Juice Magnetometer

The Magnetometer on the Jupiter Icy Moons Explorer, JUICE.

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. 👍

[ESA's Juice mission @ESA_JUICE]

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.

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).

[Juice Magnetometer @j_magnetometer]

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.

[Juice Magnetometer @j_magnetometer]

The JUICE Spacecraft signal acquisition by the ground-station is successful! 👍😃

[Juice Magnetometer @j_magnetometer]

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.

Snapshots from the launch.

[Juice Magnetometer @j_magnetometer]

JUICE has separated from the upper stage, successfully. 😃

[Juice Magnetometer @j_magnetometer]

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.

[Juice Magnetometer @j_magnetometer]

The spacecraft is now over 2000 km along its journey, just below 200 km above the Earth, moving at over 7 km a second!

[Juice Magnetometer @j_magnetometer]

Successful second stage ignition. 😃 👍

[Juice Magnetometer @j_magnetometer]

The next critical operation is separation of the first stage and firing of the engine on the second stage.

[Juice Magnetometer @j_magnetometer]

Four minutes into the flight, the solid rocket boosters have separated successfully, and the fairing has gone too. Everything nominal so far. 🙂

[Juice Magnetometer @j_magnetometer]

Five minutes to launch, everything is green. 🚀 👍

Some of the Imperial College J-MAG Team are ready in Kourou for the launch, although the umbrellas are a less promising indicator of acceptable weather conditions today, than bright sunshine would be. 🙂
