How do I tell the difference between all NASA's space shuttles?
Were there any substantive differences between the space shuttles?
What went wrong with the Columbia Space Shuttle? What exactly happened? What are some little known differences between the Space Shuttle Main Engines (SSMEs) and the RS-25 engines used on the SLS? Why didn't NASA build more space shuttles of the same design? What is the difference between astronauts and cosmonauts? Can space shuttle be used for commercial travel? I mean between countries? Why does the space shuttle require a fighter jet escort? Why doesn't NASA design new versions of the space shuttle? Could a Space Shuttle fly to and around the moon and back? Why not? Why were the solid rocket boosters on the Space Shuttle Discovery painted asymmetrically? Was NASA planning on building more shuttles after 1985? Why are sci-fi space vessels portrayed as part of the Navy, but not the Air Force? How are space rockets steered? What are the main differences between Star Trek and Star Wars? Does the U.S. currently have any means of putting astronauts in space? How do space rockets function in outer space? Could a space shuttle go to the moon? Which one is more powerful? SpaceX Falcon Heavy or NASA SLS? What are some of the theories as to the purpose of the US military space plane X-37B? What do astronauts of NASA think about Interstellar? What's the difference between an astronaut and a cosmonaut? What skills, experience, and attitudes are different between astronauts, cosmonauts, and other space-faring personnel from various nations? What material is the the exterior of the space shuttle made of? Why astronauts have a white and an orange-coloured space suit? What could have gone wrong with the SpaceX COTS Demo Flight 2/3? Why did the Apollo missions land two astronauts on the moon and not just one? What do astronauts do in outer space? How did scientists/engineers get the requirements of the first space suit given that no man had been to space before? What's the secret behind the Columbia space shuttle disaster during its re-entry into earth's atmosphere? How is the landing speed of a space shuttle controlled? What forms of propulsion offer the most promise for Interstellar spaceflight?
