Triton Moon Regenerating Surface
Triton, the large frozen moon of Neptune, has surface that apparently undergoes regeneration as do Jupiter’s moons Europa and Io, Voyager 2 scientists said. In paper prepared for presentation before the 1989 Fall Meeting of the American Geophysical Union in San Francisco, Dec. 4, scientists who analyzed Photopolarimeter (PPS) instrument data discussed three of Neptune’s […]
Voyager’s Science Papers Presented at American Geophysical Union
Science papers and poster presentations on Voyager’s encounter with Neptune were scheduled Dec. 4-5, the first two days of the 5-day 1989 Fall Meeting of the American Geophysical Union at San Francisco. Members of the Voyager science teams from various institutions in addition to NASA’s Jet Propulsion Laboratory, have been analyzing Voyager 2 data since […]
Voyager 2 Detects Intense Radio Emissions
NASA’s Voyager 2 spacecraft has detected intense radio emissions from Neptune, indicating that the planet has magnetic field. The discovery, made by Voyager 2’s planetary radio astronomy instrument team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., greatly increases the likelihood that the spacecraft will discover wide range of interesting phenomena related to magnetic field, such […]
Voyager 2 Enters Final Planetary Encounter
NASA’s Voyager 2 spacecraft today entered the observatory phase of its flyby of Neptune, signaling the beginning of its final planetary encounter after nearly 12 years of exploring the outer solar system. Voyager mission controllers at the Jet Propulsion Laboratory in Pasadena, Calif., will now be tracking the spacecraft around the clock as Voyager begins […]
Voyager Celebrates Its 10th Anniversary
With one of its two spacecraft en route to distant Neptune and the other exploring the outer solar system, the Voyager Mission celebrates its 10th anniversary of launch on Aug. 20. Voyagers 1 and 2, launched by NASA in August and September 1977, have logged billions of miles over the past decade executing flybys of […]
NASA Voyagers Provides Precise Measurement of New Cosmic Ray Particles
NASA’s two Voyager spacecraft, exploring different areas of the solar system more than two billion miles from Earth, have provided the most precise measurements yet of new species of cosmic ray particles, Voyager project scientist Dr. Edward Stone said. Dr. Alan Cummings, Caltech physicist who worked with Stone in studying the particles, presented the Voyager […]
Voyager Project Wins the Nelson P. Jackson Aerospace Award
For the second time in its 10-year history, the Voyager Project at the Jet Propulsion Laboratory, Pasadena, Calif., has been named the winner of the Nelson P. Jackson Aerospace Award by the National Space Club. The award honors the engineering expertise that resulted in the Voyager spacecraft missions to Jupiter, Saturn and Uranus. Former Voyager […]
NASA Highest Honors Awarded to Voyager Teams
NASA’s highest honors were awarded in ceremony today at JPL to more than 70 indivduals and teams for their professional contributions to the successful Voyager spacecraft mission to Uranus. The Voyager 1 and 2 spacecraft, designed, constructed and operated by JPL, were launched in 1977 and flew past Jupiter in 1979 and Saturn in 1980 […]
Voyager 2 Prepares for 1989 Neptune Flyby
NASA’s Voyager 2, departing from its Jan. 24 encounter with Uranus, has undergone major course correction to prepare the spacecraft for its 1989 flyby of the planet Neptune. Voyager Project members at JPL sent commands instructing the spacecraft to fire its hydrazine thrusters for 2 hours and 33 minutes on Feb. 14. The maneuver will […]
Six Additional Uranus Moons Found
NASA’s Voyager 2 spacecraft has found six additional small moons in orbit around the planet Uranus, doubling the number of Uranian satellites known. Scientists on the Voyager imaging team found the moons in long-exposure images returned by the spacecraft over the past two weeks. The exposures were designed to search for new moons or rings. […]
