KOUNOTORI2 Continues Nominal Rendezvous Flight

Last Updated: January 25, 2011

KOUNOTORI2 maintains nominal orbital rendezvous flight. KOUNOTORI2 is now in an elliptical orbit at an altitude of 320km (apogee) x 312km (perigee). As of 11:00 a.m., January 25, KOUNOTORI2 is flying approximately 9,000km behind the ISS, shortening the distance to the ISS by approximately 230km per hour.

KOUNOTORI2 is slated to perform the first Height Adjustment Maneuver (HAM1) at 6:25 a.m., January 26, and two more height adjustment maneuvers on January 27, which will bring the KOUNOTORI2 to a point 5 km behind the ISS (Approach Initiation: AI). At the AI point, the KOUNOTORI2 will adjust timing to move to the final approach point below the ISS.

Capture by the station's robotic arm (Space Station Remote Manipulator System: SSRMS) is expected at 8:45 p.m. January 27. Berthing operations is expected to begin after 11:00 p.m. January 27, 2011.
