Update: SpaceX has successfully resolved a handful of minor thermal control issues facing the brand new Crew Dragon capsule currently ferrying four astronauts in low Earth orbit (LEO).

As previously noted, shortly after the spacecraft reached orbit, two redundant thermal control system pumps registered pressure spikes, pushing Crew Dragon to use the backup pump. SpaceX was able to resolve that issue, effectively restarting the pumps and confirming healthy operation. Several hours later, the backup pump (“Loop B”) suffered another minor issue but was again returned to healthy operations. Simultaneously, Crew-1 astronauts found themselves stuck at an (admittedly comfortable) cabin temperature of 23C (~73F).

More pressingly, three of four heaters used to warm the propellant fed to Crew Dragon’s small Draco maneuvering and attitude control thrusters were automatically disabled a few hours after liftoff. Essential for most operations in orbit and necessary for Dragon to be allowed to remain docked with the ISS, restoring the functionality of at least one of the three heaters was essential, and SpaceX was thankfully able to restore function to all three by relaxing excessively conservative limits in the spacecraft’s flight software. Thanks to SpaceX’s fast work, Dragon is now in perfect health and ready for two crucial Draco burns at 11:20 am and 12 pm EST (UTC-5) on Monday, November 16th and is still scheduled to arrive at the ISS around 11 pm EST.

Days prior, NASA and SpaceX completed a multi-day “flight readiness review (FRR),” the results of which made SpaceX the first private company in human history to be qualified by a national space agency for routine astronaut launches. As is now more or less routine, the SpaceX Falcon 9 rocket assigned to NASA’s Crew-1 mission performed flawlessly over the 12 minutes it was involved in the launch, including nominal booster and upper stage performance, a successful booster landing at sea, and a smooth Dragon deployment from Falcon 9’s expendable second stage.

In a small point of concern, Crew Dragon capsule C207 (colloquially named Dragon Resilience by its crew) appeared to suffer a minor hardware or software fault shortly after orbital insertion, offering the first public glimpse behind the scenes as ground teams coordinated with Dragon’s orbiting astronaut crew to diagnose and fix the issue.

According to information revealed by SpaceX and NASA officials as they interacted with Crew-1 NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japanese (JAXA) astronaut Soichi Noguchi, Crew Dragon’s fault detection software was tripped sometime after reaching orbit. Both thermal control system (TCS) “loop” pumps – likely referring to pumps used to circulate a liquid-based radiator system to maintain capsule temperature – experienced off-nominal pressure spikes, causing the spacecraft computer to switch to the second pump (“Loop B”).

As SpaceX’s main earth-to-ground communications team member (CapCom) noted, the TCS pump issue was far from critical given that both pumps appeared to be healthy – and one of those two redundant pumps functioning healthily – moments after Dragon alerted its passengers to the issue. Deemed to be not a showstopper, SpaceX continued the mission and permitted Crew Dragon to begin its first orbit-raising thruster burn – the first of a fairly complex series of ‘phasing’ burns needed to safely rendezvous with the International Space Station (ISS).

Unfortunately, due to a 24-hour weather delay from November 14th to November 15th, the complexities of orbital rendezvous mean that Crew Dragon’s Crew-1 mission to the ISS will involve a roughly day-long cruise phase. Had SpaceX been able to launch on the 14th, the cruise phase would have been just 8.5 hours long – perhaps the fastest crewed US space station rendezvous ever. Crew-1 will thus align quite closely with SpaceX’s Demo-2 astronaut launch debut, although likely not interspersed with manual astronaut piloting tests this time around.

On top of Crew Dragon’s thus far successful performance, Falcon 9 also completed a task critical for future Crew Dragon launches when new booster B1061 safely landed aboard SpaceX drone ship Of Course I Still Love You (OCISLY). While normally a distinctly secondary objective, booster recovery was all but essential for SpaceX and NASA during the Crew-1 launch after NASA’s recent reveal that B1061 has been assigned to launch Crew-2 as early as March 31st, 2021. In the likely event that the Falcon 9 booster is in good condition and NASA signs off after shadowing SpaceX’s refurbishment process, SpaceX will also become the first private company in history to launch astronauts into orbit on a flight-proven rocket booster. Additionally, thanks to plans to reuse Crew Dragon capsule C206 of Demo-2 fame, Crew-2 will also mark the first time in history that US astronauts launch into orbit in a reused space capsule.

If the Crew-1 cruise phases goes according to plan, Crew Dragon will autonomously ferry Hopkins, Glover, Walker, and Noguchi from a ~200 km (~125 mi) parking orbit to the International Space Station (ISS) between now and Monday, November 16th, nominally docking with the space station around 11 pm EST (04:00 UTC 17 Nov). From liftoff to reentry, Crew-1 is expected to be the longest continuous spaceflight of a US spacecraft in American history, spending approximately six months in orbit. For JAXA astronaut Soichi Noguchi, his Crew-1 launch also made him the third astronaut in human history to fly to orbit on three separate vehicles.

Ultimately, for SpaceX, the company has never been closer to achieving its foundational goal of enabling the affordable expansion of humanity into space than it is after today’s successful Crew-1 launch.

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.

Published

By

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.

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.

Tesla confirms significant detail regarding V4 Supercharger

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.

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 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.
