SpaceX’s Starlink satellites spark fights between astronomy, spaceflight fans

Just a handful of hours after SpaceX successfully placed all 60 of its first Starlink v0.9 satellites in orbit, ground observers began capturing and sharing spectacular nighttime views of the spacecraft. Soon after, fans and practitioners of astronomy and spaceflight began bickering.

The topic of concern: light pollution, not from lights on the ground but from sunlight-reflecting satellites in orbit. Immediately after launch, the ‘train’ of 60 Starlink satellites were undeniably spectacular, easily visible to the eye and as bright or brighter than the brightest stars in the sky. For the most part, reactions seemed to lean more towards awe than concern, but it didn’t take long for people to begin extrapolating from 60 satellites to Starlink’s peak of ~11,900 (an increase of 200X), and some responses began to paint SpaceX’s constellation in a more negative light.

Fans, communicators, and practitioners of astronomy quickly grew into the loudest voice in the room, as fans of SpaceX and Elon Musk started to engage, ultimately making it clear that low Earth orbit (LEO) megaconstellations could soon become a highly controversial topic for unexpected reasons. As is typical of humans in the age of social media, the gentlest hint of controversy and criticism swelled into stone-throwing between two crystallized sides unwilling to breathe and engage in civil debate.

Meanwhile, barely 24-48 hours had elapsed since the first Starlink satellite reached orbit – not their final orbit (550 km) but an insertion orbit at ~450 km. Almost immediately, serious observers noted that the Starlink satellites were rapidly spreading out and dimming as they got to work raising their orbits with onboard ion thrusters. Situated in an urban area, Teslarati photographer Tom Cross described the Starlink ‘train’ as “way too faint to capture” on the evening of May 25th, although they were still subtly visible to the naked eye.

From a practical perspective, it should come as little to no surprise that Starlink satellites are visible – even highly visible – from the ground, particularly in areas with minimal light pollution. SpaceX’s flat-panel design and the location of their antennas means that each satellite will have a metallic, shiny surface constantly facing towards the ground, perfect for reflecting sunlight. Additionally, every satellite has a fairly large solar array, likely measuring about 3m by 12m (10ft by 40 ft). Combined, the 60 satellites have a collective solar array area of more than 2000 square meters (21,500 ft^2), nearly the same size as the International Space Station’s football field-sized arrays.

An astronomical disruption?

However, the visibility of SpaceX’s Starlink satellites for laypeople was never the most contentious concern or a leader of vitriolic responses. Rather, even if the ~12,000 proposed Starlink satellites are minimally visible to the naked eye, they will almost certainly still appear in the sort of long-exposure images used by astronomers to catalog, track, and better understand the universe. This is a reasonable concern and one that should come as little to no surprise, given that astronomy already deals with the thousands of operational and defunct satellites, rocket upper stages, and pieces of large space debris already in Earth orbit.

The problem with giant LEO constellations is that satellites in LEO can appear far brighter and far larger than the traditional geostationary satellites used to provide communications services. This is a critical benefit for the spacecraft, as geostationary distances (~36,000 km, 22,000 mi) create major latency (lag) problems for communications networks.

SpaceX CEO Elon Musk didn’t help things by throwing inaccurate information into the mix, claiming that the ISS is visible because it “has lights” and indicating that Starlink satellites would not be visible at night (they will definitely be visible some of the time).

Jonathan McDowell really hit the nail on the head here: it’s far too early to jump to any far-reaching conclusions. Until Starlink satellites have begun routine operations, it’s nearly impossible to accurately predict what they will look like and what impact they will have.

Will Starlink (alongside other constellations from Telesat, OneWeb, and LeoSat) destroy the night sky as we know it, ruining the perfectly untouched cosmos for the rest of eternity? Will Starlink immediately create a global utopia by affordably connecting every single human on Earth to the internet, all while being completely invisible and undetectable from the ground? No, no, no, and no. As with 99.99% of things, the reality will fall somewhere in the middle and its consequences and benefits will be far more grey than black and white.

Update: Elon Musk addresses the controversy over Starlink light pollution

As more levelheaded spaceflight fans and astronomers thankfully point out, we need to wait weeks – if not months or even years – to actually understand the potential impact LEO mega-constellations might have on science and society. It would likely be beneficial for SpaceX – thus far silent – to open a dialogue with those concerned about those potential impacts. It would also serve astronomy well to find ways to cope with space-based infrastructure meant to eventually benefit tens of millions to billions of people, ranging from astronomers themselves to underprivileged members of developing societies. To accept tradeoffs and make compromises is to be human.

Elon Musk’s Boring Company lands a new Middle East deal, and Nashville is about to get faster

The Boring Company signs Abu Dhabi tunnel agreement while adding more Prufrock machines in Nashville.

The Boring Company has signed an agreement with Abu Dhabi to study underground transport and utility tunnels across the emirate, adding a second UAE city to its pipeline as it prepares to also scale up tunneling back home in Nashville.

The deal was signed Thursday at the Liveability and Investment Exhibition (LIVEX 2026) by Boring Company President Steve Davis and Maysarah Mahmoud Salim Eid, director general of the Abu Dhabi Projects and Infrastructure Centre (ADPIC), according to the Abu Dhabi Media Office. Mohamed Ali Al Shorafa, chairman of the emirate’s Department of Municipalities and Transport, attended the signing.

Under the agreement, the two sides will assess feasibility, delivery and operating models for tunnels that could carry passengers or utilities. They will also look at Abu Dhabi’s potential as a regional hub for tunneling work. The current phase is exploratory, and no construction commitment or project budget has been announced.

“Abu Dhabi provides an ideal environment to explore the next generation of underground infrastructure solutions, supported by its ambitious growth vision and strong commitment to advanced technologies,”

Davis said. He added that the company wants to assess how tunnels can “expand urban capacity more efficiently, and enable better use of available space.”

The timing lines up with the money, considering last month, The Boring Company closed a $3 billion Series D led by the UAE and affiliated investors, valuing the company at $23 billion, as Teslarati reported. That round came with a commitment to build more than 150 kilometers of tunnel across the UAE, separate from the Dubai Loop pilot already under contract with Dubai’s Roads and Transport Authority. That pilot covers 6.4 kilometers and four stations linking DIFC and Dubai Mall at a cost of about $154 million.

Back home, The Boring Company projects in Nashville are also scaling up, with the company telling local NewsChannel 5 that a third Prufrock machine could start digging the Music City Loop in late October. A fourth is also targeted before the end of the year. Two machines are already mining Nashville limestone at the same time, and work is underway on a new launch site for the third.

The company said it has made more than 300 design and performance upgrades to its original Nashville machine. It is also working with property owners on more than 40 planned stations, with approvals in place for a future Nashville International Airport connection, a downtown station near the Music City Center, and stops at residential towers and the JW Marriott.

Construction on the Music City Loop began the same evening Tennessee and federal regulators approved the project’s lease in February, and the company targeted its first operational segment for late 2026. Back in Las Vegas, The Boring Company has said it plans to double its Vegas Loop station count by year’s end.

Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.

NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.

The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.

SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.

Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.

The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.

With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab

Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.

Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.

Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”

In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.

The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.

Elon Musk teases TSMC as potential Terafab partner

Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.

Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.

Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.

The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.

TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
