Elon Musk pegs SpaceX BFR program at $5B as NASA’s rocket booster nears $5B in cost overruns
At the same time as NASA’s overrun-stricken Space Launch System (SLS) continues to limp towards its continuously delayed launch debut, now tentatively expected no earlier than (NET) 2021, SpaceX is forging ahead with the development of an equivalently capable launch vehicle known as BFR, comprised of a spaceship (BFS) and booster (BFB).
During a September 17th update to the next-gen SpaceX rocket’s steady progress, CEO Elon Musk offered a rough cost estimate of $5B to complete its development – no less than $2B and no more than $10B. According to NASA’s Office of the Inspector General (OIG), Boeing – primary contractor for NASA’s SLS “Core Stage” or booster – is all but guaranteed to burn through a minimum of $8.9B between 2012 and the rocket’s tentative 2021 launch debut.
NASA is finally (officially) acknowledging that EM-1, the maiden launch of SLS, will slip until at least June 2020. Sources tell us to expect another slip to 2021, official or not.https://t.co/CYf9SqbhBY

Originally contracted in 2014 to complete SLS booster development, production, and preparation by 2018 at a cost of $4.2B, Boeing has overrun its budget by a bit less than 50% (up to $6.2B) and overshot its scheduled launch debut by more than 2.5 years. Per an October 10th audit of the SLS booster program, NASA OIG has reasonably concluded that Boeing will pass that $6.2B expenditure estimate – meant to last until 2021 – in December 2018, meaning that at least an additional $2.7B will be required from NASA between now and 2021 if SLS is to have a chance at launching that year.
In other words, compared to Boeing’s first serious 2014 contract for the SLS Core Stages – $4.2B to complete Core Stages 1 and 2 and launch EM-1 in Nov. 2017 – the company will ultimately end up 215% over-budget ($4.2B to $8.9B) and ~40 months behind schedule (42 months to 80+ months from contract award to completion). Meanwhile, as OIG notes, NASA has continued to give Boeing impossibly effusive and glowing performance reviews to the tune of $323 million in “award fees”, with grades that would – under the contracting book NASA itself wrote – imply that Boeing SLS Core Stage work has been reliably under budget and ahead of schedule (it’s not).

The “Satisfactory” Stuff
In reality, Boeing has not once been under budget or ahead of schedule during any of 6+ NASA performance reviews.
“Boeing should have received a “satisfactory” rating for [two review periods]; a “good” rating for [one review period]; and an “unsatisfactory” rating (no award fee) for [the 2017 review period].”
Instead, NASA has given Boeing three “Very Good” (nearly perfect) reviews and three “Excellent” (perfect) reviews over the last 6 years, ultimately dispersing $323M of pure-profit “award fees” thanks to those grades, while the OIG firmly disputes Boing’s worthiness for at least $65M of that sum.
It is pretty pathetic when the only response that @BoeingSpace can muster via @BKingDC at its #politicospace PR effort in response to a damning @NASA_SLS report by @NASAOIG is to dump on the Saturn V – a rocket that actually flew – and worked – half a century ago. https://t.co/daN91bzwpC

Boeing – recently brought to light as the likely source of a spate of egregiously counterfactual op-eds published with the intention of dirtying SpaceX’s image – also took it upon itself to sponsor what could be described as responses to NASA OIG’s scathing October 10th SLS audit. Hilariously, a Politico newsletter sponsored by Boeing managed to explicitly demean and belittle the Apollo-era Saturn V rocket as a “rickety metal bucket built with 1960s technology”, of which Boeing was the core stage’s prime contractor.
At the same time, that newsletter described SLS as a rocket that will be “light years ahead of thespacecraft [sic] that NASA astronauts used to get to the moon 50 years ago.” At present, the only clear way SLS is or will be “light years” ahead – as much a measure of time as it is of distance – of Saturn V is by continuing the rocket’s trend of endless delays. Perhaps NASA astronomers will soon be able to judge exactly how many “light years ahead” SLS is by measuring the program’s redshift or blueshift with one of several ground- and space-based telescopes.
Ultimately, this is a particularly effective bit of self-mockery in the context of rationale lately used by Boeing and NASA to shrug off the jaw-dropping Core Stage contract’s underperformance, missteps, schedule slips, and budget overruns, namely that building big, complex rockets is hard. NASA and Boeing, neither of which have any meaningful experience building big, complex rockets – aside from Saturn IB, Saturn V, and the Space Shuttle – thus should be given a break for reliably and dramatically underestimating the difficulties of doing so in the 21st century.
One of the most breathtaking things about the new SLS report is the response by NASA's Gerstenmaier. Essentially, he says, this a is a big, complex rocket. And it's hard to build this stuff.https://t.co/ou8SFhji6a

Simultaneously, Boeing and NASA still continue to act as if they are the foremost global experts of building extremely large rockets and continue to throw pile upon pile of taxpayer billions at overpromised attempts to prove as much. It’s no more than a masochistic dream to imagine what could have been or might be if NASA instead redirected those billions towards US aerospace companies with track records of success through fixed-cost contracts or straight-up private funding (SpaceX and Blue Origin, primarily), but it’s often hard not to at least think about the possibilities.

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.
