The Apollo 11 mission in 1969 was one of the most sophisticated scientific experiments of all time. This trip involved over 5 million lbs. of fuel for the round trip to our closest celestial neighbor. That worked well for getting us to the moon and back, but how much fuel could we possibly produce and carry on board for a trip to the distant reaches of our solar system? Listen to the latest Question Your World Radio Report from the Science Museum of Virginia to learn more about renewed production of a different fuel source - Plutonium 238.

Every living creature on Earth is designed, more or less, by four basic nucleic acids. These acids combined in various sequences and strands form our DNA, which dictates everything about us from our daily physiology to our biological rhythms, commonly referred to as our biological clocks. This clock controls when we’re active, when we eat, how we age, and so on.
