Engineering Constraints
(See Golombek & Parker's memorandum for explanations.)
Parameter Constraint Comment
MER-A Latitude 15°S to 5°N  
MER-B Latitude 10°S to 10°N  
Elevation < -1.3 km MOLA-defined, relative to MOLA-defined geoid
Low-Altitude Winds, Wind Shear < 20 m/s  
Separation of Two Landing Sites >= 37° solid angle on the surface
Surface Slopes <= 15° in general
Surface Images appear hazard-free,
relatively smooth and flat
e.g. no fresh craters
Total Rock Coverage < 20% as derived from thermal IR measurements
Rocks > .5 m < 1%  
Radar Reflectivity > 0.05  
Fine Component Thermal Inertia > 3 - 4 x 10 -3 cal cm -2 s -1/2
K-1 or cgs units
equivalent to 125 - 165 J m -2 s -1/2
k-1 or SI units
Extremely high albedo and low thermal inertia regions should be avoided.
