Answers
Dr. William K. Hartmann is known internationally as a scientist, writer, and painter. His research involves origin and evolution of planets and planetary surfaces, and the small bodies of the solar system.
Specific research topics have included studies of cratering on the moon and Mars, leading the development of the currently most-accepted model for origin of the moon, telescopic observations of asteroids and satellites, participation in the Mariner 9 and Mars Global Surveyor Mars missions. (See Science Research for more details).
Hartmann has authored three college level textbooks in astronomy and planetary science, all of which have been published in multiple editions, and roughly 200 technical papers.
He has also published a number of popular non-fiction, illustrated books on astronomy, earth science, and the Sonoran Desert. In 1997 he published a novel about Mars, and in 2002, a novel about the Southwest. (See Writing page for more details).
Hartmann's paintings of astronomical themes have appeared in these books and in magazines and exhibits in the U.S., Russia, Japan, and Europe. He has twice had paintings commissioned by the NASA Fine Arts Program. (See Painting page for more details).
In 1992-95 he headed an effort for the Planetary Society and National Science Teachers Association to incorporate planetary science materials into the grade 6-12 curriculum. His book of lessons, "Craters!" was published in 1995 by the NSTA.
Hartmann has also served as a photo-analyst on the U.S. House of Representatives Select Committee on Assassinations and on the U.S. Air-Force study of the UFO problem under Dr. Edward Condon, University of Colorado.
