 Space Shuttle History
Rocket Propulsion

1. Rockets transport astronauts and materials into
space.
2. Animals such as monkeys, chimpanzee’s, dogs,
were first sent to make sure that the rockets were
safe for humans.

 Thrust is the force that pushes against the rocket,
causing it to move. (think of letting go of a balloon
that you’ve almost completely blown up).
 As the fuel on a rocket gets used up, parts of the
rocket’s propulsion system break off to make it
lighter (and therefore require less fuel).
Space Suits

 act as tiny spaceships that provide oxygen to
breathe, a cooling system to prevent overheating,
pressure control, and a communication systems.

Satellites

 Any body that orbits around another body in space.
 Natural Satellite – Earths Moon
 Artificial Satellite – Electronic Devices
Artificial Satellites

 Electronic devices that orbit Earth and relay
information
 communication satellites (TV, Internet), remote
sensing satellites(monitor forest fires, migrating
salmon, earthquakes, etc), and telescope satellites
(“MOST” informs us of dim stars as planets pass
them)
Satellites Orbits

 Satellites can travel in different types of orbits. The
further away the satellite is from the Earth, the longer it
will take to orbit:
 Low Earth Orbit: between 300-500km above the Earth.
These satellites travel around the Earth once every 90
minutes.
 Geosynchronous orbit: satellites placed above the equator a
distance of about 36 000km. These satellites take about 24
hours to make one orbit. Because they are rotating at the
same rate as the Earth, these satellites appear to stay in the
same place. Communication satellites are usually placed in
geosynchronous orbit.

Probes

 Probes are unmanned space crafts sent to other
celestial bodies to gather information about its
atmosphere and surface features.
 They can fly past, orbit, or land on these bodies.
 Do not need a crew and do not need to return to
earth
 All of the planets in our solar system have been
visited by a probe. Probes send images and
information directly back to the Earth.

Rovers “Robotic
Devices”

 Moveable probes designed to land on a planet
 have highly specialized programming so that they
can problem solve and are designed to withstand
extreme temperatures (freezing cold to blistering
heat).
 They are designed to work all day long and conserve
battery power at night.

 Mars Rovers
Optical Telescopes

 Two Types
- Refracting (use lenses)
- Reflecting (Use Lenses and Mirrors)
 Large observatories (labs that contain huge
telescopes) are typically built high on mountaintops
above most of the air so that they are not hindered
by atmospheric conditions (cloudy weather,
pollution, heat).
Example of a Large
Observatory Telescope

 Canada – France Hawaii Telescope (Figure 11.34
Page 419) – located on the volcano Mauna Kea in
Hawaii
Hubble Space Telescope

 In Earths Orbit
 With no air to spoil the view it allows us to see
objects far away in space

“How Hubble Sees”
Radio Telescopes

 large receivers that look like giant satellite dishes.
 collect wavelengths that are longer than visible light.
 How it works;
 1. receiver collects radio signals from a distant
object
2. radio signals are then converted to electric
impulses that are used to discover details about
celestial bodies
 You would not be able to find this information using
an optical telescope.
Very Large Array Radio
Astronomy Observatory

 Located in New Mexico
 Radio telescopes joined electronically to make one
giant radio telescope. (Interferometry)
 Used to study galaxies, black holes, nebulae, etc.
