  Colonization of Mercury - Wikipedia, the free encyclopedia
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.
Because of this similarity any colonization of Mercury might be performed with the same general technology, approach and equipment as a colonization of the Moon.
Mercury is also deep in the Sun's gravitational potential well, requiring a larger velocity change (delta V) to travel to and from Mercury than is needed for other planets although, in the past, Gravity assist orbits using Venus have been used to reach Mercury.

 Mercury (planet) - Wikipedia, the free encyclopedia
Mercury ranges from −0.4 to 5.5 in apparent magnitude, and its greatest angular separation from the Sun (greatest elongation) is only 28.3°, meaning it is only seen in twilight.
Physically, Mercury is similar in appearance to the Moon as it is heavily cratered.
One theory is that Mercury originally had a metal-silicate ratio similar to common chondrite meteors and a mass approximately 2.25 times its current mass, but that early in the solar system's history Mercury was struck by a planetesimal of approximately 1/6 that mass.

Mercury ranges from andamp;amp;minus;0.4 to 5.5 in apparent magnitude; Mercury is sufficiently "close" to the Sun that telescopes rarely examine it (the greatest elongation is 28.3°).
The atoms that compose Mercury's atmosphere are continually being lost to space, with the average "lifespan" of a potassium or sodium atom being approximately 3 hours (during the Mercurian dayandamp;amp;mdash;and only half that at perihelion).

Mercury was called Mercury when in the evening sky, but was known as Apollo—in honor of the Roman god of the Sun when it appeared in the morning.
The atoms that compose Mercury's atmosphere are continually being lost to space, with the average "lifespan" of a potassium or sodium atom being approximately ~3 hours (during the Mercurian day—and only half that at perihelion).

Mercury ranges from -0.4 to 5.5 in apparent magnitude, and its greatest angular separation from the Sun (greatest elongation) is only 28.3°, meaning it is only ever seen in twilight.
It is thought that early in Mercury's history, a giant impact with a body several hundred kilometres across stripped the planet of much of its original mantle material, resulting in the relatively thin mantle compared to the sizable core [2].
Diagram showing Mercury's large coreIt was formerly thought that Mercury was tidally locked with the Sun, rotating once for each orbit and keeping the same face directed towards the Sun at all times, in the same way that the same side of the Moon always faces the Earth.

Surface temperatures on Mercury range from about 90-700 K, with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.
The sunlight on Mercury's surface is 6.5 times as intense as it is on Earth, with the solar constant having a value of 9.13 kW/m².
But as the protosun contracted, temperatures near Mercury could have been between 2500–3500 K; and possibly even as high as 10000 K. Much of Mercury's surface rock would have vaporized at such temperatures, forming an atmosphere of "rock vapor" which would have been carried away by the solar wind.

Mercury ranges from -0.4 to 5.5 in apparent magnitude; Mercury is sufficiently "close" to the Sun that telescopes rarely examine it (the greatest elongation is 28.3°).
The half-moon phase occurs at greatest elongation, when Mercury rises earliest before the Sun when at greatest elongation west, and setting latest after the Sun when at greatest elongation east (its separation from the Sun ranging from 18.5° if it is at perihelion at the time of the greatest elongation to 28.3° if at aphelion).
The only spacecraft to approach Mercury has been the NASA Mariner 10 mission (1974–75).A second NASA mission to Mercury, named MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), was launched on August 3, 2004 from the Cape Canaveral Air Force Station in Florida, USA, aboard a Boeing Delta 2 rocket.

Colonization of those bodies is in fact much less desirable than orbital colonization, even though Mars and the Moon are the only practical solid bodies suitable for colonization in the solar system, at least for the next few centuries.
Mercury is too hot during the day and too cold at night, as the days and nights are so long.
Colonizing the Moon with nuclear fuel shipped from Earth will also be expensive, and we can probably rule it out as a practical approach to generating large amounts of power.

 Mercury Removal, Methylmercury Formation, and Sulfate-Reducing Bacteria Profiles in Wetland Mesocosms Containing ...
An obvious concern in using constructed wetlands to remove mercury is the potential formation of methylmercury (CH Hg) since wetlands are known contributors of CH Hg to downstream lakes and waters (St Louis et al., 1994; Hurley et al., 1995; Branfireum et al., 1998; 1999).
Surface water total mercury and methylmercury samples were collected from each tank at the point of discharge for a period of six months beginning in May 1999.
Although mercury methylation rates (MMR) were not established in these systems, it is interesting to note that the flux of methylmercury from tank 1 (large abundance of Desulfobacter sp.) increased in the month of August compared to no observable increase in tank 2 (Figure 2).
