Elon Musk: SpaceX’s first orbital Starship launch “highly likely” in Q1 2023

Published

on

SpaceX’s first Starship orbital launch mount (OLM) appears to have passed a busy week of stress-testing, clearing the way for the company to transport a finished Super Heavy booster to the pad.

Using the same launch mount, that Starship booster is expected to attempt to complete some of the riskiest and most challenging tests SpaceX has ever conducted at its Starbase rocket development facilities. The schedule for that testing is unclear, but after an unusually drawn-out period of qualification testing, Super Heavy Booster 7 (B7) could soon attempt a full static fire test of all 33 of its Raptor 2 engines. Either before or after that crucial test, SpaceX is also expected to install Ship 24 (S24) on top of Super Heavy B7 for Starship’s first full-stack “wet dress rehearsal.”

Ultimately, if that testing produces the results SpaceX wants to see, CEO Elon Musk says that Starship could attempt its first orbital launch as early as late February or March 2023.

Booster 7

Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.

Following its return to the OLS in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site (OLS) for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.

Ship 24

Starship prototype S24’s path has been a bit less rocky. The ship has needed some less obvious repairs, particularly right after its first tests in May 2022. Since August 2022, Ship 24 has completed three static fire tests – all seemingly successful. Most importantly, one of those tests ignited all six of S24’s Raptor engines, potentially qualifying it for an orbital launch attempt. Most recently, SpaceX completed a series of mysterious repairs, replaced and static-fired one of S24’s engines, and removed the Starship from its test stand.

With Booster 7 now awaiting installation on Starbase’s orbital launch mount and Ship 24 near-simultaneously removed from its test stand, it appears that SpaceX may attempt a different test before Super Heavy’s full static fire. Instead, SpaceX could start by stacking Ship 24 and Booster 7 and conducting a full-stack wet dress rehearsal (WDR) before shifting focus to Booster 7’s riskier static fire.

A wet dress rehearsal is a routine test conducted before a rocket launch and is generally designed to simulate every aspect of a launch save for engine ignition and liftoff. Most importantly, that involves fully filling the rocket with propellant and passing all of the checks the same rocket would need to pass to be cleared for launch. For Starship, the largest rocket ever built, a full propellant load means filling both stages with an extraordinary ~5000 tons of liquid oxygen and liquid methane propellant. SpaceX also needs to fill the rocket fast enough to keep that propellant supercool, which increases its density and overall performance.

The first full-stack WDR will thus test Starbase’s launch facilities just as much as Booster 7 and Ship 24. SpaceX has conducted many several Starship WDRs, but not with Ship 24. It’s also never fully filled a Super Heavy booster with real propellant, let alone both stages at once. It’s likely that issues will be discovered as SpaceX pushes the envelope, likely requiring multiple attempts.

OLS

In the spirit of caution, SpaceX has even taken the unusual step of stress-testing Starship’s orbital launch mount with a custom jig. In the first week of 2023, SpaceX used that jig to load pairs of the OLM’s 20 hold-down clamps with hundreds of tons of ballast, ensuring that they can withstand the immense weight of a fully-fueled Starship. Proof tests of Super Heavy B4 and B7 have likely subjected the OLM to 2000+ tons of force, but a full Starship will weigh more than double the maximum weight the OLM has experienced to date.

Plenty of risk remains and SpaceX is trading speed for caution, but this extra-cautious step has likely reduced the risk of the launch mount’s structure failing during wet-dress and static fire testing. According to Musk, SpaceX has a “real shot” at preparing Starship for a “late February” orbital launch attempt. Nonetheless, Musk also implied that a full-stack WDR and 33-engine static fire would “probably” be completed “in a few weeks” in September 2022. What is clear is that SpaceX is more committed than ever before to avoiding a catastrophic failure during Starship’s first orbital launch attempt.

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

on

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.
