Richard Branson Plans To Travel To Space By July

British billionaire Richard Branson plans to travel to space within the next four or five months aboard his own Virgin Galactic spaceship, he told AFP Thursday.

"My wish is to go up on the 50th anniversary of the moon landing, that's what we're working on," the head of the Virgin group said on the sidelines of an event to honor Virgin Galactic at the Air and Space Museum in Washington.

The American Apollo 11 mission landed on the moon July 20, 1969.

Virgin Galactic is one of two companies, along with Blue Origin, on its way to sending passengers into space -- though just barely, and just for a few minutes.

The companies want to send hundreds or thousands of people on these short "suborbital" flights, meaning they wouldn't get high enough to orbit the earth.

These missions would be shorter and more affordable than SpaceX's planned project to send a Japanese billionaire to the moon by 2023 at the earliest.

Virgin Galactic flew 50 miles (80 km) above the earth, which the US considers the edge of space, for the first time in December (the international consensus is 100 km).

Virgin Galactic's spaceship, called SpaceShipTwo, is commanded by two pilots.

To take off, it's dropped by a carrier plane like a bomb, then starts its own engine to jet off straight into the sky, eventually climbing high enough to see the curvature of the earth.

The craft hovers and descends naturally, gliding back towards its original departure point, Mojave Air and Space Port in California.

It will be able to carry six passengers along with its two pilots.

Branson has previously announced dates for this first trip into space, though they've always come and gone without the voyage happening.

But this time the businessman claims preparations are in their final stages.

"By July we should have done enough testing," he said.

But he doesn't want to make any promises he can't keep: "I need to wait for our team to say they're 100% happy. I don't want to push them," he said, but thinks they'll be ready for clients by the end of the year.

He told AFP Virgin Galactic costs him $35 million a month; previously, he said he had invested more than a billion dollars in the venture since the 2000s.

According to Branson, the SpaceShipTwo's next test flight is planned for February 20, depending on weather conditions.
