NASA eyes Japan's ISS supply vehicle

'Unofficial negotiations' to buy

NASA is reportedly negotiating to buy the Japan Aerospace Exploration Agency (JAXA) H-II Transfer Vehicle (HTV) as a means of ensuring it can fulfil its obligation to supply the International Space Station following retirement of the space shuttle fleet in 2010.

The H-II (see pic), which will be able to lift six tonnes of cargo, is slated for first launch some time during 2009, and will thereafter make one or two trips a year to the ISS. The vessel costs around ¥14bn ($131m, £66m) a pop.

While Reuters was unable to get a comment from JAXA, it explains that Yomiuri "quoted the space agency as saying it has been unofficially discussing the matter with NASA since February". ®
