Pamela Ann Melroy (born September 17, 1961) is an American retired United States Air Force officer and NASA astronaut serving as the deputy administrator of NASA. She served as pilot on Space Shuttle missions STS-92 and STS-112 and commanded mission STS-120 before leaving the agency in August 2009. After serving as deputy program manager of Space Exploration Initiatives with Lockheed Martin,[1] Melroy joined the Federal Aviation Administration in 2011, where she was a senior technical advisor and director of field operations for the FAA's Office of Commercial Space Transportation.[2]

In 2013, she left the FAA and joined DARPA as deputy director of the Tactical Technology Office. She left the agency in February 2017.

In November 2021, Melroy was inducted into the United States Astronaut Hall of Fame at the Kennedy Space Center Visitor Complex. The ceremony, planned for May 2020, was delayed due to the COVID-19 pandemic.[3][4]

Early life and education

Melroy was born in Palo Alto, California, and graduated from Bishop Kearney High School in Rochester in 1979.[5] She received a Bachelor of Arts in Physics and Astronomy from Wellesley College in 1983.[6] She then earned her Master of Science in Earth and Planetary Science from the Massachusetts Institute of Technology in 1984. On May 18, 2008, Melroy received an honorary degree from Iona College in New Rochelle, New York.



Melroy was commissioned through Air Force ROTC, Detachment 365, in 1984. After completing a master's degree, she attended Undergraduate Pilot Training at Reese Air Force Base in Lubbock, Texas and was graduated in 1985. She flew the KC-10 for six years at Barksdale Air Force Base in Bossier City, Louisiana, as a copilot, aircraft commander and instructor pilot. Melroy is a veteran of the United States invasion of Panama and Operation Desert Shield/Desert Storm, with over 200 combat and combat support hours. In June 1991, she attended the Air Force Test Pilot School at Edwards Air Force Base, California. Upon her graduation, she was assigned to the C-17 Combined Test Force, where she served as a test pilot until her selection for the astronaut program. She has logged over 5,000 hours of flight time in over 50 different aircraft. Melroy retired from the Air Force in February 2007.

Selected as an astronaut candidate by NASA in December 1994, Melroy reported to the Johnson Space Center in March 1995. She completed a year of training and evaluation and was qualified for flight assignment as a shuttle pilot. Initially assigned to astronaut support duties for launch and landing, she also worked Advanced Projects for the Astronaut Office. She also performed CAPCOM duties in mission control. Melroy served on the Columbia Reconstruction Team as the lead for the crew module and served as deputy project manager for the Columbia crew survival investigation team. In her final position, she served as branch chief for the Orion branch of the Astronaut Office.

Melroy served as pilot on two flights (STS-92 in 2000 and STS-112 in 2002), and was the mission commander on STS-120 in 2007, making her the second woman to command a Space Shuttle mission (after Eileen Collins).[7] The STS-120 crew visited the station during Expedition 16, commanded by Peggy Whitson. Whitson was the first female ISS commander, making the STS-120 mission the first time that two female mission commanders were in orbit at the same time.[8][9]

She has logged over 924 hours (over 38 days) in space.[8]

Deputy administrator

Pam Melroy in 2022

In November 2020, Melroy was announced as a member of President-elect Joe Biden's presidential transition Agency Review Team, where her role was to support transition efforts related to NASA. This fueled speculation that Melroy was under consideration for the role of NASA Administrator in the Biden administration (then-Administrator James Bridenstine had indicated that he did not intend to stay in the role under Biden, even if asked).[11][12]

On April 16, 2021, The White House announced their intent to nominate Melroy to be NASA's deputy administrator, under former Democratic Senator Bill Nelson, who was nominated by the White House on March 19, 2021, to be the agency's administrator.[13] On April 22, 2021, her nomination was sent to the Senate.[14] The Senate Committee on Commerce, Science, and Transportation held a hearing on May 20, 2021, in which Melroy won strong bipartisan support to be deputy administrator. During her hearing, Melroy expressed support for extending the lifetime of the International Space Station, and said she would work closely with Administrator Bill Nelson in running the agency.[15]

On June 16, 2021, her nomination was reported out of the Senate Commerce Committee by voice vote, and the following day, her nomination was confirmed by the full Senate by unanimous consent.[16] On June 21, 2021, she was sworn into office by administrator Bill Nelson.[17]

Personal life

Melroy is married to Douglas Hollett, a geologist, who was previously acting assistant secretary for fossil energy in the United States Department of Energy and vice president for Southeast Asia exploration at Marathon Oil.[10]
