FYI - during this Venus flyby, Juice is using its steerable medium-gain antenna for communication with earth. The larger high-gain antenna will remain pointed towards the Sun to act as a heat shield.

This also implies that the imaging systems of Juice will not take any pictures during this flyby.

Note that the 32-bit counter ticking every 10 ms rolls over in 2^32/100/3600/24 = 497.1 days = ~16 months.

Juice was launched on 14 Apr 2023. The counter was probably reset in Jan 2023; this must be the 2nd rollover.

The #ESA Jupiter Icy Moons Explorer (Juice) is on its way to orbit and study 3 icy moons of Jupiter: Ganymede, Callisto, and Europa. ETA: Jul 2031.

The ESA Juice (Jupiter Icy Moons Explorer) spacecraft gravity-assist flyby of Venus was successfully executed at 05:28 UTC earlier this morning. No pics are expected.

Juice’s next planetary flybys will be at Earth in Sept 2026 and Jan 2029.

Congratulations to the team.
👏

Flyby success! ESA's Juice spacecraft passed Venus at 07:28 CEST on 31 August.

This photo shows our deep-space antenna in Spain in communication with Juice during the flyby.

Juice’s current location, Venus, and its destination, Jupiter, are both visible in the sky ❤️

Congratulations to the Juice operations team at ESA mission control in Germany for the smooth gravity assist that helped Juice pick up the speed required to get to Jupiter. 👏

Juice’s next planetary flyby will be at Earth in September 2026.

On, on, onwards, up the gravity well!
