Hayabusa 2 has started its descent towards Ryugu for Minerva deployment. Real time navigation images are posted here. One new image every half hour or so.

Thank you! Can't wait for more images! I wonder how long the rovers will last; perhaps when MASCOT lands too?

Thank you! Can't wait for more images! I wonder how long the rovers will last; perhaps when MASCOT lands too? I think somebody said something about rover hopping on this forum. I also have read something about it. Apparently, they are programmed to hop out of darkness automatically. So, they do one hopping each morning and if they fall into a shade they will automatically hop again. If they find themselves yet again in a shade, presumably they will hop again. If then again they land in a shade their battery power may be running out already and presumably they will die there, I think. They are perhaps like sunlight hoppers. P |

They are perhaps like sunlight hoppers. Prof. Takashi Kubota, the designer of previous MINERVA-I rover on Hayabusa 1, on request kindly sent me the paper he published as chapter 6 of book "Intelligence for Space Robotics", titled, "Intelligent Rover with Advanced Mobility for Minor Body Surface Exploration". I asked him: QUOTE Dear professor Kubota, I am following MINERVA-II-1 rovers operations on Ryugu, but I cannot find much technical data about them. Can you suggest any link or paper where I can read some details? I would like to figure out which mobility system they use w.r.t. MINERVA-I , and if they are remotely or autonomusly operated. Are the two rovers identical? and his answer is: QUOTE The mobility of MINERVA-II on Ryugu is the same as MINERVA. MINERVA-II can hop by an inner torquer (motor). MINERVA-II can explore Ryugu autonomously. Two rovers are almost identical. Takashi But he does not specify if he's talking about rovers 1a/1b or rover 2, so... who knows?!? I guess I'll have to ask again. I wrote to kubota dot takashi at jaxa dot jp but can't remember in which page/document I found this. He has other emails: https://www.abdn.ac.uk/ims/research/microbi...ofiles/t.kubota http://robotics.isas.jaxa.jp/kubota_lab/en/people.html |
