I still think challenging the current notion in the science community at large, that anti-philosophy, hard-core materialism (And the Cynicism that usually goes with it these days.) doesn't really represent science accurately. It creates a divided environment between science and religion when there really shouldn't be one. It distances people from science when it shouldn't, and distances others from religion/spirituality and philosophy when it shouldn't.
Philosophy has been driving science for decades, and we still need especially considering the weight of our recent advances. Genetics, Information Collection, Statistics(Eavesdropping, wiretapping, etc), Nano-technology, Cloning etc, Philosophy is the forum to discuss these and other issues IMHO, and that may be argued, but it has done a pretty good job so far.
Science doesn't belong to one group of people, it's the collective advancement of humanity.
And back on topic I actually love NDT, and space/philosophy that goes with it. Loved Sagan too, total trek-nerd, one of my secret wishes is to discover aliens within our life-time, (Or be alive for the advent of a warp-drive/Replicator).
