Unless some pieces were boosted higher by the explosion. But I guess they are confident this could never happen.

Orbits are periodic. If it is boosted up, it'll come back down. Orbital decay will still happen.

Eventually.

Because the assembly polls didn't show bjp leading by as much as expected.

So you think the entire exercise was carried out for BJP to pull ahead in elections? How much do you think Indian citizens care about this? Do you think it is enough to swing votes? Don't be too quick to find faults!

Not the entire exercise. But the publishing of the fact imo is to grt better traction for the election. Between such announcements and the modi biopic movie during the elections, i am betting that modi marketing momentum is not going to stop.

So... Don't announce scientific achievements by your national space agency during an election? Talk about skewed perspectives.

Wait, now I'm confused... is it a military national security issue or a scientific achievement? China managed to not have Xi Jinping announce when they did it.

Yah man. We need to celebrate space agencies/scientists even less.

Strangely, I'm not seeing a wide enough condemnation of this. Another country is building destructive weapons, bringing down LEOs; how is this a good thing? All the while the region suffers from chronic poverty, poor access to clean water and basic services. Sending a science mission to space is great and rightly lauded, this is wasteful and energies spent better elsewhere.

Advancing your countries technological capability and dealing with one of the largest populations living in poverty are two separate endeavors. Expecting a country to abandon growth in one sector to improve another is not really sensible. Both challenges are being tackled simultaneously. The US conducted Apollo and the Mars missions, spending billions while people in Skid Row or Detroit live in 3rd world level poverty.

This is a common argument (bordering on memetic and cached) and well, the budget for ISRO is about 170M USD, rounding up and considering steady increases lately. That 1:9 compared to recent outlay for just healthcare in the budget, after some basic googling. And strategically, India’s historically wanted increased self-sufficiency after the colonial era, and you need deterrence and military power to protect your own interests. So, it seems to just follow from basic needs and doesn’t seem to be out of whack. ISRO handles a ton of commercial launches too, and space industry is growing more and more — makes economic sense to continue to compete and iterate.

I've seen some criticism from certain individuals. However, I haven't read any condemnation from any Western government(as yet). I'm not sure but Western governments(or at least the US government) was probably taken into confidence either before the event or soon after the test. Considering that China already has this tech, it becomes paramount for India to have it. I think this is generally supported by the US(the government) as well.

Developing such such security apparatus doesn't mean we are ignoring poverty and other essential things. Both can be done simultaneously, just like the US did(explained by a sibling comment).

Such a huge step toward more peace in the world. What do you expect when world major democracy advocates are also the world major weapon sellers. I don't think there is any technological glory on destroying a satellite that deserves such a public announcement. Perhaps it is far less complicated than putting a satellite into space which is what India was already good at it.

>>I don't think there is any technological glory on destroying a satellite

We are talking about the capability to track and destroy a live satellite in space in under a span of 3 minutes with precision. There is a significant amount of technology involved here right from the types of propellants, precise navigation controls to steer rock in a specific direction...all of which has been developed indigenously. This technology can be easily used in other space programs for civilian applications.

Not sure on what basis you are considering this as not being technologically significant.

The thing about shooting down another nation's satellites in a military conflict - your own satellites are equally as vulnerable. It's like starting a nuclear war.

I certainly hope that among the nations and people who are developing these weapons, they have a number of game theory people who have thoroughly considered all of the ramifications of mutually assured destruction.

In a major conflict, the US and Russia have a number of geostationary and MEO orbit military satellite communications systems which are outside of the reach of any LEO antisatellite weapons (capable of shooting down things up in up to approximately 550x550km circular orbits).

On an Indian specific note, this threat has to be aimed only at whatever Pakistan might put into orbit. At present Pakistan has negligible ability to launch anything themselves, and very little actual Pakistani owned/manufactured/controlled satellites in low earth orbit. But who else can it possibly be considered a threat to?

India is hopefully not foolish enough to think that they could get into a shooting war with China and come out ahead.

These tests ought to be banned by international agreements. This is not an achievement for anybody. It is a travesty.

Then everybody will do it secretly. It's only a travesty when someone starts it; other people have the right to respond to parity with their own.

There's no way to secretly test these weapons.

To be clear, I'm not objecting to the weapons existence. I'm objecting to the tests, which are potentially worse than above-ground nuclear testing. The kessler syndrome, if realized, would permanently destroy our ability to deploy, access, and use space resources.

Satellites are sitting ducks. This feat is as admirable as kicking down a sandcastle on the beach.

We need an international treaty banning this because the detritus produced in the form of hundreds of thousands of new fragments in orbit is one of the largest threats to future space development.
