SpaceX’s Falcon Heavy eyed by Europe/Japan as ULA nails spectacular Delta Heavy launch
According to RussianSpaceWeb, SpaceX’s Falcon Heavy rocket is under serious consideration for launches of major European and Japanese payloads associated with the Lunar Orbital Platform-Gateway (formerly the Deep Space Gateway).
Currently targeting launch readiness in the mid-2020s, those heavy scientific and exploratory government payloads are eyeing Falcon Heavy at the same time as the United Launch Alliance’s (ULA) Delta IV Heavy – the most powerful operational rocket prior to FH’s debut – is busy wrapping up a scientific launch for NASA and prepping for another launch in September for its singular anchor customer, the National Reconnaissance Office (NRO).

A breathtaking mission to the sun
United Launch Alliance (ULA) has just completed the ninth successful launch of its Delta IV Heavy rocket, originally developed by Boeing in the 1990s and debuted in 2004 before the company’s launch vehicle subsidiary joined forces with Lockheed Martin’s own rocket branch. Delta Heavy’s August 12th mission saw the rocket send a small NASA payload known as Parker Solar Probe (PSP) on a trajectory that will eventually place the craft closer to the Sun than any human-made object before it. In pursuit of a better understanding of how exactly our solar system’s namesake functions and behaves, PSP will also become the fastest object ever created by humans, traveling at an extraordinary 200 km/s (120 mi/s) at the zenith of its deepest periapses (the point at which PSP is closest to the sun).
In a fitting send-off for the small heat-shielded spacecraft, Delta IV Heavy’s launch was a spectacle to behold, with clear skies and the cover of darkness combining to magnify the best of the rocket’s telltale features. Upon ignition of its three massive RS-68 rocket engines, each producing over 700,000 lb-ft of thrust, the rocket is held down for several seconds in a process that famously culminates in what appears to be self-immolation just before liftoff, a consequence of the rocket burning off excess hydrogen fuel expelled during the ignition process. Unlike Falcon 9’s dirtier kerosene-oxygen combustion, Delta Heavy’s hydrogen and oxygen fuel produce a flame that is nearly transparent, aside from a bright orange tint created by materials in each engine’s ablative (read: designed to disintegrate) nozzle.

While Delta IV Heavy has used one of its other nine successful launches for a NASA payload (a test flight of the Orion capsule), all seven remaining missions were conducted for the USAF (1) and the National Reconnaissance Office (NRO; 6), and all six remaining missions on the rocket’s manifest also happen to be for the NRO. Put simply, Delta IV Heavy would not exist today if the NRO did not have an explicit and unflappable need for the capabilities it offers. The primary downside is cost: DIVH costs at least $350 million and usually more than $400m per launch. Thankfully for ULA, the NRO has very few problems with money, and the agency’s estimated annual budget of $10 billion (2013) is more than half of NASA’s entire budget.
After Falcon Heavy’s successful debut, Delta IV Heavy’s monopoly over heavyweight NRO and USAF payloads is rapidly coming to an end, and both agencies are almost certainly attempting to equally quickly certify SpaceX’s newest rocket for critical national security space (NSS) launches. With that influx of the slightest hint of competition, Delta IV Heavy’s ~$400 million price tag starts to look rather painful in comparison to Falcon Heavy’s cost ceiling of around $150 million, potentially much less in the event that 1-3 of its boosters are recoverable. That competition likely won’t kill Delta IV Heavy, thanks entirely to the anchor support of the NRO, but it most certainly will guarantee that Delta Heavy is retired the moment ULA’s next-gen Vulcan rocket is ready to take over, likely no earlier than 2024.
Outside of the NRO, however, there is a surprising amount of interest in Falcon Heavy for interesting (and heavy) government payloads, particularly with respect to the NASA/ESA/JAXA/Roscosmos cooperative lunar space station, known as the Lunar Orbital Platform-Gateway.
Falcon Heavy enters the mix
The first payload considering Falcon Heavy for launch services is the Japanese Space Agency’s (JAXA) HTV-X, and upgraded version of a spacecraft the country developed to assist in resupplying the International Space Station (ISS). HTV-X is primarily being designed with an ISS-resupply role still at the forefront, but Russianspaceweb recently reported that JAXA is seriously considering the development of a variant of the robotic spacecraft dedicated to resupplying the Lunar Orbital Platform-Gateway (LOPG; and I truly wish I were joking about both the name and acronym).

As the name suggests, LOPG is fundamentally a shrunken, upgraded copy of the present-day International Space Station but with its low Earth orbit swapped for an orbit around the Moon. Why, you might ask? It happens that that question is far less sorted at this point than “how”, and there’s a fairly strong argument to be made that NASA is simply attempting to create a low-hanging-fruit destination for the chronically delayed SLS rocket and Orion spacecraft it routinely spends ~20% of its annual budget on. The alternatives to such a crewed orbital outpost are actually landing on the Moon and building a base or dramatically ramping development of foundations needed to enable the first human missions to Mars.

Regardless of the LOPG’s existential merits, a lot of energy (and money) is currently being funneled into planning and initial hardware development for the lunar station’s various modular segments. JAXA is currently analyzing ways to resupply LOPG and its crew complement with its HTV-X cargo spacecraft, currently targeting its first annual ISS resupply mission by the end of 2021. While JAXA will use its own domestic H-III rocket to launch HTV-X to the ISS, that rocket simply is not powerful enough to place a minimum of ~10,000 kg (22,000 lb) on a trans-lunar insertion (TLI) trajectory. As such, JAXA is examining SpaceX’s Falcon Heavy as a prime (and affordable) option: by recovering both side boosters on SpaceX’s drone ships and sacrificing the rocket’s center core, a 2/3rds-reusable Falcon Heavy should be able to send as much as 20,000 kg to TLI (lunar orbit), according to comments made by CEO Elon Musk.

That impressive performance would also be needed for another LOPG payload, this time for ESA’s 5-6 ton European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) lunar station module. That component is unlikely to reach launch readiness before 2024, but ESA is already considering Falcon Heavy (over its own Ariane 6 rocket) in order to save some of the module’s propellant. Weighing 6 metric tons at most, Falcon Heavy could most likely launch ESPRIT while still recovering all three of its booster stages.
Regardless of the outcomes of those rather far-off launch contracts, it’s clear that some sort of market exists for Falcon Heavy and even more clear that its injection of competition into the stagnant and cornered heavy-lift launch segment is being globally welcomed with open arms.

Elon Musk reveals SpaceX’s target for Starship’s 10th launch
Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.
Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.
Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.
🚨 Just wanted you to know, Starship 10’s projected test flight date, according to Grok, is August 4.
Starship’s ninth test flight took place on May 27.
August 4 is 69 days after May 27.
Do with that what you will. 🚀 https://t.co/IISpT08rIy

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.
Musk is aiming for the tenth test flight to take place in early August, he revealed on X:
Launching again in ~3 weeks
— Elon Musk (@elonmusk) July 14, 2025
This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.
IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.
IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.
The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.
The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

SpaceX’s Crew-11 mission targets July 31 launch amid tight ISS schedule
The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.
Crew Dragon Endeavour returns
Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.
“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.
For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.
The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.
The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.
Tight launch timing
Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.
“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

SpaceX launches Ax-4 mission to the ISS with international crew
The SpaceX Falcon 9 launched Axiom’s Ax-4 mission to ISS. Ax-4 crew will conduct 60+ science experiments during a 14-day stay on the ISS.

SpaceX launched the Falcon 9 rocket kickstarting Axiom Space’s Ax-4 mission to the International Space Station (ISS). Axiom’s Ax-4 mission is led by a historic international crew and lifted off from Kennedy Space Center’s Launch Complex 39A at 2:31 a.m. ET on June 25, 2025.
The Ax-4 crew is set to dock with the ISS around 7 a.m. ET on Thursday, June 26, 2025. Axiom Space, a Houston-based commercial space company, coordinated the mission with SpaceX for transportation and NASA for ISS access, with support from the European Space Agency and the astronauts’ governments.
The Ax-4 mission marks a milestone in global space collaboration. The Ax-4 crew, commanded by U.S. astronaut Peggy Whitson, includes Shubhanshu Shukla from India as the pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary.
“The trip marks the return to human spaceflight for those countries — their first government-sponsored flights in more than 40 years,” Axiom noted.
Shukla’s participation aligns with India’s Gaganyaan program planned for 2027. He is the first Indian astronaut to visit the ISS since Rakesh Sharma in 1984.
Axiom’s Ax-4 mission marks SpaceX’s 18th human spaceflight. The mission employs a Crew Dragon capsule atop a Falcon 9 rocket, designed with a launch escape system and “two-fault tolerant” for enhanced safety. The Axiom mission faced a few delays due to weather, a Falcon 9 leak, and an ISS Zvezda module leak investigation by NASA and Roscosmos before the recent successful launch.
As the crew prepares to execute its scientific objectives, SpaceX’s Ax-4 mission paves the way for a new era of inclusive space research, inspiring future generations and solidifying collaborative ties in the cosmos. During the Ax-4 crew’s 14-day stay in the ISS, the astronauts will conduct nearly 60 experiments.
“We’ll be conducting research that spans biology, material, and physical sciences as well as technology demonstrations,” said Whitson. “We’ll also be engaging with students around the world, sharing our experience and inspiring the next generation of explorers.”
SpaceX’s Ax-4 mission highlights Axiom’s role in advancing commercial spaceflight and fostering international partnerships. The mission strengthens global space exploration efforts by enabling historic spaceflight returns for India, Poland, and Hungary.
