TOKYO (AFP) - Japan successfully launched Saturday an experimental satellite aimed at providing high-speed Internet access across Asia, even when terrestrial infrastructure goes down, the space agency said.

The domestically developed H-2A rocket carrying the Kizuna satellite was launched at 17:55 pm (0855 GMT) with no glitches from the Space Centre on Tanegashima island off the southern tip of Kyushu Island, southern Japan.

The communications satellite, expected to be in use for five years, separated from the rocket approximately 35 minutes after the launch, said an official of the Japan Aerospace Exploration Agency (JAXA) during a live broadcast.

The 342 million dollar-Kizuna will allow super-high speed data communications of up to 1.2 Gbps, which would make it the fastest in the world, the agency said.

That rate would translate to 150 times that of the average high-speed ADSL connection rate of 8 Mbps, or 12 times the speed of a fibre-optic communication delivery to a person's premises (FTTP).

The "Kizuna," which also means "bond" in Japanese, is expected to begin transmitting and receiving data with terrestrial infrastructures in July after completing preparations and confirming the satellite's safety.

Japan is looking to use the satellite to allow communication when a ground-based network is severed by a disaster in any Asian country, in which case it would be used to transmit data to crisis management offices.

The agency is hoping it can also be used as an educational or medical tool to reach people in remote or mountainous areas.

"The Internet is now an integral part of our lives; but its infrastructure levels vary. Urban areas ... have a better environment, whereas some mountainous regions and remote islands are not well-equipped," JAXA said on its website.

The satellite will enable students in Asian countries to communicate smoothly and with no time lag among one another, as if they were in the same classroom, it said.

The satellite will to last five years, an agency spokeswoman said.

The launch was delayed by one week after JAXA said it had discovered a problem with the gas jet thruster for its launch rocket.

Japan, like developing Asian powers China and India, has been stepping up its space operations and has set a goal of sending an astronaut to the moon by 2020.

Japan faced an embarrassing failure in November 2003, when it had to destroy a rocket carrying a spy satellite 10 minutes after lift-off because a booster failed to separate.

However, Japan's first lunar probe, Kaguya, was successfully launched last September, releasing two baby satellites which will be used to study the gravity fields of the moon among other projects.

The 55-billion-yen (500-million-dollar) lunar probe is the most extensive mission to investigate the moon since the US Apollo in the 1960s and 1970s.

Bet the pings are crappy though.

Internet access on the moon?

Wouldn't you need a massive powersource to actually send the data? Receiving is fine..but the transmission from your laptop or cellphone, to space, would kill any batteries currently in use (I think). How good could it be if your phone can only handle 10 min of use (if that)?


--Perhaps it is meant as a last resort backup system.

I believe what this is actually for is allowing a uplink center to be built which can then run land based lines to customers in remote areas without having to build a big trunk up to that remote area (or undersea cables to islands)

So I don't think this is something that the average user is connecting to directly -- just an ISP of sorts -- though I suppose it could be possible to create a series of reception stations (think cell towers) that your wireless device connects to (massive wifi hotspots) that then transmit the data in a land based manner to the satelite uplink/downlink station.
