Space debris

jeudi 18 novembre 2021 à 00:05

Russia used an antisatellite weapon against an old Russian satellite. Such tests create space debris, which we don't have a way to clean up. That is a grave, persistent, accumulating problem.

The ultimate danger of space debris is that a chain reaction of collisions could make so much debris that it would destroy all satellites, and we could never put up satellites (or spacecraft) again. An accelerated version of this was shown in the movie Gravity. I think that was unrealistically fast, but no one would dare build and launch a spaceship if its collisional half life were as little as ten years. Everything human would be excluded from space, except for the hypersonic nuclear missiles that China and the US are testing. (They don't need to stay in space for very long.)

The US tested an ASAT missile and was rebuked for wantonly creating space debris.

Every so often I see a proposed system for cleaning up space debris, I don't think any of them would scale to the amount of debris present in Earth orbit in recent years.

Digital panopticon

Employers are increasingly turning their workers' computers and homes into a digital panopticon.

This article describes a museum's projection of the British home of 2050, recognizes it as dystopian, and displays displeasure only rather mildly.

Some of these automated features could respect your freedom if they are implemented in libre software and run on your own libre platforms. If we want that, we had better start rejecting the user-subjugating platforms now.

One suggestion: when you enter a house, ask whether there are listening devices such as Alexa, or video insecurity cameras, and as to unplug them. Even if you don't insist, at least people will learn that what they are doing is problematical and some people don't like it.

To mask the cruelty of Fortress Europe.

*Lukashenko is a handy villain to mask the cruelty of Fortress Europe.*

I disagree with one subtle point: the EU's actions and Lukashenko's actions are not parallel. Lukashenko actively lures migrants, so he can use them as weapons; the EU simply wants to keep them out.

*On trial for saving lives: the young refugee activist facing a Greek court.*

Americans who provided water and other humanitarian assistance to migrants in the desert a few years ago were likewise charged with aiding their entry.
