SpaceX’s backup Dragon launch pad on track for 2023 debut

Published

on

SpaceX has begun building a backup launch pad for its Cargo and Crew Dragon spacecraft and says the facility could be ready for use as early as fall 2023.

Reuters first revealed those plans in June 2022. They arose because NASA reportedly told SpaceX it was worried that the company’s first Florida Starship launch site – colocated at the only pad currently able to launch SpaceX Dragon spacecraft – could add too much risk. In September 2022, NASA and SpaceX acknowledged plans to modify LC-40 for Dragon launches and indicated that both parties had decided to proceed.

Four months later, SpaceX and NASA have provided another press conference update. Officials confirmed that construction is already partially underway and reported that LC-40 could be ready to support its first Dragon launch less than a year from now.

Because Boeing’s comparable Starliner capsule is years behind schedule and still unqualified to launch humans, NASA has relied almost exclusively on SpaceX’s Crew Dragon to launch its astronauts to the International Space Station (ISS) since 2020. Starliner should be ready to supplement Crew Dragon’s operational astronaut launches by the end of 2023 or early 2024, alleviating some of that pressure.

NASA, however, chose to develop two spacecraft to guarantee that one spacecraft would likely be available if the other was grounded for any reason. Adding the possibility that a giant, new, experimental rocket (Starship) could potentially halt all SpaceX Dragon launches in one fell swoop was apparently one bridge too many for the agency.

SpaceX’s answer to the problem was about as simple, elegant, and cheap as possible. The company has two operational Falcon launch pads in Florida, and it proposed to modify the second pad. SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad is located on a secure military base and has an even longer history of successful Falcon 9 launches than Pad 39A. It also appears that its layout will allow SpaceX to add a Dragon access tower without requiring major redesigns or months of downtime.

LC-40 is SpaceX’s most productive launch pad by far, and the company intends to launch up to 100 times in 2023. It’s thus crucial that the pad remains as active as possible as it’s modified – a major challenge. A combination of luck and the fact that the launch pad is already operational is the only reason that’s possible.

Modifying SpaceX’s busiest pad

In theory, SpaceX needs to do relatively little to enable Dragon launches out of LC-40. Dragon spacecraft are processed for flight at a separate facility and only head to the pad once they’re ready to be attached to a Falcon 9 rocket. The biggest modification LC-40 needs is a launch tower, but SpaceX ironically has experience building giant towers in sections – and offsite – through Starship.

LC-40’s Dragon access tower requires far less complex plumbing and should be smaller and easier to prefabricate and assemble. Regulatory documents indicate that the new tower will stand 81 meters (265 feet) tall – almost a third shorter than the 110-meter-tall tower SpaceX modified at Pad 39A for the same purpose. LC-40 will also need a swinging access arm to connect the tower to Dragon’s hatch. That arm can also be constructed offsite, further reducing the amount of downtime required.

The most disruptive modifications may involve LC-40’s transporter/erector (T/E) device, which rolls Falcon 9 out to the pad, raises it vertical, holds it down with giant clamps; and hosts a maze of plumbing that fuels, pressurizes, and powers the rocket. The top of LC-40’s T/E is fitted with a brace designed to support Falcon payload fairings. In comparison, 39A’s T/E was designed with swappable ‘heads’ that allow SpaceX to switch between Dragon and fairing configurations in a matter of days. The top of LC-40’s T/E also appears to be somewhat removable, but SpaceX may still have to halt launches for a few weeks to get the T/E up to spec and modified for Dragon.

SpaceX says that LC-40 will be ready to support its first Dragon launch as early as fall (Q4) 2023. Its first Dragon mission will carry cargo to the ISS, meaning that the tower, arm, and pad will not need to be immediately human-rated. In theory, SpaceX could even launch Cargo Dragon 2 from LC-40 without a tower or arm, as the only purpose of the tower during uncrewed missions is to load volatile cargo at the last possible second. SpaceX could even revert to a practice that dates back to its original Dragon 1 spacecraft and devise a method to late-load cargo while Falcon 9 and Dragon are still horizontal.

The tower and access arm are only essential for Crew Dragon launches, during which astronauts must board the spacecraft a few hours before liftoff. More importantly, the same arm and tower would be used to escape Dragon and Falcon 9 in case of a minor emergency. NASA requires an escape (egress) system to human-rate a launch pad and rocket. SpaceX met that requirement at Pad 39A with a “slidewire basket” system that carries astronauts to a concrete bunker several hundred feet away from the rocket. Before LC-40 can be human-rated, SpaceX will likely need to build the same basket-and-bunker system or come up with a viable alternative.

Once complete, SpaceX will have two pads capable of supporting all Crew and Cargo Dragon launches. With that redundancy in place, NASA should be far more open to regular launches of SpaceX’s next-generation Starship rocket out of Pad 39A. Access to multiple pads will likely be essential for Starship to complete NASA’s Human Landing System (HLS) contracts, which will culminate in the giant rocket sending humans back to the Moon for the first (and second) time in half a century in the mid-to-late-2020s.

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

By

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.
