Successful berthing of the H-II Transfer Vehicle "Kounotori 4" (HTV4)
to the International Space Station (ISS)
The H-II Transfer Vehicle "Kounotori 4" (HTV4), launched from Tanegashima Space Center by the H-IIB launch vehicle 4 on August 4, 2013, has successfully berthed to the International Space Station (ISS) as planned.
This was the first time that I witnessed its berthing operation, which has been receiving very high appreciation from other space agencies, and I shared the joy of success with the "Kounotori" operation team members in the control room at Tsukuba Space Center.
With the successful berthing to the ISS, we have marked a significant milestone in "Kounotori 4" mission. We will be making efforts toward the achievement of all remaining mission operations including transfer of cargo, departure from the ISS, and re-entry into the atmosphere.
