Chandrayan-1 moon mission
Re: Chandrayan-1 mission launched succesfully
Some updates about Chandrayaan-1:
1. The Terrain Mapping Camera ( TMC ) , one of 11 payloads on board Chandrayaan,has been capturing images of the Moon since November 13 from a height of 100 km from the lunar surface. They will be processed by Monday,17th.
2.On Sunday , The Hyper Spectral Imager (HySI) would be switched on. It would create a mineralogical map of the lunar surface
3. The MIP, ( 2 images of which have been published ) is not really a video camera. It is a still picture camera clicking at high speed. It has actually returned about 15,000 images over the course of the 25-minute descent. This may be converted to a slow framed video later.

indeed, good for deep space probes and RORSATs imo.

Re: Chandrayan-1 mission launched succesfully
The Hindu WAS (and probably is) a gem of a newspaper, until N.Ram took over. Its magazine sections were some treat to read. They used to have "Science & Technology" on Wednesdays, "Open Page" on Tuesdays, "Young World" (I forget the day)....Unfortunately its left sympathizing behavior has tainted some of its news reporting and opinions.

even in mid 80s the Hindu had superb technology supplements that
would put NYT to shame today. and very neat diagrams and charts
to back it up. me being class5-10 couldnt grasp all of it, but sure
was good s*** and backed up my interest in engineering.
and SportsStar mag iirc from same group had the best paper quality
(with Frontline) and the best sports pix.

Fair question. There is some doubt. The low cloud cover is quite massive, as seen in this video. http://www.youtube.com/watch?v=na_EzQoc ... re=related But once it broke that cloud cover, it is quite clear. By contrast, in the first video above, the low cloud cover is not as solid. So, the possibility is that the angle from which they took that video did not have as thick a cloud density (only low clouds were thick). But I am not sure. If you compare the 2 videos time-wise, you see an event (separation?) at 2:00; and in the second video (the one with thick cloud cover) at 1:54 ; both times are +/- 1 second. In the first video, the launch can be visually detected at about 12 seconds into the tape. So, timing of the event = 2:00 - 12 s = 1min 48 s. In the second video, the event is at 1:54, and the visual indication for liftoff is about 8 seconds into the video. Event timing= 1min 54 s - 8s = 1:46. So the timing of the event in both cases is close. I dont know if the stage separations occur at the same instant for a specific type of rocket- if they do, then a case could be made that the first video is genuine- though I still see a discrepancy of about 1-2 seconds but 1 second is the least count (! haha, remember the classes on vernier calipers and screw gauge?!) on video time.
On a different note, (for a different post) regarding the point about ESA not being a country, yes, but a) Europe does cooperate on space activity and will continue to do so in future, and b) they did get there in a controlled impact, and so they rightfully deserve to mentioned 3rd in the list after USA and USSR.

Re: Chandrayan-1 mission launched succesfully
For those who want to check on the superb quality and resolution with which the TMC is capturing the Moon, check this comparison..
The Moretus Crater
CY 1:
http://www.isro.org/pslv-c11/photos/ima ... region.jpg
(Only part rim of Moretus visible because of resolution, Moretus is 117 kms dia)
Previous NASA:
http://www.lpi.usra.edu/resources/lunar ... .shtml?277
http://www.lpi.usra.edu/resources/lunar ... .shtml?317
(You can see the crater marked in the middle)
The Toricelli Crater: (22 kms wide)
CY 1:
http://www.isro.org/pslv-c11/photos/ima ... region.jpg
(Part visible again)
NASA:

wow!~... we should name this bright crater after some Indian name. They do it, before us.. we should start naming objects we see in moon.
come on folks help here..
How about calling it "Anuraj!" Crater ?
Q1. that shining surface on the crater is fantastic, like a mirror. what would be surface like? any metals?
also, looks like 4/5 toe tips of a giant feet to the right of the shining crater. Lets call it "Chandra-pada" ?
cheers!

Re: Chandrayan-1 mission launched succesfully
No doubt features would be named as such. Traditionally moon craters are/were named after astronomers (aka scientists) and there are already craters/features named: Raman, Mitra, Saha, Sarabhai, Bhaba (this is a smaller crater at the rim of the crater called 'Bose' ) , as well as names from epics like Sita, Krishna etc.. and also astronauts like Chawla ((All of these are on the moon)wow!~... we should name this bright crater after some Indian name. They do it, before us.. we should start naming objects we see in moon.

In past, one of the "recognization " given to young scientist (like Intel finalists) is to name astronomical bodies (minor p.lanets) after their names.

Re: Chandrayan-1 mission launched succesfully
I would suggest that the point at which MIP struck the moon should be named after Dr.Kalam like "Kalam Point"
Re: Chandrayan-1 mission launched succesfully
AFAIK - there are some guide lines for naming, but generally "Discoverer" proposes a name, and it becomes recognized (official) if approved by IAU.Kakarat wrote:I would suggest that the point at which MIP struck the moon should be named after Dr.Kalam like "Kalam Point"
(Normally any political or Military leaders name is not accepted (unless the person is dead for 100 years) but Kalam as a scientist should be fine.
(BTW - small minor trivia item - there is a minor planet named "Amber" after some one .. who I know pretty well)

Also was comparing the resolution with the best available resolution of Toricelli. CY1 is ace! Here's the best resolution photograph so far..

A video here, some factual content is not accurate, orbits, 1000 km etc..but it's a nice video to see. Very well made.

O/T but Sumishi - NO, its not me. As I said, it is someone who I know..very well ... (Sorry for obvious privacy reasons no speculations etc, (Harbans your info is about a different minor planet (It is not ref # 21431) .. (If you are looking at the alphabetical list of minor planets, see the name just below what you looked at - MP was named to recognize the person's own achievements.... but let us leave it at that ..)
Re: Chandrayan-1 mission launched succesfully
naming for example can go by expression as well, those scientists did a "holy cow" over phoenix lander on mars, named it "holy cow".
http://apod.nasa.gov/apod/ap081112.html
btw, look at this: http://www.isro.org/pslv-c11/photos/ima ... region.jpg
the larger (faced) crater and the one on the "shoulder" both seemed to have something (liquid?) flown out towards the center (merge), and left a flowing cleft mark.
I would call this picture "Bamyan Buddha crater".

Re: Chandrayan-1 mission launched succesfully
If someone have suggestions for name, I suggest (and I am sure it is being done) that they contact ISRO. etc..
The policy for naming for any of the moon’s feature is:
BTW, if you are curious and want to see names already taken – here is one list of names of Lunar craters. (And hence you can check out, say where “Raman” crater is)
http://www.lunarrepublic.com/gazetteer/crater_a.shtml
(You can see the names of other – existing – features too - and in atlas part - you can see where CY1 has landed etc.. )
The policy for naming for any of the moon’s feature is:
(So one sees names like “Ravi” for small craters and “Bose” etc for larger craters) .Large craters: Famous deceased scientists, scholars and artists;
Small craters: Common first names.
Catenae, Dorsa, Rimae: : Feature names derived from nearby craters.
Lacus, Maria, Paludes, Sinus: Latin terms describing weather and other abstract concepts.
Montes: Terrestrial mountain ranges or nearby craters.
Rupes: Name of nearby mountain ranges (terrestrial names).
Vallis: Names derived from nearby features.

I am more for organic names..rather.
Re: Chandrayan-1 mission launched succesfully
wonderphool onlee to have my family name assigned to crater!
Satyen Bose was my grandfather's teacher and my mother still remembers meeting him as a kid, as being a man with a very deep gravelly voice and serious demeanor.
I think ISRO should name a feature (which allows non-deceased names) after Kalam .....not only for his selfless contributions to India as a scientist but also as a visionary, a man with principles and a human being.

Well...the tittle at the begining of the video says C11 and it does look like a dawn/dusk launch. Do not remember any other pslv dawn/dusk launches in cloudy weather.
It may be possible to tell for sure from the length of the strap on's ( relative to the core) as Pslv-xl strap on's are longer.

Meanwhile any idea when they will release more pics and the MIP video. They said they would release it today.
I got the Toricelli C (Northwest of the Toricelli crater) pic coinciding with the Equator Picture that ISRO released. However due to the much higher resolution that CY is mapping could not coincide the Moretus crater pic of NASA with what ISRO has put up. IF anyone has any info on that please do put it up.
Meanwhile i wish ISRO would give a little more details Long/ Lat etc of the pics they post. Wish they don't do what JAXA and the Chinese have done. I already appreciate the fact that ISRO appears much more open and transparent and wih they continue to be so.

Raghunathji thanks a lot! That is indeed the best and highest resolution video imagery available of the Moon i know off! However what happened to the MIP crashdown imagery ISRO was mentioning. Anyways ISRO has already produced so much for us, so much more already than recent missions..i do hope they keep feeding us more. But this imagery i see is again flyover the "Moretus" crater rim on the left. Why does it not match with part of the NASA pic of Moretus crater here?

This allows you to open it directly in Windows Media Player and watch it full-screen
Despite the huge zoom of going to full screen, it will give you an excellent idea of the quality of the images, as well as the rate of imaging (look to the right for the frame counts)

An interesting piece from the above interview with Hoagland (I didnt now that he was a nut case but he quotes the Vedas):harbans wrote:India's first Moon Mission and the Rediscovery of ancient ET artifacts..
http://www.americanchronicle.com/articles/81702
M.S.: Do you consider India as a possible contender for informing the world about artifacts on the moon through satellite imagery?
R.H.: Definitely, yes. The Indian Vedas preserve remarkable hints of the ancient, sweeping, high-tech history of all humanity -- from the distant era when both the Moon and Mars (and many other bodies in the solar system) were once inhabited ... by our own great, great, great ancestors. If there is to be "disclosure" of these long hidden truths, there would be no more fitting "messenger" than India ... if they are "allowed" to make them public by other geopolitical forces acting on them at this time. Obama's curious, public "singling out" of India's new Moon mission ... weeks before he was in any position to do anything about it ... is a very intriguing sign of what could happen in the coming months ....
