1 Summary of Results from the Risk Management Program for the Mars Microrover Flight Experiment

Autor: Jacob R. Matijevic, Robert Shishko

Publikováno v: INCOSE International Symposium. 9:428-439

On 4 July 1997, the Mars Pathfinder landed on the surface of Mars carrying the first planetary rover, known as the Sojourner. Formally known as the Microrover Flight Experiment (MFEX), the Sojourner was a low cost, high-risk technology demonstration,

Evidence for Martian electrostatic charging and abrasive wheel wear from the Wheel Abrasion Experiment on the Pathfinder Sojourner rover

Autor: Mark W. Siebert, David M. Wilt, Jacob R. Matijevic, Dale C. Ferguson, Joseph C. Kolecki

Publikováno v: Journal of Geophysical Research: Planets. 104:8747-8759

The Wheel Abrasion Experiment (WAE) on the Mars Pathfinder rover was designed to find out how abrasive the Martian dust would be on strips of pure metals attached to one of the wheels. A specially modified wheel, with 15 thin film samples (five each

Most of the soil-like materials at the Pathfinder landing site behave like moderately dense soils on Earth with friction angles near 34°–39° and are called cloddy deposits. Cloddy deposits appear to be poorly sorted with dust-sized to granule-siz

Anomaly Recovery and the Mars Exploration Rovers

Autor: Jacob R. Matijevic, Elizabeth A. Dewell

Publikováno v: SpaceOps 2006 Conference.

The premise of the design of operations for the Mars Exploration Rovers (MER) is that the vehicles will drive each day. As a result, they will encounter some aspect of the terrain environment that cannot be anticipated or otherwise accommodated by th

Publikováno v: Journal of Geophysical Research: Planets. 108

[1] In January 2004 the Mars Exploration Rover mission will land two rovers at two different landing sites that show possible evidence for past liquid-water activity. The spacecraft design is based on the Mars Pathfinder configuration for cruise and

The Mars Exploration Rover: An In Situ Science Mission to Mars

Autor: Barry Goldstein, Jacob R. Matijevic, Richard V. Welch

Publikováno v: SAE Technical Paper Series.

In this paper the concept for a mobile vehicle system which performs an in situ science mission to Mars is described. This rover mission with its requirements for driving, positioning at science selected targets, and remote and in situ measurement wi
