I had a little vision of the future. Lathe touching time.
The distinction of the “second missile age” over the “first missile age” is the use of GPS systems for accurate terminal guidance to the point that conventionally-armed missiles have become a useful tool. All major powers have deployed/are deploying regional high-orbit GPS navigation systems. Some of those regional systems (BeiDou-2) are now global (BeiDou-3). Low-orbit data constellations like Starlink could theoretically also be doubled up as jamming platforms to drown out the higher-orbit navigation networks over certain areas, since all GPS constellations operate on the same narrow band of frequencies. Both of these constellation types (high-orbit GPS / low-orbit data) have dual purpose economic and military use, which assures their continued existence because they are a national boon rather than just a military expenditure.
Most space powers have anti-satellite missiles which can be used to hit low-orbit spy satellites, but in order to take out large numbers of low orbit satellites in string constellations like Starlink, you’ll need something with a better cost ratio; a mobile(ship/air) laser system which you can sit underneath the orbital string and fry them beyond use one by one.




It’s not intentional - the author has stated that he tries to avoid his stories being “woke”. The stories he writes often include themes about international cooperation to save something, and as such they tend to swerve around the liberal condemnation of “authoritarianism”. For western books, the idea of international cooperation means China/Russia featuring prominently coming to the rescue, but if Andy Weir was Chinese, the same trope would be, for example, a JAXA spacecraft helping out a beleaguered Taikonaut.
For a moment, consider how incredible it is that a movie clearing the low bar of “considering foreigners as human” is enough for us to ask if a movie is friendly to the idea of socialism.
