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?
Time for a detour to talk about imaging and imagining Mars!
First, a disclaimer: much of the historiography (ways that historians write about history) of science - including the history of imaging - is WEIRD.
There are a couple of different ways that people generally do historiography of science: 1) an “old-fashioned” view aimed at getting to the “right answer” of how we do science today 2) a view that looks at what would have been the research at the time
1) is not great history because it tries to reconstruct the past through the lens of the present. 2) is better and more interesting history but is less accessible
I want to move beyond the “old-fashioned” historiography of saying “the ancients did this, then now in the modern day we do this”.
Still, today we have a crucial piece of tech that the ancients didn’t: the telescope.

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?
Though discovered already in the late 18th century by William Herschel, we had long known extremely little about it. 🔭
That changed with the Voyager flybys! 🛰️
This image was taken by Voyager 2 on August 25, 1981, from about 110,000 km away. It shows cratering, but also bright ice, grooves, some crater-poor areas. That suggested parts of the surface were very young - the tiny moon was active!
If you were to search for extra-terrestrial life in the Solar System and had a budget for let's say a medium-class/New Frontiers mission, where would you go? 🛰️
Not doing a poll; too many possible good answers!
For me, though, 🪐 moon Enceladus is (narrowly) the top choice.
There are other great options, of course!
Venus.
Mars.
Europa.
Titan.
Less likely other subsurface ocean-bearing moons or dwarf planets; we still know so little about them all!
Venus is great from the overall planetary science perspective. It's so frustrating that we still have little clue whether it had once possessed oceans, for how long, and when and how fast it changed into the current greenhouse hell!
While the deadline for this year's opportunity to apply for #ESA student sponsorship for the #IAC passed a week ago, I'd like to share my overwhelmingly positive experience of the program from 2016, so that you can decide to apply next year if possible! ⬇️
I was finishing my MSc. in early 2016 and I was active in space outreach - organizing seminars, writing popular science articles for mags such as @Vesmir1871 (CZ) or @clarkesworld (EN) and trying out space workshops for kids, and I had ideas to put in an abstract for #IAC2016.
I learned about the ESA sponsorship opportunity covering the conference fee, accommodation & travel cost and was excited! I submitted my abstract to the outreach session of IAC and applied for the program, outlining my reasons for wishing to attend + shooting a short video.
For as long as I remember, I've loved science and also science fiction. 🚀 Science came first for me, but for many, it's been the other way around.
SF is great for inspiring future scientists and igniting interest in science. Luckily, #scicomm & #outreach has begun to notice! ⬇️
I'm currently leading the 'Science Fiction as An Astrobiology Outreach & Education Tool' at @EAIastrobiology. We used reprint SF stories accompanied by original science essays in 'Strangest of All', released last spring to aid outreach amidst lockdowns.
The positive response prompted us to edit a bigger, more ambitious print book of original astrobiological SF and essays. Titled Life Beyond Us, it's just funded on kickstarter and will be published next fall around the launch of @esa's Rosalind Franklin!
