Home ›This is an activity about how much atmospheric pressure is needed on Mars to maintain surface water and why the planet does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.
