Neil deGrasse Tyson Touches Off Debate With Remarks On Commercial Space (theverge.com)
MarkWhittington writes: In an interview published in The Verge, celebrity astrophysicist and media personality Neil deGrasse Tyson touched off a firestorm when he suggested that commercial space was not going to lead the way to open up the high frontier. Tyson has started a live show that he calls "Delusions of Space Enthusiasts" in which he touched on, among other things, why the Apollo program did not lead to greater things in space exploration such as going to Mars. Tyson repeats conventional wisdom about Apollo and the Cold War. In any case, it is his remarks on commercial space that has caused the most irritation.
used to be they were only for governments and large corporations. now the military is buying the same tech as everyone else because it's better than their custom made stuff. same thing with commercial space. there will be a lot of investment which will drop the costs of launches and it will get ahead of NASA
I've listened to NdGT talk about this topic a fair bit and I agree with his basic thesis that private companies will not lead the way to Mars or even the Moon. You simply cannot make a credible business case for a private company to do it. I'm an engineer but I'm also a certified accountant. I've pitched investors on projects and the problem is largely an economic one. Paraphrasing his arguments the risks are large and substantially unquantifiable, the ROI is unknown and will take many years if not decades and the amount of money required for large exploration projects is huge. The only institution which is in a position to spend large amounts of money on something with big risks, huge costs and completely uncertain payoffs are governments. Once some of the risks have been quantified and enough information becomes available to make a reasonable guess at an ROI and time frame for the investment, THEN private enterprise can jump in.
We largely admire companies like SpaceX but SpaceX isn't doing anything wildly outside what NASA has already done. They're not sending probes to Mars, they are just improving the economics and a bit of the technology for chemical rockets - a technology we've had for 60+ years. People talk about mining asteroids but no private body is funding the exploration to go find them much less developing the technology to actually do something economically useful. The cost is too big, the returns too uncertain and the risks are still largely unknown. It's why we still need NASA out there on the frontier. Leave the launches to SpaceX and others and get NASA out into the solar system doing the cutting edge research and exploration we so desperately need. We don't need NASA building rockets, we need them figuring out how to get us permanently more than 200 miles from the surface of the Earth.
