Millions of people around the globe will tune in today to watch the Americans take on Germany in each team's final group stage match at the World Cup in Brazil. But only three of those millions will be watching from space.

The space-watchers are three of the six crew members currently aboard the International Space Station -- two Americans and one German. Tensions are high between the three as the winner of the match will take first place in Group G. The United States needs either a draw or a win to advance. A loss would bring about a number of tiebreak scenarios.

"You better believe we'll be watching," NASA astronaut Reid Wiseman confirmed this week on NASA TV. "It's two against one up here, so I think the U.S. chances are pretty good."

To celebrate -- or loosen -- the friendly friction among crew members, the astronauts recently released another video showing how easy it is do a bicycle kick when gravity is not a factor.

The three also have a bet going. If the U.S. win, Steve Swanson -- the NASA astronaut and commander of Expedition 40 -- and Wiseman get to paint an American flag on the head of Alexander Gerst, the German astronaut with the European Space Agency.

If Germany takes the three points, the two American astronauts must shave their heads.
