Question: If all the current satellites were destroyed at once. What would that change tomorrow? Some things I can think of: -GPS/GNSS. -Weather measurements. -Sat TV / news. -Some comms.

I am just thinking that it wasn't that long ago that we didn't have any of that, and we still managed two world wars just fine.

Alternatives to these are: -Knowing where you are/someone else is. -terrestrial weather measurement. -Short wave radio.

Planets around red dwarfs are less likely to be habitable. Red dwarfs are far more temperamental than Sun-like stars, flaring often which irradiates nearby planets (which need to be very close in to be in the habitable zone).

The desire to detect near earth and potentially threatening objects has been a recurring theme in proposals for detection equipment, budgets and observation time for at least several decades. It might not be the headline reason, but it often makes the list. NASA has also built up an extensive library of such discussions over the years. I hope that makes you feel better.

i love they start nuclear propulsion in space specially things like the dual NTP/NEP design they were posting a few days back because the best that NTP alone can do is twice as better than chemical and we need better than that

this post is about nuclear propulsion the rest of your comment smacks of acolites of the church of the fissiontology pushing propaganda created by fossil fuel to slow the adoption of clean energy and doesn't belong to this discussion
