Bharat Rakshak

Holy Molly!!!!! This is blasphemy. India Achieves Chnadrayaan and Mangalyaan success and IITs can't claim any hand in it, the highest engineering, technological and scientific feat that every engineer/scientist/technologist would have aspired for.

Dr Radhakrishnan, Charmian of ISRO, who actually conceived the idea of Mangalyaan, is from Govt Engineering College Thrissur. Not sure if any IITians are there in Team Mangalyaan.

And here is the other open-source-racist-front-page : reddit:

https://www.reddit.com/r/worldnews/comm ... y_entered/

The racist brishit comments have been downvoted to oblivion. Kudos!

^^ for /r/worldnews that was surprisingly better than usual.

I stopped reading reddit after the Sunil Tripathi fiasco during Boston Bombing. It is as racist a site can get, where the stench of white privilege gets to be unbearable many a times.

But that post on /r/worldnews was awesome. Everyone who said anything remotely negative ended up downvoted to death. The usual /r/worldnews idea of India is the new "snake-charmer" stereotype :-- India == rape.

I tracked that thread from beginning, someone found that the shitposters were typically from China and UK timezones with some American "our navy has the second largest air force" type posts. They were all down voted to oblivion
EDIT: wasn't it the British made component that failed in Mars Express? That should be another reason for all the angst.

Just for comparison .. path that MOM had actually taken during MOI and the path that I had drawn and posted earlier.

My old data ( from Jan status ) must be a real old data but that is what I could grab in public domain.



Major reason for the offset is possibly the time shift .. so Mars is in two possible positions ( they have been hand drawn .. so don't try do draw conclusions .. still working and will post a correct figure in a day or two ).

Well by golly, in that case maybe the Brits should look at it like they are paying India to be "NASA" for them!

SSSalvi, what is the type of grid(like a cube) on the background?

Pitted against these futuristic missions, MOM is primitive but promising. All through its journey MOM has controlled its temperature and cruised in the direction of Mars with very little prodding from Earth. While speeding at more than 82,000kmph, it never lost direction, thanks to the star-gazing equipment on board.

"It's not like driving on a highway, you know," says Alex. "In space, everything around you looks the same." To stay on course, MOM used the star-gazer to look at constellations of six to 10 stars every microsecond and compare them with preloaded patterns. "Distant stars are relatively stationary," he says. MOM continuously matched the patterns and, in relation to the constellations, determined its position and direction. That's autonomy.

Congrats ISRO, late as was travelling

While I was watching MOI live (Or rather waiting for that half an hour or so - answering/discussing some questions form others).. some one asked how long before any indication that MOI is successful.
The question was raised that first 4-5 minutes (from start of rockets - till radio black-out) will there be any data to indicate anything...

I realized (since doppler measurement is quite simple) isro will know something from data collected within those 3-4 minutes. (I did see some of the isro guys smiling and less tense so I was predicting..things are going to go smooth almost half an hour before..)....

I think this is a screen grab.. VERY interesting... difference between delta-V (expected vs actual) of the first 4-5 minutes (240 secs or so).. PRIOR to radio black out...

(IMO , isro and Modi knew, MOI is most likely a success around 7:33 AM (T+17 minutes )...

In any case, I really like this..

Yes I had also commented here that some graph showing expected and achieved data looks to be on the dot. I did not understand the relation between velocity and the orbit until gurus explained it later in another page.

Why still no pics??? Did they find a alien or something they don't want to share.

Yes AmberG, I too noticed that smile .. but that just indicated that path prior to firing was ok ( including reversal in attitude and changeover to MG antenna ) .. probably the guy who was smiling was a communications fellow .

Anyway .. what is life without tension ( small or big )?

I was really furious that the commentator never told about the displays in real time.

They should have handed over commentary job to some tech fellow from control room.

Maybe they forgot to load the film , just joking, before all the jongos jump on me.

Can it take a selfie?

Yes, I did see some kind of relief of happiness on some of the watchers... but at time NO ONE commented about this, and clapping did not happen till almost a half an hour later.

True, one ought to wait till final confirmation, I was just thinking why no one in live broad-cast commented about it.
(And I have not seen too many other news papers commenting about it either... It also seem that delta-V posted on FB page was not exactly on dot - this is why actual orbit is different than predicted orbit... but who cares.)

The colour camera, on board India’s spacecraft to Mars, has beamed back about 10 pictures of the Red Planet’s surface which show some craters.

Indian Space Research Organisation (ISRO) officials said the pictures were of “good quality.” They will be presented to Prime Minister Narendra Modi on Thursday before being released to the press, the officials said.

They have got back ten images. But our PM gets to see them first.

Orbiter sends back first pictures
Ah.. Partha posted it first!

Don't remind me about the broadcast. They were worried more about the launch procedures and stuff when the waiting was happening. They were definitely not watching and commenting on the screengrabs from monitors around them. May be they were waiting for the clapping to start before going 'ak phyrrr..'

ISRO's Mars Orbiter ‏@MarsOrbiter 1m

The view is nice up here.

1st image of Mars, from a height of 7.3 km; with 376 m spatial resolution.

Why it has to be presented to PMO? Too much ribbon cutting. Just release it already.

Oh my God!

There is mention in this forum of 40 kbps data rate reported by dsn station some time back. That must be the picture reception.

Craft health telemetry may be 1 kbps .. ( all these are only assumptions based on some experience ... I may be totally wrong )

Oh great .. you watching onlee !!

( No intended offence bro ) just for fun

7.3 Kms may be some other dimension .. definitely not height

May be the total span of image is 7.3 km?

Resolution for the image is 376m, hope the ones with the higher resolution will be out soon.

prashanth wrote:May be the total span of image is 7.3 km?

the right paraphrasing is, picture as seen as taken from 7.3Km above and not picture taken from the height of 7.3Km

Nah they updated the description. Its taken from 7300 km not 7.3 km as mentioned. That would explain why it looks a little blurred.

Yeah, it can't be 7.3 km since perigee itself is 365 km. It's a pretty good pic for 7300 km.

They had made an error. It was 7.3 K kms ie 7300 Kms and they have edited and corrected it.

Full disc is at approve 80000 Kms.

Yes it seems to be so. Most of the time it is transmitting at 999 b/sec and there was an upsurge to 40 kpbs/sec probably during picture transmission. Wonder why MAVEN sends then a constant stream of nearly 250 kb/s must be a large quantity of data

Probably had to wait till actual deceleration and more importantly stopping of firing was confirmed.During that blackout one cannot prematurely predict till it actually occurs

They released a photo from 7300KM away for the sake of releasing something is what I feel. I hope all izz well with the high resolution images we are supposed to be getting. This delay is making me nervous.

I see no discussion about the imminent arrival of comet Siding Spring and its potential impact on MOM... Any nuggets on this?
