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 just said some crazy stuff about the Tesla Roadster

Elon Musk appeared on the Moonshots podcast with Peter Diamandis today to discuss AGI, U.S. vs. China, Tesla, and some other interesting topics, but there was some discussion about the upcoming unveiling of the Roadster, the company’s electric supercar that will arrive several years after it was initially slated for release.

Musk made some pretty amazing claims about the Roadster; we already know it is supposed to be lightning-fast and could even hover, if Tesla gets everything to happen the way it wants to. However, the car has some pretty crazy capabilities, some of which have not even been revealed.

On the podcast, Musk said:

“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”

Musk makes a good point: people who buy expensive sports cars with ridiculous top speeds and acceleration rates do not buy them to be safe. They hope they are safe in case of an emergency or crash, but safety is not at the forefront of their thoughts, because nobody buys a car thinking they’ll crash it.

The Roadster is truly going to push the limits and capabilities of passenger vehicles; there’s no doubt about that. Tesla plans to show off the new version car for the first time on April 1, and Musk has only hinted at what is possible with it.

Musk said back in November:

“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveiling ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”

Production is set to begin between 12 and 18 months after the unveiling, which would put the car out sometime in 2027. Hopefully, Tesla is able to stay on track with the scheduling of the Roadster; many people have been waiting a long time for it.

Tesla has launched a hiring initiative for its Robotaxi program in its twentieth country, as the company posted two new jobs in Thailand this week.

Tesla is hiring in Bangkok and Kowloon for the Vehicle Operator position, which is related to data collection, and is the first in Thailand, but the twentieth country overall, as the company tries to expand into other markets.

Tesla has had active job postings for Vehicle Operator positions in the United States, India, Israel, Taiwan, Germany, the Czech Republic, Hungary, the UK, Finland, Switzerland, Sweden, the Netherlands, Austria, Spain, Norway, Italy, and Turkey in past listings.

These postings are not all currently available, likely because the roles have been filled.

Thailand is the most recent, and broadens the company’s potential path to expanding its ride-hailing program, which is only active in the United States in Austin, Texas, and the California Bay Area, so far.

These roles typically involve data collection, which assists in improving Autopilot and Full Self-Driving operation. Tesla’s self-driving programs utilize real-world data that is accumulated and stored, observing vehicle and traffic behavior, as well as tendencies that are performed by human drivers to help increase safety and overall performance.

Overall, the hiring signals Tesla’s aggressive timeline for global dominance in autonomous mobility. Although the company has several high-profile rivals and competitors in the field, it has established itself as a main player and a leader in the development of autonomous technology, especially in the U.S., as its FSD suite is refined on almost a weekly basis.

The Full Self-Driving suite is available in seven countries and territories currently, including the U.S., Canada, China, Mexico, Puerto Rico, Australia, and New Zealand. Its biggest goal for expansion is currently the European market, where regulatory hurdles have been the main bottleneck prolonging its launch on the continent.

Tesla has performed months of testing in various European countries, including France and Spain, and does have support in some areas from various regulatory agencies. However, the company is hoping to get through this red tape and offer its suite in Europe for the first time, hopefully this year.

Tesla has rolled out minor updates to the five-seat Model Y in China, upgrading the vehicle’s center display to a higher-resolution 16-inch 2K screen. The electric vehicle maker also introduced attractive financing options, including 7-year low-interest rates, to offset the new purchase tax on EVs. 

These strategies are aimed at improving the ownership experience and keeping vehicle pricing competitive in the world’s largest electric vehicle market.

Five-seat Model Y gets larger, better display

With its recent update, all three variants of the five-seat Model Y now feature an upgraded 16-inch 2K resolution center display, which replaces the vehicle’s previous 15.4-inch 1080p panel. This screen was already used in the six-seat Model Y L, and it offered improved visual clarity. Tesla China has also updated the Model Y’s headliner to black, giving the vehicle a sleeker appearance.

Prices of the five-seat Model Y remain unchanged at RMB 263,500, RMB 288,500, and RMB 313,500 for the respective trims. This update enhances the cabin experience as domestic rivals are already adopting high-resolution screens. As noted in a CNEV Post report, some domestic automakers have begun rolling out vehicles equipped with 3K-resolution displays. 

New financing offers

Tesla also launched ultra-long-term financing offers for its locally produced models in China, which include the Model 3 sedan, the five-seat Model Y, and the six-seat Model Y L, through January 31, 2026. The 7-year option features an annualized fee rate as low as 0.5%, which is equivalent to 0.98% interest. This is expected to save customers up to RMB 33,479 ($4,790) compared to standard rates.

A 5-year zero-interest plan is also available, and it has been extended to the Tesla Model Y L for the first time. These incentives help offset China’s new 5% purchase tax on New Energy Vehicles (NEVs) in 2026-2027. Some of Tesla’s rivals in China have announced in recent months that they would be covering the purchase tax owed by buyers early this year.
