The 58-year-old billionaire intends to conduct a ceremony 70 miles above the Earth on the first Galactic sub-orbital flight next year.

He has already officiated at one wedding in mid-air. Last year he was ordained for the day in an online church to marry Virgin America marketing director Dimitrios Papadognonas and Coco Jones on a Virgin flight from San Francisco to Las Vegas

A spokesman for Virgin Galactic told The Mail on Sunday: "We have had two bookings involving marriage, one to get married in space and the other for the couple to have their honeymoon in space.

"It is possible that Richard could obtain a licence to conduct the marriage."

The Virgin Galactic space project is progressing at a dramatic rate and customers will take part in the first test flights this summer.
