Full Answer

NASA and other agencies have been trying to figure out how to put humans on Mars for many years. The planet has no breathable air, so anyone who tries surviving on the Red Planet must take oxygen with them. The soil will not support crops, and there is no water.

In order for humans to survive on Mars, at least in the beginning, necessities must be delivered from Earth. Scientists have thought of creating an air-tight habitat that would allow settlers of the planet to grow their own food and to live in a breathable environment. A water recycling program must be implemented, as would some type of radiation protection.

The temperatures on Mars will also make it difficult for humans to live there. Although high temperatures can reach a comfortable 70 degrees Fahrenheit, low temperatures can plummet to a bone-chilling -225 F. The planet has a thin atmosphere that does little to protect it from meteors and comets, making it a dangerous place for humans.

    If you weighed 50kg on Earth, how much would you weigh on Mars?

    A:

    A person weighing 50kg (110lbs) on Earth would weigh 19kg (42 lbs) on Mars. This is because the gravitational force on Mars is only 38 percent that of the gravitational force on Earth.

  • Q:

    How would a human being fare on Mars?

    A:

    Low pressures, a lack of oxygen and cold weather on Mars would force humans to remain confined to spacecrafts and vehicles, according to physics.org. Astronauts could occasionally walk around in the open, but only if they wore spacesuits. Settlers would risk dying if their spacesuits became seriously damage. Underground shelter would be an ideal scenario. As of 2014, no settlement on Mars has been established.

    How many light years away is Mars?

    A:

    Mars is considerably less than 1 light-year away from Earth. According to Cornell University, Mars orbits the Sun at an average distance of 1.5 times the Earth's mean orbital distance. At the two planets' closest approach, the distance between them shrinks to 0.5 astral units, which equals 75 million kilometers.
