the mars rover landed in 2012 and is the 3rd rover on mars, even though it wasn’t the the 1st it is the most equip and is the most intelligent one.
there was a time called 7 mins of danger where the had to stop 20,000 km to 0 km in 7 mins. NASA said it was the most stressful time.
they said that on mars there were sighs of a lake or some type of pond that would have contained water. now they are hoping that maybe even meters below the ground there might be sighs of life.
i understand that if anything was to go wrong they would have lost 2 and a half billion dollars and years of preparation for nothing, and that it took years and years to build.
why has the water dispersed if earth is closer to the sun?
