Will Space Play in the 2016 US Election?

It might be only March of 2015, but the race (slog?) is on to be the next president of the United States. Only 589 days to go! It’s a race that some believe will cost the nation upwards of five billion dollars; that’s about 7.5 Mars missions for those of you out there counting. The campaign, though, is more than just a vehiNasa-logocle for terrible campaign ads and embarrassing debate gaffes; it’s also one of the few opportunities for the country to have a discussion about its  national priorities in the coming years.

You can be thankful that we bask in the glow of a relatively placid star. Currently about halfway along its 10 billion year career on the Main Sequence, our Sun fuses hydrogen into helium in a battle against gravitational collapse. This balancing act produces energy via the proton-proton chain process, which in turn, fuels the drama of life on Earth. [click to continue…]
