I wonder when Mars may have "lost" it's water. Textbooks, fifth grade teachers, and even a recent Economist talk about the hydrological cycle of water - and particularly evapotranspiration - but never, ever about how water is naturally created nor where it comes from. Thank you, Internet, for informing me that it mostly comes from outer space. Questions: Were Mars and Earth created around the same time frame; if so, did they collect roughly the same amount of water from space during early formation (granted Mars being smaller/less dense); assuming Mars had surface water at some point, did it's water seep underground or was it exhausted into space? Or both. What "event" would cause Mars to loose its water? If that "event" was the loss of a dense or heavy enough atmosphere, what caused that loss? Is it possible that Mars' water siphoned off over to Earth (getting back to the timeline question above)? Just a few questions that never seem to get answered by teachers, textbooks, or nasa ...
