Making trips to the moon, let alone Mars, is pretty dangerous for the pilots involved. We lack the technology to properly protect them from radiation from the sun. Apollo 11 was only a three day mission, yet if they had launched it a couple of days earlier or later it could have been tarnished by the crew being exposed to fatal levels of radiation. To get to Mars means we need to figure out a way to protect the crew.
As for the Concorde, it's been shown that supersonic air travel is damaging to the atmosphere. While military application outweighs such concerns, civilian travel just isn't important enough. Also, the Concorde was expensive as hell to operate, which isn't a good thing for an industry that's been struggling for awhile now.
And as far as SS1 is concerned, the only interesting thing about it is that it's privately developed technology rather than military developed. It's not much more amazing than the X15 which went into space in pretty much the same fashion.
Anyway, while you're right that that major innovations haven't come along in awhile we've sure gotten better at the ones we've got. I wouldn't expect major new developments until we can figure out the surviving outside of the magnetic field issue, and then it will probably be light sails or something irrelevant on Earth itself.
You do not have the right to never be offended.
