SpaceX’s next Starship starts to take shape as Elon Musk talks next steps
Less than a day after SpaceX successfully hopped a full-scale Starship prototype for the first time, the company has begun stacking the next rocket and Elon Musk is talking next steps.
Almost immediately after Starship SN5 took to the sky on a 150m (500 ft) hop debut, SpaceX CEO Elon Musk was talking about the company’s next near-term goals for the next-generation launch vehicle’s test program. To an extent, he had already offered a rough overview through various interviews and tweets over the last year or so. Aside from continuing to gradually refine Starship and Super Heavy designs and the processes used to manufacture and test those rockets, a few major proofs of concept stand between SpaceX and total confidence in the current architecture.
As far as basic rocketry goes, SpaceX’s 150m Starship hop has functionally proven that the company’s exotic, rule-of-thumb-breaking approach to Starship production and assembly can be feasibly refined into something capable of producing extraordinarily cheap orbital-class rockets. While a massive achievement, it doesn’t guarantee that the rockets produced will be reusable – let alone rapidly and easily reusable.
As of now, it can be safely stated that SpaceX has solved all major challenges involved in routinely and reliably landing and reusing orbital-class rocket boosters (first stages). It’s hard and surprises are always a possibility, but the landing records of Falcon 9 and Falcon Heavy boosters speak for themselves. For the colossal booster Starship needs to reach orbit, the Falcon family’s success means that Super Heavy recovery and reuse is more a question of “when” than “if”.
Starship, on the other hand, is going to offer many different challenges – some unprecedented for SpaceX and others unprecedented in the entire history of spaceflight. For Starship to be able to support a level of reuse compatible with what the Super Heavy booster is likely to achieve, SpaceX will have to create the biggest and most effortlessly reusable orbital-class spacecraft ever built.
Even heavier than NASA’s Space Shuttle orbiter, Starship will also rely almost entirely on the unproven technology of on-orbit cryogenic propellant transfer to reach beyond low Earth orbit (LEO). To survive orbital-velocity reentries while still being rapidly and cheaply reusable, Starship will further have to push the envelope of heat shield technologies. Last but certainly not least, in its current iteration, Starship relies on a truly unprecedented style of recovery to efficiently land back on Earth.
It’s this last bit where CEO Elon Musk’s recent comments and recent activity at SpaceX’s Starship factory come in. According to Musk, SpaceX intends to perform at least several more smaller hops (a la SN5) “to smooth out [the] launch process.” It’s unclear which prototype(s) will be involved in that series of hops but after SpaceX is satisfied with the state of launch operations, the plan is to “go high altitude with body flaps.” Based on past comments, it’s safe to assume that Musk is referring to a plan to launch a Starship to 20 km (~12 mi).
After reaching 20 km, Starship would orient itself belly down – a bit like a skydiver – and quite literally fall its way to ~1 km altitude before attempting an aggressive Raptor-powered pitch-over maneuver and last-second landing. By using Earth’s atmosphere much like a skydiver trying to slow down, Starship will theoretically be able to dramatically reduce the amount of propellant it needs to land.
That high-altitude launch and landing demonstration will also be the first time a Starship truly needs aerodynamic control surfaces (i.e. “body flaps”) to safely complete a flight test. According to NASASpaceflight.com info, Starship SN8 – also the first full-scale prototype to be built out of a different steel alloy – will be the first ship to receive functional flaps and a nosecone. If initial tests go according to plan, SN8 will also be the first ship to attempt a skydiver-style landing as described above. As far as full-scale aerodynamics goes, such a landing is loosely understood at best. For an orbital-class spacecraft, it’s even more of a wildcard.
Regardless, just hours after Starship SN5’s successful hop debut, SpaceX began stacking the first of several already finished Starship SN8 sections. Based on the assembly of past prototypes, the ship’s tank section could reach its full height just a few weeks from now, while subsequent nosecone and flap installations are uncharted territory.

Elon Musk says Tesla will take Safety Drivers out of Robotaxi: here’s when
“The safety driver is just there for the first few months to be extra safe. Should be no safety driver by end of year.”
Tesla CEO Elon Musk said today that the company plans to completely eliminate Safety Drivers from its Robotaxi fleet, which differs from the Safety Monitors it uses.
Tesla’s Robotaxi platform utilizes employees in the front passenger seat during city rides in Austin and the driver’s seat of the vehicles during highway operations in Austin, as well as during all rides in the Bay Area.

Musk said the presence of a Safety Driver “is just there for the first few months to be extra safe,” but there are plans to remove them in an effort to remove the crutches the company uses during the early stages of Robotaxi.
The CEO then outlined a timeframe for when it would remove the presence of an employee in the driver’s seat in both Austin and the Bay Area. He said there “should be no safety driver by end of year.”

Having a Safety Driver or Monitor has been a major point of criticism from Robotaxi skeptics and Tesla critics.
However, Tesla has maintained that its priority in the early stages is the safety of riders, which will keep things running; even a single negative incident could derail self-driving efforts as a whole, including those outside of the company.
Tesla executives have said their attitude toward safety is “paranoid,” but for good reason: an accident could set back the progress that it and many other companies, including rivals like Waymo, have made in the past few years.
For now, it might be a point of criticism for some, but it’s smart in the near term. Musk plans for Tesla to have Robotaxi operating for half of the U.S. population by the end of the year as well, so it will be interesting to see if it can maintain these timelines.

Tesla is already giving Robotaxi privileges hours after opening public app
This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.
Tesla is already giving Robotaxi privileges to those who downloaded the app and joined its waitlist just hours after it launched in the United States.
As the Robotaxi platform has been operating in Austin for several months, Tesla is now allowing the general public to download its app and call for a driverless ride in the city.
Tesla Robotaxi makes major expansion with official public app launch
The company previously sent invitations to select media outlets and Tesla influencers, seeking initial feedback on the performance of the Robotaxi platform.
There have been positive reviews, but, as with any Beta program, some mishaps have also occurred, although none have been significant.
As of the writing of this article, the City of Austin only lists one incident involving a Tesla Robotaxi, noting it as a “Safety Concern,” but not an accident or collision.
This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.
Tesla is already granting Robotaxi access to several of those who have downloaded the app and gotten on the waitlist early:

With the launch of the public app, we were not too sure how soon Tesla would be able to initiate bringing more riders into the Robotaxi program. The immediate admittance for some riders just hours after the launch is a big positive and is surely a sign of strength for Tesla and its Robotaxi program.
What many will look for moving forward is the expansion of the geofence, which does not seem like a problem, as Tesla has already managed to do this on three occasions. The most recent expansion has expanded the service area to approximately 190 square miles.
People will also look for evidence of fleet expansion, a concern that has been a concern for many, especially since Tesla has not been completely transparent about it. They have revealed a recent service fleet growth of 50 percent, but there has been no specific number of vehicles mentioned.

Tesla explains why Robotaxis now have safety monitors in the driver’s seat
The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media.
Tesla has provided an explanation about the presence of safety monitors in the driver’s seat of its autonomous Robotaxi units.
The autonomous ride-hailing service is currently being deployed in Austin and the Bay Area, with more cities across the United States expected to gain access to the service later this year.
Safety Monitors
When Tesla launched its initial Robotaxi program in Austin, the company made headlines for operating vehicles without a human in the driver’s seat. Even with this setup, however, Tesla still had safety monitors in the passenger seat of the Robotaxis. The safety monitors, which do not interact with passengers, have been observed to report issues and other behaviors from the autonomous vehicles in real time.
Safety monitors on the driver’s seat were also employed in the service’s Bay Area rollout, though numerous members of the EV community speculated that this was likely done to meet regulations in California. However, with the expansion of the Austin geofence, riders in Tesla’s Robotaxis observed that the safety monitors in the city have been moved to the driver’s seat as well.
Tesla’s explanation
The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media. Longtime FSD tester Whole Mars Catalog, for one, speculated that the move might be due to Texas’ new regulations for autonomous vehicles, which took effect recently. Interestingly enough, the official Tesla Robotaxi account on X responded to the FSD tester, providing an explanation behind the safety monitor’s move to the driver’s seat.
“Safety monitors are only in the driver’s seat for trips that involve highway driving, as a self-imposed cautious first step toward expanding to highways,” the Tesla Robotaxi account noted.
Tesla has been extremely cautious with its autonomous driving program, particularly with the rollout of its Robotaxi service, which use Unsupervised FSD. This is quite understandable considering the negative media slant that Tesla is consistently subjected to, which could very well result in minute incidents or mistakes by Robotaxis being blown out of proportion.
