SpaceX wins NASA funds to build and test Starship’s orbital refueling technology

On September 27th, NASA announced a new round of Tipping Point funding worth a total of $43.2M that will be dispersed among 14 separate companies, all focused on advancing “important technologies necessary for sustained exploration of the Moon and Mars.”

Aside from Blue Origin and a dozen others, SpaceX received $3M to work with NASA’s Marshall Space Flight Center (MSFC) to build and test “cryogenic fluid couplers”, a type of nozzle Starship will need to refuel in orbit.

Noted multiple times over the years (and in recent days) by both SpaceX and CEO Elon Musk, an extremely robust and reliable method of orbital refueling is essential to the success of Starship’s current designed – perhaps more so than any other single aspect of the next-generation launch vehicle. Although Starship-Super Heavy will likely offer respectable performance in single-launch mode, the implicit need to recover and reuse both booster and spacecraft takes a big chunk out of the rocket’s potential capabilities.

Much like Falcon 9 and Heavy must sacrifice performance for booster landings, Super Heavy will also need to retain some amount of propellant for its boostback and landing burns. However, while just 1 kg of orbital payload is lost for every ~5-10 kg of extra hardware and propellant on the booster, things are far more consequential when discussing orbital stage reusability. Every single kilogram of hardware and propellant meant for Starship recovery and reuse will result in a 1:1 reduction in payload capacity. This becomes highly consequential when recovering the spacecraft involves the addition of something like 100-200 metric tons worth of wings, fins, heat shield tiles, batteries, propellant, and more.

As such, SpaceX is faced with a conundrum: to make spaceflight truly cheap, full reusability is a necessity, but full reusability almost fundamentally constrains the resultant rocket’s performance and utility. SpaceX’s solution: prolific orbital refueling on the order of anywhere from 1-10+ dedicated tanker launches for every Starship launch. By refueling in Earth orbit, be it low Earth orbit or something much more eccentric, Starship can be extremely reusable while still offering performance that even a similarly-sized, fully-expendable rocket couldn’t begin to compete with.

Although the theory behind SpaceX’s strategy is undeniably sound, the fact remains that orbital refueling has never been tested anywhere close to the scale, speed, or reliability Starship will need for numerous in-orbit refuelings to be a practical solution. Assuming SpaceX uses every ounce of Starship and Super Heavy’s performance for each tanker launch to low Earth orbit (LEO), Starship will have to be able to repeatedly and rapidly transfer at least 150 metric tons (330,000 lb) of liquid oxygen and methane in microgravity conditions.

Without Earth’s gravity and the force of multiple Raptor engines to help things along, it could be quite a challenge to transfer hundreds of tons of propellant in a reasonable timeframe while in orbit. In fact, SpaceX already has Space Act Agreements in place with NASA centers to mature orbital propellant transfer technology. The September 27th award simply continues that relationship, although this particular case involves the first direct funding from NASA – meant to help SpaceX over the “tipping point”.

This time around, SpaceX will work directly with NASA MSFC to build and test actual prototypes of the nozzles (“cryogenic fluid couplers”) Starship will use to mate and refuel in orbit.

“SpaceX will collaborate with NASA’s Marshall Space Flight Center in Huntsville, Alabama, to develop and test coupler prototypes – or nozzles – for refueling spacecraft such as the company’s Starship vehicle. A cryogenic fluid coupler for large-scale in-space propellant transfer is an important technology to aid sustained exploration efforts on the Moon and Mars.”

Elon Musk has confirmed that Tesla will begin high-volume production of the Class 8 all-electric Semi this year. 

He shared his update in a post on social media platform X.

Musk confirms Tesla Semi production ramp

Tesla CEO Elon Musk reaffirmed on X that the Semi is finally moving into volume production, posting on Sunday that “Tesla Semi starts high volume production this year.”

The update comes as Tesla refreshed its Semi lineup on its official website, an apparent hint that the program is transitioning from limited pilots into wider commercial deployment. As per Tesla’s official website, two variants of the Semi will be offered to consumers: Standard and Long Range.

The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile and a gross combination weight rating of 82,000 pounds. The Long Range version pushes driving range to 500 miles, with Tesla noting a higher curb weight of about 23,000 pounds, likely due to a larger battery pack.

Both trims support fast charging, with Tesla stating that the Semi can recover up to 60% of its range in 30 minutes using compatible charging infrastructure.

Broader Tesla Semi rollout

Tesla has already delivered production Semi units to select partners, including snack and beverage giant PepsiCo as well as logistics behemoth DHL, which confirmed that its truck operates daily in California, traveling roughly 100 miles per day and requiring charging just about once a week.

The company has also partnered with Uber Freight, as noted in a Benzinga report, with Tesla executives previously describing the agreement as a way for fleet operators to experience the Semi’s lower operating and maintenance costs firsthand.

With Musk now publicly committing to high-volume production, the Semi appears poised to move beyond pilot programs and into scaled commercial use, an important step in Tesla’s wider push to electrify heavy-duty and long-range trucking.

Tesla tops France reliability rankings, beating Toyota for the first time

The milestone was celebrated by CEO Elon Musk on social media platform X.

Tesla has overtaken Toyota to become France’s most reliable car brand in 2025, as per a new nationwide reliability ranking published by Auto Plus magazine.

The milestone was celebrated by CEO Elon Musk on social media platform X.

Tesla tops reliability ranking in France

Tesla ranked first overall in Auto Plus’ 2025 reliability study, surpassing long-time benchmark Toyota across all powertrain types, including gasoline, hybrid, and electric vehicles.

The ranking, published on February 6, 2026, evaluated early problems reported in 2025 on vehicles registered in France since January 1, 2018, with fewer than 150,000 kilometers on the odometer, as noted by a Numerama report. This marked Tesla’s first appearance in the magazine’s reliability rankings, which was enabled by the company’s growing vehicle population in the French market.

According to the publication, Tesla vehicles showed no recurring major defects beyond isolated suspension arm issues, which are covered under the company’s four-year or 80,000-kilometer warranty. Other reported issues were described as minor, including occasional screen glitches and door handle concerns.

Why this ranking differs from earlier criticism

Tesla’s top placement contrasts sharply with past assessments from the German Automobile Club (ADAC), which previously ranked the Model 3 and Model Y low in its technical inspection reports. Auto Plus noted that those inspections were focused heavily on factors such as brake disc wear, which are not necessarily the best benchmarks for overall vehicle reliability.

By focusing instead on real-world reliability data and early ownership issues, Auto Plus’ methodology offered a broader picture of how vehicles perform over time rather than how individual components age under inspection standards. The publication emphasized that electric vehicles, with far fewer moving parts than combustion-engine cars, are not inherently less reliable.

While the ranking supports the case that electric vehicles can match or exceed the reliability of traditional brands, the magazine acknowledged limitations in its analysis. Still, Tesla’s debut at the top of the list underscores how perceptions of EV durability are shifting as more long-term data becomes available in major automotive markets like France.

The United Auto Workers (UAW) has publicly expressed solidarity with Swedish union IF Metall as its strike against Tesla continues, adding international attention to the extended labor dispute in the European country. 

UAW supports IF Metall’s strike

In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden. UAW Region 8 Director Tim Smith stated that the union fully supports IF Metall’s efforts to secure a collective bargaining agreement with the automaker.

“UAW stands with IF Metall workers on strike against Tesla, fighting for a collective bargaining agreement. UAW Region 8 Director Tim Smith pledged the UAW’s full support and solidarity,” the UAW International Union stated in its post

IF Metall launched its strike against Tesla Sweden in late 2023 over the electric car maker’s refusal to sign a collective agreement. The action has since been supported by other unions through sympathy strikes affecting ports, logistics, and service operations.

Tesla Sweden has maintained that it complies with Swedish labor laws and offers competitive pay and benefits, though the company has not publicly commented on the UAW’s latest show of support.

Tesla owners get union attention

Pro-union groups in Sweden have recently expanded their outreach beyond Tesla’s facilities and workforce. Activists have begun distributing informational leaflets against the EV maker directly on Tesla vehicles parked across Stockholm, as per a report from Swedish outlet Dagens Arbete.

The yellow slips, designed to resemble parking notices, urge regular Tesla owners to pressure the company into signing a collective agreement. Organizers involved in the effort have argued that the leaflets are intended to simply inform consumers rather than single out individual owners. When owners are present, however, activists stated that they explain the dispute verbally.

Tesla has not issued a public response regarding the leaflet distribution campaign as of writing.
