  • Juice takes the heat

    Juice takes the heat

    ESA’s Jupiter Icy moons Explorer, Juice, has successfully completed rigorous thermal tests simulating the extreme coldness of space and the warmth of the Sun at ESA’s test centre ESTEC, in The Netherlands.

    The spacecraft underwent a month of round-the-clock testing and monitoring in the Large Space Simulator, which recreates the vacuum of space and is able to simulate both hot and cold space environments. The spacecraft was subjected to temperatures ranging from 250 degrees to minus 180 degrees Celsius, showing that it can survive its journey in space.

    Juice will launch in 2022 to our Solar System’s largest planet. It will spend over four years studying Jupiter’s atmosphere, magnetosphere and its icy moons Europa, Callisto and Ganymede, investigating whether the moons’ subsurface oceans are habitable for life.

  • The making of Juice

    The making of Juice

    The ESA Jupiter Icy Moons Explorer (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.

  • Ultra-cool test of Jupiter instrument

    Ultra-cool test of Jupiter instrument

    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.

    ESA’s Solar Orbiter satellite in a cleanroom at the Astrotech payload processing facility near Kennedy Space Centre, Florida. The spacecraft is seen being mounted onto the payload adaptor ring and encapsulated into a fairing, which will protect the satellite and the rocket upper stage during the turbulent ascent through Earth’s atmosphere.
