Analyses of Rock Size-Frequency Distributions and Morphometry of Modified Hawaiian Lava Flows: Implications for Future Martian Landing Sites
Both the size-frequency distribution and morphometry of rock populations emplaced by a variety of geologic processes in Hawaii indicate that such information may be useful in planning future landing sites on Mars and interpreting the surface geology.
Mars Pathfinder Landing Site Workshop
The Mars Pathfinder Project is an approved Discovery-class mission that will place a lander and rover on the surface of the Red Planet in July 1997. The Mars Pathfinder Landing Site Workshop was designed to allow the Mars scientific community to provide input as to where to land Pathfinder on Mars. The workshop was attended by over 60 people from around the United States and from Europe. Over 20 landing sites were proposed at the workshop, and the scientific questions and problems concerning each were addressed. The workshop and the discussion that occured during and afterward have significantly improved the ability to select a scientifically exciting but safe landing site on Mars.
Science strategy and rationale for robotic missions to Mars
The scientific rationale for robotic missions to Mars follows a strategy in which a global data set and general understanding of the planet proceeds to progressively greater detail about specific scientific questions and candidate landing sites. In particular, a global understanding of Mars will be obtained from the Mars Observer mission and the Network Mission. The Site Reconnaissance Orbiter and the Sample Return mission will allow extensive testing and reevaluation of the knowledge about Mars and potential landing sites. Finally, a number of Rovers will provide detailed information on trafficability, resource availability, habitability, and science potential of candidate landing sites. The robotic mission set will also identify important scientific questions that can be addressed at potential landing sites.
Geologic implications of spectrophotometric measurements of Europa
Photometric functions and reflectances have been obtained from spectrophotometric measurements of Voyager images of Europa for (1) six mapped geologic terrains, (2) three types of lineaments, and (3) the brown spots. The results thus obtained suggest that Europa's materials fall into two main categories: a comparatively clean ice that constitutes the plains, and a darker and redder, silicate-rich material that makes up the brown spots and the wedge-shaped bands. Reflectance profiles obtained across the wedge-shaped bands and triple bands indicate similar albedo and color changes, implying similar structures for both of these features.
