Chandrayaan 1 mission

ckikilwai · Jan 13, 2008

I didn't found a thread for the Chandrayaan 1 mission, so I'll start one.

In short, India is going to send a probe to the moon, they plan to launch it on 9 April 2008 according to this NASA page:http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=CHANDRYN1 written on 30 November 2007

Here are some links with more detailed information:

Wiki:http://en.wikipedia.org/wiki/Chandrayaan

One of the interesting objectives:
"Produce 3D maps of regions of particular scientific interest at high spatial resolution (5-10 m)"

The apollo lunar descent stage is 4.2 meters wide (without its legs), and is 6 meters high, I think it would just big enough to be spotted.
I hope one of the apollo landing is picked as an scientificly interesting site, so we would finally have proof to show the conspiracy theorist wrong...
...unless India is included in the conspiracy of course /images/icons/smile.gif

With a 5 M resolution of TMC instrument, identification of a 4M object is not possible... except that a one or two square pixcels may have a different radiometric properties that the surrounding area. We may find that that pixcel is different but not know what made it so.. even reflection from a miniscule crater edges could do that. We can't determine the shape of the object.

"We may find that that pixcel is different but not know what made it so.. even reflection from a miniscule crater edges could do that. We can't determine the shape of the object." But if there is a relatively flat terrain around the lander, it shows as a pixel high object right on the spot where the lander should be, then it still some kind of proof the lander must be there.

You couldn't consider it proof. It at best could be considered suggestive evidence. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id. I really, really, really, really miss the "first unread post" function </div>

Perhaps Chinese probe could give better results.

Depending on the sun angle there would be shadows also, which would multiply the diameter of the object. That resolution would probably allow spotting the abandoned moon bases. Even SMART-1 with it's humble camera claimed to have imaged the shadow of the Apollo lander. I remember seeing the image and the caption a few years back, however I could not find it now.

sssalvi · Jan 19, 2008

Yes, Shadow will definitely be a giveaway. ... Old photographs show long shadows of craft,flag etc.

Chandrayaan-1 enters lunar orbit successfully New Delhi:After two weeks of journey India's first unmanned lunar spacecraft Chandrayaan-1 entered the lunar orbit on Saturday evening. The journey so far has been 'error-free'. Initially, Chandrayaan-1 will be circling the moon from 7,500 kilometers away. However, by Tuesday it will cruise closer to the moon early on Tuesday when it makes the transition from the earth's elliptical orbit into deeper space, a top space agency official said Monday. "The liquid apogee motor (LAM) on board will be fired around 5.00 am on Tuesday for about five minutes to make the transition and position the spacecraft at about 500 km from the moon's surface and over 384,000 km away from the earth," Indian Space Research Organisation (ISRO) director S. Satish said. The complex manoeuvres will be carried out from the spacecraft's control room at ISRO's telemetry, tracking and command network (Istrac) in coordination with its deep space network (DSN) at Byalalu, about 40 km from Bangalore. "Additional velocity will be given to the spacecraft to enter the lunar orbit Saturday (November for a rendezvous with the moon. With calibrated firing of its LAMs, it will be inserted into its designated orbit, which will be about 100 km from the lunar surface," Satish said.http://ibnlive.in.com/news/chandrayaan1 ... l?fads=ads

I have done some digging, and there were three functioning spacecraft in lunar orbit  in early 67 (Lunar orbiters 2 & 3 and Luna 14.  The would have risen to four with LO 4 in mid 1967. There probably was never a time when there was more than four, even though LO 5 was launched in late 67, Luna 14 had completed its mission by then.   <div class="Discussion_UserSignature"> Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars Arthur Clarke </div>

These indian scientists need to take a page from that book called politeness and humility...when India actually manages to get more than a couple of medals in the Olympics, I'll be impressed, not until then...contrast this with the chinese, who kept a low profile on bombastic statements when they did the more impressive space walk....http://www.upi.com/Science_News/2008/11/08/Indian_space_probe_enters_lunar_orbit/UPI-30771226195216/ ISRO Chairman G. Madhavan Nair said the maneuver to break free of the Earth's gravitational field and to put the spacecraft in orbit around the moon was "the most crucial moment in the whole mission." "We have done it so precisely that, as far as I know, nobody else has got this kind of precision," he said. "Our precision proves that in competence, our scientists and technologists are quite ahead of the global standards. With this, we have achieved more than 90 percent of the main objectives of the mission."   <div class="Discussion_UserSignature"> ------------------------------------------- "Breathe.

I think that when you consider the fact that their nation was fighting for it's independence just over 60 years ago they should be allowed the right to be enthusiastic at their amazing achievement.

The hardest parts of the mission are now over, launch, cruise & Lunar Orbital Insertion & a damn good LOI at that to boot.It is similar to the NASA Lunar Orbiters in the 1960s. I know thay were over 40 years ago now, but think of the different circumstances. NASA was funded to a reasonable level back then in preparation for Apollo, with the Soviet Union breathing down theirs necks.India, with only a tiny fraction of the funding has pulled off something as accurate, really is a major achievement here. Replying to: <DIV CLASS='Discussion_PostQuote'>Proud   India   proud   ISRO.

Yes Andrew,  Let's  hope for the best  from  all the payloads from various countries.

This is so awesome.  I think we're really entering a new age of space exploration, with so many nations joining the endeavor. <div class="Discussion_UserSignature"> "People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff." -- The Tenth Doctor, "Blink" </div>
