Randolph Bresnik

Bresnik launched aboard Soyuz MS-05 to the ISS on 28 July 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.

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 and his five crew mates launched from the Kennedy Space Center on 16 November 2009 ahead of an approximately two day rendezvous with the ISS, following witch 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 21 November 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 23 November 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 27 November 2009, returning Bresnik and his five crew mates, as well as Expedition 21 flight engineer Nicole Stott from the ISS.

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's family includes his wife, Rebecca Burgin of Pompton Plains, New Jersey, a son Wyatt (2006), and a daughter Abigail Mae (2009) who was born while he was in orbit during STS-129. This marked the second time a space traveler became a parent while on orbit; it first happened when Franz Viehböck's daughter was born while he was in space in 1991. His father is Albert 'Randy' Bresnik.

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.

In November 2002, he reported to Marine Aircraft Group 11 (MAG-11) as the Future Operations Officer. In January 2003, MAG-11 deployed to Ahmad al-Jaber Air Base, Kuwait. From Al Jaber, he flew combat missions in the F/A-18 with VMFA(AW)-225 in support of Operation Southern Watch and Operation Iraqi Freedom. Bresnik was the Operations Officer of VMFA-232 when he was selected for the astronaut program.

In January 2001, he returned to the USNTPS as a Fixed-Wing and Systems Flight Instructor, where he instructed in the F/A-18, T-38 Talon, and T-2 Buckeye. Bresnik returned to NSATS in January 2002 to continue flight test on the F/A-18 A-F as the Platform/Project Coordinator.

Bresnik was selected for the U.S. Naval Test Pilot School (USNTPS) at NAS Patuxent River, Maryland, and began the course January 1999. After graduation in December 1999, he was assigned as an F/A-18 Test Pilot/Project Officer at VX-23, the Naval Strike Aircraft Test Squadron (NSATS). While at Strike, Bresnik flew the F/A-18 A-D and F/A-18 E/F in all manners of flight test.

In May 1989, Bresnik received his commission as a Second Lieutenant in the U.S. Marine Corps from the Naval Reserve Officer Training Corps at The Citadel. After graduation he attended The Basic School (TBS) and Infantry Officers Course (IOC) at Marine Corps Base Quantico, Virginia. Following Aviation Indoctrination and Primary flight training in Pensacola, Florida, he entered Intermediate and Advanced flight training in Beeville, Texas, and was designated a Naval Aviator in 1992.

Bresnik graduated from Santa Monica High School in Santa Monica, California, in 1985. He then earned a Bachelor of Arts degree in Mathematics from The Citadel in 1989, and later a Master of Science degree in Aviation Systems from the University of Tennessee-Knoxville in 2002. He then graduated from the Air War College in 2008. Randy is the first graduate of The Citadel to fly in space.
