SpaceX says Starship can beat ‘plasma blackout’ with Starlink antennas

Published

on

SpaceX has asked the FCC to allow Starship and its Super Heavy booster to communicate with Starlink during the rocket’s first orbital launch attempt, potentially unlocking game-changing capabilities.

Filed on June 28th, SpaceX’s Special Temporary Authority (STA) application contains a number of surprising details about the company’s plans to expand the experimental use of its Starlink satellite constellation to communicate with rockets in flight. That effort was first made public in April 2021 when a separate FCC application revealed plans to test Starlink on a Starship prototype. Starship serial number 15 (now known as Ship 15 or S15).

That particular prototype became the first of its kind to successfully launch and land in one piece on May 5th. Nothing is known about whether Starlink was actually used or how the Starship’s lone dish performed during the 10 kilometer (6.2 mi) flight test, but SpaceX’s plans to again combine both two Star– programs do offer some new lines to read between.

Relative to its first Starlink-Starship STA application, SpaceX splits no hairs in the ‘narrative’ attached to its latest request. Specifically, SpaceX repeatedly discusses the potential for Starlink to drastically improve the state of the art of routine spacecraft and launch vehicle telemetry and communications.

“SpaceX intends demonstrate high data rate communications with Starship and the Super Heavy Booster on the ground at the launch site in Starbase, TX during launch, during booster recovery, in flight, and during reentry. Starlink can provide unprecedented volumes of telemetry and enable communications during atmospheric reentry when ionized plasma around the spacecraft inhibits conventional telemetry frequencies. These tests will demonstrate Starlink’s ability to improve the efficiency and safety of future orbital spaceflight missions.

In short, in the two months since SpaceX first requested permission “to operate a single user terminal…during flight tests,” the company appears to have become extremely bullish about Starlink’s potential as a solution for rocket communications. The logical conclusion is that Starlink performed well during its trials aboard Starship S15 on the ground and in flight – possibly even exceeding SpaceX’s own expectations. Simultaneously, SpaceX is in the midst of expanding efforts to certify Starlink for aviation communications and has been generally ramping up tests on aircraft, ships, and road vehicles.

Indeed, at least in theory, the same attributes that allow Starlink to blow traditional consumer satellite communications solutions out of the water could make Starlink a boon for launch vehicle communications. That’s especially true for the test flights of experimental launch vehicles like Starship, where failure is an inevitable part of the development process. However, those launch failures are only beneficial insofar as they expand the knowledge base and allow lessons to be learned.

Data, in other words, is essential, and the more data recovered from test flights, the better. Even on modern rockets, state-of-the-art telemetry usually involves maximum bandwidth on the order of a few hundred to a few thousand kilobits per second, often requiring software and compression gymnastics and uncomfortable triage to ensure that all necessary telemetry keeps flowing.

If Starlink could expand that bandwidth from a few megabits per second (Mbps) to dozens or even hundreds of Mbps, SpaceX could extract unprecedentedly widespread and high-resolution telemetry from Starship and Super Heavy during their first orbital test flight, leaving a wealth of data for likely post-flight failure analyses.

Perhaps most surprising is SpaceX’s claim that Starlink antennas could allow Starship to maintain a strong communications link throughout orbital reentry. Traditionally, all spacecraft capable of reentry produce a superheated sheath of plasma as they careen into Earth’s upper atmosphere. That plasma effectively blocks most radio waves, creating an inevitable several-minute communications ‘blackout’ for any reentering spacecraft.

If Starlink can somehow allow SpaceX to break through that ‘plasma barrier,’ it would give the company an unprecedented capability invaluable for the process of perfecting orbital Starship reentry, descent, and landing – a process Musk expects to involve several unsuccessful attempts. According to SpaceX’s FCC application, Starship’s first orbital launch and reentry attempt could occur as early as August 2021.

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.

By

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.”

Tesla Semi’s official battery capacity leaked by California regulators

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 (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Published

on

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.

Tesla is about to make parking in busy lots less stressful than ever

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:

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.
