Voyager-2 passed Uranus

January 24, 1986, spacecraft Voyager-2 NASA flew by Uranus. This was the first time a spacecraft visited Uranus. its twin spacecraft, Voyager-1 Before deviating from the solar system, it only flew as far as Saturn.


Among man-made probes, none have been able to increase our knowledge of the solar system as much as the two Voyager spacecraft.

Voyager-2 was launched by NASA on August 20, 1977. Its purpose was to study the outer planets of the solar system as well as the interplanetary space. The secondary mission of the spacecraft was to investigate and locate the borders of the solar system, including the Kuiper belt, the heliosphere, and the interstellar space.

This spacecraft was launched sixteen days before Voyager-1, but was overtaken by its counterpart Voyager-1 due to a different trajectory that eventually allowed a side-by-side flyby of Uranus and Neptune.

Voyager 2 reported the first direct measurements of interstellar plasma density and temperature, and images of Jupiter and its moons; Amaltia, Ayo, Callisto, Ganymede And Europe transmitted to the ground.

While passing behind Saturn, the probe probed Saturn’s upper atmosphere with its radio communications to gather information on the temperature and density profile of the atmosphere.

After passing Saturn, Voyager’s camera platform was briefly locked down, and mission plans to Uranus and Neptune were jeopardized. But the mission engineers were able to fix this problem and the probe was able to continue its adventure in the solar system.

Flying past Uranus

The closest flyby to Uranus occurred on January 24, 1986; When Voyager-2 reached a distance of 81,500 km from the superplanet and took the first and only close-up pictures of this planet. During this flyby, Voyager 2 explored the rings around Uranus and discovered 11 of its 27 known moons.

These 11 moons had remained unknown until then; Cordelia, Ophelia, Bianca, Crissida, It’s a robbery, Juliet, Portia, Rosalind, Belinda, clear And Perdita.

The length of a day on Uranus, as measured by Voyager, is 17 hours and 14 minutes. The probe also found that Uranus’ magnetic field, unlike other planets, is not aligned with its axis of rotation.

After this visit, Voyager 2 flew to Neptune and beyond. After giving us information from Neptune, this spacecraft flew to the interstellar space and left the solar system, and NASA uses it to explore the solar system beyond the heliosphere. In December 2018, Voyager Project Scientist, Edward C. Stoneannounced that Voyager 2 reached interstellar space on November 5, 2018.

It is expected that in 2023, Voyager-2 from Pioneer-10 pass and become the second farthest spacecraft from the Sun.
