You will die instantly because:
The pressure on Mars is so low that exposure to the atmosphere would kill you. Little bubbles of gas in your blood would go out of solution, cause air embolisms, severe decompression sickness and bloodvessels would pop everywhere in your body.
Disregarding that CO2 is poisonus to humans if the concentration is greater than 3%. 10% oxygen would leave 85% CO2 (if the oxygen is extracted from the atmospheric CO2). So it would be poisonus to breath.
the human will die beacause there is no air on mars
As of now, there are no people living on Mars. There are plans for manned missions to Mars in the future, but it is not predicted to happen within the next 100 years. Extensive research and technological advancements would be needed to sustain human life on Mars for long periods of time.
To see a crescent on a planet, most of the surface that is facing you must be dark. For this to happen the planet must be between the sun and you. Planets that are further away from the sun therefore will never have a crescent phase when viewed from Mars.
A parachute would open ABOVE Mars, just as it would above our planet
There would be no flame because fire needs oxygen to burn, and the Martian atmosphere consists mainly of Carbon Dioxide.
If you are not wearing a suit you could die
First we would have to actually make a successful trip to Mars...
The stomach would fill with air and cause the child to vomit.

Mars is the only one, but no-one has gone there yet. It is very cold and the atmosphere can't be breathed.

No. Plans are being discussed for a mission to mars, but if it does happen, but none would happen until at least 2018.
Thay would die a very painful death
He/she would suffocate and/or freeze.
If it did, it would be destroyed. Due to gravity, it would not happen.
