SpaceX preps for Cargo Dragon, Falcon Heavy launches despite setbacks
Despite suffering the loss of the first Falcon Heavy Block 5 center core and a catastrophic failure of the first flight-proven Crew Dragon spacecraft in nearly the same week, SpaceX’s core operations continue as usual to prepare for multiple launches in the coming months.
The echoes of the past week’s failures and ‘anomalies’ will undoubtedly ring for months to come but SpaceX now finds itself in a unique situation. Despite the imminent start of a major failure investigation, it appears unlikely – at least for the time being – that it will impact the majority of Falcon 9 and Falcon Heavy launches planned for the rest of 2019. Currently on the Q2 2019 manifest are Cargo Dragon’s 17th operational mission (CRS-17), the first operational Starlink launch, Spacecom’s Amos-17 satellite, the Canadian Radarsat Constellation Mission (RCM), and Falcon Heavy’s third launch (STP-2).
Cargo Dragon – CRS-17
Following an April 20th explosion that destroyed Crew Dragon C201, SpaceX’s next launch – Cargo Dragon CRS-17 – has likely just become the most important in the near-term. Although Crew Dragon shares almost nothing directly in common with Cargo Dragon, both spacecraft still do come from the same lineage, relying on the same propellant and Draco maneuvering thrusters, as well as similar plumbing (excluding SuperDraco pods) and many of the same engineers and technicians.
On the other hand, Cargo Dragon has never suffered a catastrophic anomaly on the ground or in flight, although SpaceX has dealt with a fair share of less serious issues throughout the spacecraft’s operational life. Further, following the August 2017 launch of CRS-12, every CRS mission has launched with a flight-proven Cargo Dragon spacecraft. In fact, it’s quite likely that the CRS-12 Cargo Dragon capsule is the same spacecraft that has been refurbished for CRS-17, as it is currently the only flightworthy capsule to have only flown one orbital resupply mission.
It’s unclear which Falcon 9 booster has been assigned to CRS-17. NASA’s agreement with SpaceX for flight-proven boosters has been predicated on keeping those boosters ‘in-family’, so to speak, meaning that NASA will only accept flight-proven boosters if they have only flown NASA missions. The only booster that currently fits that bill is B1051, previously flown during Crew Dragon’s orbital launch debut on March 2nd, but B1051 has reportedly been assigned to SpaceX’s second Vandenberg launch of 2019 at the customer’s request. CRS-17 will thus likely launch on a new Falcon 9 booster (B1056). There is a chance that Crew Dragon’s catastrophic failure has severely contaminated the Landing Zone area with unburnt MMH and NTO, both of which are extraordinarily toxic to humans in even the tiniest of quantities.
Some launch-related questions may be answered in a NASA media briefing planned for 11am EDT, April 22nd. CRS-17 is scheduled to launch no earlier than 4:22 am EDT (08:22 UTC), April 30th.
Starlink, Falcon Heavy, and more
Meanwhile, the Falcon upper/second stage (S2) spotted in the tweet at the top of the article serves as evidence of preparations for launches planned in May/June, as do a duo of first stage boosters spied during their own Cape Canaveral arrivals. All that’s missing to round out a busy week of SpaceX transportation is the appearance of one or several payload fairings, although CEO Elon Musk says that the company will try to reuse Falcon Heavy Flight 2’s fairing on the first Starlink launch.
Said Starlink launch – unofficially labeled Starlink-1 – is currently scheduled for liftoff no earlier than mid-May, likely making it the SpaceX mission that will follow CRS-17. The most likely Falcon 9 S1 candidate is the thrice-flown Block 5 booster B1046, a move that would retire risk otherwise transmitted to customers. SpaceX has now flown two separate Falcon 9 boosters (B1046 and B1048) three times without major issue, meaning that the fourth flight of the same booster (and beyond) will be new territory for reuse at some level.
Beyond Starlink-1, SpaceX has the communications satellite Amos-17 and Radarsat Constellation Mission (RCM), both of which are understood to be targeting launch no earlier than (NET) early June. Finally, Falcon Heavy Flight 3 – carrying the US Air Force’s STP-2 mission – is scheduled to launch NET June 22nd, although some additional delays are probable.
From a business-as-usual perspective, the fact that Crew Dragon C201 failed during intentional testing on the ground means that it will likely be SpaceX’s least commercially disruptive failure yet. This could change for any number of reasons, depending on the conclusions drawn by the joint NASA-SpaceX investigation soon to begin, and it’s far too early to draw far-reaching conclusions. Chances are good that the impact to non-Crew Dragon launches will be minimal but only time will tell as SpaceX begins to quite literally pick up the pieces and start a deep-dive analysis of all data gathered from Saturday’s failure.

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.
