We look forward to road testing some J-Mag flight sequences. 🙂
Today I could visit, thanks to Ignacio Tanco, the engineering model of @ESA_JUICE at the European Space Operations Centre @esaoperations . An impressive machine, whose "sister" is flying since almost one year towards Jupiter.
Our JUICE Magnetometer has now been fully and successfully tested, and we have good results, including the first ever measurement of the solar wind using a Quantum Interference Magnetic Sensor.

This is a map at the scale of 1 pixel to the diameter of the moon. It shows how far away Jupiter is, and why JUICE needs to go so fast, but still has a very long journey.

The first in-flight data from J-MAG. 👍
We’re pleased to share a first taste of #ESAJuice science data! 🤩
The magnetometer boom (J-MAG) recorded the change in magnetic field as it deployed.
J-MAG will help characterise Jupiter & Ganymede's magnetic fields, and the moons' oceans.

ALT A graph with magnetic field in nT on the y-axis and time in UTC on the x-axis. Two lines trace the data collected by two different sensors on the magnetometer boom. The lines are horizontal and one above the other in the first instance, before deployment of the boom. During and after the deployment the lines meet and trend towards zero.

A short news story about the launch of JUICE, it's journey to Jupiter, some of the science it will undertake, and the instruments that will achieve the science goals. There's even a short piece of footage of the J-MAG instrument in our lab. 🙂

JUICE has taken some selfies with its engineering cameras (the Juice Monitoring Cameras 1 and 2).

Deployment of both the very large solar panels was successful, and the spacecraft is now recharging the batteries that were used during the launch.
Checkout and commissioning of the spacecraft subsystems and scientific instruments, including J-MAG, will commence now.
Now we're waiting for acquisition of the spacecraft by the ground-station. This could be a while, depending on the exact orientation and status of the spacecraft.
What we're waiting for now, which will be a while, is deployment of the JUICE spacecraft from the second stage, when it has exhausted all its fuel.
The spacecraft is now over 2000 km along its journey, just below 200 km above the Earth, moving at over 7 km a second!
The next critical operation is separation of the first stage and firing of the engine on the second stage.
Four minutes into the flight, the solid rocket boosters have separated successfully, and the fairing has gone too. Everything nominal so far. 🙂
