Bresnik was selected by NASA in May 2004 as an astronaut candidate. He was one of two pilots chosen in the Astronaut Class of 2004. In February 2006, he completed Astronaut Candidate Training. Bresnik participated in the first analogue ESA CAVES mission in September 2011, staying underground and exploring the caves for 6 days, simulating Mars mission technologies.

On June 10, 2014, NASA announced that Bresnik would command the NEEMO 19 undersea exploration mission aboard the Aquarius underwater laboratory, which began on September 7, 2014, and lasted seven days. Bresnik was the lead astronaut assigned to the closeout crew for the final STS-135 launch in the Shuttle program.

In September 2008 NASA announced that Bresnik was assigned as Mission Specialist STS-129, a shuttle mission to the International Space Station. The mission was then slated to launch in October 2009 aboard Space Shuttle Discovery, although this was later pushed back to November 2009 aboard Space Shuttle Atlantis.

Bresnik and his five crew mates launched from the Kennedy Space Center on November 16, 2009, ahead of an approximately two day rendezvous with the ISS, following which the crew joined the Expedition 21 crew, Commanded by Belgian ESA astronaut Frank De Winne. The main objective of STS-129 was to deliver and install the first two of four ExPRESS Logistics Carriers (ELCs) to the ISS. ELCs are exposed pellets installed on the outboard truss of the ISS intended to support vacuum capable payloads such as scientific experiments built for operations on the outside of the station or for holding spare parts.

Bresnik participated in the second and third EVA of STS-129. On November 21, 2009, Bresnik stepped outside the station with veteran spacewalk Michael Foreman, the two spent six hours and eight minutes outside of the ISS installing a piece of equipment called the Grappling Adapter to On-Orbit Railing (GATOR) on the European Columbus, installing a wireless video system on the outside of the station and setting up a cargo attachment system. Bresnik's second spacewalk took place on November 23, 2009, and was alongside NASA astronaut Robert Satcher. Satcher and Bresnik spent five hours and 42-minutes outside the station installing a similar cargo attachment system to the one on the last spacewalk, but on the opposite side of the station, installing the MISSE-7 experiment and transferring a high pressure gas tank.

STS-129 returned to Earth on November 27, 2009, returning Bresnik and his five crew mates, as well as Expedition 21 flight engineer Nicole Stott from the ISS.

Bresnik launched aboard Soyuz MS-05 to the ISS on July 28, 2017, and served as Flight Engineer for Expedition 52, and as ISS Commander for Expedition 53.

On October 5, 2017, Bresnik performed his third spacewalk, along with Mark Vande Hei. The spacewalk replaced the gripping mechanism on Canadarm2, the latching end effector A, or LEE-A. Spacewalk duration was 6 hours and 55 minutes. On October 10, 2017, Bresnik and Vande Hei completed the second EVA of the mission. They lubricated the newly installed end effector and replaced cameras, and the duration was 6 hours and 26 minutes. On October 20, 2017, Bresnik and Joe Acaba performed an EVA to continue with the lubrication tasks, and to install more cameras. The duration was 6 hours and 49 minutes.

Bresnik returned to Earth on December 14, 2017. The Soyuz MS-05 landed on 8:38 UTC. The duration of the mission was 138 days, 16 hours, 56 minutes and 37 seconds.
