PROGRAMS WILL SHARE EXCITEMENT OF VOYAGER DISCOVERIES
Two free public programs in Pasadena next week will present highlights
of the scientific bonanza from NASA's twin Voyager spacecraft, launched 25
years ago and still going strong in one of human history's greatest missions of
exploration.
Dr. Edward Stone, Voyager project scientist since 1972, will show
pictures and explain discoveries from the mission on Thursday evening, Sept. 5,
at NASA's Jet Propulsion Laboratory and on Friday evening, Sept. 6, at
Pasadena City College.
Voyager 1, launched Sept. 5, 1977, visited Jupiter and Saturn and then
angled northward. It is now the most distant human-made object. Voyager 2
also examined Jupiter and Saturn and then became the only spacecraft to visit
Uranus and Neptune. Besides those four planets, the twin spacecraft observed
48 moons. They discovered active volcanoes on Jupiter's Io, thick haze on
Saturn's Titan, towering cliffs on Uranus' Miranda and geysers on Neptune's
frigid Triton.
"Everywhere we went, we found surprises," Stone said. "Over and over
we saw that nature is incredibly inventive." The two spacecraft still radio home
information almost every day about the outer reaches of the solar wind --
ionized atoms flung outward by the Sun. Scientists hope Voyager 1 will pass
beyond the solar wind into true interstellar space before its nuclear power
supply runs too low for the spacecraft to tell us about the environment
surrounding it, about 20 years from now.
Stone, the David Morrisroe Professor of Physics at the California
Institute of Technology, was JPL's director from 1991 to 2001. He has been a
principal investigator or co-investigator on 14 NASA missions. Caltech
manages JPL for NASA.
Both of his lectures will begin at 7 p.m. Seating is first-come, first-
served. The Thursday lecture will be in JPL's von Karman Auditorium. JPL is at
4800 Oak Grove Dr., off the Oak Grove Drive exit of the 210 (Foothill)
Freeway. The Friday lecture will be in Pasadena City College's Vosloh Forum,
1570 E. Colorado Blvd. For more information, call (818) 354-0112. Thursday's
lecture will be webcast live and available afterwards at
