next important date is dec 1 ...blast off from earth's gravity field onto mars

dec 15 - GSLV D5 - as far as i am concerned this one is far far far more important than the mangalayaan protect
in terms of long term strategic development

btw anyone knows is there is a camera on the now orbiting craft sending back pictures of the earth ?
The 15 kg (33 lb) scientific payload consists of five instruments:

Atmospheric studies
Lyman-Alpha Photometer (LAP) — a photometer that measures the relative abundance of deuterium and hydrogen from Lyman-alpha emissions in the upper atmosphere. Measuring the deuterium/hydrogen ratio will allow the amount of water loss to outer space to be estimated.
Methane Sensor For Mars (MSM) — will measure methane in the atmosphere of Mars, if any, and map its sources.
Particle environment studies
Mars Exospheric Neutral Composition Analyzer (MENCA) — is a quadrupole mass analyzer capable of analyzing the neutral composition of particles in the exosphere.
Surface imaging studies
Thermal Infrared Imaging Spectrometer (TIS) — will measure the temperature and emissivity of the Martian surface, allowing for the mapping of surface composition and mineralogy of Mars.
Mars Color Camera (MCC)— will provide images in the visual spectrum, providing context for the other instruments.

A very good article by ET. Read and enjoy !!!

Mars Mission: Marking out our space on the final frontier

In the press conference that followed soon after the Mars orbiter launch, a foreign journalist asked what has now become a routine question: why should India send a mission to Mars when millions are in poverty? Isro chairman K Radhakrishnan told him about the benefits of the space programme, but the journalist persevered. Benefits of the space programme are evident, but not so much the benefits of going to Mars, especially for the poor.

Radhakrishnan then talked about how not going to Mars will make Isro rapidly out-of-date with technology. It is not clear whether all the hundreds of journalists assembled at Sriharikota were entirely satisfied.

The Mars mission is not an isolated mission for the organisation. Isro, or any organisation worth its salt, never plans isolated missions. Every programme feeds into another programme, and technology developed for one mission is used for another. This happens so frequently that it rarely makes sense to focus on individual missions and question their validity. Space technology is as inclusive as any other. The Mars mission will feed into subsequent missions of Isro. For engineers, this fact is as obvious as daylight. However, there are subtleties that are not so obvious to the public, and they need to be stressed.

With the launch of the Mars orbiter, Isro has taken a few step-ups on the complexity ladder of space technology. Learning to handle a complex mission has its spin-offs in every area of life and business.

Isro has yet to master the geostationary launch vehicle and its difficulties, a task that could take several years or even a decade, but it has also to look ahead after the GSLV. Going to the moon or planets bring on a new set of challenges, and the development of a new set of technologies. An organisation that does not develop them will soon fall behind in space technology, no matter how good it becomes on sending satellites into earth orbit.

Even without a geostationary launcher, a class of vehicles all other countries use to send satellites to Mars, this mission was no less complex for Isro than it was for other countries. It is not a trivial fact that two-thirds of all Mars missions have failed. Using a smaller rocket, even when as well-tested like the PSLV, does not make the mission any less sophisticated.

In fact, it has probably made it more complex, as Isro also made it in quick time with very little money. The low energy budget introduced new complexities. The changing weather gave it another dimension.

A large vehicle and its satellite together use every kind of technology imaginable. It needs the right configuration of the vehicle. The PSLV is now a mature design, but consistent manufacturing is always a challenge. So is testing. More than anything else, integration is different and difficult for each mission. A small error, only a millimeters difference in the size of a device, will lead to failure. There is some learning with each new project.

Finally, there is science to reckon with. Isro's mission is primarily a scientific mission. Mars is one of the hottest topics, if not the hottest, in astronomy today. Understanding Mars is key to understanding the Earth, its past and future. Mars may once have had life. Its conditions four billion years ago were good for life. In fact, it may even have seeded the Earth with life. Understanding all this is necessary to design the future Earth. We may one day need to even leave the Earth and live on Mars.

Science does not belong to the rich countries alone. When investing in science, it is hard to pick and choose topics according to utility. No one knows what will be useful.

India, being a large country with a large scientific infrastructure, has an obligation to invest in space science. This is particularly so because Isro's budget is frugal. The entire world can learn from India when it comes to low-cost space engineering. The Mars mission is a drop in the ocean when the total budget of the country is considered. Space has to move on.

Re: Chinese Newspaper on ISRO Mars mission

This article is quite neutral but the real assburned and butthurts are the [edited] British.

The tiny miney island nation can't even manage religious riots in tottenham (such stupid names!) but sends peace forces to Iraq and Afghanistan. These dumbos should start introspecting their failed nation and take their lollypop aid and stick it up their ass.

Never felt this way before but reading and seeing a lot of items with reference to india being a poor country. people really like to complain about isro and that india is a land of poor.

Isro is a congregation of scientists with highly regarded skills and training that have been put together with common purpose and objectives from the same demographics that people point out is predominantly poor.

Having such a congregation in india allows the poor to know they can through hard work archive anything in this wonderful nation. Having such a congregation allows people to focus on education and educating the youth to join such institutions. In fact I add other institutions like ias, ifs, even raw to this.

The past and current great leaders and luminaries of the isro and their backgrounds before joining isro was defiantly not of (only) affluence. The isro recognises people with skills and knowledge. Isro wants people to do well irrespective of their background. Look at the pride in people when they hear the names of the scientists that were permitted to speak by the isro chairman and each one said "I would like to congratulate the team". - brilliant.

India having poor is much more different topic and unrelated to isro. India has enough scams, corruption and ineffective policies that can feed them and change their lives. Some say it's better to keep people poor because it's easier to administer them. Some say we need more people like those in isro to be in politics.

But that takes away from the point and the Mars mission and that is - Through hard work and dedication anyone can achieve their dreams be it poor be it rich. And the [x] million of poor in india I know what they were thinking today if and when they saw those beautiful flames light up the pslv c25 ... Aim high anything is possible in our great nation that archived this on its own.

ISRO Job well done. Congratulations. Next bang that GSLV in shape the nation is with you.
ive liked your post

you have brought up at least one v important point which ive hardly heard elsewhere

that the poor can have something to aspire to - prime example -
our past very popular president Abdul kalam -
who started life as a very poor news paper delivery lad -
and look what his tenacity contributed , not only
to himself , community but also nation !

secondly we need to ask all those mainly European hypocrites
is there no unemployment in euriope ?
are there no families losing homes?
are there no old folks sleeping at night in the extreme cold in the outdoors ?
are there absolutely no poor in their countries ?
we all know the answers to those many questions

europe is having massive unemployment !!
especially those graduating from universities and polytechnics
but also massiive general unemployment
it is easily seen on a daily basis

then why is the euro space agency still in existence
then they should disband their space research
until all their poor are taken care of !
by their very own "logic"

besides that it is Indian taxpayer
who shall determine where their tax payments shall go -
not foreigners

and if like the brits , they want to withhold their "aid" -
( where they were to give 200 million to india and in return expected
a 10 BILLION defence contract in their favour - and got annoyed
when it didnt go to them )

that is their idea of "aid " ??
- so i say to them - you decide what you do with your money
and we decide what we do with ours

on another issue ,
besides GSLV being very important , i now upon having had opportunity to reflect
i now think that it was very SHREWD of isro chief radhakrishnan and teams
to cash in on teh mars opportunity, besides the gslv launch in the same time frame

hope the scientists can stand up to the stress
and i belive they can

it truly will be a very great jai hind
if they also successed with gslv

Re: Chinese Newspaper on ISRO Mars mission

^^ some more facts to it:

The movie "Gravity" cost more to produce than the mars mission :D (graivty cost 100 million$)
The cost per Kilometer is 12 rupees. Same as auto fares in chennai!!!
how come you know the fuel cost thats used for the mission.obviously they wont use petrol...it is liquid hydrogen as fuel(not sure)

Re: Chinese Newspaper on ISRO Mars mission

Their aid is just fraction of what they stole from us. Instead of giving money if they send back all Indian doctors, scientists and engineers to India then it will be more beneficial for India. We are not desperate for your help.

Go Pakis Go, Go Arabs go.

Will Isro Mars mission start an Indo-China space race? | Firstpost

Indo-Chinese competition may start in space.
the money seems to go to evangelist missionaries rather than govt projects....
not for building a nation

neither china nor India are foolish to enter in to such a costly race..both countries will spend according to their interests only

Re: Chinese Newspaper on ISRO Mars mission

Next Time we should spend some money on equipping the Arge ntinians. Every time we do something path breaking, we should put aside one percentage of the money and spend that on equipping the Argen tinian army. So next time when the Bruttish speak something we should allow the Argen tina to reply aptly.I would like see their prized QE class carrier to be sunk by a battery of Brahmos missiles off the Falklaaaanddss coast...

Then I will liek to send the R s S with a Aid package to help the poor butt hurt Butrish.

India is quite capable of sending a rocket to Mars and fighting poverty at the same time

This morning, India successfully launched a rocket to Mars. Christened Mangalyaan, or Mars vehicle, the rocket is part of a scientific mission that cost a grand total of Rs 4.5 billion, or $73 million. In terms of the space business, that's a bargain. By contrast, NASA's next Mars mission will cost $671 million and do the same thing as India's craft: orbit the red planet collecting data.
+
The secret to India's low-budget space program is a simple one: operating within constraints and without luxuries. The Indian Space Research Organisation (ISRO) adapts what technology it can, strips out costs wherever it can and is staffed with modestly-paid yet incredibly hard-working scientists, explains the Economic Times. It is willing to take more risks, for example by building just one physical model of its craft compared to the three employed by NASA in case one fails. And it sets tight schedules to reduce costs even further.


Won't somebody please think about the children

Mangalyaan is an impressive achievement, both scientific and budgetary. But as several news reports have noted, India remains an extremely poor country with many millions still going hungry. One piece on a US site, headlined "India Swears Its Redundant, Mega-Priced Mars Probe Is Totally Worth It," is explicit: "How does a country with one of the lowest development levels in the world justify spending on a space program?" This is as familiar and predictable a formulation as the articles by foreign correspondents that begin by calling India a "land of contrasts" and note with wonderment the sight of slums and great luxury apartments existing side by side.

ISRO's founding father addressed this criticism several decades ago:
+
There are some who question the relevance of space activities in a developing nation. To us, there is no ambiguity of purpose. We do not have the fantasy of competing with the economically advanced nations in the exploration of the moon or the planets or manned space-flight. But we are convinced that if we are to play a meaningful role nationally and in the comity of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.


Bangalored

Indeed, India's space research and other advanced technological efforts are what birthed its technology industry. Bangalore did not become a tech hub simply because of its pleasant weather and lovely gardens. It is the home of ISRO, the Defence Research and Development Organisation, Hindustan Aeronautics Limited, and other high-tech industries that created an environment for and pool of engineers.
+
Moreover, the $73 million India spent on Mangalyaan is hardly snatching food from the mouths of starving babies. Two months ago, the government signed into law the Food Security Bill, which will provide roughly 800 million Indians with subsidized food and cost just under an estimated $20 billion every year. Whether you think that the bill is an outstanding piece of humanitarian legislation or a colossal scam that will only enrich middlemen and bureaucrats, it is impossible to argue that Indian government is splashing out on sexy space rockets at the expense of the poor. Mangalyaan costs less than 0.4% of the bill's annual budget.
+
Questioning a poor country's decision to launch a space program also implicitly ignores the fact that rich countries have poor people too. In 1962, President John F Kennedy declared to Americans that "we choose to go to the moon." That year, 38.6 million Americans, or 21% of the nation (Excel file), lived below the poverty line. Last year, it was still 15%.

Mars Mission: Isro successfully completes first midnight manoeuver

ISRO successfully crossed its first milestone by completing the midnight manoeuver of Mars Orbiter Spacecraft early morning today.

ISRO officials said that the first orbit raising manoeuver of Mars Orbiter Spacecraft, starting at 01:17 hrs on November 7, 2013, has been successfully completed.

The milestone was achieved on renowned Indian physicist C V Raman's birthday.

The Mars Orbiter Mission (MOM), which was launched on November 5, was parked at an orbit of around 250 by 23,500 km.

ISRO officials said there would be five firings of the 440 Newton engine, which is on board the Mars Orbiter PSLVC25, to gradually increase its apogee (point furthest away from Earth). The first firing took place early morning today.

The orbiter has to acquire the required escape velocity to leave Earth, and this will be done by gradually firing the 440 Newton liquid engine during its one month around Earth. In the sixth firing, it will escape from Earth's gravity.

This is planned in a series of midnight manoeuvers (a.k.a Earth Bound Manoeuvers) in which MOM's engine will be fired in a direction tangential to Earth while MOM is at its closest orbital position to Earth.

The six ellipses represent the various orbits of the spacecraft around Earth and the outward trajectory represents the Trans-Mars Injection Manoeuver. The fire thrusters of the orbiter to increase its elliptical distance around Earth were scheduled on November 7,8,9,11 and 16.

Thereafter, MOM will mainly be under the influence of Sun's gravity. MOM will have a rendezvous with Mars in September, 2014, said the officials.

"Ever day and every thing is crucial in this mission," said ISRO's spokesperson.

The Focus shifts to ISTRAC!

With ISRO's Mars Orbiter Mission Spacecraft already placed in its parking orbit, the action has shifted to ISRO's Telemetry, Tracking and Command Network (ISTRAC) in Bangalore.

ISTRAC is a collection of several state-of-the-art ground based stations including the 18 m and 32 m Antennas of Indian Deep Space Network (IDSN), the Indian Space Science Data Centre (ISSDC) and the Mission Control Centre (MCC).

ISTRAC will be employed for Monitoring, Commanding, Navigating and Controlling the spacecraft throughout the Mission.

Between November 7 and December 1, ISTRAC would progressively stretch one end of the ellipse (at the apogee or farthest point from Earth) in six moves, called orbit raising manoeuvers.

The crucial day will be on December 1, 2013 at 12.42 am, when the spacecraft would start its long and difficult voyage towards Mars for almost 300 days, under the influence of Sun. The Orbiter is expected to reach Mars on September 24, 2014.

But why no GSLV?

Many experts, including former Isro chairman G Madhvan Nair, have criticised the Isro's decision to launch the Mars Orbiter Mission on the PSLV pointing out that the GSLV would have been a better bet as it could have carried more payload.

However, Isro chairman K Radhakrishnan defended the move, saying "Initially, nine payloads were designed for the mission and four were not worthy for flight. So we could use only five, and in that sense, there is no compromise... The important thing was to make use of the launch window." He, however, agreed that the GSLV could have put the satellite into a higher orbit and could have saved one orbit raising operation.
