Life on Mars? Watch
Calling all science nerds and future astronomers! I have a question to pose to you all:
What could have caused the atmosphere on Mars to be what it is today? Also, where do you think the water has all gone?
Solar winds stripping the atmosphere away since the magnetic field is weak compared to Earth's. With the water its probably frozen in the ground and some vapour in the atmosphere may have also been taken away by the solar winds.
