I wonder if anybody has a Voyager chronology with such details as dates of all TCMs or precise times of closest approach to different moons of Jupiter back in 1979. What I've found of pre-Saturn TCMs is here:
Voyager 1 1977.09.05 Launch 1977.09.11 TCM-1 1977.09.13 TCM-1 1977.10.29 TCM-1A 1978.06? TCM-2? 1979.01.04 Jupiter Observatory Phase 1979.01.29? TCM-3 1979.02.21 TCM-4 1979.03.05 Jupiter Flyby 1979.04.09 TCM-5 ... 1980.08.22 Saturn Observatory Phase 1980.10.10-11 TCM A8 1980.11.06 TCM A9 1980.11.12 Saturn Flyby Voyager 2 1977.08.20 Launch 1977.10.11 TCM-1 1978.05.03 TCM-2 1979.04.24 Jupiter Observatory Phase 1979.06.27 TCM? 1979.07.09 Jupiter Flyby 1979.07.09 TCM? 1979.07.23 TCM? 1980? TCM B6? 1981.02.26 TCM B7 1981.06.05 Saturn Observatory Phase 1981.07.19 TCM B8 1981.08.18 TCM B9 1981.08.26 Saturn Flyby |

So the official NASA extended mission plan for Voyager 1, last updated in June 2014, tells us that this is the year its gyroscope will be shut down: "Discontinue gyro operations (+14.4 W steady state, +3.6 W turn on transient and maneuver) - 2015; TBD. This power load reduction step is currently sequenced to occur on DOY 350, 2015 but could be changed if the RTG output is better than predicted."
I assume DOY 350 would be ooa December 16, 2015... Okay, so does anyone know anything more? Is the RTG output about as expected? And what consequences will there be from turning off the gyroscope? Doug M. |
