Barratt was assigned to the Expedition 19 crew in February 2008 and launched to the International Space Station in March 2009 aboard Soyuz TMA-14. His stay aboard the ISS continued until the end of Expedition 20 in October 2009.

During Expedition 20, Barratt performed both an EVA and IVA together with Gennady Padalka. The first EVA, on June 5, 2009, lasted for 4 hours and 54 minutes and prepared the Zvezda service module transfer compartment for the arrival of the Poisk module, installed docking antenna for the module, photographed an antenna for evaluation on the ground, and photographed the Strela-2 crane. The second was an internal spacewalk (IVA) in the depressurized Zvezda transfer compartment to replace one of the Zvezda hatches with a docking cone in preparation for the docking of the Poisk module later in 2009. This IVA lasted 12 minutes.

Barratt returned to Earth on October 11, 2009 after spending 198 days, 16 hours, and 42 minutes in space on Soyuz TMA-14 along with Padalka and space tourist Guy Laliberté.
