A really cool graphic of 50 years of space exploration. Full size: click here.

Personally, I think it's cool to look at the ones that haven't completed missions yet. Like New Horizons, launched in '08 with a dotted line for the year 2015, when it reaches Pluto.

A very neat music video about being lost in space. Love the graphics (and the song). 

Thanks to HC_Palmquist for showing it to me!
