2:26 The other day i have read that scientists are actually planning to melt the ice on mars by using giant mirrors reflecting the light of the sun and pointing it directly at the polar ice caps. Once they manage to melt enough ice, carbon dioxide gas from the ice caps would evaporate and become part of the atmosphere. Water would flow on Mars and due to CO2 in its atmosphere; the planet can heat up over time (greenhouse effect) allowing water to continually sustain on Mars. (read on below)

Once there is water on mars, water will evaporate into the atmosphere and condense, creating clouds, rain and snow. Thanks to water and warmth on mars, plants can be planted on mars and once plants begin to grow on mars, theyll give off oxygen in a process called Photosynthesis And the ozone layer formed from oxygen that protects us from the suns deadly UV radiation will begin taking shape. But the whole process would take a veereey long time!

Quite possibly in Europa in the ocean underneath the ice? Pretty cool thought to be honest.

It is very interesting to think under those miles and miles of ice could be an ocean of water that harbors life.

Yes. Very interesting AND very humbling. To finally know that we are not alone in the universe, is quite humbling.
