NASA and its industry partners Boeing and SpaceX are planning for the next set of missions to the International Space Station for the agency’s Commercial Crew Program.

Crew-8

NASA’s SpaceX Crew-8 mission to the orbiting laboratory is targeted to launch no earlier than mid-February. The mission will carry NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and mission specialist Jeanette Epps, as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin to the space station to conduct a wide range of operational and research activities. Routine maintenance and processing of the Crew-8 SpaceX Falcon 9 rocket and Dragon spacecraft is in work. This will be the first spaceflight for Dominick, Epps, and Grebenkin, and the third for Barratt. Crew-8 is expected to return to Earth in late August 2024, following a short handover with the agency’s Crew-9 mission.

Starliner Crew Flight Test (CFT)

The first crewed flight of the Starliner spacecraft, named NASA’s Boeing Crew Flight Test (CFT), is planned for no earlier than mid-April. CFT will send NASA astronauts and test pilots Butch Wilmore and Suni Williams on a demonstration flight to prove the end-to-end capabilities of the Starliner system. Starliner will launch atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida, spend approximately eight days docked to the space station, and return to Earth with a parachute and airbag-assisted ground landing in the desert of the western United States.

NASA will provide an updated status of CFT readiness as more information becomes available.

Crew-9

Looking further ahead in 2024, NASA and SpaceX are targeting no earlier than mid-August for the launch of the agency’s Crew-9, SpaceX’s ninth crew rotation mission to the space station for NASA. An crew of four will be announced at a later date.

10th Crew Rotation Mission

The 10th commercial crew rotation opportunity to the space station is targeted for early 2025. NASA is planning for either SpaceX’s Crew-10 or Boeing’s Starliner-1 mission in this slot. The Starliner-1 date was adjusted to allow for the post-flight review of the Crew Flight Test and incorporation of anticipated learning, approvals of final certification products, and completion of readiness and certification reviews ahead of that mission.

The target launch date for NASA’s SpaceX Crew-7 mission to the International Space Station now is 3:49 a.m. EDT Friday, Aug. 25. Additional time was required for teams to complete pad readiness after SpaceX’s recent Falcon Heavy mission lifted off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The adjustment also takes advantage of consecutive launch opportunities and deconflicts the station’s cargo spacecraft traffic schedule.

NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov will launch on a SpaceX Falcon 9 rocket aboard the company’s Dragon spacecraft.

Crew-7 is scheduled to dock to the orbiting laboratory about 2:45 a.m. Saturday, Aug. 26, to the space-facing port of the station’s Harmony module. If needed, Crew-7 has additional launch opportunities on Saturday, Aug. 26 and Sunday, Aug. 27.

NASA’s SpaceX Crew-4 astronauts aboard the Dragon spacecraft safely splashed down Friday off the coast of Jacksonville, Florida, completing the agency’s fourth commercial crew mission to the International Space Station. The international crew of four spent 170 days in orbit.

NASA astronauts Bob Hines, Kjell Lindgren, and Jessica Watkins and ESA (European Space Agency) astronaut Samantha Cristoforetti returned to Earth in a parachute-assisted splashdown at 4:55 p.m. EDT. Teams aboard SpaceX recovery vessels retrieved the spacecraft and astronauts. After returning to shore, all astronauts will fly to NASA’s Johnson Space Center in Houston. Cristoforetti then will board a plane to Europe.

“Welcome home Crew-4! This international crew has spent nearly six months on the International Space Station conducting science for the benefit of all. Their work aboard the orbiting laboratory will help prepare future explorers for future space missions,” said NASA Administrator Bill Nelson. “Working and living on the space station is the opportunity of a lifetime, but it also requires these explorers to make sacrifices, especially time away from loved ones. Kjell, Bob, Jessica and Samantha, thank you for your contributions over the past six months to science, innovation, and discovery!”

The Crew-4 mission launched at 3:52 a.m. EDT April 27 on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. Less than 16 hours later, Dragon docked to the Harmony module’s space-facing port. The astronauts undocked from the same port at 12:05 p.m. Friday, to begin the trip home.

Hines, Lindgren, Watkins, and Cristoforetti traveled 72,168,935 miles during their mission, spent 170 days aboard the space station, and completed 2,720 orbits around Earth. Lindgren has logged 311 days in space over his two flights, and with the completion of their flight today, Cristoforetti has logged 369 days in space on her two flights, making her second on the all-time list for most days in space by a woman. The Crew-4 mission was the first spaceflight for Hines and Watkins.

Throughout their mission, the Crew-4 astronauts contributed to a host of science and maintenance activities and technology demonstrations. Cristoforetti completed two spacewalks with Roscosmos cosmonaut Oleg Artemyev to perform station maintenance and upgrades.

Crew-4 continued work on investigations documenting how improvements to the space diet affect immune function and the gut microbiome, determining the effect of fuel temperature on the flammability of a material, exploring possible adverse effects on astronaut hearing from equipment noise and microgravity, and studying whether additives increase or decrease the stability of emulsions. The astronauts also investigated microgravity-induced changes in the human immune system similar to aging, tested a novel water-reclamation membrane, and examined a concrete alternative made with a material found in lunar and Martian dust.

The spacecraft, named Freedom by Crew-4, will return to Florida for inspection and processing at SpaceX’s Dragon Lair, where teams will examine the spacecraft’s data and performance throughout the flight.

The Crew-4 flight is part of NASA’s Commercial Crew Program and its return to Earth follows on the heels of NASA’s SpaceX Crew-5 launch, which docked to the station Oct. 6, beginning another science expedition.

The goal of NASA’s Commercial Crew Program is safe, reliable, and cost-effective transportation to and from the International Space Station. This already has provided additional research time and has increased the opportunity for discovery aboard humanity’s microgravity testbed for exploration, including helping NASA prepare for human exploration of the Moon and Mars.

NASA and SpaceX now are targeting no earlier than 10:05 a.m. EDT Thursday, Oct. 13, for the agency’s Crew-4 undocking from the International Space Station to begin the return trip to Earth completing a nearly six-month science mission in orbit. Splashdown is targeted several hours later at 5:43 p.m. Thursday off the coast of Florida.

Mission teams continue to monitor a cold front passing over Florida with the potential to bring high winds and rainy weather near the splashdown zones off the Atlantic and Gulf coasts. Mission teams will continue to monitor splashdown and recovery conditions with another weather review around six hours prior to undocking.

Crew 4’s Dragon undocking depends on a variety of factors, including spacecraft readiness, recovery team readiness, weather, sea states, and other factors. Dragon Freedom remains healthy while currently docked to the space station. Back-up undocking opportunities also are available Friday, Oct. 14.

NASA will provide live coverage of the upcoming return activities for the Crew-4 mission with NASA astronauts Bob Hines, Kjell Lindgren, and Jessica Watkins, as well as ESA (European Space Agency) astronaut Samantha Cristoforetti.

Dragon’s hatch closing, undocking, and splashdown coverage will air live on NASA Television, the NASA app, and the agency’s website. NASA also will host an audio only post-splashdown news teleconference. Follow all live events at:

NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti are on their way to the International Space Station, following the picture-perfect launch of the agency’s SpaceX Crew-4 mission. SpaceX’s Crew Dragon spacecraft, named Freedom by the crew, launched atop the company’s Falcon 9 rocket from Kennedy Space Center’s Launch Complex 39A in Florida at 3:52 a.m. EDT.

“This is our fourth crew rotation flight – it’s kind of hard to believe,” said Steve Stich, manager, Commercial Crew Program, NASA’s Johnson Space Center in Houston. “It seems like Demo-2 was just yesterday, and it’s exciting to be here. We had a really clean countdown today – the Falcon 9 rocket did great; the Dragon vehicle did great. It was great to see the crew get in. You could tell they were excited to start their flight off.”

Upon their arrival at the space station, the Crew-4 astronauts will be greeted by NASA astronauts of the Expedition 67 crew already on board. During their six-month stay aboard the microgravity laboratory, Lindgren, Hines, Watkins, and Cristoforetti will join the Expedition 67 crew in conducting a number of science and research investigations.

The Crew-4 astronauts will conduct new and exciting scientific research in areas such as materials science, health technologies, and plant science to prepare for human exploration beyond low-Earth orbit and benefit life on Earth. Experiments will include studies on the aging of immune systems, organic material concrete alternatives, and cardiorespiratory effects during and after long-duration exposure to microgravity. These are just some of the more than 200 science experiments and technology demonstrations that will take place during their mission.

Launching alongside the crew in the Dragon capsule is an investigation that seeks to restore meaningful vision to people suffering from retinal degenerative diseases like retinitis pigmentosa and macular degeneration. The Protein-Based Artificial Retina Manufacturing experiment tests the manufacturing of artificial retinas or retinal implants in microgravity, where it is expected their production could be optimized.

Also traveling to space aboard the Crew Dragon are Smart-Tex shirts as part of the German Space Agency (DLR) investigation called Wireless Compose-2. The shirts are fitted with sensors, wiring, and a communications module to wirelessly transmit data to a base station. The shirt is designed to monitor cardiovascular activity like relative blood pressure and can provide details about heart contraction rate and valve opening and closing times – something normally accessible only through sonography or CT scans. These kinds of wearable technologies could be used to monitor health throughout a long-duration space exploration mission and could lead to a more flexible implementation of this technology in health monitoring equipment on Earth.

Crew-4 is NASA’s fourth crew rotation mission with SpaceX for the agency’s Commercial Crew Program. Lindgren and Cristoforetti have previously traveled to the International Space Station, while it will be the first trip for Hines and Watkins. Crew-4 astronauts are slated to arrive at the space station today, April 27, with docking targeted for 8:15 p.m. EDT. Following docking and hatch opening, a welcoming ceremony is planned for 2:40 a.m. EDT.

Coverage of Crew-4’s arrival to the station will air live on NASA Television and the agency’s website, beginning with docking at 8:15 p.m. EDT.

Earlier on Tuesday, April 26, NASA Administrator Bill Nelson and senior NASA leadership addressed members of the media during a briefing held at the agency’s Kennedy Space Center in Florida for NASA’s SpaceX Crew-4 mission, now less than a day away.

“Flying safely with crew means that you’ve got to do it one step at a time,” said Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters. “So, tomorrow morning, we’re hoping that you’ll get to see a really, really beautiful step, and we’ll get our crew safely to orbit.”

Crew-4 is the fourth crew rotation flight of a U.S. commercial spacecraft under the agency’s Commercial Crew Program. The mission will send NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti to the International Space Station for a rotation science expedition, living and working as part of what is expected to be a 7-member crew.

Lindgren and Hines were assigned to the Crew-4 mission in February 2021 and began working and training on SpaceX’s next-generation human spacecraft and for their stay aboard the space station. Cristoforetti was assigned to the mission in March 2021 and Watkins was added as the fourth crew member in November 2021.

The Crew-4 mission continues NASA’s efforts to restore and maintain American leadership in human spaceflight. Regular commercial crew rotation missions enable NASA to continue the important research and technology investigations taking place aboard the station. Such research benefits people on Earth and lays the groundwork for future exploration beyond low-Earth orbit, starting with the agency’s Artemis missions, which includes landing the first woman and person of color on the lunar surface.

The SpaceX Falcon 9 rocket and Crew Dragon spacecraft, which the crew has named Freedom, are scheduled to lift off at 3:52 a.m. EDT on Wednesday, April 27. Just over 17 hours after launch, the crew is expected to arrive at the orbiting laboratory. Docking is planned for approximately 8:15 p.m. EDT on Wednesday, April 27.

Weather officials with the U.S. Space Force’s 45th Weather Squadron are predicting an 90% chance of favorable weather conditions for launch – this is derived from Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns are cumulus cloud and flight through precipitation rules.

For more than 21 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration to the Moon and Mars. The station’s design requires humans living aboard to maintain it, operate it, and upgrade it; thus, International Space Station operations, including commercial resupply and commercial crew, are essential to the mission.

Live coverage of launch preparations and liftoff will begin at 12 a.m. EDT on Wednesday, April 27, on NASA Television, the NASA app, and the agency’s website.

Six spaceships are parked at the space station including the SpaceX Dragons Endurance and Endeavour; the Northrop Grumman Cygnus space freighter; and Russia’s Soyuz MS-21 crew ship and the Progress 79 and 80 resupply ships.

The integrated NASA, Axiom Space, and SpaceX teams have agreed on a plan for the Axiom Mission 1 (Ax-1) crew to undock from the International Space Station at 8:35 p.m. EDT Saturday, April 23, for a splashdown off the coast of Florida about 1:46 p.m. Sunday, April 24. The decision was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to bring the crew and the SpaceX Dragon Endeavour spacecraft back to Earth safely.

NASA will provide live coverage of departure activities beginning at 6:15 p.m. Saturday, April 23, with hatch closure targeted for 6:30 p.m. Coverage will resume at 8:15 p.m. for the undocking. Teams will continue to monitor weather at the splashdown sites prior to undocking to ensure conditions are acceptable for a safe recovery of the Ax-1 astronauts and Dragon spacecraft.

NASA and Axiom mission planning prepared for the possibility of additional time on station for the private astronauts, and there are sufficient provisions for all 11 crew members aboard the space station. The Ax-1 crew continues to work through previously planned mission activities. The Ax-1 crew and Dragon spacecraft remain healthy.

The departure of Dragon Endeavour from the space station will clear the docking port for the arrival of Dragon Freedom and NASA’s SpaceX Crew-4 astronauts. The earliest potential launch opportunity for the Crew-4 mission is 4:15 a.m. Tuesday, April 26, with additional opportunities Wednesday, April 27, and Thursday, April 28. These launch opportunities are undergoing a more detailed program review to ensure they align with integrated operational timelines. The teams want to provide a two-day gap after Ax-1 return for data reviews from splashdown and to prepare for the Crew-4 launch, including the staging of recovery assets.

The Crew-4 astronauts spent last night at the Kennedy Space Center in Florida rehearsing the countdown to their launch inside the SpaceX Dragon Freedom, the company’s newest crew ship. Overnight, Crew-4 Commander Kjell Lindgren, Pilot Robert Hines with Mission Specialists Jessica Watkins and Samantha Cristoforetti, put on their pressure suits and entered their vehicle conducting a successful dry dress rehearsal. The Falcon 9 rocket, with the Freedom perched atop, stands at Launch Complex 39A.

Expedition 67 crewmates Raja Chari and Tom Marshburn, who are also the SpaceX Crew-3 commander and pilot respectively, spent a little time on Wednesday with their upcoming departure activities. The pair, along with Kayla Barron of NASA and Matthias Maurer of ESA, will wait for the arrival of their Crew-4 replacements before returning to Earth a few days later inside the Dragon Endurance vehicle. The four astronauts had a light-duty day on Wednesday scheduling in some housecleaning tasks.

Over in the Russian segment of the station, cosmonauts Oleg Artemyev and Denis Matveev wrapped up their post-spacewalk activities today stowing their tools and discussing the excursion with specialists on the ground. The duo kicked off a series of spacewalks on April 18 to configure the European robotic arm for operations on the Nauka multipurpose laboratory module. Roscosmos Flight Engineer Sergey Korsakov started his day with electronics and communications maintenance before studying future spacecraft and robotic piloting techniques in the afternoon.
