'''Mercury''' has been suggested as one possible target for space colonization of the inner solar system, along with Mars, Venus, the Moon and the asteroid belt. Permanent colonies would almost certainly be restricted to the polar regions due to the extreme daytime temperatures elsewhere on the planet unless a shade or lens system was installed. Excursions to the other parts of the planet would be feasible with appropriate measures, particularly along the very slowly moving terminator, which would approximate polar conditions.

It would be possible to shelter habitats underground or have mobile habitats that constantly follow the terminator (border between day and night) perhaps on a road or rail system. Mercury has very long days and nights and the planet is small, so the velocities of the mobile habitats would be realistic at about 3 meters per second at the equator reducing in velocity towards the poles. However there could be stop over areas where the mobile habitates go into a tunnel complex to shelter from the intense heat over the long day, these tunnels could also have thin reflective foil simply laid on the surface to act as insulation against the sun's heat reducing the depth needed to go underground. Although the solar flux is high due to the closeness to the sun a large thin transparent lens could be setup over time at the sun facing lagrange point. The lens would allow light to be concentrated at the surface anywhere on the sun facing side if needed and lower the amount of light over the rest of the surface to earth like light conditions if concentrated at say the equator. The use of a transparent lens allows light to pass through without affecting the position of the lens greatly as it would on a purely reflective mirror design, stabilisation of the lens could be via the natural pull towards the sun and a laser system on the planets surface. The concentration of light at the surface allows enomous amounts of power to be concentrated in a small area where solarcells could harvest the energy or allow the smelting of materials for habitates and perhaps a road system. For example a 50 km diameter lens could concentrate over 10 Terra Watts of power to the surface which is around what our earth civilisation uses currently. The energy could also be used for the setting up of a very large magnetic field to protect the surface from the solar wind and harvest large amounts of solar hydrogen for water production, helium 3 could also be harvested for energy or exported around the solar system. If a magnetic field as large as Jupiters pole on is created on Mercury then staggering amounts of hydrogen could be collected in the millions of tons. The energy could also be used to power very large phased array lasers or particle accelerators to move material and spacecraft's around the solar system and even for interstellar missions. Phased array lasers could be used to launch and brake incoming spacecraft negating the need for chemical thrusters as well. There is also sufficient energy that lands on the planet to produce an oxygen atmosphere in a relatively short time scale from the surface rocks but it would start to affect the advantages of having no atmosphere. Perhaps smelting of the entire surface into domes with the lens system so when oxygen is introduced it will not recombine with the surface material again allowing people to move freely about without a suit except at night. There is also the possibility of having a large ring mirror near the lagrange point on the other side of mercury to shine light back on the darkside of the planet perventing too much cooling, it will require the balancing of the solar light and gravitational forces though. Perhaps we could have a thick honeycomb structure manufactured on the surface which we will fill with regolith which is then smelted with the lens system the molten material will then solidify to form an thick cover which we could live under.
