Juno Mission Archives
canada goose coats on sale In July of 2016, the Juno spacecraft established orbit around Jupiter, becoming the first spacecraft since the Galileo probe to study the planet directly. Since that time, the probe has been sending back vital information about Jupiter’s atmosphere, magnetic field and weather patterns. With every passing orbit (known as a perijove, which take place every 53 days), the spacecraft has revealed more about Jupiter atmosphere, weather patterns, and magnetic environment. canada goose coats on sale
In addition, Juno recently discovered something interesting about Jupiter closest orbiting moon Io. Based on data collected by its goose outlet canada Jovian InfraRed Auroral Mapper (JIRAM) instrument, Juno detected a new heat source close to the south pole of Io that could indicate the presence of a previously undiscovered volcano. This is just the latest discovery made by canada goose outlet shop the probe during its mission, which canada goose outlet canada NASA recently extended to 2021.

canada goose black friday sale The infrared data was collected canada goose outlet on Dec. 16th, 2017, when the Juno spacecraft was about 470,000 km (290,000 mi) away from Io. As Alessandro Mura, a Juno co investigator from the National Institute for Astrophysics (INAF) in Rome, explained in a recent NASA press release: canada goose black friday sale
canada goose factory sale “The new Io hotspot JIRAM picked up is about 200 miles (300 kilometers) from the nearest previously mapped hotspot. We are not ruling out movement official canada goose outlet or modification of a previously discovered hot spot, but it is difficult to imagine one could travel such a distance and still be considered the same feature.” canada goose factory sale
uk canada goose Aside from Juno and Galileo, many NASA missions have visited or passed through the Jovian System in the past few decades. These have including the Pioneer 10 and 11 missions in 1973/74, the Voyager 1 and 2 missions in 1979, and the Cassini and New Horizons missions in 2000 and 2007, respectively. Each of these missions managed to snap pictures of the Jovians moons on their way to the outer Solar System. uk canada goose

Canada Goose online Combined with ground based observations, scientists have accounted for over 150 volcanoes on the surface of Io so far, with estimates claiming there canada goose outlet sale could over 400 in total. Since it entered Jupiter orbit on July 4th, 2016, the Juno probe has traveled nearly 235 million km (146 million mi) from one pole to other. On July 16th, Juno will conduct its 13th perijove maneuver, once again passing low over Jupiter cloud tops at a distance of about 3,400 km (2,100 mi). Canada Goose online
Canada Goose Online During these canada goose outlet black friday flybys, Juno probes beneath the upper atmosphere to study the planet auroras to learn more about it structure, atmosphere and magnetosphere. By shedding light on these characteristics, the Juno probe will also teach us more about the planet origins and evolution. This in turn will teach scientists a great deal more about the formation and evolution of our Solar System, and perhaps how life began here. Canada Goose Online

Canada Goose Jackets Interestingly, some of the most recent information to come canada goose factory outlet from the mission involves how two of its moons affect one of Jupiter most interesting atmospheric phenomenon. As they revealed in a recent study, an international team of researchers canada goose outlet online discovered how Io and Ganymede leave in the planet aurorae. Credit: (c) Science (2018).

cheap Canada Goose Much like aurorae here on Earth, Jupiter’s aurorae are produced in its upper atmosphere when high energy electrons interact with the planet powerful magnetic field. However, as theJuno probe recently canada goose outlet store demonstrated using data gathered by Ultraviolet Spectrograph (UVS) canada goose outlet online uk and Jovian Energetic Particle Detector Instrument (JEDI), Jupiter magnetic field is significantly more powerful than anything we see on Earth. cheap Canada Goose
canadian goose jacket In addition to reaching power levels 10 to 30 times greater than anything higher than what is experienced here on Earth (up to 400,000 electron volts), Jupiter norther and southern auroral storms also have oval shaped disturbances that appear whenever Io and Ganymede pass close to the planet. As they explain in their study: canadian goose jacket
northern and a southern main auroral oval are visible, surrounded by small emission features associated with the Galilean moons. We present infrared observations, obtained with the Juno spacecraft, showing that in the case of Io, this emission exhibits a swirling pattern that is similar in appearance to a von Krmn vortex street.
A Von Krmn vortex street, a concept in canada goose jacket outlet fluid dynamics, is basically a repeating pattern of swirling vortices caused by a disturbance. In this case, the team found evidence of a vortex streaming for hundreds of kilometers when Io passed close to the planet, but which then disappeared as the moon moved farther away from the planet.

Canada Goose sale The team also found two spots in the auroral belt canada goose outlet new york city created by Ganymede, where the extended tail from the main auroral spots eventually split in two. While the team was not sure what causes this split, they venture that it could be caused by interaction between Ganymede and Jupiter magnetic field (since Ganymede is the only Jovian moon to have its own magnetic field). Canada Goose sale
canada goose uk shop These features, they claim, suggest that magnetic interactions between Jupiter and Ganymede are more complex than previously thought. They also indicate that neither of the footprints were where they expected to find them, which suggests that models of the planet magnetic interactions with its moons may be in need of revision. canada goose uk shop
canada goose uk outlet Studying Jupiter magnetic storms is one of the primary goals of the Juno mission, as is learning more about the planet interior structure and how it has evolved over time. In so doing, astronomers hope to learn more about how the Solar System came to canada goose outlet be. NASA also recently extended the mission to 2021, giving it three more years to gather data on these mysteries. canada goose uk outlet

canada goose uk black friday Volcanic activity on Io was discovered by Voyager 1 imaging scientist Linda Morabito. She spotted a little bump canada goose outlet nyc on Io limb while analyzing a Voyager image and thought at first it was an undiscovered moon. Moments later she realized that wasn possible it would have been seen by earthbound telescopes long ago. Morabito and the Voyager team canada goose outlet jackets soon came to realize they were seeing a volcanic plume rising 190 miles (300 km) off the surface of Io. It was the first time in history that an active volcano had been detected beyond the Earth canada goose uk black friday.
