Thanks for pointing it out Alex, I do have it ( 14th cover in the Viking section on the left side of the blog ). In fact I have some of the books twice, one always serving as reading copy
Nowadays I'm really looking forward to the release of some good DVDs ( MarsSociety is planning the release of The MarsUnderground ... and Spacecraft Films is considering to do several DVD sets on unmanned space exploration and I suggested them to do this per planet explored, so we might keep our fingers crossed and see the release of a 6-DVD set on Mars-exploration: 1 for the Mariners IV, VI, VII and IX, 1 for Vikings, 1 for Mars Pathfinder, 1 for Polar Lander + Climate Orbiter + MGS , 2 for MER ... wishful thinking for now )
