SpaceX Starship nails ‘flip’ maneuver in explosive landing video
Update: SpaceX has published a video taken near the launch pad of Starship nailing an exotic ‘flip’ maneuver shortly before a hard landing destroyed the rocket.
Both the company, test directors, and CEO Elon Musk have all made it abundantly clear that despite the explosive end, Starship SN8’s maiden flight was a spectacular success, proving that the rocket is capable of performing several previously-unproven maneuvers and surviving the associated stresses. Notably, according to tweets posted by Musk not long after, Starship SN8 performed almost perfectly, failing a soft landing (already proven by SN5 and SN6) solely because of low pressure in the rocket’s secondary ‘header’ fuel tank.
For unknown reasons, that tank or its associated plumbing were unable to maintain the pressure needed to feed Raptor with enough propellant, resulting in fuel starvation mid-burn. A lack of fuel and surplus of oxygen effectively turned the landing engine into a giant oxygen torch, melting the copper walls of its combustion chamber (hence the green plume). Had the header tank maintained the correct pressure, SN8 would have very likely landed intact (or at least had a much softer landing).
In simpler terms, it seems that Raptor isn’t to blame for Starship SN8’s failed landing and fixing a pressurization problem will be dramatically faster and easier than rectifying a rocket engine design flaw.
In perhaps the most spectacular aerospace demonstration since Falcon Heavy’s 2018 debut, SpaceX’s first full-size Starship prototype came within a hair’s breadth of sticking the landing after an otherwise successful ~12.5 km (7.8 mi) launch debut.
To quote SpaceX’s test director, heard live on the company’s official webcast moments after Starship serial number 8 (SN8) exploded on impact, “Incredible work, team!” For most, praise shortly after a rocket explosion could easily feel nonsensical, but in the context of SpaceX’s iterative approach to development, a Starship prototype failing just moments before the end of a multi-minute test can be considered a spectacular success.
Chock full of surprises, Starship SN8 ignited its three Raptor engines for the third time and lifted off at 4:45 pm CST (UTC-6) on the program’s high-altitude launch debut.
About 100 seconds after liftoff, already representing the longest-known ignition of one – let alone three – Raptor engines, one of those three engines appeared to shut down, causing the two remaining engines to gimbal wildly in an effort to retain control. Another two minutes after that, one of those Raptors also shut down, leaving one engine active. That one engine continued to burn for another minute and a half, producing just enough thrust to more or less maintain Starship SN8’s altitude at apogee while performing a bizarre horizontal slide maneuver.
Finally, at a bit less than five minutes after liftoff, Starship cut off all Raptor engines and began falling back to earth. Looking spectacularly similar to fan-made renders and CGI videos of the highly-anticipated ‘skydiver’ or ‘belly-flop’ maneuver, Starship – belly down – spent around two minutes in a rock-solid freefall, using four large flaps to maintain stability.
Around 4:52 pm, Starship SN8 performed exactly as expected, igniting one – and then two – Raptor engines while fully parallel to the ground to complete an aggressive 90-degree flip, transitioning into vertical flight for an attempted landing. Unfortunately, although it’s difficult to judge what was intentional and what was not, things began to go wrong after that point -visible in the form of one of the two reignited Raptors flashing green before shutting down.
At the same time, the plume of the lone remaining engine flashed an electric green, quite literally consuming its copper-rich internals in an unsuccessful attempt to slow Starship down. According to SpaceX CEO Elon Musk, Raptor performed “great” throughout the launch and landing attempt, with the bright-green plume likely explained by extremely oxygen-rich combustion caused by low “fuel header tank pressure.”
Regardless of the specific cause, Starship SN8 smashed into the ground around 10-20 seconds early, traveling about 30 m/s (~70 mph) too fast. To be clear, in SpaceX’s eyes, the test – primarily focused on demonstrating multi-engine ascent, freefall stability, header tank handover, engine reignition, and a flip-over maneuver – was a spectacular success, completing almost every single objective and seemingly doing so without any major issues.
Clocking in at an incredible (and unexpected) ~400 seconds (~6.5 minutes) from liftoff to explosion, it’s difficult to exaggerate the sheer quantity of invaluable data SpaceX has likely gathered from SN8’s sacrifice. Thanks to SN8’s primarily successful debut, SpaceX’s Starship test and launch facilities (minus the rocket’s remains on the landing zone) appear to be almost completely unharmed, likely requiring only minor repairs and refurbishment. Further, Starship SN9 is effectively complete and patiently waiting a few miles down the road, ready to roll to the launch pad almost as soon as SpaceX has understood the cause of SN8’s hard landing.
Stay tuned for more analysis, photos, and videos as the dust settles.

The Boring Company accelerates Vegas Loop expansion plans
The Boring Company clears fire safety delays, paving the way to accelerating its Vegas Loop expansion plans.
After overcoming fire safety hurdles, the Boring Company is accelerating its Vegas Loop expansion. The project’s progress signals a transformative boost for Sin City’s transportation and tourism.
Elon Musk’s tunneling company, along with The Las Vegas Convention and Visitors Authority (LVCVA) and Clark County, resolved fire safety concerns that delayed new stations.
“It’s new. It’s taken a little time to figure out what the standard should be,” said Steve Hill, LVCVA President and CEO, during last week’s board meeting. “We’ve gotten there. We’re excited about that. We’re ready to expand further, faster, than we have.”
Last month, the company submitted permits for tunnel extensions connecting Encore to a parcel of land owned by Wynn and Caesars Palace. The three tunnels are valued at $600,000 based on country records.
Plans for a Tropicana Loop are also advancing, linking UNLV to MGM Grand, T-Mobile Arena, Allegiant Stadium, Mandalay Bay, and the upcoming Athletics’ ballpark. Downtown extensions from the convention center to the Strat, Fremont Street Experience, and Circa’s Garage Mahal are also in the permitting process.
“Those are all in process,” Hill noted. “We’ve got machines that are available to be put in the ground. I think we’ve reached a framework for how these projects are going to work and how they’ll be permitted from a safety standpoint, as well as a building standpoint.”
The Boring Company has six boring machines, with three currently active in Las Vegas. Last week, TBC announced that it successfully mined continuously in a Zero-People-in-Tunnel (ZPIT) configuration, enabling it to build more tunnels faster, safer, and at a more affordable rate.
Tunneling under Paradise Road is underway as The Boring Company works on the University Center Loop. The University Center Loop is expected to connect to the Las Vegas Convention Center within two months, linking to the Westgate tunnel. The full Vegas Loop will span 104 stations and 68 miles. Even though The Boring Company’s tunnel network in Las Vegas isn’t nearly finished, it has already become a key attraction in the city.
“It’s such a great attraction for shows that are looking at this building (convention center) and we’re going to be connected to everybody in town,” Hill said. “It’s a real difference-maker.”
A few Vegas Loop stations are already operational, including those connected to Resorts World, Westgate, Encore, and all the Las Vegas Convention Center Loop stations. The Downtown Loop, which connects to the downtown area, and the Riviera Station, the hub that leads to Resorts World with Westgate destinations, are also operational.
As The Boring Company accelerates the Vegas Loop, its tunnels are poised to redefine mobility and tourism in Las Vegas, blending cutting-edge technology with practical urban solutions.

Neuralink Blindsight human trials expected to start in the UAE
Neuralink aims to restore vision with its Blindsight BCI implant. First human implant for Blindsight may happen in UAE.
During Elon Musk’s interview at the Qatar Economic Forum, he announced that Neuralink aims to implant its Blindsight brain-to-computer interface (BCI) device in a human patient by late 2025 or early 2026.
Blindsight focuses on restoring vision. A few years ago, Musk mentioned that Neuralink’s BCI devices would restore vision for people, even those born blind.
“The first two applications we’re going to aim for in humans are restoring vision, and I think this is notable in that even if someone has never had vision ever, like they were born blind, we believe we can still restore vision. The visual part of the cortex is still there. Even if they’ve never seen before, we’re confident they could see,” Musk said during Neuralink’s Show & Tell in 2022.
Musk said Blindsight could be implanted into a human patient in the United Arab Emirates (UAE). Neuralink plans to partner with the Cleveland Clinic Abu Dhabi to implant the first human patient with Blindsight.
Elon Musk’s neurotechnology company is partnering with the Cleveland Clinic Abu Dhabi to conduct the first clinical trial of the UAE-PRIME study. Like Neuralink’s PRIME study in the United States, UAE-PRIME will focus on human patients with motor and speech impairments.
Neuralink received Food and Drug Administration (FDA) approval to conduct the PRIME and CONVOY studies in the United States. PRIME tests the capabilities of the company’s Link implant to restore or enable motor and speech in participants. Meanwhile, the CONVOY study explores Link’s ability to control assistive robotic devices. Neuralink already has an assistive robotic arm called ARA that could expand patients’ autonomy beyond smart devices.
Blindsight would probably require a separate study from PRIME and CONVOY. As such, Neuralink might need FDA approval in the United States to start human trials for Blindsight. However, Blindsight already received a “breakthrough device” designation from the US FDA.
In April 2025, Neuralink opened its patient registry to participants worldwide. The neurotechnology company has already implanted its Link BCI device into five patients. Earlier this year, Neuralink welcomed one of its first PRIME study participants as the first patient in its CONVOY study.

Elon Musk just revealed more about Tesla’s June Robotaxi launch
Tesla CEO Elon Musk gave more information about the Robotaxi launch in Austin set for June.
Tesla CEO Elon Musk just revealed more details about the company’s June Robotaxi launch, which will kick off in Austin.
As of right now, Tesla is still set to push out the first Robotaxi rides in Austin, Texas, in early June. These vehicles will be in short supply at first, as Musk says the company is purposely rolling out the fleet in a slow and controlled fashion to prioritize safety. There will be ten vehicles in the Robotaxi fleet to start.
Tesla Robotaxi deemed a total failure by media — even though it hasn’t been released
However, in an interview with CNBC on Tuesday afternoon, Musk also revealed some other new details, including where in Austin the vehicles will be able to go, how many Robotaxis we could see on public roads within a few months, and other information regarding Tesla’s Full Self-Driving suite.
A Controlled Rollout
Tesla has maintained for a few months now that the Robotaxi fleet will be comprised of between 10 and 20 Model Y vehicles in Austin.
The Cybercab, which was unveiled by the company last October, will not be available initially, as those cars will likely be produced in 2026.
Musk said during the CNBC interview that Tesla is doing a low-yield trial at first to initiate a safety-first mentality. It is important for Tesla to launch the Robotaxi fleet in a small manner to keep things in check, at least at first.
As confidence builds and the accuracy of the fleet is ensured, more vehicles will be added to the fleet.
Musk believes there will be 1,000 Robotaxis on the road “in a few months.”
Geofenced to Certain Austin Areas
Tesla will be launching the Robotaxi program in a geofenced fashion that gives the company the ability to control where it goes. Musk says that the areas the Robotaxis will be able to travel to are among the safest neighborhoods and areas in Austin.
This is yet another safety protocol that will ensure the initial riders are not put in dangerous neighborhoods.
Some might be disappointed to hear this because of Tesla’s spoken confidence regarding Robotaxi, but the initial rollout does need to be controlled for safety reasons. An accident or incident of any kind that would put riders’ lives in danger would be catastrophic.
No Driver, No Problem
As the company has rolled out an employee-only version of the Robotaxi program in Austin and the San Francisco Bay Area, some wondered whether the rides would be driverless, as these initial trials for Tesla workers were not. Employee rides featured a human in the driver’s seat to ensure safety.
Tesla says it has launched ride-hailing Robotaxi teaser to employees only
The company did not report whether there were any interventions or not, but it did state that the vehicles traveled over 15,000 miles through 1,500 trips.
Musk confirmed during the interview that there will be no driver in the vehicle when the Robotaxi program launches in June. This will be groundbreaking as it will be the first time that Tesla vehicles will operate on public roads without anyone in the driver’s seat.
Full Self-Driving Licensing
For more than a year, Tesla has indicated that it is in talks with another major automaker regarding the licensing of Full Self-Driving. Many speculated that the company was Ford, but neither it nor Tesla confirmed this.
Musk said today that Tesla has been in touch with “a number of automakers” that have inquired about licensing FSD. Tesla has yet to sign any deal to do so.
