− | <p>How much longer will we not have a quality photomap of the Moon? Despite the Moon’s nearness to Earth, and the dozens of space missions that we have sent there, the Moon has no adequate global image map. This is a section of the newest photomap (still under construction) that uses some of the oldest lunar orbital images. The [http://astrogeology.usgs.gov/ Astrogeology Branch] of the US Geological Survey in Flagstaff, Arizona is creating a mosaic of the lunar nearside using the high resolution (few hundred meters, not the coarse res shown here) Lunar Orbiter IV photos of 1965. This nearside mosaic will have nearly constant resolution and sun angles, but there is only lower resolution images for the eastern area of the Moon where Orbiter IV malfunctioned. A second photomoasic of the entire Moon was created from Clementine images. That [http://astrogeology.usgs.gov/Projects/Clementine/images/albedo.simp750.jpeg image map] is widely available but has the significant disadvantage of having an illumination angle that varies from zero at the poles to full Moon at the equator. The only other hemisphere-wide photographic lunar [http://www.lpod.org/archive/archive/2004/03/LPOD-2004-03-23.htm mosaic] was created by Pablo Lonnie Pacheco Railey who used Photoshop to combine hundreds of photos from the Earth-based [http://www.lpod.org/archive/LPOD-2004-08-11.htm Consolidated Lunar Atlas]. Finally, the European Space Agency probe, [http://www.esa.int/esaSC/120371_index_0_m.html SMART-1], appears to be imaging the entire nearside (and farside??), but I do not know if the look angles will be consistent so that a new global mosaic can be contructed from them. Hopefully, the SMART-1 images will be cataloged and released soon. And when the US, Chinese and Indian probes reach the Moon in 2008 or so will they finally collect data to generate a global, high resolution, constant sun angle, digital imagemap of the Moon? I hope so.</p> | + | <p>How much longer will we not have a quality photomap of the Moon?
