The current RTG model is the Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG is based on the type of RTG flown previously on the two Viking landers and the Pioneer 10 and 11 spacecraft (the SNAP-19 RTG). It is designed to be used in either the vacuum of space or within the atmosphere of a planet.
For example, each atom of the Pu-238 isotope contains 144 neutrons, while each atom of the Pu-239 isotope contains 145 of these neutral particles. Radioactive isotopes are further characterized by their half-life, the time it takes for any given amount of the element to be reduced by half.

Once an isotope fuel pellet is installed in an RTG, it begins to decay radioactively, creating heat that is collected by heat distribution blocks. These blocks then send the heat to sets of thermocouples that convert the heat into useful electricity. Thermocouples have long been in use and are not particularly complex or nascent.
