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.

Outstanding!
I have one thing about which I am curious. The final of the three images states it was taken while its rover was in mid-hop. I'm wondering why any hopping activity was occurring without any commands sent from Earth -- I didn't see any indication of pre-programmed hopping set up in the deployment and landing timelines that JAXA posted. And from the other statements made, both pre- and post-landing, I can't see any indication that hopping actions were commanded during this time. I *did* see something that indicated that the rovers were expected to "bounce" and take a good 15 minutes to settle down onto the surface in a stable, non-moving attitude. Could the caption which indicates the rover was hopping really indicate that it was in a bounce and not in a deliberate or commanded hop? The difference would be like stating that, say, Opportunity was "roving" as it bounced to a stop within Eagle Crater... -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
