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.

Tesla made a change to the Cybertruck and nobody noticed

Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.

After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.

Tesla Cybertruck earns IIHS Top Safety Pick+ award

Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.

Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:

The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.

Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.

The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.

Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.

Tesla enters interesting situation with Full Self-Driving in California

Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.

The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.

The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.

The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.

It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.

It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.

Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.

The price beats the previous record close, which was $479.86.

Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.

This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.

It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.

Shares closed up $14.57 today, up over 3 percent.

The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.

However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.

Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.

Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.
