This paper discusses some recently published analysis of the rock distribution on Mars and its impact on the scaling of planetary rovers for Mars surface exloration.
The formation of the Nectaris basin is a key event defining the stratigraphy of the Moon. Its absolute age, therefore, is a linchpin for lunar bombardment history. Fernandes et al. gave a thorough account of the history of different samples thought to originate in Nectaris, with the upshot being there is little agreement on what samples represent Nectaris, if any. We are revisiting the effort to identify Nectaris basin impact-melt rocks at the Apollo 16 site, to model their emplacement, and to use these parameters to examine other sites where Nectaris impact melt is more abundant and/or more recognizable for potential further study.
Wind tunnel studies are integrated with field observations to better understand the processes and rates of rock abrasion on Earth and Mars and how these factors affect ventifact morphology.
Although rocks of andesitic composition at the Pathfinder site may represent samples of ancient Martian crust, inferences drawn about a necessary role for water or plate tectonics in their petrogenesis are probably unwarranted.
Discussion of experimental apparatus and results of a dynamic penetration study of crushed rock under atmospheric and vacuum conditions /see accession no. a-63 12763, issue no. 7/
Steel drill bit having terraces of teeth intersected by spiral grooves with teeth permits the boring of small holes through rock with low power. The cuttings are stored in a chamber behind the cutting head. Could be used as sampling device.
