To set the stage for another Dragon launch just a few weeks from now, NASA astronauts are preparing to board a SpaceX Crew Dragon for a brief flight around the International Space Station (ISS).

Orbiting roughly 400 km (250 mi) above the Earth’s surface, the ISS and its crew of seven international astronauts have just two docking ports available to manage a growing influx of SpaceX Crew and Cargo Dragon 2 spacecraft, as well as Boeing’s chronically delayed Starliner. While Starliner hasn’t flown since a near-catastrophic orbital debut in December 2019 and isn’t likely to reattempt that uncrewed flight test until the second half of 2021, SpaceX is in the exact opposite position as it prepares to sustain an unprecedented Dragon launch cadence.

One challenge of that cadence ramp – space station port logistics and availability – is now becoming clear as SpaceX nears its next Crew Dragon NASA astronaut launch.

All launched on SpaceX Cargo Dragons, including a third destroyed during Falcon 9’s CRS-7 launch failure, the International Space Station has just two perpendicular International Docking Adapter (IDA) ports – one facing space and the other facing Earth. Regardless of CRS-7’s lost port, that IDA duo was always NASA’s plan.

The ISS requires the use of a huge, robotic arm (Canadarm2) to unload unpressurized cargo from spacecraft and that arm doesn’t have the mobility to access vehicles docked to the Earth-facing IDA port, meaning that cargo spacecraft with IDA ports can really only dock on the space-facing port. Cargo Dragon 2’s use of IDA docking and the Cygnus spacecraft’s use of berthing thankfully mean that neither NASA Commercial Resupply Services 2 (CRS2) vehicle is at risk of a traffic jam.

Sierra Nevada Corporation (SNC) is set to debut the cargo variant of its Dream Chaser spaceplane as early as 2022 for annual launches and will need to share that same lone IDA port with Cargo Dragon for its (approximately) annual resupply missions. More importantly, though, Crew Dragon and Boeing’s Starliner both require the use of one of those two IDA ports to deliver astronauts to and from the ISS. Both spacecraft are also expected to leave with the same crew that launched on them, meaning that both will spend a fully six or so months in orbit on each crew rotation mission.

In general, NASA also plans to overlap all Commercial Crew Program (CCP) astronaut launches, meaning that Crew Dragon will wait for Starliner to arrive (and vice versa) before departing the ISS with its four-astronaut crew. Those use-cases and safety requirements combine to create strict, complex scheduling challenges that mean a Cargo Dragon or Dream Chaser can never be docked to the ISS during a crew handover, while also adding significant constraints to any planned private astronaut (tourist) missions to the station – of which SpaceX already has at least one.

As Cargo Dragon 2 approached the ISS, SpaceX’s Crew-1 Crew Dragon (bottom center) was easily visible for almost the entire docking. That successful arrival marked the first time two Dragons were simultaneously in orbit and docked to the ISS – a feat SpaceX is on track to repeat (albeit with two Crew Dragons) just four months later.

In the meantime, though Boeing’s Starliner is now at least 18 months behind SpaceX’s Crew Dragon on the path to launching NASA astronauts to and from the ISS, SpaceX is picking up the slack to the extent that station ‘traffic’ conditions are practically unaffected. Whereas NASA’s nominal plan was to alternate between its two redundant Commercial Crew providers before Boeing ran into huge delays, SpaceX is on track to launch Crew Dragon’s Crew-2 astronaut ferry mission as early as April 22nd.

The flight-proven Demo-2 Dragon will then rendezvous with the ISS while Crew-1’s Dragon and four astronauts are still aboard the station. Crew-1 and Crew-2 will spend about a week together before the former group boards their Dragon and heads for home. As few as six or so weeks later, SpaceX could launch its second Cargo Dragon 2 resupply mission, known as CRS-22. – This morning’s “port relocation,” which will see the Crew-1 Dragon will ‘relocate’ from the station’s Earth-facing IDA to its space-facing port, is thus necessary to free up that port for Cargo Dragon’s arrival when Crew-1 departs.

Barring major delays, SpaceX is currently on track to complete another two Crew and Cargo Dragon launches in 2-3 months, marking four Dragon missions in seven months if all goes to plan. Another three Dragon missions are firmly scheduled in 2021, potentially making for seven Dragon launches in 11-12 months if schedules hold. SpaceX’s current record – technically achieved twice in 2018 and 2019 – is five orbital Dragon missions in 12 months.

Tune in below around 6am EDT (UTC-4) to catch Crew Dragon C207’s brief 46-minute jaunt around the International Space Station (ISS) – a first for an American crewed spacecraft of any kind.

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.

Tesla’s most delayed Cybertruck feature is finally here

Tesla finally links Cybertruck Powershare with Powerwall 3 for extended home backup after years overdue.

Published

Tesla’s Cybertruck can now pair with a Powerwall 3 to keep a house running longer during an outage, a feature the company first promised when the truck launched in November 2023.

The official Cybertruck account posted the update on X Thursday: “Powerwall 3 & I can now power your house together. This extends your home backup by over 3 days, equivalent to 9 additional Powerwalls,” Cybertruck lead engineer Wes Morrill confirmed the rollout separately, calling it the first time a vehicle and a home battery have worked together this way. Powerwall 2 and Powerwall+ compatibility is still coming later this year, per both the Cybertruck account and Morrill.

Powershare itself is not new. Tesla enabled the version that lets Cybertruck power tools, appliances or another EV through its bed outlets when the truck launched in 2023. Home backup through a Powershare Gateway and Universal Wall Connector arrived in 2024, and Tesla extended that support to homes with solar the following year. What has been missing until now is Powershare working alongside an existing Powerwall, instead of functioning as a separate backup source competing for the same job.

The pairing matters because a single Powerwall home battery typically covers a home for about a day, less if usage is heavy or the outage stretches into a heat wave or freeze. A second Powerwall for more backup storage costs several thousand dollars installed. A Cybertruck instead uses a battery the owner already has, one large enough here to add roughly three more days of backup without mounting another unit or booking an installer visit. For households in wildfire, hurricane or winter storm regions where outages run past a day, that keeps the refrigerator and medical equipment running instead of shutting down.

Tesla provides Cybertruck Powershare release update

The company told owners in October 2024 that Powerwall integration was coming sometime in 2025. That date passed, and in December 2025 Tesla pushed the target to mid-2026, with Morrill explaining at the time that two grid-forming devices need to negotiate which one manages a home during an outage, and that certifying the process across multiple generations of Powerwall took longer than expected.

For owners who bought Powershare hardware expecting it to work with whatever battery setup they already had, Thursday’s update closes a gap that has shown up repeatedly in owner complaints since Cybertruck deliveries began. Tesla has also rolled out a separate Powershare grid support program in Texas, letting Cybertrucks send power back to the grid during high demand events, so the truck’s role in a home’s energy setup keeps expanding even as individual pieces of it arrive later than promised.
