While SpaceX has spent the better part of three weeks inspecting the first flight-proven Starship to survive a high-altitude launch and landing, the company appears to have decided to retire the rocket instead of flying it again.

On May 25th, four days after Starship serial number 15 (SN15) was reinstalled on one of SpaceX’s two suborbital launch mounts, a crane was attached to its nose and a transporter staged beside it. One day later, the historic Starship prototype was lifted off of Mount B, installed on that transporter, and rolled away from the launch pad and back towards SpaceX’s Boca Chica, Texas Starship factory.

The day after Starship SN15 was reinstalled on a launch mount, giving SpaceX unrestricted access to its aft, all three of the rocket’s flight-proven Raptor engines – the first of their kind to survive the flight profile intact – were removed. Given the significant value of tearing down and inspecting the first flight-proven high-altitude Raptors, that removal was likely guaranteed regardless of the future of SN15, though it certainly left the Starship at a crossroads.

Having already had its six used landing legs removed, Starship SN15 was left more or less declawed on the launch mount as fans watched with bated breath to see if new legs or engines would be installed. For better or worse, while CEO Elon Musk did indicate that SpaceX “might try to refly SN15 soon” less than two days after its historic landing, it quickly became clear that the company had decided against reuse.

To a degree, especially if SN15’s flight-proven Raptor engines were rendered unusable – as they appear to have been – by exposure to water immediately after touchdown, “reusing” the Starship would be more symbolic than anything. With a thorough inspection, it would be easy enough to determine that the Starship’s structures and mechanical/hydraulic systems would be up for a second launch, but the slow ~10 km (6.2 mi) flight profile ships SN8 through SN11 and SN15 completed was already only relevant for testing Starship’s exotic, unproven method of landing.

In that sense, another fully successful ~10-km launch and landing would only benefit Starship development insofar as it would increase confidence in the landing profile by proving that the first success wasn’t a fluke – however incredibly unlikely that might be. Of note, SpaceX also has not plans to recover the first space-proven Starship, instead (nominally) performing a soft-landing in the Pacific Ocean if the prototype makes it through its inaugural spaceflight without issue.

If that “Orbital Test Flight” is a perfect success, SpaceX will likely have enough confidence – and regulators enough data – to proceed to the first attempt to recover an orbital Starship on land. In the meantime, with orbital launch site buildup now moving at a breakneck pace and tens of millions of dollars of custom pad hardware, giant cranes, and months of work sitting a few hundred feet away from the landing pad, attempting to push the envelope with SN15 likely just isn’t worth the risk.

All but hidden behind Starship SN16, SpaceX recently began stacking the first flightworthy Super Heavy booster. (NASASpaceflight – bocachicagal)

SN15 is also a historic piece of hardware after its successful landing and there are signs – namely the location SpaceX has moved the rocket to – that the Starship will be put on permanent display beside the factory that built it. There’s a limited possibility that Starship SN16 – all but finished – could be sent to the launch site instead of heading straight to the scrapyard, but any testing would necessarily delay orbital pad construction and any flight activity would likely have to expend SN16 in the ocean rather than risk a land landing.

Ultimately, it’s looking more and more likely that SpaceX would rather go all-in on Starship’s inaugural orbital launch attempt, even if that means little to no ground or flight test availability for a few months.

When Elon Musk spoke with CNBC’s David Faber in an interview at Giga Texas, he reiterated the idea that Optimus will be one of Tesla’s biggest products. Seemingly to highlight the CEO’s point, the official Tesla Optimus account on social media platform X shared what could very well be the most impressive demonstration of the humanoid robot’s capabilities to date.

Optimus’ Newest Demonstration

In its recent video demonstration, the Tesla Optimus team featured the humanoid robot performing a variety of tasks. These include household chores such as throwing the trash, using a broom and a vacuum cleaner, tearing a paper towel, stirring a pot of food, opening a cabinet, and closing a curtain, among others. The video also featured Optimus picking up a Model X fore link and placing it on a dolly.

What was most notable in the Tesla Optimus team’s demonstration was the fact that the humanoid robot was able to complete all the tasks through a single neural network. The robot’s actions were also learned directly from Optimus being fed data from first-person videos of humans performing similar tasks. This system should pave the way for Optimus to learn and refine new skills quickly and reliably.

Tesla VP for Optimus Shares Insight

In a follow-up post on X, Tesla Vice President of Optimus (Tesla Bot) Milan Kovac stated that one of the team’s goals is to have Optimus learn straight from internet videos of humans performing tasks, including footage captured in third person or by random cameras.

“We recently had a significant breakthrough along that journey, and can now transfer a big chunk of the learning directly from human videos to the bots (1st person views for now). This allows us to bootstrap new tasks much faster compared to teleoperated bot data alone (heavier operationally).

“Many new skills are emerging through this process, are called for via natural language (voice/text), and are run by a single neural network on the bot (multi-tasking). Next: expand to 3rd person video transfer (aka random internet), and push reliability via self-play (RL) in the real-, and/or synthetic- (sim / world models) world,” Kovac wrote in his post on X.

Starship Flight 9 nears as SpaceX’s Starbase becomes a Texan City

SpaceX’s launch site is officially incorporated as Starbase, TX. Starship Flight 9 could launch on May 27, 2025.

SpaceX’s Starbase is officially incorporated as a city in Texas, aligning with preparations for Starship Flight 9. The newly formed city in Cameron County serves as the heart of SpaceX’s Starship program.

Starbase City spans 1.5 square miles, encompassing SpaceX’s launch facility and company-owned land. A near-unanimous vote by residents, who were mostly SpaceX employees, led to its incorporation. SpaceX’s Vice President of Test and Launch, Bobby Peden, was elected mayor of Starbase. The new Texas city also has two SpaceX employees as commissioners. All Starbase officials will serve two-year terms unless extended to four by voters.

As the new city takes shape, SpaceX is preparing for the Starship Flight 9 launch, which is tentatively scheduled for May 27, 2025, at 6:30 PM CDT from Starbase, Texas.

SpaceX secured Federal Aviation Administration (FAA) approval for up to 25 annual Starship and Super Heavy launches from the site. However, the FAA emphasized that “there are other licensing requirements still to be completed,” including policy, safety, and environmental reviews.

On May 15, the FAA noted SpaceX updated its launch license for Flight 9, but added: “SpaceX may not launch until the FAA either closes the Starship Flight 8 mishap investigation or makes a return to flight determination. The FAA is reviewing the mishap report SpaceX submitted on May 14.”

Proposed Texas legislation could empower Starbase officials to close local highways and restrict Boca Chica Beach access during launches. Cameron County Judge Eddie Trevino, Jr., opposes the Texas legislation, insisting beach access remain under county control. This tension highlights the balance between SpaceX’s ambitions and local interests.

Starbase’s incorporation strengthens SpaceX’s operational base as it gears up for Starship Flight 9, a critical step in its mission to revolutionize space travel. With growing infrastructure and regulatory hurdles in focus, Starbase is poised to become a cornerstone of SpaceX’s vision, blending community development with cutting-edge aerospace innovation.

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.
