Mars5-C_Mars05_3_Color1.jpgColor shots from Mars-5 (1)88 visiteMars-5 entered an elliptic Martian orbit on February 12, 1974. Nearly synchronized with the rotation of the Planet, its two phototelevision cameras could be commanded to take 12 pictures during each close approach. The "Vega" camera used a wide area 52mm lens with color filters, the "Zulfar" camera used a telescopic 350mm lens and long-pass orange filter.
Images were transmitted in a rapid 220-line mode, and then selected pictures were retransmitted at 880 or 1760 line resolution.

04-C_Mars03_Mountains.jpgMars Mountains82 visiteContrary to some reports, the phototelevision cameras on Mars-3 were functional after the dust storm subsided, in December. At least four photographic surveys have been reported (December 12 and 14, February 28 and March 12). Images were returned by pulse-code modulation over the decimeter-band telemetry channel, after the centimeter-band pulse-position modulation system failed.
The decimeter transmitter suffered from intermittant failures and was used very cautiously. Only after important science data was gathered, a small number of images at LR were transmitted (using a 256-line mode). The color image of Mars (picture n. 1) is a composite from the 52 mm camera, using its program of cycling red, green and blue glass filters.

01-Mars.jpgMars, from "Mars 3": the Red Planet! (2)68 visiteQuesta Galleria costituisce un tributo a tutti quei Pionieri (Ingegneri, Astronomi, Astronauti, Tecnici e Collaboratori vari) che lavorarono nel silenzio oltre la "Cortina di Ferro". Costoro, diciamo "per mera sfortuna", mancarono l'obbiettivo di far scendere due Astronauti sulla Luna, ma furono tuttavia capaci, a costo di sacrifici immensi (e, a quanto si dice, di innumerevoli vite), di portare alcune Sonde (e svariati Landers) sulla Luna, nello Spazio di Marte, sul Pianeta Rosso e su Venere, raccogliendo sia preziose informazioni scientifiche, sia immagini di grandissimo valore storico e di enorme impatto visivo.
