Medtronic opens up about Elon Musk and SpaceX’s role in fight against COVID-19
Earlier this year, Elon Musk announced on Twitter that SpaceX would be working with medical device firm Medtronic to help the company produce its most advanced ventilators, which are pivotal in the battle against the pandemic. Details about the two companies’ collaboration have been quite slim since then, with Musk simply noting that SpaceX was producing valves for Medtronic.
In a recent post, Medtronic opted to share some key insights about its work with Elon Musk and his private space enterprise. The medical device maker’s story highlighted the value of Musk’s Silicon Valley-style approach to his companies, which emphasizes quick innovation that’s directed towards the development of real-world, practical solutions in the shortest time possible.
Medtronic’s Puritan Bennett 980 Ventilator Series is the company’s most advanced ventilator. It allows patients to breathe naturally through a series of innovative breath delivery technologies. It’s also fitted with a unique ventilator assistance feature that allows the machine to continue delivering ventilatory support even in the event of certain system failures. The flagship machine is built in Medtronic’s facility in Galway, Ireland, and it has become a staple in numerous hospitals.
In a typical year, Medtronic’s Galway plant could produce about 7,500 valves for its flagship ventilator. But with COVID-19 spreading across the globe, the need for ventilators increased rapidly and significantly. Medtronic promptly increased the production of its ventilators, and by mid-March, the Galway plant had raised its output by 40%. But it was not enough. Building ventilators is a complex process, after all, and the machines require advanced components that are difficult to manufacture.
One of these components is a proportional solenoid (PSOL) valve, a highly complex piece of machinery that controls the flow of air and oxygen inside the machine. The PSOL valve consists of over 50 parts, and each must be manufactured with surgical precision, with some components having tolerances as thin as a strand of hair. Medtronic’s most advanced ventilator used three of these PSOL valves per unit, and as noted by Medtronic Engineer Matt Phillips, the medical device firm was pretty much at a loss about how it could meet the increasing demand for its products.
And then Elon Musk called, and he came with a unique, interesting proposal.
Musk’s private space firm, SpaceX, which made its mark in the industry with its reusable rockets and its Crew Dragon spacecraft, offered to make PSOL valves for Medtronic. SpaceX proved to be the perfect partner for the medical device maker, as it already had a division that designs and manufactures valves for its rockets. The private space enterprise’s engineers were top-notch, and they had the technical expertise to stand up to the challenge. And with that, the two companies’ collaboration began.
In a display of its quick, Silicon Valley-style approach to problem-solving, SpaceX did not waste any time. COVID-19 was not letting up, and neither was Elon Musk’s private space enterprise. SpaceX promptly converted part of its rocket factory in Hawthorne, California to produce PSOL valves with the help of Medtronic employees. To maximize mobility and speed, the team even built a PSOL valve manufacturing line on carts. Ultimately, the SpaceX and Medtronic team achieved in months what might have otherwise taken years.
“They literally turned a rocket production area into a ventilator valve manufacturing facility almost overnight,” Phillips said.
As noted by the Medtronics engineer, SpaceX did not scrimp on its talent, with some of the engineers who worked on the Crew Dragon capsule working on the Medtronic project. Quality control was extremely high, with the valves produced at the SpaceX site undergoing rigorous testing before being shipped to Galway.
“We had their best technicians. We had their best engineers. Some of the people working on this project are the very people who just launched the first private commercial crew to the International Space Station. They brought the same kind of energy to this project that they brought to putting astronauts into space,” Phillips noted.
“When it comes down to it, these ventilators are going to save lives,” Phillips said. “So every component has to be perfect. There is no room for error, which is why we put these valves through such an intensive testing protocol,” the Medtronic engineer added.
Thanks in no small part to the quick initiative of the SpaceX team, the medical equipment company now has the capability to produce 9,000 PSOL valves for Medtronic’s flagship ventilator over the next 8 to 10 weeks. That’s about the same amount of valves that Medtronic’s Galway plant produced in 2019. The Galway facility, for its part, could now operate at five times the volume of its pre-pandemic operations.
“I have never seen anything like this in my life… This project certainly changed the way I look at production, partnership, and innovation. I know that, with the right focus and the right energy, we can take what we learned from this project and apply it to other challenges that come our way,” Phillips remarked.

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.
