Jupiter antenna that got here in from the chilly

An instrument destined for Jupiter orbit is being checked after eight days of high-frequency cryogenic tests at ESA’s ESTEC technical center in the Netherlands.

The sub-millimeter wave instrument of the ESA Mission Juice will measure the turbulent atmosphere of Jupiter and the sparse atmospheres of its Galilean moons.

The tests took place in the specially made low-temperature near-field terahertz chamber from ESA or Lorentz.

As the first chamber of its kind, the Lorentz chamber with a diameter of 2.8 m can carry out high-frequency high-frequency tests under realistic space conditions and combines space-quality vacuum with ultra-low temperatures.

“The successful test of the flight hardware within Lorentz follows an intensive commissioning phase.” says ESA antenna engineer Paul Moseley. “This demonstration opens up a wide range of test options for upcoming missions.”

In the meantime, the flight model of the mother spacecraft Juice of the SWI-Instrument has reached the ESTEC test center in preparation for a month-long thermal vacuum test campaign.

Europe’s interior could be hot enough to heat volcanoes on the ocean floor

Pasadena CA (JPL) May 27, 2021

New research and computer models show that volcanic activity on the ocean floor of Jupiter’s moon Europa may have occurred in the recent past – and is possibly still occurring. NASA’s upcoming Europa Clipper mission, slated for launch in 2024, will fly near the icy moon and collect measurements that could shed light on the latest results. Scientists have strong evidence that Europe hosts a vast ocean between its icy crust and rocky interior. The new work shows how the moon is … read on
