Show transcribed image text Homework 1 Exploration Problem Kieserite as a Mars Colonization Resource Material Introduction One aspect of colonizing Mars is identifying and utilizing resources that are available there (in-situ). A promising first colony location is Chandor Chasm, which is a canyon that extends northward of the equatorial Valles Marineris. It has several desirable attributes: 1) it is near the equator, which reduces the energy (fuel) needed to slow incoming vehicles, 2) it is at a low elevation, so the atmospheric density and height are greater than higher elevations again reducing the energy needed to slow incoming vehicles. 3) it is in a canyon, the sides of which provide shielding from galactic cosmic radiation from all directions except directly overhead, and 4) is has large surface beds of the mineral kieserite, which can be processed for water (and hence oxygen), and magnesium metal for structural usage, and its constituent components can be used to make cement. Assignment Determine the energy needed to break kieserite down as follows, showing your calculations and information sources a) How much energy is needed to break the hydrate off (in kJ per kg)? . MgSO4 H2O MgSO4 H20 b) How much energy is needed to break the sulphate off (in kJ per kg)? MgSO4-MgO+ so, . c) How much energy is needed to reduce the magnesium oxide to metal (in kJ per kg)? d) A type of Sorel cement, Magnesium oxysulfates (MOS), are formulated by the reaction between magnesium oxide and magnesium sulfate solution. Do you think it would be feasible to manufacture this cement from the above breakdown products of kieserite? How would you go about doing that?
