Martian surface Martian surface The study of surface characteristics (or surface properties and processes) is a broad category of Mars science that examines the nature of the materials making up the Martian surface. The study evolved from telescopic and remote-sensing techniques developed by astronomers to study planetary surfaces. However, it has increasingly become a subdiscipline of geology as automated spacecraft bring ever-improving resolution and instrument capabilities. By using characteristics such as color, albedo, and thermal inertia and analytical tools such as reflectance spectroscopy and radar, scientists are able to study the chemistry and physical makeup (e.g., grain sizes, surface roughness, and rock
Albedo One by Tachyon Productions and was in an A5 size format. From issue 13, 1996, the magazine moved to a larger A4 format and was published by Albedo One Productions. The move to new publisher and format was motivated, according to the editors, "in an effort to gain better distribution, more advertising and put a little jizz into the magazine.".
