Anyone know the latest Voyager status? I've hear rumors, but I'm wondering if anyone has anything more concrete (I won't share the rumors, as I really don't know much about it, so...)

During my recent explorations into the bowels of Nasa's web servers, I came across this recent mishap of Voyager 2:
QUOTE Notes on Voyager 2 Quick Look Data: Data after Nov 29, 2006 On November 30, 2006, a spacecraft systems command was incorrectly decoded by the spacecraft as a command to turn on the heaters associated with the mechanical flipper mechanism for the outboard magnetometer on Voyager 2. The heaters on remained until Dec 4, 2006, resulting in extremely high temperatures (> 130C). The sensors rotated away from the orientation in which they were designed to operate, and the characteristics of the instrument were changed in ways that are not yet fully understood. The result is seen in the quick look data as extremely high magnetic fields. It has not been possible to fully diagnose and correct for the damage to the Voyager 2 magnetometer, although efforts to do so are ongoing. Data from the spacecraft roll scheduled for March 15, 2007 and special coil orientations before and after, will provide crucial information needed to design a process to recover scientific data from the modified instrument. ftp://vgrmag.gsfc.nasa.gov/pub/voyager/quicklook/v2-warning Since I couldn't find any info about it on this forum nor any news anywhere else, I'd like to see if anyone knows a bit more what the heck happened there and whether the magnetometer was successfully recharacterized after the recent roll. Also, did this have any long term impact to the health of the spacecraft? |

Since I couldn't find any info about it on this forum nor any news anywhere else, I'd like to see if anyone knows a bit more what the heck happened there and whether the magnetometer was successfully recharacterized after the recent roll. Also, did this have any long term impact to the health of the spacecraft? The reason for this is the HYBIC swap test. The test itself has been successful, but it changed the status of the MAG and turned on IRIS (turned off since then). The permanent HYBIC swap is on hold because of this. I have no information about the MAG status. I also do not know if all four MAG instruments are involved or not. Analyst |
