For the public, those were the first words heard from NASA astronauts Butch Wilmore and Suni Williams—the crew of the space agency’s Boeing Crew Flight Test (CFT)—since they arrived at the orbital laboratory more than one month ago for an intended eight-day stay.

The Earth-to-orbit call between crew and NASA command was live streamed on the agency’s website. The event answered appeals from members of the media, made during a previous press conference, to see the astronauts on camera as concerns with Boeing’s CST-100 Starliner—which brought them to the ISS—continue to linger.

The spacecraft is contending with two key problems: helium leaks and deactivated or underperforming thrusters. The issues are concentrated within the spacecraft’s service module, which aids in maneuvers such as docking and undocking with the ISS.

NASA and Boeing have indicated that Starliner has more than enough helium to make it home but are continuing to assess the root cause of the leaks. During a hot fire test after docking, four out of the five affected thrusters performed as expected. The fifth was deactivated for the remainder of the mission.

Williams and Wilmore recounted their trip to the space station and the moment they realized that Starliner’s thrusters were not firing at full power. They also sang the spacecraft’s praises, with Wilmore even saying he was tempted to award his first perfect rating for its handling performance.

Separately, NASA and Boeing representatives held a press conference to provide the latest on ongoing ground thruster testing at White Sands Test Facility in New Mexico. Officials again did not provide a firm return date for Wilmore and Williams. But Steve Stich, manager of NASA’s Commercial Crew program, estimated that testing could wrap up by the end of the month, after which point teams will iron out a timeline.

Engineers hope to conduct as many evaluations as possible while the semireusable spacecraft, designed to survive 10 missions, is in orbit. Starliner’s service module, the expendable component of the spacecraft, will be jettisoned and lost as it reenters Earth’s atmosphere.

Astronauts Phone Home

Williams and Wilmore on Wednesday made their long-awaited first appearance on camera since arriving at the ISS on June 6, recounting the CFT’s progress so far.

“Launch was spectacular,” Wilmore said, adding that the spacecraft performed “unbelievably well” during operational capability checks.

However, on the second day of their journey to the ISS, the astronauts could tell something was amiss. As Starliner approached the orbital lab, a total of five reaction control system (RCS) thrusters on its service module either turned off or did not fire at intended strength. Williams and Wilmore commandeered the capsule manually for about one hour as teams on the ground assessed the issue.

“From that point on, you could tell that the thrust was degraded,” Wilmore said. “But it was still impressive.”

Even with less-than-optimal performance, the thrusters completed what Wilmore described as a perfect maneuver as they navigated the final 10 meters to dock Starliner with the space station.

According to Williams, the astronauts talk with mission crews once per week to share and analyze the data they’ve collected. She highlighted the capsule’s ability to serve as a “safe haven” in the event of an ISS evacuation—a role it fulfilled last month after a Russian satellite broke up in orbit.

“We are having a great time here on the ISS,” said Williams. “I’m not complaining, Butch isn’t complaining, that we’re here for a couple extra weeks.”

One question NASA and Boeing have received is whether Starliner could bring Williams and Wilmore home right now. Officials insist it could, but only in an emergency situation that would require the ISS to be evacuated. The astronauts were asked about their confidence level in that scenario.

“I feel confident that, if we had to—if there was a problem with the International Space Station—we could get in the spacecraft and undock, talk with our team, and figure out the best way to come home,” said Williams.

She later added, “I have a real good feeling in my heart that the spacecraft will bring us home no problem.”

Wilmore said he and his crewmate “trust the tests we are doing are the right ones we need to do to get us the right answers, to give us the data we need to come back,” adding that they are “absolutely ready” for a return based on current engineering data.

NASA could send a SpaceX Crew Dragon capsule—which has completed all eight ISS Commercial Crew rotation missions to date—to retrieve the astronauts should Starliner’s issues persist. On Wednesday, Stich said the space agency has not yet opened those discussions with SpaceX, though he did not rule out the possibility.

The astronauts also described their view of Hurricane Beryl from space, saying that their families—who live in Texas and were in the storm’s path—are doing well. Wilmore said he is “90 percent sure” he could see the storm forming off the West coast of Africa days before it was named.

The 20-minute call concluded with some zero-gravity backflips by Williams and a big, smiling thumbs-up from Wilmore.

NASA, Boeing Share More Info

Stich and Mark Nappi, vice president and general manager of Boeing’s Commercial Crew program, addressed the media following the astronauts’ remarks.

According to Stich, Starliner will need to undock before mid-August, when SpaceX’s Crew-8 team swaps with the incoming Crew-9. Williams and Wilmore will need to return a few days before the Crew-9 launch window opens. Starliner remains a “go” for return in an emergency scenario, officials said. But they prefer to wait until ground testing is complete before attempting a by-the-books return,

Stich estimated that hot fire testing at White Sands could “optimistically” wrap up by the end of July, though it could be extended. Teams are working toward a nominal return flight readiness review, standard for crew rotation missions, that would give the green light to finish the mission as planned. 

Should more time be needed, NASA is in the process of approving a 45-day extension of the CFT, which is contingent on the health of Starliner’s batteries. According to Stich, those systems have shown no sign of wear and tear.

The goal of the test campaign is to recreate the firing pattern of one of Starliner’s faulty thrusters using an identical thruster—designed for a future mission—on the ground. Hot fire testing began on July 3, but Stich said crews have so far been unable to achieve the temperatures experienced by the thruster in orbit. Engineers believe the unusual firing pattern could be due to excess heat.

Teams will then attempt to predict how the thrusters might behave as Starliner undocks and flies home. Based on their learnings, they could modify the spacecraft’s flight path, deactivate certain thrusters, or fire them at different rates. Williams and Wilmore are capable of piloting Starliner manually if issues arise.

At the same time, Stich said White Sands personnel are evaluating the service module for Starliner’s inaugural crew rotation mission, Starliner-1, scheduled for February. The current service module has contended with a series of helium leaks, for which crews are attempting to uncover the root cause. Starliner-1’s service module won’t be redesigned, but Nappi said future models could incorporate changes based on the testing at White Sands.

The Outlook

Extended ISS stays are not necessarily uncommon, and the space station is designed to accommodate crew for months at a time if needed.

NASA astronaut Frank Rubio, for example, set a U.S. spaceflight record when his planned six-month mission was nearly doubled to 371 consecutive days aboard the orbital laboratory. Unlike Starliner, the Russian Soyuz capsule that ferried Rubio to the ISS was quickly ruled out as an emergency return vehicle, lending credence to the idea that Boeing’s issues are less severe.

However, NASA and Boeing face the added pressure of certification after close to a decade of delays to the Starliner program. In a prior press conference, Stich acknowledged that NASA and Boeing “understand it’s going to take a little bit longer” to certify Starliner than originally planned.

On Wednesday, the Commercial Crew manager said teams will decide between Starliner-1 or SpaceX Dragon’s Crew-10—which are booked for the same February launch window—once the CFT ends and postflight analysis is complete. The longer that takes, he said, the more likely it is that SpaceX will take over the mission.

Nappi agreed with that assessment, citing the need to understand and fix Starliner’s helium leaks as the biggest obstacle to certification.

NASA and Boeing said Wilmore and Williams will make one more Earth-to-orbit call before they depart the ISS, with more details to come.

During a media briefing on Friday, NASA and Boeing representatives said the astronauts’ return to Earth will come after ground testing at the White Sands Test Facility in New Mexico is complete. Teams are working to re-create some of the issues experienced by the reusable spacecraft during its inaugural crewed flight to the orbital laboratory.

According to Steve Stich, manager of NASA’s Commercial Crew program, Starliner was originally deemed safe for a stay as long as 45 days on the ISS. Crews are in the process of extending its battery life, which Stich said will keep the risk level manageable for another 45 days, at least.

However, he conceded that NASA and Boeing “understand it’s going to take a little bit longer” to certify Starliner than previously planned. The spacecraft is scheduled to fly its first service mission, Starliner-1, early next year. Officials said SpaceX’s Crew Dragon, which has completed all eight commercial crew rotation missions to the ISS to date, could take that slot.

“We’re not in any rush to come home,” Stich said Friday. “The risk for the next 45 days is essentially the same as for the first 45 days.”

Added Ken Bowersox, associate administrator of NASA’s Space Operations Mission Directorate: “We have the luxury of time.”

Stich, Bowersox, and Mark Nappi, the manager of Boeing’s commercial crew program,  reiterated that “engineering data suggests” Starliner is safe to return Wilmore and Williams to Earth in the event of an emergency.

Officials also reported that the spacecraft is in “good shape” despite two lingering issues—a set of helium leaks and faulty thrusters.

A total of five helium leaks have sprung up on Starliner’s service module, which makes tiny maneuvers to the spacecraft to assist in docking and keep it in orbit. After testing the helium manifolds earlier this month, NASA found that leak rates had declined. Stich on Friday said those rates have not changed.

The other issue involves the service module’s thrusters, some of which did not fire at full strength en route to the ISS. These were also assessed earlier this month, and Stich said performance on all thrusters is between 80 and 100 percent.

It appears the thrusters are the main factor necessitating a longer mission for Starliner. As soon as Tuesday, engineers will begin testing an identical component at White Sands to re-create the firing pattern of one of the in-orbit thrusters. Officials said the campaign is expected to last several weeks and could be extended.

According to Nappi, teams want to keep Starliner in space for the evaluations because they could inform additional in-orbit tests or a modification of the spacecraft’s undocking procedure. He said crews do not yet understand the issue well enough to fix them permanently and that it would be “irresponsible” not to use additional time to conduct testing. Starliner’s crew module is reusable for up to 10 missions, but the service module will be jettisoned during the CFT.

Nappi said he has been in contact with Wilmore and Williams and that they remain in good spirits, describing Starliner as “pristine and precise.” The astronauts are able to communicate with their families daily and according to officials are not “stranded.”

On Wednesday, Starliner got another real-life test when an in-orbit satellite breakup created a debris field that hurtled toward the ISS. Wilmore and Williams tested the spacecraft’s ability to act as a “safe haven” in the case of a contingency on the space station, getting inside, powering it up, and sealing the hatch. They remained inside for an hour and according to officials were prepared to initiate an undocking if necessary.

The space agency on Thursday announced it awarded SpaceX a contract, worth up to $843 million, to build a vehicle that will deorbit the space station when it is retired in 2030. At the end of the laboratory’s lifespan, NASA will use the SpaceX-built vehicle to bring it crashing down into a remote section of the Pacific Ocean.

The Biden administration in 2021 committed to extend ISS operations through the end of the decade. After that, it is planned to be replaced by an array of NASA-funded commercial space stations.

“Selecting a U.S. Deorbit Vehicle for the International Space Station will help NASA and its international partners ensure a safe and responsible transition in low Earth orbit at the end of station operations,” said Ken Bowersox, associate administrator of NASA’s Space Operations Mission Directorate. “This decision also supports NASA’s plans for future commercial destinations and allows for the continued use of space near Earth.”

Once the vehicle is developed, NASA will take over and oversee its operation. Like the ISS, it is expected to break up as it throttles toward the Earth. A launch service will be procured in the future—the agency currently uses SpaceX’s Falcon rocket to launch Commercial Crew rotation missions to the orbital laboratory.

Deorbiting the ISS will be the responsibility of the U.S., Canada, Japan, Russia, and member countries of the European Space Agency (ESA). Since 1998, the ESA, NASA, Canadian Space Agency (CSA), Japan Aerospace Exploration Agency (JAXA), and Russia’s Roscosmos have operated the space station, occupying it continuously for almost a quarter of a century.

In that time, it has been used to conduct microgravity experiments, test technologies that could be used to explore the moon and Mars, and, more recently, host commercial activities such as private astronaut missions.

According to an FAQ on NASA’s website, the agency expects itself to eventually become one of several customers, rather than a provider, of those services in a commercial space marketplace. As private companies take over low-Earth orbit operations, it will focus on flying humans to the moon, Mars, and beyond.

The first crewed lunar landing in the Artemis moon program, for example, is scheduled for September 2026. SpaceX is involved in that effort, too, developing the landing system that will put astronauts on the moon’s south pole.

NASA weighed several options for decommissioning the ISS, including a disassembly in space or boost to higher orbit, before settling on a controlled reentry. It will lower the station’s altitude using onboard propulsion before deploying SpaceX’s specially designed deorbit vehicle to bring it back into the atmosphere.

After lining up the debris footprint over an uninhabited area of the ocean, the space agency will give the all clear for one final burn. Most of the laboratory is expected to melt, burn up, or vaporize.

NASA in 2021 selected three private companies—Blue Origin, Northrop Grumman, and Starlab Space, a joint venture between Voyager Space and Airbus—to develop free-flying commercial alternatives to the space station. The firms were awarded space act agreements totaling $415 million.

Another private partner, Axiom Space, is designing four modules that will attach to the ISS and later jettison to form another commercial space lab. The company is in the design review phase and is on schedule to launch its first module in 2026 under a contract worth up to $140 million.

All four spacecraft are expected to be operational before the end of the decade to ensure a smooth transition away from ISS operations, but NASA will first need to certify them.

The post NASA Picks SpaceX to Deorbit the ISS appeared first on FLYING Magazine.

The mission, which has faced a series of setbacks since an initial launch attempt was scrubbed on May 6, is now targeted for 10:52 a.m. EDT on Wednesday, with a backup launch window available Thursday.

The Starliner CFT is intended to be the spacecraft’s final test flight before NASA moves to certify it for service missions to the ISS, the first of which could take place next year. To date, all eight Commercial Crew rotation missions to the orbital laboratory have been flown by SpaceX’s Crew Dragon. 

The company signed its own multibillion-dollar contract with the space agency at the same time as Boeing but has already cemented itself as an invaluable partner. The same cannot be said for the aerospace giant, which has flown Starliner to the ISS just once.

CFT launch attempts have been delayed or scrubbed due to a litany of issues. First, it was a faulty pressure regulation valve on United Launch Alliance’s (ULA) Atlas V launch vehicle, which will carry Starliner into orbit. Then, crews discovered a small helium leak on Starliner itself, involving one of the 28 reaction control system thrusters on its service module. These small engines use helium to make minor maneuvers and keep Starliner in orbit.

NASA and Boeing have since described the leak as stable but have opted not to repair it, which would require Starliner to be unstacked from Atlas V and could take months. However, in investigating the root cause of the leak, crews discovered what the space agency described as a “design vulnerability” in the capsule’s propulsion system.

In a scenario NASA estimates has a likelihood of about 0.77 percent, the original leak could combine with an adjacent leak to prevent Starliner from performing a deorbit burn. That’s the maneuver that returns a spacecraft to Earth’s atmosphere following its mission.

All of this work identifying and assessing risk pushed the CFT back to Saturday. But yet another problem forced a cancellation of the launch just a few minutes before takeoff—and made a second go-around on Sunday infeasible.

According to the Starliner team, the issue is again on ULA’s side of things.

During the countdown, ground support equipment on the pad at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida experienced issues, which crews traced to a power supply unit on one of three chassis on Atlas V’s Centaur upper stage. The power supply unit indirectly powers Centaur’s topping valves during the launch sequence, and all three chassis must be running in order for the countdown to be completed.

According to Tory Bruno, CEO of ULA, the chassis with the faulty power unit was quickly replaced. The new equipment has been retested and was functioning normally as of Sunday. NASA and Boeing added that they did not observe any physical damage to Starliner or Atlas V, and crews will perform a “full failure analysis” to determine what went wrong.

NASA astronauts Butch Wilmore and Suni Williams, Starliner’s first human passengers, remain in quarantine at Kennedy Space Center. If all goes according to plan, Wilmore and Williams will dock with the ISS later this week. There, they will spend about one week performing tests of Starliner’s systems as NASA prepares for the program’s next step: certification.

After that, Starliner would begin alternating six-month Commercial Crew rotation missions with SpaceX’s Dragon.

The post New Starliner Launch Target Identified After Setback appeared first on FLYING Magazine.

After postponing the previously announced May 25 launch attempt of the Starliner CFT on Tuesday, NASA on Wednesday said that it, Boeing, and launch provider United Launch Alliance, a joint venture between Boeing and Lockheed Martin, are targeting no earlier than Saturday, June 1, at 12:25 p.m. EDT for the next attempt. Additional launch windows include Sunday, June 2, Wednesday, June 5, and Thursday, June 6.

The postponement is the latest in a string of delays that have impacted the mission—and plagued the Starliner program more broadly—for years. An initial launch attempt was scrubbed hours before takeoff on May 6.

The setback follows the discovery of what NASA and Boeing described as a small helium leak on Starliner’s service module, which is designed to power and maneuver the autonomous spacecraft on its journey to the ISS.

According to NASA, Starliner teams have been meeting extensively to identify a new launch date, but further work remains. The agency said the current leak remains stable but that crews are now conducting follow-on performance and propulsion system assessments “to understand potential helium system impacts on some Starliner return scenarios.”

NASA will also perform a Flight Test Readiness Review to recap the work that has been done since May 6 and explain the rationale for attempting the next launch. A date for that review has not been identified but will be announced once selected, it said.

“It has been important that we take our time to understand all the complexities of each issue, including the redundant capabilities of the Starliner propulsion system and any implications to our Interim Human Rating Certification,” said Steve Stich, manager of NASA’s Commercial Crew program. “We will launch [astronauts] Butch [Wilmore] and Suni [Williams] on this test mission after the entire community has reviewed the teams’ progress and flight rationale at the upcoming Delta Agency Flight Test Readiness Review.”

NASA views Starliner as an alternative to SpaceX’s Crew Dragon for missions to low-Earth orbit. Dragon has flown each of the space agency’s eight Commercial Crew rotation missions, ferrying astronauts to and from the ISS, and will facilitate the upcoming Crew-9 mission scheduled for August.

But NASA wants to keep two reusable spacecraft in its fleet in case of a contingency, such as the incident that stranded astronaut Frank Rubio on the orbital laboratory for six months.

Boeing and SpaceX in 2014 each signed multibillion-dollar contracts with the agency to secure test flights and several Commercial Crew missions for their respective vessels. SpaceX has since expanded its arrangement multiple times, while Starliner—which is under contract for six flights—has languished in the development phase.

The Starliner CFT is intended to be the spacecraft’s final test flight before NASA certifies it for Commercial Crew rotation flights. If all goes according to plan, the spacecraft’s first commercial mission to the ISS, Starliner-1, could take place next year. But the delays continue to pile up.

The mission was initially scrubbed due to an oscillating pressure regulation valve on ULA’s Atlas V rocket, which will send Starliner into orbit. The partners set a new target launch date of May 10, later revising it to May 17 to give crews additional time to resolve the issue.

Then, last week, teams discovered a new problem—this time involving a helium leak on one of the Starliner capsule’s 28 reaction control system thrusters. Helium allows the thrusters to fire and make minor maneuvers in orbit. As a result, the launch was pushed to no earlier than Tuesday, a timeline that was then revised yet again to Saturday.

With Wednesday’s announcement, the partners are now nearly one month behind schedule, placing the Starliner team in a bind. On one hand, the safety of the astronauts must be prioritized. But on the other, there is some pressure to launch sooner rather than later.

As Ars Technica’s Stephen Clark notes, the ISS docking schedule gets a bit crowded after July, so there is some pressure for Starliner teams to launch sooner rather than later. In addition, Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida—from where Starliner will launch—is used by ULA for other Atlas V and Vulcan Centaur launches.

The problem with the relief valve on the upper stage of the Atlas rocket was detected about two hours before the scheduled 10:34 p.m. EDT launch from Cape Canaveral.

“In a situation like this, if we see any data signature is not something that we have seen before, then we are just simply not willing to take any chances with what is our most precious payload,” United Launch Alliance spokesman Dillon Rice told reporters.

ULA is providing the rocket to boost the capsule into orbit for a rendezvous with the International Space Station (ISS).

Astronauts Butch Wilmore and Suni Williams had just strapped in when the decision to scrub was made. It’s not known how long it will take to fix the valve.

It’s the latest in a series of issues encountered getting the Starliner to space, although this is the first issue with the launch system. The first uncrewed test launch of the capsule in 2019 failed to get to the right orbit for the ISS. The second test reached the space station, but after it returned problems were found with the parachutes and flammable tape was discovered in the electrical system.

SpaceX this week quietly added a “Human Spaceflight” tab to its website, listing four destinations to which customers can book flights: Earth orbit, the ISS, lunar orbit, and Mars. It is unclear when the new offerings were added.

Pricing information for the missions does not appear to be available. But the webpage directs customers to an email address, humanspaceflight@spacex.com, where they can inquire to book a flight. Missions will begin later this year, the page says, starting with flights to Earth orbit.

FLYING reached out to that email and SpaceX’s press email but did not receive an immediate response.

SpaceX describes its Earth orbit missions as offering a view of the planet from 300 kilometers up. The missions, seating two to four passengers, will last three to six days, offering 360-degree views.

According to the webpage, seats and “on-orbit research opportunities” will be available in late 2024. Regarding the latter offering, SpaceX says it is seeking “exceptional science and research ideas” to study ways to make life in space and on other planets a possibility.

The in-orbit research missions would be facilitated by the company’s Dragon capsule, which since 2012 has ferried more than 1,000 research experiments to low-Earth orbit and the ISS. Customers can submit a research proposal, which SpaceX will either accept or decline. If accepted, the applicant will put together a detailed plan, working with the company to finalize a mission profile, train crews, certify hardware, and collect data.

Two human spaceflight research opportunities are listed on SpaceX’s website: fitness-focused and exploration-focused research. The latter centers largely on the development of medical capabilities for long-duration missions—perhaps to Mars, for example. Mental and physical health and virtual or augmented reality are listed as areas of research interest.

“All Dragon and Starship missions have the ability to conduct scientific research to improve life back on Earth as well as raise awareness to a global audience,” the page reads.

Ten-day commercial missions to the ISS, according to SpaceX, will be available as early as 2025. These would transport up to four people or 192 kilograms of cargo to the orbital laboratory, where passengers could conduct research or simply pay a visit.

Missions to lunar orbit and Mars do not have listed timelines. But the webpage advertises seven-day trips around the moon with up to 12 passengers, with private quarters included. A mission profile for flights to Mars simply lists the Red Planet’s day length, force of gravity, and average distance from Earth.

For all missions, passengers will don a 3D-printed helmet “with customized padding [that] houses microphones for communication and valves that regulate the suit’s pressure systems,” per SpaceX’s description.

The vehicles listed under the Human Spaceflight tab are the Dragon capsule, which is already in use by NASA, and Starship, the reusable upper stage of the company’s massive spacecraft.

Starship and SpaceX’s Super Heavy launcher combined form the largest and most powerful rocket ever constructed, standing close to 400 feet tall when stacked. However, the gargantuan vehicle has been grounded after each of its three uncrewed orbital test flights.

Interestingly, the addition of human spaceflight offerings to SpaceX’s website suggests that the company expects to build on Starship’s most recent flight, and quickly—fast enough to offer missions to lunar orbit in the not-so-distant future. The jumbo rocket is also a key component of NASA’s Artemis II and Artemis III missions to the moon’s orbit and surface, respectively.

SpaceX is not the only company to offer cosmic tourism for paying customers, nor will it be the first to actually deliver on that offering.

Blue Origin in 2021 was the first to fly humans beyond the atmosphere, ferrying CEO Jeff Bezos and Star Trek icon William Shatner to the edge of space. Virgin Galactic followed in June 2023 with its inaugural commercial launch and is now offering monthly suborbital flights for a few hundred thousand dollars per ticket.

Musk and SpaceX’s ambitions, however, are grander than those of their rivals, culminating in the establishment of human colonies on the moon and other planets. But first the company will need to prove it can safely fly humans around the Earth.

NASA’s SpaceX Crew-6 mission, which concluded in September, sent NASA astronauts Stephen Bowen and Woody Hoburg and United Arab Emirates astronaut Sultan AlNeyadi on a 186-day trip to the International Space Station, where they rendezvoused with NASA astronaut Frank Rubio. But it was anything but a vacation.

“I used to joke about the fact that a lot of times in our videos, when we show what’s going on, we spend about a third of our time showing the fun stuff,” Bowen told FLYING at a media event at NASA Headquarters alongside his three crewmembers. “Work is way more than a third of the time we spend up there.”

The mission included several firsts. Rubio, for example, set the U.S. record for most consecutive days in space by the end of his 355-day stay, which was extended six months after the capsule that brought him to the space station was damaged. AlNeyadi became the first Arab to complete a spacewalk.

But the astronauts also conducted more than 200 experiments during their stay at the orbital lab—many of which could address pressing needs on Earth and far, far beyond.

To the Space Station and Back

Crew-6 began with the launch of a SpaceX Dragon Endeavor capsule, strapped to a Falcon 9 rocket, from Kennedy Space Center in Florida. Bowen, Hoburg, AlNeyadi, and Russian cosmonaut Andrey Fedyaev were its occupants. Rubio had launched previously aboard a Soyuz MS-22.

Bowen, a veteran of multiple trips to the space station, was right at home. But for Rubio, Hoburg, and AlNeyadi, Crew-6 was their first time in space.

“Learning to fly for the first couple days is pretty difficult,” Rubio said.

For AlNeyadi, adjusting to the lack of spatial awareness was the biggest challenge

“Everything is very quick aboard the space station…We have 16 sunrises and 16 sunsets every day,” AlNeyadi told FLYING.

Bowen said the orbital lab has come a long way since his first visit in 2008. He was part of several assembly missions, which doubled the space station’s occupancy from three to six, installed technology such as a water recycling system, and delivered research and stowage modules. Crews also replaced the laboratory’s batteries several times.

“We were part of that first step of really making the space station functional,” Bowen told FLYING. “We did a lot of things with just three people on board. But as soon as we got up to six people, the ability to do the actual science—the business of the space station—exploded.”

The astronauts spent the next six months growing plants, researching tissue chips for heart, brain, and cartilage tissue, and conducting hundreds of other experiments for ISS Expedition 69. NASA expeditions refer to the crew occupying the space station—Rubio, Bowen, Hoburg, and AlNeyadi were the 69th such team.

After finishing their work, the astronauts began reentry, splashing down on September 4 after 186 days.

“Becoming a plasma meteorite when you’re coming home is pretty exciting stuff,” said Rubio.

But the research and experiments the crew performed are expected to have an impact long after the mission’s conclusion.

Charting the Future

Despite Rubio’s excitement, launch and reentry may have been the dullest segment of the mission—the crew had more than 200 experiments to fill their time.

“The work is continuous; the work is ongoing,” said Bowen. “Maintaining the space station, like you maintain your house, takes a big chunk of your time. The amount of science we can do now is incredible. Every day we were up there, there’s four of us in the [U.S. Orbital Segment] working.”

Just days after the astronauts’ arrival, they received a cargo vehicle full of materials for experiments. Crewmembers worked throughout the day, sometimes together and sometimes individually, coming together at dinnertime to debrief.

“We are testing hundreds of technologies, and many of them are becoming spinoffs for humanity when utilized here on Earth,” AlNeyadi told FLYING.

For example, astronauts studied how they could grow plants such as tomatoes in harsh and unforgiving environments, either on Earth or in space. They also applied experimental medications to heart cells and printed biological material such as knee cartilage, using technology that could one day print organs for patients on the blue planet.

The crew even ran competitions with university students. Competing teams were able to program a flying robot and control its flight on the space station from Earth.

Perhaps the most consequential research involved a water recycling system, which allowed the astronauts to drink their own urine for the majority of their stay (move over, Bear Grylls). The system may sound outlandish, but it could hold real benefits for humanity.

“Imagine taking the same technology and providing it to people in need in remote areas where they lack water,” said AlNeyadi.

The experiments will also play a key role in NASA’s Artemis program: a series of missions intended to return Americans to the moon for the first time in half a century. According to the crew, learning to live and work in space will be essential for those journeys. Artemis II will send astronauts into lunar orbit in 2025, while Artemis III will attempt to land them on the moon’s surface the following year.

“Knowing that you’re affecting the future of humanity and inspiring future generations, that’s super important to us,” said Rubio.

As important as their work was, the astronauts would not have been able to complete it without finding ways to blow off a little steam.

One method was to simply go outside. Each crew member got the opportunity to complete a spacewalk, including AlNeyadi, who became the first Arab to accomplish the feat.

“Getting in the suit, going outside, and doing important repairs on the station while seeing those views of Earth was just very special,” said Hoburg.

The crew had to get creative at times—Bowen baked pies for Pi Day, and Rubio cut the other astronauts’ hair. But they found plenty of ways to exercise and have fun—and by the end of the mission, they had become a family.

“What a great group of people I had to hang out with for six months,” said Bowen. “It was just incredible.”

A Collective Effort

Crew-6 included the first astronaut of Salvadoran heritage to reach space (Rubio) and the first Arab to complete an extravehicular activity (AlNeyadi). Those feats are symptoms of a broader trend: the globalization of space exploration.

At one point during Expedition 69, there were 11 astronauts aboard the orbital laboratory, which is designed for a maximum of seven. Occupants hailed from the U.S., UAE, Russia, Denmark, and Japan.

“It’s a very intense period when you’re handing over to a new crew, because you’re basically teaching them a whole new lifestyle in a few weeks,” said Rubio.

But the transition was also a welcome development, according to Bowen.

“We actually get a chance to meet a lot of our colleagues around the world before we ever fly,” he said. “So having that crew come on board, I knew every one of them. It was a lot of fun. It’s just great to have new people on board—and it’s another sign you’re going home too.”

AlNeyadi said the UAE already has benefited greatly from its activities in the final frontier. The country’s space agency has only been around for two decades. But in that short time, it has sent a satellite, Martian probe, and the nation’s first astronaut, Hazza Al Mansouri, into space.

“That was an eye opener for everybody. After that, everybody—every young student in the school—wanted to be an astronaut,” said AlNeyadi, who was appointed UAE minister of youth this month.

The Emirati’s own trip has had an impact too. For example, he said it helped catalyze the UAE’s participation in NASA’s Lunar Gateway project, which aims to build a space station orbiting the moon. The country is the fifth to join the partnership.

NASA is also increasingly relying on private industry to help fill certain gaps for Artemis, a contrast to the government-heavy Apollo program. Rubio said he helped certify all SpaceX launch and recovery assets before his mission, a reflection of the agency’s tight relationship with it, Blue Origin, and other commercial partners.

The hope is that greater collaboration can kick off a groundbreaking new era for space travel, one in which humans are continuously occupying the final frontier.

Bowen shared a story about a pair of glasses he found floating aboard the space station, which he mistook for his own. They weren’t Rubio’s or Hoburg’s either, and AlNeyadi didn’t wear glasses. As the crew soon realized, they belonged to an astronaut who had stayed at the orbital lab years ago: a relic of humanity’s persistent effort to uncover the mysteries of space.

Crew-7 astronauts—picking up where Crew-6 left off—splashed down earlier this month, a few days after the Crew-8 team arrived. Perhaps they too will discover the remnants of explorations past. Undoubtedly, they will build on the foundations of previous missions and push humanity forward.

The Crew-7 mission launched August 26 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. On board were astronauts from four different countries and three continents: NASA’s Jasmin Moghbeli, European Space Agency’s Andreas Mogensen, Japan Aerospace Exploration Agency’s Satoshi Furukawa, and Roscosmos’ Konstantin Borisov.

“After more than six months aboard the International Space Station, NASA’s SpaceX Crew-7 has safely returned home,” NASA Administrator Bill Nelson said in a statement. “This international crew showed that space unites us all. It’s clear that we can do more—we can learn more—when we work together. The science experiments conducted during their time in space will help prepare for NASA’s bold missions at the moon, Mars, and beyond, all while benefiting humanity here on Earth.”

Following its liftoff, the crew traveled 84,434,094 miles during the mission, spent 197 days aboard the space station, and completed 3,184 orbits of Earth, according to NASA.

Crew-7’s return marks the latest milestone for NASA’s commercial crew program and comes a week after the successful SpaceX launch of three NASA astronauts and a Roscosmos cosmonaut to ISS as a crew rotation.
