SpaceX’s Starship wins $53M from NASA for full-scale orbital refueling test
SpaceX’s Starship program has won $53 million from NASA to perform a full-scale test of orbital propellant transfer, taking the company and space agency’s relationship on the crucial technology to the next level.
NASA revealed the results of its fifth round of “Tipping Point” solicitations on October 14th, announcing awards of more than $370 million total to 14 separate companies. This year’s investments focused on three main categories: “cryogenic fluid management, lunar surface [operations], and closed-loop [i.e. autonomous] descent and landing capability demonstrations.”
In a fairly predictable outcome, the bulk (~$176 million) went to Lockheed Martin and the United Launch Alliance (ULA), while the other half (~$189 million) was split among the twelve remaining companies. In an upset, however, SpaceX was awarded a substantial contract for a crucial aspect of Starship development.

Today’s Tipping Point contract is technically the second time NASA has awarded SpaceX funding for propellant transfer development. In October 2019, almost exactly one year ago, SpaceX won $3 million “to develop and test…cryogenic fluid coupler [prototypes] for large-scale in-space propellant transfer,” marking NASA’s first direct investment in Starship. It seems that NASA was thoroughly satisfied with the results of that icebreaker test – enough to fund a full demonstration of Starship propellant transfer to the tune of $53.2 million.
As Ars Technica’s Eric Berger notes, NASA investing eight figures in a SpaceX Starship propellant transfer demonstration – let alone some $250 million overall in four separate companies – comes as a major surprise. In doing so, NASA is effectively testing the tolerance of political stakeholders in programs like Orion and SLS – programs that exist more to preserve jobs and prop up Congressional stakeholders. If a magnitude(s)-cheaper and more capable solution like distributed launch and orbital refueling were demonstrated under NASA’s own purview, it might become a lot harder to defend heritage programs that have been hemorrhaging ~20% of the space agency’s annual budget for almost a decade.
NASA says that this round of Tipping Point contracts could last up to five years. Aside from a $41.6 million contract with Intuitive Machines to develop a Moon hopper spacecraft capable of propulsively hopping around the lunar surface, the most interesting awards are focused on “cryogenic fluid management.” Eta Space received $27 million for a “small-scale flight demonstration of a complete cryogenic oxygen fluid management system to be integrated with Rocket Lab’s Photon spacecraft bus and launched on an Electron rocket.
Lockheed Martin won $89.7 million for an “in-space demonstration mission using liquid hydrogen…to test more than a dozen cryogenic fluid management technologies.” ULA, of which Lockheed Martin is a member, was awarded $86.2 million to test “precise tank pressure control, tank-to-tank transfer, and multi-week propellant storage” with a Vulcan Centaur upper stage.

Finally, SpaceX won $53.2 million for a “large-scale flight demonstration to transfer 10 metric tons of [liquid oxygen] between tanks on a Starship vehicle.” Notably, this seems to imply that NASA is effectively funding a single-ship orbital flight test in which a Starship prototype will (most likely) attempt to transfer liquid oxygen between its main LOx tank and a smaller ‘header’ tank.
Coming on the heels of an April 2020 contract that awarded SpaceX $135 million to develop a crewed Starship design optimized for Moon landings, NASA is beginning to put some serious money where its mouth is to develop a wide range of innovative solutions that may enable sustainable human space exploration.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.

Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
