Jupiter antenna that came in from the cold

Jupiter antenna that came in from the cold

“An instrument destined for Jupiter orbit is checked after completing eight days of cryogenic radio-frequency testing at ESA’s ESTEC technical centre in the Netherlands.
The Sub-millimetre 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.
“The successful test of the flight hardware inside Lorentz, follows an intensive commissioning phase.” says ESA antenna engineer Paul Moseley. “This demonstration opens up a wide range of testing possibilities for missions to come.”
Meanwhile the flight model of the SWI instrument’s parent Juice spacecraft has itself reached the ESTEC Test Centre, in preparation for a month long thermal vacuum test campaign.”
