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.

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.
For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
Venture capitalist Chamath Palihapitiya has cautioned investors shorting SpaceX shares, drawing a direct parallel to the intense short-selling pressure Tesla faced in its early public years.
Responding to reports of elevated short interest in the newly public rocket, satellite, and AI company, Palihapitiya noted that similar dynamics played out with Tesla, where aggressive short sellers ultimately “went broke.”
SpaceX (NASDAQ: SPCX) went public on June 12, 2026, in the largest IPO on record, pricing at $135 per share. Shares quickly surged to an all-time high of $225.64 just days later, briefly implying a valuation exceeding $2 trillion. The stock has since retreated sharply amid valuation concerns, lockup expiration fears, and broader market dynamics.
By early August, it traded near $108–$125, representing a roughly 50 percent decline from the peak and bringing the market capitalization closer to the $1.5–1.7 trillion range. On August 4, shares closed up more than 9 percent at $125.33 ahead of earnings before facing pressure in after-hours and premarket trading.
Short interest has climbed dramatically. According to S3 Partners data widely cited in market reports, short positions reached approximately 219.3 million shares by late July, about 34 percent of the limited public float of roughly 640 million shares, and represented a notional value of around $24.6 billion.
Utilization of shares available to borrow hit 95 percent, with borrow fees rising. This level of shorting exceeded the dollar value of short bets against Tesla at the time and built rapidly ahead of two catalysts: the company’s first post-IPO earnings and an August 6 lockup expiration that could free up to 911.5 million additional shares.
CEO Elon Musk has issued warnings of his own. In mid-July, as short interest approached one-third of the float, he posted that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” reiterating his view that the company could ultimately be worth more than Earth if it achieves its goals.
On August 4, just before earnings, Musk responded to the latest short-interest data by saying, “I try to warn them, but they just double down.”
SpaceX delivered its first quarterly results as a public company after the close on August 4. Second-quarter revenue rose 92 percent year-over-year to $7.8 billion, beating consensus estimates near $6.8–6.9 billion.
The net loss narrowed to $541 million, or 9 cents per share, better than the roughly 23–24 cent loss expected. Starlink/connectivity contributed about $4.3 billion (up 66 percent), while the AI business generated $2.6 billion (up roughly 250 percent). Capital expenditures were heavy at $18.4 billion, largely tied to AI infrastructure. Management projected a $100 billion annualized revenue run rate by year-end 2026 and outlined a path toward $1 trillion in annual revenue by 2030.
The combination of Chamath’s historical reminder, Musk’s repeated alerts, and the company’s ambitious growth targets underscores the high-stakes debate surrounding SPCX. Short sellers are positioned for near-term supply pressure from the lockup, while long-term bulls point to Starlink scale, Starship progress, and AI compute expansion as reasons the bears may ultimately face the same fate as many early Tesla skeptics.
