SpaceX CEO Elon Musk has officially confirmed that the company’s next Falcon 9 launch will destroy the flight-proven booster and upper stage “in Dragon fire”, a cryptic reference to the ultimate purpose of the sacrifice.

Known as SpaceX’s In-Flight Abort (IFA) test, the mission is designed not to place any particular payload in orbit but to demonstrate that Crew Dragon – the company’s first human-rated spacecraft – can ensure astronaut safety even if faced with a worst-case scenario during launch. IFA will mark Crew Dragon’s second dedicated abort test and second launch on a SpaceX Falcon 9 rocket, although the mission’s brand-new spacecraft will have to suffice with a suborbital jaunt before hopefully splashing down intact in the Atlantic Ocean.

If everything goes as planned, SpaceX has every intention of reusing the IFA Crew Dragon capsule on a future mission, although it’s unclear what that mission might look like. It’s unlikely that a reused SpaceX spacecraft will fly NASA astronauts anytime soon but it’s possible that the company will refurbish the vehicle for an entirely private astronaut launch or transform it into the first uncrewed launch of a next-generation Cargo Dragon (Dragon 2). Regardless, given the challenges posed by the In-Flight Abort, Crew Dragon’s survival is far from guaranteed.

Given that such an abort scenario is by definition a possibility, it’s likely the case that SpaceX’s engineers are almost certain that Crew Dragon should be able to survive such an ordeal, but the spacecraft will likely be pushed to its limits and it’s often much harder to ensure that everything works as intended at those limits.

In-Flight Abort by the numbers

Formerly scheduled to fly since-destroyed Crew Dragon capsule C201, SpaceX was forced to shuffle its spacecraft scheduling, reassigning Crew Dragon capsule C205 – originally expected to launch SpaceX’s first NASA astronaut mission – to support the In-Flight Abort. Featuring upgrades designed to prevent the failure mode that led to C201’s violent explosion, C205 will now have to survive a series of extremely challenging environments.

The IFA test is designed to prove that Crew Dragon can escape a failing Falcon 9 rocket during the most mechanically stressful point of launch. Occurring around 80-100 seconds after liftoff and known as Max Q, it’s the point where Falcon 9’s velocity and altitude combine to create the most friction and pressure the rocket’s windward parts will experience on their climb to orbit. For Crew Dragon, this means its SuperDraco abort engines will have to work fight upwards against air that is functionally (but not literally) much thicker than it is at other points during flight – a battle that will simultaneously put even more pressure (mechanical stress) on the spacecraft’s surfaces.

Pictured with Starship and Super Heavy, Max Q can sometimes correlate with spectacular clouds that form and pulse along the nose of a rocket – caused because the pressure quite literally condenses the water vapor in the air. (SpaceX)

Purely from a numerical perspective, the pressure at Max Q is typically around 30-35 kPa (4.5-5 psi), which doesn’t sound like much but can easily become a force to be reckoned with when the surface area of the rocket or spacecraft being impacted is as large as Crew Dragon (let alone Starship). For reference, Crew Dragon capsules likely have a conical surface area on the order of 30,000 square inches (~19 m²), meaning that the spacecraft is subjected to a total mechanical load of 50-60 metric tons (~130,000 lbf) at Max Q.

Traveling as fast as Mach 2.5 (860 m/s) at an altitude of 28 kilometers (17 mi) at the point where Crew Dragon will ignite its abort thrusters and attempt to escape, that very act of escape will likely magnify the mechanical stresses on the capsule even further. During Crew Dragon’s 2015 Pad Abort, for example, the spacecraft went from a standstill to 155 m/s (345 mph) in 7 seconds – an average acceleration of about 2.3 Gs. Crew Dragon C205 could thus find itself traveling almost Mach 3 (more than a kilometer per second) just seconds after separating and may ultimately reach a peak altitude of almost 75 km (45 mi).

This is all to simply say that Crew Dragon is going to be subjected to an array of varying extremes in a very short period of time, during and after which it must still successfully control its orientation, avoid tumbling, detach its trunk section, and deploy a series of parachutes to achieve a fully-successful test. Additionally, the In-Flight Abort test will see Crew Dragon launch on an almost orbit-worthy Falcon 9 upper stage (lacking only a functional Merlin Vacuum engine) and thrice-flown booster B1046.

According to CEO Elon Musk, it simply is not going to be possible to prevent the historic booster – the first Falcon 9 Block 5 rocket ever launched – from being destroyed shortly after Crew Dragon attempts its escape. Once Dragon departs Falcon 9, the upper stage will likely be torn to shreds by the supersonic airstream suddenly buffeting it, ultimately exposing Falcon 9 B1046’s unchanged interstage – effectively a giant, open cylinder closed at its base.

Likely still travel supersonic, the results of the airstream entering Falcon 9’s interstage and finding no exit will likely be akin to a glass cup smashing mouth-first into a brick wall with a bowling ball taped to its bottom. Thankfully, Falcon 9 B1046 has already successfully supported three orbital-class launches since it debuted in May 2018, completing its third flight just seven months later. The booster will be missed and the opportunity cost (at least several more orbital-class launches) is definitely non-zero, but its sacrifice sill be for a good reason.

As Musk notes, if the In-Flight Abort goes as planned, it could pave the way for Crew Dragon’s first NASA astronaut launch – known as Demo-2 – as few as 6-8 weeks later. For now, Crew Dragon’s IFA test is scheduled to launch no earlier than (NET) January 18th, likely around 8 am EST (13:00 UTC).

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss

Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.

Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.

Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.

Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.

Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.

The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.

Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.

The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.

Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again

Published

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.
