[TCM-3] The thruster injection for the first fine tuning adjustment is currently being performed. The results of TCM-3 will be reported after all confirmations are complete.

[TCM-3] At 15:36 JST, the timed command for transitioning onto the re-entry orbit for Woomera in Australia was sent to the spacecraft. Orbital transition injection is scheduled for about 16:00. The speed increase is planned to be 1.2m/s. After this, a fine adjustment is planned.

The Subaru Telescope has photographed the Hayabusa2 spacecraft from a distance of about 5.8 million km. Since the estimated magnitude is just 24.6 mag, this needed Subaru’s power. Thank you to everyone at the Subaru Telescope!(Hayabusa2 Project)

[TCM-3] There are about 20 members in the control room, and the operation is proceeding smoothly with no problems with the spacecraft nor ground station. Doppler data is displayed on the central screen in the control room; this will change with the use of the chemical thrusters.

[TCM-3] Today (Nov. 26), the TCM-3 operation began. The orbit of the Hayabusa2 spacecraft needs to be carefully controlled in order to enter the atmospheric entry orbit towards Woomera, Australia. A briefing was held before the start of operations at 11:40 JST & we began at 12:00

Tomorrow (11/26) we will perform TCM-3; a very important orbit control. The time to use the chemical thrusters is from about 16:00 JST, and the amount of acceleration will be about 1.2 m/s. Finally, the capsule will be an orbit back to Earth.

CRSO permission was granted based on a judgement that there are no issues with the navigation, guidance, plan, spacecraft or ground systems.

Today (11/25) we received permission from the Commonwealth Return Safety Officer (CRSO) to transition Hayabusa2 onto a re-entry trajectory towards the Australian Woomera Prohibited Area (WPA). (📷 Dominic Balasuriya & PM Tsuda at the Australia Embassy, holding the agreement.)

There was a rainbow in Adelaide the other day! It made us happy to see this little thing. We hope it will be fine on the day of the capsule collection.

It’s now less than 2 weeks left, and under 4,500,000 km to Earth! The current plan for the Earth return (in JST): ・December 5, 14:00 - 15:00: capsule separation ・Dec. 5, 15:00 - 17:00: orbit change for spacecraft departure ・Dec. 6, 02:00 - 03:00: capsule landing

We’ve released a summary of information on observing the sample capsule during re-entry to Woomera, Australia. There is also an app for iOS that displays the trajectory in AR. If you are in a location where you can see the re-entry, do check this guide.

The preliminary team for the capsule collection team has arrived a little earlier than the main team in Woomera. Majestic. The view looks like a postcard no matter where you look. (Collection Team M)
