Brilliant, #ESAJuice got itself an XKCD! #planetsci
I’ve got a soft spot for Europa Clipper, but I have to admit that JuIcE is a catchier name.

The NASA/ESA/CSA James Webb Space Telescope has observed Jupiter’s aurora.
The observations help astronomers better understand how Jupiter’s upper atmosphere is heated & cooled, and may prove useful to our #ESAJuice mission, en route to the gas giant.

Reminder that ESA's Jupiter Icy Moons Explorer (Juice) flies past Venus this weekend. The spacecraft was designed to feel at home in the cold, dark environment of the Jupiter system, and it is too hot at Venus to turn the cameras on. Pics or it didn’t happen? You’ll have to trust us on this one.

Happening today: #ESAJuice inbound! Our Jupiter-bound spacecraft will fly high over the Indian Ocean in a few hours, picking up speed, with closest approach at 1145UT = 1245BST = 1345CEST = 0745EDT
Everything you needed to know about #ESAJuice returning to Earth for a flyby next week! Our spacecraft is now 41% of the way through its long journey to Jupiter. #planetsci
Juice is returning to Earth, again 🛰️
On 28 September the spacecraft will fly by Earth, coming within 8640 km of our planet.

If it's the 14th of the month, it's time for the #ESAJuice bar!
The animation below shows Juice's altitude transition from 500 km to 200 km above Ganymede, an update announced earlier this year.
The new phase of 30 days at 200 km will enable a more detailed investigation of Jupiter's moon.

To properly reach the Jupiter system in July 2031, #ESAJuice relies on ephemerides - predicted positions of celestial objects at specific times.
Mid October, you have a chance to help improve those ephemerides.

Any Sydney-based astronomers here? A team at Andalucia is coordinating an occultation campaign for one of Jupiter's small (2-5km) irregular moons, #Kallichore (a candidate for an #ESAJuice flyby) that'll be passing in front of a star at ~12:20UT on March 18th.

Juice is 40% of the way into its journey and getting ready to return home for an Earth flyby next month.
Teams are busy preparing for this milestone, which will see all 10 of Juice's instruments switched on, taking photos and collecting science data. Stay tuned!

After a world-first Earth-Moon double gravity assist in August 2024, our @esa.int #ESAJuice mission passed its hottest point enroute to Jupiter. On 1 January 2025 🎉, #ESAJuice was just 0.64 AU from the Sun. A flawless deep space manoeuvre was executed at midnight to adjust our trajectory to Venus!
