Mangalyaan Successfully Put Into Mars Orbit
knwny writes: India's Mars satellite Mangalyaan was successfully placed into orbit around Mars early on Wednesday following a 10-month journey from Earth. India thus joins the U.S., the European Space Agency and the former Soviet Union in having successfully completed a Mars mission. It is, however, the only one to have done so on the first attempt. Headed by the Indian space agency ISRO, Mangalyaan was made in 15 months at a cost of just around 74 million USD — the cheapest inter-planetary mission ever to be undertaken.
Could it be they succeeded in part because much of the previous experience? Either way, great job doing it on their first attempt and cheapest.
India looks better producing Scientists and Engineers THAN its neighbours producing terrrorists.
Maybe the Indian's outsourced the work...
European Space Agency was the first to do it right in first attempt. India is the first country to do so, and ISRO, second organization. We can expect to read more on the composition and presence of water by studying Hydrogen and Deuterium (Heavy isotope of Hydrogen with at. mass 2) in martian atmosphere. Mostly the atmosphere of mars would be extremely rare even at the closest point. The Karman line of Mars (the limit beyond which atmosphere is assumed to have ended and space is assumed to have started) should be close to 65 Kms. I'm not sure Lyman alpha camera would be able to compute the presence.
The more information we as a species can gather about other planets and travelling through space can only help us all in the future.
To have achieved this at the cost they have means far more experiments performed and more sensors launched.
Congratulations.

The Indians, unlike their counterparts from an "advanced country", know to not confuse inches from meters
But the US and Soviet Union were doing all this and more in the seventies with vastly inferior technology and far more unknowns. Lets face facts: If North Korea managed to produce an Apple II clone in 2014, you probably wouldn't be saying the west needs to get over their 'patriot peens' and accept Kim Jong-Un as a capable computer builder.
That said, this is a huge step for India's fledgeling space program and I hope that by 2030 or so they will indeed have caught up with the US and Russia.
How can I believe you when you tell me what I don't want to hear?
I suspect that the "true cost" is somewhat higher than the quoted 74M. For instance, how many spares from Chandrayaan did they use? One should always be suspicious of major spaceflight operations that claim unusually low cost or unusually fast times, because most of the time they are leveraging pre-existing assets. For instance, most flight hardware components (computers, radios, antennas) have 2-3 year manufacturing lead times: it takes that amount of time to go through the design review process, acquire the appropriate components, assemble the widget, run it through the shake and bake environmental tests, etc.
If you're doing a first mission that needs, say, 2 radios, and you buy 2 plus a couple spares, and you make it through the qualification program and none fell out, you now have two perfectly good radios sitting on the shelf ready to go. But it's not really fair to claim those as being cost free, nor not contributing the schedule.
However, in general, well done to the Indian team.
Such a good idea that such a thing was done by NASA from the 1960s onwards. Space exploration is a far more global effort than people seem to realise and there is NASA money in a lot of projects from the south pole (plant growth experiments) northwards. For example a lot of NASA money went into Australian based scramjet projects from the 1980s onwards. There's so many bits being worked on all over that place that there is bound to be some Indian involvement.
Because they outsource to themselves at 1/3 the cost of Americans.
Table-ized A.I.
There have been significant innovations brought to the global space efforts by Mangalyaan. These innovations are the ones that cut the costs of the Mars initiative to $75M.
There have been innovations in planning, management and execution. The key ones have been a strategic focus on component reuse and leveraging other ongoing space missions within ISRO to concurrently complete tasks for Mangalyaan (:-) Isro folks hate the nickname). The whole project was planned in detail and completely schedule driven. Mangalyaan took 18 months from Mission announcement to lift-off. http://www.forbes.com/sites/sa...
The other major innovation was in terms of software modelling & simulation of the entire mission. Physical tests were made redundant on a scale never done before - just one prototype was needed. This cut waste, time & costs significantly.
ISRO chose a longer route but the slingshotting technique paid off in terms of far lesser fuel consumption (thus reducing the weight of the space craft) and yet took approximately the same time as the Maven.
Low manpower costs also helped.
I would think the payoffs to the global space community are in terms of cutting edge techniques developed. Collaboration with the Indian industry have helped build next-gen capability which will pay off in the years to come.
The Mom, a Technology demonstrator is a product of Jugaad or Frugal Engineering. The next mission is scheduled for sometime in 2017-2020. More at: http://en.wikipedia.org/wiki/M...
I think part of the intent for ISRO was to collaborate with NASA on future missions. After USA's recent fallout with Russia over Ukraine, I think NASA is keen on finding an alternate partner (and a cheaper one if possible) for its future space missions. Historically ISRO has provided launch services to many European and Japanese satellites.
Amit,
Please do the needful.

Congratulations, India and ISRO. I'm happy about your success, and I wish you well in the future.
Instead of spending billions for NASA to maintain the ISS and other dubious enterprises, why not just pay ISRO some of our small change to do it for us. I bet you they could have put a rover on Mars for less than the cost of the wheels on Curiosity. For the cost of Curiosity we could have a rover on Pluto.
Nice of the PM to visit and sit in on the last stage of the journey, putting science and scientists in the spotlight. Over here (NL) we hardly ever celebrate scientific successes, and accomplished scientists receive less attention and recognition from politicians than sports heroes.
If construction was anything like programming, an incorrectly fitted lock would bring down the entire building...
... I wonder what NASA can do with a budget of $74 million ...
.....
... hmm
Muchas Gracias, Señor Edward Snowden !
A small trivia- Mangalyaan is a Hindi compound word (in Sanskrit like languages, you can join two words) which means Mangal = Mars and Yaan meaning vehicle. A simple and effective name!

Indeed, the Indian PM also tried to put this into perspective vis-a-vis sports wins with the following quote:
"This achievement is far greater than a cricket win"

Agreed- good science by India - congratulations to ISRO for their work. Certainly it may open up interplanetary exploration in the same way SpaceX have been redefining conversations about getting into earth orbit. the NASA Mars Orbiter cost 671 million. I am sure it is more complex, but I am also sure some spaces agencies may be contacting ISRO to ask about using their platform to transport their experiments to Mars as an interesting alternative to NASA's much more expensive option. More options to getting to Mars presumably means it's more likely more spacecraft will be heading that way?
I was just wondering - Since we are putting satellites (a mass m) in space, we are reducing the mass (and hence moment of inertia) of earth. Shouldn't this change the angular velocity of its rotation about its axis? If so, what would be the delta? too small to observe?
Very true. I am pleased one of the stories gives its readers the handy hint that the rocket "weighed nearly 320 tonnes - almost as much as 50 full-grown elephants". Nice to see the media world-wide goes for those handy public friendly measurement analogies to really mess with people's heads. Not sure how many elephants there are to the Library of Congress or a US football pitch however.
It may be more about the price tag than anything else.

now we will have more knowledge about Mars
The final operation began at 4.17 a.m. when the spacecraft's medium antenna was first activated for signals and it was rotated towards Mars at 6.57 a.m.
"The 440 Newton liquid apogee motor (LAM) was fired at 7.17 a.m. and its burn started on dot at 7.30 a.m. as programmed for the crucial operation," a senior space scientist told IANS at the Mars mission control centre here.
Test firing of the LAM for nearly four seconds Monday, nine months and 21 days after it was shut Dec 1, 2013, enabled it burn as intended for insertion.
"The burn was terminated at 7.54 a.m. when the required braking velocity was achieved and the spacecraft was reoriented to point its antenna towards earth for resuming communication with ground stations," the scientist said.
The Orbiter's speed was also reduced by 2.14 metres per second from 22.2 km per second for its smooth transition into Mars orbit from Sun orbit.
The burn took place when there was a solar eclipse on Mars for 15 minutes. As a result, radio link between the spacecraft and earth stations snapped.
"As the accelerometers onboard were programmed in advance, the commands were executed automatically," the scientist claimed.
The eclipse occurred owing to Mars, sun and earth geometry (moving on same axis) five minutes after burn started (7.35 a.m.).
"As the spacecraft entered the eclipse phase, we had to re-orient it to align the thrust vector before firing the engine along with its eight small thrusters to reduce its speed," the official added.
The spacecraft is cruising in an elliptical orbit 427 km from Mars surface (perapsis) and 78,500km away from it (apoasis).
The Orbiter will take 77 hours or 3.2 earth days to rotate around the red planet over the next six months and for studying its surface and mineral composition and scan its atmosphere for methane gas in search of life-sustaining elements.

What version of the Bible is that!?
A lusty one!
"NASA are the ones who trailblazed pretty much everything to do with space exploration" ARE YOU KIDDING?

The U.S. is of course the only country so far to have landed humans on the moon, and it has an impressive list of sophisticated and successful missions.
But to pretend that NASA did all the trailblazing is ignorant.
Funny that, I work at a European university and this afternoon I attended a presentation on scholarship, part of which included a history of scholarship and the university. The highly regarded senior lecturer flagged up Imperial Nanking University, 258AD, as the first real university, and made a good case for it, as does wikipedia.
I think you're arguing that a university is only a university if it follows a definition of what one is according to Western European medieval law: I'd say most people would go with a definition that explores how it matches against educational criteria. Something on the lines of a gathering together of scientists and educators to share ideas, engage in research, and communicate expertise to students with the goal of enabling them to achieve mastery (and in turn teach others), while reflecting on the practices of teaching and learning. The educational model that medieval European universities operated on definitely has predecessors elsewhere in the world, such as China, and I could believe India as well.
That name comes from the Cold War. USA plus military allies (including NATO), then U.S.S.R. + satellites, then the rest as the "third world". It never had an economic meaning.
It cost less than 12 cents per km... taxis in Mumbai and Delhi cost 24 cents+.. per km

I hope Mangalyaan is "disruptive" enough to solve these problems.
