Happy Yuri's Night/STS-1 Day

[ebenbrooks]

Today is the 55th anniversary of Vostok-1, the first human space flight, on which Yuri Gagarin of the USSR became the first human being in space. It is also the 35th anniversary of STS-1, the first space shuttle launch, specifically of Space Shuttle Columbia.

So celebrate space flight today! Maybe go watch some videos over at SciShow Space, or watch a good space movie like 2001: a Space Odyssey or The Right Stuff. Or Star Trek.
