SpaceX begins launching new shell of polar Starlink satellites

Published

on

SpaceX has begun launching a new group of Starlink satellites that will eventually create a ‘shell’ of near-polar communications satellites capable of serving some of the most remote customers on Earth.

Known as Starlink Group 3-1, the mission was also SpaceX’s 50th dedicated Starlink launch since the company first launched a full batch of prototype satellites in May 2019. Just three years later, SpaceX’s Starlink constellation is responsible for roughly half of all working satellites currently in Earth orbit – a figure that is likely to continue to grow for the indefinite future.

Falcon 9 lifted off from SpaceX’s Vandenberg Space Force Base (VSFB) SLC-4E pad at 6:39 pm PDT on July 10th carrying 46 Starlink V1.5 satellites – a payload of around 14 tons (~30,000 lb). SpaceX reduced the number of satellites from the usual 53 to account for the mission’s unusual (relative to Starlink) trajectory and target orbit. Instead of the usual dozens of missions to a fairly ordinary 53-degree orbit around Earth’s midlatitudes and equatorial regions, Starlink 3-1 is the first of several planned missions to a near-polar orbit in which satellites will cross Earth’s equatorial plane at an angle of 97.6 degrees

That orbit is technically slightly retrograde or against the direction of Earth’s rotation, which means that Starlink Group 3 launches will have to work against Earth’s rotation – a bit like trying to climb the wrong escalator. It isn’t SpaceX’s first Starlink launch to a near-polar orbit: the company has technically launched 15 Starlink prototypes to a variety of slightly different sun-synchronous orbits very similar to Starlink 3-1’s target. SpaceX also launched a single batch of Starlink Group 2 satellites to a 70-degree semi-polar shell in September 2021. The purpose of the 51 Starlink 2-1 satellites – only 19 of which appear to be operational – is unclear, though, and only 3 of the other 15 prototypes are still in orbit.

As a result, Group 3 could become the first polar Starlink ‘shell’ to truly enter general service. SpaceX already has plans for a second Group 3 launch – Starlink 3-2 – as early as the end of July, and at 46 satellites apiece, as few as eight launches will be needed to complete the 348-satellite shell. Once complete, it should give SpaceX the ability to serve customers in high-latitude and polar regions.

If or when the US Federal Communications Commission (FCC) gives SpaceX permission to activate thousands of intersatellite laser links installed on the ~1000 Starlink V1.5 satellites already in orbit, the new polar shell could even allow Starlink to connect planes, ships, or outposts that are hundreds or thousands of miles from the nearest ground station. In theory, polar Starlink satellites could even connect Antarctic research outposts to the internet.

Starlink 3-1 was SpaceX’s 50th dedicated Starlink launch since May 2019 and 49th operational Starlink launch since November 2019, bringing the total number of working Starlink satellites in orbit to 2518. Of those 2518, more than 2000 have reached operational orbits and are likely serving some of SpaceX’s roughly half a million customers. Thanks to apparent improvements in reliability that have seen only 9 of 1065 Starlink V1.5 satellites suffer technical failures since launches began in November 2021, almost 90% of all the Starlink satellites SpaceX has ever launched are still in orbit – and functional – today.

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 will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory. 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,” Tesla stated. “The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory.”

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 upgrade follows earlier phases of Tesla’s self-funded shuttle 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 rely on 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 non-employees to ride the shuttle free of charge, making it a broader mobility option for the region as the site’s output and workforce continue to scale.

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.
