Last Updated: November 2, 2009

After the departure from the International Space Station (ISS) in the early hours of October 31, the HTV-1 continues smooth flight.

HTV-1 mission's Flight Day 53 (FD53) began at 9:00 a.m. November 1, and this is the day the HTV-1 enters the earth's atmosphere and completes the mission. The HTV-1 began the first de-orbit maneuver at 11:55 p.m. November 1, and completed the maneuver just as planned at 0:03 a.m. November 2. This was the first of three planned de-orbit burns that are for lowering the HTV-1's orbit altitude toward its atmospheric re-entry.

The second de-orbit maneuver is scheduled to begin at 1:25 a.m. November 2.
