1. Unit 4: Astronomy Chapter 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. Sec 1: Key Terms Rocket Thrust Velocity Orbital velocity
Escape velocity
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. Sec 2: Key Terms
Satellite

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. Sec 3: Key Terms Space shuttle Space station Space probe Rover
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. Sec 4: Key Terms Vacuum Microgravity Space spinoff Remote sensing
Geostationary orbit
