SpaceX CEO Elon Musk says Starlink launch will reuse Falcon Heavy’s fairing
SpaceX CEO Elon Musk has revealed that the company successfully recovered both Falcon Heavy Flight 2 fairing halves intact and plans to reuse them this year on an operational Starlink launch.
This will be SpaceX’s first attempt to reuse Falcon payload fairings, a capability that could ultimately save up to 10% – around $6M – and countless production time per launch. Intriguingly, the Falcon Heavy fairing halves were recovered without the use of dedicated recovery vessel Mr. Steven – the vessel has been out of commission for months after an accident ripped off two of its four arms. Instead, the fairing halves parasailed to a soft ocean landing where SpaceX recovery experts aboard GO Searcher and GO Navigator carefully extracted both halves from the surface of the Atlantic. In order to reuse the fairing halves, SpaceX will need to somehow solve – if they haven’t already – the challenge of cleaning contaminated fairings.
How To Clean Your Fairing
The challenge of reusing payload fairings that have been some combination of immersed and thoroughly coated with salt water is by no means an easy one, evidenced primarily by the fact that no company or space agency has yet to try. As a temporary part of a rocket’s uppermost stage, every kilogram of weight present on the fairing can have an almost equally deleterious effect on that same rocket’s ability to place payloads in orbit. This is why the added complexity of additional deployable fairing mechanisms is universally accepted – by jettisoning fairings as soon as possible, rockets are able to carry significantly more payload to a given orbit.
This means that adding even more weight and complexity to fairings – optimized to be extraordinarily light for their often massive sizes – is avoided with extreme prejudice. This is the problem SpaceX faces in its quest to reliably recover and reuse fairings – how does one take fragile objects landing in the middle of the ocean after traveling no less than two kilometers per second (~1.2 mi/s) at apogees upwards of 100 km (62 mi) and prevent them from being destroyed, all while keeping them as light as possible?
SpaceX’s solution was to attach GPS-guided parafoils to each fairing half, as well as cold gas thrusters that allow the halves to orient themselves and remain stable between separation and parafoil deployment. Part two of that solution was to quite literally catch those floating halves out of the air with a giant, speedy boat outfitted with an equally giant net held up by four arms. Despite 5+ catch attempts and many, many controlled drop tests, that vessel – Mr. Steven – has never managed to successfully catch a Falcon fairing half. In early 2019, SpaceX moved the ship from California to Florida due to a launch drought facing the company’s West Coast launch facilities. Less than two weeks after arriving in Florida, an unknown accident resulted in the vessel losing both its net and two of its four arms to the sea, and Mr. Steven has since remained inactive – aside from infrequent trips out and about – in Port Canaveral.
Judging from CEO Elon Musk’s twofold declaration that SpaceX will now reuse its first Falcon fairings without any involvement from Mr. Steven, it’s safe to say that success will sadly bring about the end of the leased fairing recovery vessel’s utility to SpaceX. However, there is a chance that this is not the case.
The fact that SpaceX is choosing to reuse a partially waterlogged fairing for the first time on an internal Starlink internet satellite launch suggests that whatever the solution may be, it may not be compatible – or at least kosher – with current industry standards. All prior reusability milestones have been tested on commercial launches after some sort of private agreement with the customers involved, including the first Falcon 9 booster reuse and the first instances of the same booster being launched for the third time. This is likely not fair to SpaceX or its excellent customers, though. The simpler explanation is that testing unproven technologies and hardware solutions on internal launches fundamentally minimizes the risk conveyed to paying customers that likely can’t afford to lose their spacecraft.
There remains one additional explanation: SpaceX’s solution for reusing waterlogged fairings is, in fact, too immature or is an unacceptable risk of contamination for customers relative to industry standards of design. Instead, SpaceX may have chosen to build some sort of contamination resistance into the clean-slate design of its Starlink satellites, something that would be impractical to expect of customers who have spacecraft that are either already designed or built. Redesigning – let alone rebuilding – complex systems is an extremely costly endeavor. However, wide-reaching changes are far easier to implement when starting from a functionally blank page, exactly where SpaceX is with its first-generation Starlink satellites. As such, SpaceX may have decided to do just this after it realized that catching fairings could be far harder than expected and would thus remain a major bottleneck for Starlink launches if left unsolved.
Finally, it’s unclear if Musk is referring to the very first operational Starlink launch – scheduled as early as May 2019 – or an additional follow-on mission later this year. Refurbishing and reflying fairings for the first time in just one month would be an extremely impressive achievement but may also be an impractical schedule for pathfinder technology development. For now, this serves as a reminder that SpaceX’s first operational Starlink launch is scheduled one month from now.

SpaceX set to launch Axiom’s mission for diabetes research on the ISS
Axiom’s Ax-4 will test CGMs & insulin stability in microgravity—potentially reshaping diabetes care for Earth & future astronauts.
Axiom Space’s Ax-4 mission is set to launch on a SpaceX Falcon 9 rocket. Ax-4 will advance diabetes research in microgravity, marking a milestone for astronaut health.
Axiom Space’s fourth crewed mission is scheduled to launch with SpaceX on May 29 from NASA’s Kennedy Space Center in Florida. The Ax-4 mission will carry a diverse crew and a record-breaking scientific payload to the International Space Station (ISS).
The Ax-4 crew is led by Axiom’s Peggy Whitson and includes Shubhanshu Shukla from India, Sławosz Uznański from the European Space Agency, and Tibor Kapu from Hungary. The mission represents firsts for India, Hungary, and Poland, with Uznański being Poland’s first astronaut in over 40 years.
Ax-4 will conduct nearly 60 science investigations from 31 countries during its two-week ISS stay. A key focus is the “Suite Ride” initiative, a collaboration with Burjeel Holdings to study diabetes management in microgravity.
“The effort marks a significant milestone in the long-term goal of supporting future astronauts with insulin-dependent diabetes (IDDM), a condition historically deemed disqualifying for spaceflight,” Axiom noted. The mission will test Continuous Glucose Monitors (CGMs) and insulin stability to assess their performance in space.
Axiom explained that testing the behavior of CGMs and insulin delivery technologies in microgravity and observing circadian rhythm disruption could help diabetes experts understand how CGMs and insulin pens can improve diabetes monitoring and care in remote or underserved areas on Earth. The research could benefit diabetes management in isolated regions like oil rigs or rural areas.
The mission’s findings on insulin exposure and CGM performance could pave the way for astronauts with diabetes to safely participate in spaceflight. As Axiom and SpaceX push boundaries, Ax-4’s diabetes research underscores the potential for space-based innovations to transform healthcare on Earth and beyond.

EU considers SES to augment Starlink services
The EU considers funding SES to support Starlink. With MEO satellites already serving NATO, SES could be key in Europe’s space autonomy push.
European satellite company SES is negotiating with the European Union (EU) and other governments to complement SpaceX’s Starlink, as Europe seeks home-grown space-based communication solutions. The talks aim to bolster regional resilience amid growing concerns over reliance on foreign providers.
In March, the European Commission contacted SES and France’s Eutelsat to assess their potential role if American-based Starlink access for Ukraine was disrupted. The European Commission proposed funding EU-based satellite operators to support Kyiv. Ukraine is considering alternatives to Starlink over concerns about Elon Musk’s reliability.
Arthur De Liedekerke of Rasmussen Global warned, “Elon Musk is, in fact, the guardian of Ukraine’s connectivity on the battlefield. And that’s a strategic vulnerability.” However, SpaceX’s Starlink constellation is leagues ahead of any competition in the EU.
“Now the discussions are much more strategic in nature. They’re much more mid-term, long-term. And what we’re seeing is all of the European governments are serious about increasing their defense spending. There are alternatives, not to completely replace Starlink, that’s not possible, but to augment and complement Starlink,” SES CEO Adel Al-Saleh told Reuters.
SES operates about 70 satellites, including over 20 medium Earth orbit (MEO) units at 8,000 km. The company provides high-speed internet for government, military, and underserved areas. It plans to expand its MEO fleet to 100, enhancing secure communications for NATO and the Pentagon.
“The most significant demand (for us) is European nations investing in space, much more than what they did before,” Al-Saleh said.
Competition from Starlink, Amazon’s Kuiper, and China’s SpaceSail, with their extensive low-Earth orbit constellations, underscores Europe’s push for independence.
“It is not right to say they just want to avoid Starlink or the Chinese. They want to avoid being dependent on one or two providers. They want to have flexibility,” Al-Saleh noted.
SES’s discussions reflect Europe’s strategic shift toward diversified satellite networks, balancing reliance on Starlink with regional capabilities. As governments ramp up defense spending, SES aims to play a pivotal role in complementing global providers, ensuring robust connectivity for military and civilian needs across the continent.

Amazon launches Kuiper satellites; Can it rival Starlink?
With 27 satellites in orbit, Amazon kicks off its $10B plan to deliver global broadband. Can Bezos’ Kuiper take on Musk’s Starlink?
Amazon’s Project Kuiper launched its first 27 satellites on Monday, marking the start of a $10 billion effort that could compete with SpaceX’s Starlink with a global broadband internet network.
Amazon’s Kuiper satellites launched aboard a United Launch Alliance Atlas V rocket from Cape Canaveral, Florida. Project Kuiper’s recent launch is the initial step toward deploying Amazon’s 3,236 satellites for low-Earth orbit connectivity. Amazon’s satellite launch was initially set for April 9 but was delayed due to bad weather.
Now that the Kuiper satellites have been launched, Amazon is expected to publicly confirm contact with the satellites from its mission operations center in Redmond, Washington. The company aims to start offering Kuiper services to customers later this year. Project Kuiper was unveiled in 2019 and targets consumers, businesses, and governments who need reliable internet service, similar to Starlink.
Amazon has a deadline from the U.S. Federal Communications Commission to deploy 1,618 satellites by mid-2026. Analysts suggest the company may require an extension to its Kuiper satellite deployment deadline due to the project’s year-long delay from its planned 2024 start.
United Launch Alliance could conduct up to five more Kuiper missions this year, according to ULA CEO Tory Bruno. Amazon noted in a 2020 FCC filing that Kuiper services could begin with 578 satellites, initially covering northern and southern regions.
Kuiper’s launch pits Amazon against SpaceX’s Starlink and telecom giants like AT&T and T-Mobile, with a focus on underserved rural areas.
“There’s an insatiable demand for the internet,” Amazon Executive Chairman Jeff Bezos told Reuters in January. “There’s room for lots of winners there. I predict Starlink will continue to be successful, and I predict Kuiper will be successful as well.”
Global interest in satellite alternatives is rising. Ukraine is exploring Starlink alternatives with the European Union (EU), driven by concerns over Elon Musk. Germany’s military, Bundeswehr, also plans its own constellation to ensure independent communications. However, like Amazon’s Kuiper Project, EU options lag behind Starlink.
Amazon’s consumer expertise and cloud computing infrastructure give Kuiper a competitive edge despite Starlink’s market lead. As Kuiper ramps up launches, its success could reshape broadband access while challenging SpaceX’s dominance in the satellite internet race.
