I don't have to tell you that the southwest is in the midst of a record drought, some 14 years in the making, which means the water supply for many Western states - California, Arizona, Utah, Nevada - is drying up. Last month the Bureau of Reclamation announced they're cutting the flow of water into Lake Mead, which has already lost 100 feet of water since the drought began.
This is SCIENCE FRIDAY. I'm Ira Flatow. It's one of the most enduring questions in modern space exploration, a puzzle scientists have been trying to solve for years. Are we there yet? Where is the Voyager 1 spacecraft? Where is it right now in relationship to where we are?
