestley also highlighted a practical payoff of the indirect design:

“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”

This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.

The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.

Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.

For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode

Published

Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.

For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.

However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.

“Because this event can only be held outdoors…”

Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”

With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.

FAA Airspace Restriction

The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.

Elon Admits High Winds

“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.

All signs are pointing toward an aerial demonstration for the Roadster.
