According to photos posted by the Japanese investor, SpaceX CEO Elon Musk has gifted Yusaku Maezawa a significant piece of Starhopper history, a celebration of the rocket prototype’s successful flight tests and a gesture of thanks for Maezawa’s substantial support.

Back in September 2018, Musk revealed that Japanese billionaire Yusaku Maezawa had become the first true customer for SpaceX’s next-generation Starship launch vehicle. In fact, Maezawa announced DearMoon, a private spaceflight venture with the aim of sending a dozen or so artists on the first commercial crewed mission around the Moon – all for free.

In a bid to assist Starship development and simultaneously secure rights to the massive spacecraft’s first crewed lunar launch, Maezawa committed what is believed to be several hundred million dollars of his personal fortune to SpaceX. In turn, the Japanese billionaire plans to select roughly a dozen artists from around the world and offering them a free ticket aboard Starship’s first crewed circumlunar launch, traveling once around the Moon and returning to Earth after 10 or so days in space.

Perhaps just a few weeks after the DearMoon announcement and Starship event, SpaceX CEO Elon Musk decided to radically change the Starship program, entirely replacing the vehicle’s main structural material of choice – carbon fiber composites – with stainless steel. The primary goal was to dramatically lower the cost of development and vehicle production and speed things up, but Musk quickly realized that steel could unintuitively be better than carbon fiber in almost every way.

After Musk’s decision, SpaceX pivoted from carbon fiber to steel at a spectacular pace. Barely six months after the design change, a SpaceX team had built up its Boca Chica, Texas facilities from almost nothing, begun to build full-scale steel hardware, and nearly completed the first low-fidelity prototype, known as Starhopper. That vehicle began propellant loading and wet dress rehearsal testing in early-April 2019 and although technical difficulties with its next-generation Raptor engines caused several months of delays, it moved into its first flight test campaign three months later.

Starhopper’s first untethered flight was completed successfully on July 25th, reaching an apogee of ~18 meters (60 ft). A little over one month later, Starhopper lifted off for the second time on a significantly more ambitious ~150m (500 ft) flight test, completed successfully after about 60 seconds in flight. That second test would be Starhopper’s last and SpaceX quickly turned its focus to completing the first full-scale, full-fidelity Starship prototypes, known as Mk1 (TX) and Mk2 (FL).

Throughout this process, Yusaku Maezawa has followed along with SpaceX. Rather than a simple lump-sum agreement, the billionaire’s contract with SpaceX is structured much more specifically, essentially allowing the company to unlock additional funding after certain milestones – like Starhopper’s flight tests – are completed. The arrangement is more of a carrot on a stick than something dead-serious – Maezawa is probably not going to completely withhold funding if SpaceX slightly misses exact targets or suffers anomalies during a complex launch vehicle development program.

In order to complete its two flight tests, Starhopper needed some kind of attitude control system (ACS) to remain stable and SpaceX chose a decidedly SpaceX-y solution, simply bolting on flight-proven Falcon 9 thruster pods. Those pods use high-pressure nitrogen to change Falcon 9’s attitude, correctly point the rocket, and settle its propellant while the rocket is in a vacuum (or freefall). They can also provided limited control authority in atmosphere, which is what SpaceX used them for on Starhopper.

As it so happens, Starhopper – now in retirement – is only missing one thruster pod, making it easy to determine which one was gifted to Maezawa. (NASASpaceflight – bocachicagal)

As a gesture of gratitude for Maezawa’s extremely helpful financial support, SpaceX gifted him an entire Starhopper thruster pod. SpaceX often does similar things for major flight milestones, creating commemorative gifts out of retired hardware (rocket tanks, engine bells, grid fins, parachute threads, etc.) that employees are able to purchase. An entire thruster pod is at least a few orders of magnitude above that, a sign of just how grateful SpaceX is to Maezawa.

Of note, in his tweet showing off the thruster pod, Maezawa suggested that “Starship development is going better than expected”, indicating that he may “need to invite a passenger soon” for his planned circumlunar voyage around the Moon. Prior to Starship’s radical shift from carbon fiber to steel, that mission was scheduled no earlier than 2023. In recent months, SpaceX executives have made it clear that they are now targeting Starship Moon landings by 2022, suggesting that the first circumlunar missions – a far easier task than landing – could be possible even sooner than that.

Why SpaceX is finishing another space-internet system that isn’t Starlink

SpaceX launched three final O3b mPower satellites Sunday, finishing a lesser known SES satellite network.

Published

By

SpaceX had an 87 minute window opening at 2:49 p.m. Eastern on Sunday to fly a Falcon 9 out of Cape Canaveral carrying the final three satellites for SES’s O3b mPower constellation, a project that has taken more than a decade to finish since Boeing and SES first signed SpaceX on for the work.

Unlike the thousands of Starlink satellites SpaceX has stacked into orbit over the years, O3b mPower flies in a different neighborhood entirely. The three new satellites, tagged F11, F12 and F13, are headed for medium Earth orbit at roughly 5,000 miles up, more than ten times higher than Starlink’s shell around 340 miles but still a small fraction of the 22,000 miles where old school geostationary satellites sit. That middle position is the whole point, because a satellite that far out needs far fewer siblings to blanket the globe than a low orbit constellation does. Essentially, SES only needed 13 satellites total to build a network offering quick, steady service that used to require thousands of spacecraft.

With most people having heard plenty about Starlink and almost nothing about O3b mPower, SES and SpaceX already blend the two networks for some customers. Both SpaceX and SES sell satellite broadband, but they’re aimed at different buyers. Starlink is built for volume, direct to consumers, RVs, homes, small businesses, plus a growing aviation and maritime business. O3b mPower skips consumers entirely and sells enterprise grade connectivity to airlines, cruise lines, offshore energy operators, telecoms needing backhaul, and governments, priced and provisioned more like a dedicated circuit.

A 2023 partnership lets cruise ships combine Starlink’s speed with O3b mPower’s steady capacity depending on what a ship needs at a given moment. Sunday’s completed 13 satellite constellation effectively finishes the medium orbit half of that pairing, years after.

Sunday’s mission was already a something on SpaceX’s manifest well before O3b mPower entered the picture. This flight marked its 29th trip to orbit, a history that includes two crewed Axiom missions, the European Space Agency’s Euclid telescope and 22 separate Starlink batches. SpaceX has landed boosters on the droneship A Shortfall of Gravitas so often that Sunday’s touchdown attempt, if it went as planned, was set to be the 661st successful Falcon booster landing to date.

For a company that pushed the Starlink constellation past 11,000 satellites back in August, almost entirely through bulk launches from California, Sunday’s flight was a reminder that SpaceX’s schedule still has room for someone else’s satellites too. SES gets a finished network built for a narrower set of customers, and Falcon 9 gets one more line on an already long resume.

Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.


Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.

The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.

Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.

The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.

Tesla plans big safety improvements for Full Self-Driving v15

Published

on

Credit: Tesla

Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.

Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.

In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.

The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.

The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.

Tesla is rolling out a new FSD version with a massive safety addition

Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.

Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.

A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.

European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.

Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.

Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.
