A SpaceX Falcon 9 booster had all four of its landing legs successfully retracted after a flawless fourth launch and landing, highlighting the impressive margins and durability of the rocket’s upgraded Block 5 design.

On April 22nd, Falcon 9 booster B1051 lifted off on its fourth orbital-class mission – also its second 60-satellite Starlink launch this. Around eight minutes later, B1051 successfully landed aboard drone ship Of Course I Still Love You (OCISLY), ending a back-to-back streak of failed ocean recoveries for SpaceX and verifying that the cause of a March 2020 in-flight engine failure had been rectified. After the loss of booster B1056 and B1048 in February and March, it was also simply a relief to have B1051 safe and sound aboard OCISLY, ensuring that the rocket should be able to support another launch in the near future.

After sailing in port on April 26th, SpaceX technicians lifted a booster off of drone ship OCISLY’s deck for the first time since late January – coincidentally (or maybe not) also Falcon 9 B1051. Two days after its arrival in port and transfer onto dry land, SpaceX successfully retracted all of the massive booster’s landing legs in less than three hours and had it ready for transport less than two hours after that. While B1051’s brisk fourth recovery didn’t break any records, it still serves as a reminder of Falcon 9’s impressive durability in light of the landing it experienced just ~85 days prior.

B1051’s successful leg retraction after its fourth launch and landing is particularly impressive for one main reason: after its third launch, the booster suffered perhaps the hardest drone ship landing any Block 5 rocket has thus far experienced.

Taken in March 2019 and February 2020 after Falcon 9 B1051’s first and third launches and landings, the photo below reveals just how hard a landing B1051 experienced after its Starlink-4 launch. Built almost entirely out of carbon fiber composites and mounted directly to the rocket’s tank walls, Falcon’s telescoping landing legs rely on something known as a ‘crush core’ – made out of aluminum honeycomb – that’s designed to intentionally collapse under a very specific amount of stress.

The crush core is situated in the very tip of the cylindrical leg booms and is easily visible above on the left, while it has nearly disappeared in the right (after) photo after an exceptionally hard landing used up what looks like 90+% of the booster’s safety margin. In other words, if B1051 had landed just a little harder after its third launch, it’s possible that the booster’s landing leg booms would have used up all their crush cores and been driven into the kerosene tank they attach to, potentially totaling the Falcon 9 first stage.

Instead, while clearly a rough landing, B1051 appears to have had its landing leg crush cores replaced and was made ready for another Starlink launch less than three months after that exceptionally hard landing. In other words, despite the rarity of similar hard landings over dozens of recent booster landings, SpaceX was apparently almost entirely unconcerned about the rocket’s state.

As usual, the company almost certainly checked the structural integrity of B1051’s major welds and landing leg hardware before certifying the vehicle for its fourth launch, but the fact that its reuse was so seemingly unexceptional is a testament to the sheer durability of SpaceX’s reusable rocket boosters. Thanks to the modularity of its design, B1051 should have no trouble performing at least several more orbital-class launches over the next several months (if not years). More likely than not, the Falcon 9 Block 5 rocket will fly again just two or so months from now on another Starlink mission, of which SpaceX has 20+ nominally scheduled this year alone.

Tesla Full Self-Driving release in the EU gets delayed

Published

Tesla Full Self-Driving’s release in Europe is set to be delayed by at least a few months.

The European Union will not vote on Tesla’s Full Self-Driving (Supervised) on October 6. The draft agenda for the 119th meeting of the Technical Committee on Motor Vehicles lists only a 25-minute “continuation of discussions” on the Netherlands’ Article 39 request, not a decision. The next scheduled TCMV session is in December, which is now the earliest date a bloc-wide vote could occur.

Tesla Europe had pointed to October 6 as a possible EU-wide vote after the Dutch vehicle authority RDW granted the first European type approval on April 10.

That approval, under UN Regulation 171 plus an Article 39 exemption in EU Regulation 2018/858, is the legal file other member states have been recognizing one by one. The same committee has already discussed the request twice without voting.

Elon Musk’s reply to the delay was a single word: “Sigh.”

Seven EU countries have now cleared FSD Supervised on their own roads: the Netherlands, Lithuania, Estonia, Denmark, Belgium, Slovenia, and Czechia. Those seven states represent about 53 million people, or roughly 12 percent of the EU population. An EU-wide authorization still needs a qualified majority: at least 15 of 27 member states representing 65 percent of the bloc’s population, about 292 million people.

Germany, France, Italy, and Spain remain the decisive markets. France has already rejected the current system; several other governments have flagged speed-limit compliance as the main sticking point.

The safety case Tesla is putting in front of those governments is now public. On September 1, Tesla Europe said FSD Supervised was in use by more than 70,000 customers, covering over 1 million kilometers a day, and was 4.1 times less likely to be involved in a crash than manual driving across 100 million kilometers on EU public roads.

An earlier mid-year cut of the same fleet data, covering 65 million kilometers in five approved countries, put the collision advantage at 5.2 times, with zero highway collisions over 41.9 million kilometers. Tesla also reported far fewer automatic emergency braking events, harsh accelerations, and hard swerves than in comparable manual Tesla driving. Those figures are company-reported, not independently audited.

Tesla Full Self-Driving is taking over Europe: fourth country gets FSD approval

The public-health backdrop is harder to dispute. European countries recorded about 19,400 road deaths in 2025, or roughly 53 a day, most of them attributed to human error. FSD Supervised is not unsupervised autonomy; the driver remains legally responsible. But the software is already legal and in daily use across seven member states.

Until TCMV votes, the rest of the EU remains a patchwork: available in Prague and Amsterdam, locked behind review in Paris and Berlin. December is now the next chance to close that gap.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.
