Weekly Space Hangout: November 25, 2020, Dr. Olivier Witasse, Project Scientist, the JUICE Mission
This week we are airing Fraser's pre-recorded interview with Dr. Olivier Witasse, Project Scientist on the JUICE mission. Olivier studied fundamental physics and astrophysics at the universities of Paris XI (Orsay) and Lyon between 1990 and 1996. He obtained a PhD at the University of Grenoble in 2000. In 1995, he successfully completed the exams to become a teacher of Physics and Chemistry. He taught physics during his military service, and during his PhD at the university. He joined ESA as a staff member in 2003, after a two-year research fellowship at ESTEC and a four-month post doc at the Royal Observatory of Belgium. In 2015, Olivier joined the JUICE project. ****************************************

Exploring The Icy Moons of Jupiter. NASA's Europa Clipper and ESA's JUICE
Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System. But talk to planetary scientists, and they’re just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice. The perfect environment for life to thrive. We’ve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And they’re not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer. Our Book is out!

JUICE's Jovian odyssey
ESA's Jupiter Icy Moons Explorer, JUICE, 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. 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 circular 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. Even with the launch of JUICE a few years away, ESA is already planning for future exploration of the outer Solar System. NASA and ESA have been studying a possible joint mission that would target the two ice giant planets: Uranus and Neptune. As we discover more and more exoplanets around other stars, we find that many are gas giants in the size range of these gaseous worlds. Exploring our local planets to understand why our Solar System is the way it is, is critical to understanding exoplanet systems, too. The animation was prepared by Benjamin Torn as part of ESA's Young Graduate Trainee programme under the guidance of the JUICE project and with support from M. Stefko.

Juice’s journey to Jupiter
This animation shows the proposed trajectory of ESA’s Jupiter Icy Moons Explore (Juice) mission to Jupiter. Based on a launch in June 2022, the spacecraft will make a series of gravity-assist flybys at Earth (May 2023, September 2024 and November 2026), Venus (October 2023) and Mars (February 2025) before arriving in the Jupiter system in October 2029. The animation ends at the Jupiter orbit insertion point, but the planned 3.5 year mission will see Juice not only orbit Jupiter, but also make dedicated flybys of the moons Europa, Callisto and Ganymede, before orbiting the largest moon, Ganymede.

JUICE Space mission magnetometer boom
Iñaki Pinto, Aerospace Project Manager at SENER, explains at this video SENER’s role in the JUICE mission, where the company is developing the magnetometer boom. Jupiter Icy Moons Explorer (JUICE) is the most important program of the European Space Agency (ESA) to explore the Jovian system. SENER’s work in this contract consist of the design, manufacture, verification and integration of the magnetometer boom, the purpose of which is to place some of the instruments needed for scientific experiments away from the magnetic disturbances of the spacecraft.

JUICE - Exploring Jupiter’s icy Moons
In May 2022, the Airbus Defence and Space-built spacecraft JUICE (Jupiter Icy Moons Explorer) will head for Jupiter. Its main mission will be to explore the huge planet’s three largest icy moons in the hope of determining whether life is possible on these dwarf planets.
What if extra-terrestrial life does exist? For centuries, this question – which both fascinates and frightens mankind – has remained unanswered. But by the year 2030, some answers may well have been found – with the help of Airbus Defence and Space. In July 2015, the company was selected by the European Space Agency (ESA) as prime contractor for the design, development, production, and testing of a new spacecraft callednamed ‘JUICE’. As its name implies (Jupiter Icy Moons Explorer), the mission will be to explore the Jovian system, focussing on three of Jupiter’s huge Galilean moons: Europa, Ganymede and Callisto, which are as large as dwarf planets and covered by an icy crust.

European Space Agency "Juice" probe to Jupiter
The European Space Agency (Esa) is to mount a billion-euro mission to Jupiter and its icy moons. The probe, called Juice, has just been approved at a meeting of member state delegations in Paris. It would be built in time for a launch in 2022, although it would be a further eight years before it reached the Jovian system. http://www.bbc.co.uk/news/science-environment-17929133
