A Piece of Philly in Space

The last space shuttle launch will take place this Friday and there’s a Philly connection to this flight. No, it’s a not a pretzel, but a piece of history from the Franklin Institute —  a 5 pointed stainless steel star that is very thin and is a piece of the original dome of the Fels Planetarium. It’s a great opportunity for The Franklin to send a piece of the planetarium into space and when it comes back it will be displayed for all to enjoy. Also, one of the moons of Saturn is spewing salt water. What’s the theory on how this salt water geyser was created? And is this moon slowly losing all its water? Answers to these questions and much more on this week’s Sky Talk.
