American astronauts Steve Swanson and Reid Wiseman shaved their heads when they lost a bet with fellow ISS astronaut Alexander Gerst post U.S. lost to Germany in the World Cup.
According to the bet, if the U.S. won, Gerst would allow Swanson and Wiseman to paint the U.S. flag on his head, but if Germany won, then Swanson and Wiseman would shave their head, CBS News reported.
Mission Control suggested that the American astronauts look on the bright side, pointing out that bald was more aerodynamic when flying.
Wiseman jokingly thanked for the shave through twitter.
