The Mars Telecommunications Orbiter (MTO) was intended to provide high-performance deep space relay links to landers, orbiters, sample-return missions, and approaching spacecraft in the vicinity of Mars, to demonstrate interplanetary laser communications, to demonstrate autonomous navigation, and to carry out its own science investigations. These goals led to a need for an array of end-to-end information...
The UHF relay link through the Mars Odyssey orbiter exceeded expectations of the Mars exploration rover (MER) project and played a critical role in the return of data from the surface of Mars and in the accuracy of the rover position determination. This paper will discus the development and performance of the UHF transceivers and the Consultative Committee for Spacecraft Data Systems (CCSDS) Proximity-1...
Mission operations for the Mars Observer project were patterned after the low-cost approach proposed under the Planetary Observer program of the early 1980s. That approach was based on: a mission with focused science objectives; a repetitive mapping operation; a high-heritage spacecraft design; a science payload with low demands on the spacecraft for resources and control; utilization of data standards...
