Years before the space agency’s flagship Europa Clipper mission is scheduled to lift off, NASA and SpaceX are already determining the specifics of the launch – including which Falcon Heavy boosters will support it.
On July 23rd, 2021, after years of rumors, NASA officially announced that it no longer planned to launch Europa Clipper on its own SLS rocket and would instead contract with SpaceX to send the spacecraft to Jupiter on a Falcon Heavy. In terms of sheer prestige, no other mission on Falcon Heavy’s manifest comes close. Expected to weigh around six tons (~13,000 lb), Europa Clipper is a building-sized spacecraft that aims to orbit Jupiter for years, performing dozens of flybys of the planet’s icy moons – several of which almost certainly have liquid oceans.
Europa – the mission’s namesake – is its primary focus and whether or not the funding or political motivation for such an ambitious mission transpires, Europa Clipper was always partially meant to be a scouting mission for a nuclear-powered lander. On its own, though, Clipper has already blown past its original $2B budget target from 2013 and is now on track to cost more than $4.5B, making it the most expensive NASA mission currently in development – second only to the ~$9B James Webb Space Telescope (JWST). In other words, NASA is entrusting SpaceX to launch what is perhaps the most expensive mission to the outer solar system in the history of planetary exploration.
That makes it all the more noteworthy that NASA has already given the okay for SpaceX to plan to launch Europa Clipper on a Falcon Heavy rocket with at least two of its three boosters already flight-proven. According to mission scientist Bob Pappalardo, Clipper Mission Design Lead Brett Buffington revealed in spacecraft “System Integration Review” that SpaceX intends to reuse two Falcon Heavy side boosters that are currently scheduled to debut as early as next year on a different NASA mission. Known as Psyche, that mission – also scheduled to fly on Falcon Heavy – is scheduled to launch no earlier than (NET) August 2022 and is designed to explore an asteroid that’s believed to be almost entirely composed of metal.
With Europa Clipper scheduled to launch NET October 2024, that undoubtedly makes this the earliest a Falcon booster assignment has ever been confirmed – and probably the earliest SpaceX itself has assigned flight-proven boosters to a specific mission. It also makes those particular boosters quite special. Unlike Psyche, which will leave plenty of margin for SpaceX to recover at least two of Falcon Heavy’s three boosters, Europa Clipper will need almost every ounce of performance the rocket can give to send the much larger spacecraft much faster and further. Barring a major surprise, that means that Falcon Heavy will launch Europa Clipper in a fully expendable configuration.
For SpaceX, being able to use at least two flight-proven proven boosters on that expendable mission will make expending two Falcon Heavy boosters – which are otherwise capable of launching at least ten times in their lifetimes – a much easier pill to swallow. For NASA, the space agency is likely already familiar with the reality that flight-proven hardware actually improves schedule confidence, which is crucial for a mission like Europa Clipper thanks to its 21-day launch window.
-->Nonetheless, it does still raise the question of whether NASA will allow SpaceX to fly Psyche’s Falcon Heavy side boosters once or even twice more in the more than two years they’ll otherwise have to spend in storage between Psyche and Europa Clipper. A Falcon Heavy rocket is currently scheduled to launch a commercial Moon lander and NASA’s VIPER Moon rover as early as Q4 2023. Most recently, NASA purchased a Falcon Heavy to launch NOAA’s GOES-U weather satellite NET Q2 2024. In 2022 alone, SpaceX also has at least three other non-NASA missions scheduled to launch before Psyche, raising another possibility that Psyche itself might fly on once-flown boosters that would then fly a third, fourth, or even fifth time with Europa Clipper.
That might seem like an unlikely possibility but NASA has already shown that it’s happy to launch Cargo Dragons on boosters with multiple non-NASA missions in their pasts and will soon launch DART – an asteroid impact spacecraft – on another Falcon booster that last launched Starlink satellites. Additionally, with Arabsat 6A and STP-2, SpaceX already demonstrated in 2019 that it can launch Falcon Heavy, recover its two side boosters, and relaunch those same boosters on a different Falcon Heavy mission less than two months later – and for the US military, no less.

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.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. 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-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
