SpaceX’s Dragon spacecraft – carrying several thousand pounds of critical science, hardware, and crew supplies – is on its way to the International Space Station following a successful launch from NASA’s Kennedy Space Center in Florida. The company’s Falcon 9 rocket lifted off from Launch Complex 39A at 8:30 p.m. EDT, beginning SpaceX’s 27th resupply services mission to the orbiting laboratory.
Dragon is now safely in orbit. A series of thruster firings will help Dragon reach the space station about 36 hours later. Upon its arrival, it will autonomously dock to the station’s Harmony module, with NASA astronaut Woody Hoburg monitoring operations. Live coverage of Dragon’s arrival will air on NASA TV, the NASA app, and the agency’s website beginning at 6:15 a.m. Thursday, March 16. Docking is scheduled for approximately 7:52 a.m.
In addition to delivering station supplies, fresh food, and hardware, Dragon also will deliver multiple science and research investigations, including the final two experiments of the National Institutes for Health and International Space Station National Laboratory’s Tissue Chips in Space initiative. Both experiments – the Cardinal Heart 2.0 and Engineered Heart Tissues-2 – use small devices containing living cells that mimic functions of heart tissues and organs to understand the role of microgravity on human health and use this information to improve health on Earth.
Dragon will spend about a month attached to the space station before autonomously undocking and returning to Earth with research and return cargo, splashing down in the off the coast of Florida.

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.
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.
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:

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.
