... 13, Moscow, 119899 Russia Received April 10, 2007 Abstract--The hypsometric map and the basin height profiles, for the first time relying upon a spherical daturence surface, have been constructed based on the generalization of the heights measured within the hemisphere including the ring structure of the South Pole-Aitken basin. ... 3 2 Assuming that the initial structure of the SPA basin outer ring is circularly symmetric, we can estimate the general dimensions of this uniquely giant lunar...
... This is a systematic attempt to identify and assess near-equatorial, high-eccentricity orbits best suited for studying the Earth's magnetosphere, in particular its most dynamic part, the plasma sheet of the magnetotail. ... It is therefore quite important to identify orbits which give the best scientific returns. ... A systematic procedure was developed to identify, evaluate and study orbits of scientific satellites that study the Earth's magnetosphere, in particular its plasma sheet and magnetotail...

Archaeoastronomy The Journal of Astronomy in Culture Australian Aboriginal Geomythology: Eyewitness Accounts of Cosmic Impacts? Duane W. Hamacher1 and Ray P. Norris2 Abstract Descriptions of cosmic impacts and meteorite falls are found throughout Australian Aboriginal oral traditions. In some cases, these texts describe the impact event in detail, suggesting that the events were witnessed, sometimes citing the location. We explore whether cosmic impacts and meteorite falls may have been witnessed by
