Replica NASA Plutonium Pellet

This week I found a picture of a plutonium “pellet” that NASA uses to power everything from the Voyager spacecraft to Mars rovers. I found these little radioactive marshmallows beautiful and fascinating, - and I wanted my own. I researched the actual size and built one, complete with a NASA storage container.

The pellet was built in Fusion360, printed on my Mars Pro molded and cast in red tinted resin. The canister is scrap plumping bits from the shop. Pretty much a one-day build with stuff I had sitting around.

Very cool! My grandpa worked on the RTG for the Galileo probe which used that type of Plutonium, though not sure if it was pellets.
