  1. Deepest depressions would allow some atmospheric pressure, perhaps even a helium ball cap over an O2 atmosphere.

    Qarla, please provide content rather than click bait in the future.

  3. A lot of major problems are being ignored in this Mars colonization fantasy. Outside the Earth’s atmosphere and her electromagnetic field travellers to Mars would be exposed to beta and gamma radiation from the Sun as well as cosmic radiation coming from all directions. A recent study concluded that inside of six months (which is less time than it would take to get there) this radiation exposure would lead to permanent damage to a traveller’s nervous system and dementia which would be not be recoverable. Once on the planet some of the exposure would be ameliorated. The Solar radiation would only come from the sky during the dawn to dusk period and the cosmic rays mostly only from the sky but all day (and night) long. The only way this could even be imagined to work is if the colony was set up on top of a lead mine. We mostly know what the problems would be with growing food and conserving water, but there are some things we don’t know. We know generally what zero gravity does to a person over six months to a year, and it is not good. Mars has gravity, about a third of Earth’s at the surface IIRC but we weren’t evolved for that and we don’t really have a good idea of what what a lifetime of that would do. We have no idea what this would do to developing children and I can imagine the results would somewhere between awful and complete inviability. Add on to all that the cancers that would follow from all the radiation exposure.
    Anyone who thinks our species can avoid extinction by colonizing Mars needs to think again.
