HTV-1 Maintains Smooth Flight（September 14, 2009）
Flight Day 5 (FD5), the HTV-1 is continuing the smooth flight. Tomorrow, Flight Day 6 (FD6), the result of the HTV-1 demonstration tests will be reviewed at the ISS Mission Management Team (IMMT) meeting. In the meeting, safety and flight control abilities of the HTV-1 will be assessed based on the data collected during the demonstration tests conducted on FD3. When the IMMT gives an approval for the HTV-1's final rendezvous approach, the HTV-1 is set to perform the first Height Adjustment Maneuver (HAM) on FD7 toward the ISS.
CAM Demonstration Concluded with Great Success（September 12, 2009）
The Collision Avoidance Maneuver (CAM) demonstration went quite smoothly. The last maneuver took place at 4:34 p.m.,September 12, and with that, the HTV-1 concluded all the CAM tests. The HTV-1's systems functioned well throughout the demonstration, proving that the HTV-1 could safely move away from the International Space Station (ISS) in case of any emergency during its final rendezvous phase. The data obtained during today's demonstration will be reviewed at NASA's ISS Mission Management Team (IMMT) meeting on FD6 for approval for the HTV-1's final approach to the ISS. The next HTV-1 Mission update will be posted on September 14.
HTV-1 Began Demonstration Tests（September 12, 2009）
With the start of FD3, demonstration tests of the HTV-1 began at 10:12 a.m. September 12. Today's demonstration includes HTV's Collision Avoidance Maneuver（CAM）operations, a series of contingency maneuvers that may be needed in case of emergency during the HTV-1's final rendezvous phase. All the maneuvers are expected to be completed by 4:33 p.m. September 12.
HTV-1 Mission Flight Day 2（September 11, 2009）
The HTV-1, inserted into the planned elliptical orbit on FD1, has been continuing a smooth flight on FD2. Today, the HTV-1 performed the first rendezvous maneuver at 9:33 a.m. to raise its orbital altitude toward the ISS. Approximately two hours later, the HTV-1 reached the targeted orbit. While flying in this orbit, the HTV-1 will perform demonstration tests planned on FD3. The next HTV-1 Mission updates will be posted on Saturday morning, September 12.
HTV in Good Health（September 11, 2009）
After establishing the communications with the ground, The HTV-1 has successfully established 2-axis attitude control at 2:42 a.m. and 3-axis attitude control at 3:16 a.m. September 11. The HTV Flight Control Team (HTV FCT) has now been checking the telemetries of the HTV-1's subsystems in preparation for the first rendezvous maneuver planned on the FD2 around 9:30 a.m. September 11.
Communications Successfully Established（September 11, 2009）
On the planned orbit, the HTV has established communications with the NASA's TDRS and initiated communications with the HTV Mission Control Room (MCR) at Tsukuba Space Center (TKSC).
