ZZ-Mercury-Terminator-PIA12045.jpgMercurian Terminator (Natural Colors; credits: Lunar Explorer Italia)57 visiteThis high-resolution NAC image shows a view of Mercury's Dawn Terminator, the division between the sunlit dayside and dark nightside of the planet, as seen as the MESSENGER Spacecraft departed the Planet during the mission's second Mercury flyby.
This frame is just one of 195 images that make up the second NAC mosaic obtained following closest approach (see PIA11767). A mosaic is a series of images that form a larger picture, in this case a high-resolution view of a portion of Mercury's Northern Hemisphere. This image is also just one of the 1287 total images acquired during Mercury flyby 2.
Last week, all of the images (as well as data from MESSENGER's other instruments) collected during Mercury flyby 2 were made publicly available on NASA's Planetary Data System (PDS) website, giving scientists around the world access to this exciting new dataset.
Date Acquired: January 14, 2008
Image Mission Elapsed Time (MET): 108829034
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 590 meters/pixel (0,37 miles)
Scale: Moody is approx. 80 Km (about 50 miles) in diameter
Spacecraft Altitude: about 23.100 Km (approx. 14.300 miles)MareKromium

Coord. (centered): 8,3° South Lat. and 266,4° East Long.
Spacecraft altitude: 263,4 Km (such as about 164,6 miles)

SOU-SOL013-Sunset-NASA.gifSunset over Ares Vallis - Sol 13 (GIF-Movie - False Colors; credits: NASA)67 visiteCaption NASA:"Animation of the Martian Sunset.
This movie is made from 9 images of the twilight following Sunset over Ares Vallis. The images are enhanced in order to show the very subtle features in the haze, which are probably caused by layers that are slightly dustier than the surrounding air. The color is not the true color of the sunset - that is shown in other images.
At the beginning, the Sun is on the horizon just to the right of the frame, and it sinks during the next hour. At the time of the last image the sky is only 1% as bright as at the beginning, but the IMP can easily adapt to the darkness and return these pictures. Because there is so much dust extending high into the Martian Sky, the Sky stays bright for more than an hour after sunset".MareKromium

SOL1355-2P246653463EDNAVQWP2290L6M1-1.jpgAntenna Mast, Soil and "Sparkling Pebbles" - Sol 1355 (possible natural colors; elab. Lunexit)60 visiteInterpretazioni diverse, ma simili; entrambe razionali ed entrambe idonee a farci capire che "qualcosa" è successo, molto di recente, nei pressi di Spirit (quadrante in alto a Sx dell'Osservatore).
Le elaborazioni di Lunexit e del Dr Marco Faccin, come detto, sono MOLTO simili, a dispetto del fatto che sono state ottenute impiegando procedimenti sostanzialmente differenti.
Ora ci farebbe piacere vedere una elaborazione NASA del medesimo dettaglio ma...Forse è chiedere troppo.
Comunque sia, una cosa la si può dire senza timore di essere banali e/o scontati: se le logiche adottate per la trasformazione di un frame in b/n in un frame a colori sono simili (o, quanto meno, affini), lo strumento che permette la colorizzazione non è poi l'elemento decisivo ed i risultati finali restano comunque coerenti (pur nella loro - piccola - diversità).
Ora attendiamo i Vostri commenti e le Vostre valutazioni!MareKromium
