ЦитироватьHubble observations reveal ocean on Ganymede

Scientists using the Hubble Space Telescope have found the best evidence yet of a salty ocean of liquid water lurking beneath the surface of Jupiter's largest moon Ganymede, ripening the icy world's allure as mission planners design probes for more detailed exploration.
Long thought to possess an underground ocean, Ganymede is the largest moon in the solar system and measures bigger than Mercury.
Researchers studied the oscillation of auroral belts near Ganymede's north and south poles with Hubble to conclude a substantial reservoir of liquid water must exist beneath the moon's icy crust.
"Our new HST observations provide the best evidence to date for the existence of an ocean on Ganymede," said Joachim Saur, professor of geophysics at the University of Cologne in Germany.
Ganymede is the only only moon in the solar system with its own magnetic field, triggering belts of polar aurorae similar to the northern and southern lights on Earth.
"If someone could be standing on Ganymede looking up into the night sky, it would appear as red aurora to you, and it would be visible even with the naked eye," Saur said Thursday in a teleconference with reporters.
The magnetic field of Ganymede also interacts with Jupiter's powerful magnetism, causing the belts to shift in latitude. Saur's science team won prized observing time with Hubble to measure how much the auroral belts oscillate over time.
"This is a really great example of using a remote sensing technique — using a telescope in orbit around the Earth — to study a moon that's in orbit around Jupiter and yet be able to make inferences about the interior of that moon just by looking at it from the outside," said Heidi Hammel, executive vice president of the Association of Universities for Research in Astronomy. "We aren't at Jupiter. Hubble is at the Earth, and yet it can probe the internal structure of this moon remotely. That's a really powerful tool."
It turns out the volume of water persisting beneath Ganymede's surface has an influence on the aurorae, counteracting the tug from Jupiter that would cause the belts to "rock" up to 6 degrees back and forth every 10 hours.
"However, when there is a salty, and thus electrically-conducting ocean present, this ocean counterbalances Jupiter's magnetic field influence and reduces the rocking of the aurora to only 2 degrees," Saur said.

"We used HST (and) looked at Ganymede for more than five hours, and monitored the aurorae and saw that the aurorae barely moved during that five hours — only rocking by 2 degrees — exactly like (we) predicted when there is an ocean present," Saur said. "This confirms the existence of an ocean and simultaneously it rules out the absence of an ocean."
Scientists believe Ganymede's buried ocean has more water than all the water on Earth's surface, perhaps measuring as much as 60 miles thick underneath a 95-mile crust of mostly ice, according to a NASA press release.
"This discovery marks a significant milestone, highlighting what only Hubble can accomplish," said John Grunsfeld, associate administrator of NASA's science mission directorate. "In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth."
According to Saur, the team based in Cologne used Hubble on two occasions in 2010 and 2011 to monitor the movement of aurorae in ultraviolet light, simultaneously observing Ganymede's northern and southern belts.
"We have four independent measurements, and all four measurements show that the aurorae in all these cases moved by 2 degrees only, and this gives us confidence in the measurement," Saur said.
NASA will celebrate the 25th anniversary of Hubble's launch in April, and officials are confident the storied observatory will continue operating into the 2020s after repairs by astronauts on a series of space shuttle missions, most recently in 2009.
"Hubble is the only observatory right now that can do these kind of observations in ultraviolet light, and be able to precisely resolve and disinctly detect these features on Ganymede," said Jennifer Wiseman, NASA Hubble senior project scientist.
NASA's Galileo spacecraft orbited Jupiter from 1995 to 2003, flying by the giant planet's moons to snap photos, study their geology and measure their composition. Galileo conducted six flybys of Ganymede, finding evidence that part of the moon's surface had been flooded from water eruptions through ice volcanoes.
"Based on the geology, we believe there was a time when the ocean may have communicated with the surface in the distant past," said Jim Green, director of NASA's planetary science division.
"Since the 1970s, there was speculation and models that Ganymede could possess an ocean," Saur said. "However, there was only one (piece of) observational evidence, and that comes from the Galileo orbiter. Galileo had six close flybys of Ganymede, but these flybys lasted only 20 minutes each. That's too short to resolve the effects of the ocean without ambiguity ... The new trick with the Hubble observation is that we have seven hours of data, and then we do not have this ambiguity any more."

The European Space Agency plans to launch a probe to Jupiter in June 2022 for the most in-depth study of Ganymede yet.
Arriving at the gas giant in January 2030, the Jupiter Icy Moons Explorer will zip past Jupiter's moons Europa and Callisto, each believed to contain subterranean oceans, multiple times before settling into orbit around Ganymede for nearly 10 months.
NASA is working on a separate mission for launch in the 2020s to focus on Europa, and the space agencies could partner to build instruments and secondary payloads to accompany each spacecraft on the journey.
ESA's JUICE mission and NASA's Europa flyby probe — successors to the Galileo orbiter — could be flying through the Jupiter system at the same time in the 2030s.
"When the JUICE mission ultimately goes into orbit around Ganymede, it will have a very, very rich and exciting science mission," Hammel said.

Airbus To Build ESA's Jupiter-bound Juice Orbiter
http://spacenews.com/airbus-to-build-esas-jupiter-bound-juice-orbiter/

ЦитироватьPARIS — The European Space Agency on July 16 sel ected Airbus Defence and Space to build Europe's Juice orbiter, to be launched in 2022 aboard a European Ariane 5 rocket and to arrive at the Jupiter system in 2030.

The contract, for 350.8 million euros ($389 million) was approved by ESA's Industrial Policy Committee and will be signed by ESA and Airbus in September. The Ariane 5 launch will be contracted separately by ESA.

Спойлер
Airbus bested a team composed of Thales Alenia Space of France and Italy and OHB SE of Germany, a frequent pairing for ESA competitions because it fills a hole in each company's production-site premises.

ESA science missions are funded by mandatory contributions from the agency's 22 member states, based on national gross domestic product. ESA's geographic return rules mean work-share distribution must closely match each nation's financial input, meaning Germany, France, Britain and Italy, as ESA's biggest members, must be guarantee major pro rata roles for their domestic industry.

Airbus has major operations in France, Germany, Britain and Spain. Thales Alenia Space is focused on France and Italy, and OHB's main facilities are in Germany.

With some exceptions, ESA's member states finance science missions on their own, often with contributions from nations outside ESA. Juice will carry 10 instruments coming from 16 ESA members, and also fr om the United States and Japan.

The trajectory to Jupiter will include gravity-assist flybys of the Callisto and Ganymede moons, and two close-in flybys of the Europa moon. At the end of the mission, Juice is expected to spend eight months dedicated to the study of Ganymede.

Ну, и то же по-русски
 Выбран генподрядчик на строительство зонда для полета на Юпитер

ЦитироватьСогласно официальному сообщению представителей ЕКА журналистам The Independent, генеральным подрядчиком на строительстве зонда станет компания Airbus Defence and Space, являющаяся подразделением Airbus Group, известной, прежде всего, своими самолетами. Сообщается, что подрядчик должен будет заняться строительством космического аппарата уже через несколько дней.

Спутники Юпитера, такие, как Европа, являются одними из наиболее вероятных мест в Солнечной системе, где может находиться внеземная жизнь. Именно для того, чтобы ответить на данный вопрос и постараться найти следы существования живых организмов на Европе, Каллисто и Ганимеде и создается зонд JUpiter ICy moons Explorer или просто JUICE.

Автоматическая исследовательская станция должна будет стартовать по направлению к Юпитеру, и в 2030 году достигнет спутников крупнейшей планеты Солнечной системы. Целью исследований Европы, Ганимеда и Каллисто, по словам представителей ЕКА, будет попытка выявить существование жизни в их подледных океанах.

Крупнейший из спутников, который будет исследовать зонд JUICE, Ганимед, как и спутник Сатурна Титан превосходит по своим размерам планету Меркурий. Как считают некоторые ученые, под ледяными поверхностями данных галилеевых спутников могут скрываться колоссальные по объемам воды океаны.

Unlocking the secrets of the Jupiter's Icy Moons
http://youtu.be/NrkF5beDh10

ЦитироватьIn this edition of Space we set a course for Jupiter, destination of the next European Space Agency mission.

The aim of JUICE (JUpiter ICy moon Explorer) is to provide the most comprehensive exploration of the giant planet and, in particular, of its moons; supposedly hiding habitable zones under their icy crusts.

Jupiter is more than eleven times larger than Earth but is mainly made of gas. During its three and a half year mission, which blasts off in 2022, JUICE will travel around the giant planet, studying its atmosphere and three of its planet-sized satellites: Ganymede, Europa, and Callisto.

Jupiter mission contract ceremony
http://www.esa.int/spaceinimages/Images/2015/12/Jupiter_mission_contract_ceremony

ЦитироватьESA and Airbus Defence & Space today marked the signing of the contract for building Juice, the JUpiter ICy moons Explorer.

The mission was sel ected in May 2012 as the first Large-class mission within ESA's Cosmic Vision 2015–25 programme, and is planned for launch in 2022 to arrive at the giant planet in 2030.

For three and a half years, Juice will sweep around Jupiter, exploring its turbulent atmosphere, enormous magnetosphere and tenuous set of dark rings, as well as studying the icy moons Ganymede, Europa and Callisto. It will eventually go into orbit around Ganymede, a first in Solar System exploration.

All three of these planet-sized satellites are thought to have oceans of liquid water beneath their icy crusts and should provide clues on the potential for such moons to offer habitable environments.

Airbus Defence & Space SAS in France was announced as the prime contractor in July when ESA approved the €350 million contract.

The contract covers the design, development, integration, test, launch campaign and in-space commissioning of the spacecraft. The Ariane 5 launch is not included and will be procured later fr om Arianespace.

The 10 state-of-the-art instruments were approved by ESA in February 2013 and are being developed by teams spanning 16 European countries, the USA and Japan, under national funding.

The spacecraft will be assembled at Airbus Defence and Space GmbH in Friedrichshafen, Germany.

ESA's Jupiter mission moves off the drawing board

ЦитироватьDemanding electric, magnetic and power requirements, harsh radiation, and strict planetary protection rules are some of the critical issues that had to be tackled in order to move ESA's Jupiter Icy Moons Explorer – Juice – from the drawing board and into construction.

Спойлер
Scheduled for launch in 2022, with arrival in the Jovian system in 2029, Juice will spend three-and-a-half years examining the giant planet's turbulent atmosphere, enormous magnetosphere, its set of tenuous dark rings and its satellites.

It will study the large icy moons Ganymede, Europa and Callisto, which are thought to have oceans of liquid water beneath their icy crusts – perhaps even harbouring habitable environments.

The mission will culminate in a dedicated, eight-month tour around Ganymede, the first time any moon beyond our own has been orbited by a spacecraft.

Juice will be equipped with 10 state-of-the-art instruments, including cameras, an ice-penetrating radar, an altimeter, radio-science experiments, and sensors to monitor the magnetic fields and charged particles in the Jovian system.

In order to ensure it can address these goals in the challenging Jovian environment, the spacecraft's design has to meet stringent requirements.
[свернуть]
An important milestone was reached earlier this month, when the preliminary design of Juice and its interfaces with the scientific instruments and the ground stations were fixed, which will now allow a prototype spacecraft to be built for rigorous testing.

The review also confirmed that the 5.3 tonne spacecraft will be compatible with its Ariane 5 launcher.

Спойлер
Operating in the outer Solar System, far from the Sun, means that Juice needs a large solar array: two wings of five panels each are foreseen, which will cover a total surface area of nearly 100 sq m, capable of providing 820 W at Jupiter by the end of the mission.

After launch, Juice will make five gravity-assist flybys in total: one each at Mars and Venus, and three at Earth, to set it on course for Jupiter. Its solar panels will have to cope with a range of temperatures such that when it is flying closer to the Sun during the Venus flyby, the solar wings will be tilted to avoid excessive temperatures damaging the solar cells.

The spacecraft's main engine will be used to enter orbit around the giant planet, and later around Jupiter's largest moon, Ganymede. As such, the engine design has also been critically reviewed at this stage.

Special measures will allow Juice to cope with the extremely harsh radiation that it must endure for several years around Jupiter. This means careful selection of components and materials, as well as radiation shielding.

ЦитироватьJuice's Jovian odyssey

European Space Agency, ESA

Опубликовано: 6 февр. 2019 г.

Juice, ESA's Jupiter Icy Moons Explorer, is set to embark on a seven-year cruise to Jupiter starting May 2022. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for the numerous giant planets now known to orbit other stars.

This animation depicts the journey to Jupiter and the highlights from its foreseen tour of the giant planet and its large ocean-bearing moons.
Спойлер
An Ariane 5 will lift Juice into space from Europe's Spaceport in Kourou. A series of gravity-assist flybys at Earth (3), Venus (1) and Mars (1) will set the spacecraft on course for its October 2029 rendezvous in the Jovian system.

It is expected that a number of instruments will be activated during the gravity assists (indicated by the different coloured beams scanning across the planets) and measurements will be taken for calibration and to check the health of the instruments. The visualisations of the Earth flybys show the closest approaches over the planet according to current planning – over the South Pacific Ocean, Argentina and Peru, respectively. Throughout the animation, the instrument beam colours correspond to example observations by JANUS (green), MAJIS (red), UVS (purple), Gala (Blue) and RIME (grey), which are cameras, spectrometers, laser altimeter and radar.

During the Venus flyby, limited observations can be made because the spacecraft will be oriented to protect it from the heat of the Sun experienced in the inner Solar System. The Mars flyby will see Juice fly over the planet's south pole to make scientific observations.

Juice will start its science mission about six months prior to arriving in orbit around the gas giant, making observations as it approaches its destination. Once in the Jovian system, a gravity-assist flyby of Jupiter's largest moon Ganymede – the largest moon in the Solar System – helps Juice enter orbit around the gas giant 7.5 hours later.

While in Jupiter orbit, the spacecraft will study the Jovian system as an archetype for gas giants, making observations of its atmosphere, the magnetosphere, its rings and satellites.

During the tour, Juice will make two flybys of Europa, which has strong evidence for an ocean of liquid water under its icy shell. Juice will look at the moon's active zones, its surface composition and geology, search for pockets of liquid water under the surface and study the plasma environment around Europa.

A sequence of Callisto flybys will not only be used to study this ancient, cratered world that may too harbor a subsurface ocean, but it will change the angle of Juice's orbit with respect to Jupiter's equator, making it possible to investigate the polar regions and environment at higher latitudes.

During the tour there will also be unique periods to observe events such as moon transits. The example in this animation shows Europa and Io passing in front of Jupiter on 27 January 2032. This type of event is rare, with less than 10 expected to occur during Juice's tour of the Jovian system.

A sequence of Ganymede and Callisto flybys will adjust the orbit of Juice to enable it to enter orbit around Ganymede, marking it the first spacecraft to orbit another planet's moon (aside from our own). The elliptical orbit will be followed by a 5000 km altitude cicular orbit, and later a 500 km circular orbit.

Ganymede is unique in the Solar System in that it is the only moon to have a magnetosphere. Juice will investigate this phenomenon and the moon's internal magnetic field, and the interaction of its plasma environment with that of Jupiter. Juice will also study the moon's atmosphere, surface, subsurface, interior and its internal ocean, investigating the moon as a planetary object and possible habitat.

Over time the 500 km orbit will naturally decay – eventually there will not be enough propellant to maintain it – and it will make a grazing impact on the surface. The animation concludes with an example of what the approach to impact could look like.
