What do you think would be required to make it possible for humans to survive on other planets? Make sure you describe the environmental conditions on at least two different planets.

Our task

Planet Mars

Mars is a terrestrial planet. It has a hard

rocky surface that you could walk on. Mars'

surface is dry and much of it is covered

with a reddish dust and rocks. Mars has

two permanent polar ice caps.

Mar’s surface

The Martian atmosphere consists of

carbon dioxide (95 percent), nitrogen

(2.7 percent), argon (1.6 percent),

oxygen (0.2 percent) and trace

amounts of water vapour and carbon

monoxide

Mar’s atmosphere

The surface gravity on Mars

is only about 38% of the

surface gravity on Earth. If

you weigh 100 pounds on

Earth then you would weigh

only 38 pounds on Mars.

Mars has two moons and

their names are Deimos

and Phobos.

Mar’s surface temperature can

usually range from about -120

degrease Celsius and to about

-30 degrease Celsius.

Planet Saturn

Saturn has a ring system that is divided into

nine continuous and three discontinuous

main rings (arcs), consisting mostly of ice

particles with a smaller amount of rocky

debris and dust. Sixty-two[19] known moons

orbit the planet; fifty-three are officially

named. This does not include the hundreds of

"moonlets" within the rings. Titan, Saturn's

largest and the Solar System's second largest

moon (after Jupiter's Ganymede), is larger

than the planet Mercury and is the only moon

in the Solar System to possess a significant

atmosphere

Saturn is approximately 75% hydrogen and

25% helium with traces of other substances

like methane and water ice.

 

Saturn's atmosphere, although similar to

Jupiter's, is much less interesting to look at

from a distance. But enhanced-colour

images (shown above) allow us to study the

bands across which run parallel to the

equator much like Jupiter's, indicating

violent winds.

'''About 74% of the surface gravity on

Earth. For instance, if you weighed 100 lbs.

on Earth, you weigh 74 lbs. on Saturn.

Saturn gravity

The temperatures below Saturn's clouds are much

higher than those at the top of the clouds.

The planet gives off about 2 1/2 times as much heat as

it receives from the Sun. Many astronomers believe

that much of Saturn's internal heat comes from

energy generated by the slow sinking of helium

through the liquid hydrogen in the planet's interior.

The temperature at the top of Saturn's clouds

averages -285° F (-175 °C). The core of Saturn is

much hotter, estimated at around 11,700 °C.
