Aug 22, 2019 · Credits: NASA/JPL-Caltech. Thirty years ago, on Aug. 25, 1989, NASA’s Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system’s eighth planet. Marking the end of the Voyager mission’s Grand Tour of the solar system’s four giant planets — Jupiter, Saturn, Uranus and Neptune — that ...

Aug 25, 2014 · This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken on Aug. 20, 1989, at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach on Aug. 25. The picture shows the Great Dark Spot and its ...
Aug 26, 2019 · In the summer of 1989, NASA’s Voyager 2 became the first spacecraft to fly by Neptune, its final planetary encounter. Managed by the Jet Propulsion Laboratory in Pasadena, California, Voyagers 1 and 2 were a pair of spacecraft launched in 1977 to explore the outer planets. Initially targeted only to visit Jupiter and Saturn, Voyager 2 took ...

Thirty-five years ago, on August 25, 1989, NASA’s Voyager 2 spacecraft made a close flyby of Neptune. It gave humanity its 1st close-up of our solar system’s 8th planet. It also marked the end of the Voyager mission’s Grand Tour of the solar system’s 4 giant planets, Jupiter, Saturn, Uranus and Neptune. No other spacecraft has visited Neptune since...
During the encounter, the engineering team carefully changed the probe’s direction and speed so that it could do a close flyby of the planet’s largest moon, Triton. The flyby showed evidence of geologically young surfaces and active geysers spewing material skyward. This indicated that Triton was not simply a solid ball of ice even though it had th...
The conclusion of the Neptune flyby marked the beginning of the Voyager Interstellar Mission. Forty-seven years after launch, Voyager 2 and its twin, Voyager 1 (which had also flown by Jupiter and Saturn), continue to send back dispatchesfrom the outer reaches of our solar system. At the time of the Neptune encounter, Voyager 2 was about 2.9 billio...
By the time Voyager 2 reached Neptune, the Voyager mission team had completed five planetary encounters. But the big blue planet still posed unique challenges. Neptune is about 30 times farther from the sun than Earth. So, the icy giant receives only about 0.001 times the amount of sunlight that Earth does. In such low light, Voyager 2’s camera req...
The probe’s distance meant by the time radio signals from Voyager 2 reached Earth, they were weaker than other flybys. But the spacecraft had the advantage of time. The Voyagers communicate with Earth via the Deep Space Network, or DSN, which utilizes several radio antennas. They are in Madrid, Spain; Canberra, Australia; and Goldstone, California....
In the week leading up to that August 1989 close encounter, the atmosphere was electric at NASA’s Jet Propulsion Laboratory in Pasadena, California, which manages the Voyager mission. As images taken by Voyager 2 during its Neptune approach made the four-hour journey to Earth, Voyager team members would crowd around computer monitors around the Lab...
Of course, the Voyagers’ achievements extend far beyond that historic week over three decades ago. Both probes have now entered interstellar space after exiting the heliosphere, the protective bubble around the planets created by a high-speed flow of particles and magnetic fields spewed outward by our sun. They are reporting back to Earth on the “w...
Aug 25, 2024 · On Aug. 25, 1989, NASA's Voyager 2 spacecraft took the first-ever close-up images of Neptune. This one — among the last full-disk photos taken before the probe ended its "Grand Tour" of the ...

Aug 22, 2019 · A massive, slate-colored storm was dubbed the "Great Dark Spot," similar to Jupiter's Great Red Spot. Six new moons and four rings were discovered. Voyager 2 took these two images of the rings of Neptune on Aug. 26, 1989, just after the probe's closest approach to the planet.
