SpaceX to launch replacement satellite two years after fateful Falcon 9 failure
On September 1st, 2016, SpaceX’s Falcon 9 rocket suffered a catastrophic anomaly during a static fire test, causing an explosion that completely destroyed the vehicle, the launch pad, and Spacecom’s $200M Amos-6 satellite. This ultimately triggered a months-long investigation into what CEO Elon Musk described as “the most difficult and complex failure [SpaceX has] had in 14 years.”
More than two years and 41 successful consecutive launches later, SpaceX and Israeli satellite operator Spacecom are reportedly aiming to launch Amos-6’s replacement – Amos-17 – as early as the end of May, around three months from now.

Nearly two and a half years distant, the reverberations of SpaceX’s Amos-6 Falcon 9 failure continue to reverberate loudly. Aside from demanding changes to the operational procedures used to launch Falcon 9 and forcing an extensive critical analysis of design, production, and qualification methods, SpaceX has spent countless resources pursuing an extensive redesign of the component pointed at as the primary source of the explosion that destroyed Falcon 9. Known as composite overwrapped pressure vessels (COPVs), SpaceX uses the bottles to store extremely high-pressure helium (5000+ psi, 340+ bar) to pressurize Falcon 9’s RP-1 and oxygen tanks, as well as nitrogen to power its cold-gas maneuvering thrusters.
According to a failure analysis performed by SpaceX with NASA, the USAF, the NTSB, and the FAA, it was concluded that the cause could be traced back to a complex series of events centered around those helium COPVs. Meant to be the first mission to utilize subcooled propellant and oxidizer, the extreme cold in the upper stage LOx tank caused solid oxygen to form on the outside of the COPVs located inside it. While complex, the gist was that liquid (and perhaps solid) oxygen could have formed around the outside of the COPV, potentially finding its way in between the carbon fiber wrappings, creating a buckle in the fibers, and ultimately causing fibers to break. Near the end of this process, those breaking fibers could have created a spark or breached the helium tank, instantaneously overpressurizing the upper stage and causing an explosion.
NASA’s Aerospace Safety Advisory Panel (ASAP) and NASA itself have aired concerns about those COPVs since 2016, triggering an extraordinarily comprehensive program of testing, characterization, and redesign of the COPVs SpaceX uses. They have now successfully flown on 3-4 Falcon 9 launches under the same expedited propellant loading conditions that an identical rocket will undergo in preparation for Crew Dragon launches. CEO Elon Musk spent several minutes discussing the redesigned COPVs in a May 2018 press conference and did not mince words when he described them as “by far the most advanced pressure vessel[s] ever developed by humanity.”
“The amount of testing and research that’s gone into COPV safety is gigantic. This is by far the most advanced pressure vessel ever developed by humanity. It’s nuts. And I’ve personally gone over the test design, I’ve lost count how many times. But the top engineering minds at SpaceX have agonized over this. We’ve tested the living daylights out of it. We’ve been in deep, deep discussions with NASA about this. And I think we’re in a good situation.” – SpaceX CEO Elon Musk, May 2018
NASA and ASAP concerns have since been alleviated, culminating on February 22nd with an official announcement that NASA was ready for SpaceX to conduct the first uncrewed launch of its Crew Dragon spacecraft on March 2nd. It’s thus almost poetic that customer Spacecom chose the same week to announce a target date for the Falcon 9 launch of a satellite built to replace the destroyed Amos-6, known as Amos-17. Soon after the Amos-6 disaster, Spacecom settled on a free SpaceX launch contract for a future satellite instead of an immediate $50M payout. Procured for around $160M, SpaceX is reportedly targeting the launch of the Boeing-built satellite during the week of May 27th, likely from Launch Complex 40 (LC-40) – the same pad that suffered extensive damage during the September 2016 anomaly.

Since Amos-6, SpaceX’s record of reliability has been effectively spotless and now stands at an impressive 41 consecutive successful launches, including Falcon Heavy’s February 2018 debut. Aside from the sheer volume of launches SpaceX performed in a little over two years, the company has pushed full speed ahead towards its goal of routinely reusing Falcon 9 boosters. Less than 24 months after the first commercial reuse, SpaceX has landed Falcon 9 boosters 34 times and reused them 20 times, numbers that are only likely to grow in 2019.
Set to occur shortly after the planned launch debuts of Crew Dragon and Falcon Heavy (commercially), SpaceX will hopefully be able to place Amos-17 in a healthy orbit and thus effectively retire the Amos-6 saga before the second half of 2019.

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.
