In 1996, he attended the flight test engineering course at the United States Air Force Test Pilot School, Edwards Air Force Base, California. Following graduation in 1997, he worked at the 418 Flight Test Squadron, testing C‐17 and C‐130 aircraft. In 1999, he moved to Cold Lake, Alberta, as an exchange officer with the Canadian Flight Test Center. In 2002, Hopkins was selected as an Olmsted Scholar by the George and Carol Olmsted Foundation. Following six months of language training at the Defense Language Institute in Monterey, California, he moved to Parma, Italy, in 2003, where he studied political science at the Università degli Studi di Parma. In 2005, Hopkins was assigned to the United States Air Force Rapid Capabilities Office at the Pentagon, where he served as a project engineer and program manager. In 2008, Hopkins was selected as a special assistant to the Vice Chairman of the Joint Chiefs of Staff, where he worked until he commenced astronaut training.
Hopkins was selected in July 2009 as one of 9 members of the 20th NASA astronaut class. He graduated from Astronaut Candidate Training in November 2011, which included scientific and technical briefings, intensive instruction in International Space Station systems, spacewalks, robotics, physiological training, T 38 flight training and water and wilderness survival training.
Expedition 37/38 (September 25 through March 10, 2014). On September 25, 2013, Hopkins launched from the Baikonur Cosmodrome in Kazakhstan along with Russian cosmonauts Oleg Kotov and Sergey Ryazanskiy. They were welcomed to the space station by Expedition 37 commander Fyodor Yurchikhin of Roscosmos, Karen Nyberg of NASA and Luca Parmitano of the European Space Agency. They were later joined by Expedition 39 commander Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) and flight engineers Russian cosmonaut Mikhal Tyurin and U.S. astronaut Rick Mastracchio. During his stay aboard the space station, Hopkins and Mastracchio conducted a pair of U.S. spacewalks to change out a degraded pump module for a total of 12 hours and 58 minutes. Hopkins, Kotov and Ryazanskiy returned to Earth on March 10, 2014, after 166 days in space. During the expedition, the crew completed 2,656 orbits of the Earth and traveled more than 70 million miles.
Hopkins is currently serving as Commander on the Crew-1 SpaceX Crew Dragon, named Resilience, which launched November 15, 2020. He will also serve as Flight Engineer on the International Space Station for Expedition 64.
