    While Voyager 1 is on flight path that will take it out of the solar system, Voyager 2 continued beyond Saturn and flew past Uranus on Jan. 24, Many of today's awards went to individuals and teams responsible for some of the extraordinary engineering measures taken during the mission to ensure that the nine-year-old spacecraft world.   [/caption] Voyager 2 is the only spacecraft that has flown close by one of the more enigmatic planets in our solar system (and the butt of many one-liners): Uranus. It .

    These two pictures of Uranus were compiled from images recorded by Voyager 2 on Jan. 1O, , when the NASA spacecraft was 18 million kilometers (11 million.   To reach Uranus, Voyager 2, launched in August , cruised unharmed through the asteroid belt between Mars and Jupiter, flew past Jupiter on July 9, .

    Uranus is the seventh planet from the name "Uranus" is a reference to the Greek god of the sky, ing to Greek mythology, Uranus was the grandfather of Zeus and father of Cronus ().It has the third-largest planetary radius and fourth-largest planetary mass in the Solar is similar in composition to Neptune, and both have bulk chemical compositions which differ. Highlights Reanalysis of Voyager Uranus radio occultation results yields new profiles for CH 4. Model CCD spectra are computed for each profile using compact cloud layers. The fit to observed spectra is best with profiles having about four pressure percent deep methane. The best model upper compact cloud matches the CH 4 occultation cloud. From 45 to 60°S methane is increasingly depleted to a.

Voyager 2 radioed thousands of images and voluminous amounts of other scientific data on the planet, its moons, rings, atmosphere, interior and the magnetic environment surrounding Uranus.

Since launch on Aug. 20,Voyager 2's itinerary has taken the spacecraft to Jupiter in JulySaturn in Augustand then Uranus. Abstract. New, high-resolution spectrograms of the Voyager-2 radio observations at Uranus have been produced from the original, six-second Planetary Radio Astronomy (PRA) data and these show a number of new features which were not obvious in pre-vious versions.

Among these new features are the detailed structure of the so-called. This is a real-time indicator of Voyager 1's distance from Earth in astronomical units (AU) and either miles (mi) or kilometers (km).

Note: Because Earth moves around the sun faster than Voyager 1 is speeding away from the inner solar system, the distance between Earth and the spacecraft actually decreases at certain times of year.

In situ measurements of Uranus' magnetosphere from the Voyager 2 flyby in provide the only direct evidence of magnetospheric transport processes responsible for this atmospheric escape at Uranus.

Analysis of high‐resolution Voyager 2 magnetic field data in Uranus' magnetotail reveals the presence of a loop‐like plasmoid filled with. New radio spectrograms have been prepared to clarify the behavior of such emissions, using both the usual second, log-averaged data and the original 6-second PRA data, the latter showing a number of interesting new features.

Now Voyager. Among the radio emissions detected with Voyager 2 at Uranus was a so-called broadband bursty or ``b-bursty'' component at frequencies of kHz, which was first observed √ just before closest approach and then during subsequent planetary rotations about hours before the more prominent smooth component.

Although not obvious for individual rotations because of the bursty nature of. Voyager II encountered the planet Uranus and discovered its Rings in January, One startling aspect of Uranus is that its axis of rotation is inclined 97° 54 min from its orbital plane.

Uranus lies on its side, with its rings vertical. Of the 9 rings of Uranus, six are inclined with respect to. This is an image of the planet Uranus taken by the spacecraft Voyager 2. InDr. Jeffrey D. Thompson, D.C., B.F.A. was approached by representatives working with NASA and JPL to explore a series of powerful recordings which the Voyager I & II Spacecraft had sent back from Jupiter, Saturn, Uranus and Neptune.

Voyager 2 radio occultation measurements of the Uranian atmosphere were obtained between 2 and 7 degrees south latitude.

Initial atmospheric temperature profiles extend from pressures of 10 to millibars over a height range of about kilometers. Comparison of radio and infrared results yields mole fractions near the tropopause of and ± for molecular hydrogen and helium.

Voyager 2: the story of its mission so far – in pictures Possible variations in chemical composition from one part of Saturn’s ring system to another are visible in this Voyager 2 picture. Image of Uranus’ crescent taken by a departing Voyager 2 on Janu (NASA/JPL) 27 years ago today, JanuNASA’s Voyager 2 spacecraft sped past Uranus.

The exploration of Uranus has, to date, been solely through telescopes and a lone probe by NASA's Voyager 2 spacecraft, which made its closest approach to Uranus on Janu Voyager 2 discovered 10 moons, studied the planet's cold atmosphere, and examined its ring system, discovering two new also imaged Uranus' five large moons, revealing that their surfaces are covered with.

Voyager 2 returned this picture of the Uranus rings on Jan. 22,from a distance of million kilometers ( million miles). All nine known rings are visible in this image, a second exposure through the clear filter on Voyager's narrow-angle camera.

The rings are quite dark and very narrow. Color spectrograms: Voyager 1: L-Mode spectrograms PDF, M-Mode spectrograms PDF.

The Voyager program is an American scientific program that employs two robotic probes, Voyager 1 and Voyager 2, launched in to take advantage of a favorable alignment of Jupiter, Saturn, Uranus, and Neptune. Although their original mission was to study only the planetary systems of Jupiter and Saturn, Voyager 2 continued on to Uranus and Neptune.

No new missions are planned to Uranus or Neptune – the Voyager 2 images remain the state of the art. Few expeditions in the entire history of mankind have notched up so many scientific.Goals: Voyager 1 and 2 were designed to take advantage of a rare planetary alignment to explore the outer solar system.

Voyager 1 targeted Jupiter and Saturn before continuing on to chart the far edges of our solar system. Voyager 2 targeted Jupiter, Saturn, Uranus and Neptune before joining its sister probe on their interstellar mission. Consequently, as Voyager 2 passed close to Uranus all those years ago, one of its tasks was to carefully measure Uranus’ magnetic field.

Now, Goddard’s Gina DiBraccio and Dan Gershman have reanalysed those magnetometer observations at greater fidelity than ever before, marking new data points ever seconds.
