McCallie said. "A group of people has contacted us about donating $3 million to our cause, but they wish to remain anonymous. What I can tell you is that these are some of the same people who invested in the commercial space-flight industry."
now that is interesting! you don't really stay anonymous for too long being an investor in commercial space industry and having the money to donate like this, so it shouldn't be that hard to figure out who they are.
curious to note that Patrick Stewart, ST:TNG Captain Picard, has publicly said that he would prefer to see money spent on space exploration instead put to use solving the worlds current problems on the planet itself! starvation, disease, etc.
