” It is thanks to the management of ESA and the effort and dedication of numerous European industries and scientific organizations that the Juice mission has ended up being a truth,” states Giuseppe Sarri, ESAs Juice Project Manager. “Together with our partners NASA, the Japan Aerospace Exploration Agency, and the Israel Space Agency, who have likewise contributed hardware or scientific instrumentation, we have reached this much-awaited launch milestone.”
From Galileo to Juice
Jupiter, shining brilliantly in the night sky, has actually sparked fascination since our ancient forefathers initially searched for. Astronomer Galileo Galilei brought Jupiter into focus in 1610, observing the planet through a telescope for the very first time and discovering its orbiting moons. His observations reversed the long-held concept that whatever in the paradises revolved around Earth. Centuries later, Juice– which carries a commemorative plaque in honor of Galileos discoveries– will see Jupiter and its moons in a manner that Galileo could not even have actually dreamt of.

Thanks to the legacy of previous Jupiter missions (see infographic listed below) we know that three of the worlds largest moons– Europa, Ganymede, and Callisto– hold quantities of water buried under their surfaces in volumes far higher than in Earths oceans. These planet-sized moons provide us enticing hints that conditions for life might exist besides here on our pale blue dot, and Juice is geared up to bring us one action closer to addressing this alluring question.
On the right of the timeline are spacecraft that have actually flown by Jupiter on their way to the more remote reaches of the Solar System; the mentioned dates show the year that the spacecraft flew past the gas giant.ESAs Jupiter Icy Moons Explorer (Juice) objective introduced on April 14, 2023, to make comprehensive observations of the huge gas world and its three big ocean-bearing moons– Ganymede, Callisto and Europa– with a suite of remote picking up, geophysical and in situ instruments. Juice will identify these moons as both possible environments and planetary objects, explore Jupiters complex environment in depth, and study the wider Jupiter system as an archetype for gas giants throughout the Universe.The first individual to view Jupiter and its biggest moons through a telescope was Galileo Galilei in 1609.
” Over 400 years earlier, Galileo discovered moons orbiting Jupiter– news that shocked the Renaissance world and revolutionized mankinds understanding of our location in the Universe,” says Carole Mundell, ESAs Director of Science. “Today, we have actually sent a suite of ground-breaking science instruments on a journey to those moons that will provide us a beautiful close-up view that would have been inconceivable to previous generations. Juice brings the dreams of anyone whos ever gazed up at Jupiter shining brilliantly in the night sky and questioned about our origins.
” The gold mine of information that ESA Juice will supply will enable the science neighborhood worldwide to dig in and uncover the secrets of the jovian system, check out the nature and habitability of oceans on other worlds, and address questions yet unasked by future generations of scientists.”
Mankinds next strong objective to the external Solar System, ESAs Jupiter Icy Moons Explorer, Juice, is poised to explore the huge planet Jupiter and its biggest moons. These interesting worlds have actually stimulated our curiosity ever given that Galileo first raised his telescope to the planet and discovered its four largest moons: Io, Europa, Ganymede, and Callisto, three of which are believed to harbor underground oceans.
Journey to Jupiter
Juice is the last ESA area science objective to launch on an Ariane 5, in a long tradition (see infographic below) going back to 1999 with the launch of XMM-Newton, which is still in operation today, and most just recently, the NASA/ESA/CSA James Webb Space Telescope in 2021.
” What a splendid demonstration of Europes capacity to dream huge and deliver results to match,” states Daniel Neuenschwander, ESAs Director of Space Transportation. “We can all be happy of Ariane 5 for making possible missions like Juice and setting such a high standard for our brand-new generation of launch systems.”
ESAs Ariane 5, manufactured by ArianeGroup, has been in operation considering that 1996 and has actually already finished more than 100 launches from Europes Spaceport in French Guiana. It is 53 m high and 5.4 m in diameter with a liftoff mass of 780 tonnes.The Jupiter Icy Moons Explorer (Juice) will be the last ESA mission to introduce on an Ariane 5 before Ariane 6 takes control of.

Over the next two-and-half weeks (see infographic listed below) Juice will deploy its numerous antennas and instrument booms, including the 16 m long radar antenna, 10.6 m long magnetometer boom, and different other instruments that will study the environment of Jupiter and the subsurface of the icy moons.
An eight-year cruise with four gravity-assist flybys at Earth and Venus will slingshot the spacecraft toward the external Solar System. The first flyby in April 2024 will mark an area expedition initially: Juice will carry out a lunar-Earth gravity-assist– a flyby of the Moon followed 1.5 days later on by one of Earth.
ESAs Jupiter Icy Moons Explorer (Juice) will launch in April 2023 from Europes Spaceport in Kourou, French Guiana, on an Ariane 5 launcher. In between 99 minutes and 17 days post launch, Juices solar arrays, antennas, probes, and magnetometer boom will be released, after which Juice is ready to continue its eight-year journey to Jupiter.
ESAs spacecraft operators, technology engineers, and mission analysts have actually worked extensively to get ready for the challenges that lie ahead on this adventurous objective.
Shields will safeguard the spacecrafts sensitive electronics from the monstrous levels of radiation in the Jupiter system. Multi-layered insulation will keep internal temperature levels steady while externally they might reach more than 250ºC throughout the Venus flyby and -230 ºC at Jupiter.
ESAs Jupiter Icy Moons Explorer (Juice) is set to embark on an eight-year cruise to Jupiter starting in April 2023. It will reach Jupiter in July 2031, but will already start making scientific observations 6 months prior to going into orbit around Jupiter.
” Hundreds of millions of kilometers from Earth and powered by simply a sliver of sunlight, we will guide Juice through 35 flybys of Jupiters ocean moons in order to gather the information required to bring scientists closer than ever to these compelling locations,” states Ignacio Tanco, ESAs Juice spacecraft operations manager.
” To fly such a complicated path from such an enormous distance– and extremely, to get Juices valuable information home to Earth– will require exact navigation strategies, reliant on ESAs deep area antennas in Spain, Argentina and Australia, all controlled from another location from ESOC.”
Creating a spacecraft for a trip to the external Solar System is no easy accomplishment. The Jupiter Icy Moons Explorer (Juice) will have to handle challenges like low and extremely high temperature levels, a lack of sunshine at Jupiter, and high levels of radiation around Jupiter.Juice has actually been specially developed to overcome all these difficulties and numerous more. For instance, guards have actually been built to protect the spacecrafts sensitive electronic devices, large solar panels will allow it to gather great deals of sunshine, Multi-Layer Insulation will keep it at a steady temperature level, a big antenna will assist it interact with engineers on Earth, and an effective onboard computer system– Juices brain– will help it to solve some problems separately, without requiring to call Earth at all.Credit: ESA (Acknowledgment: work carried out by ATG under agreement to ESA), CC BY-SA 3.0 IGO
” We are ready to steer among the most intricate missions ESA has ever flown to experiences in the jovian system,” states Angela Dietz, deputy spacecraft operations supervisor. “From flybys of Jupiters moons over a duration of two-and-a-half years, to the immense obstacle of switching orbits from massive Jupiter to orbiting Ganymede, well be solving obstacles at mission control that have never been done before.”

Ganymede, which is bigger than the planet Mercury, is Juices main scientific target; it will spend around nine months observing the moon closely from orbit. Ganymede has an especially appealing particular besides its surprise ocean: it is the only moon in the Solar System to produce its own electromagnetic field. Just 2 other strong bodies produce a field like Ganymedes– Mercury and Earth.
The result is a small magnetic bubble sitting within Jupiters bigger one, and the 2 connect in extremely complex ways. Juice will reveal more about the interior structure of Ganymede and in doing so will be able to determine how its core has the ability to generate and maintain an electromagnetic field. This will be essential to comprehending how the moon evolved, and the effects for habitability.
This animation shows the interior structure of Jupiters moon Ganymede. Ganymede is thought to host subsurface liquid oceans that will be explored in detail by ESAs Jupiter Icy Moons Explorer (Juice). It is the only moon in the Solar System to produce its own magnetic field, which has complicated interactions with Jupiters own huge magnetic field, and Juice will study the relationship in between the two.Understanding the state of the moons interior, and in particular, if it hosts liquid water, will help answer essential questions about the habitability potential of the moon, and of similar exoplanet systems somewhere else in our Universe.Credit: ESA/ATG Medialab
Ganymede likewise shows a vast array of surface ages and functions, using a geological record covering a number of billion years. This matches its brother or sisters– ancient Callisto, which may hold hints to early conditions in the jovian system, and young and active Europa, which vents water into space.
” The scientific treasure that will be returned will unquestionably have significant ramifications on how we understand our Solar System and if there are possibly habitable areas beyond Earth– not just in our own cosmic area however also well beyond in the huge number of exoplanet systems populating our Universe,” states Olivier Witasse, ESAs Juice project scientist. “In turn, this understanding will make us richer beings, finding out more about ourselves, our origins, and our place in deep space.”
Juice will make comprehensive observations of the giant gas planet and its three big ocean-bearing moons– Ganymede, Callisto, and Europa– with a suite of instruments. The mission will likewise explore Jupiters complex environment in depth, and study the wider Jupiter system as an archetype for gas giants throughout the Universe.
