Love the viking satellite, had to pick this up after seeing it listed. could be bigger but not complaining

Another model of something that, as far as I know, no kit exists. While this model is preassembled and painted, it's a decent representation. Be warned: It's very small; no scale is given, but model is about 3 inches long to the end of the (extended) sample scoop. Comes with a nice Mars terrain base, complete with sample scoop trench.

The model is quite small and comes with additional materials and a comic describing Viking 1.
