Rocket• A vehicle or device that
contains all the substances needed to burn fuel and uses escaping gas from the burning of fuel to move
• YOU do not RIDE in a rocket, a rocket is the fuel source that lifts the space craft.
• Used to launch the space shuttle.
• Robert Goddard— “Father of Modern Rocketry”

Space Probe• A vehicle that carries scientific
instruments to planets or other bodies in space.
• They take pictures, temperature readings, and chemical readings of the atmosphere.
• Clementine (1994)-discovered evidence of water on moon
• Magellan (1989)—mapped 98% of Venus’ surface.
• The probes move around on the surface of any celestial body.
• Mars Rover is an example of a probe you hear about sometimes on the news.

Artificial Satellites
Any human-made object
placed in orbit around
a body in space
![Page 12: Space Exploration Tools](https://reader035.fdocuments.in/reader035/viewer/2022062520/56815f14550346895dcdde2c/html5/thumbnails/12.jpg)
What are some other uses for Artificial Satellites?
• Weather satellites• TV satellites• Telephone satellites• Military satellites

Space Shuttle
A reusable vehicle that takes off like a rocket and lands like an
airplane
![Page 14: Space Exploration Tools](https://reader035.fdocuments.in/reader035/viewer/2022062520/56815f14550346895dcdde2c/html5/thumbnails/14.jpg)
Space Shuttle• Used to carry astronauts
to repair satellites and construct the ISS.
• The first shuttle launched April 12, 1981.
• Final shuttle mission was March 9, 2011.
• The external fuel tank is not reused after flight, but is recycled.
• The solid rocket boosters break away and land safely in the ocean by way of parachute.

Telescopes• A telescope is an instrument that aids in the observation
of distant objects. • The first known telescopes were invented in the early
1600’s in the Netherlands.• There are two different types of telescopes:
– Reflecting: using mirrors; used in the Hubble telescope. This is the type used most widely today.
– Refracting: using glass lenses; used terrestrially and in astronomy.
• Telescopes need to be placed on hills and away from major cities due to light pollution.

A variety of telescopes
Reflecting Telescope: Mount Wilson Observatory
Refracting telescope: Nice Observatory

INTERNATIONAL SPACE STATION
A long-term orbiting vehicle that allows astronauts to live and work in
space
![Page 18: Space Exploration Tools](https://reader035.fdocuments.in/reader035/viewer/2022062520/56815f14550346895dcdde2c/html5/thumbnails/18.jpg)
International Space Station (ISS)
• Built in 1993• Research laboratory in space
to conduct experiments.• Used for microgravity
experiments and other research in space.
• Since the shuttle program was discontinued by NASA, American astronauts have to ride up with cosmonauts from other countries.
• There are currently astronauts in the space station.
• They tend to have missions that last about 6 months.
