slide 4 How can it be used? Space Exploration!!!!!
How do they travel so far (energy for onboard systems)?
Slide 5 What types of energy are used?
One energy source is from RTGs onboard spacecraft
Slide 6 Radioisotope Thermoelectric Generators (RTGs) [Image from JPL website of RTG]
slide 7 RTGs and Radioactive Decay The RTGs power the spacecraft through the radioactive decay of plutonium-238. [Image from JPL website of RTG]
slide 8 RTGs and Radioactive Decay This decay emits heat, which is converted into electricity for the spacecraft to "see, sense, hear, and speak."
This power supplies a reliable, long-lasting source of electricity which is insensitive to the chilling cold of space and virtually invulnerable to high radiation fields, such as Earth's Van Allen belts and Jupiter's magnetosphere.
slide 9 Radioactive Decay Questions What does the process look like? Whats a half-life?
