Earlier I discussed some of the highlights of the #MarsExpress mission as a whole. Now, I want to share something I promised earlier this week: some of my favourite images taken by VMC @esamarswebcam! https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🛰️" title="Satellite" aria-label="Emoji: Satellite"> Heres a & #39;double vortex& #39; in 2012 near the north polar cap (https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">: ESA)

(I talked earlier in the week about what VMC is: https://twitter.com/People_Of_Space/status/1262373593062637568?s=20).">https://twitter.com/People_Of... In this thread I& #39;ll use a combination of VMC images available on Flickr & VMC images processed by our internal pipeline (but only where they are already in the public domain). Now: pictures of Mars! https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle">https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">

Time for a close up! This is a photograph of Valles Marineris, taken by VMC in 2008 https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle">https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">. Processed using our internal ESAC pipeline. (https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">: ESA).

VMC managed to catch the caldera of Olympus Mons in October 2019! https://abs.twimg.com/emoji/v2/... draggable="false" alt="🌋" title="Volcano" aria-label="Emoji: Volcano">https://abs.twimg.com/emoji/v2/... draggable="false" alt="😀" title="Grinning face" aria-label="Emoji: Grinning face"> Processed using our internal ESAC pipeline.

Speaking of Olympus Mons, I love this image of a cloud over the volcano! https://abs.twimg.com/emoji/v2/... draggable="false" alt="🌋" title="Volcano" aria-label="Emoji: Volcano"> (actually, I already shared it when discussing how we plan observations: https://twitter.com/People_Of_Space/status/1262496339071549441?s=20">https://twitter.com/People_Of... https://abs.twimg.com/emoji/v2/... draggable="false" alt="😀" title="Grinning face" aria-label="Emoji: Grinning face">). Processed using our internal ESAC pipeline. (https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">: ESA).

This is an image of the northern polar cap of Mars, taken in January of this year. I love seeing these images of the beautiful patterns visible! https://abs.twimg.com/emoji/v2/... draggable="false" alt="❄️" title="Snowflake" aria-label="Emoji: Snowflake">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🏔️" title="Snow capped mountain" aria-label="Emoji: Snow capped mountain">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle"> Processed using our internal ESAC pipeline.

The wonderful thing about VMC @esamarswebcam is how accessible the images are & have been for many years. @landru79 has produced some fantastic videos of VMC observations, including these videos of flybys over the North polar cap https://abs.twimg.com/emoji/v2/... draggable="false" alt="❄️" title="Snowflake" aria-label="Emoji: Snowflake">https://abs.twimg.com/emoji/v2/... draggable="false" alt="📽️" title="Film projector" aria-label="Emoji: Film projector"> https://twitter.com/landru79/status/1219643223943065600?s=20">https://twitter.com/landru79/...

This is a great image from November 2019 to illustrate the fact that we can see & #39;twilight clouds& #39; with VMC @esamarswebcam (the subject of our next study as a VMC team led by @jorgeherber!) https://abs.twimg.com/emoji/v2/... draggable="false" alt="☁️" title="Cloud" aria-label="Emoji: Cloud">https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🛰️" title="Satellite" aria-label="Emoji: Satellite">

I love this image from 2017 showing a dust storm over the northern polar cap! https://abs.twimg.com/emoji/v2/... draggable="false" alt="❄️" title="Snowflake" aria-label="Emoji: Snowflake">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🌪️" title="Cloud with tornado" aria-label="Emoji: Cloud with tornado">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle"> Processed using our internal ESAC pipeline.

And finally, an extremely elongated cloud over Arsia Mons! https://abs.twimg.com/emoji/v2/... draggable="false" alt="☁️" title="Cloud" aria-label="Emoji: Cloud"> @jorgeherber discussed this more in this EGU presentation: #discussion">https://meetingorganizer.copernicus.org/EGU2020/EGU2020-433.html #discussion.">https://meetingorganizer.copernicus.org/EGU2020/E... So tldr; #MarsExpress VMC @esamarswebcam has taken lots of amazing images of Mars, & I& #39;ve shared some of my favourites here https://abs.twimg.com/emoji/v2/... draggable="false" alt="😀" title="Grinning face" aria-label="Emoji: Grinning face">https://abs.twimg.com/emoji/v2/... draggable="false" alt="📷" title="Camera" aria-label="Emoji: Camera">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle">
