Over at Rocket Man Blog, there's a fantastic account of the many steps in getting to Mars. The animation by Dan Maas is available online using BitTorrent for the larger files. I'm currently trying to burn the DVD quality file onto a CD in SVCD format to play in a DVD player.
And speaking of web traffic, NASA has served over 15 TB in 78 hours. That comes out to over a solid 192 GB an hour, or 53 MB per second average, if my math is right. (It does appear that they're using the MB = 1e6 bytes rule, rather than MB = 220 bytes.)
