Telecommunications IT and navigation for future Mars exploration missions

There are three primary drivers behind current investments in telecommunications information technology and navigation for Mars exploration. One is finding ways to maximize the volume of science data return since instrument data generation often exceeds communication bandwidth. Another is to provide the necessary technology to enable networked spacecraft. The third is to enable more precise landing so in-situ vehicles can be placed in more scientifically interesting regions. This paper describes current NASA investments in these areas funded through the Mars Technology Program (competed via NASA Research Announcements). Current investments are in stereo image compression, next generation Mars relay protocols, and a capability for autonomous approach navigation using in-situ Mars orbiter assets
