Why? You’re not going to be spending most of your time out on suits anyway. Put some sandbags on the roof.

- jacobush 7y agoBecause the atmosphere will be stripped away by the Sun. But see comment about generating a magnetic field.
- wongarsu 7y agoYes, over billions of years the atmosphere will be stripped away. But the process is way too slow for us to worry about.

NASA estimates, given Mars was given a magnetic field, it would only take a century (give or take) to start to melt oceans. So your estimate seems to be off by a bit.

- jacobush 7y agoNo - it means that the solar wind is affecting the atmosphere enough that a greenhouse effect on Mars is not getting started, even though it could if there was a magnetic field on the planet. This means the solar wind effect is not negligible. An artificial magnetic field plus other means could have a drastic and extremely rapid (in geologic terms, hundreds of years) effect on Mars climate.
