SpaceX talks results of ‘DarkSat’ coating aimed at reducing brightness of Starlink satellites

Published

SpaceX successfully launched another batch of Starlink satellites into space on March 18, the fourth such launch this year. That brings the total number of internet-beaming satellites to 362, which includes two experimental ones. But ever since the initial batch got off the ground, astronomers and skywatchers have voiced concerns over the apparent brightness of the satellites.

That’s because the satellites appear in the night sky as a train of bright white dots marching across the sky. The sight is alarming to scientists who depend on clear skies in order to peer deep into space. Their concern is this: if the satellites are already interfering with telescope observations, what’s going to happen when there are 42,000 in orbit?

Initially, SpaceX has said its Starlink network will consist of 1,584 satellites, all operating in low Earth orbit. But the company has approval from the Federal Communications Commission for 12,000 satellites and could seek permission to launch 30,000 more. And they’re not the only company with space internet ambitions; OneWeb and Amazon have similar constellations planned.

To help assuage their concerns, SpaceX decided to test out an experimental coating that would reduce the brightness of its satellites. SpaceX tested it out on a previous launch, on one individual satellite, aptly named “DarkSat”.

During the live broadcast of the most recent Starlink mission, SpaceX representatives said that the experiment was somewhat successful and that the coating did help to reduce the satellite’s brightness. But SpaceX wanted to try other means to see which technique was the more effective.

“Preliminary results show a notable reduction,” said Jessica Anderson, one of the hosts of the webcast. But just how effective it is remains to be seen.

Astronomers in Chile measured the DarkSat’s brightness and compared it to the rest of the Starlink satellites. The findings show that the DarkSat was about 55% dimmer, which is good news for certain telescopes. Other telescopes, like the upcoming Vera Rubin Observatory will need the brightness reduced even further as the sensitive optics would be greatly affected by the satellites zooming across the sky.

Astronomers ran computer simulations that showed that the Starlink satellites would not only show up as pronounced streaks across images, but would saturate the pixels in the detectors, causing other ghost-like artifacts to appear. Observatories like the Vera Rubin would need the satellites to be at least 10-20% darker to mitigate their effects.

During the broadcast, Anderson also explained that the company was looking into other ideas that could reduce the satellites’ reflectivity even further.

One of those other ideas is a sunshade. SpaceX didn’t divulge too many details, other than the fact the technology would be used on a future mission and that it would deploy like a patio umbrella from the satellite. How that compares to the coating on the DarkSat remains to be seen.

Tesla is preparing to build its most massive Supercharger yet, as it recently submitted plans for an over 400-stall Supercharging station in California, which would dwarf its massive 168-stall location in Lost Hills, California.

The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.

The expansion, adjacent to the existing Eddie World Supercharger, which is currently comprised of 22 older V2 and V3 stalls limited to 150 kW, unfolds across six phases.

Construction on Phase 1 begins later this year with 72 V4 stalls. Subsequent stages will progressively add hundreds more, culminating in over 400 next-generation chargers. Site plans label expansive parking arrays across Phases 1–5 along Calico Boulevard, with Phase 6 design still to be determined.

The project was first flagged by MarcoRP, a notable Tesla Supercharger watcher.

Strategically located midway on I-15 between Los Angeles and Las Vegas, the station targets heavy EV traffic on this high-demand corridor.

The surrounding 20-mile stretch already hosts over 200 high-power stalls (including 40 at 250 kW, 120 at 325 kW, and more), plus 96 in nearby Baker—yet bottlenecks persist during peak travel.

In scale, it eclipses all existing Tesla Superchargers. The current record holder, the solar- and Megapack-powered “Project Oasis” in Lost Hills, California, offers 164 stalls. Barstow’s former leader had 120. Eddie World 2 will be more than double that size, cementing Tesla’s dominance in ultra-high-capacity charging.

Development blends charging with convenience. Architectural drawings show integrated retail: a 10,100 square foot Cracker Barrel, a 4,300 square foot McDonald’s, a 3,800 square foot convenience store, additional restaurants, drive-thrus, outdoor dining, and lease space.

EV-centric features include pull-through bays for Cybertrucks and trailers, ensuring accessibility for larger vehicles and future Semi trucks.

This phased approach minimizes disruption while scaling capacity. It supports Tesla’s broader vision amid rising EV adoption, Robotaxi corridors, and long-haul needs. Once complete, Eddie World 2 won’t just charge vehicles; it will redefine highway stops, turning a dusty desert exit into a futuristic EV oasis.

Tesla makes latest move to remove Model S and Model X from its lineup

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

Tesla has made its latest move that indicates the Model S and Model X are being removed from the company’s lineup, an action that was confirmed by the company earlier this quarter, that the two flagship vehicles would no longer be produced.

Tesla has ultimately started phasing out the Model S and Model X in several ways, as it recently indicated it had sold out of a paint color for the two vehicles.

Now, the company is making even more moves that show its plans for the two vehicles are being eliminated slowly but surely.

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

The change eliminates the $1,000 referral discount previously available to new buyers of these vehicles. Existing Tesla owners purchasing a new Model S or Model X will now only receive a halved loyalty discount of $500, down from $1,000.

The updates extend beyond the two flagship vehicles. New Cybertruck buyers using a referral code on Premium AWD or Cyberbeast configurations will no longer get $1,000 off. Instead, both referrer and buyer receive three months of Full Self-Driving (Supervised).

The loyalty discount for Cybertruck purchases, excluding the new Dual Motor AWD trim level, has also been cut to $500.

These adjustments apply only in the United States, and reflect Tesla’s broader strategy to optimize margins while boosting adoption of its autonomous driving software.

The timing is no coincidence. Tesla confirmed earlier this year that Model S and Model X production will end in the second quarter of 2026, roughly June, as the company reallocates factory capacity toward its Optimus humanoid robot and next-generation vehicles.

With annual sales of the low-volume flagships already declining (just 53,900 units in 2025), incentives are no longer needed to drive demand. Production is winding down, and Tesla expects strong remaining interest without subsidies.

Industry observers see this as the clearest sign yet of an “end-of-life” phase for the vehicles that once defined Tesla’s luxury segment. Community reactions on X range from nostalgia, “Rest in power S and X”, to frustration among long-time owners who feel perks are eroding just as the models approach discontinuation.

Some buyers are rushing orders to lock in final discounts before they vanish entirely.

For Tesla, the move prioritizes efficiency: fewer discounts on outgoing models, a stronger push for FSD subscriptions, and a focus on high-margin Cybertruck trims amid surging orders.

Loyalists still have a narrow window to purchase a refreshed Plaid or Long Range model with remaining incentives, but the message is clear: Tesla’s lineup is evolving, and the era of the original flagships is drawing to a close.

Tesla Australia and New Zealand confirmed the vehicle will feature seating for six passengers.

“As shown in pictures from its launch in China, Model Y L will have a new seating configuration providing room for 6 occupants,” Tesla Australia and New Zealand said in comments shared with techAU.

Instead of a traditional seven-seat arrangement, the Model Y L uses a 2-2-2 layout. The middle row features two individual seats, allowing easier access to the third row while providing additional space for passengers.

Tesla Australia and New Zealand also confirmed that the Model Y L will be covered by the company’s updated warranty structure beginning in 2026.

“As with all new Tesla Vehicles from the start of 2026, the Model Y L will come with a 5-year unlimited km vehicle warranty and 8 years for the battery,” the company said.

The updated policy increases Tesla’s vehicle warranty from the previous four-year or 80,000-kilometer coverage.

Battery and drive unit warranties remain unchanged depending on the variant. Rear-wheel-drive models carry an eight-year or 160,000-kilometer warranty, while Long Range and Performance variants are covered for eight years or 192,000 kilometers.

Tesla has not yet announced official pricing or range figures for the Model Y L in Australia.
