How would I do Mars? I'd start by setting up a support system for humans. We've done a lot. We need to do more surveying and to put into place an infrastructure for communications and information.
Step One
Need to pre-position:
- GPS, Weather, Ground imaging and communications satellites. Put 8 in Polar orbit and 8 in Mars-Synchroneous equitorial orbit; minimum. That would cover the entire surface.
- Also satellites have to be in orbit that image our Sun and with Earth. These can be part of the ground imaging satellites.
- We need supplies in orbit. Including vessels for emergency return to Earth. The first landers sent to Mars should be empty and sit in orbit.
- We need to pre-position enough equipment, gear, vehicles and supplies so that they will already be there when humans arrive.
- Continue exploration
- Drones to explore and hunt for lava tubes, resources, and map out landing sites and mineral resources.
- Including flying explorers, tunnel exploring unmanned vehicles, etc...
First Milestone
No humans until shelter, water supplies and minerals are mapped out.
Step Two
- Pre-Position habitat, energy production, and similar resources near the best located site for a human settlement. A mix of equipment in kit format that can be assembled by humans and equipment assembled by robots.
- Send Robots to assemble what is needed
- Assemble, power, energy, water, fuel storage and generation abilities.
- Stockpile backup parts and backups to the backups.
- Continue exploration, including new drones.
- Run power, communications between the assets
- Prepare a landing site.
- Lay guidance and communications assets at each site.
- If tunnels available, put assets in the tunnels. Bury what can be buried.
Including solar panels, cleaning robots, fuel cells, wind mills and the like.
Second Milestone
Go/No go based on whether enough supplies are pre-positioned for Marsnauts to use and live on.
Now you can send humans.
