ESA JUICE Mission

Excellent news, good to see that Juice is looking healthy and set for the long flight to Jupiter. :cool:

Bip bip ️ Three telescopes on Earth have begun monitoring radio signals from #ESAJuice.

The telescopes are part of Juice’s PRIDE experiment; they are being 'tuned up', ready for the spacecraft’s journey to and around Jupiter astron.nl/dailyimage/mai…

Here’s the evidence: a signal emitted by Juice at a frequency of about 8435.9 MHz (the spike in the centre of the main graph) was picked up by the Hobart, Yarragadee and Katherine telescopes in Australia with the strength and stability we expected (coloured lines in the inset).

These telescopes are part of the Earth-based PRIDE network – Juice’s Planetary Radio Interferometry and Doppler Experiment (PRIDE).

By combining signals received by radio telescopes around the world, PRIDE will measure Juice's position and velocity in space very precisely

PRIDE’s measurements will support Juice's onboard instruments.

They will also contribute to the mission’s scientific goals by telling us about the movement of Jupiter's icy moons and helping us get a clearer picture of what they look like and how they work

PRIDE is co-led by @jivevlbi and @tudelft, both based in the Netherlands

In total over 40 telescopes are involved, including the three in Australia operated by @UTAS_.

#ESAJuice is possible thanks to a huge international effort esa.int/ESA_Multimedia…

So how much fuel does Juice currently have considering the fact that it had a big burn? But it is good news that it is on track to arrive at Jupiter and Europa in 2031. Let's see if Juice has enough fuel left over to carry out the main mission.

ESA's Juice mission recently carried out one of the largest engine-powered manoeuvres in its 8-year journey to #Jupiter.

At #MissionControl, we often split large manoeuvres like this into two parts. That way, we can use the second, smaller manoeuvre to iron out any errors from the first.

But the first engine burn on 17 November was so accurate that no correction was necessary and the second, smaller burn was carried out smoothly on 1 December.

“It worked like a charm,” said @ESA_JUICE Spacecraft Operations Manager, Ignacio Tanco.

Juice is now on course to carry out the first-ever Earth-Moon double flyby in August 2024.

Juice’s lunar-Earth flyby: all you need to know

ESA’s Jupiter Icy Moons Explorer (Juice) will return to Earth on 19–20 August, with flight controllers guiding the spacecraft first past the Moon and then past Earth itself. This ‘braking’ manoeuvre will take Juice on a shortcut to Jupiter via Venus.

ESA’s Jupiter Icy Moons Explorer (Juice) is coming back to Earth.

29/07/2024

Our fearless traveller is getting a nudge from Earth this summer, in the first of four ‘gravity assist manoeuvres’ that will put Juice on precisely the right path to arrive at Jupiter with the correct speed and direction in July 2031.

This is the second big milestone in Juice’s journey to Jupiter, with the first being the launch into space on 14 April 2023. This second helping hand takes a very different form, with Juice flying past the Moon on 19 August, lining it up to fly past Earth on 20 August. The Earth flyby will line the spacecraft up for a flyby of Venus in summer 2025.

Gravity is a fickle friend. These gravity assist flybys are a valuable technique to get Juice to Jupiter with less fuel, but they threaten derailment at any time. ESA mission operators will be keeping a very close eye on the spacecraft as it approaches the Moon-Earth system, making any tiny adjustments needed to keep the spacecraft on the right course.

I wonder if the JUICE probe will take any photographs as it flybys the Moon and the Earth?
 
Let's wait and see NMaude, it would be a great idea for JUICE to fly by the Earth and the Moon to take photos. But I suppose it is all down to where JUICE will be in terms of where Earth and the Moon will be.
 
First views from Juice’s science camera

Since ESA’s Jupiter Icy Moons Explorer (Juice) flew by the Moon and Earth earlier this week, we’ve seen images from its monitoring cameras and we’ve seen images from its navigation camera. Today we reveal the first images from its scientific camera, JANUS, designed to take detailed, high-resolution photos of Jupiter and its icy moons.

JANUS will study global, regional and local features and processes on the moons, as well as map the clouds of Jupiter. It will have a resolution up to 2.4 m per pixel on Ganymede and about 10 km per pixel at Jupiter.

The main aim of JANUS’s observations during the lunar-Earth flyby was to evaluate how well the instrument is performing, not to make scientific measurements. For this reason, JANUS took images with various camera settings and time intervals – a bit like if you’re going out to test a DSLR camera for the first time.

In some cases, researchers intentionally ‘blurred’ the images so that they can test out resolution recovery algorithms. In other cases, they partially saturated the image to study the effects induced on the unsaturated areas.
