Impact History of Eros: Craters and Boulders
Preliminary measurements of craters and boulders have been made in various locations on Eros from images acquired during the first nine months of NEAR Shoemaker’s orbital mission, including the October 2000 low altitude flyover. (We offer some very preliminary, qualitative analysis of later LAF images and very highresolution images obtained during NEAR’s landing on 12 February 2001). Craters on...
متن کاملMorphological Features-Based Descriptive Index System for Lunar Impact Craters
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence for both the current state and evolution history of the Moon. Current description methods for lunar impact craters are predominantly qualitativ...
متن کاملImpact Melt Volumes in Simple Lunar Craters: Constraints on Modeling
Introduction: Impact melt is a typical product produced during the cratering process as a result of the intense heating of the target usually because of pressure decompression, but also possible because of shear heating (Figure 1). Melt is observed on all of the terrestrial planets in both simple and complex craters [16]. High-resolution data for the Moon now allows impact melt deposits to be c...
متن کاملASYMMETRIC STRUCTURE OF LUNAR IMPACT CRATERS DUE TO OBLIQUE IMPACTS? M.Goeritz
Introduction: It has long been a matter of debate whether there exist any characteristic features in crater morphology diagnostic for oblique impacts [e.g. 1,2]. The vast majority of impact craters are almost circular in plain view, although it is well known that most impacts occur at an oblique angle of incidence [3]. Impact events may be approximated as a stationary point source of energy and...
متن کاملEffect of impact velocity and acoustic fluidization on the simple-to-complex transition of lunar craters
We use numerical modeling to investigate the combined effects of impact velocity and acoustic fluidization on lunar craters in the simple-to-complex transition regime. To investigate the full scope of the problem, we employed the two widely adopted Block-Model of acoustic fluidization scaling assumptions (scaling block size by impactor size and scaling by coupling parameter) and compared their ...
