1. Lesson Objective:
Students will be able to describe the history and future of space exploration, including the types of equipment and transportation needed for space travel.

2. Today’s Agenda:
Space Exploration:
1. Past
2. Present
3. Future

3. The Past:
Until the 20th century, space exploration required looking through a telescope.

4. Telescope:
A telescope is an object designed to make distant object appear closer.

5. Technological advances skyrocketed starting in the 1950s because of the “Space Race”.

6. The Space Race:

8. What is a “Satellite”?

9. Satellites
A satellite: a man-made object that orbits a celestial body.
Uses: Gathering data (maps and weather), communication (cell phones and television).

10. Sputnik 1: October 4, 1957
The Soviet Union announces that they have launched a satellite into Earth’s orbit.
Sputnik broadcasts a beeping radio signal, and went around Earth once every 90 minutes.

11. Satellites:
Satellites have improved our ability to explore space, forecast the weather, and monitor changes to Earth’s surface.

12. Space Probes:
A space probe is an unmanned space craft that leaves Earth’s orbit and explores space.
The first space probe was called Pioneer 1 and was sent by the US in 1958.

14. Space Probes:
Pioneer 10 in 1972 was the first man-made object to travel through the asteroid belt.
The Voyager 2 probe was launched in 1977 and travelled past Jupiter in 1979 and past Uranus in 1986.

19. What is NASA?

20. NASA:
In 1958 the National Aeronautics and Space Administration (NASA) was founded.
NASA’s space program decides what equipment, accommodations, and transportation are needed for space exploration .
Since space is a cold, airless vacuum, NASA scientists equip space shuttles and suits with oxygen supplies.

21. Rockets:
Help space shuttles beat the force of gravity to get into space.

22. Space Shuttles:
Vehicles that carry humans into space.
