What you will learn What a probe is and what have they
done All about rovers and how they made
it to Mars Rockets Space shuttle program and why it is
important International space station and what
they have done

Probes A space vehicle
sent to other celestial bodies
Travels places humans can’t go
Used to analyze distant objects
Most aren’t designed to return to Earth
Mariner 10: launched Nov 3 1973First to travel to Mercury

Probes (cont.) Soviet Union landed
probes on Venus (communication only lasted half an hour)
Probes sent past the furthest planets in the solar system
Can orbit, fly past or land on planets
Probe sent by Soviet Union

Rover Robot space
explorers Testing the surfaces
for evidence of life and water
1 out of every 3 missions on mars is a success
Send information back to Earth
Only rest at night
Mars Rover

Rovers (cont.) Mars rover has found
water on the surface of the planet
Operate in extreme temperatures
Conduct experiments in meteorology, geology and biology
Took 6 to 8 months to get to mars
Launched June 10 and July 7 and landed January 3 and January 24

Rockets System used to
transport astronauts into space
Thrust- force that pushes against the rocket
Parts of the propulsion system are released to make the body lighter

Space shuttle program Reuses the parts of the
rocket that fall from the propulsion system.
The rockets are designed to be reusable.
It was started 30 years ago
Most of the rocket parts fall into the ocean

International space station 350Km about earth Nemours experiments
in micro gravity Micro gravity is the
condition of weightlessness in space.
16 countries including Canada, Russia, USA
