SpaceX Dragon spacecraft caught by robotic space station arm for the last time
On March 9th, SpaceX’s CRS-20 Cargo Dragon completed an uneventful journey to the International Space Station (ISS), where the spacecraft was successfully captured giant robotic arm for the last time.
Barring several major surprises, Dragon’s March 9th capture was the last time a SpaceX spacecraft berthed with a space station for the foreseeable future – possibly forever. Referring to the process of astronauts manually catching visiting vehicles and installing them on an airlock with a giant, robotic arm, berthing is a much younger technology than docking and was developed as an alternative for a few particular reasons. Perhaps most importantly, the Common Berthing Mechanism (CBM) ports used by Cargo Dragon, Cygnus, and HTV spacecraft are more than 60% wider than standard docking ports. In other words, spacecraft that berth can transport substantially larger pieces of cargo to and from the space station.
More significantly, however, the CBM standard came about in large part due to the decision to assemble the ISS out of 16 pressurized segments, each separately launched into orbit. Measuring about 1.25m (4.2 ft) wide, the CBM ports that connect most of the space station’s 16 livable segments make the ISS far more practical for the astronauts that crew it, while also allowing for larger hardware to be moved between each module. With Crew Dragon, design requirements meant that SpaceX had to move from berthing to docking, a trait SpaceX thus carried over when it chose to base its Cargo Dragon replacement on a lightly-modified Crew Dragon design.
Now verging on routine, Cargo Dragon capsule C112 began its final approach to the International Space Station on March 9th, pausing at set keep-out zones while SpaceX operators waited for NASA and ISS approval to continue. After several stops, Dragon arrived at the last hold point – some 10m (33 ft) away from the station – and NASA astronaut Jessica Meir manually steered Canadarm2 to a successful capture, quite literally grabbing Dragon with a sort of mechanical hand.
At that point, Dragon – like a large ship arriving in port with the help of tugboats – is in the hands of external operators. At the ISS, Canadarm2 essentially flips itself around with Dragon still attached, carefully and slowly mating the spacecraft with one of the station’s free berthing ports. Unlike docking ports, the active part of a berthing port is located on the station’s receiving end, where electromechanical latches and bolts permanently secure the spacecraft to the station and ensure a vacuum seal.
Finally, once berthing is fully complete, ISS astronauts can manually open Dragon’s hatch, giving them access to the two or so metric tons (~4000 lb) of cargo typically contained within. All told, the process of berthing is relatively intensive and expensive in terms of the amount of time station astronauts and NASA ground control must spend to complete a single resupply mission. From start to finish, excluding training, berthing takes a crew of two station astronauts some 9-12 hours of near-continuous work from spacecraft approach to hatch open.
One definite benefit of the docking approach Crew Dragon and Cargo Dragon 2 will use is just how fast it is compared to berthing. Because docking is fundamentally autonomous and controlled by the spacecraft instead of the station, it significantly reduces the workload placed on ISS astronauts. Crew members must, of course, remain vigilant and pay close attention during the critical approach period, particularly with uncrewed Cargo Dragon 2 spacecraft. However, the assumption is always that the spacecraft will independently perform almost all tasks related to docking, short of actually offloading cargo and crew.
For now, CRS-20 will likely be SpaceX’s last uncrewed NASA cargo mission for at six months. CRS-21 – Cargo Dragon 2’s launch debut – is currently scheduled no earlier than (NET) Q4 2020. Nevertheless, Crew Dragon’s next launch – also its astronaut launch debut – could lift off as early as May 2020, just two months from now. With both SpaceX’s crew and cargo missions soon to consolidate around a single spacecraft, the odds are good that Dragon 2 will wind up flying far more than Dragon 1, and the start of its increasingly common launches is just around the corner.

Elon Musk’s next Uranium in Uranus merch is Boring Company’s weirdest tease yet
Elon Musk teased a glowing new Boring Company merch idea, complete with a Geiger counter.
Elon Musk teased the next piece of Boring Company merchandise on X Saturday, and it is exactly as unserious as fans of the company’s product history have come to expect. “The next @boringcompany merch will put Uranium in Uranus,” Musk wrote in a thread posted early Saturday morning. He followed up by explaining that the item would glow in the dark, “because otherwise how could you find it,” and that a Geiger counter would be sold separately as “an optional strap-on.”
Musk closed the thread with a line that doubles as a mission statement for the tunneling company’s merchandise arm: “It’s not easy coming up with something that is both outrageously unsellable and yet extremely popular.”
The Boring Company has built a small but consistent side business out of novelty items that start as jokes and end up selling out. The company’s Not-a-Flamethrower raised roughly $10 million in a few days back in 2018, moving all 20,000 units it produced. Its Burnt Hair perfume, priced around $100 a bottle, sold out fast enough that scalpers were flipping units on eBay for ten times the retail price. Boring Bricks, made from tunneling spoil, followed the same playbook of teasing a product on X months before it became real.
Musk has not said what the actual item will be, only that it involves uranium and glows in the dark. Given the pattern, that vagueness is probably intentional. Past merch announcements have started as one-line jokes and taken weeks or months to turn into an actual product listing on the company’s site, and there is no guarantee this one follows through at all.
The timing lines up with a period of real momentum for the Boring Company outside of the joke merchandise. The company said last week it plans to double the number of operational stations on its Vegas Loop by the end of the year, a target tied to a hiring push for drivers and operations managers. Prufrock-5, one of the company’s tunnel boring machines, also just wrapped a test tunnel in Bastrop, Texas, and is expected to relaunch on its next assignment in November.
Whether the uranium joke turns into an actual product remains to be seen. Musk’s post did not include a price, a shipping date, or even a name for the item, which has historically meant a Boring Company website page goes up quietly, password protected, sometime before an announcement.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded
NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.
NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.
SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.
Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.
Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.
