The Crew-2 mission is the second of six crewed missions NASA and SpaceX will fly as part of the agency’s Commercial Crew Program. This mission has several firsts, including:

  • First commercial crew mission to fly two international partners;
  • First commercial crew handover between astronauts on the space station as Crew-1 and Crew-2 astronauts will spend about five days together on station before Crew-1 returns to Earth;
  • First reuse of the Crew Dragon spacecraft and Falcon 9 rocket on a crew mission –Crew Dragon Endeavour flew the historic Demo-2 mission and the Falcon 9 flew astronauts on the Crew-1 mission; and,
  • First time two commercial crew spacecraft will be docked to station at the same time.

“When I see a launch I immediately think of what it took to reach this milestone and the dedication of all the people who made it happen,” said Steve Stich, manager of NASA’s Commercial Crew Program. “There’s obviously a long way to go, but now we can celebrate the Crew-2 launch and look forward to seeing them join their other Expedition 65 colleagues as we prepare to bring Crew-1 home next week.”

Kimbrough, McArthur, Hoshide, and Pesquet will join the Expedition 65 crew of Shannon Walker, Michael Hopkins,  Victor Glover, and Mark Vande Hei of NASA, as well as Soichi Noguchi of JAXA and Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov. For a short time, the number of crew on the space station will increase to 11 people until Crew-1 astronauts Walker, Hopkins, Glover, and Noguchi return a few days later.

The is the second commercial crew mission to fly a JAXA astronaut. When Hoshide joins astronaut Noguchi during the commercial crew handover period, it will mark the first time two JAXA astronauts are on station at the same time.

“I am extremely honored to witness the successful launch today. It is my utmost pleasure and also for Japan that Japanese astronauts Soichi Noguchi and Aki Hoshide boarded the operational spacecraft of Crew Dragon twice in a row,” said Hiroshi Sasaki, Vice President for Human Spaceflight and Space Exploration. “I believe this is brought by the many years of close cooperation cultivated amongst the international partners, especially between U.S. and Japan through the ISS program. I hope Aki will play an integral role as the second Japanese ISS commander along with his colleague astronauts, creating fruitful outcomes and expanding the human frontier to the Lunar Gateway, the surface of the Moon and even beyond.”

Crew-2 also is the first commercial crew mission to fly an ESA astronaut. Pesquet is the first of three ESA crew members assigned to fly to station on commercial crew spacecraft, kicking off a continuous stay of ESA astronauts on the space station for about a year and a half – in total – for the first time in more than 20 years.

“This is a thrilling time for human spaceflight and this new success of the Commercial Crew Program embodies it – congratulations once again to NASA and SpaceX,” said David Parker, director of human and robotic exploration at ESA. “Starting with astronaut Thomas Pesquet, ESA is delighted to join this new space station chapter, paving the way to the future of exploration side by side with diverse partners. Six months of excellent science and state-of-the-art technology demonstrations now await him, and we know he cannot wait to start working.”

Mission Objectives

The Crew-2 members will conduct science and maintenance during a six-month stay aboard the orbiting laboratory and will return no earlier than October 31. The Crew Dragon spacecraft can stay in orbit for at least 210 days, which is a NASA requirement.

Adding more crew members aboard the microgravity laboratory increases the time available for scientific activities. The November 2020 arrival of the Crew-1 astronauts more than doubled crew hours spent on scientific research and support activities, and Crew-2 will continue the important investigations and technology demonstrations that are preparing for future Artemis missions to the Moon, helping us improve our understanding of Earth’s climate, and improving life on our home planet. An important scientific focus on this expedition is continuing a series of Tissue Chips in Space studies. Tissue chips are small models of human organs containing multiple cell types that behave much the same as they do in the body. Another important element of Crew-2’s mission is augmenting the station’s solar power system by installing the first pair of six new ISS Roll-out Solar Arrays.

Crew Dragon also is delivering almost 250 pounds of cargo, new science hardware, and experiments, including a university student-led investigation to study possible causes for suppressed immune response in microgravity.

During their stay on the orbiting laboratory, Crew-2 astronauts expect to see a range of U.S. commercial spacecraft, including the Northrop Grumman Cygnus; SpaceX cargo Dragon; Boeing CST-100 Starliner, on its uncrewed flight to station; and NASA’s SpaceX Crew-3 Dragon; which is targeted for launch no earlier than Oct. 23. During Crew-2, astronauts also will conduct a variety of spacewalks outside the space station, including the solar array installation.

At the conclusion of the mission, the Crew-2 astronauts will board Crew Dragon, which will then autonomously undock, depart the space station, and re-enter Earth’s atmosphere. Crew Dragon also will return to Earth important and time-sensitive research. NASA and SpaceX are capable of supporting seven splashdown sites located off Florida’s east coast and in the Gulf of Mexico. Upon splashdown, the SpaceX recovery ship will pick up the crew and return to shore.

NASA’s Commercial Crew Program is delivering on its goal of safe, reliable, and cost-effective transportation to and from the International Space Station from the United States through partnership with American private industry. This partnership is changing the arc of human spaceflight history by opening access to low-Earth orbit and the International Space Station to more people, more science, and more commercial opportunities.

The space station remains the springboard to NASA’s next great leap in space exploration, including future missions to the Moon and, eventually, to Mars. For more than 20 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. As a global endeavor, 243 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 3,000 research and educational investigations from researchers in 108 countries and areas.

    Please take care to redirect the definition of a cell, as in a nuclear anatomy does not exist but that the encompassing electrostatic energy which surrounds our existence is that upon which we depend. Si to focus upon the very narrow marrow of that transaction of our senses becomes more secure with that which is seen and that which is not. Thanks again for your endeavors and perseverance. Let it never cease to persist.
