Pornhub has launched a campaign through the crowdfunding site Indiegogo seeking $3.4 million to film an adult video in space for the first time ever.

So far, the campaign has fallen flat: it’s only raised $18,000 in three days, even though the site is offering perks ranging from T-shirts to props to a spacesuit worn by an actor for those that donate large sums, according to a Denver Post report.

The money would be needed to train and outfit the crew, consult with specialists, customize film equipment, and fund using a shuttle that will send them into space.

The film would star Eva Lovia and Johnny Sins. It will be called “Sexplorations” and would be released in late 2016, assuming the funding campaign actually is successful.

Pornhub admitted it’s unexplored territory having sex in zero gravity, but their research suggested it is perfectly physically possible.

Pornhub said they would be teaming up with adult studio Digital Playground in “joining the ranks of Armstrong and Gagarin by pioneering a one of a kind mission to defy gravity, make history, and push the boundaries of intergalactic ‘Sexploration’ by filming the first ever sextape in space,” the company said according to a Washington Post report.

Pornhub insists that it’s not just a publicity stunt, and the company really is serious about the endeavor, according to the Post.

Pornhub is the largest pornography site on the Internet. It is headquartered in Montreal and has been in operation since 2007. It has servers around the United States and in London.
