\nA view of the Juice thermal development model inside the Large Space Simulator at ESA’s technical heart in the Netherlands.\n<\/p>\n

\nJuice, or the Jupiter Icy Moon Explorer, is ESA’s future mission to explore the Solar System’s largest planet and its ocean-bearing moons. Planned for launch in June 2022, it will embark on a seven year cruise that will make use of several flybys \u2013 of Earth, Venus, Earth, Mars, and again Earth \u2013 before leaving the inner Solar System for Jupiter.\n<\/p>\n

\nIn order to ensure that the spacecraft will survive the extreme temperature variations it will experience along the journey, a thermal verification test was completed in May 2018.\n<\/p>\n

\nThe spacecraft model, wrapped in multi-layer insulation, is visible in the foreground, while the high-energy lamps and mirrors of the Sun simulator can be seen in the upper part of the frame. The Sun simulator was used to heat the Sun-facing side of the spacecraft model to around 200\u00baC. Meanwhile the internal temperature of the vacuum chamber was lowered to -180\u00baC by thermal shrouds filled with liquid nitrogen to reproduce the cold conditions of the sides that will face away from the Sun.\n<\/p>\n

\nThis hot phase was followed by the cold phase, which simulated the low-temperature environment at Jupiter by maintaining the frigid conditions inside the chamber and switching off the Sun simulation lamps.\n<\/p>\n
