Manned spaecraft will require a much improved ability to forecast solar particle events. The lead time required will depend on the use to which the forecast is put. Here we discuss problems of forecasting with the lead times of hours to weeks.
The Cassini spaecraft will be the first one to visit the Saturnian system in more than two decades after the unprecedented flybys of the Voyager spacecraft in 1980 and 1981.
The Mars Environmental Survey Mission (MESUR) is a low cost, near term missin to study: chemical compositon of the martian surface; structure and circulation of the martian atmosphere; and structure and dynamics of the martian interior.
This paper describes key features of the instrument, spacecraft, and mission design for the Precision Optical INTerferometer in Space (POINTS), which have evolved through studies at the Jet Propulsion Laboratory during the last few years. This paper complements others in theis volume that describe the POINTS instrument, its scientific objectives, and specific engineering concerns.
