Elon Musk teases expendable version of SpaceX’s reusable Starship rocket

SpaceX CEO Elon Musk says that the company could eventually develop an expendable version of its next-generation Starship rocket.

Starship is extraordinarily ambitious. Even before considering the unproven concepts of orbital propellant refilling and full, rapid reusability that are central to the full system, Starship is a beast. The rocket measures 120 meters (~390 ft) tall and is theoretically capable of producing up to 7590 tons (~16.7M lbf) of thrust at sea level. It’s larger, taller, heavier, and more powerful than any other launch vehicle in history. 33 Raptor 2 engines power Starship’s Super Heavy booster – also more than any other rocket.

Once optimized, SpaceX says that Starship can launch up to 150 tons (330,000 lbs) to low Earth orbit while still recovering the orbital ship and suborbital booster for reuse. CEO Elon Musk has stated that Starship reuse will eventually take hours, enabling multiple flights per day for each ship and booster and dropping the marginal cost of each launch to just a few million dollars.

In comparison, SpaceX’s workhorse Falcon 9 rocket uses simpler Merlin 1D engines, has just 10 of those engines to Starship’s 39 Raptors, produces about 10 times less thrust at liftoff, and can launch about 11% as much payload to orbit while expending its upper stage. Even then, Musk reported in mid-2020 that the marginal cost of a Falcon 9 launch was $15 million – impressively low but still a vivid demonstration of just how far Starship has to go.

Simply ensuring that Starship can reach orbit at all is a major challenge. Successfully recovering Starship and Super Heavy after the fact may be an even bigger challenge and cannot be fully demonstrated until the rocket can consistently reach orbit. SpaceX won’t be able to reuse Starship until it can consistently recover ships and boosters from orbital launches. And there’s no guarantee that early prototypes will be reusable even if they’re recovered.

Until reusability is demonstrated, every “Starship upper stage” will be functionally expendable whether or not Elon Musk wants it to be. Musk likely means that SpaceX may or may not decide to develop a Starship upper stage custom-built for expendable missions. Such a stage would likely take Starship, remove everything extraneous, and reduce its mass as much as possible. Musk has proposed something similar before, noting that SpaceX could develop a “lightened” version of Starship “with no heat shield or fins/legs” for expendable, interplanetary launches.

Further to the contrary, SpaceX’s Starbase factory is already building multiple intentionally-expendable Starships. Ship 26 and Ship 27 feature no thermal protection, have no heat shield tiles, and will not be fitted with flaps, making them impossible to recover or reuse. More likely than not, they will be used to test other crucial Starship technologies like orbital refilling and cryogenic fluid management.

Meanwhile, SpaceX’s multibillion-dollar contract to use Starship to return NASA astronauts to the Moon revolves around a depot ship variant that will store propellant in orbit and cannot return to Earth. The first few Starship Moon landers may also be functionally expendable and only used for one astronaut landing apiece. In short, SpaceX already has extensive plans to build variants of Starship that are either fully expendable or can only be reused in orbit.

Single-use Starships

In early 2023, SpaceX updated the Starship section of its website, revealing that an expendable version of the rocket will be able to launch up to 250 metric tons (~550,000 lbs) to low Earth orbit in a single launch. Saturn V, the next most capable expendable rocket, could launch up to 118 tons (~260,000 lbs) to LEO and cost $1-2 billion per launch. SpaceX publicly advertising the expendable performance of Starship unsurprisingly confirms that the company is considering all of the capabilities its new launch system will offer.

And Starship’s expendable capabilities are significant. Constructed piece by piece over dozens of launches, the International Space Station weighs about 420 tons (~925,000 lbs). Two expendable Starships could launch more usable mass to LEO – truly revolutionary if SpaceX can make Starship launches frequent and routine.

Tesla has officially launched the first several Supercharging posts at a massive station in California, notably including solar canopies and grid-scale batteries to offer completely renewable charging.

Last week, Tesla announced on X that it opened the first 84 Supercharger stalls of a planned 168-stall station in Lost Hills, California. Additionally, the massive Supercharger project features 11MW of solar canopies and 10 Megapack batteries for off-grid charging powered entirely by solar energy.

Tesla completed the first phase of the project just days ahead of the busy Fourth of July holiday weekend, adding that initial construction took just eight months. In addition to the remaining charging stalls, Tesla says it’s building a set of lounge areas, renderings of which can be seen below alongside current photos of the site.

Notably, the site also includes V4 charging posts for the company’s latest available charging speeds, and it’s located near the busy junction between I-5 and Highway 46 in Kern County.

“Thank you [Kern County] and [PG&E] for collaboration and approvals,” Tesla wrote in a follow-up post.

Testing at the LA Diner, plus Musk update on potential Tesla solar Gigafactory

The huge Tesla Supercharger station completed phase one of construction fairly quickly, especially given how long Tesla has been working on its unique Los Angeles diner, drive-in, and Supercharger location. Still, the company was seen performing some testing at the nearly-completed charging station earlier this month, and will reportedly be holding a job fair.

Elon Musk also responded on Monday morning to a post on X, suggesting that Tesla is “thinking about” building a U.S.-based solar Gigafactory in order to help support increased power needs with AI growth, and to bolster domestic solar production.

The driver of a Tesla Model Y survived and walked away from a harrowing accident on Monday in California, only sustaining minor injuries despite the vehicle being impaled by a guardrail.

On Monday morning around 4:34 a.m., the Los Banos division of the California Highway Patrol (CHP) responded to the accident on I-5 near Panoche Road, involving a 23-year-old in a Tesla Model Y. According to a post on social media, the driver veered off the road for unknown reasons in the northbound lane, before crashing directly into the guardrail and impaling the vehicle.

You can read the full message and photos from Los Banos CHP below, as were shared in a Facebook post on Monday afternoon.

This morning a Tesla model y was traveling in the #1 northbound lane of I-5 north of Panoche Rd. For unknown reasons driver allowed V-1 to veer off the roadway, travel through a dirt center divide, and crashed into the fixed metal guardrail. Lucky for the driver he only sustained minor injuries and was able to walk away. Driving a vehicle requires 100% attention to the road. Avoid distractions and focus on driving.

In a statement to SFGate, CHP officer Myles Anderson said that the driver only sustained minor injuries, while no arrests are made and drugs and alcohol are not suspected to have been involved. The report also notes that Tesla’s “cruise control and lane assistance features” were activated, according to Anderson. However, it’s not entirely clear if this is referring to Supervised Full Self-Driving (FSD), or to the cruise control and lane assist features baked into Autopilot.

At the time of writing, CHP has not yet responded to Teslarati’s request for clarification and additional details on the matter.

Cantor Fitzgerald is holding firm on its bullish stance for Tesla (NASDAQ: TSLA), reiterating its “Overweight” rating and $355 price target amidst the company’s release of its Q2 2025 vehicle delivery and production report. 

Tesla delivered 384,122 vehicles in Q2 2025, falling below last year’s Q2 figure of 443,956 units. Despite softer demand in some countries in Europe and ongoing controversies surrounding CEO Elon Musk, the firm maintained its view that Tesla is a long-term growth story in the EV sector.

Tesla’s Q2 results

Among the 384,122 vehicles that Tesla delivered in the second quarter, 373,728 were Model 3 and Model Y. The remaining 10,394 units were attributed to the Model S, Model X, and Cybertruck. Production was largely flat year-over-year at 410,244 units.

In the energy division, Tesla deployed 9.6 GWh of energy storage in Q2, which was above last year’s 9.4 GWh. Overall, Tesla continues to hold a strong position with $95.7 billion in trailing twelve-month revenue and a 17.7% gross margin, as noted in a report from Investing.com.

Tesla’s stock is still volatile

Tesla’s market cap fell to $941 billion on Monday amid volatility that was likely caused in no small part by CEO Elon Musk’s political posts on X over the weekend. Musk has announced that he is forming the America Party to serve as a third option for voters in the United States, a decision that has earned the ire of U.S. President Donald Trump.

Despite Musk’s controversial nature, some analysts remain bullish on TSLA stock. Apart from Cantor Fitzgerald, Canaccord Genuity also reiterated its “Buy” rating on Tesla shares, with the firm highlighting the company’s positive Q2 vehicle deliveries, which exceeded its expectations by 24,000 units. Cannacord also noted that Tesla remains strong in several markets despite its year-over-year decline in deliveries.
