The space shuttle Discovery has done a back-flip as it arrives at the international space station.
But it's not meant to show off. Instead, it let the crew of the space station take pictures of the shuttle's belly, to check for signs of damage.
Commander Steve Lindsey steered the nose up and slowly flipped
it over. Astronauts on the space station will send the digital pictures back to mission managers in Houston, who will pore over them.
NASA is concerned about damage that Discovery might have
suffered on liftoff.
The shuttle is docking at the space station today.
