Comment on Apollo Moon Landing Hoax – Why Fake a Moon Landing? by jfb.
The third reason is that it’s still really *hard*. It’s not trivial to engineer manned spacecraft and man-rated launchers, even with the last 40 years of experience, and getting out of Earth’s gravity well is no easier now than it was then. Getting off the ground and to Earth orbit is literally more than half of the battle of any space mission. We’ve squeezed every ounce of performance out of conventional liquid and solid rockets we can get. There are systems that can feasibly be built with current technology and offer greater performance to orbit, but tend to be *very* environmentally unfriendly (nuclear thermal, pulsed nuclear).
