A SpaceX Super Heavy booster was rocked by a substantial explosion and subjected to multiple fires at the launch pad during the rocket’s latest round of testing.

As of 9 pm CDT, July 11th, the fate of the upgraded Super Heavy – known as Booster 7 or B7 – is leaning towards survival but and it won’t be certain until the rocket is drained of all cryogenic propellant and potentially flammable gas and safe for SpaceX employees to approach. The incident began around 4:20 pm CDT, when Super Heavy Booster 7 (or its launch mount) unintentionally ignited a cloud of flammable gas produced during flow test involving most or all of its 33 Raptor engines. In the past, SpaceX has performed “spin prime” tests with Raptors installed on Starship prototypes, flowing high-pressure gas through the engines’ turbines to get them up to operating speeds and pressures. Booster 7’s test ended a bit differently.

When the resulting cloud of well-mixed methane and oxygen gas was accidentally ignited, it functioned like a small fuel-air bomb, rapidly combusting to produce a violent explosion and shockwave. After the initial explosion, the fire also expanded to burn as much of the resulting gas as possible, producing a fireball that briefly reached 80-90 meters (~260-300 ft) in height. CEO Elon Musk – apparently not directly participating in the test – initially stated that the explosion and fire was planned, implying that it was more or less a nominal outcome. Virtually everyone with experience observing Starship testing felt otherwise, however.

To preserve the safety of the few local residents still living at Boca Chica Village, SpaceX is required to issue printed safety warnings well in advance of Starship tests that could create a shockwave capable of shattering glass and injuring locals. SpaceX has never intentionally performed such a test without distributing those warnings and did not distribute a warning before July 11th, all but guaranteeing that no ignition event was planned. A few hours later, Musk deleted his original tweet and posted a different one, confirming that the explosion was “actually not good” and that SpaceX is “assessing the damage.”

For the most part, Booster 7 and the Starbase Orbital Launch Site (OLS) exceeded viewers’ expectations of their sturdiness, exhibiting very little off-nominal behavior after being subjected to a unexpected explosion, shockwave, and fire. Immediately after the event, B7 quickly depressurized its propellant tanks and appeared to leave those vents open, reducing the chances of the booster destroying itself if SpaceX were to lose control. SpaceX also appeared to intentionally avoid using the orbital launch mount’s (OLM) umbilical mechanism to remove propellant from the Super Heavy’s tanks, perhaps concerned that the shockwave might have weakened its connection to B7.

Starship SN4 demonstrates one possible outcome of attempting to use a leaky pad umbilical to detank.

About an hour after the explosion, Booster 7 dumped a large amount of cryogenic liquid out of a new vent located on its aft end, producing a flood that spread around the adjacent pad. It’s unclear if that liquid was nitrogen or oxygen but either way, the emergency propellant dump appeared to cause a fire to start about 100 feet (~30m) from the booster and launch mount. That fire proceeded to burn intermittently for the next two hours, all the while posing a clear and present danger to the rest of the pad and booster if it were to spread in the wrong direction or breach the wrong underground pipe. Instead, SpaceX got lucky and the fire eventually self-extinguished.

In a worst-case scenario, Super Heavy’s engine section and 33 Raptor engines could have been seriously damaged, while the subsequent pad fire(s) could have also significantly damaged crucial pad systems, requiring weeks of repairs. The booster could even be beyond repair. More optimistically, given that SpaceX appears to have gotten lucky enough to avoid a total loss of vehicle, Booster 7 may be fine after some inspections and moderate repairs. The pad damage could also be limited to a single isolated, non-critical piece of equipment catching fire and burning to a crisp

Regardless, SpaceX will need to figure out what exactly caused the explosion and make sure that that failure mode does not appear again. In the meantime, the company recently finished stacking Super Heavy Booster 8, and Starship S24 – installed on a nearby suborbital test stand – is ready to begin its own static fire test campaign in the near future.

Tesla’s Elon Musk considers insane Cybertruck mod: ‘Maybe we should make this’

The Cybertruck won’t do what the video shows (at least not in our lifetime), but a very entry-level version of it could be developed.

Tesla CEO Elon Musk has teased what could potentially be the company’s next big project, and while it is likely many, many years away, it shows the company truly has its sights set on the craziest things the world has seen.

Musk shared a video created by Grok Imagine, the AI tool that is able to take images and turn them into videos, showing a Cybertruck flying above the clouds and buildings of what appears to be a very futuristic city.

There are also massive robots roaming around in the video, so it is obviously an illustration of what life could look like in several generations.

However, Musk, who does not shy away from some really optimistic projects and goals, shared the video on X and said, “Maybe Tesla should make this.”

What is depicted in the video is not what we’d see Tesla create anytime soon. However, the company could potentially engineer something to make the Cybertruck hover, as it plans to do with the Roadster.

Of course, this is likely a huge “if” considering the current state of the car industry. Vehicles are becoming more advanced with every passing day as companies like Tesla, Waymo, and others are working to sort out things like autonomous and driverless travel.

Tesla has been working on somewhat of a similar idea with the Roadster, a vehicle that has been delayed on several occasions because of Musk’s spectacular imagination. Earlier this year, Tesla’s Chief Designer, Franz von Holzhausen, revealed Musk wanted to push the limits of that vehicle even more.

The new Tesla Roadster will be able to fly: Elon Musk

It seems it could be on the way soon, considering Tesla has teased an “epic” demo for the car, which could come before the end of the year.

Tesla has been working to make the Roadster hover, using SpaceX cold gas thrusters. It will also utilize these for what could be an incredibly fast 1.1-second 0-60 MPH acceleration rate that has been teased countless times.

This project that Musk is teasing with the Cybertruck is likely one that we will not see in our lifetimes. However, this is just one example of the outlandish ideas Musk continues to tease for Tesla in the future.

Tesla Model Y L addresses one huge complaint from many owners

If you have ever used a wireless charger inside a Tesla or almost any vehicle, for that matter, you will notice that your phone will charge slowly, and it will get extremely hot. This is mostly due to the inherent inefficiency of electromagnetic induction, which is the process that wireless chargers use to transfer energy to the phone.

The new Tesla Model Y L is officially launching in China at a great price and with all of the awesome features of the original model, but with more space. The vehicle is also addressing one huge complaint that many owners have discussed.

The new Model Y L features a more spacious interior, new front seats with adjustable headrests, captains chairs, and mechanical armrests in the second row, and B Pillar air vents for improved circulation.

Tesla Model Y L officially launched: price, features, and more

However, there are some other features that are flying under the radar, including one that addresses a common complaint of many Tesla owners: wireless charging.

If you have ever used a wireless charger inside a Tesla or almost any vehicle, for that matter, you will notice that your phone will charge slowly, and it will get extremely hot. This is mostly due to the inherent inefficiency of electromagnetic induction, which is the process that wireless chargers use to transfer energy to the phone.

The inefficiency is evident in the heat, as that is the lost energy that should be going to the phone, but does not.

To combat this problem, Tesla has rolled out a new feature with the wireless charging mat in the Model Y L.

Tesla has used small slit air vents in the center of the wireless charger, which separates the two pads, to blow cool air on the phones to prevent overheating:

This will keep the temperature of your phone down and could prevent the dreaded “iPhone too hot” message that deems your device unusable until it reaches a more stable temperature.

Additionally, Tesla has upgraded the driver’s side wireless charger to support 50W charging speeds. The passenger charger remains at 30W.

This is a small but valuable improvement to the wireless charging apparatus could be a game changer, as there have been so many complaints about this feature in other Tesla vehicles.

The long-awaited Tesla Model Y Performance has been spotted zipping around the famed Nurburgring in Germany, a popular location for new vehicles to test their limits ahead of public release.

Earlier this year, Tesla executives Franz von Holzhausen and Lars Moravy both indicated that the updated and upgraded Model Y Performance would be on its way by the end of 2025, and it appears that time is coming close.

New images captured by Wilco Blok and Teslaplaidtokde on X show the Model Y Performance wrapped in camouflage, sporting a handful of new features as the lightning-fast version of the world’s best-selling vehicle prepares for a launch in various markets across the world:

New Features

According to Blok and Teslaplaidtokde, the new Model Y Performance will feature a variety of new improvements compared to the past version.

This is something that was expected, as the launch of the new Model Y over the past year has shown various changes that made a great vehicle even better.

With the performance, there are some improvements to interior aesthetics, but the goal with this particular trim of Tesla vehicles is to improve performance and aerodynamics, bringing a truly first-class experience to one of the best and fastest vehicles on the road.

Expected Performance Metrics

These are not official figures, but this is what is expected based on what has been seen at the Nurburgring:

  • 510 horsepower
  • 0-60 MPH in 3.2-3.4 seconds
  • 280-290 miles of range
  • Anticipating the release of a new Track Mode

The previous iteration of the Model Y Performance featured 503 horsepower and a 0-60 MPH of 3.5 seconds. It also had a top speed of 155, which we believe will be improved with the next version of the Y Performance.

Here is some footage of the Model Y Performance running around the Nurburgring ahead of its release:

Tesla has not yet listed any date or timeframe for the Performance variant to be released. However, it is anticipated to be released by the end of 2025.
