Doug Hemingway

Planetary Scientist and Space Systems Engineer


I have broad interests in the processes that drive the evolution and behaviour of planetary bodies of all kinds and what gives rise to all the diversity we see across our solar system and beyond. My research primarily involves geophysical modelling, with constraints coming in large part from spacecraft-based observations, especially relating to gravitational and magnetic fields. I work on problems related to magnetism, gravity, topography, elasticity/flexure/fracturing, heat production/transfer, and fluid dynamics. Some of my main research areas include: the interiors of icy moons, the magnetic histories of bodies like the Moon and Mars, and space weathering (click below for more information on each of these research areas).

About Me

I have a long-standing interest in space exploration and have enjoyed careers both in the space industry and in planetary science research. Prior to my doctoral studies, I was a space industry professional specializing in on-orbit robotic servicing for the International Space Station and the Hubble Space Telescope. I completed my PhD in August of 2015 in the Department of Earth and Planetary Sciences at the University of California Santa Cruz. My PhD advisors were Ian Garrick-Bethell and Francis Nimmo. My dissertation committee also included Gary Glatzmaier and Jasper Halekas. I then held postdoctoral fellowships at the Miller Institute for Basic Research in Science at the University of California Berkeley, where I was hosted in the Department of Earth and Planetary Science by Michael Manga and at the Carnegie Institution for Science's Earth and Planets Laboratory in Washington, DC, where I was hosted by Peter Driscoll. My continuing research in planetary science is supported through the Planetary Science Institute. Most recently, however, I have returned to the industry side of space exploration where I am now the Chief Scientist for Civil Space Business Development at Maxar Technologies, based in Palo Alto, California. It is my job to help connect space science exploration mission goals with Maxar's technical solutions in spacecraft, spacecraft subsystems, and robotics.

Most of what you need can be found in my CV, above. But here are some quick fun facts:

  • As a member of the robotics system team, I helped build the International Space Station
  • My undergrad research was on autonomous flying robots, which are now a thing
  • I helped develop a robotic servicing system for the Hubble Space Telescope
  • Antarctica is the only continent I haven't visited, though I would like to
  • I have taken over 44,000 digital photos, in 44 different countries
  • I am a licensed private pilot, but haven't flown in a while :(
  • I can solve a standard Rubik's cube in < 30 seconds
