Space agencies have discovered that Mars was once covered by an ocean. This is news that was much speculated upon and had a high degree of probability. But now it has been confirmed.
This is great news as it really makes two important things closer to becoming a reality:
1. The discovery of extraterrestrial life - as it is now confirmed, Mars had an ocean a long, long time ago. While we still do not have proof that life of any kind existed there, the general rule is: where there is water, there is life. So, now with both the moon and Mars having been confirmed as having water (the moon even today, Mars in the past) and perhaps Europa of Jupiter and Enceladus of Saturn as well, we have found that water may not be as rare a commodity in the universe as we once thought. This discovery alone, highly increases the probability of life outside of Earth. Perhaps it is now just a matter of time before we have hardcore evidence.
2. Since there are more places where water is or was, it also increases our chances of being able to colonize these worlds in the future. Colonization is an absolute must for the longevity of the human race.
Let's see where we find water next.
