Planetary science: Space-rock alert

Characterization of Rock Populations on Planetary Surfaces

Characteristics of rock populations on the surfaces of Mars and Venus can be derived from analyses of rock morphology and morphometry data. We present measurements of rock sizes and sphericifies made from Viking lander images using an interactive digital image display system. The rocks considered are in the gravel size range (16-256 mm in diameter). Mean sphericities, form ratios, and roundness...

Galactic planetary science

Planetary science beyond the boundaries of our Solar System is today in its infancy. Until a couple of decades ago, the detailed investigation of the planetary properties was restricted to objects orbiting inside the Kuiper Belt. Today, we cannot ignore that the number of known planets has increased by two orders of magnitude nor that these planets resemble anything but the objects present in o...

Planetary Science: A Lunar Perspective

Monumenti, Musei e Gallerie Pontificie. This illustrates the state of planetary observation at the beginning of the eighteenth century. Most of the succeeding advances in this field have occurred in the past decade. Preface The technical triumph of manned landings on the Moon and the return of samples from the lunar surface has provided scientists with a unique opportunity to advance our unders...
