  1. Unit 4: AstronomyChapter 13: Exploring Space Big Idea: Scientists have learned much about the solar system through various types of space missions

  2. 4 Sections • The Science of Rockets • The Space Program • Exploring Space Today • Using Space Science on Earth Mrs. Lee - Ch 13

  3. Sec 1: The Science of Rockets KEY CONCEPTS • Rocket technology originated in China hundreds of years ago & gradually spread to other parts of the world • A rocket moves forward when gases shooting out the back of the rocket push it in the opposite direction • The main advantage of a multistage rocket is that the total weight of the rocket is greatly reduced as the rocket rises Mrs. Lee - Ch 13

  4. Rocket Thrust Velocity Orbital velocity Escape velocity Sec 1: Key Terms Mrs. Lee - Ch 13

  5. Sec 2: The Space Program KEY CONCEPTS • The space race began in 1957 when the Soviets launched the satellite Sputnik I into orbit. The United States responded by speeding up its own space program • The American effort to land astronauts on the moon was named the Apollo program Mrs. Lee - Ch 13

  6. Satellite Sec 2: Key Terms Mrs. Lee - Ch 13

  7. Sec 3: Exploring Space Today KEY CONCEPTS • NASA has used space shuttles to perform many important tasks. These include taking satellites into orbit, repairing damaged satellites, & carrying astronauts & equipment to & from space stations • A space station provides a place where long-term observations & experiments can be carried out in space Mrs. Lee - Ch 13

  8. Sec 3: Exploring Space Today (cont’d) • Each space probe has a power system to produce electricity, a communication system to send & receive signals, & scientific instruments to collect data & perform experiments Mrs. Lee - Ch 13

  9. Space shuttle Space station Space probe Rover Sec 3: Key Terms Mrs. Lee - Ch 13

  10. Sec 4: Using Space Science on Earth KEY CONCEPTS • Conditions in space that differ from those on Earth include near vacuum, extreme temperatures, & microgravity • The space program has developed thousands of products that affect many aspects of modern society, including consumer products, new materials, medical devices, & communications satellites Mrs. Lee - Ch 13

  11. Sec 4: Using Space Science on Earth (cont’d) • Satellites are used for communications & for collecting weather data & other scientific data Mrs. Lee - Ch 13

  12. Vacuum Microgravity Space spinoff Remote sensing Geostationary orbit Sec 4: Key Terms Mrs. Lee - Ch 13
