Facts About International Day of Human Space Flight

- In order to reach Earth orbit at Vostok 1's altitude, a ship needs to hit 17,500 mph, or about 5 miles per second.

- The Vostok was a spherical capsule, designed to eliminate changes in center of gravity. In that way, the craft could assure comfort for its one-man crew no matter its orientation. What it wasn't designed to do was land with a human still on board.

- The total mission lasted just 108 minutes, and the trip once around the Earth at 17,500 mph (most of the way) took less than an hour and a half.

- A few weeks prior, a prototype of Gagarin's craft, the Vostok 3KA-2, completed one low-Earth orbit carrying a life-size dummy named Ivan Ivanovich and a dog called Zvezdochka.
