Peggy Whitson, America’s most skilled astronaut with 665 days in area and 10 spacewalks over three stays aboard the Worldwide Area Station, is poised to construct on her legacy as one of many consensus “GOATs” — biggest of all time — within the American area program.
With a Ph.D. in biochemistry and two stints as commander of the area station, Whitson, a former chief of NASA’s astronaut corps, final flew in area in 2017 after finishing a 289-day station flight. She by no means anticipated to fly in area once more.
However after retiring from NASA and becoming a member of Houston-based Axiom Area as director of human spaceflight, Whitson, now 63, plans to blast off on her fourth flight Sunday, this time as commander of the SpaceX Crew Dragon “Freedom.”
She’ll be joined by retired businessman, race automobile driver and adventurer John Shoffner, serving as co-pilot, and two Saudi Arabian astronauts: F-16 fighter pilot Ali Alqarni and biomedical researcher Rayyanah Barnawi.
“I needed to have the ability to fly in area once more,” Whitson mentioned in an interview with CBS Information, “however the practical a part of Peggy mentioned, no, you are not going to have the ability to. And so, it is only a thrill and a half to have this chance to fly for Axiom.”
It’s the second “personal astronaut mission,” or PAM, to the Worldwide Area Station chartered by Axiom and sanctioned by NASA, which is attempting to encourage private-sector growth of low-Earth orbit.

Neither SpaceX nor Axiom will say how a lot the flight price or how a lot Shoffner and the Saudi authorities chipped in for Alqarni and Barnawi. However seats are thought to price greater than $50 million every.
In any case, Alqarni and Barnawi would be the second and third Saudis to fly in area after Sultan Salman Al-Saud flew aboard the area shuttle Discovery in 1985. They would be the first Saudis to go to the area station, and Barnawi will grow to be the primary Saudi lady to fly in area.
“Analysis has been my ardour in life,” she mentioned at a pre-launch information convention. “I am very joyful and honored to be right here immediately representing the federal government of Saudi Arabia and the Saudi Area Fee as the primary Saudi lady astronaut going to the Worldwide Area Station.
“This can be a nice alternative for me to characterize the nation, to characterize their goals. … This can be a dream come true for everybody.”
Liftoff atop a SpaceX Falcon 9 rocket is deliberate for five:37 p.m. EST Sunday with a backup launch alternative at 5:14 p.m. Monday. It is going to be the tenth piloted flight of a SpaceX Crew Dragon, the California rocket builder’s third non-government mission and the second chartered by Axiom Area.

However as with many afternoon launches this time of 12 months, the climate could possibly be an element with solely a 60 % likelihood of favorable circumstances Sunday, falling to only 20 % “go” on Monday as a result of anticipated thunderstorms.
The Ax-2 crew solely has two pictures at getting off in Could. If the climate or another concern retains them on the bottom previous Monday, the flight may slip into the late summer-fall timeframe due to different already-planned launches, a number of spacewalks and the primary piloted flight of Boeing’s Starliner capsule in July.
“The schedule is de facto tight with all of the missions launching from totally different components of the world,” mentioned Ken Bowersox, director of area operations at NASA. “And it was an actual problem for the crew to search out this two-day window for the (Ax-2) mission.”
Assuming an on-time launch Sunday, Whitson and Shoffner will monitor an automatic rendezvous with the area station, catching up and shifting in for docking on the Concord module’s space-facing port at 9:24 a.m. Monday. For a day-late launch on Monday, docking could be anticipated round 1:30 a.m. Wednesday.
At any time when they arrive, they will be welcomed aboard the station by Expedition 69 commander Sergey Prokopyev and his two Soyuz MS-23 crewmates, Dmitri Petelin and NASA astronaut Frank Rubio, together with NASA Crew 6 fliers Steve Bowen, Woody Hoburg, UAE astronaut Sultan Alneyadi and cosmonaut Andrey Fedyaev.
Throughout an eight-day keep, Whitson, Shoffner, Alqarni and Barnawi plan to hold out 20 analysis tasks, 14 of them developed by Saudi scientists, that vary from human physiology and cell biology to know-how growth. Equally essential, if no more so: public outreach.
“This can be a large, large occasion in Saudi Arabia,” mentioned Derek Hassmann, Axiom chief of mission integration and operations. “Throughout the time they’re docked to ISS, there’s a complete sequence of media occasions scheduled.
Area X.
“One of many focuses of many of those occasions is interacting with school-aged youngsters in Saudi Arabia. And that was one of many causes, simply the timing of the varsity 12 months, that we’re very concerned with getting this flight accomplished in Could. They’ve a complete sequence of post-flight occasions deliberate as nicely.”
Barnawi mentioned “we’re right here as STEM educators for the children to be (attracted) to math and science, know-how, to know that they’ll do extra.”
Added Alqarni: “We’ll be doing three schooling and consciousness experiments with the children and it is going to be a dwell occasion, which goes to be superb for them. It should be an enormous alternative to check the outcomes that that they had on the bottom with the one we’re going to have aboard the ISS.”
One such pupil experiment: constructing a kite and evaluating how one flies aboard the station within the absence of gravity with how student-built kites fly on Earth.
Throughout the Ax-2 crew’s keep aboard the station, the one off-limits space for the rooky guests is the Quest airlock the place delicate spacewalk {hardware} is housed. They are going to be free to go to the Russian section on the invitation of the cosmonauts and they’re skilled to function primary tools with out supervision.
“For the galley and the potty, each important capabilities, clearly, they have an incredible quantity of coaching,” Hassmann mentioned. “However on orbit, as soon as they attain ISS, the primary time they use every of these items, first time they put together their meals within the galley, earlier than they use the bathroom for the primary time, they’ll get a (briefing) from the ISS crew.”
They usually’ll be capable to present their appreciation. Alqarni mentioned he is bringing Saudi espresso and dates to share with the station crew.

Assuming they launch Sunday as deliberate, Whitson and her crewmates plan to undock from the area station on Could 30 for a fiery plunge again to Earth and splashdown off the coast of Florida.
The Ax-2 flight is the second such personal astronaut mission to the station booked by Axiom, an organization led by Mike Suffredini, NASA’s former area station program supervisor, and different authorities and private-sector area veterans.
Axiom Area is growing a module that might be hooked up to the Worldwide Area Station within the subsequent few years to function a precursor to a stand-alone industrial area station.
Whitson’s Ax-2 mission, just like the Ax-1 flight in 2022 earlier than it, is seen as a essential step towards growing the corporate’s area station, an orbital base that can be utilized by authorities and personal astronauts and researchers alike after the Worldwide Area Station is retired on the finish of the last decade.
“The Ax-2 mission represents the continued progress that NASA and trade are making to construct a sturdy industrial economic system in low Earth orbit,” mentioned Angela Hart, supervisor of NASA’s industrial low-Earth orbit growth program.
“The long run we envision for low-Earth orbit builds on the teachings from ISS together with these personal astronaut missions and will get us nearer to our objective of presidency and personal astronauts working facet by facet on commercially owned and operated area stations sooner or later.”
