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.
Bring on the usual cry babies !!! ... LOL.
Oh wait...they are already whining and rolling-on-the-floor
What is this? Some kind of a reverse H1-B program??
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
Reminds me when North Korea threatened to launch 10000 tungsten carbide ball bearings. Would it really be a big deal?
At 104 satellites, they definitively "shot their wad" on this one.
Stfu ignorant bastard
They are in full festival mode: India celebrates space shot.
Congratulations team !! .... Well done
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.
Israel and the Gulf monarchies are very very good friends.
Evidence for that is everywhere... I'll get you started with this question:
How many terrorist attacks has ISIS carried out against Israelis?
capcha: reinsert
Bahaut acha hen
Fucking SOB troll doll ...soon he and his band of brothers will roll off the cliff...
peace !
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.
Search 'train electrocution' on youtube for the risks of a high passenger ratio.
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.
There were 29 cubesats and a primary payload on that mission in 2013, all off a Minotaur-1.
Yes, actually. I have two questions:
1) Why do you have to act like such a dick, just because you know something that other people don't?
2) When this "rocket scientist" explained it to you, did he act like a douchebag about it by belittling you for not knowing the answer to this pathetically simple problem?
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.

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.
Your statement about resolution vs diameter of optics is only true for a single image captured at a single time, where diffraction limiting is in play. Take a number of images from slightly different places, or with changing atmospheric propagation (turbulence) and you can do things like blind deconvolution and back propagation to substantially increase the resolution. Each image in the set provides a statistically independent look where each pixel of the image is essentially the linear combination of a bunch of smaller pixels in the ultimate image. Since each image you capture is different combinations of different pixels, if you can calculate what the changes are, you can figure out what the finer resolution pixel values are. Since you're typically looking for edges, looking for step functions is a good way to adaptively figure out the values.
This has been used to, for instance, image the ISS or Shuttle with a relatively small telescope on the ground using a video camera.
It's also akin to using an array sensor to get "sub pixel" position for a spot on the array by centroiding.
Sorry about that Chief.
Its quite amazing how /. is flooded with racist comments on every post related to India. If you feel Indians or whoever are taking your jobs, stop electing the same ideology to government over and over again. Stop electing frauds,liars, war mongers and thieves( or some combination of the above)to power in each and every election.
Wow. It's always funny when you can get a couple of cocky douchebags to argue with each other about how smart they feel everyone else should be.
Think about how many people here weren't born before 1962.
And think of the most effective teachers you had throughout your lifetimes. You were their student and you were learning from them. Did they act like pissy little cunts about it? After all, you should have simply been able to go to the library and look up the information yourself, right? Surely they were most effective when they belittled you for not knowing something,
Assholes.
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.
