Current Space Exploration
• Space shuttle—reusable spacecraft for transporting people, satellites, and other materials to and from space– Launched like a rocket (on end)– Glides back to Earth like an airplane
• Space Stations—permanent places for humans to live and work in space– U.S. Skylab (1973-1979)– Soviet Mir (1986-2001)– Now, International Space Station (ISS) has
the support and cooperation of 16 countries

Future of Space Exploration
• Mars Exploration• Moon Exploration• Next Generation Telescope
– Has been names the James Webb Space Telescope after a NASA administrator
– Is being assembled now in Huntsville, AL– Hoped to launch as early as 2014—didn’t make it– To study first stars and galaxies in the universe– Able to see objects 400 x fainter that the best of modern
telescopes
