Are you libertarian?
No, but the speaker in your video is an ignoramous when it comes to innovation and progress. That comes from individual liberty and privately allocated capital, not from politically motivated spending.
deGrasse Tyson is a leftist supporting big government.
His dad was director of http://en.wikipedia.org/wiki/HARYOU He’s never held a job outside of academia or government according to his bio.
His mentors are also leftists and pro-government. Carl Sagan opposed Pres. Reagan’s SDI. You can find that here: http://en.wikipedia.org/wiki/Carl_Sagan#Personal_life_and_beliefs
deGrasse Tyson’s own information is here: http://en.wikipedia.org/wiki/Neil_deGrasse_Tyson
He is agnostic, but only because firm proof against the existence of God cannot be found.
He is anti-religion and participated in this conference here: http://en.wikipedia.org/wiki/Beyond_Belief:_Science,_Religion,_Reason_and_Survival
I would be careful to support political control of the sciences at all and NASA specifically. We don’t need them. Additionally, as a conservative you should be focused on the Constitution. NASA is unConstitutional.
Government injects politics into everything it does. Kennedy used space and NASA as a political tool. Look at the Food Pyramid, global warming, or the EPA for current examples of political abuse of science.
