UK’s £9 Million Bet on Jupiter’s Icy Moons
The UK Space Agency is making waves in space exploration with a £9 million investment in the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (JUICE). The mission includes one UK-funded science instrument and has seen UK contributions to two more, showcasing Britain’s cutting-edge space tech.
JUICE Ready for Launch: The Long Road to Jupiter
JUICE is set to blast off from Kourou, French Guiana, at 1.14pm on Friday 14 April. It will embark on an epic eight-year journey to the Jupiter system, using gravity assists from Earth and Venus to speed its way there. Once it arrives in 2031, the spacecraft will study Jupiter and its moons – Ganymede, Europa, and Callisto – with unprecedented detail.
Michelle Donelan, Secretary of State for Science, Innovation, and Technology, said:
“The UK Space Agency has invested approximately £9 million in the JUICE mission to investigate Jupiter and its moons. Our world-class science and research institutes are opening doors to deep space exploration.”
“I want the UK’s space sector to thrive and inspire the next generation in STEM. Pushing the boundaries of research and technology is essential for future jobs and innovation across the UK.”
Historic Mission: First Ever Orbit of a Moon Beyond Earth
JUICE’s grand finale will see it enter orbit around Ganymede in December 2034 – the first spacecraft ever to orbit a moon other than Earth’s. It will probe the vast ocean believed to lurk beneath Ganymede’s frozen shell, hunting for signs of habitability.
Dr Caroline Harper, UK Space Agency’s Head of Space Science, added:
“The launch marks years of global teamwork but the real adventure is just beginning. We’re eager to study Jupiter and its moons with top UK science instruments.
“Our researchers can’t wait to dig into the data that will help unlock mysteries of gas giants and icy moons, bringing us closer to understanding our Universe’s origins.”
UK Tech Powering JUICE Instruments
- J-MAG: A UK-led magnetometer developed by Imperial College London and partners, designed to probe magnetic fields around Jupiter and its moons.
- JANUS: An optical camera system led by Italy, but with UK-made imaging sensors from Teledyne-e2v, tested and calibrated by UK teams including the Open University.
- PEP: A particle environment package led by Sweden, with solid-state detectors from University College London and radiation design from Aberystwyth University.
Professor Michele Dougherty, Principal Investigator for J-MAG at Imperial College London, revealed:
“Our instrument lets us peer inside these worlds, but detecting signals is like hunting for needles in a constantly shifting haystack. It’s tough, but the potential discoveries are stunning.
“This launch is just the midway point – we first dreamed of this mission 15 years ago, and we’ll gather data for another 15 years. I can’t wait to kick off the next phase.”
Countdown and Collaboration
JUICE is a global effort featuring ESA, the UK, Japan, and Israel. After its launch aboard an Ariane 5 rocket, it will make 35 flybys of icy moons before orbiting Ganymede. Along the way, it will use Venus and Earth for gravity boosts and calibrations.
Experts across the UK are buzzing about the mission:
Chiaki Crews, Open University: “We’ve been fine-tuning JANUS’s image sensors to withstand harsh radiation expected near Jupiter. We’re excited for launch but know it’ll be years before the first moon snaps reach us.”
Prof Geraint Jones, University College London: “The PEP instrument will help us study the soup of particles around Jupiter that could be dangerous for astronauts. This data is key to understanding cosmic habitability.”
Prof Emma Bunce, University of Leicester: “JUICE pushes the boundaries in exploring potentially habitable worlds. We’re thrilled after years of work and awaiting groundbreaking data in 2031.”
Prof Manuel Grande, Aberystwyth University: “Our pioneering radiation shielding helps instruments survive Jupiter’s brutal environment and detect organic molecules near Europa, one of the best bets for extraterrestrial life.”
Daniel Waller, Teledyne e2v: “JUICE’s JANUS camera launch is a milestone. The sensor, made in Chelmsford, will capture stunning images of Jupiter’s frozen moons, deepening our solar system knowledge.”
