My last post mentions that World Space Week begins today. Why today? Well, it's been 50 years since the start of the Space Age, launched with a little basket-ball sized satellite that beeped as it orbited the world on this day in 1957. Getting ready to launch, Sputnik looked like this:

EDIT: Today is also the third anniversary of the second flight of
SpaceShipOne, which garnered it the
Ansari X Prize (thanks to
shsilver for the reminder!). I love that they scheduled their winning lauch on Sputnik's anniversary!
SpaceShipOne is the white craft in the foreground; The Spirit of St. Louis is what used to make the first trans-Atlantic flight, and the orange craft is Chuck Yeager's "Glamorous Glennis" Bell X-1 rocket-plane, which he flew past the sound barrier for the first time in history on October 14, 1947 at an altitude of 45,000 feet.Chris
