Hi fellow space-people! 🚀 Tuesdays are busy days for #MarsExpress (MEX), and so I'd like to take you through what I'm working on today as a Young Graduate Trainee for MEX. Later, I'll do a thread on the YGT scheme at ESA & other @esa opportunities! 🛰️ (Image credit: ESA) Image
As I discussed yesterday, as part of my work I get to plan observations for VMC @esamarswebcam, & that's what I'm doing today! My setup currently looks like this (the different colours on the 💻 represent different instruments, events etc, & the colours on Mars = elevation) 🔴 Image
(When I first started, I remember my supervisor zipping through these screens with all the colours and me thinking, I'm never going to be able to understand all this 🤪 but after a few planning cycles, it all starts to make sense!) 🖥️
Today I'm adding 'additional limbs'. We plan MEX observations in 'Medium Term Plans' which start ~3 months before execution. VMC apocentre observations get added then, & limb observations are squeezed in at the end once the other instruments are fixed ⌛️
At 2pm, we have our weekly telecon with the MOC (Mission Operations Centre) at ESOC 🇩🇪 (thats @esa's European Space Operations Centre, where all the missions are actually 'flown' from 🛰️). It's v cool our colleagues are now flying a spacecraft from home! esa.int/Enabling_Suppo…
Later this afternoon at 4.30 we normally have our telecon with the instrument teams & project scientist to discuss the ongoing planning of science observations. At planning cycle Kick-Off meetings, we also get reports from the teams on how their observations are being used 🔬📶
When I finish the observation planning later today, I'll go back to processing data for @esamarswebcam 📷 and making the final changes to the products (including documentation) that we're going to archive on the Planetary Science Archive:
So tldr; Tuesdays are busy days for #MarsExpress bc we have our weekly meetings with both the Mission Operations team & the instrument teams. Today, I'm working on adding some additional limb observations for #VMC @esamarswebcam and then I'll go back to data processing! 😀🔴📷🛰️

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

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 10 years ago before I had considered a career in science - I
For a slightly longer version you can check out this #thread I did on my @funfactscience account recently to reintroduce myself to #spacefam and any newcomers to my page

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.

🧬 Life as we don't know it 🧫

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!

#AstroThread
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. ImageImage
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? Image
