I understand the curiosity and the “need” to discover, but my inference was purely logistical.
Right now, with our current technology, the only viable solution would have to be robotics.
Mars seems to be about the limit of endurance for human travel.
"Right now, with our current technology..." the US couldn't put a man on the moon, yet we once did. Technology changes. Musk and others are driving those changes, since NASA has been emasculated and eviscerated.
"Mars seems to be about the limit of endurance for human travl."
Based on what?? The limit of endurance depends on the conditions of the system used, and neither you nor I know what that will be. All the technology discussed by Arthur C. Clarke in 2001 is realizable with today's technology base.
