SpaceX nails 50th rocket booster landing ahead of Crew Dragon takeover

On its fifth launch of 2020, SpaceX has nailed its 50th Falcon rocket booster landing and sent Cargo Dragon (Dragon 1) en route to the International Space Station (ISS) on its final mission, paving the way for Crew Dragon’s imminent takeover.

At 11:50 pm EST (4:50 UTC), a flight-proven Falcon 9 booster and twice-flown Cargo Dragon spacecraft lifted off from SpaceX’s LC-40 Cape Canaveral Air Force Station (CCAFS) launch pad, sending the Dragon 1 spacecraft on its third and final orbital launch. Things went as planned and the booster nailed its second landing, coming to a rest at Landing Zone-1 (LZ-1), while Falcon 9’s second stage successfully placed Dragon in orbit and deployed the vehicle. Now safely in orbit with both solar arrays deployed, Cargo Dragon will use built-in maneuvering thrusters to tweak its orbit, ultimately rendezvousing with space station no earlier than the morning (EDT) of March 9th.

Hopefully wrapping up a decade of success, the CRS-20 mission will be SpaceX’s last under NASA’s Commercial Resupply Services (CRS) Phase 1 contract, marking Cargo Dragon’s 20th successful space station rendezvous and 19th operational resupply mission. Over those 19 CRS missions, SpaceX – once CRS-20 has safely berthed – will have delivered nearly 45 metric tons (100,000 lb) of cargo to the space station and returned another 31 metric tons (>70,000 lb) to Earth, remaining the only operational spacecraft capable of doing so. While Dragon 1 will cease operations after capsule C112’s planned reentry and splashdown sometime next month, the vast wealth of expertise SpaceX has derived has already been funneled directly into Crew Dragon (Dragon 2), its successor.

Carrying about 2050 kg (4500 lb) of cargo, Cargo Dragon capsule C112 and its expendable trunk section will spend about a month in orbit after berthing with the space station this Monday. The mission may be the last time in history a SpaceX spacecraft berths with the International Space Station, a process that the Dragon 2 spacecraft will soon replace outright once it takes over. Instead of berthing, which refers to the process of astronauts manually ‘grappling’ a visiting vehicle with the space station’s massive robotic arm, SpaceX’s next-generation spacecraft relies on docking, meaning that it does all the work itself.

Docking is thus somewhat riskier and more technically challenging, but it also requires far less input from the station’s crew and can be done almost entirely autonomously, further simplifying the rendezvous process. Once it gets to that point, SpaceX’s massive Starship spacecraft will likely rely on the same docking technology if or when it comes time for it to mate with the ISS – the vehicle is simply too big for anything else.

A slightly tweaked version of Crew Dragon, SpaceX’s future Cargo Dragon 2 spacecraft will replace its human passengers with the same supplies Cargo Dragon currently ferries to and from the ISS. According to Vice President of Build and Build Reliability Hans Koenigsmann, SpaceX has already begun building its first Cargo Dragon 2 spacecraft back at its Hawthorne, California headquarters. That vehicle’s launch debut is scheduled no earlier than (NET) “fall” 2020 and will support CRS-21, SpaceX’s first NASA resupply mission under its CRS Phase 2 contract.

Cargo Dragon 2’s “launch debut” should thankfully be quite the non-event. Crew Dragon – nearly identical – will have hopefully flown at least two (and perhaps three) orbital missions to the space station by then, dramatically reducing risk. The spacecraft will also use Falcon 9, currently classed as one of the world’s most reliable launch vehicles. CRS-20 marked the rocket’s 54th consecutively successful launch, as well as SpaceX’s 50th successful booster landing since December 2015.

B1059 touched down for the first time on December 5th, 2019, coming to a rest on drone ship Of Course I Still Love You (OCISLY). 91 days later, B1059 completed its second launch and landing (CRS-20). (SpaceX)

For now, though, Cargo Dragon C112 still needs to make its way uphill to rendezvous with the ISS for the final time. Stay tuned for updates on the spacecraft’s last orbital mission.

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.
