  1. Study Guide • Optical Telescopes -Collects visible light/radiation. Space or land-based. reflecting/refracting • Reflecting Tele.-Optical; use mirrors • Refracting Tele.-Optical; use lenses • Hubble-Optical; reflecting; use mirrors; space-based. • Electromagnetic Spectrum-All wavelengths of radiation visible & non-visible • Non-optical telescopes -Collects non-visible light; most are space-based • Radio Telescopes -Non-optical, Non-visible light; land/space-based • Robert Goddard -Father of modern rocketry • Werner Von Braun -German scientist that helped develop the USA rocket program

  2. Rocket - using escaping gases to move • NASA -National Aeronautics & Space Administration; started directly because of Sputnik launch • Thrust -Force that propels a rocket • Artificial Satellite – a man-made body that orbits another body • Sputnik - First artificial satellite; cause of NASA creation • GEO -Orbit 36000km above Earth; travels at same speed as Earth to maintain its position • LEO-Orbit 1500km or less above Earth’s surface • GPS-Global Positioning System- innovation that allows an individual to pinpoint their exact location on Earth.

  3. MRI-Technology which provides images of the soft tissues of the body. • Space probes -Un-manned space vehicles that travel great distances; too far or too dangerous for humans • Yuri Gagarin -First man in space. • John Glenn -First American in space. • July 20, 1969- Eagle landed on the moon; Neil Armstrong first man to walk on the moon. • Space Shuttle -Reusable space vehicle that takes off like a rocket and lands like a plane. • Spinoffs -Technology which was originally designed for space exploration that is now used to benefit people on Earth.

  4. Name 3 technologies developed by NASA that we use in our everyday lives. DESCRIBE each one and how we use them.
