Mars Rover options

The paper will describe a nested set of Mars Rover options which are being considered. The option ranges include: low-to-high levels of technology, especially in autonomous activities; low (400 kg) to high (1500 kg) allowable mass; and coarse (100-meter) to fine (1-meter) knowledge of the terrain to be traversed. The options which will be selected for further study at the end of FY 1988 will be heavily dependent on such factors as the availability of precursor mission data (especially imaging) and the bounds on mass and volume imposed by the launch, Martian entry, and landing systems.
