MARC recordExospheric transport restrictions on water ice in lunar polar traps / R. Richard Hodges, Jr.
| Title: | Exospheric transport restrictions on water ice in lunar polar traps / R. Richard Hodges, Jr. |
| Author(s): | Hodges, R. Richard, |
| Date: | 1991. |
| In: | Geophysical Research Letters. (1991.), Vol. 18(11) (1991) |
| Abstract: | At least 10¹⁷ g water has accreted on Moon by reduction of ferric iron by solar wind protons, vapourization of chondrites, and comet impacts. Most is probably there now. If water were to have migrated to permanently shaded cold traps near lunar poles, ice deposits with densities >1000 g cm⁻² would cover traps, providing accessible resources. However, exospheric transport considerations suggest that actual amount of water ice in cold traps is probably too small to be of practical interest. Alternative is global assimilation of most of water into regolith, which must account for about 30 μmol water per gram of soil. |
