Volcanic activity was discovered by Voyager 1. If you want to showcase Voyager 2, say that it took the first close-up views of Europa's active, ice-covered surface. The thing with Voyager 2 is that it captured an image of an active volcanic eruption. Voyager 1 discovered evidence of volcanic activity, but not an eruption in progress. Sure it did: beacon.jpl.nasa.gov/exhibits/voyager/Jupiter/photo5.htmlIn fact, the first plume was identified when Linda Morabito enhanced an image of Io to check navigation. The enhancement revealed what looked like a spherical moon beyond Io. Quick checking revealed that no such moon should have been in the frame. Just a couple of weeks before, an article in Science predicted volcanic activity at Io. The Voyager imaging team quickly realized that they were looking at a volcanic plume directly over the feature they called Loki. They identified a second plume on the terminator (they thought it was a peak until they worked out that it would have been several dozen miles high). Enhancing other photographs revealed more plumes, such as the one linked above. Active volcanoes and their plumes were definitely Voyager 1 discoveries.

Obviously the source I read was wrong.

I really enjoyed reading that Morabito memoir. So many people misunderstand science and scientists. They are shunned by the "popular" folks, and Hollywood portrays them as antisocial loners. What they don't get is that science is fun! Read her description of the discovery again: One of my favorite episodes of From the Earth to the Moon was "Galileo was Right", which described how Dr. Lee Silver and others converted a bunch of jet-jocks into enthusiastic geologists. I just love listening to the results.

That's one of my favorites as well. I changed the Voyager 1 and 2 stuff on my page. I added a note to Voyager 1 about Io and changed the note for Voyager 2 to one about Europa.

[hippy voice]Oh wow, tune in to my buddy Europa, man. Tell everyone what a "groovy" place it is. . . [/hippy voice]

Alan Shepard as the US's first person into space. Robert M. White as first X-15 pilot into space Mike Melvill as first Private spacecrat Pilot into Space Gene Cernan Last man to set foot on the moon. With a couple possible exceptions, I don’t want to add any more astronaut portraits. I’ve already honored those who are arguably the most famous – Gagarin, Glenn and Armstrong. If I decide to feature any additional astronaut/cosmonaut accomplishments, I’ll likely do so with an action shot from one of their missions, like I’ve already done with Alan Shepard. One of the exceptions is that I’d like to honor women in space. I’ll probably do so with a photo of Eileen Collins, whose firsts I think outshine either Valentina Tereshkova or Sally Ride. Christa McAuliffe as first civilian to fly in the space shuttle and a dedication to the Challenger's final Crew. I might do something with Challenger, but as far as a portrait goes, I thought I might include one of Vladimir Komarov as a symbol for all who have died. Komarov was the first to die on a space mission and I find his story particularly heart-wrenching. I also don’t want to load up on too many Americans. Dr. William H. Pickering Director of JPL during then Space Race. Pickering might be a good addition. I’ll have to study up on his career a bit.

Gene Cernan Last man to set foot on the moon. Harrison Schmitt was the last man to walk (or "set foot") on the moon. Cernan was the man who last walked on the moon.
