12.3 SPACE-BASED OBSERVATION

Kyle & Ish

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

Rocket diagram

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
