ISRO Makes History, Launches 104 Satellites With Single Rocket (indiatimes.com)
neo12 writes: Indian Space Research Organization (ISRO) made history by launching 104 satellites in a single launch. The lift-off of PSLVC 37 at 9.28 am from Sriharikota was a perfect one. In 28 minutes, all 104 satellites were successfully placed into the Earth's orbit. 101 of the 104 satellites belong to six foreign countries, including 96 from the U.S. and one each from Israel, the UAE, the Netherlands, Switzerland and Kazakhstan. According to Times of India, "Russian Space Agency held a record of launching 37 satellites in one go during its mission in June 2014. India previously launched 23 satellites in a single mission in June 2015."
If only the rest of the nation was as effecient as ISRO!
This is great, technically speaking. However, here's a little article from the BBC on the current space junk problem: http://www.bbc.co.uk/news/scie... Just look at the statistics at the bottom of the article.
We've managed to fill near-earth with almost as much rubbish as the surface, the actual atmosphere and (more recently reported) the depths of the sea: https://www.theguardian.com/en...
I love tech, but we need urgently to work on its by-products.
On y va, qui mal y pense!
so, just another 88 spy satellites?
yup.

Not a space junk problem:
1/ They won't stay up for many years, they don't have the fuel to do it.
2/ We know exactly where every one of them is, where they are going and can work out where they will be at any time for weeks ahead within a very small margin of error.
Anything else you want cleared up? I'm no rocket scientist but I had a good one explain the pathetically easy stuff to me a few decades back.
Its a new low for /. community!
Awesome achievement. Trying to imagine the kind of brains behind this feat given the meager financial resources they have to deal with
Congratulations team !! .... Well done
Ah, the new normal. Make a small minded insult and get modded insightful.
The only thing insightful about this comment is we get to see just how small, insecure and partisan this AC is.
We are living the old curse:
May you live in interesting times.....

It's another big history for India by launching 104 satellites through 1 rocket. Congrats to all the ISRO team for their efforts on the successful launch.
The Indians may have "forgotten" to tell the launch customers in those two countries about that..
104 new pieces of space junk to track.
Take Nobody's Word For It.
Bahaut acha hen
88 of the satellites are in an orbit less than 500KM altitude. Due to drag from the thermosphere, they'll gradually slow down and fall to a lower altitude. They'll break up and burn up at about 80KM three to five years from now.
I should have said AT LEAST 88 of them are in the low orbit. The rest of them probably are as well. So no real problem of creating space junk here. They'll be gone in about five years.
Now that you have won the latest pissing contest, why not devote at least some funds to improving the lives of the more than 600 million Indian citizens who lack running water, electricity and sewage? Just a thought, you know, so that the rest of the world will stop thinking that you have a big huge chip on your shoulder.
96 of the cubesats in that clown car in space are American.
Tragedy of the commons all over again.
the preceding comment is my own and in no way reflects the opinion of the Joint Chiefs of Staff
Whenever there's a story / discussion involving India, comments on Slashdot are almost always overwhelmingly negative with "ad-hominem" attacks all around. For example, this discussion thread does not have a single comment discussing the technical aspects of the launch - a launch of 100+ satellites is bound to have some interesting technical challenges which can be discussed. Instead comments are lame jokes about H1Bs and comments on how India shouldn't spend money on space missions. Slashdot was supposed to be a "news for nerds" site, where the nerds can actually discuss technology. It's sad to see what it has degenerated into.
Depends on orbit, but yes, look up Kessler Syndrome.

I don't think the Gulf monarchies have all that much influence over ISIS.
The lack of recent successful terrorist attacks in Israel is the result of an their absolutely paranoid security levels.

Not that I'm entirely biased towards Israel (they don't treat non-terrorist Palestinians the best), but I don't think it's exactly "paranoid" when all of your neighbors have tried to kill you at least once. In most cases, several times. And have one or two terrorist attacks in addition to full out wars. And a couple countries routinely chant death to their entire country, possibly all the inhabitants as well. Though I hear the Iranian President is trying to get "Death to Israel" labels removed from their ballistic missiles.
At some point, "absolutely paranoid security levels" become "probably appropriate, but could be more tactful about it especially when dealing with not involved third parties".
I myself am tired of people who point to things they don't understand and state with certainty that it supports their unfounded conclusions when they do nothing of the sort. This goes way beyond simply not knowing something.
I've really looked at this problem, couple of issues came up
A) Why did they choose Tungsten Carbide instead of Eglin steel. just does not seem as effective
B) unless the design is conical in nature, 30% of Ball bearings are going towards earth ( could be a lot more if it's a ball design or tube design )
C) in any case, upon a Kessler Syndrome happening, space exploration would stop for 25 to 50 years unless someone comes up with a way to clean up space ( maybe a world wide concerted effort with lasers to clear a basic launch path. )
so the next step is for someone to create the clean up device.
if you see me, smile and say hello.

Fair enough then, please point out the errors that I made with those two points.
That is far more productive than grumbling and saying I "don't understand".
Tell me what I do not understand and what the real answer is.
I am an engineer not a rocket scientist so I could be wrong even on something so trivialially simple. Am I? How do you know?
No, you are the upset person. The AC was saying that you were rude in saying that the stuff was pathetically easy.
With the greatest possible respect, since I'm sure you are good at something, most children over ten with access to a television in the Apollo era could have told you exactly what I had written.
I was defending your ire.
Sorry about that Chief.
A) prolly propaganda reasons.
B) depends on deployment mechanism. Imagine a charge shooting the payload like a shotgun in prograde direction. Most of the balls will not descend considerably.
C) it certainly is slowed down a lot and made much more risky. We're not sure about full extent of consequences.

Well they might have shown some attitude when a student acted like they were so sure about something and used examples that didn't support their wild assertions like the previous post just did, but you are ignoring what that post did for your narrative. Not only that, you are also completely clueless about the exchange between me and the other person. We weren't arguing about how smart we think everyone else should be. I defended his ire, but he thought I was attacking his stance and the exchange was to clear that up.
