Spectrometer & Instrument Box 


The next step was to build the spectrometer and the instrument box. I have produced a blueprint (figure 1) in 1/10 scale while I created 3D views with Gmax allowing to see precisely its positionning on the lunokhod body. The first step was to build the instrument box using 0.75 mm styrene sheet. Figures 2, 3, 4 and 5 show the construction process. For this part, it was fairly simple since it was a simple square box with no specific detail on it except the connector.

I then built the spectrometer which construction is shown on figures 6. Although mostly made out of styren, the connecting tubes between the main instruments and the two plates are made out of small telephone wire (figure 6d). Once completed surface primer was applied to the part (figure 7), since the main part of the spectrometer is not painted in chrome it was necessary to use adhesive tape as a stencil to protect areas to be painted in different colors (figure 8). Eventually th spectrometer was installed onto the Lunokhod (figures 9). This completed all instruments on the front part of the lunokhod.
