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.

It was a picture-perfect launch during a sun-splashed afternoon on Florida’s Space Coast, as NASA astronauts Nicole Aunapu Mann, and Josh Cassada, along with JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata and Roscosmos cosmonaut Anna Kikina blasted off from Kennedy Space Center on NASA’s SpaceX Crew-5 mission.

“The weather couldn’t have been better here at the Kennedy Space Center,” said Steve Stich, manager of NASA’s Commercial Crew Program at Johnson Space Center in Houston, during a postlaunch news conference at Kennedy about 90 minutes after launch. “We didn’t have to look at any weather on a monitor, we could just look out the window and see a beautiful blue sky.”

SpaceX’s Falcon 9 rocket, with the company’s Dragon spacecraft – named Endurance – atop, lifted off from Kennedy’s Launch Complex 39A at noon EDT. Crew members are now a few hours into their 29-hour trip to the International Space Station for a science expedition mission.

“It was an outstanding launch,” said Joel Montalbano, manager of the International Space Station Program at Johnson. “Just a fantastic day to be in human spaceflight.”

Crew-5 marks the first spaceflight for Mann, Cassada, and Kikina, and the fifth for Wakata. This is the sixth SpaceX flight with NASA astronauts – including the Demo-2 test flight in 2020 to the space station – as part of the agency’s Commercial Crew Program.

Mann has become the first Native American woman in space.

After docking, Crew-5 crewmates will be welcomed inside the station by the seven-member crew of Expedition 68. The astronauts of NASA’s SpaceX Crew-4 mission will undock from the space station and splash down off the coast of Florida later this month.

“These are real human endeavors, and there’s a team here that had to recover from the hurricane (Ian) last week,” said Kathy Lueders, associate administrator, Space Operations Mission Directorate at NASA Headquarters. “The fact that we’re here today is a testimony to all the work that team did.”

Crew-5 is scheduled for a long-duration stay of up to six months aboard the space station before returning to Earth in the spring of 2023. The crew will conduct new scientific studies to prepare for human exploration beyond low-Earth orbit and benefit life on Earth.

Planned experiments include studies on printing human organs in space, understanding fuel systems operating on the Moon, and advancing research in heart disease. These are just some of the more than 200 science experiments and technology demonstrations that will take place during the Crew-5 mission.

Safely in orbit, Endurance remains on schedule for a rendezvous with the orbiting laboratory for tomorrow’s main activities.

“Dragon has completed its initial on-orbit checkouts and soon it will start performing a series of burns that will help it catch up with the International Space Station for docking tomorrow,” said Sarah Walker, director of Dragon Mission Management at SpaceX.

NASA TV and the agency’s website are providing comprehensive coverage of upcoming Crew-5 events. On Thursday, Oct. 6, live mission coverage begins at 3:15 a.m. EDT – continuing through Dragon spacecraft docking at 4:57 p.m. EDT, hatch opening at 6:42 p.m., and the welcome ceremony at the space station at 8:15 p.m.
