It seems to be a season of anniversaries over the next year or so.
20 years since Voyager 2 at Neptune (see my posting there), 30 yrs since Voyager 1 at Io, 30 since Voyager 2 at Europa, 30 years since VEJUR at . . . . well never mind! plus all the Galileo 400th commemorations (I will have more on that next week). I thought it would be a good time to start a thread on this one, which occurred on a tuesday morning in July 1979. Although the images had been taken on July 9, they were recorded for playback the next day. I was a mere summer intern in those days and was attending the morning briefing along with the rest of the Sci Support Team of which i was a member. Linda Horn and Ellis Miner were my gurus that wonderful summer. Playback was scheduled for sometime between 8 and 9, as i recall, and I can still remember looking up at the monitor as the first high resolution images ever seen of Europa first appeared. Wonderful, even tho only 2 kilometers in resolution. Little did I know where it would lead me . . . Here is a restored version of one of the two mosaics returned that day. They hint at some of the exotic things that Galileo later discovered. cheers paul -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

Indeed the scientific community had to wait for the "Millennium flyby" of Jupiter to get great images of Europa. Resolution in the Voyagers' images was too poor and no features were named on this icy moon. However, three new feature terms were adopted:
Flexus = cuspate linear features Linea = straight lines Macula = circular dark areas Post Scriptum: shouldn't this be moved to the Pioneer/Voyager subforum It fits in just fine here. |
