Summary
(Adapted from RST home page)

For 10 years, the writer's (NMS) principal scientific occupation was the study
of nuclear explosion craters and their natural counterparts, meteorite
(asteroid) impact craters. From the status 50 years ago of "minor curiosity",
impact cratering has now been elevated to be one of the three most important
geologic ... processes. About 150 craters are known on Earth (compared with
millions on the Moon that survive because tectonic and fluvial erosion
processes have not destroyed them). This second section on scientific uses of
remote sensing will delve into three topics: 1) what happens to make a crater;
2) how are impact craters found and recognized, and 3) can remote sensing help
to find more? During his remote sensing years, the writer has searched for new
ones but has come up empty. However, others have found a few previously unknown
craters intially on space imagery. Special processing of images also can reveal
subtle details about known craters that add to our knowledge of their size and
deformation characteristics.
