SpaceX has completed the first half of its critical Crew Dragon test flight, launching the brand new spacecraft into low Earth orbit (LEO) on the back of one of its workhorse Falcon 9 rockets. The rocket performed nominally, successfully sending the human-rated vehicle on its way towards the International Space Station (ISS).

Scheduled to dock with the ISS as early as 6 am EST (13:00 UTC) March 3rd, Crew Dragon will now face the real challenge of this demonstration mission, successfully operating in orbit and autonomously docking with the ISS. Along the way, SpaceX will be flight-testing a number of technologies and systems new to the company, while also providing reams of data that will help both SpaceX and NASA determine whether Crew Dragon performed as intended and is truly ready to carry astronauts into orbit.

While this successful launch is a critical milestone for DM-1, Crew Dragon, SpaceX, and NASA, it’s hard to say there is anything particularly shocking about its successful completion. Including this launch, SpaceX has now successfully launched Falcon 9 42 times in a row since January 2017, including seven orbital launches and ISS missions with Cargo Dragon, a heavily proven spacecraft with 16 successful missions since its 2012 debut. Put simply, SpaceX has an incredibly dense volume of experience successfully launching, landing, recovering, and refurbishing orbital-class rockets and spacecraft, as well as a proven track record of success and an ability to confront and move past challenging vehicle failures.

Crew Dragon’s successful launch is no less of a major achievement, even if it was about as much of a known quantity as any other Falcon 9 mission. The real challenge ahead of the spacecraft is successfully demonstrating the efficacy of its design and operations in space, particularly while interacting and docking with the ISS. Prior to tomorrow morning, all SpaceX Dragons have berthed with the ISS, meaning that they effectively come up from underneath the ISS (a lower orbit), stop a few meters away, and are ‘grappled’ by a large robotic arm (known as Canadarm2) that also attaches the spacecraft to a docking port. If – at any point during the pre-berthing approach – Cargo Dragon were to lose control, the spacecraft would essentially fall back down the gravitational hill it had just climbed, a built-in abort that would nominally prevent the spacecraft from impacting the Station in most failure scenarios.

Crew Dragon, on the other hand, has been designed to dock with the ISS. Generally speaking, this means that the spacecraft will approach the Station side-on, as if it were a car accelerating faster than another car in the same ‘lane’. While there are many built-in points during the docking approach where Crew Dragon will halt all forward movement, the differing docking approach means that any loss of control or contact while on a vector towards the ISS could mean that it is unable to abort, significantly increasing the likelihood of an impact event in worst-case scenarios. While Crew Dragon is designed with extreme redundancy and fault-tolerance in mind, the stakes are definitively higher compared to Cargo Dragon.

Conscious of this fact, the new spacecraft will be tasked with completing a significant number of on-orbit maneuvers to verify nominal performance before allowing the autonomous vehicle to attempt a docking with the ISS. While that docking attempt is scheduled to occur as early as 6 am EST (13:00 UTC), live coverage – hosted by both NASA and SpaceX – will begin around 3:30 am EST (10:30 UTC) on Sunday, March 3rd. While these on-orbit webcasts can admittedly be rather dry compared to the thrill of launch, it will arguably be the most significant and mission-critical portion of Crew Dragon’s launch debut, alongside the spacecraft’s safe reentry and Atlantic Ocean landing and recovery.

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.
