The Space Interferometry Mission
The Space Interferometry Mission (SIM) will be 10-m Michelson interferometer in Earth-trailing solar orbit. AS a part of NASA's Origins program, it will be the first space-based optical interferometer designed for precision astrometry. As well as enabling forefront astronomical science, SIM will serve as a technology pathfinder for future Origins missions, such as the Terrestrial Planet Finder ...
متن کاملEuropean Forest Mapping with SAR Interferometry
Forest maps of three European regions were completed with ERS SAR interferometry. The test-areas are Bern (Switzerland), Lozère (France), and Tuusula (Finland), representing different European forest types and topographic regions. The mapping algorithms used were similar in all cases and well suitable for forest observation. In this contribution the methodology applied and the results achieved ...
متن کاملReliability Modeling for the Space Interferometry
Top-level reliability models have been developed for several recent configurations of the Space Interferometry Mission (SIM) and the results used in the decision process for selecting viable configurations for further study. For one configuration, closed-form solutions were obtained. For three configurations, Excel-based Monte Carlo models were developed. The agreement between the closed form a...
متن کاملGravitational Microlensing with the Space Interferometry Mission
The Space Interferometry Mission (SIM), with its launch date planned for 2005, has as its goal astrometry with ∼ 1 μ arcsecond accuracy for stars as faint as 20th mag. If the SIM lives to expectations it can be used to measure astrometric displacements in the light centroid caused by the gravitational microlensing in the events detected photometrically from the ground. The effect is typically ∼...
