For the structure of this chapter we chose to discuss the terrestrial planets and their satellites in terms of their geological evolution with time. We start with ancient times and end with modern times. Orthogonal to this time line, we describe the processes and their effects acting on each planetary body. Our home planet, Earth, serves as a reference

AIP Conference Proceedings, 2004
We present optical simulations of a new approach to directly image terrestrial planets. Terrestrial planets typically are 10 orders of magnitude fainter than the central star, a difficult challenge for any optical system. Our studies show that the combination of an external occulter and an apodizer yields the required contrast, with significantly ...

AIP Conference Proceedings, 2004
Some of the astronomical and cosmochemical constraints on the formation of the Sun’s terrestrial planets are reviewed, and the planetesimal theory of planetary accretion is described. Several difficulties remain for this model, especially in its earliest stage, but substantial progress has been made in recent years.

Terrestrial Planet Finder coronagraph
SPIE Proceedings, 2003This paper and oral presentation will describe the technology studies, the testbeds, and the architecture studies that will enhance the understanding and viability of a Terrestrial Planet Finder Coronagraph. Topics to be described fall in two categories: technology development and coronagraph mission design. The focus of the paper will be explanation

Mercury, the innermost planet, had been known since ancient times and its phases had been seen with early telescopes. Unfortunately, Mercury is a difficult object to observe, as it is always too low down in the sky when the Sun is below the horizon, and its image is consequently disturbed by the Earth’s atmosphere. As a result, it had proved impossible

The terrestrial planets (Mercury, Venus, Earth, and Mars), also called the inner planets, occupy the region within 1.5 AU from the Sun. They exhibit manifold properties of their surface landforms, geology, interiors, and atmospheric features. The Earth possesses a unique nature; the natural conditions of our neighbors Venus and Mars are completely ...
