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 |

I can offer the following, need to do more research to verify timezones and SCET/ERT:
The Overtaking: 19 Dec 1977 Voyager 1 overtakes Voyager 2 Voyager 1 05 Mar 1979 (06:54) Amalthea: Amalthea flyby (distant) 05 Mar 1979 (12:05) Jupiter: Jupiter Fly-By 05 Mar 1979 (15:14) Io: Io flyby 05 Mar 1979 (18:19) Europa: Europa flyby (distant) 06 Mar 1979 (02:15) Ganymede: Ganymede flyby 06 Mar 1979 (17:08) Callisto: Callisto flyby 12 Nov 1980 (05:41) Titan: Titan flyby (targetted) 12 Nov 1980 (22:17) Tethys: Tethys flyby (distant) 12 Nov 1980 (23:46) Saturn: Saturn Fly-By 13 Nov 1980 (01:43) Mimas: Mimas flyby 13 Nov 1980 (01:51) Enceladus: Enceladus flyby (distant) 13 Nov 1980 (03:39) Dione: Dione flyby (distant) 13 Nov 1980 (06:22) Rhea: Rhea flyby 13 Nov 1980 (16:45) Hyperion: Hyperion flyby (distant) 17 Feb 1998 Voyager 1 overtakes Pioneer 10 and becomes most distant spacecraft from the sun by 2028 Reaches Heliopause in 40,000 years Passes Star AC+79 3888 (at distance of 1.6 light-years) Voyager 2 08 Jul 1979 (12:21) 214,930 km Callisto: Callisto flyby (distant) 09 Jul 1979 (07:14) 62,130 km Ganymede: Ganymede flyby 09 Jul 1979 (17:53) 205,720 km Europa: Europa flyby (distant) 09 Jul 1979 (20:01) 558,370 km Amalthea: Amalthea flyby (distant) 09 Jul 1979 (22:29) 721,883 km Jupiter: Jupiter 09 Jul 1979 (23:17) 1,129,900 km Io: Io flyby (distant) 25 Aug 1981 (09:24) 665,960 km Titan: Titan flyby (distant) 26 Aug 1981 (01:04) 502,250 km Dione: Dione flyby (distant) 26 Aug 1981 (02:34) 309,990 km Mimas: Mimas flyby (distant) 26 Aug 1981 (03:24) 161,081 km Saturn: Saturn 26 Aug 1981 (03:45) 87,140 km Enceladus: Enceladus flyby 26 Aug 1981 (06:12) 93,000 km Tethys: Tethys flyby 26 Aug 1981 (06:29) 645,280 km Rhea: Rhea flyby (distant) 24 Jan 1986 (17:59) 107,092 km Uranus: Uranus 14 Feb 1986 2.5 hrs trajectory correction maneuvre targets Voyager 2 towards Neptune 25 Aug 1989 39,800 km Triton: Triton 25 Aug 1989 (03:56) 29,216 km Neptune: Neptune by 2008 Termination shock area by 2028 Reaches Heliopause in 296,000 years Passes Sirius (at a distance of 4.3 lightyears ) -------------------- |

Voyager 2 25 Aug 1981 (09:24) 665,960 km Titan: Titan flyby (distant) 26 Aug 1981 (01:04) 502,250 km Dione: Dione flyby (distant) 26 Aug 1981 (02:34) 309,990 km Mimas: Mimas flyby (distant) 26 Aug 1981 (03:24) 161,081 km Saturn: Saturn 26 Aug 1981 (03:45) 87,140 km Enceladus: Enceladus flyby 26 Aug 1981 (06:12) 93,000 km Tethys: Tethys flyby 26 Aug 1981 (06:29) 645,280 km Rhea: Rhea flyby (distant) Again I was able to extract Voyager 2 Saturn visit times from the article by Campbell, Jacobson et al.

Two or more lines for rings crossing were not discernible. 2. Numbers cross-checked against the Saturn CA time. 3. Current names an designations for small satellite discovered in 1979-1980 are used. 4. Don't know why this distance to Phoebe was there in the table. 5. Current estimate for Saturn CA seems to be 03:24:05. |
