SpaceX’s orbital Starship launch debut could still happen this year
Despite the spectacular demise of a full-scale prototype just days ago, a senior SpaceX engineer and executive believes that Starship could still be ready for its first orbital launch attempt before the end of the year.
Even if the first launch attempt fails, that milestone – if realized – would be one of the single biggest upsets in the history of spaceflight, proving that Saturn V-scale orbital-class rockets can likely be built in spartan facilities with common materials for pennies on the dollar. Much like Falcon 1 suffered three launch failures before successfully reaching orbit, there’s a strong chance that Starship’s first shot at orbit will fall short, although each full-up launch failure would likely cost substantially more than the current prototypes being routinely tested to destruction in South Texas.
Most recently, what CEO Elon Musk later described as a “a minor test of a quick disconnect” went wrong in a spectacular fashion, causing a major liquid methane leak that subsequently ignited and created a massive explosion. Although Starship SN4 did technically complete its fifth Raptor engine static fire test just a minute or so prior, the ship and its immediate surroundings were obliterated by the violent explosion, leaving little more than steel shrapnel and the broken husk of a launch mount behind. It’s in this context that one of SpaceX’s most levelheaded, expert executives believes that an orbital launch could still happen this year.
While Starship SN4’s demise and the continued possibility of the ship’s orbital launch debut occurring less than seven months from now may seem at odds with each other, that’s actually just a side effect of the approach SpaceX has always taken when developing brand new rockets and spacecraft. Following the lead of the scrappy teams that used the exact same methods to design, test, and fly the massive Saturn rockets that took humans to the Moon, SpaceX has always preferred to learn by doing.
Inevitably, testing minimum viable products to their limits will lead to failures, but those failures are actually extremely valuable so long as they are extensively analyzed and learned from. That’s exactly what SpaceX has been doing for the last six or so months with full-scale Starship prototypes: building, testing, failing, and improving in an unending cycle. Built slowly with inferior methods, Starship Mk1 almost immediately during its first pressure test in November 2019. SpaceX took that failure, extracted all the insight it could, and dramatically improved its production methods before completing Starship SN1 barely three months later.
Prior to SN1, SpaceX built and tested two stout test tanks to failure, ultimately achieving pressures of ~8.5 bar – sufficient for reliable human spaceflight – with the second tank on January 30th, 2020. On February 28th, Starship SN1 was unfortunately destroyed by a faulty ‘thrust puck’ (Raptor engine mount). Just 10 days later, SpaceX successfully tested a third ad-hoc test tank, proving that it had already rectified the engine section design flaw. Hardware isn’t always the only problem, however, and Starship SN3 was destroyed by human operator error during a cryogenic proof test on April 3rd.
Starship SN4 was completed and moved to the launch pad less than a month later and began testing just a few days after that, quickly racking up milestones as it became the first full-scale prototype to pass cryogenic proof testing, perform a wet dress rehearsal (WDR) with real propellant, fire up a Raptor engine, and complete a more ambitious cryogenic pressure test. Prior to the ground systems fuel leak that killed it, SN4 was possibly just days away from attempting the inaugural flight of a full-scale Starship prototype.
With Starship SN4 now steel confetti, Starship SN5 – effectively complete – will likely take over where its predecessor left off, heading to the launch pad within the next week or so before attempting a cryogenic pressure test and Raptor static fire to clear it for flight. Per Koenigsmann, that flight debut could come just a few weeks from now – likely before the end of June if replacement ground equipment can be quickly completed. If Starship SN5 survives that hop debut, it may ultimately be upgraded with a nosecone, flaps, and two additional Raptor engines to perform a dramatic 20 km (~12 mi) flight, capped with a supersonic skydiver-style reentry and landing test.
Once that capability has been successfully demonstrated, Super Heavy development and orbital Starship operation and reentry are the next critical hurdles. If Koenigsmann is correct, it’s safe to say that the first fully heat-shielded Starships and the beginnings of the first one or several Super Heavy booster prototypes will begin to appear in South Texas within the next few months.

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.
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.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
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.
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.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

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.
