On September 18,
2009 the Japanese HTV unmanned supply spacecraft was successfully berthed at
the International Space Station (ISS) at 10:49 a.m. Japan Standard Time, JST (on
September 17 at 22:49 UTC).
The ISS crew
marked this event by canceling several covers with the board postmark dated
the day of HTV docking.
All members of
the ISS crew autographed the covers. It is necessary to remark that the covers
were not delivered by the HTV. The covers were delivered to the ISS by a
Russian cosmonaut aboard a Soyuz TMA spacecraft.
