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.

SpaceX — June 28th, 2021

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’s new Cybertruck offering has had its delivery date pushed back once again. This is now the second time, and deliveries for the newest orders are now pushed well into 2027.

According to Tesla’s Online Design Studio, the new All-Wheel-Drive Cybertruck will now be delivered in April 2027. Earlier orders are still slated for early this Summer, but orders from here on forward are now officially pushed into next year:

Just three days ago, the initial delivery date of June 2026 was pushed back to early Fall, and now, that date has officially moved to April 2027.

The fact that Tesla has had to push back deliveries once again proves one of two things: either Tesla has slow production plans for the new Cybertruck trim, or demand is off the charts.

Judging by how Tesla is already planning to raise the price based on demand in just a few days, it seems like the company knows it is giving a tremendous deal on this spec of Cybertruck, and units are moving quickly.

That points more toward demand and not necessarily to slower production plans, but it is not confirmed.

Tesla Cybertruck’s newest trim will undergo massive change in ten days, Musk says

Tesla is set to hike the price on March 1, so tomorrow will be the final day to grab the new Cybertruck trim for just $59,990.

It features:

  • Dual Motor AWD w/ est. 325 mi of range
  • Powered tonneau cover
  • Bed outlets (2x 120V + 1x 240V) & Powershare capability
  • Coil springs w/ adaptive damping
  • Heated first-row seats w/ textile material that is easy to clean
  • Steer-by-wire & Four Wheel Steering
  • 6’ x 4’ composite bed
  • Towing capacity of up to 7,500 lbs
  • Powered frunk

Interestingly, the price offering is fairly close to what Tesla unveiled back in late 2019.

Elon Musk has clarified when SpaceX will first attempt to catch Starship’s upper stage with its launch tower. The CEO’s update provides the clearest teaser yet for the spacecraft’s recovery roadmap.

Musk shared the details in recent posts on X. In his initial post, Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.

“Starship V3 SN1 headed for ground tests. I am highly confident that the V3 design will achieve full reusability,” Musk wrote.

In a follow-up post, Musk addressed when SpaceX would attempt to catch the upper stage using the launch tower’s robotic arms.

“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk clarified. 

His remarks suggest that SpaceX is deliberately reducing risk before attempting a tower catch of Starship’s upper stage. Such a milestone would mark a major step towards the full reuse of the Starship system.

SpaceX is currently targeting the first Starship V3 flight of 2026 this coming March. The spacecraft’s V3 iteration is widely viewed as a key milestone in SpaceX’s long-term strategy to make Starship fully reusable. 

Starship V3 features a number of key upgrades over its previous iterations. The vehicle is equipped with SpaceX’s Raptor V3 engines, which are designed to deliver significantly higher thrust than earlier versions while reducing cost and weight.

Tesla CEO Elon Musk shared that Full Self-Driving (FSD) could receive regulatory approval in the Netherlands as soon as March 20, potentially marking a major step forward for Tesla’s advanced driver-assistance rollout in Europe.

Musk shared the update during a recent interview at Giga Berlin, noting that the date was provided by local authorities.

“Tesla has the most advanced real-world AI, and hopefully, it will be approved soon in Europe. We’re told by the authorities that March 20th, it’ll be approved in the Netherlands,’ what I was told,” Musk stated. 

“Hopefully, that date remains the same. But I think people in Europe are going to be pretty blown away by how good the Tesla car AI is in being able to drive.”

Tesla’s FSD system relies on vision-based neural networks trained on real-world driving data, allowing vehicles to navigate using cameras and AI rather than traditional sensor-heavy solutions. 

The performance of FSD Supervised has so far been impressive. As per Tesla’s safety report, Full Self-Driving Supervised has already traveled 8.3 billion miles. So far, vehicles operating with FSD Supervised engaged recorded one major collision every 5,300,676 miles. 

In comparison, Teslas driven manually with Active Safety systems recorded one major collision every 2,175,763 miles, while Teslas driven manually without Active Safety recorded one major collision every 855,132 miles. The U.S. average during the same period was one major collision every 660,164 miles.

If approval is granted on March 20, the Netherlands could become the first European market to greenlight Tesla’s latest supervised FSD (Supervised) software under updated regulatory frameworks. Tesla has been working to secure expanded FSD access across Europe, where regulatory standards differ significantly from those in the United States. Approval in the Netherlands would likely serve as a foundation for broader EU adoption, though additional country-level clearances may still be required.
