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.
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 Semi finally has an FSD timeline and it’s waiting on the Cybercab
Elon Musk told investors Semi self-driving should start working by early 2027, per today’s earnings.
During Wednesday’s’ Tesla Q2 earnings call, an analyst asked Elon Musk when Tesla would look at autonomy for the Semi. His answer set a real timeline for the first time, noting that self-driving on the Tesla Semi is expected to start working “around the end of this year or early next year”.
Musk framed the delay as a matter of priority, not capability. Tesla’s self-driving team is currently focused on Model 3, Model Y, and Cybercab, the vehicles that make up the overwhelming majority of Tesla’s fleet. Since Semi trucks on the road remain a small fraction of that total even after the recent Nevada factory ramp, Musk said it made more sense to keep the software team’s attention on what he called “the march of nines of safety” for the higher volume vehicles first. Autonomous Semi development is “taking a bit of a backseat for the next six months or so,” he said, before adding that it “will definitely be working next year and in time for the scale-up to high production of the Tesla Semi.”

The timeline lines up with what’s already been showing up on public roads. In June, a Tesla Semi was spotted in Sunnyvale wearing a full validation rig, the same rooftop sensor array Tesla mounts on vehicles ahead of an FSD milestone.
A second unit was seen near Fremont days later with a matching camera suite and lens washers. Separately, Tesla analyst Nic Cruz Patane posted video this month of the production Semi’s exterior camera array, ten AI4 based units built directly into the truck rather than added later.

Musk also gave the reason autonomy on the Semi matters in the first place, a persistent shortage of qualified truck drivers. “There is a really serious shortage of truckers,” he said on the call, framing a self-driving Semi as important both for addressing that shortage and for improving safety and comfort for the drivers running the truck today.
The timing also tracks with the Semi’s production reality. Tesla’s Q2 shareholder letter, dropped language promising the Semi would reach volume production this year. Musk pointed to 4680 battery cell output as the near-term constraint on Semi and Cybercab production. A software timeline landing in early 2027 gives Tesla’s autonomy team room to work while the hardware ramp catches up behind it.
It’s worth nothing that this isn’t necessarily a promise the Semi ships driverless next year. Musk’s own language, self-driving “working” by early 2027, describes internal validation catching up to hardware already riding on every production truck, not a public unsupervised rollout.
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
You can stream it below. Additionally, we will be doing our Live Blog on X and Facebook.

Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.
Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:
It’s coming soon
— Elon Musk (@elonmusk) July 21, 2026
Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.
Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.
Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.
The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.
Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.
