SpaceX’s Starship rocket program just had one of its best nights yet

Published

Before dawn on May 4th, SpaceX successfully fueled a full-scale Starship prototype and (partially) tested an installed Raptor engine for the first time ever – perhaps the Starship program’s best night yet.

While just a small test relative to what’s soon to come, the milestone is still an extremely significant one for SpaceX and its next-generation launch vehicle. Designed to launch atop the Super Heavy booster, both Starship and its booster are meant to be fully reusable, potentially making the launch system one of the cheapest in operation on Earth. Despite that unprecedented full reusability, they should still be able to place dozens (perhaps up to 100-150+) metric tons of payload into orbit in a single launch.

To get to that point, however, SpaceX must develop and demonstrate a cornucopia of technologies and approaches – most of which are unprecedented – at a scale unmatched by ever other launch vehicle in history, save two or three. It was perhaps the most fundamental of those steps that was on the table earlier this morning.

Perhaps the single most important and uncertain part of SpaceX’s ambitious Starship architecture, SpaceX’s May 4th wet dress rehearsal (WDR) was mainly a test of Starship’s overall structure and the manufacturing apparatus SpaceX has created to build it. Despite how exotic and challenging some of Starship’s goals may sound, SpaceX’s approach to production for its newest launch vehicle is arguably the single biggest risk for the program.

Notably, CEO Elon Musk says that the ultimate goal is to roll out a single finished Starship rocket every single week and at a cost of something like $5-10 million per vehicle. Including the Super Heavy booster, the production goals of which remain unknown, SpaceX effectively wants to mass-produce dozens of fully-reusable rockets – all larger (and potentially more capable) than NASA’s Saturn V Moon rocket – for anywhere from a tenth to a hundredth of the cost.

As if those goals weren’t ambitious enough, SpaceX intends to achieve them with perhaps the most spartan, minimalist factory ever attempted for orbital-class rockets. At the moment, all Starship hardware built by SpaceX to date has been manufactured in a series of tents, more recently graduating to a trio of warehouse-sized sprung structures. A large hangar – apparently dedicated to building pad infrastructure – is just shy of complete, while a separate windbreak structure and a vertical assembly building (VAB) are used to stack (assemble) full-scale Starship subsections built inside tents.

Unlike almost every other launch vehicle in history, Starship production – excluding its Raptor engines and certain other subassemblies and parts – is done in tents and is almost entirely divorced of the clean room operations rocket factories are famous for. Despite the extensive use of hand-welded seams and parts on SpaceX’s early Starship prototypes, the company has already proven that it’s well on its way to building Starships in just a week or two.

Meanwhile, Starship SN5 will probably be ready to roll to the launch pad as early as next week, although it may have to wait a bit longer than that if Starship SN4 survives testing.

While it appears that SpaceX only performed a partial wet dress rehearsal with liquid methane and oxygen and completed a test of part of Starship SN4’s installed Raptor engine (known as the preburner), it means that a Starship has survived a truly launch vehicle-like procedure for the first time ever. In other words, Starship SN4’s May 4th success served as SpaceX’s most important verification yet that its exotic Starship manufacturing approach could be viable for building actual orbital-class rockets.

Up next, SpaceX will attempt to perform a full wet dress rehearsal (WDR) and a static fire test of Starship SN4 and its lone Raptor engine. That test attempt could come as soon as this evening.

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.
