Difficulties and hazards include radiation exposure during a trip to Mars and on its surface, toxic soil, low gravity, the isolation that accompanies Mars' distance from Earth, a lack of water, and cold temperatures.

The notional journeys outlined in the November 2016 talk would require 80 to 150 days of transit time, with an average trip time to Mars of approximately 115 days (for the nine synodic periods occurring between 2020 and 2037).

After about one minute, circulation would stop altogether. After another minute, you'd be dead by asphyxiation. There is some good news to take away from this morbid message. You can likely survive unprotected in space for as long as 90 seconds, which is plenty of time to be rescued!

See NASA's big plans for its new Mars rover, Perseverance (CNN) The NASA Perseverance rover has been confirmed to be healthy and is now on a journey to Mars. It will take between 6.5 and seven months before the rover lands on the red planet in February 2021.

In total, the four rovers that have already gone to Mars are: Sojourner, Spirit and Opportunity, and Curiosity. The Perseverance rover will be heading to the Red Planet soon.

Sometimes it's close to Mars, when it's making a pass, and other times it's far away, at the other side of the track. The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.

Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius). In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C).

Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.

Landing the BFR in the sands of Mars is going to be a very dangerous undertaking. Sand will be blown away by the rocket blast making for a very uneven touchdown and possible tip over. The landing site needs a somewhat even rock base for stability control.

The moon doesn't really have anything to block you from getting zapped (technical term). Really, you would have to definitely live in caves on the moon, but on Mars, it might be possible to live above-ground. You would still get a fair bit of radiation exposure, though.

However, for reasons that are still poorly understood, the Martian atmosphere thinned. The leading theory is that Mars' light gravity, coupled with its lack of global magnetic field, left the atmosphere vulnerable to pressure from the solar wind, the constant stream of particles coming from the sun.
