Ray system they have been identified on Mars in infrared images taken from orbit by "2001 Mars Odyssey"s thermal imager. Rays appear at visible, and in some cases infrared wavelengths, when ejecta are made of material with different reflectivity (i.e., albedo) or thermal properties from the surface on which they are deposited. Typically, visible rays have a higher albedo than the surrounding surface. More rarely an impact will excavate low albedo material, for example basaltic-lava deposits on the lunar maria. Thermal rays, as seen on Mars, are especially apparent at night when slopes and shadows do not influence the infrared energy emitted
Albedo (role-playing game) using near-future and far-future weaponry, in the same vein as "Tom Clancy's Rainbow Six" and other "techno thrillers", as well as using genetically-engineered people as a morality play for 20th century geopolitics. Albedo (role-playing game) Albedo is a role-playing game based on Steve Gallacci's and "Birthright" storylines from the comic anthologies "Albedo Anthropomorphics" and "Critters". "Albedo: Platinum Catalyst" is characterized by the notable player-controlled troupe of characters, the main character and four supporting retinue. The main character is more fleshed out than his supporting characters which typically have 3 stats (species, morale, job description) and a weapon. Morale is a
