“The more we observe Mars, the more information we’re getting that it really is a fascinating planet, from the Curiosity Rover we now know that Mars once was like a planet very much like Earth, with long salty seas, with fresh water lakes, probably with snow capped peaks and clouds and a water cycle just like we’re studying here on Earth… Something has happened to Mars, it lost its water.”
The quote above comes from John Grunsfeld, a five-time space flow astronaut and associate administrator of NASA’s Science Mission Directive.
It was given at a NASA press conference where representatives told the world that there is water on Mars, that it’s not the dry, arid planet we imagined it to be, and that it was once very much Earth-like and still holds the possibility of harbouring life. After all, water means life.
While this announcement came as something of a shock to the public, scientists have been telling the world for some time now that Mars was once very much Earth-like, that it probably hosted some form of life, and that something happened in Mars’ past which completely changed its planetary/atmospheric conditions.
