SpaceX’s Starlink space internet gets new competitor with OneWeb satellite launch
The most viable competitor to SpaceX’s Starlink Internet constellation has completed a demonstration launch, placing the first six OneWeb satellites in a circular orbit 1000 km (620 mi) above Earth.
Designed as a constellation of approximately 650-900 satellites, OneWeb aims to provide uninterrupted Internet access across the world with a focus on affordability for those living without a basic communications infrastructure. Assuming OneWeb’s first six spacecraft operate nominally in orbit, the first phase of the company’s constellation could be completed by late 2020 or early 2021, leading to initial operations with customers actually able to access the internet through their spacecraft.

Compared to OneWeb, SpaceX’s Starlink constellation (even in its earliest phases) is dramatically more expansive, featuring anywhere from 2-7x as many spacecraft and an overall bandwidth that is likely even greater still. As a partial consequence, Starlink spacecraft will likely be more complex and expensive to mass-produce and operate. Combined with optical (laser) interlinks that could make Starlink truly revolutionary, it remains to be seen whether the costs of high-tech solutions can be outweighed by their intrinsic benefits.

Thanks to the relative simplicity and lower mass of OneWeb’s spacecraft, as well as a partnership with industry heavyweight Airbus Defence and Space and the partial completion of a Florida-based satellite factory, OneWeb undeniably has several steps up on SpaceX, at least with respect to the goal of reaching initial commercial operations as quickly as possible. SpaceX has already gained experience operating its first two demonstration satellites – known as Tintin A and B – for a full year on-orbit, but all that is known Starlink’s first operational launches is that CEO Elon Musk is dead-set on commencing deployment no later than June 2019. Meanwhile, the status of SpaceX’s production facilities is unclear, with two mid-sized buildings in Redmond, Washington known to be dedicated to the program.
An array of job posts and brief hints from primary and secondary sources indicate that the Starlink program is already heavily focused on ramping up spacecraft production after several years of development. It’s unclear if a planned second set of prototype satellites is still on the books, hinted at by Musk in the months after the first pair’s February 2018 launch debut.

Aside from the satellites themselves, prospective global internet constellation operators must face the equally critical and challenging task of developing a simultaneously high-performance and low-cost user terminal, the antenna and associated electronics that turn spacecraft signals into an accessible and reliable internet connection. SpaceX’s work in this direction has been silent, while OneWeb founder Greg Wyler recently began teasing and describing the company’s own work in that direction, hinting that his team has already arrived at a $15 antenna prototype capable of supporting 20-60 Mbps (megabits per second).

Meanwhile, the hopeful success of the company’s first launch will pave the way for the first full launch of OneWeb spacecraft, potentially as many as 32-36 at once on Arianespace’s Russian Soyuz 2 launch vehicle. OneWeb has 21 launches manifested on Soyuz 2 rockets, scheduled to occur at a more or less monthly cadence between the first operational launch and the completion of Phase 1’s 650-satellite constellation. Shortly after the first launch was completed, Arianespace CEO Stéphane Israël announced that it had struck a deal with OneWeb as the official customer for the first two launches of its Ariane 6 rocket, meant to debut as early as 2020.

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.
