For the third time ever, SpaceX has successfully performed a critical static-fire test of an integrated Falcon Heavy, briefly igniting all 27 of its Merlin 1D engines to verify the health and readiness of the rocket.

Per SpaceX’s official confirmation, a “quick-look” inspection of static fire telemetry has indicated that the company’s Falcon Heavy rocket is ready for its second launch in less than three months, a milestone that could also allow both flight-proven side boosters to tie SpaceX’s own record for booster turnaround. Falcon Heavy Flight 3 is now scheduled to launch the US Air Force’s Space Test Program 2 (STP-2) mission no earlier than 11:30 pm ET (03:30 UTC), June 24th. According to SpaceX CEO Elon Musk, the mission will unequivocally be the company’s “most difficult launch ever”.

Coincidentally, on top of being Falcon Heavy’s first scheduled night launch, STP-2 has now also marked the massive rocket’s first nighttime static fire. During this critical test, Falcon Heavy briefly ignites all 27 of its three boosters’ Merlin 1Ds and throttles the engines up to full thrust, much like airliners sometimes set their brakes and throttle up before attempting to take off. The difference between Falcon Heavy and passenger aircraft is nevertheless rather significant, given that Falcon Heavy produces ~15x the thrust of an A380 – the world’s most powerful mass-produced passenger aircraft – at liftoff: 22,820 kN (5.1M lbf) to the massive jet’s meager 1,440 kN (0.3M lbf).

Despite all of that thrust, Falcon Heavy is held down during static fire by eight accurately-named hold-down clamps, themselves a part of a massive transport/erector, which is itself anchored directly to Pad 39A’s concrete foundation. In short, Falcon Heavy (and especially Falcon 9) is not going anywhere until those hold-down clamps are explicitly released. Thanks to SpaceX’s avoidance of the solid rocket boosters used by almost every other modern launch vehicle, Falcon 9 and Heavy rockets can abort at any point prior to clamp release, offering a uniquely broad abort capability.

As such, not only does SpaceX’s dedicated pre-launch static fire fully test the rocket’s health, but the same procedure is essentially repeated in the seconds before clamp release during an actual orbital launch attempt. If at any point Falcon 9’s autonomous onboard computer decides that it doesn’t like any of the thousands of channels of telemetry it’s constantly analyzing, it can command an engine shutdown and total launch abort even if all first stage engines have already ignited and reached full thrust. If routine McGregor, TX acceptance testing – also involving a full static fire – is accounted for, every single Falcon 9 booster technically completes three fully-integrated static fires before its inaugural liftoff. Falcon Heavy is slightly different, as each booster is independent test-fired in Texas but the integrated rocket can only perform static fires at Pad 39A.

After those three critical tests, flight-proven Falcon boosters are subjected to the less stringent few-second static fires SpaceX performs at the launch pad 3-7 days before a given launch. With Falcon Heavy Flight 3, the rocket’s center core, upper stage, and payload fairing are all brand new, fresh from either SpaceX’s Hawthorne factory or McGregor acceptance testing. However, both side cores – Block 5 boosters B1052 and B1053 – are flight-proven, having successfully completed their first launches and landings on April 11th, less than 70 days ago.

Set by regular old Falcon 9 boosters, SpaceX’s current record for booster turnaround time (time between two launches) is 71 days (set in June 2018), while the Block 5 upgrade’s record stands at 74 days (set in October 2018). If Falcon Heavy’s STP-2 launch holds strong on June 24th, B1052 and B1053 will simultaneously tie SpaceX’s Block 5 turnaround record. This would be accomplished despite the added pressure from the US Air Force’s decision to use STP-2 as a sort of dress rehearsal for certifying all flight-proven commercial rockets, an honor (and burden) that likely added extra work, oversight, and scrutiny to the process of refurbishing and relaunching B1052 and B1053.

“[T]he US Air Force has decided that STP-2 presents an excellent opportunity to begin the process of certifying flight-proven SpaceX rockets for military launches. The STP-2-related work is more of a preliminary effort for the USAF to actually figure out how to certify flight-proven commercial rockets, but it will still be the first time a dedicated US military mission has flown on a flight-proven launch vehicle. Down the road, the processes set in place thanks – in part – to STP-2 and Falcon Heavy may also apply to aspirational rockets like Blue Origin’s New Glenn and ULA’s “SMART” proposal for Vulcan reuse.”

In a last-second surprise, SpaceX updated Falcon Heavy center core B1057’s planned drone ship landing site from a brief 40 km (25 mi) to more than 1240 km (770 mi) off the coast of Florida. SpaceX set its current record for recovery distance less than three months ago during Falcon Heavy’s commercial launch debut, in which Block 5 center core B1055 landed nearly 970 km (600 mi) offshore on drone ship Of Course I Still Love You (OCISLY). If all goes well, B1057 – the second finished Block 5 center core – will absolutely crush its predecessor’s record, implying that the booster will likely be subjected to SpaceX’s most difficult reentry and recovery yet.

Tesla Model Y L attracts crowds across China stores

The Tesla Model Y L is shaping up to be a big hit in China.

Tesla has officially rolled out the Model Y L, a six-seat variant of its best-selling SUV, across all showrooms in China, and it is getting a lot of attention from potential buyers.

Images and videos from Tesla stores in China show crowds of people checking out the recently released extended wheelbase all-electric crossover.

Model Y L details

The vehicle, which carries a starting price of RMB 339,000 ($47,180), went live in Tesla China’s configurator this week. Deliveries are scheduled to begin in September, and early media reviews have already been released following the lifting of an embargo.

Unlike a full model refresh, the Model Y L is positioned as a new variant within the existing Model Y lineup. It joins the five-seat rear-wheel drive (RWD) and long-range all-wheel drive (AWD) Model Y variants currently available in China.

The six-seat Model Y L features dual-motor all-wheel drive, a 0–100 km/h time of 4.5 seconds, and an 82.0-kWh battery pack from LG Energy Solution. Its CLTC-rated range reaches 751 km, the highest among Tesla’s Model Y trims.

So far, the reception to the Model Y L appears to be very warm, with photos and videos of stores in locations such as Shanghai and Shenyang showing numerous people checking out the recently released vehicle. Reports from industry watchers in China also suggest that Tesla received about 35,000 orders for the Model Y L on its first day of release.

Market backdrop

The timing of the Model Y L’s release comes as Tesla faces headwinds in China’s competitive SUV segment. Between January and July, Model Y retail sales in the country reached 202,257 units, a 17.15 percent decline compared to the same period last year, according to data cited by CNEVPost. It should be noted, however, that a good portion of this decline was due to the retooling of Tesla’s factories to make way for the new Model Y.

Despite the slowdown, the Model Y remains one of Tesla’s strongest performers globally. By introducing a higher-range, six-seat option, Tesla appears to be positioning the Model Y L as a way to boost demand and appeal to new buyers in a market that was previously only accessible to the much more expensive Model X.

Tesla Model Y L gets disappointingly far production date in the United States

Fans of the extended wheelbase six-seater in the United States are in for a long wait.

The Tesla Model Y L is making a lot of waves in the electric vehicle community, but fans of the extended wheelbase six-seater in the United States are in for a long wait.

This was, at least, according to Tesla CEO Elon Musk, who provided a disappointingly long timeline for the Model Y L’s production in the United States.

The Model Y L

The Model Y L has received near universal acclaim from electric vehicle enthusiasts and auto reviewers in China alike. Priced at just RMB 339,000 ($47,180) and fitted with a spacious and comfortable cabin, the Model Y L seemed destined to become a segment killer. And since the vehicle is also produced in Tesla’s existing Model Y lines, it seemed like the vehicle would be released worldwide soon. 

It was then no surprise that many Tesla community members were keen on asking if the Model Y L will be released in the United States anytime soon. Others also wondered why CEO Elon Musk was very quiet about the vehicle despite all the buzz it was generating. Eventually, Musk did share an update about the Model Y L, but it was not what many expected.

Elon Musk’s update

Amidst the conversations on X about the Model Y L, longtime FSD tester Whole Mars Catalog noted that Elon Musk would not be saying anything about the vehicle until its international release, likely because he would like to avoid an Osbourne Effect on the standard Model Y. Tesla’s sales today are still highly dependent on the standard Model Y, after all, as it is the company’s best-selling vehicle.

Musk responded to the FSD tester, stating that the Model Y L will not start production in the United States until the end of 2026. He also noted that the vehicle might not even make it in America at all, considering Tesla’s focus on self-driving. “This variant of the Model Y doesn’t start production in the US until the end of next year. Might not ever, given the advent of self-driving in America,” Musk wrote in his post.

Musk’s post was received with much disappointment from many X users, some of whom joked that the CEO was risking alienating families with three kids with his comments. The Model Y L, after all, is a legitimate family car that can comfortably seat six, and it seemed like a vehicle that Musk would prioritize considering his stance on people having bigger families. Of course, the CEO might still just be preventing an Osbourne Effect with his comments, but it’s difficult to deny that a 2026 U.S. production date for the Model Y L is still disappointing.

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.
