The different Space Shuttles. The Columbia first, followed by the Challenger, the Discovery and the Atlantis and then the Endeavour. These machines are just so incredibly cool, I’ve been fascinated by them since I was a kid. Which one’s your favorite? Mine’s the Space Shuttle Atlantis. Have a great day! / Goodnight! © NASA [[]]
