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

Texas township wants The Boring Company to build it a Loop system
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge.”
The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes.
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.
The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.
Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.
“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.
“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.
The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.
Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.
“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement.
“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”

Tesla Model Y wins 2026 Drive Car of the Year award in Australia
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall.
The Tesla Model Y has been named 2026 Drive Car of the Year overall winner, taking the top honor after being judged as the vehicle that “moves the game forward the most for Australian new car buyers.”
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall, but the vehicle’s Juniper update strengthened its case with new ownership benefits and expanded software capability.
Drive’s overall award compares category winners and looks at which model most significantly advances the local new car market. In 2026, judges pointed to the Model Y’s five-year warranty and the availability of Full Self-Driving (Supervised) as a monthly subscription as key differentiators.
Priced from AU$58,900 before on-road costs, the all-electric crossover SUV offers a lot of value compared to similarly sized petrol and hybrid rivals. The ability to access Tesla’s Supercharger network across Australia also reduces friction for buyers moving to EV ownership.
Owners can add FSD (Supervised) for AU$149 per month. While it still requires driver oversight, the system expands the vehicle’s advanced driver-assistance capabilities and reflects Tesla’s software-first approach.
“The default choice for a reason. The Tesla Model Y makes the transition to electric both effortless and rewarding,” Drive wrote.
The 2025 Model Y facelift also sharpened the vehicle’s exterior, highlighted by a distinctive rear light bar that gives the crossover SUV a more modern road presence.
Drive described the Model Y as a benchmark for combining practicality, efficiency and technology at an accessible price point. With eligibility for federal Fringe Benefit Tax exemptions through novated leasing, its value proposition has improved for numerous buyers.
For 2026, the Model Y’s combination of range efficiency, charging access and software capability proved decisive. Ultimately, the award all but cements the Model Y’s position as one of the most influential vehicles in Australia’s evolving new-car market today.

Elon Musk reiterates rapid Starship V3 timeline with next launch in sight
Musk shared the update in a brief post on X, writing, “Starship flies again next month.”
Elon Musk has confirmed that Starship will fly again next month, reiterating SpaceX’s aggressive timeline for the first launch of its Starship V3 rocket.
Musk shared the update in a brief post on X, writing, “Starship flies again next month.” The CEO’s post was accompanied by a video of Starship’s Super Heavy booster being successfully caught by a launch tower in Starbase, Texas.
The timeline is notable. In late January, Musk stated that Starship’s next flight, Flight 12, was expected in about six weeks. This placed the expected mission date sometime in March. That estimate aligned with SpaceX’s earlier statement that Starship’s 12th flight test “remains targeted for the first quarter of 2026.”
If the vehicle does indeed fly next month, it would mark the debut of Starship V3, the upgraded platform expected to feature the rocket’s new Raptor V3 engines.
Raptor V3 is designed to deliver significantly higher thrust than earlier versions while reducing cost and weight. Starship V3 itself is expected to be optimized for manufacturability, a critical step if SpaceX intends to scale production toward frequent launches for Starlink, lunar missions, and eventually Mars.
Starship V3 is widely viewed as the version that transitions the program from experimental testing to true operational scaling. Previous iterations have completed multiple integrated flight tests, with mixed outcomes but steady progress. Expectations are high that SpaceX is now working on Starship’s refinement.
An aggressive launch schedule supports several priorities at once. It advances Starlink’s next-generation satellite deployment, supports NASA’s lunar ambitions under Artemis, and keeps SpaceX on track for its longer-term Moon and Mars objectives.
