SpaceX Starship to test landing upgrades after two explosions

Elon Musk says he believes Starship SN10 is almost twice as likely to successfully land as Starship SN8. (SpaceX)

After two Starship prototypes aced their high-altitude launch debuts only to suffer last-second landing failures for unique reasons, SpaceX is gearing up for a third launch as early as this week.

Crucially, though Elon Musk’s levelheaded realism (or pessimism) has often seemed to underestimate the actual odds of success, the SpaceX CEO is substantially more confident on Starship’s third launch attempt than he was on the first flight two months ago. Back when Starship serial number 8 (SN8) was preparing to attempt the program’s first high-altitude launch, Musk pegged the probability of a successful launch, freefall, and landing at ~33%.

As it turned out, he wasn’t wrong, but Starship SN8 ultimately made far closer to a total success than almost anyone – inside SpaceX or not – expected it to get on the first try. Less than two months later, Starship SN9 suffered a similar last-second landing failure more than six minutes into the flight, though the root causes of both failures were unique.

In other words, both flight tests served their nominal purpose, uncovering two failure modes that would have eventually reared their heads one way or another. With SN8, Starship was unable to maintain enough pressure in its secondary landing fuel tank to supply two Raptor engines with enough fuel for a landing burn. Starship SN9 failed a few seconds before SN8 when one of the two Raptor engines needed for a flip and landing burn never ignited, causing the rocket to smash into the ground at an angle relative to SN8’s tail-down impact.

As previously discussed on Teslarati, Elon Musk eventually revealed his opinion that SN9’s engine-out failure was potentially avoidable and that SpaceX would change the way future Starships attempt to land in a bid to add more redundancy.

“While SpaceX obviously hasn’t spun around and fixed a complex Starship propulsion issue in a matter of days, Musk eventually revealed his opinion that he, his engineers, or some combination of both “were too dumb” to exploit one obvious way to mitigate the risk of engine failure during [Starship SN9’s] flip and landing. That ‘obvious’ tweak: reignite all three of Starship’s available landing engines, not just two.”

SpaceX wants to launch its next Starship ASAP

By igniting not just two – but all three – Raptor engines during Starship’s flip burn, SpaceX could essentially perform a midair static fire, giving the rocket’s flight computer a few seconds to analyze performance and downselect to the two healthiest engines for the final landing burn. With that change implemented, Starship would theoretically have enough redundancy to land if only two of its three sea-level Raptors performed nominally.

Currently installed on one of two ‘suborbital stands’ at SpaceX’s South Texas launch pad, Starship SN10 will be the first high-altitude prototype to attempt that three-engine flip burn and on-the-fly downselect. Musk says his confidence that SN10 will successfully land is now 60%, an almost twofold improvement over SN8. Starship SN10 could potentially fly as early as this week, though the prototype still needs to complete a nominal three-engine static fire test and the launch has yet to receive FAA approval.

Further down the road, Musk says that SpaceX is working hard to improve Raptor’s deep throttle performance, potentially allowing future Starships to burn two – or even three – engines all the way to touchdown for even more redundancy. Deep-throttling large, complex rocket engines is extraordinarily difficult, though, so that upgrade is likely no less than several months away. In the meantime, Starship SN11 is effectively complete and Starships SN15 through SN18 are being assembled to support a relentless flight test campaign as SpaceX works towards orbital flights.

Tesla says it is working on rides for the handicapped and disabled with Robotaxi

Tesla CEO Elon Musk confirmed that this was a focus by responding, “Absolutely,” to the embedded post on X above. Tesla said it is developing its own “wheelchair-accessible vehicle,” also known as a WAV.

Tesla says on its Robotaxi app that it is working on enabling “accessibility rides” that would give the handicapped and disabled the ability to hail a Robotaxi to get to an appointment.

While Robotaxi will obviously revolutionize the way we travel for our work commutes, daily activities, and other things, but there is true potential to enable serious change for those who cannot drive.

Autonomous transportation would make life easier for those who are unable to obtain a driver’s license. Of course, with today’s ride-sharing platforms, things are much easier than they once were.

However, rides from Uber and Lyft, while plentiful, always have an opportunity to be unavailable in some regions, especially rural ones, due to a lack of drivers.

Robotaxi aims to solve this problem through autonomous transportation, a technology that Tesla has been developing for years.

However, new language in the Robotaxi app shows that Tesla is working on a solution for people who need rides for medical reasons, and it uses a picture of the Robovan to hammer this point home:

Tesla CEO Elon Musk confirmed that this was a focus by responding, “Absolutely,” to the embedded post on X above. Tesla said it is developing its own “wheelchair-accessible vehicle,” also known as a WAV.

This is likely the Robovan, which was unveiled on October 10 at the Robotaxi event last year:

It is pretty interesting to see two Musk ventures working on solutions for those who are physically impaired or have other disabilities. With Tesla, Robotaxi will unlock immense potential for those who are unable to drive themselves, addressing a genuine need in today’s world.

Additionally, Neuralink is continuing its development of technology to fight against various physical and mental disabilities. A great question to ask is, “Which will be more beneficial for humans?”

Tesla gives big hint that it will build Cyber SUV, smaller Cybertruck

“Those are definitely things we’ve considered. Wait & see is probably the best way I can answer that. We’re working on so many innovative & fun things.”

Tesla appears to have given a significant hint that it plans to build two highly anticipated and requested vehicles: the Cyber SUV and a smaller Cybertruck. This potentially indicates that two new cars could be added to the lineup soon.

For some time, Tesla fans have been requesting two things: a true SUV and a more compact Cybertruck. The SUV has been on the minds of fans and owners for some time, as Tesla does not currently build a full-size SUV that competes with vehicles like the Chevrolet Tahoe or Ford Expedition.

Tesla’s longer Model Y did not scale back requests for this vehicle type from fans

Meanwhile, the compact and smaller Cybertruck has been teased for years, especially since the all-electric pickup seems to be a viable option for international markets; however, its size does not seem ideal for the tight roadways in other regions.

Lately, there have been more hints than ever that Tesla is finally considering these two vehicles. It’s all but confirmed, but Tesla has always left breadcrumbs for fans to find and speculate over.

In an interview with Bloomberg, Tesla Chief Designer Franz von Holzhausen said that the company has considered these two vehicles for its lineup, but he would not give a definitive “yes” or “no” regarding their development:

“Those are definitely things we’ve considered. Wait & see is probably the best way I can answer that. We’re working on so many innovative & fun things.”

Recently, the speculation regarding the Cyber SUV has been well-fueled, as a recent promotional video Tesla released seemed to show a mock-up design hiding in plain sight:

Interestingly, Tesla said in a regulatory filing early this year that it would not adopt the Cybertruck’s stainless steel exoskeleton for new vehicles. However, it could still launch a design inspired by the Cybertruck, but using different materials.

As far as the more compact Cybertruck design, this would enable fans in Europe and Asia to purchase the all-electric pickup.

There have been concerns from a regulatory perspective in some countries outside of North America, as the sheer size and sharp edges have caused some concern for other governments:

However, back in 2019, just after the Cybertruck’s unveiling, CEO Elon Musk admitted that there was a place for a smaller version.

Tesla Robotaxi is headed to a new U.S. state following latest approval

“Only a trained employee, contractor, or other person authorized by the company can operate or monitor the vehicles.”

Tesla Robotaxi is headed to a new U.S. state following its latest approval, which was revealed on Friday night.

Tesla has been operating its Robotaxi platform in Texas and California, with Austin being the first city where the company could test a ride-hailing platform without anyone in the driver’s seat.

First launching in Austin in late June, Tesla’s focus has been expanding its service area, its fleet of Robotaxi vehicles, and its rider population, which has grown most recently due to its public launch.

However, Tesla is also filing applications in states where these autonomous driving programs can operate, aiming to expand to all 50 states eventually. CEO Elon Musk said earlier this year that the company should be able to offer Robotaxi rides to roughly half of the U.S. population.

Alongside Texas and California, Tesla recently gained permission to test its Robotaxi in Nevada, marking the third state where it had some form of regulatory permission to perform rides using an unreleased version of the Full Self-Driving suite.

Now, Tesla has gained another approval in a new state, its fourth, marking a significant step in its expansion across the U.S.

In Arizona, Tesla gained regulatory approval to begin testing autonomous vehicles on public roads.

The vehicles in Austin and the Bay Area of California both use what Tesla has been referring to as “Safety Monitors” in the cars. During city operation in Texas, the Safety Monitor sits in the passenger’s seat. When the route takes the car on the highway, the Safety Monitor jumps into the driver’s seat.

In California, the Safety Monitor is always in the driver’s seat.

In Arizona, Tesla will also utilize what a communication said was “Safety Drivers,” insinuating that the monitor would be in the driver’s seat. However, another line in the email states:

“Only a trained employee, contractor, or other person authorized by the company can operate or monitor the vehicles.”

It sounds as if there is the potential for the Safety Monitor to be in either seat, much like Tesla’s process in Austin. However, this is currently unconfirmed.

The new approval marks a drastic step forward for Tesla as it has received two new approvals in just two weeks. Regulatory hurdles seem to still be the biggest bottleneck for Tesla in terms of gaining permissions to operate in new states, but things seem to be moving along pretty well so far.
