Voyager’s structure: How is it made? Pt. 7

Summary

BUS, CRS, High-Gain Antenna, ISS, IRIS, LECP, LEMPA, MAG, Optical Calibration Target, PPS, PLS, PRA, PWS, RTG and UVS…What do these acronyms stand for? Every week (from now till November) I’ll post some components that are part of the Voyager. So stay tuned and let’s get started with RTG and UVS. Continue reading…

Radioisotope Thermoelectric Generators (RTG)

Three RTG units, electrically parallel-connected, are the central power sources for the mission module. Each RTG is made up of an isotopic heat source, a thermoelectric converter, a gas pressure venting system, temperature transducers, connectors, a heat rejecting cylindrical container, and bracketry. The RTGs are mounted in tandem (end-to-end) on a deployable boom as part of the MM.

Ultraviolet Spectrometer (UVS)

The UVS is a very specialized type of light meter that is sensitive to ultraviolet light. It determines when certain atoms or ions are present, or when certain physical processes are going on. The instrument looks for specific colors of ultraviolet light that certain elements and compounds are known to emit.
