Mercury: New Evidence for Water Ice at Mercury #39;s Poles http://WWW.GOODNEWS.WS
goodnews.ws Animation of Mercury #39;s and Earth #39;s revolution around the Sun. - MESSENGER image of Mercury with three visible colors mapped to 1000 nm, 700 nm, and 430 nm wavelengths. - Time-Lapsed Animation of a Mercury Day: Parts of Prokofiev crater (center) and Kandinsky crater (upper left side of Prokofiev) stay in darkness, making it possible for ice to persist on the surface. This time-lapsed animation represents nearly a full Mercury day. The illumination is derived from information provided by the Mercury Laser Altimeter. - MESSENGER Laser Altimeter: MESSENGER #39;s Mercury Laser Altimeter sends out laser pulses that hit the ground and return to the instrument. The amount of light that returns for each pulse gives the reflectance at that point on the surface. The amount of time it takes the pulse to make its trip indicates how far away that point on the surface is, allowing the topography to be mapped. Credit: NASA/Goddard Space Flight Center.
