Selected as an astronaut by NASA in May 2004. In February 2006, he completed Astronaut Candidate Training that

included scientific and technical briefings, intensive instruction in shuttle and International Space Station systems, 

physiological training, T-38 flight training, and water and wilderness survival training. Bresnik completed his first 

spaceflight on STS-129 in November 2009. From 2009 through 2011, Bresnik was assigned as the support astronaut on 

the Space Shuttle Closeout Crew tasked with strapping in the crew and closing and sealing the access hatch for flight. He

In 2010, Bresnik trained as a Cave-a-naut in the extreme environment training of the European Space Agency’s 

Cooperative Adventure for Valuing and Exercising human behavior and performance Skills (CAVES), in Sardinia, Italy. 

This was the first spaceflight analog of its type exploring, mapping, and living deep beneath the surface of the Earth. 

In September 2014, Bresnik, his three crew members and two habitat technicians tested technologies and training 

techniques for use aboard the International Space Station and future deep space exploration missions during NASA’s 

Extreme Environment Mission Operation (NEEMO 19). Bresnik was the Commander of NEEMO 19 team of Aquanauts. 

The mission was conducted in Florida International University’s undersea research habitat the Aquarius Reef Base, 

located six miles off the coast of Key Largo, Florida, and 62 feet below the surface of the Atlantic Ocean.

Spaceflight Experience:

STS-129 (November 16 through November 29, 2009). This was the 31st shuttle flight to the International Space Station. 

During the mission, the crew delivered two Express Logistics Carriers (ELC racks) to the space station, approximately 

30,000 pounds of replacement parts. Bresnik performed two spacewalks for a total of 11 hours and 50 minutes. The 

STS-129 mission was completed in 10 days, 19 hours, 16 minutes and 13 seconds, traveling 4.5 million miles in 171 

orbits, and returned to Earth bringing back with them NASA astronaut Nicole Stott following her tour of duty aboard the

the Soyuz 51S spacecraft. Bresnik was joined by ESA/ASI Astronaut Paolo Nespoli and Russian Cosmonaut Sergey

Ryazanskiy. During the mission the crew worked over 300+ scientific experiments and investigations, worked with 4

different visiting space vehicles, and conducted 4 spacewalks (3 USOS & 1 Russian). Bresnik performed 3 spacewalks

totaling 20 hours and 10 minutes. Bresnik’s spacewalk experience is now 5 EVAs for a total of 32 hours 0 minutes

outside in the void of space. The crew also took 808,126 photographs of the earth and inside the ISS during the two

expeditions. Expedition 52/53 was completed in 139 days, completing 2224 orbits of the earth and travelling 58,835,163
