You are trying to solve a problem. How do you decide what data to neglect? When to neglect? This one is on #scoping. And #modelling. Mostly.

This is a set of frames of the surface of Comet 67P taken by the Rosetta mission on 1 June 2016. The particles in the foreground are bits of dust and ice or cosmic rays effects. The "waterfall" of points moving in the background are stars.

Common illusions about #teaching: Anyone can teach Teaching is a job, not a profession Teaching is a calling, not work Teachers work short days and have summers off Teaching is easy Good teaching is all about fun Teachers just need to know their subject 🧵

This rather creepy photo is Artemis II’s heat shield underwater, as taken by the U.S. Navy. This is the first photo we have of the heat shield, and upon initial examination it doesn’t seem to have the char loss that Artemis I’s had.

The scare was such that, with the #OuterSpaceTreaty putting liability on the satellite’s owner, US decided to pass domestic law capping how much damage they were financially on the hook for. The contamination, of course, had no such cap. One has to love History.

#NASA is racing to put a nuclear reactor on the Moon. It's "safe" and "reliable". Well... in 1964 the US satellite SNAP‑9A failed, its plutonium power source burned up on re‑entry, spreading Pu‑238 worldwide which was, in later risk models, tied to thousands of extra cancers. 🧵

Joining the chorus of commentaries about Artemis II as countdown continues. I'm actually only mildly excited. I'm more concerned about what comes next in this geopolitical competition. And to be clear: my bet is on China having the lead, and that not being all bad open.substack.com/pub/spacecit...

My take on this: To become good, one needs not to be good first. Increasing criticism on the AI use only leads to a higher use of AI to avoid criticism. You see what I've done there? ;)

Good article. The way communication is being done also doesn't help building trust. Though NASA-led, Artemis is a collaboration, something barely mentioned in the media. If you have space agencies contributing that you consistently forget to mention, they will eventually start distancing themselves.

“Surely there’s a smarter way to do this” is easily in my top three daily thoughts. Hardman’s latest piece treats the course as a historical convenience rather than the pinnacle of #learning design, and shows how #AI quietly removes many of the old reasons we leaned on it so heavily Worth a read.

One odd side effect of working in space is realising how much of your job runs on law and politics you only half remember from a slide deck. This offcut is about the map Artemis II is sailing through, and who gets to draw it (or not). #Space #SpacePolicy #Artemis #SciCom

The #Artemis II Orion spacecraft is equipped with four solar arrays, built by engineers from Airbus Space in the Netherlands. Installed on the European Service Module, these arrays are essential for providing power for Orion and its crew as they travel around the Moon on this historic mission.
