  1. 1. Ch. 22 Notes SPACE EXPLORATION
  2. 2. EARLY SPACE MISSIONS: <ul><li>*Sputnik I – (1957) Soviet Union sent the 1 st artificial satellite into orbit for 3 months. </li></ul><ul><li>*Yuri Gagarin – (1961) 1 st human in space. Marked beginning of the “Space Race” between Russia and U.S. </li></ul><ul><li>*Space Race - (1961) U.S. enters the “Space Race” with Soviet Union to see who is first to the moon. </li></ul>
  3. 3. THE SPACE RACE: <ul><li>*PROJECT MERCURY – (early 1960’s) U.S. goal to reach the moon. </li></ul><ul><ul><li>Alan Shepard – (1961) 1 st U.S. citizen to pilot a craft to space and back. </li></ul></ul><ul><ul><li>B) John Glenn – (1962) 1 st U.S. citizen to orbit Earth. </li></ul></ul>
  4. 4. THE SPACE RACE (CONT.) <ul><li>*PROJECT GEMINI - (1960’s) Next step in the U.S. reaching the moon. Demonstrated a connection between two spacecrafts in orbit. </li></ul><ul><ul><li>Mercury mission – series of robotic probes sent to the moon. </li></ul></ul><ul><ul><li>Ranger mission – proved that we could get a man to the moon. </li></ul></ul><ul><ul><li>Surveyor mission – proved that man could land on the lunar surface. </li></ul></ul><ul><ul><li>D) Lunar Orbiter mission – photographed possible landing sites on the lunar surface. </li></ul></ul>
  5. 5. THE SPACE RACE (CONT.) <ul><li>*PROJECT APOLLO - series of U.S. unmanned and manned missions to the moon. </li></ul><ul><ul><li>Apollo 11 – (1969) Neil Armstrong was 1 st to set foot on the moon. </li></ul></ul><ul><ul><li>B) Apollo 15, 16, & 17 – (1970’s) Use of a lunar roving vehicle to explore moon’s surface. </li></ul></ul>
  6. 6. EXPLORATION PAST THE MOON: <ul><li>*VOYAGER SPACE PROBES – (1977) “Info- Gathering” crafts sent to explore space beyond moon’s orbit. </li></ul><ul><li>A) Voyager I – Has reached the outer edges of our Solar System (into Kuiper Belt) and still transmitting. </li></ul><ul><li>B) Voyager II – Is on its way past Neptune and Pluto (headed for Kuiper Belt) and </li></ul><ul><li>still transmitting. </li></ul>
  7. 7. MODERN SPACE EXPLORATION: <ul><li>*SPACE SHUTTLE – (1980) Reusable craft that transports satellites, astronauts, and other materials to and from space. Launched via rockets and glides back to Earth. </li></ul><ul><li>*SPACE STATION – Permanent outpost in orbit that provides living quarters and workspace for astronauts. </li></ul><ul><li>A) Skylab – (1973) Used to study effects on humans in space. </li></ul><ul><li>B) Mir – (1980’s) Used to study effects on humans living in space for long periods. Used with </li></ul><ul><li>space shuttle. </li></ul>
  8. 8. MODERN SPACE EXPLORATION (CONT.) <ul><li>*HUBBLE SPACE TELESCOPE – (early 1990’s) sent into space to transmit info and photos back to Earth. </li></ul><ul><li>*INTERNATIONAL SPACE STATION – (1997) More than a dozen nations cooperated to send an outpost into orbit. Used with space shuttle to study docking missions and for lab experiments. </li></ul>
  9. 9. MODERN SPACE EXPLORATION (CONT.) <ul><li>*Mars Rover missions – (1990’s to present) NASA & independent companies have sent several crafts to study Mars’ atmosphere and surface. </li></ul><ul><li>*Stellar Space Probes – (present) space probes are being sent to study other planets up close. </li></ul>
  10. 10. FUTURE SPACE EXPLORATION <ul><li>*Lunar Studies – NASA is looking once again at the moon. </li></ul><ul><li>A) Sees the moon as a possible docking and refueling site for deep space missions to Mars and beyond. </li></ul><ul><li>B) May also be a site for a future space station or colonization by humans. </li></ul><ul><li>C) May eventually be used as a stepping stone to travel outside our solar system. </li></ul>
