Hi Kevin, this is super exciting news indeed. To find a large body of underground water raises the possibility of life forms that can survive in those conditions.
I can see that we will be going to Mars in the near future. We just need a faster transit system and better radiation shielding.
A 3 year round trip is probably to long for most people?
You're right, this is some great news. Finding liquid water increases the chances of extraterrestrial life tremendously.
A journey of 3 years is still too long in dangerous space. The time needs to be decreased dramatically, to reduce the hazards.
