I just heard that Odyssey went into safe mode on Saturday. I haven't seen any official announcement yet.
One result is that MER is having to replan using direct to earth only. Current estimate is that Odyssey will not be able to support UHF relay until "mid-week at the earliest". |

Just a quick mention, with regards to the importance of Odyssey's use as a relay.
MGS did support some relay operations early on in the mission, but it appears that it is unable to do so right now. MGS status report Back on July 21, 2004 in the above status report: QUOTE MGS will finish its UHF relay support for both rovers tonight (local) at the beginning of the UTC day 04-204 (7/22/04) when it enters the Beta-Supplement mode of operations. MGS enters this mode of operation whenever the Earth Beta Angle decreases to less than 43 degrees in order to avoid the HGA obstruction discovered in April 1999. And, as of the last update, it is still in Beta-Supplement mode. So, if Odyssey can't downlink data to Earth, they lost the primary and at this point only alternative to DTE transmission from the rovers of images/data. Lets hope this gets fixed soon, this would be a huge blow to the revitalized rovers. |
