Elon Musk says a SpaceX Falcon 9 rocket is about to be "destroyed in Dragon fire"

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 makes big change to encourage Full Self-Driving purchases

Tesla Full Self-Driving was recently proven to be about ten times safer than a human driver in terms of accident frequency.

Tesla has made a big change to its Online Design Studio, hoping to encourage car buyers to purchase Full Self-Driving with their vehicles.

Now, when you look at ordering a car on Tesla’s website, the portion of the page that formerly showed a render of Full Self-Driving capabilities has been replaced by a compilation of the suite’s performance in a variety of challenging scenarios.

It’s a great way to show off FSD’s impressive ability to work through road conditions that can even stump human drivers.

The move is much better than what the page previously illustrated. Now, people can see the true capabilities of the FSD suite and what it could do to change their perspective on how vehicles can be. Instead of a vessel of transportation, FSD turns cars into a semi-autonomous mode of travel.

Tesla Full Self-Driving is statistically very safe, logging about ten times the number of miles between accidents as human drivers, based on recent data the company released.

It is available for purchase in two different ways: an outright purchase for $8,000 or in a monthly subscription for $99. This enables the software to essentially do a vast majority of the legwork of driving. Drivers must keep their eyes on the road and be prepared to take over if an intervention is needed.

However, FSD has been proven to be a very accurate and safe way to travel. Tesla recently released a video of a drive from the Bay Area to Los Angeles, a nearly seven-hour trip, under FSD without a single intervention ever needed:

From a personal perspective, Tesla Full Self-Driving is a great way to travel because it truly takes a lot of the stress out of driving. In the past, I’ve used it during weekend Demo Drives to navigate around my town to see if it could handle some of the tougher traffic in my area. It became such an amazing and convenient alternative that when I went back to my car, I truly missed the advantage of having it.

Tesla offers new feature to save battery and reduce phantom drain

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

Tesla is offering a new feature to help owners save battery and reduce phantom drain, an issue that some have complained of with their cars.

While Teslas are some of the most efficient EVs on the market, they utilize energy and battery life when they’re parked to keep certain features, like Sentry Mode, Summon Standby, and others, active in preparation for potential events that occur.

Keeping these features ready to perform utilizes energy, and if your car is parked at an airport where it could be sitting stagnant for a few days, the battery percentage could start to dwindle pretty significantly.

Because of this, Tesla is rolling out a new feature called “Low Power Mode,” which will automatically disable a handful of settings to combat battery dwindling and phantom battery drain.

Tesla writes in the release notes for the feature:

“When Low Power Mode is enabled, your vehicle will conserve energy by automatically disabling the following features:

    • Sentry Mode
    • Summon Standby
    • Outlets
    • Keep Accessory Power On
    • Keep Climate On and Camp Mode
    • Scheduled Preconditioning
    • Cabin Overheat Protection

While charging with Low Power Mode enabled:

    • Sentry Mode and accessory power will remain available
    • Keep Climate On and Camp Mode are only available when Supercharging

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

This feature seemed to be a reaction to a past issue that an owner had as their Cybertruck continued to utilize energy even though the pickup was parked at an airport and the owner was in Japan. The Cybertruck had utilized a lot of energy to keep standby functions active, which left the owner in an interesting spot when they returned.

CEO Elon Musk stepped in, and it seems this feature might have been a reaction to that situation. This is an ideal thing to use if you’re looking to conserve your battery’s state of charge.

Tesla is bringing back something it took from the Model 3…for a price

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla is bringing back the Model 3’s turn signal stalk in China after removing the part with the refresh of the all-electric sedan early last year.

However, it is going to cost you.

In 2024, Tesla launched the Model 3 “Highland,” a refreshed version of the vehicle that included several large-scale changes. One of the most noticeable was the lack of a turn signal stalk, something the company chose to remove and instead implement turn signal buttons on the steering wheel.

The buttons were met with mixed reviews, as some drivers complained that it was too difficult to get used to them. Others had no problem with the change, noting that it was slightly more convenient for them or that they enjoyed the minimalistic look.

Now, Tesla is offering Model 3 owners in China the opportunity to replace the stalk for a price of ¥ 2,499, or about $350:

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla notes on its website that the service is available for Model 3 vehicles without stalks manufactured after February 7, 2025. Any car without a stalk that was manufactured before that date will have the service available to them in the future.

Installation can be performed at a Service Center or by the owner. However, Tesla notes that it is not responsible for any damages resulting from self-installation and recommends that the part be put in by an employee.

The cockpit of the Tesla lineup has been under intense scrutiny by the company in recent years. After a few changes to things like the stalk, steering wheel shape, and others, Tesla has usually given drivers the chance to have things reverted back to their preferences if they want.

They did this for the Model S and Model X a few years ago after implementing the yoke steering wheel.

The stalk was not supposed to be removed from the Model 3 and Model Y, but Tesla chose to do so with the refresh last year.

It seems the minimalization of the cockpit, overall, is a move that prepares drivers for autonomy, as eventually, Teslas will be void of pedals, steering wheels, and any other apparatus that are used to control the car.
