NASA’s Juno Spacecraft Completes Fifth Jupiter Flyby

NASA's Juno spacecraft will make its fifth flyby over Jupiter's mysterious cloud tops on Monday, March 27, at 1:52 a.m. PDT (4:52 a.m. EDT, 8:52 UTC).

At the time of closest approach (called perijove), Juno will be about 2,700 miles (4,400 kilometers) above the planet's cloud tops, traveling at a speed of about 129,000 miles per hour (57.8 kilometers per second) relative to the gas-giant planet. All of Juno's eight science instruments will be on and collecting data during the flyby.

"This will be our fourth science pass -- the fifth close flyby of Jupiter of the mission -- and we are excited to see what new discoveries Juno will reveal,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "Every time we get near Jupiter’s cloud tops, we learn new insights that help us understand this amazing giant planet."

The Juno science team continues to analyze returns from previous flybys. Scientists have discovered that Jupiter's magnetic fields are more complicated than originally thought, and that the belts and zones that give the planet's cloud tops their distinctive look extend deep into the its interior. Observations of the energetic particles that create the incandescent auroras suggest a complicated current system involving charged material lofted from volcanoes on Jupiter's moon Io.

Juno spacecraft reveals a more complex Jupiter

Jupiter’s scientific portrait is getting repainted.

NASA’s Juno spacecraft swooped within about 5,000 kilometers of Jupiter’s cloud tops on August 27, 2016, giving scientists their first intimate look at the gas giant. The data are revealing surprising details about Jupiter’s gravity, powerful magnetic field and ammonia-rich weather system. The findings, which appear in two studies in the May 26 Science, suggest researchers may not only need to revamp their view of Jupiter but also their ideas about how planetary systems form and evolve.

“We went in with a preconceived notion of how Jupiter worked, and I would say we have to eat some humble pie,” says Juno mission leader Scott Bolton, a planetary scientist at the Southwest Research Institute in San Antonio.

Scientists thought that beneath its thick clouds, Jupiter would be uniform and boring. But Juno revealed the planet is anything but, Bolton says. “Jupiter is much more complex deep down than anyone anticipated.”

For starters, measurements of Jupiter’s gravity, determined from the tug of the planet on the spacecraft, suggest that the planet doesn’t have a solid, compact core, Bolton and colleagues report in one of the new papers. Instead, the core is probably large and diffuse, possibly as big as half the planet’s radius, the team concludes. “Nobody anticipated that,” Bolton says.

Imke de Pater, a planetary scientist at the University of California, Berkeley who was not involved in the studies, says the new gravity measurements should allow scientists to get a better handle on the structure of the planet’s core. But, she notes, because of the mathematics involved, it won’t be an easy task.

She was even more surprised by new measurements of Jupiter’s magnetic field, which is the strongest in the solar system. The Juno data reveal the magnetic field is almost twice as strong as expected in some places. But the field’s strength varies from location to location, growing stronger than expected in some areas and weaker in others. The data support the idea that the magnetic field originates from circulating electric currents in one of the planet’s outer layers of molecular hydrogen.

In a complementary paper, astrophysicist John Connerney of NASA’s Goddard Space Flight Center in Greenbelt, Md., and colleagues look at how Jupiter’s magnetic field interacts with the solar wind, a stream of charged particles flowing from the sun. That interaction influences Jupiter’s auroras, which Juno captured in ultraviolet and infrared images. Studying the brilliant light shows at the planet’s poles, the team observed particles falling into the planet’s atmosphere, similar to what happens on Earth. But there were also beams of electrons actually shooting out of Jupiter’s atmosphere, which isn’t seen on Earth. The finding suggests the gas giant interacts very differently with the solar wind, the team writes.

Another oddity, described by Bolton’s team, is how ammonia wells up from the depths of Jupiter’s atmosphere. The upwelling resembles a feature on Earth called a Hadley cell, where warm air at our equator rises and creates trade winds, hurricanes and other forms of weather. Jupiter’s ammonia cycling looks similar. But because Jupiter lacks a solid surface, the upwelling probably works in a completely different way than on Earth. Figuring out how the phenomenon occurs on Jupiter may help scientists better understand the atmospheres of other planets.

Jupiter is a standard of comparison for all gas giants, within and beyond the solar system. “What we learn about Jupiter will impact our understanding of all giant planets,” Bolton says. Most planetary systems have Jupiter-like planets. By helping researchers determine how the one in our solar system formed and operates, the new data could give clues to how other planetary systems evolved as well.

​

Even a casual observer can see how complex Jupiter might be. Its Great Red Spot is one of the most iconic objects in our Solar System. The Great Red Spot, which is a continuous storm 2 or 3 times as large as Earth, along with Jupiter’s easily-seen storm cloud belts, are visual clues that Jupiter is a complex place.

We’ve been observing the Great Red Spot for almost 200 years, so we’ve known for a long time that something special is happening at Jupiter. Now that the Juno probe is there, we’re finding that Jupiter might be a more surprising place than we thought.

“There is so much going on here that we didn’t expect that we have had to take a step back and begin to rethink of this as a whole new Jupiter.” – Scott Bolton, Juno’s Principal Investigator at the Southwest Research Institute.
So far, the stunning images delivered to us by the JunoCam have stolen the show. But Juno is a science mission, and the fantastic images we’re feasting on might stir the imagination, but it’s the science that’s at the heart of the mission.

BEST JUPITER IMAGES FROM JUNO … SO FAR

These Photos are AMAZING!!

[video=youtube;3kQbTBt418o]https://www.youtube.com/watch?v=3kQbTBt418o[/video]


The original plans for the Juno mission to Jupiter didn’t include a color camera. You don’t need color images when the mission’s main goals are to map Jupiter’s magnetic and gravity fields, determine the planet’s internal composition, and explore the magnetosphere.

But a camera was added to the manifest, and the incredible images from the JunoCam have been grabbing the spotlight.

As an instrument where students and the public can choose the targets, JunoCam is a “public outreach” camera, meant to educate and captivate everyday people.

“The whole endeavor of JunoCam was to get the public to participate in a meaningful way,” said Candy Hansen, Juno co-investigator at the Planetary Science Institute in Tucson, Arizona, speaking at a press conference last week to showcase Juno’s science and images.

And participate they have. Hundreds of ‘amateur’ image processing enthusiasts have been processing raw data from the JunoCam, turning them into stunning images, many reminiscent of a swirling Van Gogh ‘starry night’ or a cloudscape by Monet.

'It's Snowing on Jupiter': Stunning Photos Show Clouds High in Gas Giant's Skies

Not all of Jupiter's clouds are huge, swirling, otherworldly beasts.
Spectacular new images captured by NASA's Jupiter-orbiting Juno spacecraft show fluffy-looking white clouds casting their comparably tiny shadows on the giant planet's monstrous, multicolored cloud decks.

The white clouds, which get up to 50 miles (80 kilometers) wide or so, are high up in Jupiter's atmosphere — so high that they're very cold, and the material they shed is therefore almost certainly frozen, Juno team members said.

"It's snowing on Jupiter, and we're seeing how it works," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said during a news conference Thursday (May 25).

Juno spacecraft to fly over Jupiter's Great Red Spot July 10:

Just days after celebrating its first anniversary in Jupiter orbit, NASA's Juno spacecraft will fly directly over Jupiter's Great Red Spot, the gas giant's iconic, 10,000-mile-wide (16,000-kilometer-wide) storm. This will be humanity's first up-close and personal view of the gigantic feature—a storm monitored since 1830 and possibly existing for more than 350 years.

"Jupiter's mysterious Great Red Spot is probably the best-known feature of Jupiter," said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "This monumental storm has raged on the solar system's biggest planet for centuries. Now, Juno and her cloud-penetrating science instruments will dive in to see how deep the roots of this storm go, and help us understand how this giant storm works and what makes it so special."

Juno Scientists Prepare for Seventh Science Pass of Jupiter

NASA's Juno spacecraft will make its seventh science flyby over Jupiter's mysterious cloud tops on Friday, Sept. 1, at 2:49 p.m. PDT (5:49 p.m. EDT and 21:49 UTC). At the time of perijove (defined as the point in Juno's orbit when it is closest to the planet's center), the spacecraft will be about 2,200 miles (3,500 kilometers) above the planet's cloud tops.

Juno launched on Aug. 5, 2011, from Cape Canaveral, Florida, and arrived in orbit around Jupiter on July 4, 2016. During its mission of exploration, Juno soars low over the planet's cloud tops -- as close as about 2,100 miles (3,400 kilometers). During these flybys, Juno is probing beneath the obscuring cloud cover of Jupiter and studying its auroras to learn more about the planet's origins, structure, atmosphere and magnetosphere.

NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed by NASA's Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. JPL is a division of Caltech in Pasadena, California.

​

Even after decades of study, Jupiter’s atmosphere continues to be something of a mystery to scientists. Consistent with the planet’s size, its atmosphere is the largest in the Solar System, spanning over 5,000 km (3,000 mi) in altitude and boasting extremes in temperature and pressure. On top of that, the planet’s atmosphere experiences the most powerful auroras in the Solar System.

Studying this phenomena has been one of the main goals of the Juno probe, which reached Jupiter on July 5th, 2016. However, after analyzing data collected by the probe’s instruments, scientists at Johns Hopkins University Applied Physics Laboratory (JHUAPL) were surprised to find that Jupiter’s powerful magnetic storms do not have the same source as they do on Earth.

The study which details these findings, “Discrete and Broadband Electron Acceleration in Jupiter’s Powerful Aurora“, recently appeared in the scientific journal Nature. Led by Barry Mauk, a scientist with the JHUAPL, the team analyzed data collected by Juno’s Ultraviolet Spectrograph (UVS) and Jovian Energetic Particle Detector Instrument (JEDI) to study Jupiter’s polar regions.​

Juno Isn’t Exactly Where it’s Supposed To Be.

In the early 1960s, scientists developed the gravity-assist method, where a spacecraft would conduct a flyby of a major body in order to increase its speed. Many notable missions have used this technique, including the Pioneer, Voyager, Galileo, Cassini, and New Horizons missions. In the course of many of these flybys, scientists have noted an anomaly where the increase in the spacecraft’s speed did not accord with orbital models.

This has come to be known as the “flyby anomaly”, which has endured despite decades of study and resisted all previous attempts at explanation. To address this, a team of researchers from the University Institute of Multidisciplinary Mathematics at the Universitat Politecnica de Valencia have developed a new orbital model based on the maneuvers conducted by the Juno probe.

The study, which recently appeared online under the title “A Possible Flyby Anomaly for Juno at Jupiter“, was conducted by Luis Acedo, Pedro Piqueras and Jose A. Morano. Together, they examined the possible causes of the so-called “flyby anomaly” using the perijove orbit of the Juno probe. Based on Juno’s many pole-to-pole orbits, they not only determined that it too experienced an anomaly, but offered a possible explanation for this.
