Thank you very much for your many messages and warm support for the “Goodbye Ryugu” Campaign (11/13 - 11/19). There are a few more messages from people involved in the project which we will share.

From today (11/20), work related to the trial operation of the ion engines has begun as scheduled. We will proceed with various tasks over the week.

A #SAYONARA_Ryugu from Shota Kikuchi (responsible for landing point selection): There were a hopeless number of rocks, but finally Ryugu gave us an opening to its heart of just a 3m in radius. Thank you for an exciting year and half! pic.twitter.com/CkKneAN2Le

I have been involved since the first Hayabusa spacecraft and I am full of gratitude that we were able to explore in this way. I will continue to do my best in the research for Hayabusa2 [2/2]

A #SAYONARA_Ryugu message from ONC team member, Tatsuhiro Michikami: With the Hayabusa2 team’s hard work and the support of everyone in the nation- and worldwide, We could safely finish our work at Ryugu. Thank you! I now just wish for a safe return of the capsule to Earth [1/2]

From Navigation Guidance Control, Takeshi Ohno, sends a #SAYONARA_Ryugu message: Now to the Earth. A frantic and ferocious dash!

From Dr Ernesto Palomba in Italy, #SAYONARA_Ryugu: 鳴な虫別るる恋はほしにさへ naku na mushi wakaruru koi wa hoshi ni sae don't cry, insects-- lovers part even among the stars Photo caption: To remember Ryugu a Bacio (Kiss) from Italy pic.twitter.com/iuM7KTZkZw

From TIR/SCI/DCAM3's Yuri Shimaki, a #SAYONARA_Ryugu message: A dark and rocky Ryugu. I was worried about locating the SCI crater, but it made a fine hole. The impressions and excitement of seeing the DCAM3 images in the operation room made an unforgettable day. Until next time!

A #SAYONARA_Ryugu message from Drs. Yonekura and Ryoki at the Usuda and Uchinoura Ground Stations: Thank you for showing us the images via Hayabusa2,we were able to talk a lot! Please don't forget about the 64m Usuda and 34m Uchinoura antennas whose power enabled all the talk.

Our “Goodbye Ryugu” Campaign #SAYONARA_Ryugu: We have been introducing messages from the Hayabusa2 Project staff, and the “Goodbye Ryugu” campaign will end today (11/19). Everyone, please send us a message! hayabusa2.jaxa.jp/en/topics/2019…

A message from our LIDAR team: With #SAYONARA_Ryugu we have established the LIDAR longest distance measurement record!! (At long distances, the distance measurement success rate drops rapidly (to about 1%) and the data is barely obtainable). pic.twitter.com/1ptBX3B5Iu

From Dr. Nittler (Carnegie) #SAYONARA_Ryugu: Good-bye Ryugu, thank you for welcoming our visit & putting up with our poking and prodding. I look forward to examining some of the small bits of you that are coming back to Earth to better understand your interesting history! Larry

I am excited to see what you have collected for us! I look forward to seeing your return to Earth and wish you a very safe trip home!! Gambari mashoka!! -- Paul Abell [3/3]

It has been an amazing experience to watch you during this terrific mission and share in the wonders that you have revealed to the world. Personally I am a little sad that you have to leave Ryugu now, but the samples that you carry back to Earth are very precious! [2/3]

We have a #SAYONARA_Ryugu message from Dr. Paul Abell at the NASA Johnson Space Center: Dear Hayabusa2, You have accomplished so much during your busy time at asteroid Ryugu! I can’t believe it is time for you to come home so soon! [1/3]

We received a #SAYONARA_Ryugu card from the @MASCOT2018team. The Hayabusa2 team was very lucky to work with the great members of MASCOT: thank you all very much! pic.twitter.com/yAEo0LdTJy

Maiko Yamakawa from Tsuda Laboratory says for #SAYONARA_Ryugu: I knew I would say goodbye. It felt natural that Hayabusa2 was at Ryugu. So it feels a little lonely now, but I look forward to seeing the souvenirs that you gave us. Goodbye and thank you, Ryugu. pic.twitter.com/Q4fvT1nrvm

Yuya Mimasu from Navigation Guidance Control sent this #SAYONARA_Ryugu: Thank you for the exciting days! It was an irreplaceable “out-of-the-ordinary” that lasted a year and a half that I will never forget.

#SAYONARA_Ryugu from Project Engineer Saeki: The preparations for Ryugu should have been perfect but the phrase “things seldom go as one wishes” hit home! There were so many things, but the activities on Ryugu made the team stronger. Good bye and thank you for the trouble!

Real-time delivery of our navigation images has now also ended. Thank you for watching! hayabusa2.jaxa.jp/en/galleries/o…

#SAYONARA_Ryugu message from Project Manager Tsuda: Now is the time to look ahead. We will look back no more. Our path is to Earth. We have taken the cruise attitude. Preparation for ion engine ignition. Thank you, Ryugu. Until the day we meet again.

And please tell the Little Prince, when he stops by, that we will someday visit his home, too. No Sayonara, but MATA AU HI MADE !! [3/3]

We realized that you were a giving star. So filled with love, that you even gave us a part of you body, just as Ampamman does so. Please pray for our safe way back. We will never forget you. (Ampamman = Japanese children’s character with a face made from a red bean pastry) [2/3]

Tomoyoshi Goda from NEC sent us this #SAYONARA_Ryugu message: Charming my fellow, You've been so great to us. At first, you looked so deathly. You pretended to be a real Death Star. But as we spent our time together, you became so kind. You've accepted our everything. [1/3]

A #SAYONARA_Ryugu message from Masahiko Hayakawa, responsible for SV: See you, Ryugu. Time with you has allowed me to grow & try many things. The way home seems busy, so we may forget you for a while. But in a year, your alter-ego will come to Earth. We will toast your portrait.

Today (Nov. 19) we changed to the spacecraft posture for ion engine operation. Attitude control was performed from 10:00 JST (on-board time) to 10:42 JST and confirmed by telemetry on the ground. Ryugu is no longer in the spacecraft camera. Goodbye, Ryugu, and thank you! pic.twitter.com/J5b0eJIbl2

We received a #SAYONARA_Ryugu postcard message from Stefania @RocketStefy(currently at the University of Liverpool, UK) who previously worked on calculating the trajectories for the project! pic.twitter.com/ScyueggS5P

Toru Yada, responsible for curation, sent the following #SAYONARA_Ryugu: To Ryugu, it is lonely to leave you but I am looking forward to seeing your fragments on Earth.

#SAYONARA_Ryugu from System Manager, Takei Yuto: There’s the expression “the ball is your friend” but for me, “Ryugu is your friend”. Because it is a NEA (Near-Earth Asteroid) and a member of the same Solar System, someday we can meet again. Until that day.

Our sub-manager, Satoru Nakazawa, writes for #SAYONARA_Ryugu: It was a year and a half too packed to remember every step. This is not the end. The mission is to safely deliver the capsule to Earth, collect it and bring is back. Let’s continue to strive to do our very best!

Patrick Michel sent a #SAYONARA_Ryugu from France: Good bye Ryugu, We are now looking forward to receiving little pieces of you in our labs, which will tell us what you are made of and about the Solar System history. And congratulations to Hayabusa2 for all the successes so far.

Science team member, Hikaru Yabuta, sent this #SAYONARA_Ryugu message: Thank you, Ryugu, for the happiness and excitement! You have been my focus for 10 years and it has been great. In one year. You’ll be on Earth.

This #SAYONARA_Ryugu message is from Project Scientist Sei-ichiro Watanabe: Beautiful Ryugu, thank you for deepening our technical and scientific understanding. I hope we can meet again someday. Until then, please take care of our parting gifts. Goodbye.

Hayabusa2 has achieved so much during its encounter with Ryugu, but the best is yet to come when the samples touch down in Australia next December! NASA is looking forward to collaboration on sample analysis and learning more about Ryugu!

We have also received a #SAYONARA_Ryugu message from Dr. Lori Glaze, Director of NASA's Science Mission Directorate’s Planetary Science Division, who wishes Hayabusa2 well on the journey back to Earth (next tweet):

HY2, it was the adventure of my life to leave Earth with you to Ryugu. Now it’s time to say goodbye & bring back the precious treasure as a witness of our journey. Please tell the people at home: When you look at the sky at night, I am here smiling at you. Safe trip back! -MASCOT

We received a message and photo from the @MASCOT2018team! pic.twitter.com/VM6ukwMyFJ
