Introducing Luke Dones

Luke grew up in San Antonio, Texas and attended Harvard, where he majored in physics. He got his Ph.D. from the University of California, Berkeley. His thesis dealt with density waves in Saturn’s rings and the photometric properties of the rings as seen in Voyager images. He did a postdoc at NASA Ames Research Center in Silicon Valley and another postdoc at CITA in Toronto. He then returned to NASA Ames, where he worked on “soft money” for seven years. Since 1999 he has worked at the Boulder office of Southwest Research Institute, where he is currently a Principal Scientist.

Luke’s research interests are mainly focused in the outer solar system, particularly the orbital dynamics of comets, Kuiper Belt objects, and planetary satellites and rings, and the impact histories of icy satellites. He is a member of the Imaging Team of the Cassini mission to Saturn.

Introducing Kristin Block

This week, February 24-March 1, 2014, features Kristin Block. Kristin is a planetary scientist at the University of Arizona Lunar and Planetary Laboratory. Kristin works on spacecraft science operations, at the point where science and engineering meet. She is currently a Senior Targeting Specialist for the HiRISE (High Resolution Imaging Science Experiment) camera on NASA’s Mars Reconnaissance Orbiter, where she designs and commands observations of the surface, other spacecraft and landed assets, and the occasional passing comet. She’s proud to be part of the group that has won a NASA team award for its unprecedented images of Mars and new views into how the planet changes with time.

Kristin was a member of the Phoenix Mars Lander Optical Microscope team and has worked in laboratory-based astrobiology, researching the effects of lightning and meteorites on elements necessary for life. Planetary science is Kristin’s second career; before returning to grad school she performed and taught upright bass.

The other 51 weeks of the year, you can find Kristin at @MarsMaven.
