HTV-1 continues nominal rendezvous maneuvering toward final approach phase (September 17, 2009)
On Flight Day 8 (FD8), the HTV-1 is set to perform a series of rendezvous maneuvers toward the final approach to the ISS.
The HTV-1 Performed the First Height Adjustment Maneuver (September 16, 2009)
On Flight Day 7 (FD7), the HTV-1 successfully performed its first Height Adjustment Maneuver (HAM1) at 9:04 a.m. September 16. The HTV-1 is now flying in a near-circular orbit with apogee altitude 324 km and perigee altitude 305 km, as planned.
HTV-1 Approved for Proximity Operations and Final Approach (September 15, 2009)
Fight Day 6 (FD6), the HTV-1 continues the far-field rendezvous flight. Today, the International Space Station (ISS) Mission Management Team (MMT) approved the HTV-1's proximity operations and final approach. Having received the approval from the ISS program, the HTV-1 is set to perform its first Height Adjustment Maneuver (HAM) on Flight Day 7 (FD7) at 9:03 a.m. September 16.
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.
