On April 12, 1961, Yuri Gagarin became the first human being in space. Yuri was awesome and there's pretty much no way around that.
On April 12, 1981, the first space shuttle launched.
Today is April 12, 2011. It's been exactly thirty years since the start of the shuttle era and exactly 50 years since the start of the era of human spaceflight. Is it a bit of a bummer that we celebrate Space History Day (yes I made that up) preparing to say goodbye to the remaining space shuttles? Yeah it is.
