Unless it somehow advances to the point of being foolproof, that seems a little worrying from a Kessler syndrome standpoint.

It's not big satellites in controlled orbits that are a major problem from a space junk standpoint. Mostly it's the smaller fragments that are the problem, which outnumber satellites by a huge margin. Besides which, the easier it would be to launch satellites into orbit the easier, and cheaper, it would be to launch programs for cleaning up debris and abandoned satellites. In fact, if launch were significantly cheape…

I read an article forever ago that a de-orbiting system could be as simple as a bunch of wires being shot from the satellite to the earth; gravity would tug on the wires and slowly pull the satellite out of orbit.

What is even more commendable is that it was done pretty cheaply [1]. Granted the capabilities of some of the other craft are different - but not THAT different. Add to this the fact that this was a success in the first shot - getting a craft from the Earth to to Mars Orbit correctly in one shot on a meager budget is indeed a stunning success for ISRO.

It does have less than 1/4 of the payload (by mass) of NASA's MAVEN. So it's not like NASA's much higher budget didn't buy them anything. Still, it is a wonderful thing to show that you don't need NASA sized budgets to do interesting things in space.

> The entire internet community came together to deride this why the persecution complex ? Yes there was criticism, but there is always criticism of everything on the internet. Another proud Indian.

Proud: "feeling deep pleasure or satisfaction as a result of one's [b]own[/b] achievements" By definition neither you or sidcool are proud (unless you actually/literally helped the project), you must be looking for a different word, perhaps pleased

I believe he /literally/ helped the project by paying his taxes on time.

The government plays ads on local TV channels urging citizens to pay their taxes on time and that the money helps government execute projects like this.

Well Done! But $74 Million could have been spent giving toilets to Indians, so that don't have to shit in the streets.

Well Done! But the $700 billion US defense budget could have been spent giving basic health care to Americans, so that don't have to go bankrupt whenever they fall ill.

I remember when in 2012, the then PM of India had declared this project. The entire internet community came together to deride this, saying it's not possible in a couple of years and that India had better feed its hungry etc. I am a very proud Indian today. This achievement, like other by humanity (LHC in particular), will encourage me to push myself towards greatness.

> “When you call yourself an Indian or a Muslim or a Christian or a European, or anything else, you are being violent. Do you see why it is violent? Because you are separating yourself from the rest of mankind. When you separate yourself by belief, by nationality, by tradition, it breeds violence. So a man who is seeking to understand violence does not belong to any country, to any religion, to any political party or partial system; he is concerned with the total understanding of mankind.”

I guess it really is a huge(proud-able) accomplishment to pay your taxes on time

NASA - Do you want to Outsource? ;-)

I am sure they eventually would. If not NASA, then other countries would definitely do so.

Chandrayaan contained payloads from NASA and ESA already. PSLV has sucessfully launched satellites from various countries.

It has already begun.

ISRO's Mars mission is the cheapest so far, just 450 crore i.e Rs 12 per km, equivalent to Auto fare .Truly Indian

T-h-a-t is awesome if it is true. Soon spacex will outsource satellite building to india as well :P

Auto fare may be a bit more, because they charge 1.5 times the metered cost when running at night :P

proud:feeling deep pleasure or satisfaction as a result of one's own achievements, qualities, or possessions or those of someone with whom one is closely associated. you conveniently left the second part "or those of someone with whom one is closely associated."

well then the question is what "closely associated" means, if by being Indian, Chinese, black, white, orange, etc "closely associates" you with them (that group?) then anything does, the fact that we all wear clothes for example, we belong in a group that shares this idea, which then closely associates us, making the word meaningless

It doesn't make the word meaningless at all. There are many orders of granularity in "close association" and the diversity of the usage of the word reflects this. For example a google search for "proud to be human" turns up nearly a million hits. The phrase "proud to be alive" returns yields almost two million. Even "proud to be from the milky way" returns six results.
