The aim was to lampoon the suggestibility of public figures willing to repeat, with feeling, any nonsense they are told, the bogus gravity of much current-affairs television, the hypocritical voyeurism of media coverage of sex and crime, and a lot else besides.

Hundreds of scientific papers have been written on the Pioneer anomalies, many of them trying to find explanations beyond the current laws of gravity.

As much as we wish this was some type of anti-gravity bouncy castle, NASA's current experiments with inflatable structures are intended for slightly less entertaining implementation on the moon, where crews will use them as outposts for research, testing, storage, and living.
