Just thought I would start a similar topic as the 'VOYAGER chronology' ... of course with nice diagrams

With the passed 35th anniversary of Pioneer 10 Jupiter flyby ( 03 Dec 1973 ) it's time to look forward to the 30th anniversary of the Pioneer 11 Saturn flyby ( 01 Sep 1979 ) as illustrated here:

If I remember from reading an article years ago there was a proposal to fly Pioneer 11 through the Cassini Division of Saturn's rings as it was thought to be clear. Lucky they didn't because of course the Voyagers later found that it was by no means a clear division.
The historic Pioneer 10 flyby of Jupiter took place just over a year before I was born (and Pioneer 11 the month before) and for some reason in my mind the band Wings's song "Jet" seems to be a very appropriate number for the Pioneer 10 encounter.... Jet By Wings (1973) |

Here are two P10 images (A5 and A7) that I tried to correct for the planet's rotation and spacecraft motion. Still very rough, but I think that the relative positions of the cloud features are closer to reality, although there are still some scale issues.

Well, a side question to Pioneer chronology...
In SP-446, Pioneer -- First to Jupiter, Saturn and Beyond, at p.79 one reads: On November 7, Pioneer crossed the orbit of Sinope, the outermost satellite of Jupiter. In the following few days, the spacecraft successively crossed the orbits of Pan (renamed Carame) and Andrastea (renamed Ananke). By November 21, Pioneer 11 had crossed the orbit of Hera (renamed Elara) at just over 11.75 million kilometers (7 million miles) from Jupiter; it later crossed the orbits of Demeter (renamed Lysithea) and Hestia (renamed Himalia). So what are those forgotten names for the satellites of Jupiter, what is the history behind? And what is "Pan (renamed Carame)" in the context of the 1974 flyby of Jupiter? And another quote from 1973: Early in the encounter, Pioneer crossed the orbit of Hades, first of Jupiter's four outer moons; the following day, it crossed the orbit of Pan. On November 11, it crossed Amdrastea's orbit. On November 22, eleven days later, Pioneer will reach and cross the orbits of the three middle moons, Demeter, Hera, and Hestia, located 11.3 million kilometers from Jupiter. On December 3, the day of encounter, the spacecraft will make its closest approach to all five of Jupiter's inner moons. Which one of the outer satellites is not mentioned? |
