SpaceX and Inspiration4 creator Jared Isaacman have announced the Polaris Program, an initiative designed to carry the torch forward from Inspiration4 with even more ambitious private astronaut launches.

In September 2021, four astronauts became the first all-private crew to launch into orbit on a mission known as Inspiration4. First and foremost, I4’s goal was to uplift St. Jude’s Children’s Hospital and raise money for the fight against childhood cancer. It undeniably succeeded in that regard, raising almost a quarter of a billion dollars – about half of which came from public donations. The mission also catapulted SpaceX into the spotlight and appeared to mark the very beginning of the company’s private human spaceflight ambitions.

Combined with a separate program from Axiom Space, which has already booked four fully private astronaut missions to the International Space Station (ISS), the creation of the Polaris Program appears to confirm as much.

SpaceX now has six private Crew Dragon launches scheduled within the next few years. Polaris adds at least two missions, beginning as early as Q4 2022. Known as Polaris Dawn, the mission will be Crew Dragon’s second free-flyer mission after Inspiration4, meaning that the spacecraft will fly on its own for the full five-day duration. That gives SpaceX and the Polaris team far more freedom, freedom that they plan to take advantage of.

SpaceX aspires for Polaris Dawn to be the highest Earth orbit humans have traveled to since the 1960s and the furthest humans have been from the planet since the 1970s. NASA’s Apollo missions, which sent humans to the Moon, hold the all-time record, which Polaris Dawn will barely scratch the surface of. But in Earth orbit, the record – 1368 kilometers (850 mi) – was set by Gemini XI in September 1966.

With a drone ship landing for the booster, Falcon 9 is officially capable of launching around 12 metric tons (26,000 lb) to a circular 1400 km (870 mi) orbit. For unknown reasons, SpaceX and NASA have never acknowledged Crew Dragon’s mass at liftoff, but the first uncrewed vehicle weighed around 12 tons when it docked with the ISS. As such, it’s likely that Crew Dragon weighs at least 13 tons with a full crew of four astronauts. It’s possible that SpaceX can reduce Dragon’s mass or eke out more performance from Falcon 9 with a more aggressive booster landing further downrange, allowing the Polaris Dawn crew to narrowly beat the Gemini XI record.

If SpaceX went as far as expending a well-worn Falcon 9 booster for the mission, it’s likely that the mission could double or even triple the altitude record. If, like with Gemini XI, SpaceX launched Crew Dragon into an elliptical orbit, it could likely go even higher and easily beat the Gemini record while still recovering Falcon 9’s first stage.

Beyond the aspirational record-breaking altitude, Polaris Dawn will also debut SpaceX’s custom-built EVA (extra-vehicular activity) spacesuits, which are described as an overall upgrade to and replacement for the intra-vehicular (IVA) suits that already routinely protect NASA and private Dragon astronauts. The Polaris announcement is the first time SpaceX has publicly confirmed that it’s developing its own EVA suit. If it happens as planned, Polaris Dawn will mark the first private/commercial EVA in the history of spaceflight.

Finally, Polaris has plans for not one but three private astronaut launches. The second mission will follow in the footsteps of Polaris Dawn – likely with another Crew Dragon flight, though SpaceX and Polaris haven’t settled on a choice yet. The third mission, however, aims to be the first crewed launch of SpaceX’s next-generation Starship rocket and an essential pathfinder for DearMoon, a separate Starship launch contract that aims to send a crew of artists around the Moon as early as 2023.

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 gives the Roadster an official “Go for launch” demonstration date

Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.

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.
