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 shows what Roadster drivers will see on screen before thruster activation

Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.

Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”

The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.

Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.

That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.

The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.

The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.

Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves

Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.

Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”

The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.

Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.

The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.

Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.

The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.

Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on

Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.

Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.

On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”

Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”

The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.

Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.

How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.

Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.

Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
