QUOTE (Kei-ichiro Sakurai @ Nov 26 2005, 12:05 AM) The doppler signal was disturbed at the moment of touchdown, which was not expected for a 'smooth' touchdown, Kawaguchi says.  Sorry this was Matogawa's words, I'm also gettin' sleepy :P One more translation from Matsuura's blog: Journalist, watching the streaming: 'Hmm, Prof.Kawaguchi is laughing?' Prof. Matogawa: 'I guess he just don't have any other things to do for the moment.' :D |

The smatsu's blog has some quotes from Prof. Matogawa, ISAS:
""" We don't have any information as of yet, because we only have the doppler data. We are in the process of switching the communication over to Usudat station, so we'll know the status once we establish the downlink from there. If it indeed landed in Muses Sea, the doppler sample would have been smooth, but the fact is that we lost it for a moment. We don't know why yet. But if it drifted over to a rocky area, this (the loss of beacon signal) is quite possible. When we decided that it was at the altitude of 22m, one of the beam was reading 17m and the other was reading 30 something meters, thus it is possible that it drifted towards a sloped area. There is this rocky area we call "Yatsuga-take", approximately 60 meters away from the planned landing site, so this is quite possible. We should have a downlink established via Usuda station around 8:10am JST. We just have to wait until then. The guys in the operation room are simply waiting, as there is nothing we can tell at this point. When we learned of the ascent, Project Manager Kawaguchi said "let's give it another shot". The staff members were a bit surprised at his comment, but he is 100% in this right now. """ This was from 7:55am entry. |

"Now we are switching the antenna from DSN (Deep Space Network) into ISAS Usuda Deep Space Center."

What might it affect this kind of signal disorder? :blink: Rodolfo From Matsuura's 07:38 entry I judge it doesn't mean 'a strange doppler shift', but a discontinuance of the signal itself for 5-6 minutes. Oh-uh, now people are gathering with their arms crossed...? |

Now, thru the live TV, the command room is getting even more crowded. There might be some important announcement....
