SpaceX wants to land its BFR spaceships “like a skydiver” on Earth and Mars

Speaking at the company’s Hawthorne factory, SpaceX CEO Elon Musk announced a new strategy for efficiently recovering its next-gen BFR’s upper stage, describing a process where the spaceship would rely on a number of unintuitive techniques to reliably land on planets or moons with appreciable atmospheres (i.e. Mars, Earth, Titan). In essence, BFS would end up gliding towards the surface in free-fall, controlling its orientation much like an Earthly skydiver.

Several times throughout the BFR update and private lunar tourism announcement, Musk emphasized just how unintuitive the new procedures would be, stating that “it’s not like anything that people are familiar with – it’s not like an airplane.” His comparison with skydivers is actually rather apt for conveying why this approach is so unusual for a large, flying vehicle like BFR’s spaceship (BFS). Just like skydivers, BFS will have five main control surfaces to control its orientation, pitch, and general dynamics when operating in an atmosphere – two forward fins (like a skydiver’s arms), two rear fins (legs), and a body.

Also like a skydiver, those forward and aft controls are not aerodynamic in the sense of an airplane’s wing or tail fins – in the case of the skydiver and spaceship, they do not generate lift – in pilot and aerospace parlance, a surface that generates no lift is “stalled”. This is likely the main reason that Musk was so intent on conveying his feeling that the spaceship’s new flight regime was unintuitive – in the world of aerospace engineering, particularly for aerodynamicists, intentionally designed stalled control surfaces is almost oxymoronic, akin to an automotive engineer designing a car with square wheels. For all but fighter pilots, stalled aerodynamic surfaces are traditionally avoided like the plague, and can be frequently blamed for aviation-related fatalities.

Even to a layperson, the spaceship landing animation shown might look more like a rock uncontrollably plummeting to the ground than an advanced spaceship meant to land humans on Earth, Mars, and beyond. In essence, the proposal Musk laid out on September 17th takes the high-speed reentry characteristics of NASA’s retired Space Shuttle (aerobraking, S-turns, nose-up reentry), adopts a skydiver’s intuitive and efficient aerodynamic control scheme in free-fall, and replaces said skydiver’s parachutes with a group of high-performance rocket engines, as if a skydiver somehow managed to strap rockets to their feet to gently land on the ground.

SpaceX should have little trouble with the latter task thanks to 15 successful vertical landings of Falcon 9 and Falcon Heavy boosters (and many more to come), while the spaceship’s Shuttle-style orbital reentry profile may be new for SpaceX but has been tackled successfully in the past by other companies/agencies. Free-falling to a successful landing with permanently stalled control surfaces, however, will undoubtedly demand an extensive test campaign in Earth’s atmosphere before SpaceX even thinks of placing humans on the craft, something that Musk foreshadowed in a 2017 Reddit AMA focused on BFR.

“Will be starting with a full-scale Ship doing short hops of a few hundred kilometers altitude and lateral distance. Those are fairly easy on the vehicle as no heat shield is needed.” – Elon Musk, October 2017

BFR’s design and the spaceship’s recovery profile may change further over the next 6-12 months, given that the team’s unintuitive freefall realization seems to be a fresh addition to the Mars rocket. Nevertheless, Musk and COO Gwynne Shotwell have publicly stated that they believe Grasshopper-style spaceship hop tests could commence as early as late 2019 or early 2020, with the first orbital BFR launches starting soon after in the 2020/2021 timeframe.

Tesla Model Y reclaims elusive sales title in competitive market

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

The Tesla Model Y reclaimed an elusive sales title in one of the most competitive markets it is in, outpacing key rivals and formidable competitors to regain the crown it once was a shoe-in for.

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

This is especially prudent in Europe and China, where domestic car companies have been offering attractive and cheap EVs as Tesla alternatives.

However, in September, the Model Y was able to battle back and take over the top sales spot for EVs in Europe.

In September, it had 25,938 sales, and although it was an 8.6 percent decrease compared to the same month in 2024, it was enough to be labeled the best-selling car in the European market, Automotive News reported.

500-mile test proves why Tesla Model Y still humiliates rivals in Europe

There are four vehicles that have been atop the European EV sales rankings for any given month this year: the Renault Clio, which has three titles, the Dacia Sandero, which has won four monthly sales titles, and the Volkswagen T-Roc, which was the best-selling car in the market in August.

The Clio captured the number-two spot in September with 20,146 sales.

Despite a strong September showing for the Model Y, which was its first monthly sales crown of the year, the vehicle has not been a top-three EV in Europe this year. That is still led by the Sandero, Clio, and T-Roc.

Despite that, Tesla’s Model Y is still likely to be one of the best-selling vehicles in the world, if not the best, for the year.

In the United States, it has dominated EV sales charts and has been one of the most popular cars in the region. The same goes for China, where the Model Y has more competition than in Europe, but is so attractive because of its premium look and feel, as well as its tech offerings.

The Model Y has been the best-selling car globally for the past two years, outpacing widely popular gas and EV models from around the world.

Tesla also just finished up its best three-month sales period in its history, delivering just shy of half a million vehicles from July to September.

Tesla dashcam video shows crazy plane crash avoidance maneuver

A Tesla captured video of a crashing plane on an Oklahoma highway, as a shocking video shows a small aircraft coming across a local roadway, with various cars ducking to avoid it.

On October 23, an Oklahoma National Guard OA-1K Skyraider II turboprop plane crashed during a training mission after an engine failure. Both crew members escaped unharmed, but they were not the only ones at risk of injury.

A Tesla Dashcam video shared by a friend of the car’s owner shows the vehicle narrowly avoiding an impact with the plane, swerving left, then back onto its side of the road. It appears to be a serious miracle:

David Bellow, the person who posted the video of the Tesla avoiding the plane, claims it was Full Self-Driving that performed the maneuver, but it is not confirmed. This is what he said:

There are a few hints that suggest it could be Tesla’s Full Self-Driving suite, but it is important to note that neither the company, the driver, nor the friend has confirmed this.

The first hint is the vehicle’s maneuver and subsequent reaction. The car suddenly swerves to the left, which any human would do, but how the vehicle continues to travel as if nothing had happened seems to solidify the idea that FSD could have been involved in avoiding the plane.

Nevertheless, this does not confirm that FSD was in control.

My Tesla did this on FSD (Supervised) v14.1 and the internet went crazy

Most people would likely have stopped in their tracks after avoiding an aircraft while driving.

However, this is not enough proof to definitively say FSD was responsible for the avoidance.

Additionally, the “Jump to Event” button is activated in the video, suggesting that FSD was in control. The vehicle gives this option when something major has occurred, including human intervention.

Regardless of whether the car was on FSD or was controlled manually, it is pretty crazy to have this piece of dashcam footage.

Tesla Full Self-Driving got a minor feature that’s a massive improvement

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.”

Tesla’s Full Self-Driving suite seems to get better with every single release. However, it is also making it more seamless and easier than ever to use for passenger travel, thanks to a recent feature that has flown under the radar.

Tesla started rolling out its v14 iteration of the Full Self-Driving suite a few weeks ago to Early Access Program (EAP) members, and it finally started making its way to the public for the first time earlier this week.

Tesla Full Self-Driving v14.1 first impressions: Robotaxi-like features arrive

The wide rollout of Tesla v14.1.3 was long-awaited, as its capabilities were flexed by the handful of people lucky to have it. However, those sitting with v13.2.9 were still eager to get to their hands on the new FSD version, especially considering it came with a lot of cool upgrades.

One of which is flying under the radar and not getting as much attention as it should. Although it is a minor feature change from v13, Tesla has made FSD more seamless than ever with a simple fix that it started utilizing with v14.

With v14.1.1, Tesla started rolling out the removal of the “Brake Confirm” feature, which required drivers to touch the brake to activate Full Self-Driving. This is now an optional feature, as it now is defaulted to the off position by the car.

The release notes for the feature state:

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.

You can enable Brake Confirm in Autopilot > Brake Confirm.”

Simply put, you no longer need to touch the brake to confirm your intention to use Full Self-Driving, which is a small but very effective fix.

It makes your car much more active in terms of overall activation, and it is definitely a quicker and more streamlined departure from your current location than ever before.

Here’s a good look at how quick it is:

@teslarati With Tesla Full Self-Driving v14, there is no delay when you start FSD. Press “Start Self-Driving” and you’re on your way #fyp #viral #tesla #teslafsd #fsdv14 ♬ original sound – TESLARATI

The feature is small, but it is very noticeable with your first uses of FSD v14. Eventually, it will become even more streamlined as Tesla solves self-driving and autonomy, as it will require zero human intervention to get started, which means the “Start Self-Driving” button will also be removed.
