06-C_Mars04_Panorama1.jpgMars panorama from Mars-4 (1)97 visiteThe first in an armada of four spacecrafts launched in 1973, Mars-4 failed to enter orbit. During its flyby - on February 10, 1974 -, it returned 12 photographs from the 52mm "Vega" phototelevision camera, all through the red filter. It also returned 2 panoramas from the optical-mechanical cameras. Image data was returned digitally by pulse position modulation.

07-C_Mars04_Panorama2.jpgMars panorama from Mars-4 (2)108 visiteTwo optical-mechanical linear cameras swept out panoramas of Mars as the spacecraft passed by.
These were very similar to cameras later flown on Venera-9 and 10 Orbiters, but one of the Mars versions had a photomultiplier tube sensitive to infrared.
Apparently, no infrared panoramas were received from Mars-4 or Mars-5.

Venus-PIA10124-PCF-LXTT-IPF.jpgApproaching Venus (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)79 visiteCaption NASA:"The Planet Venus is enshrouded by a Global Layer of Clouds that obscures its surface to the MESSENGER Dual Imaging System (MDIS) cameras. This single frame is part of a color sequence taken to help the MESSENGER team calibrate the camera in preparation for the spacecraft's first flyby of Mercury on January 14, 2008. Over the next several months the camera team will pore over the 614 images taken during this Venus encounter to ascertain color sensitivity and other optical properties of the instrument. These tasks address two key goals for the camera at Mercury: understanding surface color variations and their relation to compositional variations in the Crust, and ensuring accurate cartographic placement of features on Mercury's Surface.
Preliminary analysis of the Venus Fly-By images indicates that the cameras are healthy and will be ready for next January's close encounter with Mercury".
Nota Lunexit: questo NASA - MESSENGER color-frame è stato prima riportato sulla Scala dei Grigi, poi ingrandito, riprocessato e poi ricolorizzato in Colori Naturali Assoluti. Il risultato è un pò bizzarro, probabilmente poco realistico, ma sen'altro suggestivo. Giudicate Voi!MareKromium

ZO-Mercury03_Messenger-208855main_half_merc_350.jpgCrescent Mercury56 visiteAs NASA’s MESSENGER neared Mercury on January 14, 2008, the Spacecraft took this image of the Planet’s full crescent.
The image shows portions of Mercury previously seen by Mariner 10, but when Mariner 10 flew by the Planet at each of its encounters, the Sun was nearly overhead. For this MESSENGER flyby, in contrast, the Sun is shining obliquely on Regions near the day/night boundary (called the Terminator) on the right-hand side of the crescent, revealing the surface topography.
This image illustrates how MESSENGER, during its future flybys and subsequent orbital mission, will teach scientists much about the portion of Mercury already imaged by Mariner 10.MareKromium
