Virgin Galactic is not really a space ship, it's just a pressurised aeroplane with a rocket on the back. It goes up, vertical, into space, then falls
back down again - which is why participants experiance zero gravity. It shall be noted this is relatively easy, and is the reason it doesn't burn up.
Proper, space programme rockets have to put satellites in orbit, which means attaining an orbital speed of perhaps, 28,000km/h, a few hundred
kilometres high - so that basically the centrefugal force is balanced with gravity, so your pretty much falling around the Earth in zero G. Obviously,
to attain this speed, much of it has to come from when inside the outskirts of the atmosphere, which is hugely stressful and energy intensive - this
is the reason why we don't have civilian space programmes with people into space. It would cost a heap of money, particularly developing everything
from scratch.
To get to the moon? The most efficient way to get to the moon is lunar transfer orbit. You acheive low earth orbit around the earth, then, align
orbital planes so that your space crafts ground track matches the orbit of the moon (You could eliminate this step with a well picked launched point.)
Obviously if you're going 28,000km/h, it's going to need a
HUGE amount of energy to even change your course a single degree. Next, you need
the highest point of your orbit to be the same as the moon, at minimum, 363 104 km from Earth, by comparison, low earth orbit is a minimum of 140km.
That too, is going to require a
HUGE amount of energy. Due to various reasons you're going to need further burns to acheive lunar orbit, but
it would take too long and beat a dead horse.
There are a couple civlian companies that shoot satalites into space, but these are mostly relatively small rockets, not much more capable than
putting a few hundred kilograms into orbit - the Saturn V, moon rocket, could put 118,000 k to LEO, and 47,000 kg to 'Lunar Vicinity'. That was a
big rocket, and a very expensive programme ,$32-45 billion in 2007USD. Even countries that the Chinese haven't (yet) accomplished.
In short, the only reason we haven't gotten civilians on the moon, or even a civilian satellite close, is because of the technical difficulties and
the massive cost. We need return on investment, and if it's a rocket that just goes to moon for some pictures, then it will be likely very hard to
justify the price of it. Don't get me wrong, it IS possible, and WILL happen, the question is when, and at what cost. IF you can get past the
technical difficulties, I doubt the government could really do anything about you,
as there are many civlian rockets out there.
Hope this helps.
