Космическое агентство США продлило сроки активного существования КА JUNO

Поскольку космический зонд JUNO за два года на орбите Юпитера показал себя с хорошей стороны, то космическое агентство США решило продлить его срок активного существования. При этом, изначально решение об окончании этой миссии планировалось принимать уже эти летом.
 Запуск спутника произошел в августе 2011 года, а Юпитера он достиг 4 июля 2016 года и его полет к Юпитеру сопровождался обнаружением проблем с функционированием двух контрольных клапанов для подачи гелия. Однако, из-за того что радиационная обстановка на орбите оказалось менее жесткой чем ожидалось, то теперь ориентировочным сроком окончания работы космического аппарата называется 2021 год, когда будет завершено получение основных научных данных.
 Финансирование космического аппарата JUNO будет продолжаться до 2022 года и включает в себя ассигнования на обработку данных.

[SIZE=8]Dark and Stormy Jupiter[/SIZE]



This image captures the intensity of the jets and vortices in Jupiter's North North Temperate Belt.

NASA's Juno spacecraft took this color-enhanced image at 10:31 p.m. PDT on May 23, 2018 (1:31 a.m. EDT on May 24), as Juno performed its 13th close flyby of Jupiter. At the time, the spacecraft was about 4,900 miles (7,900 kilometers) fr om the tops of the clouds of the gas giant planet at a northern latitude of about 41 degrees. The view is oriented with south on Jupiter toward upper left and north toward lower right.

Спойлер

The North North Temperate Belt is the prominent reddish-orange band left of center. It rotates in the same direction as the planet and is predominantly cyclonic, which in the northern hemisphere means its features spin in a counter-clockwise direction. Within the belt are two gray-colored anticyclones.

To the left of the belt is a brighter band (the North North Temperate Zone) with high clouds whose vertical relief is accentuated by the low angle of sunlight near the terminator. These clouds are likely made of ammonia-ice crystals, or possibly a combination of ammonia ice and water. Although the region as a whole appears chaotic, there is an alternating pattern of rotating, lighter-colored features on the zone's north and south sides.

Scientists think the large-scale dark regions are places wh ere the clouds are deeper, based on infrared observations made at the same time by Juno's JIRAM experiment and Earth-based supporting observations. Those observations show warmer, and thus deeper, thermal emission from these regions.

To the right of the bright zone, and farther north on the planet, Jupiter's striking banded structure becomes less evident and a region of individual cyclones can be seen, interspersed with smaller, darker anticyclones.

[SIZE=8]Chaotic Clouds of Jupiter[/SIZE]



This image captures swirling cloud belts and tumultuous vortices within Jupiters northern hemisphere.

NASAs Juno spacecraft took this color-enhanced image at 10:23 p.m. PDT on May 23, 2018 (1:23 a.m. EDT on May 24), as the spacecraft performed its 13th close flyby of Jupiter. At the time, Juno was about 9,600 miles (15,500 kilometers) from the planet's cloud tops, above a northern latitude of 56 degrees.

Спойлер

The region seen here is somewhat chaotic and turbulent, given the various swirling cloud formations. In general, the darker cloud material is deeper in Jupiters atmosphere, while bright cloud material is high. The bright clouds are most likely ammonia or ammonia and water, mixed with a sprinkling of unknown chemical ingredients.

A bright oval at bottom center stands out in the scene. This feature appears uniformly white in ground-based telescope observations. However, with JunoCam we can observe the fine-scale structure within this weather system, including additional structures within it. There is not significant motion apparent in the interior of this feature; like the Great Red Spot, its winds probably slows down greatly toward the center.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft's JunoCam imager. The view is a composite of several separate JunoCam images that were re-projected, blended, and healed.

High-Altitude Jovian Clouds



This image captures a high-altitude cloud formation surrounded by swirling patterns in the atmosphere of Jupiter's North North Temperate Belt region.

Спойлер

The North North Temperate Belt is one of Jupiter's many colorful, swirling cloud bands. Scientists have wondered for decades how deep these bands extend. Gravity measurements collected by Juno during its close flybys of the planet have now provided an answer. Juno discovered that these bands of flowing atmosphere actually penetrate deep into the planet, to a depth of about 1,900 miles (3,000 kilometers).

NASA's Juno spacecraft took this color-enhanced image at 10:11 p.m. PDT on July 15, 2018 (1:11 a.m. EDT on July 16), as the spacecraft performed its 14th close flyby of Jupiter. At the time, Juno was about 3,900 miles (6,200 kilometers) from the planet's cloud tops, above a latitude of 36 degrees.

This natural color view offers an approximation of what Jupiter would look like to human eyes from Juno's vantage point near the time of closest approach in its orbit. Jupiter's stunning appearance is due to its atmosphere of colorful cloud bands and spots. The vivid red and orange hues are created by chemicals of uncertain composition called "chromophores."

How a NASA Scientist Looks in the Depths of the Great Red Spot to Find Water on Jupiter

For centuries, scientists have worked to understand the makeup of Jupiter. It's no wonder: this mysterious planet is the biggest one in our solar system by far, and chemically, the closest relative to the Sun. Understanding Jupiter is key to learning more about how our solar system formed, and even about how other solar systems develop.

But one critical question has bedeviled astronomers for generations: Is there water deep in Jupiter's atmosphere, and if so, how much?

Gordon L. Bjoraker, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, reported in a recent paper in the Astronomical Journalthat he and his team have brought the Jovian research community closer to the answer.

By looking fr om ground-based telescopes at wavelengths sensitive to thermal radiation leaking fr om the depths of Jupiter's persistent storm, the Great Red Spot, they detected the chemical signatures of water above the planet's deepest clouds. The pressure of the water, the researchers concluded, combined with their measurements of another oxygen-bearing gas, carbon monoxide, imply that Jupiter has 2 to 9 times more oxygen than the Sun. This finding supports theoretical and computer-simulation models that have predicted abundant water (H2O) on Jupiter made of oxygen (O) tied up with molecular hydrogen (H2).

This animation takes the viewer on a simulated flight into, and then out of, Jupiter's upper atmosphere at the location of the Great Red Spot. It was created by combining an image fr om the JunoCam imager on NASA's Juno spacecraft with a computer-generated animation. The perspective begins about 2,000 miles (3,000 kilometers) above the cloud tops of the planet's southern hemisphere. The bar at far left indicates altitude during the quick descent; a second gauge next to that depicts the dramatic increase in temperature that occurs as the perspective dives deeper down. The clouds turn crimson as the perspective passes through the Great Red Spot. Finally, the view ascends out of the spot.

The revelation was stirring given that the team's experiment could have easily failed. The Great Red Spot is full of dense clouds, which makes it hard for electromagnetic energy to escape and teach astronomers anything about the chemistry within.

"It turns out they're not so thick that they block our ability to see deeply," said Bjoraker. "That's been a pleasant surprise."

New spectroscopic technology and sheer curiosity gave the team a boost in peering deep inside Jupiter, which has an atmosphere thousands of miles deep, Bjoraker said: "We thought, well, let's just see what's out there."

The data Bjoraker and his team collected will supplement the information NASA's Juno spacecraft is gathering as it circles the planet fr om north to south once every 53 days.

, Juno is looking for water with its own infrared spectrometer and with a microwave radiometer that can probe deeper than anyone has seen — to 100 bars, or 100 times the atmospheric pressure at Earth's surface. (Altitude on Jupiter is measured in bars, which represent atmospheric pressure, since the planet does not have a surface, like Earth, fr om which to measure elevation.)

If Juno returns similar water findings, thereby backing Bjoraker's ground-based technique, it could open a new window into solving the water problem, said Goddard's Amy Simon, a planetary atmospheres expert.

"If it works, then maybe we can apply it elsewh ere, like Saturn, Uranus or Neptune, wh ere we don't have a Juno," she said.

Juno is the latest spacecraft tasked with finding water, likely in gas form, on this giant gaseous planet.

Water is a significant and abundant molecule in our solar system. It spawned life on Earth and now lubricates many of its most essential processes, including weather. It's a critical factor in Jupiter's turbulent weather, too, and in determining whether the planet has a core made of rock and ice.

Jupiter is thought to be the first planet to have formed by siphoning the elements left over from the formation of the Sun as our star coalesced from an amorphous nebula into the fiery ball of gases we see today. A widely accepted theory until several decades ago was that Jupiter was identical in composition to the Sun; a ball of hydrogen with a hint of helium — all gas, no core.

But evidence is mounting that Jupiter has a core, possibly 10 times Earth's mass. Spacecraft that previously visited the planet found chemical evidence that it formed a core of rock and water ice before it mixed with gases from the solar nebula to make its atmosphere. The way Jupiter's gravity tugs on Juno also supports this theory. There's even lightning and thunder on the planet, phenomena fueled by moisture.

"The moons that orbit Jupiter are mostly water ice, so the whole neighborhood has plenty of water," said Bjoraker. "Why wouldn't the planet — which is this huge gravity well, wh ere everything falls into it — be water rich, too?"

The water question has stumped planetary scientists; virtually every time evidence of H2O materializes, something happens to put them off the scent. A favorite example among Jupiter experts is NASA's Galileo spacecraft, which dropped a probe into the atmosphere in 1995 that wound up in an unusually dry region. "It's like sending a probe to Earth, landing in the Mojave Desert, and concluding the Earth is dry," pointed out Bjoraker.

In their search for water, Bjoraker and his team used radiation data collected from the summit of Maunakea in Hawaii in 2017. They relied on the most sensitive infrared telescope on Earth at the W.M. Keck Observatory, and also on a new instrument that can detect a wider range of gases at the NASA Infrared Telescope Facility.

The idea was to analyze the light energy emitted through Jupiter's clouds in order to identify the altitudes of its cloud layers. This would help the scientists determine temperature and other conditions that influence the types of gases that can survive in those regions.

Planetary atmosphere experts expect that there are three cloud layers on Jupiter: a lower layer made of water ice and liquid water, a middle one made of ammonia and sulfur, and an upper layer made of ammonia.

To confirm this through ground-based observations, Bjoraker's team looked at wavelengths in the infrared range of light wh ere most gases don't absorb heat, allowing chemical signatures to leak out. Specifically, they analyzed the absorption patterns of a form of methane gas. Because Jupiter is too warm for methane to freeze, its abundance should not change from one place to another on the planet.

"If you see that the strength of methane lines vary from inside to outside of the Great Red Spot, it's not because there's more methane here than there," said Bjoraker, "it's because there are thicker, deep clouds that are blocking the radiation in the Great Red Spot."

Bjoraker's team found evidence for the three cloud layers in the Great Red Spot, supporting earlier models. The deepest cloud layer is at 5 bars, the team concluded, right wh ere the temperature reaches the freezing point for water, said Bjoraker, "so I say that we very likely found a water cloud." The location of the water cloud, plus the amount of carbon monoxide that the researchers identified on Jupiter, confirms that Jupiter is rich in oxygen and, thus, water.

Bjoraker's technique now needs to be tested on other parts of Jupiter to get a full picture of global water abundance, and his data squared with Juno's findings.

"Jupiter's water abundance will tell us a lot about how the giant planet formed, but only if we can figure out how much water there is in the entire planet," said Steven M. Levin, a Juno project scientist at NASA's Jet Propulsion Laboratory in Pasadena, California.

Ученые НАСА нашли "океаны воды" под облаками Юпитера
17:3630.08.2018

МОСКВА, 30 авг – РИА Новости.  Планетологи впервые смогли измерить количество воды внутри Большого красного пятна Юпитера и подтвердить, что в нижних слоях его атмосферы присутствует гигантское количество влаги. Их выводы были представлены в Astronomical Journal.
 "Когда мы отправили зонд "Галилео" к Юпитеру и запустили зонд в его атмосферу, мы случайно попали в своеобразную "пустыню", где почти не было ни аммиака, ни воды. Это ошибочно заставило нас полагать, что эти вещества отсутствуют на планете. Представьте себе, если бы инопланетяне прилетели на Землю и приземлились в Мохаве, они бы подумали, что на ней нет воды", — рассказывает Гордон Бьорейкер (Godon Bjoraker) из Центра космических полетов НАСА имени Годдарда (США).

Тайны пятой планеты

До прибытия зонда "Галилео" к Юпитеру большинство планетологов считало, что в атмосфере газового гиганта почти нет аммиака и воды. Спускаемый аппарат, сброшенный межпланетной станцией, впервые показал, что это не так. Ему не удалось найти следы этих веществ в верхних слоях атмосферы, в так называемом облачном слое, однако под ним "Галилео" обнаружил большие количества влаги и соединения азота и водорода.
Проверка данных, собранных "Галилео", затруднялась тем, что Юпитер окружают облака из электронов и других заряженных частиц, мешающие изучению его недр при помощи радиотелескопов. Они вынуждают астрономы идти на всяческие ухищрения для того, чтобы заглянуть в атмосферу Юпитера на глубину в несколько десятков километров.
Два года назад Бьорейкер и его коллеги впервые смогли "пробиться" через эту завесу, разработав новую методику обработки данных, поступавших с наземных радиотелескопов во время наблюдений за планетой-гигантом. Им удалось доказать, что аммиак действительно присутствует внутри Большого красного пятна и в других регионах Юпитера.
Добившись успеха, ученые попытались глубже проникнуть внутрь атмосферы планеты, используя не обычные радиотелескопы, а их микроволновые аналоги, способные улавливать излучение молекул, находящихся на глубине примерно в 90-100 километров от верхней кромки облаков.

 Потайной океан

Как показали эти замеры, почти весь нижний слой облаков Юпитера на этой глубине состоит из воды, и не содержит в себе аммиака и различных органических соединений, присутствующих в верхних слоях атмосферы.
Подобное открытие, как отмечают планетологи, одновременно подтверждает замеры "Галилео" и говорит о том, что большинство современных представлений об устройстве Большого красного пятна не соответствуют действительности.
В частности, ученые раньше считали, что вода в нем присутствует только у самой "ножки" урагана, однако замеры Бьорейкера и его коллег говорят о том, что воды там заметно больше и что она проникает почти до самой "вершины" этого антициклона. Если это так, то тогда можно говорить, что основная масса воздуха в урагане движется не горизонтально, как предполагалось раньше, а вертикально.
Вкупе с другими замерами, все это говорит о том, что недра Юпитера содержат в себе как минимум в два раза больше кислорода, чем Солнце, с поправкой на разницу в массе, и заметно больше воды, чем светило.
Почему это важно? Как объясняет Бьорейкер, это открытие говорит в пользу того, что планета-гигант имеет каменистое ядро, так как в противном случае ее состав, в том числе доля кислорода в ее материи, должен был быть таким же, как у Солнца. Так это или нет, мы узнаем уже в ближайшее время, когда зонд Juno проведет первые аналогичные замеры, сблизившись с пятном в очередной раз.

Juno Captures Elusive 'Brown Barge'



A long, brown oval known as a "brown barge" in Jupiter's South Equatorial Belt is captured in this color-enhanced image from NASA's Juno spacecraft.

Brown barges are cyclonic regions that usually lie within Jupiter's dark North Equatorial Belt, although they are sometimes found in the similarly dark South Equatorial Belt as well. They can often be difficult to detect visually because their color blends in with the dark surroundings. At other times, as with this image, the dark belt material recedes, creating a lighter-colored background against which the brown barge is more conspicuous. Brown barges usually dissipate after the entire cloud belt undergoes an upheaval and reorganizes itself. Juno is giving us the first glimpses of the detailed structure within such a barge.

This image was taken at 6:26 p.m. PDT on Sept. 6, 2018 (9:26 p.m. EDT) as the spacecraft performed its 15th close flyby of Jupiter. At the time, Juno was 7,425 miles (11,950 kilometers) from the planet's cloud tops, above a southern latitude of approximately 22 degrees.

Jovian Close Encounter



A multitude of magnificent, swirling clouds in Jupiter's dynamic North North Temperate Belt is captured in this image from NASA's Juno spacecraft. Appearing in the scene are several bright-white "pop-up" clouds as well as an anticyclonic storm, known as a white oval.

This color-enhanced image was taken at 1:58 p.m. PDT on Oct. 29, 2018 (4:58 p.m. EDT) as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno was about 4,400 miles (7,000 kilometers) from the planet's cloud tops, at a latitude of approximately 40 degrees north.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft's JunoCam imager.

Снимок космического аппарата НАСА Юнона северного умеренного пояса Юпитера с изображением бури Большой белый овал

МОСКВА, 23 июл — РИА Новости. NASA опубликовало фотографию "закрученных" облаков сложной формы в Северном умеренном поясе Юпитера.

Кадр был сделан с помощью космического корабля Juno, который находился в 7000 километров от верхних слоев облаков.

Отмечается, что на снимке можно увидеть несколько ярких "всплывающих" образований, а также антициклоническую бурю — так называемый "Белый овал".

Спойлер

Juno был запущен в августе 2011 года для исследования Юпитера и вышел на его орбиту в июле 2016-го. В задачи миссии входит изучение гравитационного и магнитного полей планеты, а также проверка гипотезы о наличии у Юпитера твердого ядра.

Io Rising



Jupiter's moon Io rises just off the horizon of the gas giant planet in this image from NASA's Juno spacecraft. Slightly larger than Earth's moon, Io is the most volcanically active world in the solar system.

This color-enhanced image was taken at 2:26 p.m. PDT (5:56 p.m. EDT) on Oct. 29, 2018 as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno was about 11,400 miles (18,400 kilometers) from the planet's cloud tops, at approximately 32 degrees south latitude.

Citizen scientists Gerald Eichstädt and Justin Cowart created this image using data from the spacecraft's JunoCam imager. This image has been rotated approximately 155 degrees from the source image.
