So earlier today I talked about what VMC @esamarswebcam is and how it came to be 📷. Now I’d like to talk about my job at @esa, and the work I do for #VMC. This is an image of me, one of my supervisors, and @jorgeherber at ESAC, as we attempt to spell out 'VMC'! 😂🔴
As I mentioned yesterday, I work as a Young Graduate Trainee at @esa for @esamarswebcam. My role involves planning science observations for this instrument 🔎, processing the data 🖥️, and archiving it 📚. So I get to be involved in the whole chain for VMC data, which is great!
For planning science observations, we use a software called MAPPS (Mission Analysis and Payload Planning System). On the left is a planned image in MAPPS 3D, & on the right is the image taken in January this year, showing a cloud over Olympus Mons volcano ☁️🌋
VMC usually observes from near apocentre (the part of MEX's orbit which is furthest away from Mars), as shown in e.g 1, but sometimes also observes closer to pericentre (the part closest, 2). Limb observations (3) are also squeezed in around observations by other instruments! 🛰️
I was really lucky that soon after I arrived at ESA, my supervisor was happy to give me considerable responsibility for VMC, & so I get to plan the observations! (usually done ~2 months in advance). Closer to execution, my colleague @jorgeherber optimizes the exposure times 📸
So what about after the observations are taken? A major part of my time at ESA so far has been establishing a data processing pipeline for VMC and working on calibration for the instrument, with the invaluable help of @jorgeherber & @marwood82, + the rest of my VMC colleagues! 🖥️
The goal is to put VMC on the Planetary Science Archive (PSA - archives.esac.esa.int/psa/) which is where all @esa's planetary science missions archive their data. We recently got back the 'science archiving review', which is necessary bc VMC is a 'new' instrument for the PSA 📷
We're now implementing the last few changes, and expect to have VMC on the PSA in the ~next couple of months (which I'm super excited for!!). In the meantime, you can find VMC images uploaded directly to Flickr (sometimes only a day after being taken!) 🔴 flickr.com/photos/esa_mar…
Finally, when we have this data processed, what are we doing with it? Well, the latest study from the VMC team led by @jorgeherber and recently submitted for publication, is about an extremely elongated cloud over Arsia Mons volcano on Mars! ☁️ I'm very excited about this 😀
If you want to know more about VMC, the presentation I recently gave at #shareEGU on behalf of the VMC team is uploaded publicly on ResearchGate here: researchgate.net/publication/34…
Later this week I hope to show you some of my favourite images taken with #VMC#MarsExpress@esamarswebcam 📷. So, tldr; I get to be involved with VMC observation planning, data processing + archiving, plus science studies, and we hope to have VMC data on the PSA by summer! 😀🔴

PEOPLE OF SPACE! I’m super excited to be hosting this week! We’ll be covering a bunch of topics that are near and dear to me including #space (obviously), astronomy, supernovae, radio astronomy, science communication, and MORE
🧵 #science#scicomm#spacetwitter#intro#Thread
But who is this random dude yelling at us about space?
Well the short version is that I’m a physicist who finished high school with every intention of becoming a lawyer - pictured is 19yo me not caring about science #accidentalscientist#accidentalphysicist#throwback#SPACE
The mission patch was based on a design from well known Italian fashion designer, Emilio Pucci. The design has three stylized birds flying over the Hadley-Appenine landing site with the crew names on the lower part of the outer border.
In an early version of an Easter egg, the crew snuck a Roman numeral XV into the crater shadows. According to a story I heard from one of Al Worden's @ExploreSpaceKSC presentations, NASA discouraged Roman numerals on the Apollo patches, thus the hidden nature.
Before his passing last year, @WordenAlfred was a regular astronaut host at @ExploreSpaceKSC giving presentations guiding tours and being an affable ambassador of the Apollo program to a new audience.
On board were (left to right) Lunar Module Pilot Jim Irwin, Commander Dave Scott, and Command Module Pilot Al Worden
The landing site was Hadley-Appenine, on the edge of Mare Imbrium. It was bordered by Hadley Rille, a valley-like geological structure and the Montes Apenninus, or Appenine Mountains. The Palus Putredinus was a lava field that filled the area.
Today I’ll be working on some research for the big Mars exhibition! As I said yesterday, I’m working on researching how people have been imaging the Red Planet throughout history.
Today we have orbiters circling Mars and rovers that take pictures of the surface. But the history of imaging Mars stretches back centuries, from depicting Mars in art to the canals people thought they saw on the planet.
What are some of your favourite images of Mars and why?
Going to talk about designing a temporary display today!
In Science Museum lingo, there are 2 kinds of displays:
🚀Exhibitions (temporary displays) - these can last up to a year
🚀Galleries (permanent displays)
Even a temporary display might take several years to prepare for, with overviews and detailed proposals.
Exotic solvents & life's building blocks are among the more speculative #astrobiology topics, but still important to study scientifically! Our own system contains places potentially able to host life unlike on Earth. Not just Titan!
All Earth life is carbon-based and needs water to survive. 💦
'Mildly' exotic life might share these traits, but use e.g. other information molecule (or differently coded DNA, even with different/more 'letters') or opposite chirality (left/right-handedness) of some compounds.
There are countless possibilities of different information molecules and their coding. Is Earth DNA and RNA a ', frozen accident', or does it have a phys/chem reason? And is all life chiral? In the same way, or is that another frozen accident? What about the amino acids we use?
