Trapped between two jet streams, the Great Red Spot swirls around a center of high atmospheric pressure that makes it rotate in the opposite sense of hurricanes on Earth. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter to measure heat and atmospheric currents bubbling up from its warmer interior, the amount of water in the atmosphere and determine if the planet has a rocky core.

Other instruments will study Jupiter’s colossal-sized magnetic field and extensive auroras. NASA’s Juno spacecraft successfully performed its first deep-space maneuver, firing its main engine and changing its trajectory as it continues on its mission towards Jupiter. The burn occurred when Juno was more than 300 million miles (483 million kilometers) away from Earth.
A second deep space maneuver, of comparable duration and velocity change, is planned for September 4. Juno, the fastest solar-powered spacecraft ever made, was launched in August 2011 and finally entered Jupiter's orbit on 8:53 pm of July 4 after a 35-minute engine burn. The mission team was highly praised by Bolden saying that the team and the spacecraft did great despite all of them getting stuck inside the mission control on the Fourth of July when most Americans are merrymaking. The calculated and sensitive engine-burn was conducted to slow down the spacecraft and change its rotation, at the same time stabilizing Juno for the insertion.
Juno's confirmation that says it had already entered orbit is a simple signal broadcasted from 540 miles across in the Solar System. Now that Juno is safely orbiting the planet and harvesting energy from the Sun to accomplish its mission of understanding the composition of the giant gas planet, scientists are anticipating data that will be collected from the spacecraft's up close and personal encounter with the planet. NASA released a fascinating video of Juno's approach to the planet and both the experts and the public are anticipating more videos from the giant planet. On July 4, 2016, you might have noticed a certain name dominating the news and science Twitter amid the typical talk of long weeks and Fourth of July fireworks. Juno was launched on August 5, 2011, making its travel time at about a month short of the five year mark. Juno’s mission goals are primarily to help us understand more about Jupiter, a planet we know very little about because of its distance from Earth. Juno is setting a lot of new records when it comes to doing things humans have never, ever accomplished before.
After the Capture Orbit phase is completed, Juno will transition to a position even closer to Jupiter.
In order to avoid Jupiter’s most deadly radiation fields, Juno will travel in a series of different orbits, taking it in different positions and closer and farther from the planet itself. Scientist Summer Ash explains the interstellar choreography of the Juno spacecraft mission and what we hope to learn from it.

Bolton said even then he would not feel at ease, not until Juno's expansive nine-metre-long solar arrays were pointed back at the sun, crucial for a spacecraft that is relying on sunlight for power."The whole game is, get back to the sun before you run out of battery," Bolton said.
With the exception of the sun, Jupiter is bigger than everything in the solar system put together.
The mysteries of JupiterSeveral spacecraft have flown past Jupiter, beginning with Pioneer 10 in 1973.

Lego figurines representing, from left, the Roman god Jupiter, his wife, Juno, and Galileo Galilei aboard the Juno spacecraft. During its eight years at Jupiter, Galileo confirmed ideas of how Jupiter's diaphanous rings formed out of dust particles blasted off Jupiter's small inner moons. The search for waterIt might seem odd to care about the water on Jupiter, but it is one of the main issues that Juno scientists are focusing on.

It’s interesting to compare Juno to the previous Jupiter orbiter, Galileo, which completed its mission 13 years ago. Galileo had operated for 14 years, whereas Juno will be sent crashing into Jupiter to its destruction just two years from now. No, Juno doesn’t have the capability to give us the pretty pictures that Galileo did, or reveal new secrets about its fascinating moons. Nonetheless, this should be a very interesting two years.

Unlike other space probes to the outer solar system, which use the decay of radioactive plutonium to produce heat and electricity, Juno’s equipped three solar array wings that will both stabilize the craft and provide power from the sun. Since its launch in August 2011, three forces have tugged at NASA’s Juno spacecraft — the sun, Earth and Jupiter — as it speeds half a billion miles across the solar system to the largest planet, Jupiter.
Heat leftover from the planet’s formation still powers winds up to 384 mph (618 kph) that stretch clouds into the familiar pattern of dark bands and lighter zones. Juno will study Jupiter’s auroras and magnetic field that interacts with winds of particles from the sun just as it does here at Earth.
We should be seeing some amazing close-ups of Jovian northern and southern lights through Juno’s Jovian Infrared Auroral Mapper (JIRAM). The mythical god Jupiter drew a veil of clouds around himself to hide his mischief, and his wife, the goddess Juno, was able to peer through the clouds and reveal Jupiter’s true nature. Together, they will place Juno on course for its Earth flyby, which will occur as the spacecraft is completing one elliptical orbit around the sun. Once in orbit, the spacecraft will circle Jupiter 33 times, from pole-to-pole, and use its collection of eight science instruments to probe beneath the gas giant’s obscuring cloud cover.

The engine burn decreased Juno's velocity by 1,212 miles per hour so that Jupiter's gravity was able to capture the spacecraft. If Juno had not successfully entered Jupiter’s orbit, the mission would have been over. Juno is currently in a 53.5 day orbit period around Jupiter, and the goal with this phase is to take Juno into a 14 day orbit. Summer Ash knows everything you didn’t know you wanted to know about the Juno space probe orbiting Jupiter.
But little is known about the interior beneath its colourful cloud stripes.Juno will orbit it 37 times over the next 20 months, with the hopes that it will collect data and images that offer clues to the origins of our solar system and the formation of the planets and moons. NASA's Galileo spacecraft, entering orbit in 1995, dropped a 340 kilogram probe into Jupiter's atmosphere, sending back data that showed Jupiter had strong, turbulent winds and offering details about the composition of its atmosphere. The figures are made of aluminium so they can withstand the extreme conditions of space flight.

It measured the sizzling 2800-degree temperatures of volcanoes on Io, one of the planet's four large moons, and it found evidence of under-ice oceans on the other three moons of Europa, Callisto and Ganymede.Unlike Galileo, Juno will be in an orbit passing over Jupiter's poles, providing a first close look at those regions. Lancee en 2011, la sonde de la NASA a reussit a se placer en orbite autour de Jupiter ce mardi matin a 5h53 (heure francaise) apres un voyage de pres de trois milliards de kilometres, annonce l'Agence aerospatiale americaine dans un communique.
Amazon propose via le vendeur tiers VIPMOVIL, le Samsung Galaxy S7 au prix tres interessant de 516€. Sometimes Earth was the gravitational master as in October 2013, when the probe flew by our planet to get a gravity-assist speed boost en route to Jupiter. With Juno, we will investigate the unknowns of Jupiter's massive radiation belts to delve deep into not only the planet's interior, but into how Jupiter was born and how our entire solar system evolved," Bolded added. Juno is not designed to work in an atmosphere, so NASA will be sending the device into Jupiter’s atmosphere completely, where it will burn up the second it penetrates the cloud tops. But Juno’s camera is on, and the photo accompanying this article is the first picture of Jupiter now that Juno is in-orbit. With repeated close passes over the cloud tops, the spacecraft will measure microwave emissions, the gravity field and the magnetic field, offering glimpses into what is deep inside Jupiter. Une man?uvre particulierement delicate en raison des radiations et de la ceinture de debris entourant la plus grande planete de notre systeme solaire.
More recently, the sun had the most clout as the probe sailed across millions of miles of emptiness between the two planets.
Based on telemetry, the Juno project team believes the burn was accurate, changing the spacecraft’s velocity by about 770 mph (344 meters a second) while consuming about 829 pounds (376 kilograms) of fuel.
The closest approach to Earth, on October 9, 2013, will occur when Juno is at an altitude of about 310 miles (500 kilometers).
Juno is now in what NASA calls the Capture Orbit Phase, which will end on October 14th, 2016. When Juno entered Jupiter’s orbit on July 4, it entered at its closest point to Jupiter in its orbit. Apres deux rotations de 53,5 jours, l'appareil de 3,6 tonnes, fonctionnant a l'energie solaire, viendra se placer a partir d'octobre 2016 dans une orbite de 14 jours. This information will hopefully also tell us more about how gas giant planets in general work, so we can finally understand the origin of planetary systems in other solar systems as well as ours.
All of Juno’s science instruments will be turned on during this period, and these instruments will need to be observed and calibrated now that the spacecraft is at its destination. Elle s'approchera, ainsi, encore un peu plus de Jupiter pour s'atteler a l'etude de la geante gazeuse. It will make this trip back and forth four times before entering the Science Orbit phase, which is when the bulk of scientific observation will occur. La sonde restera en orbite autour de la planete jusqu'en fevrier 2018 afin d'essayer de percer ses mysteres.
Pendant ces 20 mois, Juno etudiera notamment l'atmosphere, la magnetosphere, la composition, ou encore la structure interne de la planete. L'une des grandes questions que se posent les scientifiques est par ailleurs de savoir si Jupiter possede un noyau.
Les donnees relevees par la sonde permettront de mieux comprendre la naissance de la geante gazeuse et, finalement, des autres planetes du systeme solaire.
