#YearInSpace Crew Enters Station Joining Expedition 43

Expedition 43 in the Zvezda service module
Scott Kelly, Mikhail Kornienko and Gennady Padalka joined their Expedition 43 crewmates Terry Virts, Anton Shkaplerov and Samantha Cristoforetti in the Zvezda service module for a crew greeting ceremony.

Kelly and Kornienko will spend about a year on the space station to better understand how the human body reacts and adapts to the harsh environment of space. Data from the one-year mission will be used to determine whether there are ways to further reduce the risks on future long-duration missions to an asteroid and eventually Mars.

The crew will support several hundred experiments in biology, biotechnology, physical science and Earth science — research that impacts life on Earth. Data and samples will be collected throughout the year from a series of studies involving Scott and his twin brother, former NASA astronaut Mark Kelly. The studies will compare data from the genetically-identical Kelly brothers to identify any subtle changes caused by spaceflight.

During the expedition, both a U.S. and a Russian cargo resupply vehicle will arrive at the station, bringing several tons of food, fuel, and supplies as well as a host of new science investigations.

Virts, Shkaplerov and Cristoforetti will return home in May 2015. At that time Padalka will become commander for Expedition 44. Padalka will spend six months aboard the outpost, during which he will become the first four-time station commander and record holder for most cumulative time spent in space. Kelly and Kornienko will return to Earth in March 2016 with Expedition 46 after 342 days in space.

  1. Space research is great. The more we research the more we find out about the universe. I am going to look at their activities on social media. Should be interesting.

  2. When Padalka returns to Earth, how will the “life boat” situation be managed? Will a Soyus be used for cargo, to get an extra man capable vehicle up there?

  3. Roscosmos has it worked out. Next fall before Padalka returns to earth, a Soyus will be arriving with a Russian commander and the English classical music singer as a tourist. There may be another tourist on the trip as well, but I don’t know for sure. The English singer will stay on station for 10 days. This Soyus will then be the life boat when Padalka , the singer, and one other occupant return to earth on the Soyus that was just launched.

  4. My name is Hayley and I am eleven years old and I have just subscribed this website. I am very interested in what you have done

  5. Have a wonderful time in the ISS. Year in Space will give unvaluable information for the missions that will take place in the near future.

    All the best to Expedition 43!
