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

Published

on

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.

NTSB findings on fatal Tesla crash tell a very different story

The NTSB confirmed the driver, not Tesla’s FSD, caused the fatal Texas house crash.

Published

By

The National Transportation Safety Board released preliminary findings Wednesday confirming that a Tesla driver, not the vehicle’s software, caused a fatal crash in Katy, Texas in June. The driver, 44-year-old Michael Butler, had engaged Full Self-Driving Supervised mode on Rose Hollow Lane, a residential street with a 30 mph speed limit, before manually overriding the system by pressing the accelerator pedal all the way to 100%. Data recovered from the 2025 Tesla Model 3 showed the vehicle was traveling over 70 miles per hour when it struck a home and killed 76-year-old Martha Avila, who was inside. Weather was clear, the road was dry, and it was daylight.

Butler told authorities he had passed out at the wheel. But security camera footage obtained by the NTSB told a different story, and showed the car accelerating through an intersection before leaving the road entirely. Police also found that Butler’s phone had Google searches including the terms “Tesla FSD not aggressive enough 2026” and “Tesla FSD too timid,” raising serious questions about how he was using the system before the crash. Butler has since been charged with manslaughter. The victim’s family has filed a lawsuit against both Butler and Tesla, alleging negligence.

The NTSB findings aligned directly with what Tesla VP of AI Software Ashok Elluswamy had already stated publicly on X in the weeks after the crash, writing that “the driver manually overrode self-driving by pressing the accelerator all the way to 100%.” The data confirmed his account.

Lucid CEO dispels any rumors of bankruptcy: ‘So far from the facts’

Lucid CEO Silvio Napoli responded to rumors of an imminent bankruptcy that was reportedly being mulled after a report stated the automaker was working with the firm AlixPartners to iron out its next steps.

The company felt a massive loss on Wall Street yesterday, as the report essentially pushed the stock down as much as 55 percent on Tuesday.

The report, published initially by Eletric-Vehicles.com, claimed Lucid was essentially in dire straits and was told by AlixPartners, a commonly used restructuring advisor, to either take shares private or file for Chapter 11 bankruptcy protection.

Lucid’s head of Communications, Nick Twork, immediately challenged the report and stated the company “has sufficient liquidity to carry its operations well into next year.”

Now, the company’s CEO is chiming in as well, stating that the report is “so far from the facts that they require a direct response.”

Napoli said:

“Lucid is not considering bankruptcy or a transaction to take the company private. Those reports are false. The Board did not explore either scenario. Period.

As disclosed in our most recent quarterly filing, Lucid has sufficient liquidity to fund its operations well into next year.

We work with outside advisors to improve operational performance and execution. They are not advising Lucid on a take-private transaction or bankruptcy, and any suggestion that they have recommended either course of action to management or the Board is false.

My priority is clear: turn this company around. That is where the leadership team and I are focused.

I look forward to providing a full update during our quarterly earnings call on August 4th.”

It seems pretty clear that Lucid is confident things will be okay, and, to be honest, they should not have much to worry about, especially considering the company has been backed by the Saudi Public Investment Fund (PIF) for years. It has solid financial backing, and its sales, while weak, are pretty much right on par with a company of this age.

Lucid also sent a Cease & Desist letter to the publication for their report.

Lucid shares have rebounded nicely and are up nearly 21 percent at the time of publication. As soon as the company dispelled the rumors of bankruptcy yesterday, the stock began to climb back toward more reasonable levels.

Tesla responds to strange Supercharging pricing error with classy move

Published

Tesla has once again demonstrated strong customer focus by swiftly addressing and fully refunding a bizarre Supercharger pricing glitch that affected drivers in Atlantic Canada.

The issue surfaced earlier this month when the Tesla app began displaying dramatically inflated per-minute charging rates at stations in Prince Edward Island and parts of New Brunswick.

One widely shared screenshot from a Charlottetown, PEI Supercharger showed rates reaching ridiculous levels: $6.00 per minute for the 180-250 kW tier, along with $3.57/min for 100-180 kW and $2.29/min for 60-100 kW.

These figures were several times higher than normal Supercharger pricing in the region.

To put the error in perspective, charging at the highest incorrect rate would have been shockingly expensive.

At 250 kW, a common charging speed at Superchargers, a vehicle pulls roughly 4.17 kWh per minute. Under the glitch, a driver spending just 10 minutes at peak power would face a $60 bill. A typical 20- to 30-minute session to add meaningful range could have cost $120 to $180 or more, before any congestion fees.

Tesla gets another layer of gamification with Free Supercharging on the line

By comparison, standard Canadian Supercharger rates usually fall between $0.25 and $0.60 per kWh, making a similar session cost roughly $15–$40. The erroneous per-minute structure, combined with the inflated numbers, turned what should be a convenient stop into a potential financial shock.

The glitch appears to have started sometime around early July, and quickly drew attention on social media as owners questioned whether Tesla had implemented steep hidden increases. Some drivers even reported seeing $0 charges in their history, indicating broader billing confusion.

Tesla’s official Charging account on X stated that correct pricing would roll out at midnight on July 13, so the fix is already in effect. More importantly, the company announced it would waive all fees for every Supercharger session since July 2. This blanket waiver covers the entire affected period without requiring users to file individual claims, with automated refunds expected soon. The decision affects stations in PEI and nearby areas in New Brunswick and Nova Scotia.

It’s a classy move, and rather than issuing partial credits or forcing owners to submit support tickets, Tesla simply absorbed the cost of the system error and made drivers whole. In an industry where hidden fees and bill disputes are common, Tesla’s proactive, no-questions-asked approach reinforces owner trust and highlights the company’s commitment to service excellence.

The incident, while disruptive for a short time, ultimately showcases Tesla’s ability to own mistakes and prioritize customer satisfaction. Atlantic Canada Tesla owners can now charge with confidence again, knowing the company has their back when technology glitches occur.

In an era of complex EV billing, such transparency and generosity are refreshing and set a positive example for the industry.
