John Batchelor and I welcomed back Dr. Haym Benaroya to discuss Mars habitats and the use of Martian insitu resources. We talked about Mars methane, nitrogen in the Martian soil, water on Mars, the use of lava tubes, Mars gravity, engineering Martian structures and more. John asked Dr. Benaroya for a timeline for going to and living on Mars. He suggested around the time range of 2075. He also said robots would go there first and pave the way for humans.
