NASA career

Selected as a mission specialist by NASA in July 2000, McArthur reported for training in August 2000.[2] She trained at the Carter training facility. Following the completion of two years of training and evaluation, she was assigned to the Astronaut Office Shuttle Operations Branch working technical issues on shuttle systems in the Shuttle Avionics Integration Laboratory (SAIL). McArthur then served as the Crew Support Astronaut for the Expedition 9 Crew during their six-month mission aboard the International Space Station. She also worked in the Space Station and Space Shuttle Mission Control Centers as a Capsule Communicator (CAPCOM). In 2006, McArthur was the capsule communicator (capcom) for STS-116. She was also the EVA capcom for the STS-117 mission in 2007.


Megan McArthur was a member of the STS-125 mission to service the Hubble Space Telescope. McArthur was the ascent and entry flight engineer and was the lead robotics crew member for the mission. The mission which lasted almost 13 days[2] was McArthur’s first trip into space. In a pre-flight interview, she put it as: “I’ll be the last one with hands on the Hubble Space Telescope.”[3]
