The energy for the trip, the return trip, the duration, and weight requirements associated with radiation shield are why I'm skeptical. It's technically possibly, certainly. So is switching to a 100% solar fueled grid. But I hate to be to pessimistic: I'm older than average here, and I would feel unbelievably privileged to witness humans landing on Mars. I hope it happens.
- lettergram 9y agoIdk how old you are, but I suspect within the next 20-30 years we will be deploying robots that turn the iron, soil, etc. On Mars into a plastic, resin, metal-frameworks, fuel and water. From there robots can build some facilities or at least materials and humans can land in a pre-constructed environment. I dont know about a return trip though, but I do think long term inhabitation is possible. Especially, with our advances in robotics, genetics, and medicine. Also remember it takes a lot less to launch a rocket off of Mars. For instance, you only need 33 tons of propellant to get an 18 ton MAV off the ground[1] [1] http://news.nationalgeographic.com/2015/10/151002-mars-mission-nasa-return-space/ http://news.nationalgeographic.com/2015/10/151002-mars-missi...
