“Our Jupiter Icy Moons Explorer, Juice, will make detailed observations of the giant gas planet and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. The mission will characterise these moons as both planetary objects and possible habitats, explore Jupiter’s complex environment in depth, and study the wider Jupiter system as an archetype for gas giants across the Universe.
Juliet will be taking us to Jupiter and its moons in the coming weeks. So stay tuned for more!”

„After many years of study, development, building and testing, ESA’s Jupiter Icy Moons Explorer, Juice, has finally arrived at Europe’s Spaceport in Kourou, French Guiana. At the end of 2022 the spacecraft underwent its final thermal vacuum test at an Airbus Defence and Space facility in Toulouse, as well as its final software verification tests, whereby it was controlled from the ESOC mission control centre in Darmstadt, Germany.
Soon, an Ariane 5 will lift Juice into orbit and send it on its journey to explore the largest planet in our Solar System and its three icy moons, Europa, Callisto and in particular Ganymede. By exploring and studying the Jovian system, the mission neatly fullfills its role in ESA’s Cosmic Vision programme, teaching us about our Universe and the origins of life.“

„ESA’s Jupiter Icy Moons Explorer, Juice, has an ambitious mission ahead. Juice will observe Jupiter and its three largest moons: Callisto, Europa, and in particular Ganymede. The moons’ buried oceans could tell us whether life can arise in different environments across the cosmos. 
Juice will examine Jupiter and its complex environment to transform our understanding of how the planet works. Its discoveries may also shed new light on solar system evolution, both in our home system and in the diverse array of exoplanet systems beyond our own. Juice will launch on an Ariane 5 from Europe’s Spaceport in Kourou, French Guiana. It will journey for eight years before starting its complex manoeuvres in the Jupiter system making 35 flybys of Europa, Ganymede and Callisto before orbiting Ganymede.
This grand odyssey of exploration begins in April 2023.“

„An instrument destined for Jupiter orbit undergoes eight days of cryogenic radio-frequency testing using a new test facility at ESA’s ESTEC technical centre in the Netherlands. The Submillimetre Wave Instrument of ESA’s Juice mission will survey the churning atmosphere of Jupiter and the scanty atmospheres of its Galilean moons.
Testing took place in ESA’s custom-built Low-temperature Near-field Terahertz chamber, or Lorentz. The first chamber of its kind, the 2.8-m diameter Lorentz chamber can perform high-frequency radio-frequency testing in realistic space conditions, combining space-quality vacuum with ultra-low temperatures.“

This first episode of ‘The journey of Juice’ tells the story of Juice’s first months in space, from its launch on 14 April 2023 to its lunar-Earth gravity assist (LEGA for short) in August 2024.

„...This episode focuses on the geophysics instruments, which will explore the moons’ surface and subsurface, probe the atmospheres of Jupiter and its moons, and measure their gravity fields.
The GAnymede Laser Altimeter (GALA) will study the tidal deformation of Ganymede and the topography of the surfaces of the icy moons. The Radar for Icy Moons Exploration (RIME), is an ice-penetrating radar to study the subsurface structure of the icy moons down to a depth of around nine kilometres. The Gravity & Geophysics of Jupiter and Galilean Moons (3GM), is a radio package that will study the gravity field at Ganymede, the extent of the internal oceans on the icy moons, and the structure of the neutral atmosphere and ionosphere of Jupiter and its moons.

The mission will also carry out a Planetary Radio Interferometer & Doppler Experiment (PRIDE), which will use the standard telecommunication system of the spacecraft, together with radio telescopes on Earth to perform precise measurements of the spacecraft position and velocity to investigate the gravity fields of Jupiter and the icy moons.
The documentary includes interviews with (in order of appearance): Olivier Grasset, Juice interdisciplinary scientist, Luciano Iess, 3GM principal investigator, Hauke Hussmann, GALA principal investigator, Lorenzo Bruzzone, RIME principal investigator, Leonid Gurvits, PRIDE principal investigator.“

„The ESA Juice team has been working very hard to prepare the spacecraft for the first test in the one-year long environmental test campaign. This is the so-called Thermal Balance Thermal Vacuum (TBTV) test.
Juice is in the Large Space Simulator (LSS), a unique facility in Europe (run by the European Test Center, at ESA/ESTEC in the Netherlands) that can simulate the vacuum and cold and hot temperature conditions in space, and also the Sun itself!
The TBTV started on 17 June with the closure of the LSS and the "pumping-down", meaning the removal of air within the chamber to a pressure level of 10nbar (1/100 000 000th of the outside air pressure). This is the closest Juice will come to space conditions while on Earth. It will undergo 24/7 testing, ending on 16 July 2021.
In this episode this process is followed and several team members comment on the different moments.“

„JUICE has been finished!! Well, the integration of the spacecraft has been finished to a very large degree by the people at Airbus Friedrichshafen, Germany, and all the project team.
