Japanese billionaire Yusaku Maezawa said Thursday he had no fear ahead of his "dream-come-true" launch to the International Space Station (ISS), a Russian project aimed at boosting its space tourism credentials.

The mission is one of several this year by non-professional astronauts, including 90-year-old "Star Trek" actor William Shatner who on Wednesday completed a space flight on board a Blue Origin rocket.

Maezawa, 45, is the founder of Japan's largest online fashion mall and the country's 30th richest man, according to Forbes.

"I've got a list of one hundred things I want to do on the station like play badminton," Maezawa said at a news conference on Thursday.

"The closer it gets the more excited I get. I'm not afraid or worried," he said.

Maezawa and his assistant are set to blast off from the Russia-leased Baikonur cosmodrome in Kazakhstan in December, accompanied by Russia cosmonaut Alexander Misurkin.

A Russian Soyuz rocket on Thursday blasted into space carrying 36 new satellites from British operator OneWeb, which aims to provide broadband internet everywhere in the world.

The rocket, operated by Europe's Arianespace, took off at 0940 GMT from the Vostochny cosmodrome in Russia's Far East, broadcast live by the country's Roscosmos space agency.

"LIFTOFF!" Roscosmos tweeted after the launch—the seventh this year carrying OneWeb satellites.

OneWeb, a London-headquartered company, is working to complete the construction of a constellation of low earth orbit satellites providing enhanced broadband and other services to countries around the world.

The company is competing in the race to provide fast internet for the world's remote areas via satellites along with tech billionaire Elon Musk and fellow billionaire Jeff Bezos of Amazon.

The UK company plans for its global commercial internet service to be operational by next year, supported by some 650 satellites.

Arianespace, which has worked with Russia for close to two decades, is under contract to make 16 Soyuz launches between December 2020 and the end of 2022.

With this latest mission, a total of 358 satellites are now in orbit for the constellation, Roscosmos said.

Britain's Prince William has launched an attack on space tourism, urging more attention on problems closer to home ahead of the COP26 climate summit.

The comments by Queen Elizabeth II's grandson were airing in a BBC interview later Thursday, a day after "Star Trek" star William Shatner became a real space traveller on Blue Origin's second crewed mission.

The mission replayed the company's maiden human flight in July, which included its founder Jeff Bezos of Amazon and was seen as a breakthrough for the emerging space tourism sector.

But Prince William said: "We need some of the world's greatest brains and minds fixed on trying to repair this planet, not trying to find the next place to go and live."

Virgin Galactic, which offers a similar experience of a few minutes' weightlessness and a view of the Earth's curvature from the cosmos, launched its founder Richard Branson in July, a few days before Bezos.
