My name is Joe Morrison, and I’m ready to be roasted on here again. Please feel free to ask me anything or challenge any of what I’ve written!

Hi Joe, thanks for the article. I am thinking of getting into satellite data science (from a data science/ software eng background). If you can recommend any datasets that are open to the public that can be fun to play around with or any other advice I'd be happy to hear it.

Not OP, but try https://datasetsearch.research.google.com/search?src=0&query...

There's a paperswithcode dataset that looks good, at a glance.

Thanks for this,

I am wondering whether to study a MSc in the field or whether just self-led work will suffice for progress,

I guess I will play with some of these datasets and see what I learn on the way.

First thank you for the article. Looking forward to Part II. Two questions: How do see the chances for other competitors to be able to catch up with SpaceX/Starlink? And are there some other challenges than congestested space and congestested frequency spectrum, when there will be several competitors in space?

> How do see the chances for other competitors to be able to catch up with SpaceX/Starlink? I like to remind people that it’s actually SpaceX who is still catching up to legacy providers of space-based connectivity. As I mention in the footnotes, my wife’s grandfather was working on commercial comms satellites in the 60s! Starlink will probably become the biggest provider of space-based internet connnectivity soon, b…

> their principle competitor among the new disruptive LEO constellations is Amazon

The main criteria should be: who has hardware in space ? So the answer is, despite all their problems, OneWeb.

Sounds like near-realtime Google Earth is still way, way off.

If you don't mind ~3m resolution you could pay Planet labs for a roughly once a day (weather dependent) Google Earth.

However, large parts of google earth uses aerial (i.e. non satellite) imagery.

So yeah, way of.

Also, if you do a quick back of the napkin math, it's a lotta data.

> SpaceX’s near-infinite fundraising capacity I have to wonder how sustainable this is. From the perspective of an investor, I would not be excited by Tesla being down 70% off peak and Twitter becoming the most notable corporate clusterfuck of the year. Investing in SpaceX these days seems like a bet that the CEO will be so distracted by his other problems that he won't have time to mess with the people actually runn…

Do you have ANY substantiation for Twitter being a coorporate failure or are you just parotting the biggest Twitter competitors (newspapers)?

What I actually said is "most notable corporate clusterfuck of the year".

We don't know how it's actually going. Musk is a notorious BSer, and as a privately held company, they don't have to release actual numbers.

But Musk took a company that was doing just fine, made a weed-joke-priced offer, changed his mind, tried to BS and wriggle his way out of the deal, and grudgingly went through it when it became obvious a chancery court judge was likely to force him to buy it anyhow. With that alone it was probably the most notable corporate clusterfuck of the year.

And that's before the actual takeover, where he loaded it up with so much debt that -- and this is according to him -- it could very well be bankrupt in short order. He then flailed around with his amateur-league management dramatics for months in ways that if you somehow missed, you can Google. All while ignoring a much more valuable company that's the source of his wealth as its stock price plummeted by 70%.

If you think there's a more notable corporate clusterfuck in 2022, please do name it.

If you work in the space, he is one of the most well respected people.

OK makes sense, this Payload Space blog is 1.5 years old. So Joe would be pretty experienced by those standards. Payload is also super SDA focused.. seems like an echo-chamber for the DoD.

Interesting, would you prefer we cover more commercial space?
