Neil Armstrong, Buzz Aldrin, Tom Hanks - all great men who've conquered outer space.
Soon we might be adding Sam Adams to that list because space beer is here.
Two experts, one from a microbrewery and the other from a space engineering firm, teamed up to create "Vostok 4 Pines Stout" - a prototype for the galaxy's first ever space beer.
They're hoping to cash in on the space tourism industry when it hits the mainstream, but getting crocked while cruising the cosmos isn't easy.
First off, you lose taste in space.
"Your face puffs out a little bit, your tongue swells up a little bit," said Dr. Jason Held of Saber Astronautics. "It's not extreme but it's kind of like having a bad head cold so we wanted to have a flavor that would be strong enough that would punch through that."
And that's not the only hurdle to getting your drink on in zero gravity.
"When you drink it the gas doesn't have anywhere to go, so when you want to burp you do what is called a 'wet burp' where the gas and the liquid come out together. It's rather uncomfortable," said Held.
It sounds like space beer is really flat, bitter beer - nevertheless, one small step for man, one giant leap from Tang.
