Moynihan worked as a flight surgeon at the University of Texas Medical Branch Wyle Laboratories. She was part of the Medical Operations team for the C-9 Familiarization Flight. She joined NASA in 2008. She manages the medical care for the occupants of interplanetary spacecraft. Around this time, Moynihan noticed that long duration astronauts were coming back with distinct visual changes. She has since been studying Spaceflight-Associated Neuro-Ocular Syndrome, and sent an optical coherence tomography scanner up to the ISS.She was part of the NASA twins study, monitoring astronaut Scott Kelly and his brother Mark Kelly. In 2016 she published practical considerations that must be taken for women astronauts on the International Space Station. She is concerned about reproductive viability, bone health, menopausal status and nutrition. Moynihan relies on telemedicine to provide health care to astronauts on board the International Space Station. The astronauts use a colour-coded ultrasound machine and make calls to Moynihan using a VoIP phone. During a sixth-month mission, one of the astronauts, who suffered with a history of knee injury, developed a persistent pain. This was assessed using ultrasound, where images were live streamed back to the planet Earth.
