These days, I have to seriously consider the possibility that you're part of a paid smear campaign by one of Musk's competitors. Because that's actually done these days. Ethical standards in marketing, never very high in the first place, have slipped that far. I suppose it's not the ethical standards of marketers that bother me so much, it's the public acceptance of such methods.
I have to agree with you. I have been watching Musk and his companies for a long time, and it seems to me that these trolling posts about Space X seemed to start appearing at a particular time, I think about two to three years ago. ULA, Space X's competitor in the US hired S-3 Group as a their propaganda and lobbying company about that time. I think what may have provoked it was that Space X was calling out ULA for using Russian rocket engines in its Atlas V rocket. They were involved in legal motions to prevent the Air Force from buying Russian engines. It seems to me that ULA likely realized that Space X was a real competitor. They likely wrote them off before as a joke because they Elon Musk kept making promises that seemed impossible. However those promises started coming true, albeit a bit later than promised. One thing that I have learned about Elon Musk is that he may make pronouncements that seem impossible, but usually they come true. He is quite brilliant and for the most part honest in what he says. He predicted that Space X would become a globally competitive launcher during a speech he made after their first successful launch, and this has come true. He predicted they would be able to land a first stage, and they succeeded last month. He predicted they would make a capsule that would land like a helicopter, and so far testing looks promising. I know the Mars idea seems unlikely at first glance, but if re-usability pans out (which seems likely because he has landed a first stage, which is the hardest part), then sending three or so astronauts on a fly-by won't be that expensive. Building a lander would be hard, but their experience with supersonic retropropulsion will help, as will their experience landing rockets. As for making fuel on Mars, I think that would require time and testing. I suspect the first flight will be a fly-by, just as it was with the Moon program. That is definitely feasible in the 10-year time frame.
