Born in Killeen, Texas, and raised in Atlanta, Kimbrough was selected as an astronaut in 2004. This will be Kimbrough’s third trip to space and his second long-duration stay at the space station. The increase of the full space station crew complement to seven members – over the previous six – will allow NASA to effectively double the amount of science that can be conducted in space. The Crew-2 astronauts will remain aboard the space station for approximately six months as expedition crew members, along with three crewmates who will launch via a Russian Soyuz spacecraft. 2, and the launch of NASA’s SpaceX Crew-1 mission, which is targeted for late September. JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide and ESA (European Space Agency) astronaut Thomas Pesquet will join as mission specialists.Ĭrew-2 is targeted to launch in spring 2021, following the successful completion of both NASA’s SpaceX Demo-2 test flight mission, which is expected to return to Earth Aug. NASA astronauts Shane Kimbrough and Megan McArthur will serve as spacecraft commander and pilot, respectively, for the mission. NASA and its international partners have assigned crew members for Crew-2, which will be the second operational SpaceX Crew Dragon flight to the International Space Station as part of NASA’s Commercial Crew Program. As an active duty Army astronaut, Kimbrough, a member of STS 126 (Space Shuttle Endeavour), flew aboard a Soyuz spacecraft to the International Space Station for NASA Expeditions 49 and 50. Army (Ret.) and NASA astronaut Shane Kimbrough. Although no matter which career path he takes, Rubinfien pledges to continue to contribute to American space exploration in meaningful ways.Official Portrait of U.S. He dreams of flying in space and eventually setting foot on Mars. The opportunity to conduct research in space has significantly affected Rubinfien’s career aspirations. Astronaut Jack Fisher, who carried out Rubinfien’s experiment onboard the ISS, congratulated Rubinfien from orbit and thanked him for contributing to the incredible science being done on the space station to benefit humanity. Rubinfien was the 2016 winner of the Genes in Space competition, and his experiment launched to the ISS on Orbital ATK CRS-7 in April. “Telomeres are of interest to NASA for their connections to cellular aging and senescence-related diseases that astronauts may develop during spaceflight.” “Unlike previous assays, this one should be capable of assessing changes in telomere length completely in orbit, without having to send materials back and forth from Earth,” Rubinfien said. Rubinfien’s experiment aims to successfully amplify telomeric DNA in space, a necessary step in creating an assay capable of measuring changes in telomere length during spaceflight. Understanding how spaceflight affects telomere length helps scientists elucidate causes of disease on Earth, but it is also important for the safety of astronauts on long-duration spaceflight missions to the Moon, Mars, and beyond. This abnormal regulation has been implicated in a variety of diseases including cardiovascular disease and some cancers. Although it is natural for telomeres to shorten over time as a person ages, stresses such as those experienced during prolonged spaceflight can lead to abnormal regulation of telomere length. Spaceflight induces many changes within the human body, including structural changes to the DNA inside our cells.
