What they found is evidence that there was liquid water in this crater
on Mars.

Ergo...
1) Mars was warmer in the past.
2) There was rain on Mars.

Earth was once a frozen rock, like Mars is now. The key is to get
enough water vapor in the atmosphere to get the greenhouse effect
going. (CO2 isn't doing it, folks...)

This indicates that Mars can be terraformed.

If mar's core is dead (cooled and solid) there can be no magnetic field
to protect the atmosphere from solar winds and blasts. If it had a
molten liquid metal core in the past it could have very likely had a
protected atmosphere. It can never be terriformed because there is no
magnetic field or not enough to protect it. Dead is dead. When the
earth's core solidifies, that will be the end of it. The sun will blow
away the atmosphere in short time and all the water will evaporate into
space.


If it blows away in a million years, we'll make another atmosphere then.
