John Freeman is a PhD physicist who worked in industry for ten years, building and testing everything from e-cigarettes to industrial cutting lasers. He then tried teaching, and is still recovering. He writes guides to space and technology for authors, game designers, DM's and other worldbuilders, which can be found here: https://www.drivethrurpg.com/browse/pub/18101/John-Freeman

Hi everyone, as I'm closing in on the finish of the 4th booklet in this series, I thought I'd post a quick reminder about them:

Thierry Legault's Stunning Views of the Space Station (with spacewalking astronauts) Crossing in Front of Sunspots

He’s done it again, outdoing even his own incredible work. Over the years, we’ve written many articles to share the beautiful and mind-bending astrophotography of Thierry Legault. Each year he seems to come up with ideas to try to surpass even his own craziest attempts of astrophotography feats – such as capturing spy satellites in … Continue reading "Thierry Legault’s Stunning Views of the Space Station (with spacewalking astronauts) Crossing in Front of Sunspots"

I don't think that people should feel free to let garbage burn up in our atmosphere personally. I'd like to have all the space trash hauled out someplace closer to the moon where maybe it might get recycled someday.

@Scifiguy All interesting points, but I think there needs to be a discussion about when debris can be declared ‘free for salvage’. No business will try to clean up debris until international law provides a mechanism to declare the original launcher’s rights null. If a dead Soviet second stage is still zooming through increasingly full orbital altitudes, why can’t we allow someone to go out and clean it up? Maybe orbits should be considered like radio frequencies.

Space Law May Soon Focus on Space Debris Cleanup, Not Just Mitigation

A test mission that involves cleaning up a piece of space debris with a metal claw may preview how regulations could change in the future.

Another bit of anthropomorphizing is in this quote -- the verb 'realize' requires that the realizer be the kind of entity that can apprehend the truth of a proposition.

To be very clear, I think that autonomous weapons are a Bad Thing. But I also think that reporting about them should clearly describe them as tools rather than thinking/feeling entities. Tools we should not build and should not deploy.
