  2. Terraforming - Wikipedia

    en.wikipedia.org/wiki/Terraforming

    An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.

    Iron aerosol in the atmosphere will also be required for the reaction to work, and iron can come from Mercury, asteroids, or the Moon. (Loss of hydrogen due to the solar wind is unlikely to be significant on the timescale of terraforming.) Due to the planet's relatively flat surface, this water would cover about 80% of the surface, compared to ...

    Opportunity found small structures, named "blueberries" which were found to be rich in hematite, a major ore of iron. [49] These blueberries could easily be gathered up and reduced to metallic iron that could be used to make steel. "Blueberries" (hematite spheres) on a rocky outcrop at Eagle Crater. Note the merged triplet in the upper left.

    The above classification scheme is the most commonly used and accepted, though sometimes an older system is used which divides iron-rich sedimentary rocks into three categories: bog iron deposits, ironstones, and iron formations. A bog-iron deposit is iron that formed in a bog or swamp through the process of oxidation.

    Widmanstätten pattern in an iron-rich meteorite An example of a primitive rock is the achondritic iron-nickel octahedrite mineral seen in the Widmanstätten pattern that is found in a number of iron-rich meteorites .

    Three methods of global warming are described in the work and, Zubrin suggests, are probably best deployed in tandem: orbital mirrors to heat the surface; factories on the surface to pump halocarbons such as perfluromethane into the atmosphere; and the seeding of bacteria which can metabolize water, nitrogen and carbon to produce ammonia and ...

  9. Ironstone - Wikipedia

    en.wikipedia.org/wiki/Ironstone

    Ironstone (sandstone with iron oxides) from the Mississippian Breathitt Formation, Mile Marker 166, I-64, Kentucky. Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially.
