1. Mars does not have oxygen and sunlight therefore, Mars is very cold. The average temperature on Mars is minus 80 degrees Fahrenheit. Not to mention, its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it.

2.  The precise duration of each journey depends on when it is taken,since both Mars and Earth's orbits are not perfectly circular, the time it takes to travel between them varies from six to eight months.

3. Mars is an ideal place to search for the residues of microbial life, test new technologies, and lay the groundwork for human exploration down the road. The mission plans to investigate whether microbial life existed on Mars billions of years ago and therefore that life is not unique to Planet Earth. The hypothetical colonization of Mars has received interest from public space agencies and private corporations. I think that a private corporation SpaceX which was founded by Elon Musk will be the first colonists on Mars because Elon Musk is already developing a vehicle which could be a game-changer for space travel. Starship, as it's known, will be a fully reusable transport system capable of carrying up to 100 people to the Red Planet.
