Forgive the quality of the pictures but the only ones I could find were just thumb nails and I had to enlarge them a lot just to get to this size. This next picture shows what one of the space craft looks like. (You can't call them satellites because they don't orbit anything.")
In this last picture, it shows the two spacecraft at the edge of our helio system and about to enter the "bow shock" area where the interstellar winds equal the solar winds. A boundary that no craft from Earth has ever passed before.
Sorry about the quality of the pictures and the fact that it is hard to make out the nomenclature.
Now for the top ten things that they discovered and/or studied in more depth and clarity than ever before.
1. Volcanoes on Jupiter's moon Io.
2. Jupiter's turbulent atmosphere.
3. An ocean within Europa?
4. The Io torus.
5. Saturns' ring structure.
6. Titan's atmosphere.
7. Neptune's Great Dark Spot.
8. Neptune's supersonic winds.
9. Geysers on Triton.
and 10. The edge of the solar system.
Most of this information seems old to us now, but remember these crafts were launched back in 1977 and did make wondrous new discoveries. If any of you would like any additional information about any of the above, you can ask me and I will tell you, if I know the answer. And if any of you are planning that long of a trip, I hope you have a really, really big suitcase!! So, better stay on Earth and have a very nice day, you hear?
