While there may be plenty of racists out there, my friends and I, white, brown, Americans and Indians are all celebrating with beers. Space isn't a province of race. As an ABCD Indian, I love it. Congratulations ISRO and India!

The pictures are expected in the afternoon. I think they will be busy now doing various other things like telemetry, activation of payloads etc.

Congratulations to ISRO for making India achieve unique success by Mars orbital Insertion today. India has become the first country to achieve this in its very first success. Our Scientists, Engineers and technologists in India, who have chosen to study in premier institutes and remained unlured by riches abroad, have contributed to India's great success. They have proved their capability as one of the best, efficient and effective leaders in Science and technology.

About six to ten months (per isro before MOI). I will not be surprised if it lives much longer than that.

No sir. If you look at ISRO scientists the vast majority are not from chi-chi IITs, they largely come from RECs and local engineering colleges. A slap in the face of those who only choose to go gaga over our IITs and publish breathless farticles on how many crores package FaceBook offered some random undergrad.

Ahh, Now I see the reason. Wizaard in Chief has also pitched in. No way MOM could fail. It could only Phail ( expand).
So we may , in due course, send Mahindra Scorpio Mars or Tata Mars Safari to land on its surface.

Well to its credit, BBC's first report was not a DIR.
India's first Mars satellite 'Mangalyaan' enters orbit
Only the US, Europe and Russia have previously sent missions to Mars, but India is the first country to succeed on its first attempt.

Those grapes are sour! :lol: :lol:
Coming back to topic. NASA's Deep Space Network antenna in Canberra - Rooland is receiving the data from MOM right now, data rate of 40kbps , which is far better than the 28.8kpbs we had 12 to 15 ago with dial up for internet access!

I cannot say how happy I am, that finally ISRO has done something that is not routine. I wish that they keep on doing this on a routine basis.

it is well within the requirements.the values will be Xmeters whihc is the mean but there will be X standard deviations rangewhich they ahve not mentioned but it is considered very precise.

vina, the bandwidth is huge! it is multiplexing - perhaps TDM.

ps: I may be wrong in the definitions here.. but what I want to point is the data rate is 40kbps, and not the receiving capability of deep space network.

vina, me no data guru, but you have to calculate the b (bits) as a pulse.. a 1 and a 0 to fit in a cycle in that 2ghz. so you can fit more bits. if you are good in math: http://en.wikipedia.org/wiki/Shannon%E2 ... ey_theorem

I think you have not refreshed your page or it is showing a cached page.
What I see is

24-09-2014
Spacecraft Successfully enters Martian Orbit
Burn Start of Main Liquid Engine Confirmed
The radio link between the Spacecraft and Earth is now blocked by Mars.
Eclipse starts - The Spacecraft is in shadow of Mars
Forward rotation starts
Changed Over to Medium Gain Antenna

Pretty quick we are to deride ISRO arent we :twisted:
Also if you go to ISRO's main page they have a blinking note saying orbital insertion is succesful.
I cannot fathom what is achieved by being sarcastic when a truly great achievement is done .Also I think they are more focused on telemetry, activation of payloads and data capture.
