ESA’s Jupiter Icy Moons Explorer ( https://www.esa.int/Science_Exploration/Space_Science/Juice ), is on an epic eight-year journey to Jupiter. This first episode of ‘The journey of Juice’ tells the story of Juice’s first months in space, from its launch on 14 April 2023 to its lunar-Earth gravity assist (LEGA for short, see https://www.esa.int/Science_Exploration/Space_Science/Juice/Juice_rerouted_to_Venus_in_world_s_first_lunar-Earth_flyby.) in August 2024. This flyby was not only the first double gravity assist manoeuvre of its kind, it was also a perfect opportunity to test out the spacecraft’s cameras and science instruments.
In this episode, Juice’s Mission Manager Nicolas Altobelli explains how the spacecraft will become the first ever human-made machine to orbit a moon of another planet, in this case Jupiter’s largest moon Ganymede.
You’ll also hear from Claire Vallat and Marc Costa at the European Space Astronomy Centre (ESAC) near Madrid, Spain. Juice will perform incredibly complex measurements once it reaches Jupiter, and the Science Operations team at ESAC is making sure we get the most out of every instrument.
Meanwhile, the Flight Control team at the European Space Operations Centre (ESOC) in Darmstadt, Germany, makes sure Juice is and stays on the right path. This episode shows what happened ‘behind the scenes’ before and during the lunar-Earth flyby, and stars Ignacio Tanco, Angela Dietz and members of the Juice Flight Control team as they do what they do best.
Finally, we highlight the ESA tracking station network (Estrack), another crucial component for Juice. Maintenance and Operations Engineer Belén Goméz gives a tour of the facility at Cebreros.
Following the very successful lunar-Earth flyby, Juice is now on its way to planet Venus for its next flyby. On 31 August 2025, this flyby will give Juice its second gravity boost. Tune back in next year for episode two of this series!
This series follows on from ‘The making of Juice’ series, which covered the planning, testing and launch of this once-in-a-generation mission.

![Comet C/2023 A3 brightens SOHO’s week (standard processing)
From 7 until 13 October 2024, ESA/NASA’s SOHO ( https://www.esa.int/Science_Exploration/Space_Science/SOHO ) spacecraft recorded Comet C/2023 A3 (Tsuchinshan–ATLAS), the second brightest comet it has ever seen. Meanwhile, large amounts of material were being spewed out by the Sun (covered in the centre), and planet Mercury is visible to the left.
The comet’s nucleus is clearly visible, surrounded by a dusty coma and trailing an impressively long tail. SOHO sees the large dust tail edge-on, curving in on itself as it is pushed outward by solar wind.
At the end of the video you can also see a rare phenomenon known as an ‘anti-tail’: a long, thin line that points towards the Sun. This tail is an optical illusion coming from SOHO getting an edge-on view of the larger cometary dust particles that accumulate in the comet’s orbital plane.
Comet C/2023 A3 was seen for the first time early last year. It most likely came from the distant Oort cloud ( https://www.esa.int/ESA_Multimedia/Images/2023/11/Where_do_comets_come_from ], and the last time this comet flew through the inner Solar System (if ever) was at least 80 000 years ago.
The comet reached an estimated peak brightness just beyond –4 magnitude. (The more negative the visual magnitude value, the brighter the object.) Of the more than 5000 comets ( https://www.esa.int/ESA_Multimedia/Images/2024/03/SOHO_reaches_5000_comets ) SOHO has seen flying past the Sun, only Comet C/2006 P1 (McNaught) ( https://sci.esa.int/web/soho/-/40529-brightest-comet-ever-observed-by-soho ) was brighter, with a visual magnitude of –5.5.
SOHO’s location between the Sun and Earth gave it a front-row seat, but the same comet has been visible from Earth every evening since 12 October 2024. Throughout October, as the comet moves farther away from the Sun, it will gradually grow fainter and rise higher up in the western sky.
The week that SOHO watched Comet Tsuchinshan–ATLAS was also a wild one in terms of space weather. The Sun unleashed no less than 4 X-class flares (the highest intensity type of flare), 28 medium-intensity M-class flares, and 31 coronal mass ejections – the latter being visible as white clouds of material in the video. All this activity led to two geomagnetic storms on Earth, resulting in beautiful auroras lighting up the night sky.
SOHO, short for Solar and Heliospheric Observatory, is a joint ESA-NASA mission to study the Sun. For almost 29 years now, it has been watching the Sun itself as well as the much fainter light coming from the Sun’s outer atmosphere, called the solar corona. The data shown in this video were taken by the LASCO C2 (red) and C3 (blue) coronagraph instruments.
The comet is so bright that it partially saturated SOHO’s sensor.

![The Sun: Super Active 2024 [Hinode/XRT]
As we approach solar maximum, the Sun is reaching new levels of activity for Solar Cycle 25. The Sunspot number has consistently exceeded predictions of the cycle with 2024 especially being way above what was predicted. That means we have been consistently seeing large numbers of active regions across the disk throughout the entire year. While this doesnt always mean large flares all the time, we have had periods (such as early May) where the Sun has produced some major flares. The last few months of 2024 are shaping up to continue this trend and we hope to continue to capture exciting solar data with XRT.
Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and the NSC (Norway). The XRT instrument team is comprised of SAO, NASA, JAXA, and NAOJ.
