On Mars we have minerals and non-ore rocks. *We have yet to find an tradiRonal “ore” deposit on Mars. • The melRng point of aluminum oxide, over 2000oC requires lots of energy to melt the source material so that ions (Al3+ and O2–) are free to move to the electrodes for the electrolysis to work. On Earth, this process is ~6x more costly than the producRon Fe (reducing method: ore, coke and limestone). • Other melRng points: • Iron (sulfide or oxide) ore: 1800 °C • Glass: 1400 °C to 1600 °C • Mafic minerals (e.g., pyroxene) 1000 to 1200 °C 43.2°N 164.2°E • Phyllosilicates: > 1000 °C 39N, 172Ec 20 Resource ROI 2 1st EZ Workshop for Human Missions to Mars Sheet Silicate / • Elevated levels through center of EZ High-Si Glass • Evidence of mineral alteraon and precipitaon hydrated silicates TES over THEMIS 39N, 172Ec 21 Resource ROI 3 1st EZ Workshop for Human Missions to Mars Arcadia ferric oxide nanoparRcles/dust abundance (blue low, red high) Planta • Elevated levels through center of EZ Planes Materials • TES abundances as high as 0.2 (red) or ~10x low abundance areas (blue) • Evidence of mineral alteraon and precipitaon • Ubiquitous, low slope, medium and fine grained surface deposits –> enhancing mining, manufacturing, OMEGA 3D construcRon and traverse operaons over MOLA Shaded • PotenRal for lave tube and tunnels Relief • MulRple elevated mineral assemblages across region 39N, 172Ec 22 RROI3 PotenRal Resource ROIs TES Abundances 1st EZ Workshop for Human Missions to Mars 2− This EZ contains moderately low to elevated Sulfate SO₄ abundances for a variety of minerals and rock types (detecRon limits need to be enhanced).

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

The valley is about 2.5 km wide; the scene covers 9.8 km by 27.9 km centred on 5.1°N/48.26°W. The valley floor at top right exhibits a 200 m-wide channel covered by dunes and debris. This channel suggests that the valley might have been carved by water flowing through the system over a long period, in a manner similar to rivers on Earth.

It allows to compute (polar- ized) radiances, irradiances, and actinic fluxes in the so- Radiative transfer modeling is essential for remote sensing lar and thermal spectral regions. libRadtran has been used of planetary atmospheres, but also for many other fields in 5 for various applications, including remote sensing of clouds, atmospheric physics: e.g., atmospheric chemistry which is aerosols and trace gases in the Earth’s atmosphere, climate largely influenced by photochemical reactions, calculation of studies, e.g., for the calculation of radiative forcing due to 30 radiative forcing in climate models, and radiatively driven different atmospheric components, for UV-forcasting, the dynamics in numerical weather prediction models.
