Techniques and Instrumentation for Detection of Exoplanets II.
The Terestrial Planet Finder (TPF) mission to search for exo-solar planets is extremely challenging both technically and from a performance modeling perspective. For the visible light coronagraph (the C) approach, the requirements for 1e10 rejection

The NASA Mars Exploration Rover mission will launch two scientific spacecraft to Mars in 2003. The primary goal of the mission is to obtain knowledge of ancient water and climate on the red planet. Each spacecraft will carry one rover with a mass of

A new, photon-sensitive, imaging array, the active pixel sensor (APS) has emerged as a competitor to the CCD imager for use in star and target trackers. The Jet Propulsion Laboratory (JPL) has undertaken a program to develop a new generation, highly

The most accurate instrument for spacecraft attitude determination is a star tracker. Generally, these are CCD- based instruments. Until recently, only first-generation units were available. However, these first-generation designs are limited to outp

A star tracker for a mission to the planet Pluto is described. Low mass, low power and high levels of performance are required at the lowest possible cost. These goals are achieved for the FY94 baseline Pluto mission by a modified, commercially avail

Charge-coupled devices (CCDs) have been used extensively in the past in star trackers and fine guidance systems. A new technology, the active pixel sensor, is a possible successor to CCDs. This technology potentially features the same sensitivity and
