Martian surface Mensae contain thick glaciers covered by a mantle of rocky debris. 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
Albedo 0.39 track, "Albedo 0.39" is an atmospheric track building on waxing and waning synthesizer chords and arpeggios, while a voice, reputedly the album's engineer Keith Spencer-Allen, narrates various physical properties of the Earth, such as its mass, length of the year in various measurements, and, finally, its albedo. Mike DeGagne of Allmusic described the tracks as "mesmerizing trips of assorted rhythms that include elements of jazz and mild rock", that along with "Albedo 0.39", "the two parts of "Nucleogenesis" are among the strongest cuts that keep his cosmic theme from deviating, while the livelier "Pulstar" involves some impressive instrumental range and
