@ponderable saidDidn't hear about that one. What was the reasoning behind that move? I hear of technologies that involve capture, like a big bag or some such but what did they do?
Seems like Modi thinks like that. For me it is not. It is a technological one. But hitting something in Orbit to further litter space is not someting to celebrate.

In short India shot down a "life" satellite to Show that they can defend against attacks from space.
I would have much rather read that they caught a satellite and brought it down to earth.

@ponderable saidYes, especially if it was say a Russian spy sat and we could glean some info on its technology. Did they say how they killed it? Missile shot?

It's also reported here [1]. According to the article they shot down one of their own low Earth orbit satellites using a missile. The Indians claim that the resultant debris will clear in about 45 days, experts from other nations cast doubt on this claim. Although the article does not discuss this, I suspect that the purpose is to create an anti-ballistic missile defence. I don't think that there is a tremendous advantage in shooting down satellites.

@deepthought saidIt seems to me a collision with a missile and a sat would make a debris field that would send maybe half the debris into higher orbits and maybe half into lower crash orbits.

@sonhouse saidThe same reason China, Russia and the USA did it. To demonstrate that they can take out recon and GPS satellites.

EDIT - Missile from any number of platforms air ground or sea.

@deepthought saidYou don't? Killing comm. and spy sats, GPS, missile guidance systems and on and on. Sure slow down a war.

@kquinn909 saidThe game goes on in stealth sats and such. If they can't paint it with radar or see it in IR or some such, they can't be shot down.

@kquinn909 saidSpy satellite's are relatively easy to deal with. One simply needs to know when they are going over as far as tactical maneuvers are concerned and at the strategic level knowledge of what the adversaries analysts conclusions will be gives one a potential means of feeding false data. GPS and, I assume, communications and missile guidance are not in low earth orbit.

@deepthought saidStill, if there is a stealth sat was there say an hour later, they would reveal stuff the ones on the ground didn't want you to see. My guess is there are such out there already. You know, the Hubble isn't the only 2 meter scope on a sat, there are something like a dozen, only not pointing UP😉

@sonhouse saidSure, but these things are how nuclear non-proliferation and arms limitation treaties such as START are enforced.
