Living on

planets

By Ruby and Jade

Our

Task Our task is to see what

will be required if we

were to live on any planet in our solar system.

The surface of Mars appears to be made up

of basalt. Some evidence suggests that

a portion of the planets

surface is more silica-

rich than normal basalt.

And maybe similar to

some rocks on earth;

Research also suggests

that Mars is covered

with fine grained iron.

Gra

vity The surface gravity of

mars is only about 38% of earths gravity.

Wate

r

Mars has two permanent polar ice

caps. The polar caps at both poles

consists mainly of water ice.

Frozen carbon dioxide accumulates

a thin layer of water ice, about 1

meter thick on the north cap in the

northern winter only. While the

south cap has a permanent dry ice

cover about 8 meters thick. The

northern polar cap has a diameter

about 1000km during the northern

Mars summer which is spread

evenly, the cap would be 2km

thick. The Southern polar cap has a

diameter of 350km and a thickness

of 3km.

The Minimum temperature of Mars is

around -87C . And the

Maximum is around -5C.

Mars is colder than earth, Venus and Mercury because it is

about 228 Million km

away from the sun.

Mars

is m

ade

of:

0.13% Oxygen 95.32% carbon dioxide

2.7% nitrogen (is a

chemical element that is

colourless, odourless,

tasteless, and mostly inert

diatomic9having two atoms

per molecule) gas.) 1.6% argon (and inert

gaseous element that

makes up about 1% of

earths atmosphere. 0.08% carbon monoxide

Red orange appearance of

the Martian surface is

caused by iron (lll)oxcide,

more commonly known as

hematite (a black, brown,

or red mineral consisting

of iron oxide) or rust.

Shield volcano, Olympus

Mons, at 27km is the

highest known mountain

in the solar system. It is

also three times taller

than Mt. Everest.

A Martian (Mars) year

is equal to 1.8809 earth years.

Livi

ng o

n

Mars

If you were to live on Mars

you would need a very

large structure or series of

buildings that are very

well insulated from the

surface conditions of Mars.

This structure would have

to have the means of

being self efficient. This

means the ability of growing food by means of

hydroponics (growing

plants in liquid nutrient).

Oxy

gen

If we were to live on Mars

we’d need to be able to

produce oxygen. Large

amounts of elemental

oxygen can be found in

metal-oxides of the surface, and in the soil. A

soil sample taken by the

Phoenix lander (a probe)

indicated the presence of

perchlorate (a salt or ester

of perchloric acid, used in

medicine, fireworks and

rocket fuel).

Food

If we were to live on Mars we’d need

a way to produce food and water.

Mainly vegetables and fruit, which

could be done by hydroponics. Plus

supplemental foods that could be

brought from earth in the form of

RTE packets (ready to eat).

Scientists have been working

towards and researching a way of

terraforming Mars. Terraforming of

mars the hypothetical process by

which the climate, surface, and

known properties of Mars would be

deliberately changed with the goal

of making it habitable by humans

and other terrestrial life.

Moons Mars has two moons:• Phobos- has a

diameter of 22.2 km• Deimos- has a

diameter of 12.6 km

Condit

of

Jupit

er

Jupiter would almost be

impossible to live on due

to it has no surface. Jupiter is made up of gas,

86% Hydrogen (a highly

reactive colourless gas)

and 13% Helium (a non-

flammable inert gaseous

element that is colourless

and odourless. Source:

natural gas. Use: inert

atmospheres, cryogenic

research, lasers, inflating

balloons.)

Weather on Jupiter is

even easier to forecast

than it is on earth. But if you were to go

there on holiday here’s

what to expect: furious

jet streams blowing bands of clouds in opposite directions at

speeds of over 500 kmph.

Condit

er

Lightning is ten times

stronger than it is on

earth. And hail stones

are likely the size of footballs. You will see on

Jupiter a red dot, that is

constantly moving. This

is a hurricane, they like

to call it, that is up to

300 years old. The storm could fit up to 2-3

earths into it.

Tem

pera

tu re

There is no permanent

temperature on Jupiter.

Instead its got layer after

layer of clouds. As you

descend further down into

Jupiter’s clouds it starts to

stink, due to ammonia(a

colourless pungent gas that

is highly soluble in water)

and H2s (Hydrogen Sulfide- a

colourless, toxic and

flammable gas at STP(standard temperature

and pressure) Is also used in

industry and in insecticides)

Tem

pera

tu re

Go even further down and

you’ll hit water. These

clouds are what produce

Jupiter’s ferocious lightning.

Below that it starts to get

hotter and pressure is

heavier. Then the clouds

end, it’d be like looking into

a bottomless pit. Go even

further down and reach a

point where protons (stable

nuclear particle) lose track

of electrons (negatively

charged elementary

particle).

Gra

vit

y

Jupiter has a mass of 318 times

that of Earths, but due to it’s

size, the gravitational

acceleration on its surface is

only about 2.58 times that on

earth. There is more gravity on Jupiter

than there is on Earth.

There is probably no way we

could live on Jupiter, the gravity

there would be too strong and

we’d probably squashed flat as

soon as we step out of the

rocket (or whatever spacecraft

we were to use)

Gro

und

mate

rial

There really isn’t any

surface on Jupiter, because it is a gas planet. Scientists believe that Jupiter was formed by a disc

of gas and dust. Matter fell upon matter, it was believed

to be a game of gravitational survival.

A race that Jupiter ultimately won.

Wate

r

It is almost impossible

to get water on Jupiter, due to everything is just made up of gas and clouds. But you might

somehow be able to

extract water from the

water clouds.

Oxygen

Here again it would be

almost impossible to

get any oxygen on Jupiter. I think the only thing you could

bring is a endless supply of oxygen from

earth.

Food

There would absolutely no place on

Jupiter where you could plant food. Your

only hope for survival

would be in the RTE packets (ready to eat).

Moons

Jupiter has four main moons

• Io- has a diameter of

3,630.6• Europa- has a diameter of

3,121.6• Callisto- has a diameter of

4,820.6• Ganymede- has a diameter

of 5,262.4 Ganymede is

bigger than Mercury. Jupiter has 63 known moons,

but are only 1/3 or less the

size of our own moon.

Oth

er

fact

s about

Jupit

er

Jupiter is the biggest planet in

our solar system. Jupiter is the solar systems

vacuum cleaner. Without Jupiter,

Earth would be hit by a comet

every 50 years or so. Jupiter is so roomy that it could

swallow every planet and moon

in the solar system and still

have room for more. If you were to fly around Jupiter

in a jumbo jet, it would take

three solid weeks and you would

have to refuel 5o times.

Oth

er

fact

about

Jupit

er Scientists wonder if

Jupiter has a solid core. If gravity measurements show

no sign of a solid core,

the Jupiter probably formed early, like the

sun.
