Does the NASA have plans to generate an atmosphere for life in Mars?
NASA does not have plans to generate an atmosphere on Mars. We are, however, trying to better understand the natural atmosphere currently at Mars. If humans do get the opportunity to go to Mars in the future, they will indeed need to wear spacesuits with Oxygen tanks in order to breathe because the Martian atmosphere consists of mainly carbon dioxide (95.3%) which is not life-sustaining for humans.
