Meetings at The Jet Propulsion Lab last week indicate that a major reason why NASA is pursuing landing on Mars is to protect human existence from disaster that could arise an asteroid collision in the future or any other calamity that might jeopardize human existence on Earth!
-Was Mars home to microbial life? Is it today?
-Could it be a safe home for humans one day?
-What can it teach us about life elsewhere in the cosmos or how life began on Earth?
-What can it teach us about Earth’s past, present, and future?
