If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Everyone, red state, blue state, everyone supports space exploration.

I get quite stroppy if I lose - but I've developed skills with a mind coach to help deal with the highs and lows of tennis at this level.
