Chandrayaan Updates Please!

[Mikesingh]

What the heck? I've scoured all over the net for updates on Chandrayaan-1 but was disappointed. And the ISRO website sucks! There are no updates there. As of now 25th Oct 1230 hrs, the last one in ISRO's website is dated 23rd!

Typical of our lethargic government departments! Can ISRO wake up to this issue and update their site at least every day if not twice? We need to know the progress of the spacecraft. The silence by ISRO is intriguing! Or are they hiding something from us? Has the Chandrayaan got screwed up that they don't want to post any updates?

ISRO has reached for the Moon, but info on the progress is zilch! :mad: There's nothing even in the newspapers today.

Imagine, a history making event for India and as of today we're as blind as bats as to the goings-on with the mission! :(

i think i am gonna agree to wat he said...i am waitin for an update too....the launch was jes a small part of the mission

[Zvezdichko]

it has entered deep space

We indeed have daily updates!

[himanish.bhattacharjee]

The update says: "The fourth orbit raising manoeuvre of Chandrayaan-1 spacecraft was carried out today (October 29, 2008) morning at 07:38 am IST. During this manoeuvre, the spacecraft’s 440 Newton liquid engine was fired for about three minutes. With this, Chandrayaan-1 entered into a more elliptical orbit whose apogee (farthest point to Earth) lies at 267,000 km (two lakh sixty seven thousand km) while the perigee (nearest point to Earth) lies at 465 km.Thus, Chandrayaan-1 spacecraft’s present orbit extends more than half the way to moon. In this orbit, the spacecraft takes about six days to go round the Earth once.

The health of the spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network antennas at Byalalu. All systems onboard the spacecraft are performing normally. One more orbit raising manoeuvre is scheduled to send the spacecraft to the vicinity of the moon at a distance of about 384,000 km from the Earth."

yaa we need daily updates videos images that show what is going on there .
and these will help us to be informed about the chandrayana

[aarp]

from n2yo, the apogee (308km) and perigee (37,837.6 km) are siginificantly lower than what said in here. why there are so big difference?

Update Oct'31st:

The Terrain Mapping camera (TMC) on board Chandrayaan-1 spacecraft was successfully operated on October 29, 2008 through a series of commands issued from the Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore. Analysis of the first imagery received by the Indian Deep Space Network (IDSN) at Byalalu and later processed by Indian Space Science Data Centre (ISSDC) confirms excellent performance of the camera.The first imagery (image 1) taken at 8:00 am IST from a height of 9,000 km shows the Northern coast of Australia while the other (image 2) taken at 12:30 pm from a height of 70,000 km shows Australia’s Southern Coast.

TMC is one of the eleven scientific instruments (payloads) of Chandrayaan-1. The camera can take black and white pictures of an object by recording the visible light reflected from it. The instrument has a resolution of about 5 metres.

Besides TMC, the other four Indian payloads of Chandrayaan-1 are the Hyper spectral Imager (HySI), Lunar Laser Ranging Instrument (LLRI), High Energy X-ray Spectrometer (HEX) and the Moon Impact Probe (MIP). The other six payloads of Chandrayaan-1 are from abroad.

It may be recalled that the 1380 kg Chandrayaan-1 was successfully launched into an initial elliptical orbit around the Earth by PSLV-C11 on October 22, 2008. This was followed by four orbit raising manoeuvres, which together raised Chandrayaan-1’s orbit to a much higher altitude. The spacecraft is now circling the Earth in an orbit whose apogee (farthest point to Earth) lies at 267,000 km (Two lakh sixty seven thousand km) and perigee (nearest point to Earth) at 465 km. In this orbit, Chandrayaan-1 takes about six days to go round the Earth once. The spacecraft performance is being continuously monitored and is normal.

[Mikesingh]

Thanks for the heads up Himanish! Seems ISRO has started updating their website now!
The images were fantastic! Excellent resolution. But why haven't they received any colour images instead of B/W? The TMC is equipped with a panchromatic camera imaging in the spectral region of 0.5 to 0.85 µm.
That means it covers all spectral bands.

Spectral bands

Blue - 0.44–0.52 μm.
Green - 0.5–0.59 μm.
Red - 0.63–0.7 μm.
Near infrared - 0.76–0.85 μm.

Maybe this was a test image? They’ll probably turn on the juice a little later! Let’s wait and see!

[android]

They must have taken a lot more pictures by now.

Anyone know why they are not releasing more?

Also, why is the video on http://www.isro.org/pslv-c11/videos/introduction.htm of such poor quality?

Unless my PC is broken, the other video is just as bad. Better picture, but mostly no sound.


It is rather surprising that with so much IT prowess an Indian website would be of such poor quality. It's not rocket science (pun intended). It probably harms their marketing too.

chadrayaan-1 is in the last earth orbit.From this orbit it will be absorbed by moon into its own orbit

[Mikesingh]

Further to my post above regarding the imaging of the Moon...

The Chandrayaan's catalogue mentions -- "Terrain Mapping Camera (TMC): The aim of this instrument is to completely map the topography of the moon. The camera works in the visible region of the electromagnetic spectrum and captures black and white stereo images."

But the specs mention that the TMC will image in the panchromatic spectral region of 0.5 to 0.85 µm. That means it covers all spectral bands.

Spectral bands

Blue - 0.44–0.52 μm.
Green - 0.5–0.59 μm.
Red - 0.63–0.7 μm.
Near infrared - 0.76–0.85 μm.

Now what the heck is going on here? Colour or black/white? Can someone elucidate this? Confusion confounded! :(

Update 10/11/2008

The first orbit reduction manoeuvre of Chandrayaan-1 spacecraft which is orbiting the moon, was successfully performed yesterday (November 9, 2008) night. As part of that manoeuvre which began at 20:03 IST, the 440 Newton liquid engine of the spacecraft was fired for about 57 seconds. With this, the nearest point of Chandrayaan-1’s orbit (periselene) from the moon’s surface was reduced from 504 km to 200 km while the farthest point (aposelene) remained unchanged at 7,502 km. In this elliptical orbit, Chandrayaan-1 takes about ten and a half hours to circle the moon once.

It may be recalled that the lunar orbit insertion manoeuvre of Chandrayaan-1 was successfully performed on November 8, 2008 and the spacecraft entered into an orbit around the moon with a periselene of 504 km and an aposelene of 7,502 km.

The health as well as the orbit of Chandrayaan-1 spacecraft is being closely monitored from the Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with crucial support from Indian Deep Space Network antennas at Byalalu. The spacecraft performance is normal.

Further orbit reduction manoeuvres are scheduled in the coming days to take Chandrayaan-1 to its final operational orbit of 100 km height from the lunar surface. After this, the Moon Impact Probe, one of the eleven scientific instruments (payloads) of Chandrayaan-1, will be released to hit the moon’s surface.

If the TMC is in broad visible spectrum why it is not transmitting color pictures?

[Mikesingh]

Hey guys, did you see the first image of the Moon taken by Chandrayaan? It sucks! Looks like a hazy fuzz-ball. The resolution is terrible. My binoculars can do far better. Is it due to the distance or due to ISRO resizing the image?

So is this all we're going to get??? :(

Breaking News!!

Final circular polar orbit of 100km achieved at 1830h IST! At last! :)

Now to look out for the MIP and some good hi-res Moon pics!

Cheers!

[himanish.bhattacharjee]

Here are the complete details with regards to what Mike has mentioned.

Today, Chandrayaan-1 spacecraft has successfully reached its intended operational orbit at a height of about 100 km from the lunar surface. This followed a series of three orbit reduction manoeuvres conducted during the past three days by repeatedly firing the spacecraft’s 440 Newton Liquid Engine. As part of these manoeuvres, the engine was fired for a cumulative duration of about sixteen minutes. As a result of these manoeuvres, the farthest point of Chandrayaan-1’s orbit (aposelene) from the moon’s surface was first reduced from 7,502 km to 255 km and finally to 100 km while the nearest point (periselene) was reduced from 200 km to 182 km and finally to 100 km.

With this, the carefully planned complex sequence of operations to carry Chandrayaan-1 from its initial Earth orbit to its intended operational lunar orbit with the use of its liquid engine has been successfully completed. During these operations, Chandrayaan-1’s liquid engine built by Liquid Propulsion Systems Centre (LPSC), Thiruvananthapuram, has been fired a total of ten times successfully. In its present operational orbit, Chandrayaan-1 spacecraft takes about two hours to go round the moon once.

From this operational circular orbit of about 100 km height passing over the polar regions of the moon, it is intended to conduct chemical, mineralogical and photo geological mapping of the moon with Chandrayaan-1’s 11 scientific instruments (payloads). Two of those 11 payloads – Terrain Mapping Camera (TMC) and Radiation Dose Monitor (RADOM) – have already been successfully switched ON. TMC has successfully taken the pictures of Earth and moon.

The next major event of Chandrayaan-1 mission planned in the coming days is the release of Moon Impact Probe (MIP) from the spacecraft and its eventual hitting of the moon’s surface.

It may be recalled that after its successful launch by PSLV-C11 on October 22 into an initial Earth orbit, Chandrayaan-1 spacecraft proceeded towards moon and successfully entered into an elliptical orbit around that celestial body on November 8, 2008. Since its launch, the spacecraft’s health and orbit have been continuously monitored from the Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network (ISTRAC) with critical support from antennas of Indian Deep Space Network (IDSN) at Byalalu.

[cooded]

well...MIP has an Indian tricolour painted on it...so we will have our footprints on the moon...i am waitin for the high resolution moon pics...

[himanish.bhattacharjee]

India on Friday looked all set to becoming the fourth nation to have its flag flying on the Moon's surface when moon mission Chandrayaan-1 detached the Moon Impact Probe device, which has the Indian Tricolour painted on it, for a touchdown.

The 35-kilo payload will crash land on to the lunar surface at around 2030 hrs IST. The MIP will then start sending still and digital video pictures of the moon to ISRO scientists.

It also contains equipment which will help scientists design a lunar lander or rover for the upcoming Chandrayaan-2 mission.

There's a lot tucked away inside the MIP. There's a device to constantly check it's height as it falls, another to check what the air on the moon is made of and even a video camera to photograph the moon from close range.

Those photographs will help ISRO decide where to land India's first moon rover, a few years from now. The MIP also has the Indian flag painted on its sides a Sanskrit shloka as well.

The MIP will disconnect from Chandrayaan from 100 km above the moon. As it falls, it will send information back to the satellite. Closer to the surface, rockets will be fired to slow down its speed and soften impact. After half an hour of free fall, the MIP will crashland on the south pole of moon.

Former president APJ Abdul Kalam whose brainchild the Moon Impact Probe is says it's his dream to see an Indian astronaut walk the moon.

“The youth of India should consider that encouragement of the youth is the most powerful resource on the earth, above and underneath, India will do it,” he said.

[Mikesingh]

Nope! According to info, the MIP stopped sending signals immediately after impact.

Regarding those two images beamed back by Chandrayaan from the MIP, any idea about the altitude they were taken from? As usual, ISRO has not given this info but just mentioned they were taken during the MIPs descent. I wish ISRO gives more details in future instead of treating all info with a broad brush!

Cheers! :)

[apollonut444]

I have read in Air and Space Mag, that the Chandrayaan spacecraft will be able to photograph the Apollo Sites! Is this possible and true? Sure would be nice to prove that their were landings by Apollo. I believe it as I was old enough to understand this great event! I too was wondering why the pictures are few and far between. Please let me know on this Thanks!:cool:

[Gayatri Shejwal]

Thanks for the update...

[mooniac]

:mad: what a shamefully backward way of releasing 21st century data:

Look at THIS picture taken by NASA's Lunar Orbiter 1 in 1966:

Lunar Orbiter was launched only 9 years after the first ever satellite launch.. sputnik, and look at this image recently recovered from its tape recorders.


http://antwrp.gsfc.nasa.gov/apod/image/0811/earthmoon_nasa_big.png



And look at India's Chandrayaan image releases:
Chandrayaan is launched 41 years after the space age began, and more than 15 years of India participating in spaceflight and also considering the standards of today!!

Now there's a problem!

it's in the the attitude,

the camera on the other hand is pretty good I bet. ;)



Of course its not fair to compare NASA and ISRO

But come on give me a break and make us believe ISRO is LEADING in many fields.. they don't care tuppence that people should know and appreciate it. :rolleyes:

Of course the TMC can! But what are you going to find up there except the area where they landed? Considering the TMC's res of 5m, anything smaller than this would not be easy to identify. The Apollo missions had left some small scientific instruments on the Moon, but these would be difficult to spot unless there were larger than 5m. And there are none bigger than that!

Probably the Apollo Moon buggy? But considering that the frame was 10 feet (3 m) long with a wheelbase of 7.5 feet (2.3 m) and a maximum height of 3.75 feet (1.1 m), you'd still not be able to see it!

Cheers! ;)

[Mikesingh]

What a joke!! Today is the 22nd of Nov of the year of our Lord 2008! The last pic sent by ISRO was on the 15th of Nov! So is that it?

OK, guys!The show is over. Move on! There's not much else going to be coming from ISRO. Especially if they've found those intriguing unexplainable Moon anomalies! Like they say, the top secret U.S. Military space program is already mining the Moon since 1962.

If that be the case, you think ISRO would put out the images of these mining activities in the public domain? NO! You see, ESA, NASA, Jaxa, ISRO etc are all in it it together. No one's going to let the cat out of the bag. If Chandrayaan does find something, it will be conveniently air-brushed like what NASA/ESA are doing with the anomalous images that show artificial structures on the Moon.

Do you guys think I'm off my rocker? Or have I lost my marbles? NO! These are the facts and we will be naive to think otherwise. I have done enough research on this and therefore always wondered what ISRO would do if it found these structures on the Moon? Would they disclose it? NEVER!

So that's it. I think I need to go catch up on my reading since there's nothing more expected from ISRO.

Cheers! And have a nice day! :)

Bullshit. Total bullshit...

Will you ever stop with these silly conspiracy theories?

[Mikesingh]

Bullshit. Total bullshit...

Will you ever stop with these silly conspiracy theories?

Huh? Can you prove it's all bull shit? Do you profess to know EVERYTHING that's going on? Are you even aware that there's a top secret military space program being conducted by the CIA/Mil intelligence/NRO? Other than Cape Canaveral/KSC, Florida, are you aware of the out-of-sight U.S secret space launch facilities at Vandenberg, Kwajalein, Wallops Island, Beale, Poker Flats, Marshall Islands, Alcantara, etc? NO! You don't because otherwise you wouldn't have trashed this as 'bullshit'! And I wouldn't waste my time giving you further details as your mind is closed as a clam! But here's something for starters:

Have you heard of the top secret Black budged programs run by Lockheed Skunk works, Boeing’s Phantom Works, etc? Here’s what a couple of U.S senators commented:

Senators' Comments Suggest Existence Of Secret Space Program
Cryptic comments by two Democrats on the Senate floor about a major program in the fiscal year 2005 intelligence authorization conference report point to a secret space effort of some kind that has been under way for years, but which has been unknown to the public, analysts said.
Sens. Jay Rockefeller IV (D-W.Va.), ranking Democrat on the Senate Intelligence Committee, and Ron Wyden (D-Ore.) both criticized the program without naming it on Dec. 8 during debate on the fiscal year 2005 intelligence authorization bill.
http://www.globalsecurity.org/org/news/2004/041213-secret-program.htm

All bullshit, what?
And have you heard of the secret ‘Shadow Govt’ of the United States?
Some of the important directives/tasks of these departments/organizations under the Intelligence Branch, related to UFOs/Aliens are:

Of course, all this would be bullshit to you. Do some research before branding others as lunatics. There is enough stuff that could keep you busy for a month, but this will have to do for now.

As a parting shot, have you heard of Senator John Glenn, a former Astronaut? Here's what he said on NBC TV, 6th March 2001, whilst discussing the Apollo program, "We only see these things in our nightmares or in the movies, and some of them are pretty close to being the truth!"

Nuff said. I don't want to waste more time on self styled 'Know-alls' like you! Do make an attempt to crawl out of your air tight box of ignorance and try and see what's outside. Though I'm aware that for people like you, ignorance is bliss!

Darn! The self styled know-alls we have to put up with! Gets excruciating at times, what? :(
