Michael Reed Barratt is an American physician and a NASA astronaut. Specializing in aerospace medicine, he served as a flight surgeon for NASA before his selection as an astronaut and has played a role in developing NASA's space medicine programs for both the Shuttle-Mir Program and International Space Station. His first spaceflight was a long-duration mission to the International Space Station, as a flight engineer in the Expedition 19 and 20 crew.

STS-134 was the penultimate mission of NASA's Space Shuttle program and the 25th and last spaceflight of Space ShuttleEndeavour. This flight delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station. Mark Kelly served as the mission commander. STS-134 was expected to be the final Space Shuttle mission if STS-135 did not receive funding from Congress. However, in February 2011, NASA stated that STS-135 would fly "regardless" of the funding situation. STS-135, flown by Atlantis, took advantage of the processing for STS-335, the Launch on Need mission that would have been necessary if the STS-134 crew became stranded in orbit.
NASA Astronaut Group 16 was a group of 44 astronauts announced by NASA on May 1, 1996. The class was nicknamed "The Sardines" for being such a large class, humorously implying that their training sessions would be as tightly packed as sardines in a can. These 44 candidates compose the largest astronaut class to date. NASA selected so many candidates in preparation for the anticipated need for ISS crew members, along with regular shuttle needs. Nine of the 44 astronauts selected were from other countries including 5 from Europe and 2 from Canada and Japan.
NASA Astronaut Group 17, were chosen by NASA in 1998 and announced on June 4 of that year. The group of 32 candidates included eight pilots, 17 mission specialists, and seven international mission specialists who became NASA astronauts. They began training in August 1998.
NASA Astronaut Group 15 was a group of 23 NASA astronauts announced on December 8, 1994. Group members adopted The Flying Escargot as their moniker, in reference to two members of the group being from France. The group featured ten pilots, nine mission specialists, and four international mission specialist trainees from France, Canada and Japan.

The first three members of Expedition 28 arrived on the ISS aboard the Soyuz TMA-21 spacecraft on 4 April 2011, and were joined on 9 June 2011 by the three other crew members, who arrived aboard Soyuz TMA-02M. The expedition saw a number of significant events, including the final Space Shuttle mission, STS-135, which took place in July 2011. Expedition 28 was superseded by Expedition 29 on 16 September 2011.
