Hello everyone 👋 I'm Mars (@TheMartianLife) and I am your host for this week.

A quick intro: I am a PhD candidate at @UTAS_/@CSIRO working on using Machine Learning to improve tracking precision and reliability for satellites and space debris.
Before this, I had never worked in space before (though I was a BIG enthusiast); I actually came from computer science, where I have worked on ML for a range of other domains.

Needless to say, I am very excited to be able to combine the two. And for such an important issue 📡~🛰
And I'm from Tasmania. Over here at UTC+10 and down here at 42°S it's just gone 6am Sunday and it is still pitch black as we're coming into our short Winter days.

...so forgive me if I start a bit slow this morning 😆 Screenshot: Google Maps, with Tasmania searched. The result
And I have been reliably informed that I am in fact the first Tasmanian to take the helm here at PoS and so you can expect lots of content celebrating this beautiful island I call home, which has a long and ~often overlooked~ history of all walks of astronomy.

🧵 I'm sure you've heard of the "space debris crisis". We knew about it in the late '70s + by the early '00s we had a robust set of laws that established the 25yr rule, required operators to design craft to withstand minor collision + to minimise the odds of in-orbit explosion...
It's fascinating that even in the time I have read about it we have learned so much about the problem, though often we only find it turns out more difficult than previously thought 😕

Pre-Kessler it was thought "natural removal" (i.e. orbit decay) would take care of most...
By 2005, when I first heard about the problem from an @esa article, we were speaking mostly about RB explosions from leftover fuel in orbit, and from objects breakups that occurred over time due to expected degradation of materials.

Grote Reber (the inventor of the radio telescope) moved to TAS in the 1950s + spent the rest of his life here, after recognising conditions ideal for his work.

.@UTAS_ operates a buncha telescopes in picturesque locations across the state, both radio + optical, but there is also a big independent/hobbyist community here.
Astrophotography 📸✨ is a hit here due to our lack of light pollution, and we also get the 🌌 Aurora Chasers 🌌 A large radio telescope sits on a green hill surrounded by gA map with overlay shows light pollution levels around Tasma

So a final thread from me as your host today: some top tips on how to write for a popular audience about complicated subjects #space #science #writing #storytelling
The essence of any good communication is simplicity. It’s the same in print, television, radio, online, or attaching notes to carrier pigeon’s legs.
In the sixties, a Granada current affairs show set the template for using a visual medium more effective: it was pioneered by a remarkable fellow called Tim Hewat, a flavour of whose personality is here: theguardian.com/news/2004/dec/…

So for my final half day, I wanted to share some "top tips" on writing for a popular audience - especially about space, and I already collected some thoughts here, but will now take the opportunity to expand on them where I can twitter.com/i/events/12229…
Before I begin, I will obviously refer to Dick Feynman a great deal, because as I explained, quite by accident I came into his orbit and Al Hibbs, both of whom knew how to explain things
In 1981, Chris Sykes literally pointed a camera at Feynman and let him talk. Fifty minutes of utterly compelling television. And here is the story behind that.

So my final thread on this last full day of tweeting - and my God what a day for anyone who is interested in .... checks notes.... Mars. What I wanted to do is make a few points about journalism .... and in particular, people who write about space #Mars #JournalismIsNotACrime
To set some context, then, what exactly is a “space journalist”? It is an interesting question and one which is fairly easy to answer. As a journalist, your function is to report what happened and also why.
In that last photo, the bearded fellow at far right was one of the most extraordinary space reporters I ever met - and I was just out of shot when that picture was taken btw. Jonathan Eberhardt was an award-winning reporter -- washingtonpost.com/archive/local/…

So as I suspected I would be exhausted today, being an industrious sort of fellow, I had prepared some tweets ahead of time if #Perseverance hadn't worked........ but with a little tweaking, still relevant #countdowntomars

@xipteras
As everyone who follows space knows, there is a narrow line between success and failure - and there but for the grace of God.......telegraph.co.uk/news/2021/02/1…
As many of you know, the British tend to celebrate failures and heroic ones at that..... newstatesman.com/culture/books/…
