Fun in Zero-G: Weightless Photos from Earth and Space

Koichi Wakata: Green Apple in Space

Weightlessness is arguable one of the most amazing parts of space travel, despite the physical and engineering challenges it poses for astronauts. And it can be a lot of fun, too. Check out some amazing photos of astronauts and civilians in weightlessness in this Space.com gallery. Here: This image of a green apple was taken by JAXA astronaut Koichi Wakata aboard the International Space Station on Feb. 6, 2014. Wakata tweeted the haiku: “Smell of the Earth, from the fresh green apples, just arrived on Progress.
