We have assumed that they are easily available.\r\n\r\nIf ice turns out to be very hard to find locally, it would make sense to look into defining a model of extracting subterranean water for use.\r\n\r\nFeel free to share your idea of how we should integrate into mars-sim when it comes to water modeling, in conjunction with what you have read from good literature out there."},"comment":{"url":"https://api.github.com/repos/mars-sim/mars-sim/issues/comments/442543170","html_url":"https://github.com/mars-sim/mars-sim/issues/154#issuecomment-442543170","issue_url":"https://api.github.com/repos/mars-sim/mars-sim/issues/154","id":442543170,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0MjU0MzE3MA==","user":{"login":"mokun","id":1168584,"node_id":"MDQ6VXNlcjExNjg1ODQ=","avatar_url":"https://avatars0.githubusercontent.com/u/1168584?v=4","gravatar_id":"","url":"https://api.github.com/users/mokun","html_url":"https://github.com/mokun","followers_url":"https://api.github.com/users/mokun/followers","following_url":"https://api.github.com/users/mokun/following{/other_user}","gists_url":"https://api.github.com/users/mokun/gists{/gist_id}","starred_url":"https://api.github.com/users/mokun/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mokun/subscriptions","organizations_url":"https://api.github.com/users/mokun/orgs","repos_url":"https://api.github.com/users/mokun/repos","events_url":"https://api.github.com/users/mokun/events{/privacy}","received_events_url":"https://api.github.com/users/mokun/received_events","type":"User","site_admin":false},"created_at":"2018-11-28T17:55:58Z","updated_at":"2018-11-28T17:55:58Z","author_association":"MEMBER","body":"But at 30 E 0 N, we do have some signature of H2O"}}
