  1. Part I: Investigating the Past

  2. World’s First Accurate Star Map • Who: Hipparchus • When: Circa 130 B.C. • Equipment: His own knowledge of mathematics and observations of the movements of the stars.

  3. Galileo & the Telescope • Who: Galileo Galilei • When: 1609 • Equipment/Technology: Making improvements on the first telescope, was able to magnify objects 3-30 times; used this telescope to discover 4 of Jupiter’s moons, the cycles of Venus, and was one of the first to study sunspots

  4. First Satellite to Orbit Earth • Who: The Sputnik Satellite; USSR • When: October 4, 1957 • Equipment/Technology: A satellite about 58 cm in diameter, about 83.6g weight, travelled 29,000 km/hr (96 minute orbit), beeping radio beacon

  5. First Human in Orbit • Who: Yuri Gagarin; USSR • When: April 12, 1961 • Equipment/Technology: USSR-developed Vostok 1 spacecraft

  6. Apollo Moon Landing • Who: NASA, Neil Armstrong, Buzz Aldrin • When: July 20, 1969 • Equipment/Technology: Apollo 11 space craft with Moon lander, “Eagle”

  7. Voyager 1 Space Probe • Who: NASA • When: September 5, 1977 • Equipment/Technology: U.S. robotic space probe, 722 kg, farthest man-made object in space, first to leave our solar system, detailed photo study of Jupiter/Saturn systems, also carries a golden record with details of life on Earth in case it is discovered by intelligent life.

  8. Hubble Space Telescope • Who: NASA • When: Launched 1990 • Equipment/Technology: Launched from a shuttle; array of cameras capable of taking photos, such as the Hubble Ultra Deep Field, which is the deepest look into the universe (image contains ~ 10,000 galaxies and goes back approximately 13 billion years); allows scientists to take sharp images of distant objects in space

  9. International Space Station • Who: American, European, Japanese, Russian space programs • When: In orbit assembly began in 1998 and was scheduled to end in 2012 (has been extended) • Equipment/Technology: Largest artificial satellite to orbit Earth, can be seen from the ground with naked eye, has a microgravity environment for carrying out research

  10. Virgin Galactic Commercial Space Flight • Who: Richard Branson, Virgin Group • When: ~ 2010 testing, future flights • Equipment/Technology: $200,000 per ticket, 6 passenger 2-pilot craft, SpaceCraft Two is carried atop a carrier aircraft called White Knight II, will go 100km into space for 6 minutes of weightlessness
