SpaceX Starlink becomes first US mega-constellation to gain FCC approval

Published

on

Sans fanfare, the Federal Communications Commission (FCC) has made SpaceX the first US-based entity authorized to launch and operate a massive broadband internet satellite constellation in Low Earth Orbit (LEO).

The Starlink constellation authorization comes a bit less than five weeks after SpaceX launched its first two prototype communications satellites as co-passengers with the Spanish PAZ imaging satellite. CEO Elon Musk confirmed that they had safely made it to orbit and were communication with ground control in Hawthorne, CA, but SpaceX’s lips have remained sealed beyond Musk’s brief mention.

Unofficially, sources in the loop were told that Musk forwarded a memo to all hands soon after launch, confirming that the Starlink prototypes had successfully sent their “Hello, world” message to ground control. In the month since launch, the Tintin twins appear to have both raised their orbits slightly, suggesting that their propulsion systems were/are at least partially functional. Per FCC licenses for the experimental satellites, the Tintins are expected to eventually raise their orbits from 500km to approximately 1100km over the course of testing, maneuvering that would require their SpaceX-designed ion propulsion modules to function properly.

Gwynne Shotwell, COO of SpaceX, gave an official statement on the FCC’s authorization of Starlink, reiterating the company’s awareness of a huge amount of work ahead of any operational constellation.

“We appreciate the FCC’s thorough review and approval of SpaceX’s constellation license. Although we still have much to do with this complex undertaking, this is an important step toward SpaceX building a next-generation satellite network that can link the globe with reliable and affordable broadband service, especially reaching those who are not yet connected.”

As the SpaceX’s first foray into true electric propulsion and dedicated communications satellites, not to mention an array of cutting-edge technologies (optical/laser-based interlinks, advanced antenna tech, and more) presumed to be on board, it’s fair to assume that the public silence is indicative of a heads-down work ethic while Starlink engineers and technicians get a handle on the tasks before them and learn volumes about the manufacture and operation of advanced satellites. If they were to occur, failures or serious problems with these first two prototypes would, in fact, benefit SpaceX and strengthen all future prototype testing efforts, ultimately resulting in a more successful final product and happier customers in the long term.

Although the FCC’s approval carries with it a number of conditional requirements of SpaceX, it is all but guaranteed that SpaceX will be able to satisfy those conditions and ensure that Starlink remains authorized, barring any significant and unforeseen legal challenges. Of those conditions, the most significant condition of note relates to a request for additional information from SpaceX on the company’s end-of-life and deorbit practices in order to guarantee that the constellation’s 4,000+ satellites do not become a space debris risk. The most serious threat to Starlink as it stands proposed today is the FCC’s decision to deny SpaceX a waiver for the requirement that 50% of any given LEO internet constellation must be launched six years after approval. In the case of the 4400+ satellite Starlink constellation, this would require SpaceX to launch more than 30 satellites a month for every month between now and March of 2024. Thankfully, the FCC approval acknowledges that it will reconsider SpaceX’s request for a waiver of this requirement in the future, once the design of Starlink has been finalized. 

Correction: While the FCC’s final license grant appeared to deny a waiver requested by SpaceX for the requirement of launching 50% of the constellation within six years of licensing, the FCC has in fact already reconsidered this requirement [PDF] for uniquely large constellations out of its sheer impracticality. SpaceX should thus have some added flexibility in the pace of its deployment of Starlink.

Limited internet service from SpaceX’s Starlink constellation is not expected to begin before 2020 at the earliest. The FCC’s announcement can be read in the news release here [PDF]  or in the full application approval here [PDF].

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.
