The launch of the H-II Transfer Vehicle "Kounotori 2" (HTV2) Japanese resupply mission to the International Space Station has been rescheduled for tonight at 10:37 Phoenix time (05:37 UTC 22 February). Weather conditions were forecast to exceed launch restrictions.

A months long contest resulted in the nickname "Kounotori", meaning "white stork"

NASA TV will carry the launch live.

The Japanese HII-B launcher has now been rolled out to the launch pad and is undergoing fueling and system checks.

You can follow the Tanegashima Web Cam for current images of the launch site.
