Tennis was played in outer space for the first time ever on Tuesday. Equipped with USTA Net Generation foam balls and small racquets, four astronauts in the International Space Station got to play a competitive match while orbiting the earth.
"Our match in space was pretty challenging due to the fact that we are in a microgravity environment," ISS Commander of Expedition 56 Andrew "Drew" Feustel said. "We did have a net, but the rules allowed the ball to go over or under the net. Also, there was no requirement for us to stay on the ground, so to speak, so we had the freedom to play on the walls, ceiling or floor."
