ImagiNe floating boobies hahaha

Quite a long time, I think.

The problem is that sending someone into outer space is outrageously expensive. The bargain-basement cost to put anything into space is around $2,000 - $3,000 per pound. Getting it back in (usually) one piece adds to the cost; when the space shuttle was flying it cost $10,000 per pound.

Porn budgets, on the other hand, are ridiculously low. The average budget for a porn movie is about $20,000. This is because of the business model for porn, which dictates that every single movie has to make a profit, so they're shot as cheaply and quickly as they possibly can be.

There was a movie called The Uranus Experiment 2 made using the low rent form of zero-g, namely, flying an airplane in a parabolic arc, but they only have 20 seconds of real zero-g footage in the film.
