NASA and SpaceX are finalizing preparations for the launch of Crew-11, the next long-duration mission to the International Space Station (ISS), currently targeted for Thursday, July 31, 2025, at 12:09 PM ET from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew members arrived yesterday at KSC, and are undergoing their final preparations for Wednesday’s launch.
The mission will send four astronauts to the ISS aboard a SpaceX Falcon 9 rocket, flying the Crew Dragon Endeavour spacecraft on its sixth voyage to orbit. The launch marks the eleventh operational crew rotation flight under NASA’s Commercial Crew Program.
Should weather or technical issues delay the liftoff, NASA and SpaceX have identified Thursday, August 1, as the primary backup launch opportunity, with a similar afternoon launch window.
Leading the Mission: Commander Zena Cardman
At the helm of Crew-11 is NASA astronaut Zena Cardman, making her first journey into space. Selected by NASA in 2017, Cardman holds degrees in biology and marine science from the University of North Carolina at Chapel Hill. Prior to her astronaut career, she conducted research in microbial ecology and geobiology—skills that align closely with her role in conducting biological experiments on the ISS.

A Veteran Returns: Mike Fincke
Seated beside Cardman in the pilot’s chair is veteran astronaut Mike Fincke. A retired U.S. Air Force colonel and flight test engineer, Fincke has already logged more than 381 days in space across two ISS expeditions and one space shuttle mission. He has also completed nine spacewalks.

Originally assigned to the Boeing Starliner program, Fincke was the backup astronaut attached the the Crew Flight Test of Starliner that resulted in the unexpectedly long stay aboard ISS for astronauts Suni Williams and Butch Wilmore.
Finke was reassigned to Crew-11 after the return of Starliner, and commercial crew schedule adjustments were made thanks to delays introduced by the CFT problems. His experience provides invaluable backup for the relatively newer members of the team, and his familiarity with long-duration spaceflight is expected to be critical in managing station operations and mentoring the crew aboard.

JAXA astronaut Kimiya Yui returns to orbit for his second flight, having previously served aboard the ISS in 2015 during Expedition 44/45. Yui, a former fighter pilot in the Japan Air Self-Defense Force, was instrumental in setting up Japan’s Kibo laboratory module during his first mission. On Crew-11, he’ll continue that legacy by supporting international science initiatives and representing Japan’s contributions to the station’s operations.

Rounding out the crew is Oleg Platonov, a first-time space traveler from Russia’s Roscosmos agency. Platonov, an aerospace engineer and former Air Force officer, was initially scheduled to fly on a Soyuz mission but joined Crew-11 under a seat-swap agreement between NASA and Roscosmos.
Despite political tensions on Earth, Platonov’s role highlights the ongoing collaboration between the United States and Russia in maintaining the ISS as a platform for peaceful international science and exploration.
Once At ISS
Once aboard the ISS, the crew will take part in Expeditions 73 and 74, diving into hundreds of research projects ranging from plant biology to space manufacturing to human health in microgravity. The mission also serves as preparation for the Artemis program, as NASA continues to build systems and experience for future lunar missions.
Dragon Endeavour, making its sixth flight, adds another chapter to its legacy as the most frequently reused crew spacecraft in NASA’s current fleet. If all goes according to plan, Crew-11 will return to Earth in April 2026 with a splashdown in the Pacific Ocean.

Tempus fugit, a lot of clocks say: “time is fleeting.” For a facility as established and enduring as Cape Canaveral Space Force Station, it might seem like forever since the first rocket launched from here. Time has flown and so have thousands of rockets and missiles from America’s premier spaceport. Truth is, CCSFS has been open “only” 75 years, but it continues to have a bright future not only today but also for the long-term future.

Tempus fugit, a lot of clocks say: “time is fleeting.” For a facility as established and enduring as Cape Canaveral Space Force Station, it might seem like forever since the first rocket launched from here. Time has flown and so have thousands of rockets and missiles from America’s premier spaceport. Truth is, CCSFS has been open “only” 75 years, but it continues to have a bright future not only today but also for the long-term future.
On July 24, 1950, a spit of land without much more than scrub grass, sand dunes, and millions of mosquitoes erupted with thunder as a two-stage rocket named Bumper 8 became the first vehicle ever launched from Cape Canaveral. At 9:28 a.m., an ignition flash and roar marked not just a technical achievement, but the start of the Space Age in America.
The Bumper 8 mission was managed by the U.S. Army, specifically the Army Ordnance Corps in cooperation with the newly formed Long Range Proving Ground (LRPG), which would later evolve into the Army Ballistic Missile Agency, ABMA. It would be ABMA and not NASA that launch the United State’s entrance into orbital launches when Explorer I flew not far from where Bumper 8 launched. Eventually, ABMA was largely folded into the United States’ fledgling space agency, NASA.
The Bumper 8 launch was the product of collaboration between military engineers, scientists—many of them veterans of World War II rocketry—and support from the Jet Propulsion Laboratory, which developed the WAC Corporal upper stage.

Technically, Bumper 8 was a Frankenstein’s monster of its era: a German V-2 missile (originally designed for wartime attacks on London and Antwerp), repurposed by American engineers, with a U.S.-built WAC Corporal sounding rocket bolted to the nose. The V-2 served as the first stage, firing for about 60 seconds and pushing the assembly to an altitude of roughly 10 miles and a speed of over 3,500 miles per hour before flaming out.
The afternoon edition of the Orlando Evening Star had coverage of the Bumper 8 launch.
Once at altitude, the WAC Corporal ignited, its smaller engine firing for another 40 seconds, pushing the second stage even higher and faster. Engineers tracking the flight from hastily assembled bunkers confirmed that the rocket reached more than 10 miles in altitude—far less than some later Bumper flights, but still a triumph for a first attempt at a brand-new site.
“I remember standing behind the blast shield, feeling the ground tremble and wondering if all our calculations would hold up,” recalled one young Army engineer present for the launch. “We had no idea what would happen—whether it would explode on the pad, veer out to sea, or fly as intended. When those engines lit, it was like watching the future arrive in a ball of fire.”
For the military brass, Bumper 8 was about more than scientific curiosity. In 1950, America’s nerves were raw. The Soviet Union had exploded its first atomic bomb less than a year before, and Cold War tensions colored every decision. The Korean War had erupted only a month prior, raising the stakes for missile and rocket research. The Pentagon needed to demonstrate that the U.S. could not only match but surpass its adversaries in missile technology.
The location for the launch—then just an isolated strip of sand and scrub known more for fishing and mosquitoes was chosen for its safety and isolation, allowing spent rocket stages to fall harmlessly into the Atlantic. The Long Range Proving Ground was as makeshift as its name suggested: a single concrete pad (Launch Complex 3), sandbag bunkers for the launch team, and primitive communications equipment. The workforce was a mixture of Army soldiers, civilian engineers, and, in the background, several German scientists brought over after World War II under Operation Paperclip.
That day, the Bumper 8’s upper stage did not set an altitude record—it was later flights in the Bumper series that would push into the edge of space. But the launch proved that Cape Canaveral could support rocketry of increasing sophistication. The Cape quickly became a focal point for military missile programs—Redstone, Atlas, and Titan, all tested here, laying the groundwork for the coming space race. Redstone would carry Alan Shepard on the first US crewed mission, Atlas would carry John Glenn to orbit and an iteration of Titan would be the booster of choice for the Gemini Program.
It wasn’t just about hardware and geopolitics. There was an undeniable thrill for those on the ground. “I had never seen anything like it—the way that thing leapt off the pad,” said Mary Pinson, the wife of an ABMA engineer. “We were sweating in the Florida heat, covered in mosquito bites, and when the rocket launched, we knew we were watching history.”

Things Are Always Changing At The Cape
Within a decade, the stakes shifted from military defense to exploration. The Soviet launch of Sputnik in 1957 galvanized the United States, leading to the creation of NASA in 1958. ABMA was all but absorbed by NASA, which in turn put its technical development center in Huntsville, where most were already working: at Redstone Arsenal. The Army and Air Force test ranges merged into what became the Eastern Test Range, and Cape Canaveral was transformed almost overnight from a sleepy fishing village into the very center of the high-tech world.
In 1962, the area grew even larger when the Launch Operations Center (LOC) was established immediately to the north of Cape Canaveral as an independent NASA field center. In November 1963, President Lyndon Johnson designated the facilities of the Launch Operations Center and Station No. 1 of the Atlantic Missile Range as the John F. Kennedy Space Center to honor the fallen president.
The Space Coast was born.
Kennedy Space Center Is Born, But A Price
The Launch Operations Center (later renamed as KSC) was founded out of necessity and ambition. In 1961, after President John F. Kennedy set the national goal to land a man on the Moon by the end of the decade, NASA realized it needed much more space for larger rockets, new facilities, and increased activity. The original launch site at Cape Canaveral—where Bumper 8 and dozens of military and civilian rockets had flown—was crowded, fragmented, and mostly run by the military. There was no room for the Vehicle Assembly Building, the giant crawlerways, or the miles of safety buffer required for the Saturn V.
NASA, with support from Congress, quickly began acquiring land west and north of the Cape. The chosen site was Merritt Island: a mix of wetlands, scrub, orange groves, small farms, fishing villages, and a handful of beach communities like Allenhurst, Shiloh, and the lively Titusville Beach. The acquisition was the largest forced relocation in NASA’s history. Over 80,000 acres (about 125 square miles) were taken—mostly through federal purchase but also through eminent domain when owners resisted. This area included the future footprint of KSC and a vast buffer zone for safety.
Compared to Cape Canaveral Space Force Station (CCSFS), Kennedy Space Center is much larger. Today, KSC spans about 144,000 acres. CCSFS is roughly 15,800 acres. That means KSC covers nearly ten times the land of CCSFS, with much of it remaining undeveloped as a buffer.
The human cost for the construction of KSC was significant. More than 1,000 families were displaced in the 1960s. The thriving black community of Allenhurst, the farming hamlet of Orsino, and most of tiny Shiloh disappeared. In total, at least 5,000 people lost their homes.
Titusville Beach—a small but beloved oceanfront community where locals and visitors came to swim, picnic, and fish—was erased. All but one of its buildings were demolished, its dunes bulldozed, and public access to the beach was cut off as NASA established a controlled area. And the building that was preserved? You may have guessed it. The Astronaut Beach House, a two-story cottage, was built in 1962 as a part of the then Neptune Beach subdivision, between where pads 40 and 41 stand today. NASA preserved and maintained the house through the years, and now its provenance is almost forgotten. There were other homes too: the town itself stretched to the other side of LC-39A.

With so much of the land needed only as a safety buffer, NASA partnered with the U.S. Fish and Wildlife Service to preserve public access to the area. In 1963, the Merritt Island National Wildlife Refuge was officially established, covering almost the entire non-operational area of Kennedy Space Center. It is a low-security zone except for launches deemed by KSC safety or security to require temporary exclusion from MINWR.
The result is an unusual coexistence: high-tech launch pads surrounded by protected wetlands, lagoons, and forests. The Refuge is now home to over 1,500 species of plants and animals, including endangered species like the Florida scrub-jay, manatees, and bald eagles. Today, MINWR hosts 2.3 million visitors annually.

The Shuttle era brought another transformation, with KSC serving as the base for over 130 shuttle flights from 1981 to 2011. The Cape weathered tragedy—like the AS-204 Apollo I fire, the loss of Challenger in 1986 and Columbia in 2003—but the NASA and its engineers adapted each time, building safer systems and deeper expertise for future space endeavours.
Today, KSC is largely the domain of SpaceX, and the company launches not only crewed missions, but also Falcon Heavy and soon, Starship Heavy from LC-39A. The company has built a large work center at Kennedy, with plans to expand greatly. NASA is staying busy too, as the VAB is still in use, this time to build the SLS rockets that are part of Project Artemis, which aims to return humans to the moon and perhaps even beyond. Instead of LC-39A, Artemis uses LC-39B, the lesser used of the two megapads.

Seventy-five years after Bumper 8’s fiery ascent, Cape Canaveral stands as a testament to American resolve and the relentless drive to explore. From makeshift pads and scavenged missiles, to the front lines of interplanetary exploration and the only place on Earth that was the starting point for vehicles now in interstellar space, the legacy of Cape Canaveral is written in thunder—one launch at a time.

Early Tuesday morning, July 15 at 5:31 AM Eastern Time, SpaceX’s Dragon capsule “Grace” brought the crew of Axiom Mission 4 (Ax-4) back to Earth with a smooth splashdown off the southern California coast. They had undocked from the International Space Station just over 22 hours earlier, at 6:15 a.m. CT on Monday, July 14. The landing marks the end of a successful 18-day journey in low Earth orbit.
Commander Peggy Whitson of the United States led the four-person team, which also included Pilot Shubhanshu Shukla of India and Mission Specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu of Hungary. Their flight marked a historic return to space for India, Poland, and Hungary—each country’s first astronaut mission in more than four decades—and the inaugural ISS expeditions for all three.
“Ax-4 illustrates the power of commercial partnerships in opening space to more nations,” said Tejpaul Bhatia, CEO of Axiom Space. “By giving Indian, Polish, and Hungarian astronauts hands-on access to the orbiting laboratory, we’re broadening global participation in human spaceflight and laying the groundwork for a dynamic low-Earth-orbit economy.”

During their stay aboard the station, the crew carried out over 60 experiments spanning life sciences, materials physics, Earth observation, and cutting-edge technology tests. Those investigations, drawn from 31 countries, underscore the mission’s international reach and its role in pushing the frontiers of microgravity research.
Beyond the lab work, the Ax-4 astronauts took part in more than 20 outreach events—engaging with students, government leaders, researchers, media outlets, and aspiring spacefarers—to share insights from their mission, spark curiosity about STEM, and demonstrate the value of global teamwork in space exploration.
Ax-4 is the fourth private astronaut flight Axiom Space has arranged to the ISS, making it the only company so far to have sent private crews into orbit. These ventures not only give governments, universities, companies, and private citizens direct access to space but also pave the way toward Axiom’s ultimate goal: building and operating Axiom Station, the first commercial space habitat.
Previous Axiom missions have carried crew members from the U.S., Spain, Israel, Canada, Saudi Arabia, Italy, Türkiye, and Sweden, in partnership with ESA. With Ax-4’s success, Axiom Space continues to demonstrate the value of international collaboration and the promise of a new era in commercial spaceflight.

July 11, 2025: it’s been over a year since the public scoping period for the FAA’s Environmental Impact Statement, and no Draft EIS or even a date for one has been announced for SpaceX’s Starship-Super Heavy project at Launch Complex 39A at KSC.
Casual onlookers may wonder if something is awry, but that’s probably not the case. The wheels of government turn slowly and often do so silently, and an announcement could come any day.
Two Separate Facilities, Two Seperate EIS
Many people who don’t live at the Space Coast don’t realize that Kennedy Space Center and Cape Canaveral Space Force Station are two adjoining but separately managed facilities. NASA operates KSC, of course, and SpaceX leases LC-39A from the government at KSC. Cape Canaveral SFS, located southeast of Kennedy, is a US Space Force Military facility and is operated by the Department of the Air Force. SpaceX leases SLC-40 at CCSFS and seeks to lease LC-37 there.
There are even gates between the two facilities, though they don’t seem to ever close. There is great cooperation between the Space Force and NASA, and they often work together when needed.
In this facilities map, the two different facilities that make up KSC and Cape Canaveral Space Force station are clearly visible. In green is KSC and in yellow is CCSFS Map: NASA
That’s important, because there are two authorities conducting two Environmental Impact Statements for two different launch pads: LC-37 and LC-39A. The former is the retired site of United Launch Alliance’s Delta IV Heavy rocket, which flew its last flight last year.

The latter, LC-39A, is of course the historic launch facility that served Apollo and STS (Shuttle) missions in its long and storied career. SpaceX has made their own history at LC-39A: the return of crew to orbit after a long gap following the end of the Shuttle program, the launch site of Falcon Heavy and other commercial spaceflight firsts.

Current Status
The EIS process for LC-39A continues to be underway. No statements otherwise have been released by any of the parties involved, so it is safe to say that work is continuing.
SpaceX is preparing the EIS under FAA supervision, analyzing the environmental impacts of proposed Starship-Super Heavy operations, including up to 44 launches per year, infrastructure construction; a Super Heavy booster catch tower, propellant systems, and stormwater/deluge ponds), and landings at LC-39A or on a droneship.
The process is evaluating changes from the 2019 Environmental Assessment (EA), which found no significant impact but did not account for the current scope of operations. The next step is the release of the draft EIS for public review and comment, followed by a final EIS and a Record of Decision.
Release Date of the LC-39A Draft EIS
There is no specific release date publicly announced for the draft Environmental Impact Statement (EIS) for SpaceX’s Starship-Super Heavy project at LC-39A at Kennedy Space Center. The Federal Aviation Administration (FAA) initiated the EIS process with a Notice of Intent published on May 9, 2024, and held public scoping meetings in June 2024.
Based on typical EIS timelines (often 12-18 months) and the FAA’s ongoing work, the draft EIS is likely to be released in mid-to-late 2025. For comparison, the draft EIS for Starship launches at Space Launch Complex 37 (SLC-37) at Cape Canaveral Space Force Station was released on June 6, 2025, after a scoping period starting in February 2024, fifteen months earlier. The LC-39A EIS Draft should come in the next 5-6 months, or roughly the same time as a final decision on LC-37 is due, according to DAF project timelines.
New Federal NEPA Rules
The FAA has issued a notice rescinding its existing National Environmental Policy Act (NEPA) implementing procedures outlined in FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, and replacing them with streamlined procedures in FAA Order 1050.1G. This change is driven by Executive Order 14154 of the President, entitled “Unleashing American Energy.”
The new order accelerates environmental reviews projects by imposing strict timelines and page limits on EISs (e.g., 2-year completion cap), expanding CATEX (Categorical Exclusion) usage, allowing combined exclusions, and promoting early collaboration to minimize delays. This aligns with the Trump Administration’s policy to expedite permitting. That could potentially benefit commercial space operators like SpaceX by shortening review periods for future licenses or modifications, thus supporting faster integration of technologies like Starship.
However, for the specific ongoing EIS for SpaceX’s Starship-Super Heavy operations at LC-39A, the new rules should not apply directly. Order 1050.1G applies only to FAA actions requiring environmental review that “commence on or after” July 3, 2025, and since the LC-39A EIS was started in 2024, the new order is moot.
Responsible Agencies
There is a mix of federal agencies responsible for completing aspects of the LC-39A EIS.
Lead Agency:Federal Aviation Administration (FAA), responsible for overseeing the EIS process and issuing a commercial launch Vehicle Operator License to SpaceX if the final decision of the EIS is to allow work on 39A to proceed.
Preparing Entity: SpaceX, tasked with preparing the EIS under FAA supervision.
Multiple Cooperating Agencies:
National Aeronautics and Space Administration (NASA): Manages KSC and leases LC-39A to SpaceX, providing oversight for space-related activities.permits.performance.gov
U.S. Fish and Wildlife Service (USFWS): Manages the Merritt Island National Wildlife Refuge, which includes KSC property, and provides expertise on wildlife impacts.permits.performance.gov
National Park Service (NPS): Oversees Canaveral National Seashore, partially within KSC boundaries, and contributes expertise on affected lands.permits.
U.S. Coast Guard (USCG): Involved due to maritime safety and airspace closures for launches.
Department of the Air Force (DAF): Coordinates due to proximity to Cape Canaveral Space Force Station and shared range.

KSCVC rendering of the newly updated Gantry at LC-39A
The Kennedy Space Center Visitor Complex has expanded its popular bus tour to include The Gantry at Launch Complex 39—a multi-level attraction nestled inside KSC that was updated and upgraded over the past several months.
Perched just 1.5 miles from LC-39A and 2.25 miles from LC-39B—the primary pads for NASA’s Artemis lunar missions—The Gantry offers a front-row seat to the agency’s current and future launch operations. Guests will find four stories of interactive exhibits, an Earth Information Center that explores how space science benefits life on our planet, and carefully preserved artifacts from NASA’s storied past.
No word has been given about launch viewing at the site. LC-39A and LC-39B are too close, of course, as there is at least a 3.5 mile exclusion area surrounding each pad and The Gantry will be too close for viewers. In the past, The Gantry has hosted spectators for launches from ULA’s pad at LC-41 and SpaceX’s pad at SLC-40 on Cape Canaveral Space Force Station and given them a point blank (relatively speaking) view of the launch equal to what the working press sees.

Static Fire Simulator

For years, The Gantry had a real flight-worthy Aerojet-Rocketdyne RS-25 engine on display — one where users could get a close view of the engines that powered the launches of space shuttle orbiters and SLS rockets. When the Artemis program got started in earnest, that display was removed, leaving a huge hole in each level of The Gantry. That has been replaced by a new Static Fire simulator.
The new simulator, unique to The Gantry, recreates the moment a rocket engine fires for a ground test. Under the guidance of a NASA engineer and an on-site AI assistant named Sōl, visitors will witness an amplified demonstration: a 30-minute countdown culminates in a dramatic eruption of noise, light and cooling fog.
Education Is A Prominent Display At The Gantry
The Gantry’s designers also emphasize education. From its vantage point, guests can gaze across the wildlife refuge’s swamps and scrublands to active launch pads at both Kennedy Space Center and Cape Canaveral Space Force Station. Interactive displays illustrate how each mission contributes to our understanding of Earth’s climate, ecosystems and natural resources.
Axiom 4 lifts off from LC-39A at Kennedy Space Center
After several delays, Axiom 4 is on its way to the International Space Station. The corporate mission, commanded by NASA veteran Peggy Whitson, lifted off at 2:31 AM Eastern Time from Launch Complex 39A at Kennedy Space Center aboard a SpaceX Falcon 9 and Crew Dragon.
In addition to Whitson, Shubhanshu Shukla, an officer in the Indian Air Force and astronaut with the Indian Space Research Organisation (ISRO), will serve as the pilot. Mission specialists include Sławosz Uznański-Wiśniewski, a project astronaut with the European Space Agency (ESA) representing Poland, and Tibor Kapu from Hungary. Notably, this mission marks the first time astronauts from India, Poland, and Hungary will visit the ISS, representing each nation’s first government-sponsored human spaceflight in over 40 years.

Notably, this mission marks the first time astronauts from India, Poland, and Hungary will visit the ISS, representing each nation’s first government-sponsored human spaceflight in over 40 years.
After a nominal ascent, Booster B1094 returned to land at Cape Canaveral Space Force Station’s LZ-1 about secen minutes and thirty nine seconds from liftoff. A few seconds later, Falcon 9’s second stage and Crew Dragon were reaching their initial orbit, which will be modified later as Axiom 4 begins chasing down ISS in earnest.
Docking is expected Thursday morning, around 7:00 AM ET.
After docking with Station, Axiom 4’s crew will begin a two-week stay aboard ISS, where they will conduct a number of experiments on behalf of their respective space agencies.
Axiom-4 Mission Objectives
Ax-4 will be a busy mission, as it is slated to conduct approximately 60 scientific experiments and activities involving participants from 31 nations, such as the United States, India, Poland, Hungary, Saudi Arabia, Brazil, Nigeria, the United Arab Emirates, and various European countries. This marks the highest number of research initiatives undertaken on an Axiom Space mission to the International Space Station (ISS) thus far, highlighting the mission’s global importance and collaborative spirit in advancing microgravity research in low-Earth orbit (LEO).
The mission places a particular emphasis on scientific endeavors led by the countries represented in the Ax-4 crew, including the United States, India, Poland (in collaboration with the European Space Agency), and Hungary. The research conducted will enhance global understanding in areas such as human health, Earth observation, and life, biological, and material sciences, reflecting the space research capabilities of the crew’s home countries.
Axiom Space is also collaborating with research organizations and academic institutions to further investigate the effects of spaceflight on the human body and to explore how space-based research can lead to improvements in health and medical treatments on Earth. The mission underscores the significance of commercial and academic partnerships, as Axiom Space spearheads the development of a global research community and a sustainable economic ecosystem in LEO. The mission also sets the stage for Axiom Station, the first commercial space station, which will provide a permanent platform for research, manufacturing, and human spaceflight.

The delayed launch of Axiom 4 to the International Space Station will have to wait a little bit longer. The company announced today that the “space agency needs additional time to continue evaluating International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory’s Zvezda service module.”
The delay is labeled as “indefinite” and no new launch target date has been announced.
The crew remains in quarantine, and the Falcon 9 and Crew Dragon planned for the flight remain in healthy condition and ready for the flight.”
The root cause of the delay is a series of micro-leaks in the Zvezda module, first detected months ago but considered under control after previous repair efforts. However, on June 14, cosmonauts aboard the ISS noted a fresh pressure signature in the aft segment of Zvezda, indicating that some seals may have degraded or reopened under flight conditions. Although the module has held pressure more consistently since the latest inspections, NASA and its Russian partners determined that more data were needed to rule out any risk to incoming crew.
On a blog update published last week, NASA detailed the troubleshooting steps taken by cosmonauts: interior surfaces were inspected, suspect seals were re-torqued, and additional leak-rate measurements were conducted. “Following the most recent repair, pressure in the transfer tunnel has been stable,” NASA wrote, “but additional time is required for Roscosmos and NASA to evaluate whether further action is necessary.” This review window now overlaps with the Monday launch opportunity, effectively ruling it out until the investigation concludes.
There are also ISS logistics to consider: Ax-4’s launch window is tightly constrained by orbital mechanics and ISS traffic. The current opportunity closes on June 30 to accommodate other scheduled resupply and crewed flights. Pushing through before fully resolving the leak could risk mission safety and station integrity, particularly given the interconnected life-support systems aboard the ISS. Axiom Space President Michael Suffredini emphasized that while commercial missions must adhere to tight timelines, safety remains the non-negotiable priority.
Axiom 4, the privately operated crewed spaceflight, now has a confirmed launch date of June 22, 2025. The mission is slated to lift off at 3:42 AM ET, from Launch Complex 39A at the Kennedy Space Center.
Originally scheduled for June 19, the flight window was pushed back as engineers addressed technical issues and concerns about the ISS leaks. The new timeline promises a mission duration ranging from 14 to 21 days to complete its planned research program.
“No one remembers launch delays, but no one ever forgets a real problem.”
–V.L. Pinson Sr., former ABMA and NASA veteran
The mission will utilize a Falcon 9 to carry the newly built Crew Dragon spacecraft C213 into low Earth orbit, marking the final Crew Dragon capsule to enter service in SpaceX’s original slate of capsules. The four-person crew—veteran astronaut Peggy Whitson commanding, Indian pilot Shubhanshu Shukla, ESA’s Sławosz Uznański-Wiśniewski, and Hungarian specialist Tibor Kapu—will conduct science and technology demonstrations aboard ISS during their flight.
Axiom Space first announced on April 3 that Ax-4 would launch no earlier than May, reflecting a cautious approach as technical reviews and ISS scheduling took shape.
By mid-April, the Ax-4 team was gearing up for a busy agenda aboard ISS with a target window of no earlier than late May. The packed schedule—includes biological experiments, materials science tests, and station maintenance tasks.
After some shifts to the right on the schedule, the mission stood ready to launch on June 10th, but weather in the ascent corridor forced mission managers to call of any launch attempt that day. The ascent corridor is the zone where Crew Dragon and its crew would land in the unlikely event of an abort. The zone extends offshore in the Atlantic Ocean from Kennedy Space all the way to Ireland, and weather inside it must be suitable — just in case.
The next day, the first launch attempt on June 11 was scrubbed after engineers detected a propellant leak in the rocket’s liquid oxygen system and called off the launch to remediate the issue.
Next, a pressure leak in the Zvezda service module on the ISS prompted NASA and Roscosmos to stabilize the module before approving further dockings, contributing to another postponement announced on June 12.
NASA, SpaceX and Axiom have now agreed on a launch attempt in the predawn hours of the first full day of summer: June 22nd. Falcon 9’s leaks have been resolved, the Space Station leak issue is now under control, and at this point, weather on the 22nd looks as though it will be acceptable for Axiom 4’s ascent into orbit.
The Indian Connection
For India’s space program, Ax-4 represents a milestone: it provides the first opportunity for an Indian astronaut to fly to ISS. Pilot and Indian Air Force Group Captain Shubhanshu “Shux” Shukla, part of ISRO’s cadre of astronauts, will carry out experiments developed by the Indian Space Research Organisation in fields ranging from microbial adaptation to muscle atrophy studies.
His flight will be the precursor to his upcoming flight aboard ISRO’s Gaganyaan-1, India’s first domestically built crewed orbital spacecraft. At 39, Shukla is a veteran test pilot, having flown everything from MiG-21s to Su-30s.

Axiom 4 will be commanded by Peggy Whitson—a former NASA chief astronaut and current Director of Human Spaceflight at Axiom Space—Ax-4 brings seasoned leadership to this venture. Whitson holds multiple Station records and is tasked with overseeing the flights to and from ISS. She has spent 665 days in space so far.
Poland and Hungary Returning To Spaceflight After 40 Years
Joining Whitson and Shukla is Sławosz Uznański, a Polish engineer and the first representative of his country in space since 1978. Back then, it was Mirosław Hermaszewski aboard a Soviet Soyuz. This time, it’s Uznański flying under the banner of the European Space Agency as a mission specialist. A former CERN engineer and ESA reserve astronaut, Uznański’s path to space was defined more by science than by spectacle. His role on Ax-4 emphasizes research, including a number of biomedical and Earth-monitoring experiments designed by Polish institutions.

Hungary, too, is returning to space after a four-decade absence. Tibor Kapu, an engineer selected under the Hungarian government’s HUNOR program, became only the second Hungarian to ever fly in space. He beat out nearly 250 applicants for the role. The first, Bertalan Farkas, flew aboard a Soviet Soyuz spacecraft in 1980.
Kapu’s mission is both technical and symbolic. “This is not just a mission for Hungary,” he said before launch. “It’s for all the small nations looking toward the stars and asking if they can be part of the next chapter.”
