Voyager’s structure: How is it made? Pt. 3

Infrared Interferometer Spectrometer and Radiometer (IRIS)

The IRIS actually acts as three separate instruments. First, it is a very sophisticated thermometer. It can determine the distribution of heat energy a body is emitting, allowing scientists to determine the temperature of that body or substance. Second, the IRIS is a device that can determine when certain types of elements or compounds are present in an atmosphere or on a surface. Third, it uses a separate radiometer to measure the total amount of sunlight reflected by a body at ultraviolet, visible, and infrared frequencies.

Low-Energy Charged Particles (LECP)

The Low-Energy Charged Particle experiemtn uses two solid-state detector systems mounted on a rotating platform. The two subsystems are the low-energy particle telescope (LEPT) and the low-energy
