🤔In space, no one can hear you... make an orbit-bending flyby of Mercury. So BepiColombo recorded its vibrations and turned them into sounds

We had an exciting time at ESA ESOC yesterday watching these beautiful images come in. These already amazing views are from engineering monitoring cameras; the science cameras will give us far better images after we arrive in orbit in late 2026. #BepiColombo
Our top three images from the sixth Mercury flyby are here! 🌗 See what they reveal about the mysterious planet here 👉 https://t.co/osfrjGs2t5 and in 🧵👇

Exciting days ahead - the final encounter with Mercury until #bepicolombo enters orbit around the planet in late 2026.
🛰️🌑We're gearing up for BepiColombo's sixth Mercury flyby, coming up this Wednesday! ℹ️Closest approach is 295 km at 06:59 CET We'll investigate Mercury's cold night side, north pole craters, and the vast northern plains 👇 https://t.co/ec7qs13G4E

Last week, @BepiColombo became the first spacecraft to image planet Mercury in mid-infrared light 🔥 Using @MERTISonBepi, the mission will uncover what Mercury's surface is made of 👇 https://t.co/XdbDSaZzXV

On 1 December 2024, BepiColombo flew past Mercury for the fifth time. During this flyby, BepiColombo became the first spacecraft ever to observe Mercury in mid-infrared light. The new images reveal...

Mercury in motion... One of the #BepiColombo selfie-cameras captured Mercury today as the spacecraft rushed by the planet at almost 3 km per second. 🛰️💨 This time-lapse of unprocessed images was captured during 10:26-11:18 UTC today (11:26-12:18 CET), between 53700 and 48000 km

A successful encounter! #BepiColombo passed Mercury today, gathering valuable science data. 🛰️🌖 As expected, as we were further from the planet than during previous encounters, the planet was quite small in the selfie-cam pictures. Here's an image taken at 10:46 UTC (11:46

Right now, #BepiColombo is at its closest point to Mercury during its fifth encounter with the planet. The spacecraft is 37 360 km from the surface. Data gathered by its instruments will be sent back to Earth during today and tomorrow. 📡⚡️🛰️

Coming up this Sunday! #BepiColombo #Space
This Sunday, @BepiColombo will fly past Mercury for the fifth time. Here's an overview of what you can expect 👇 https://t.co/Q5c5mdFpkB

#BepiColombo will fly less than 40 000 km above Mercury's surface this Sunday, marking its fifth flyby of the planet. 🆕Its MERTIS instrument will observe the planet in mid-infrared light, making BepiColombo the first spacecraft ever to do so 😎

That straight line across the Sun's disk (arrowed) in @MissionSoho LASCO C2 images is part of #CometC2023A3 's dust tail, which is lying in a sheet in the comet's orbital plane. Earth will cross it at a different time to SOHO, as Sun-SOHO-Earth is not a perfectly straight line.

These teeny-tiny grains near Earth are literally being pushed out of the solar system by the pressure of sunlight! All of the dust lying between us and the Sun will form a line running across the Sun's disk in a few hours, as we cross the "fan" of dust in the tail. #CometC2023A3

Earth, together with @MissionSoho & other spacecraft at Lagrange Points L1 & L2, will cross #Comet Tschuchinsan-ATLAS's dust tail today. The tiny particles reaching Earth left the comet around 2 weeks ago, & are affected >3 times more by sunlight than by Sun's gravitational pull.
Pretty cool to see the dust trail of Comet Tshuchinsan-ATLAS entering the upper-right corner of @MissionSoho LASCO C2! The reason it's still so visible is because of that "forward scattering" effect we've been taking about, i.e. the dust is being "backlit" by sunlight

Sit back, relax, and enjoy this beautiful timelapse of last week's Mercury flyby, set to some special music inspired by a crater that appears in some images 😉

For non-Welsh speakers, the Google translation of the above tweet is largely gibberish! It should start with "From Anglesey to Mercury..."!

Its closest pass yet and its first-ever views of Mercury's south pole – last night was quite a night for #BepiColombo! Enjoy this taste of our fourth Mercury flyby. Details & images 👇 https://t.co/iKzONy9CGZ

The ESA/JAXA BepiColombo mission has successfully completed its fourth of six gravity assist flybys at Mercury, capturing images of two special impact craters as it uses the little planet’s gravity...

Our #BepiColombo @esaoperations team confirm all went well with our Mercury flyby last night. Now we wait and see what images & data our instrument teams collected! Stay tuned for a selfie-cam update later today. Here's a sneak preview 🤫
