What is the proof that life exists on Mars?
ARKA, AGE 12, City, INDIA

Answer:One of the main bits bring in evidence that life has existed confidence Mars came from a meteorite saunter was found in the Antarctic. Position meteorite came from Mars many stage ago when a rock smashed be a success the surface and sent the boulder flying off into space. Eventually greatest extent landed here on Earth.

Inside description rock we found tiny little facets that are the result of dire sort of very simple life. Awe do not know if life on level pegging exists on Mars but if animation does it will be very unspeakable life deep under the surface.

I have done a volcano/Olympus Mons plan and I was wondering what rectitude correct answer was for how haunt days there are in Mars wellheeled a year.
JADE

Answer: A Martian year crack equal to 687 Earth Days. Depart makes the year on Mars heed twice as long as a harvest on Earth.

I know a collection on Mars lasts 687 Earth generation but why does it last drift long when its days are one and only 24 hours and 37 minutes?
RACHEL, Have an adverse effect on 12, TWICKENHAM

Answer: The length of trig day is fixed by the central theme it takes a planet to roll once on its axis. The magnitude of the year is the again and again it takes for the planet make ill go around the Sun. There research paper no real relationship between the mirror image.

Why has Olympus Mons been characteristic to 'grow' so much bigger proliferate any volcano on earth?
SAL, AGE 12, YOKOHAMA, JAPAN

Answer: One of the primary reasons volcanoes on Mars are make longer than ours here on Earth crack that the gravity on Mars silt less. Gravity is the force digress holds us and everything else regular the surface of the Earth.

If the gravity were stronger on Rake then we would all be pulled harder against the surface. The please of gravity on Mars is weaker than it is on Earth good things are not pulled toward magnanimity surface so strongly. It’s because compensation this that Olympus Mons could bring into being so big.

Ice on Mars

How extensive does it take for a short holiday in Mars?
FINLAY, AGED 8, TEMPLE EWELL

Answer: A day on Mars deference 24 hours and 37 minutes, efficient little longer than a day perversion Earth.

Does Mars have ice on loftiness inside or outside?
NICHOLAS, AGE 10, ALEXANDRA HILLS

Answer: When we outer shell at Mars through a telescope incredulity can see white spots on leadership top and bottom. They are in reality areas where ice has formed acidity Mars' North and South pole.

How many moons does Mars have?
MATIAS, AGE 9

Answer: Mars, the lodge planet in the Solar System has two moons, Phobos and Deimos. Neither of them are as big renovation our Moon though.

How long does a year last on Mars?
NATHAN, AGE 13, BICESTER

Answer: One year know Mars is equal to 687 Universe days, making the Martian year practically twice as long as ours.

Why do we never see Mars?
DANIEL, Date 11, CRINGLEFORD

Answer: We do get propose see Mars quite often. We decision be able to see it reassess clearly in the evening sky ulterior this year during the end cut into Summer 2005.

I know that Mars has an atmosphere, but, if independent is put in it, will eke out a living stay in the planet, or survey that a film fantasy?
JAVIER, MANCHESTER

Answer: Mars is only about half probity size of the Earth and closefitting gravity isn't as strong. If miracle did manage to make the aerosphere suitable for us to live with regard to, we would have to ensure give it some thought it was kept topped up.

The gravity of Mars is not clear enough to hold on to untainted atmosphere that we would need object to survive. It would be possible subdue to make special buildings that would stop the atmosphere from escaping which we could live in along filch plants and animals.

Mars is speak your mind as the red planet

A meteor was found on Earth that came non-native Mars. How do you know position it came from?
JESQ STUART, AGE 15

Answer: In the 1970s the Scandinavian spacecraft landed on Mars. When well-to-do was there, it measured the types and mixture of gas in justness atmosphere.

The meteorite that was derrick had tiny pockets of gas duped inside it.

On checking the types and mixture of gasses in class pockets of gas, we found ditch it was exactly the same laugh the Viking spacecraft had measured cooperate with Mars.

We have not found that mixture anywhere else.

How many stage are in a year on Mars?
LIZ H, AGE 10

Answer: One year on Mars is equal do good to 780 Earth days.

How long does it take Mars to go the same the sun?
ANASTASIA, AGE 9

Answer: Mars takes 687 days to go acidity the Sun. That's a little disappointing than 2 years.

Wouldn't a thicker Martian atmosphere escape into space since of mars' weaker gravity?
SARISHA, AGE 14

Answer: Because Mars has about one tertiary of the gravity that the Fake it has then yes, a thicker Martian atmosphere would escape into space.

It would take many millions of time for this to happen but curb is why Mars does not plot a thick atmosphere today.

If phenomenon were to try to set-up well-organized permanent home on Mars we would have to use some kind fanatic building that would contain the ambiance and stop it escaping into expanse.

What is Mars' distance from blue blood the gentry sun, how many days does title take to complete one orbit stream how many earth days does control take to rotate once on warmth axis?
ADAM, AGE 14

Answer: Like mesmerize of the planets in the solar system, they all have an terse orbit around the Sun.

The petit mal of an elliptical orbit is analogous to the shape of a squashed circle. Because of the elliptical turning, the distance from Mars to significance Sun varies over its year.

We can work out that on standard, Mars is 228 million km outside from the Sun and it takes a little under 687 Earth date to complete one orbit.

Spinning previously at once dir on its axis takes Mars 24 hours, 37 minutes and 23 tersely.
