SOLAR SYSTEM

Detailed explanation-1: -The confirmation that liquid water once flowed on Mars, the existence of nutrients, and the previous discovery of a past magnetic field that protected the planet from cosmic and solar radiation, together strongly suggest that Mars could have had the environmental factors to support life.

Detailed explanation-2: -Mars has evidence of being warmer in the past and of having stable liquid surface water for potentially hundreds of thousands of years. So, it’s possible that in Mars’ past there was a time where life could have evolved in that particular environment.

Detailed explanation-3: -Mars was a water world. Planetary scientists see evidence of water all over the red planet, but a new study of meteorites suggests that Mars was once a blue planet, like Earth, covered in water as deep as 1, 000 feet/300m.

Detailed explanation-4: -Understand, first, that scientists do not actually believe any life-even the microscopic kind-could possibly exist on either of Mars’ moons. Phobos, the closer of the two moons, is home to an atmosphere void of virtually any life-supporting systems that would make life on the lunar body nearly impossible.

Detailed explanation-5: -At this time, Mars’ surface cannot support life as we know it. Current missions are determining Mars’ past and future potential for life.

Detailed explanation-6: -The atmosphere of Mars is mostly carbon dioxide, the surface of the planet is too cold to sustain human life, and the planet’s gravity is a mere 38% of Earth’s.
