Thanks Doug for that link. Look at this pdf on that same site:
http://mgsw3.jpl.nasa.gov/seq/M1O/SOE/cs054d.00.rsoe.pdf 05-095/21:39:47.3 (GMT): SAFEMODE_EXIT : Transitions the spacecraft to nominal mode if not already in nominal mode. and then apparently deletes the recovery sequence: 05-095/23:50:47.9 (GMT): Deletes the designated file.: d:/seq/map_sm_recovery_upgo.rel So, maybe Odyssey is recovering... |

Well - we were told Wednesday Maybe tonights UHF passes will be nominal - and I imagine they will use every single UHF opportunity there is for the next few sols, even the poor ones, to get as much back as possible.

Twenty new navcams were added at exploratorium 15 minutes ago, a good sign?

Yes, they are out of safe mode, and had their first chance for a relay from Spirit at about 4:45 PM local time. Looks like it was successful! Good news. I never did hear what caused the safe mode. |

QUOTE (djellison @ Apr 6 2005, 05:14 AM) If anyone wants to poke around somewhere they probably shouldnt be... http://mgsw3.jpl.nasa.gov/seq/odyseq.html there might be something in there somewhere ... Doug Thanks for that link.... real interesting stuff there. I looked into the Radiation Log and found the frequency of command files sent to Odyssey each day this year. There was an especially interesting label of "FSW_OBJ_INITIAL". I created a little graph of files radiated by day... with the "Red" portion of the bars indiciating those INIT files. Seems like a lot of activity in the last few days to get out of safe mode with a lot of those INIT command files. Glad to hear things might be fixed! |

Finally an "official" story from NASA about all this, not on the Mars Odyssey page of course but in the Spirit status report for April 8:
(Sol 446 is April 5, 2005) "Sol 446: Spirit and Opportunity use NASA's Mars Odyssey orbiter as their main communications link between Mars and Earth. On April 2, Odyssey entered "safe mode," which is a protective state a spacecraft automatically enters when onboard fault protection software instructs the spacecraft to disregard its onboard sequence of commands and wait for instructions from the ground. As a result, relay communication with the rovers was suspended, and Spirit did not receive any data from sols 444 and 445. With an unknown status of the rover after its drive, the Spirit team restricted rover operations to remote sensing. Sol 447: The Odyssey flight team scrambled to recover the orbiter, but it remained in a safe state, not yet available to support relay communications. Spirit received very little information from its "direct-to-earth" communications link, so the rover team planned another basic remote sensing sol, which generated little data. Sol 448 (April 7, 2005): Spirit performed additional remote sensing, including panoramic camera and navigation camera imaging. The Odyssey team brought the orbiter back on-line, the Spirit team received all imaging needed for continuing to drive, and team members are planning to drive on sol 449 with a new appreciation for their orbiting partner! The Odyssey team is investigating the cause behind the fault protection software sending the orbiter into safe mode." http://marsrovers.jpl.nasa.gov/mission/status.html Note there is no mention of the Odyssey safing in the earlier status reports for April 2, 3 or 4 -------------------- |

Either they didnt drive or the drive stalled as Spirit didnt move on Sol 449, maybe slippage again?
