Excellent Performance in the Touchdown 2 Operation of Hayabusa-2. Congratulations to all involved in JAXA / ISAS. It was great to see this live !

Nicely managed impact, and happy to know that H2 is safe. From the picture it appears that the impact was in the high latitudes. If a landslide occurs at these latitudes, in which direction does the flow happen, towards the pole or the equator? If a decent sized crater is made, is it expected that the exhumed material will have a noticeably different colour, perhaps less dark than the remaining surface? Another question, unconnected with the impact: do spectral data reveal that Otohime Saxum (hope I got the spelling right) has different compounds in its composition from the rest of the surface?

Congratulations on the touchdown, it seems it went off perfectly even if the target area was small.
Do we have some results from spectrometry on Hayabusa2 about composition of Ryugu?

lodayaOct. 6, 2018 01:18Reply

Events are happening really fast on Ryugu! Congratulations.
Next we have the second sampling rehearsal.
I understand part of the rush is because Ryugu will be going behind the Sun next month.
I guess you would want to maximize the experiments completed by then.
Since Hayabusa2 will be invisible to us then, will it autonomously maintain the 20 km home position?
Are any observations planned then which will be relayed to Earth when communication resumes after several months?
Or does Hayabusa2 just maintain an uneventful watching brief until it comes back into our line of sight?

Nur wer kleine Dinge zu schätzen weiß, wird große Dinge erkennen.
Ein kleiner Asteroid im All, eine großartige Leistung für Wissenschaft.

Nachdem die MASCOT-Landung erfolgreich ablief, kann man als Fan dieser Mission nur hoffen das die 16 Stunden betriebsfähigkeit von Mascot alle erhofften Resultate für die beteiligten Wissenschaftler bringen. Es wird ja bald nochmal sehr spannend, wenn der Mechanismus der Probenaufnahme bei Hayabusa-2 erfolgreich ist und der Rückkehrbehälter seinen Weg zur Erde findet. Wir freuen uns darauf ! Gratulation und Danke an die beteiligten Teams von JAXA; DLR und CENES.

Many thanks to JAXA and Hayabusa-2 team for the impressive, fascinating pictures of the Minerva-Rover 1A and B. Interesting pictures from the far distance of space for the people on Earth. Impressive miniaturized camera technology Made in Japan! Congratulationsfor these spectacular successes of Micha. I hop for more new scientific findings from Hayabusa - 2 !

Hey, I have just heard that your two Hopping Rovers successfully touched the surface!! Very cool, and fascinating, you guys are awesome!!
CONGRATS JAXA, you have given mankind another leap!!

Cheers from Philae, if it were alive, it would surely be cheering. From the bounces, what kind of hardness and temperature information are we getting? Is the surface of Ryugu as hard as that of 67p? Is the second hopper still transmitting from a stationary position? Please do tell us how often data is sent to Hayabusa2 and whether it is in order or has to be aggregated.

lodayaSep. 19, 2018 21:38Reply

The Minerva hoppers seem to be very interesting, with an unparalleled level of autonomous control, that too on the surface of a small body. Looking forward to a completely new perspective on Ryugu.

lodayaAug. 11, 2018 02:47Reply

Since the free fall went further than expected, is Ryugu less dense than expected?
Finding a landing place looks tough, it looks like the maneuverability capabilities of the landers are going to come in handy.
Best wishes.

"Who has been eating my dango?" asked Goldilocks.

Seriously, this is an astonishing find! Can a strike like this result in retrograde rotation?

Congratulations on reaching Ryugu! My two grandson's names are on your Hayabusa-2 spacecraft. Will their names be dropped off to remain on Ryugu, or return to Earth after their journey? Thanks for giving my grandsons a great introduction to space exploration, and a lot of excitement!

Michael Broemmerreply for Hal Lane - NC, USAJul. 15, 2018 17:59Reply

Hello Hal Lane , on the spacecraft Hayabusa-2 there are two memory chips. A name chip is attached to one of the target markers, wich is discarded and remains on the asteroid Ryugu. The other chip with names and messages is located in the spacecraft`s return container. This lands back to Earth at the end of 2020 with material samples from the asteroid at Woomera / Australia. Many greetings from Michael.

Michael BroemmerJun. 27, 2018 10:43Reply

We are there ! Congratulations on reaching the home station. Now it will be an exciting time, greetings from Michael and his friends from Germany !

lodayaJun. 25, 2018 22:15Reply

I learnt that like Hayabusa1 did for Itokawa, Hayabusa2 will not be in a gravitationally bound orbit of Ryugu but will maintain a parallel heliocentric orbit on its own propulsion.

lodayaJun. 24, 2018 21:05Reply

On 27th or thereabouts does Hayabusa2 go into orbit around Ryugu? If so, would that be the smallest body around which a spacecraft has been in a bound orbit? I tried looking up information on Hayabusa1 and it does not appear to be the case that it was in orbit around Itokawa.

What is the albedo of the bright feature on the pole of Ryugu?

Michael Broemmerreply for lodayaJun. 26, 2018 02:23Reply

Maybe a diffused surface like ice, metallic matter or something similar ? Greetings from Michael.

lodayareply for Michael BroemmerJun. 26, 2018 14:36Reply

Greetings from India, Michael, and thanks for writing back. Hydrated minerals were suggested from Earth-based spectra, better spectral data should soon be available from the spacecraft. From the all-round views, the feature suggests a cliff where the surface has fallen off to expose inner material. Perhaps some of the craters could also be caused by flow of surface material towards the equator rather than by impact.

lodayaJun. 14, 2018 20:39Reply

Congratulations and we are eagerly awaiting better pictures of the "dango" shape. Can Hayabusa2 detect whether Ryugu is rotating?

Michael BroemmerJun. 5, 2018 17:30Reply

Congratulations to the team for ending the forward drive engine operation at Hayabusa - 2. Continue to good luck for the final approach phase at Ryugu. Now it will be very exciting ! Greetings Michael and his friends from Germany.

Hayabusa - 2 with Lander Mascot sets for the final sprint. All the best for the last 50000 km and a good arrival at the finish - asteroids Ryugu wish Michael and his friends from Germany !

Che scoperte, che avventure ci aspettano con Hayabusa2!!
Oltre i cieli dell’avventura viaggia senza paura, come un raggio che ha il coraggio di lasciare il sole dietro se,
per una missione eccezionale sulle strade della scienza.
Tu sai chi vedrai laggiù, più in là del cielo blu, vai e non fermarti mai finché non troverai.
Allacciamo le cinture, viaggiando s'impara!!

Hayabusa2's so nearest fly-by of the Earth is one of the best beautiful journey ! Best wishes from Seoul.
(Although I'm not an astronomist nor a physicist, I sometimes dream to land on Ryugu asteroid with Hayabusa II. I'm a pediatrician, that's why I dream like a baby?)

Hi their guys. This is Andre from Jeffreys Bay in South Africa.When i was a young guy I always thought about space as an unreachable mysterious place.You guys are in the process of changing that thoughts of mine as a young guy about space to something that is within the reach of us as earthly humans and a place of emense interest,
Thanks for your emense effort and I shall be following your progress with great interest.
