SpaceX’s Crew Dragon has officially become the longest-lived American astronaut spacecraft ever built, beating an 84-day record set by the Apollo-era Skylab-4 mission almost half a century ago.

Crew Dragon was able to beat that record so quickly because NASA ultimately chose to cannibalize its existing Saturn rocket and Apollo CSM spacecraft expertise, production capabilities, and budget to go all-in on the Space Shuttle program. Meant to be quickly and cheaply reusable, a wide range of compromises, budget shortfalls, and design-by-committee missteps ultimately produced a Shuttle that was horrifically complex, unsafe, only partially reusable, suboptimal for most tasks, and more expensive to launch than Saturn V.

The Space Shuttle was ultimately a beast to refurbish and “reuse”, often requiring an almost complete disassembly and reassembly and extensive rework on most propulsive components. Partially due to those extreme shortcomings and a catastrophically fatal launch failure just five years after its debut, the Shuttle was never able to get anywhere close to realizing its limited but still strong potential, including a maximum orbital longevity of just two or so weeks.

As a result, NASA went from Saturn I, Saturn V, and CSM – a combination that enabled single-launch space stations, multi-month crewed spaceflights, and the Apollo Program – to the Space Shuttle, an anchor that yanked the space agency’s human agency ambitions back to low Earth orbit (LEO). In the Space Shuttle’s defense, NASA did eventually join an international initiative to build the International Space Station (ISS), a program the Shuttle supported with several dozen launches of crucial modules, components, and supplies.

However, had NASA been able to continue the Skylab program with Saturn and CSM, a space station with a habitable volume similar to the 2021 ISS could have been completed in a mere three launches, compared to no less than 30 launches to build the ISS.

Regardless, after an unfortunate and unnecessary 47-year pause, SpaceX – with NASA funding – has returned the space agency and the US to its legacy of envelope-pushing. On the heels of 20 successful uncrewed Cargo Dragon missions to and from the ISS over the last 9 years, all of which spent around a month in orbit, SpaceX’s third Crew Dragon launch has already beat the US record for crewed spacecraft longevity on orbit and is ultimately poised to double it before the mission’s end.

Crew Dragon’s Crew-1 astronauts even celebrated the milestone in orbit with (albeit virtually) Ed Gibson, one of the three astronauts that set Skylab-4’s record 47 years prior. Additionally, in a pleasing coincidence, Skylab-4 and SpaceX Crew-1 nearly launched on the same day, meaning that tomorrow (February 8th) is the true 47th anniversary of the Skylab-4 mission’s reentry and splashdown.

All told, all operational Crew Dragon missions – of which Crew-1 is the first – are scheduled to spend approximately 180 days in orbit between launch and reentry. As the first US spacecraft (and first private spacecraft) to attempt such a long spaceflight, there is obviously some uncertainty and no guarantee that this first try won’t be cut short, but odds are in SpaceX’s favor that Crew Dragon capsule C207 will depart the ISS without issue and safely return its four-astronaut crew back to Earth sometime in May 2021.

Tesla Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper

Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.

Published

Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.

Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.

The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.

Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.

The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”

That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.

The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.

Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
