Podcast Advisory May 23, 2006
Voyager: Still Going Strong After Nearly 30 Years NASA's twin Voyager spacecraft are beaming back new information about the final frontier of our solar system, including evidence of "potholes" in the turbulent zone near the edge. A podcast, featuring an interview with Voyager Project Scientist Dr. Ed Stone of Caltech, is online at http://www.jpl.nasa.gov/multimedia/podcast/voyager-20060523/ . The interview includes information about the latest findings, as well as highlights from the past 29 years of the Voyagers' journeys through space. More information on the Voyager spacecraft is available at http://voyager.jpl.nasa.gov/ and www.nasa.gov/voyager . Voyager 1 and 2 launched in 1977 on a mission to study the outer planets of our solar system, and they are now on their way to becoming the first spacecraft to leave our solar system. Additional JPL podcasts are at http://www.jpl.nasa.gov/multimedia/indexPod.cfm . -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Climber, Pioneer didn't reached the heliopause because they are slower.
This is clear looking to distances from Sun, calculated by Solar System Simulator and ranked in descending order: Voyager-1: 99.2 AU Pioneer-10: 90.6 AU Voyager-2: 79.7 AU Pioneer-11: 69.9 AU (hey, they are almost equally spaced in this moment!) In particular, Pioneer-10 was surpassed by Voyager-1 several years ago and, anyway, now is inactive... Thanks, ljk4-1 for the interview highlight. The words of Dr. Ed Stone confirm that Voyager entered in a new region as I suspected, but still to reach the heliopause which should be 5 AU ahead! -------------------- I always think before posting! - Marco -
