News! The radar that will study Jupiter's moons has just entered the testing phase. Recently, ESA confirmed that tests are being done for the radar that will study the months of Jupiter. So far, ESA's tests are on a 1:18 scale spacecraft model. This spacecraft that will study the months of Jupiter is called the Juice, and ESA is the main space agency designing it. 

This model, which has been tested, is used to test its radar antenna and see how it works. According to ESA, the spacecraft will be able to probe up to 9 km deep in the Gallic months (Io, Europa, Ganymede and Calisto) of Jupiter. Athens will also be very useful in this process, so it has been tested among the first. In any case, in order to test the real spacecraft in size, the ship will have to be prepared and this will take some time. But so far it is known that the tests were performed at Hertz (Hybrid European RF and Antenna Test Zone) based at ESA's ESTEC technical center in the Netherlands. 

The European space agency explained that according to tests, projects and a lot of research, the metal walls shield the radio signals from outside the ship. In addition, the sharp plating of the ship with sharp foam can very well absorb radio signals from the outside to the inside. This primarily helps to create conditions that simulate the infinite void of space. These things were published in a post by ESA. 

The room where the ship was tested, in the Hetrz room, is one of the few "hybrid" rooms. This test chamber tested this new ship was tested on the basis of the local "near field", to evaluate the radio signals from the antenna, but also in addition to the local one, it is also those from thousands of km. distance in space. Through the local one, the ship can have radio signals around it in a rather small radius. And the one of thousands of km. it means a very wide range, including up to some satellites.

We wish success to ESA and all those who work together to build this spacecraft.
