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.
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.
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.
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...
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"
