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.

Elon Musk’s Boring Co. Tunnel Vision Challenge ends with a surprise for Louisiana, Maryland and Dallas
The Boring Company stunned three cities today, awarding New Orleans, Baltimore, and Dallas free underground Loop tunnels.
Elon Musk’s The Boring Company (TBC) announced today that it is building free underground Loop tunnels in three American cities: New Orleans, Louisiana; Baltimore, Maryland; and Dallas, Texas. The company had promised one winner when it launched the Tunnel Vision Challenge in January. After receiving 487 submissions, it selected three, committing to fund and construct all of them pending a feasibility review, entirely at its own expense. For a company that has faced years of skepticism over the gap between its promises and its delivered projects, choosing to expand its commitment rather than narrow it is a notable shift in both scale and accountability.
All three projects will now enter a rigorous, fully funded diligence phase that includes meetings with elected officials, regulators, community and business leaders, geotechnical borings, and a complete investigation of subsurface utilities and infrastructure. TBC confirmed that all costs associated with this diligence process are 100% funded by the company. If all three projects pass feasibility, all three get built. If only one clears the bar, that one gets built. The company’s willingness to fund the due diligence regardless of outcome removes one of the most common early-stage barriers that kills promising infrastructure proposals before they leave a spreadsheet.
Beyond the three winners, TBC announced it will continue working with two additional entrants it found compelling enough to pursue independently: the Hendersonville Utility Tunnel in Hendersonville, Tennessee, and the Morgan’s Wonderland Tunnel in San Antonio, Texas, which would notably serve one of the nation’s premier theme parks built specifically for guests with special needs.
The challenge also coincides with TBC’s most active construction period to date. The company recently began drilling on the Music City Loop near the Tennessee State Capitol in Nashville, and in February it broke ground on a Loop in Dubai. Musk has long argued that the fundamental problem with urban infrastructure is cost and bureaucratic inertia, not engineering. “The key to solving traffic is making going 3D either up or down,” he said in 2018, a conviction now reflected in a company structure built to absorb the financial risk that typically stalls public projects for years.
Music City Loop could highlight The Boring Company’s real disruption
The Tunnel Vision Challenge’s most underappreciated element may be what it produced beyond three winners. Submissions came from individuals, companies, and governments across states including Alaska, Arkansas, Colorado, Kansas, Louisiana, Maryland, New York, and Texas, as well as from international entrants. Musk captured the underlying logic years ago when he said, “Traffic is driving me nuts. I’m going to build a tunnel boring machine and just start digging.” Today, three American cities are counting on exactly that.
Tunnel Vision Challenge results!
We’ve been overwhelmed with the amazing submissions…so we are announcing three winners!
The Thrilling Three are:
– NOLA Loop (New Orleans, LA)
– Ravens Loop (Baltimore, MD)
– University Hills Loop (Dallas, TX)What happens next? TBC and the… https://t.co/cY2ULftfiK

Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means
What truly distinguishes this installation from the hundreds of “V4” stalls already scattered across the network? Most existing V4 dispensers, rolled out since 2023, feature welcome upgrades like longer cables, built-in touchscreen displays, integrated credit-card readers for non-Tesla users, and improved ergonomics.
Tesla has launched its first “true” V4 Supercharger on the East Coast, and while that may be sort of confusing, here’s what we mean by that.
Tesla has opened its first true V4 Supercharging station on the East Coast in Kissimmee, Florida, just south of Orlando.
The eight-stall site, powered by an advanced 1.2 MW V4 power cabinet, is capable of delivering up to 500 kW, making it one of only four fully operational 500 kW-capable V4 stations in the United States.
Pricing is dynamic and competitive, as Tesla owners pay $0.40 per kWh during peak hours (8 a.m. to midnight), dropping to an attractive $0.20/kWh off-peak (midnight to 8 a.m.).
Non-Tesla EVs, which can now plug directly into the NACS ports thanks to the open standard, are charged a premium—$0.56/kWh peak and $0.28/kWh off-peak—reflecting Tesla’s strategy to monetize network access while rewarding its own customers.
What’s Makes This a “True” V4 Supercharger
What truly distinguishes this installation from the hundreds of “V4” stalls already scattered across the network? Most existing V4 dispensers, rolled out since 2023, feature welcome upgrades like longer cables, built-in touchscreen displays, integrated credit-card readers for non-Tesla users, and improved ergonomics.
However, nearly all of these have been paired with legacy V3 power cabinets. These hybrid setups, sometimes informally called V3.5, deliver charging curves virtually identical to standard V3 stations, typically topping out at 250-325 kW depending on the vehicle and site conditions.
In contrast, Kissimmee’s true V4 architecture incorporates next-generation 1.2 MW power cabinets. These support battery voltages up to 1,000 V (double the 500 V of V3 systems) and can push up to 500 kW per stall.

• Location: Kissimmee, Florida (near Orlando)
• 8 charging stalls
• Fees for Tesla owners: $0.40/kWh ($0.20/kWh off-peak)

One compact cabinet efficiently powers all eight stalls, slashing the physical footprint and reportedly keeping deployment costs under $40,000 per stall, far cheaper than earlier designs.
Right now, the primary beneficiary is the Cybertruck, which can achieve dramatically faster charging at low states of charge.
Everyday models like the Model 3 and Model Y see little immediate difference in peak speeds, but the hardware lays the groundwork for future vehicles with higher-voltage batteries.
Tesla launches faster Cybertruck charging at all V4 Superchargers
This milestone signals Tesla’s accelerating push toward a high-power, future-proof Supercharger network.
As true V4 sites multiply, charging times will shrink, grid efficiency will improve, and the entire EV ecosystem, Tesla and non-Tesla alike, will benefit from the infrastructure lead Tesla continues to expand. For drivers in central Florida, the Kissimmee station is more than just another charging stop; it’s a glimpse of the faster, smarter charging era that’s finally arriving.

Tesla reveals various improvements to the Semi in new piece with Jay Leno
Tesla Chief Designer Franz von Holzhausen and Semi Program Director Dan Priestley joined Leno in a 47-minute segment revealing all of the various things it did to make the Semi even better as it heads toward volume production this year.
Tesla has revealed the various improvements it has made to the Semi with its redesign, which was unveiled late last year, on a new episode of Jay Leno’s Garage.
Tesla Chief Designer Franz von Holzhausen and Semi Program Director Dan Priestley joined Leno in a 47-minute segment revealing all of the various things it did to make the Semi even better as it heads toward volume production this year.
Last year, Tesla revealed it had updated the Semi design to fit the bill of its aesthetic, which, on its other vehicles, includes things like lightbars and a sleeker and more aerodynamic design. The changes were not all to appease the eye, but the drivers who will use the Semi on a daily basis to haul goods regionally as the program gets off the ground running.
Weight Reduction
Priestley revealed almost immediately that Tesla was able to cut out about 1,000 pounds of weight from the Semi compared to the previous version.
This does several things, all of which are positive to the mission of a Class 8 truck, which is to haul goods and obtain more efficient travel to cut down on logistics costs.
Initially, this can increase payload capacity, which is often the biggest value driver for fleets that frequently hit gross vehicle weight limits. Tesla’s early Pilot Program members, like PepsiCo. and Frito-Lay, are large-scale companies. They will benefit from a decreased overall weight.
Lighter vehicles also require less energy to accelerate, climb hills, and maintain highway speeds. This new design has that advantage, and as Leno said in his first drive with the Semi as he hauled another unit behind, “I don’t feel like I’m pulling anything.”
Drag Coefficient
Franz said one of the goals of the Semi was to get the drag coefficient down below that of a Bugatti Veyron. This would increase efficiency tremendously, a major need with a large truck like a Semi.
Drag coefficient is extremely valuable when it comes to electric vehicles, because the displacement of air is incredibly important for range ratings.
Franz said aerodynamic efficiency has been improved by 7 percent compared to the last model. He says the coefficient is around 0.4.
New Features and Improvements
Priestley shed some additional light on the Semi and some of the improvements the company has made under the hood.
These include:
- Fully Electric Steering Assist
- Cybertruck actuators are being used for more strength
- Tesla included a 48-volt architecture
- Semi will utilize 4680 battery cells, which are designed to last 1 million miles
These changes come after Tesla rolled out the Semi to various companies for its Pilot Program, which yielded tremendous results. Due to the years it has been working with those companies, it knew what things it had to change and what it had to improve upon before selling the Semi openly.
Fleet Data
The fleet data Tesla has gathered from the Pilot Program has been one of the most widely discussed parts of the Semi program.
Franz and Priestley said that there are currently a few hundred Semi units in the real world, and Tesla has gathered 13.5 million miles. One of those units has traveled over 440,000 miles in the years it has been on the road.
Tesla Semi’s latest adoptee will likely encourage more of the same
Pilot Program members have reported an uptime of 95 percent, and Tesla’s maintenance and Service teams have kept things running:
“80% of breakdowns if you have one, are returned back to the customer in less than 24 hours, and half are back in less than 1 hour.”
Demand
Priestley says demand for the Semi has never been higher, and due to the recent political climate and the impact things have had on gas prices, Tesla has never received more inquiries for the Semi than it has recently.
Many companies will be surprised to hear that the Semi Pilot Program has been an overwhelming success. As Tesla begins to build out the infrastructure for the vehicle, it will only benefit the all-electric Class 8 trucks that keep things moving.
CEO Elon Musk said Tesla plans to start high-volume production this year. The company also plans to start deliveries this year.
