Autonomous optical navigation using nanosatellite-class instruments: a Mars approach case study

Since the beginning of human history, Mars has been an alluring dream—the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. But all that changed when leading space exploration authority Robert Zubrin crafted a daring new blueprint, Mars Direct. Unlike the dead world of the Moon, the Martian landscape is filled with possibility, but humans must be able to survive there. In the grand tradition of successful explorers, Zubrin calls for a travel-light and live-off-the-land approach to Martian settlement. As the landmark mission of the Mars Science Laboratory begins, Zubrin lays out a comprehensive plan to build life on a new world.

The Case for Mars is, according to Zubrin, a comprehensive condensation for laymen of many years' work and research. Chapters one and four deal with Mars Direct most completely.

Celestial Mechanics and Dynamical Astronomy. February , Cite as. This paper examines the effectiveness of small star trackers for orbital estimation. Autonomous optical navigation has been used for some time to provide local estimates of orbital parameters during close approach to celestial bodies. These techniques have been used extensively on spacecraft dating back to the Voyager missions, but often rely on long exposures and large instrument apertures.
