The European probe visited Jupiter and its icy moons on April 14. As he moves away from our planet, Juice’s schedule is set to be very busy over the next few weeks. Shortly after takeoff, Juice revealed the first images of Earth.

[EN VIDÉO] Juice, a brilliant mission to unlock the secrets of Jupiter’s moons European probe JUICE departs on April 14, 2023 for Jupiter and its mysterious moons.
As a reminder, Joos is going to characterize the habitability and structure of several Galilean moons JovianJovian fully. It is a historic task that must meet new scientific objectives. After the takeoff pressurization, a new phase of the flight began, a very long one.
Role of surveillance cameras
It is very common for a planetary probe to send the first images very quickly. This is above all a sign of good health, and ensuring that the study performs as agreed after the turbulence of departure is critical to the mission. Visual confirmation is sometimes more reassuring than what it is TelemetryTelemetry of the study. Both JCM cameras deliver 1,024 square images For the footageFor the footage Next. The Juice also has a scientific camera that takes high-resolution images. ResolutionResolutionThis will be implemented in the coming weeks.
The Juice is equipped with two surveillance cameras. The first, JCM1, is installed at the front of the probe and tracks diagonally to view the antenna section and solar panels, the total surface of which reaches 85 m²! A second camera (JCM2) is installed above a the eyethe eye In a complex array of 16 meter long radar antenna (RIME). The reason is that Rhyme is Juice’s primary tool for his ability to see through the ice of moons.
What’s next in the program?
After the automatic deployment of solar panels, the operations center teamsESAESA (Esoc) took control of the study. ESA Operations Center teams will check all subsystems after launch to see if their operation is nominal. Indeed, if their ResistanceResistance Tested in a clean room, some items may be damaged vibrationsvibrations of RocketRocket During the flight.
Sequence of operations Contains multiple deployments. ” Juice is a very complex satellite. ” has also mentioned OlivierOlivier Vitesse, Extract Science Officer at ESA, Answers Futura’s questions. It started with a medium-gain antenna that could be used to communicate with Earth during interplanetary travel. Fifteen days are devoted to deploying the radar antenna, then the arm of the magnetometer (10 meters long), and finally three arms of 3 meters each with Langmuir probes at the end. Electric fieldElectric field and characterizes the ambient plasma.
Following this deployment phase, the “commissioning” phase begins, which, according to Oliver Vitass, will last until the end of June. At this stage, all subsystems, including science instruments, will be tested. ” There are ten instruments on the board, so it takes timeOlivier Witasse says. You should run them one after the other, verify that they work well, and test some monitoring methods. If we have time, we will take a picture of the earth with a camera [scientifique] “. It’s at the end of this phase that we can say the juice is in.” Survived the launch “.
More than a perfect departure
Again, as with the James-Webb Space Telescope, Ariadne 5Ariadne 5 did bull’s eye, In other words “Mile” in French! The details were revealed in a tweet by CEO Stephen IsraelArianespaceArianespace, show that no corrective manipulation is required. The stored fuel can be used later during the mission, especially for possible extension.
35 after 8 years of planetary travel FlyoversFlyovers Europa, Ganymede and CallistoCallistoThe juice will put itself inside Around the circular pathAround the circular path around Ganymede in 2034 and will remain there until September 2035. At the end of the mission there is a crash on the surface. But if enough fuel remains and the probe’s health permits, the mission could be extended and bring its orbit closer to 200 kilometers above the surface.
