Talk:H-II Transfer Vehicle

[edit] Simplicity
I think that the assumption that the HTV is simpler than the Progress since it performs berthing rather than docking like the Progress is by itself a rather simplistic statement.
The berthing requires station keeping of the HTV in the vicinity of the ISS, which is a risky operation. Grappling of a 15-ton free flying object by the SSRMS is an operation, which has never been attempted before.
It is not comparable to grappling of a satellite by the Shuttle arm, because Shuttle offers direct visibility and more maneuverability than the ISS.

[edit] H-II series
There should be an H-II series article about the program and related rockets. 70.55.89.134 (talk) 07:41, 12 April 2008 (UTC)
