Japanese start-up aims to rival SpaceX with new balloon capsule that can float passengers to space

Japanese start-up aims to rival SpaceX with new balloon capsule that can float passengers to space

A Japanese startup announced plans on Tuesday to launch commercial space-viewing balloon flights that it hopes will bring an otherwise astronomically expensive experience down to Earth.

CEO of Iwaya Giken, Keisuke Iwaya said passengers do not need to be billionaires, go through intense training or have the language skills needed to fly in a rocket.

"It’s safe, economical, and gentle for people," Iwaya told reporters. "The idea is to make space tourism for everyone.” He said he wants to "democratise space".

The company, based in Sapporo in northern Japan, has been working on the project since 2012 and says it has developed an airtight two-seat cabin and a balloon capable of rising up to an altitude of 25 km, where the curve of the Earth can be clearly viewed.

While passengers won't be in outer space - the balloon only goes up to roughly the middle of the stratosphere - they'll be higher than a jet plane flies and have an unobstructed view of outer space.

The company teamed up with major Japanese travel agency JTB Corp, which announced plans to collaborate on the project when the company is ready for a commercial trip. Initially, a flight would cost about 24 million yen (€167,000), but Iwaya said he aims to eventually bring it down to several million yen (tens of thousands of euros).

Making space more accessible

While Japanese space ventures have fallen behind US companies like SpaceX, Iwaya said his aim is to make space more accessible.

SpaceX launched three rich businessmen and their astronaut escort to the International Space Station (ISS) in April for $55 million (€51.5 million) each - the company's first private charter flight to the orbiting lab after two years of carrying astronauts there for NASA.

But unlike a rocket or a hot air balloon, the Iwaya Giken vessel will be lifted by helium that can be largely reused, company officials said, and flights will safely stay above Japanese territory or airspace.

The first trip is planned as early as later this year.

The balloon, which can carry a pilot and a passenger, would take off from a balloon port in Hokkaido, rise for two hours to as high as 25 km and stay there for one hour before a one-hour descent.

The drum-shaped plastic cabin is 1.5 m in diameter and has several large windows to allow a view of space above or the Earth below, the company said.

Applications for a space viewing ride opened on Tuesday and will continue through the end of August.

The first five passengers selected will be announced in October, company officials said, and flights will be approximately a week apart, depending on the weather.
