@BepiColombo And as today we're celebrating eight years since @BepiColombo left for Mercury, we've asked the team to describe the mission in three words.

Can you guess which word came up the most?

On 9 December, two little explorers, Bepi and Mio, will part ways as they approach their final destination after a journey that started 8️⃣ years ago today 🥹

Send them a #WelcomeToMercury message to cheer them up at this bitter sweet moment.

Next stop: Phobos & Deimos 🌑

MMX has successfully launched from Tanegashima, Japan. Its mission is to observe Mars’s mysterious moons, collect a sample from Phobos's surface and return it to Earth.

A prolific decade in Mars orbit.

@esa’s Trace Gas Orbiter slipped into orbit around Mars at 17:24 CEST on 19 October 2016.

Here are some impressive facts and figures about our largest Mars explorer 👇

. @ESA_Euclid discovers its first comet ☄️

That's quite impressive for a #DarkUniverse detective 🕵️ meant to take deep, steady images of distant galaxies, not fast-moving tiny objects.

On 9 December, @BepiColombo officially arrives at Mercury and you can join us 🙌

Enter our #WelcomeToMercury competition and you could win a trip to ESA in Darmstadt, Germany, where we will receive the signal from Bepi and Mio separating.

All details are here 👉 https://t.co/bSCWiUiJEz

[ESA Science @esascience]

Bepi and Mio are eagerily checking their inbox waiting to hear from you! 📭

Send them a #WelcomeToMercury message and you could win a trip to ESA in Darmstadt, Germany, this December to experience BepiColombo arrive at Mercury.

What can nine hours in Earth’s shadow teach #Juice about how to explore #Jupiter? A lot! 🌑

Teams got to:

🔋 Test the spacecraft’s batteries
🔬 Do science in the dark
📷 Exercise autonomous navigation

All while Earth helped steer Juice towards Jupiter.
