These water maps and their ancillary data were prepared for studying the effects of Earth's magnetotail on the formation of the lunar surface water by Dr. Shuai Li at University of Hawaii. It is…

This map is one in a series of 1:500,000-scale geologic maps initiated by the National Aeronautics and Space Administration to investigate areas of particular scientific interest on…

The north Kasei Valles area merits detailed geologic study because it contains part of a large channel system whose age can be determined relative to geologic units that range in…

Many indicators for ocean on Mars were proposed: outflow channels and features related to the evolution of standing bodies of water (polygons, lobate impact craters), features consistent with the…

After the initial proposal of Contact 1 and 2, previously published papers about ocean on Mars can basically be divided in two groups. The first one was based on shorelines theory, however,…

The 1960s Apollo Lunar Module could support two men for three days, and the Apollo space suits carried only enough oxygen and cooling water for eight hours of work on the moon. Because of these…

The Microscopic Imagers (MI) on the Mars Exploration Rovers, Spirit and Opportunity, have returned images of Mars with higher resolution than any previous camera system, allowing detailed…

Sub-glacially erupted volcanoes form free-standing flat-topped mesas, known as tuyas. Although there are some silicic edifices (e.g. Tuffen et al., 2002), most terrestrial sub-ice volcanoes are mafic…

The Valles Marineris is a system of canyons located just south of the Martian equator. The system is about 4000 km long, and, if on earth, would extend all the way across the United States. The…
