Biographical Data

Christina M. Hammock
NASA Astronaut Candidate

PERSONAL DATA: Born in Michigan and considers her hometown to be Jacksonville, North Carolina. She has recently lived in Livingston, Montana. Her parents are Barbara Johnsen of Frederick, Maryland and Dr. Ronald Hammock of Jacksonville, North Carolina. Hammock enjoys backpacking, rock climbing, paddling, sailing, running, yoga, community service, photography and travel.

EDUCATION: Graduated from the North Carolina School of Science and Mathematics in Durham, North Carolina (1997). She attended North Carolina State University in Raleigh, North Carolina, where she earned a Bachelor of Science in Electrical Engineering (2001), a Bachelor of Science in Physics and an Master of Science in Electrical Engineering (2002).

SPECIAL HONORS: NASA Group Achievement Award, NASA Juno Mission Jupiter Energetic Particle Detector Instrument, 2012; Johns Hopkins University Applied Physics Laboratory, Invention of the Year nominee, 2009; United Sates Congress Antarctic Service Medal with Winter-Over distinction, 2005; NASA Group Achievement Award, NASA Suzaku Mission X-ray Spectrometer Instrument, 2005; Astronaut Scholar, Astronaut Scholarship Foundation, 2000 to 2001.

EXPERIENCE: Hammock has experience both in space science instrument development and remote scientific field engineering. Upon graduation, she worked as an Electrical Engineer at NASA Goddard Space Flight Center's Laboratory for High Energy Astrophysics, where she contributed to scientific instruments on several NASA missions studying cosmology and astrophysics. Hammock was a Research Associate in the United States Antarctic Program from 2004 to 2007. She completed a winter-over season at the Admunsen-Scott South Pole Station and a season at Palmer Station. While in Antarctica, she was a member of the Firefighting Teams and Ocean/Glacier Search and Rescue Teams. From 2007 to 2009, Hammock returned to space science instrument development as an Electrical Engineer at the Johns Hopkins University Applied Physics Laboratory's Space Department. She contributed to instruments studying radiation particles for NASA missions, including Juno and the Van Allen Probes. In 2010, Hammock returned to remote scientific field work with tours including Palmer Station in Antartica and multiple winter seasons at Summit Station in Greenland. In 2012, Hammock continued work at remote scientific bases, now with the National Oceanic and Atmospheric Administration (NOAA). She served as a Field Engineer at NOAA's Global Monitoring Division Baseline Observatory in Barrow Alaska, and then as Station Chief of the American Samoa Observatory.

NASA EXPERIENCE: Hammock graduated from the NASA Academy program at Goddard Space Flight Center (GSFC) in 2001. She worked as an Electrical Engineer in the Laboratory for High Energy Astrophysics at GSFC from 2002 to 2004.

Hammock was selected in June 2013, as one of eight members of the 21st NASA astronaut class. She is currently in Astronaut Candidate Training that includes scientific and technical briefings, intensive instruction in International Space Station systems, Extravehicular Activity (EVA), robotics, physiological training, T-38 flight training, and water and wilderness survival training.
