Sify News: Chandrayaan's orbit raised

Thiruvananthapuram. Cool name. It's the capital of the state of Kerala.

There's a nice diagram of the burn sequence, though it doesn't have the dates or times:

I wish India would focus on its overpopulation and social injustices (especially to its "untouchables") issues before going to the Moon.

O yes? How would you fix overpopulation then?

Edit: On second thoughts, best not to hijack this thread. Could you start another one please, Antares7? I'd love to discuss this with you...

OK. I see we have to transfer our audio countdown technology to India. It's a tip all you amateur counterdowners can use, too. I learned it in a studio TV control room.

This video of the launch (YouTube video, about 30 seconds) shows a countdown clock, with resolution in thousandths of a second (well, to the grosser resolution of slower video frames), with an audio countdown in seconds.

Now, maybe it was simply edited wrong. It might have been produced by an amateur who didn't know better, but a professional video editor should know how to do countdowns. And, maybe the anounced countdown was for liftoff, and the timer was for ignition. I don't know. I can think of a dozen excuses. (This is just for fun.) So, maybe ISRO already knows this. But... maybe the ISRO announcer was unprepared, or overly excited.

When the clock turns over, say, from 4.000 to 3.999, an untrained brain, seeing the units digit change, thinks that is the time to say, "3." But it's not. That's when one should say, "4."

Very common error. I've seen it a thousand times.

If you don't say it right, when the clock goes from 1.000 to 0.999, you wind up announcing, "0!" while in reality there is still a long second to go before actual zero is reached. If anyone is actually taking action on your words (I doubt it, in the professional rocket-launching business), they might do so too early.

Handy wallet guide. Clip and save! ------ 8< -------------------------------

Countdown clock transition / Time to announce
4.000 -> 3.999 / "4"
3.000 -> 2.999 / "3"
2.000 -> 1.999 / "2"
1.000 -> 0.999 / "1"
0.000 -> +0.001 / "0"

Coulda said much the same about the US in the 50's. And Russia & China...well...less said, the better.

If you want to wait for the day when we can all sit around and sing Khumbaya, ya might as well get used to the idea of never getting anywhere.

I guess that was Earth Burn (EBN) 3, though a mission sequence diagram says the result would be 200 000 km apogee. Maybe that was old info. I'll go with the news.

Up next in a couple of days, when Chandrayaan 1 loops back near Earth, is EBN4 which might yield roughly a quarter-million km apogee, and then, in some more days, EBN5 to head to the Moon.

black and white? not colored?

still nice, and amazing

It says here (my bold):andReally smart idea I think, but is the article correct? Has anyone else flown a 3D camera in space before? 01101001?

I don't recall a design like that -- but I don't recall much about all the cameras that have been on spacecraft. Certainly we've had 3D imaging, but the systems I can recall used two cameras, or a single camera on two different passes.

This design is different in that there is one camera with 3 separate viewing ports and mirrors to guide the light in.

Ah, thanks. So it might be the first 3D camera at least. That's pretty cool. I was looking at the graphic in that article, seemed like a smart design. Thanks.

ISRO has stereo imaging earth observation satellites, but I think they use two cameras. Here it is achieved by single camera looking at a single spot 3 times in a orbit during at different angles.

Yeah, I saw that. Same spot, three different angles, three different times (sequentially). It'll take some nifty software work to sort out! But I'm sure they're used to that. Interesting design.

CARTOSAT

As 01101001 pointed out it uses two cameras to produce the 3D images.

The burn is scheduled at 17:30 IST (1200 UTC) Nov 8.

Seem comparatively similar to the HRSC on MEX.

There is a lot of Apollo 3D shots, if you take the time to look at the Apollo archive. Also, because of settling during landing that caused a shift in position, stereographic shots were taken with Luna 9.

Answering my own Q, according to a recent newspaper profile of G Madhavan Nair, the ISRO Chairman (I've lost the paper, sorry!), he decided only two months ago to change the flight plan, from a direct, Apollo-like course direct into Moon orbit, to the actual incremental one, to allow fine tuning of the direction. Full marks for such a redundant design that this was possible, no marks for foresight.

John

Congrats For making the Chandrayaan to enter the Lunar orbit !!
For the first time its time to talk perilune and apolune!!

As far as above statemenent of Madhavan Nair goes I think, India does not have rocket to put satellite in Apollo like orbit. Proof India does not have ICBM's ;-)
Mr Nair did you came to know about this only two months before launch???

I'm glad you mentioned ICBMs. Because I went looking. You're technically correct:
Agni, an Intermediate Range Ballistic Missile
Surya, an ICBM under development

Only technically.

Anyway, that isn't why I'm glad. While investigating, I found this: That's huge!

This method seems conceptually similar to a rumour I'd read about: many years ago the Russians discovered a way of reducing high velocity drag by firing lasers into the air-stream. I'm preparing a thread as we speak. I bet you all can't wait...
