At 0.19 (36), the landing site has the lowest albedo as determined from orbit of the entire landing ellipse. From analysis of broadband (0.4 to 1.0 μm) images from the MER Pancam; the average albedo measured from the surface is 0.25 ± 0.05 (10).

A martian solar day has a mean period of 24 hours 39 min 35.244 s and is referred to as a sol to distinguish this from a roughly 3% shorter solar day on Earth. A martian sidereal day, as measured with respect to the fixed stars, is 24 hours 37 min 22.663 s, as compared with 23 hours 56 min 04.0905 s for Earth. See www. giss.nasa.gov/tools/mars24/ for more information.

"Dust" is an imprecise term but is commonly used for material on Earth that is smaller than about 40 μm and that is transported primarily in suspension. Estimates for dust on Mars suggest diameters of a few micrometers, although these particles are thought to stick together in some cases, possibly by electrostatic charges, to form aggregates of larger sizes (37).

Ripples are bedforms composed of sand and granules that are moved by surface creep induced by the impact of saltating sands, whereas dunes are larger bedforms typically composed of finer sands and not formed directly by saltation processes.
