Japanese mission overview of JERS and ASTER programs

摘要

Abstract: JERS-1 is an Earth observation satellite to be launched in February of 1992. The fundamental concept of the JERS-1 is to develop a satellite equipped with geologically oriented sensor systems truly based upon the user's requirements. The JERS-1 is expected to provide world- wide high-resolution data, which will be useful for not only nonrenewable resources exploration, but also agriculture, forestry and fishery, disaster prevention, environmental monitoring, and so on. ASTER is a research facility instrument to be on-board NASA's Eos-A platform in 1998, and inherits the technologies developed for the JERS-1. The ASTER instrument will provide valuable data for Eos key science tasks such as surface compositional mapping and surface process quantification and/or monitoring.!
