Oh wait... that would be the Force... Dark Side of the Force ...
As to the Moon there is NO DARK SIDE...
You had almost made my heart skip a beat there, putting into question my "astronomical" skills, till I came upon the second and the third lines.
INTERVIEWER: You have a good equation with Mike Griffin, NASA’s chief administrator. There have been several international projects, such as the Large Hadron Collider, the International Thermonuclear Experimental Reactor and Chandrayaan-1, with several countries participating in them. NASA has announced that it will establish a base on the moon by 2024. Will NASA invite India for cooperating in setting up such a base?
NAIR: As far as planetary explorations are concerned, we have a good equation with NASA, the ESA, the Russian Space Agency, and so on. I, for one, strongly believe that international cooperation will be the norm for the future. Definitely, we are in touch with NASA as far as their plans for a base on the moon is concerned. We will not get such an opportunity [again].

To enable the satellite to be completely captured by the moon, and thereby make the earth’s gravity irrelevant, the satellite would have to be slowed down. And this important operation will be performed when it is about 500 km from the moon, above the lunar north-pole. This is expected to occur around 1730 hrs on Saturday. At this point, the satellite’s orientation will actually be earth-facing. Also, significantly, the orbit will no longer be a closed elliptic one; it becomes an open hyperbolic one. So, if velocity reduction is not achieved at the designated time, the satellite will escape from moon’s gravity and be irretrievably lost in space. Thus, this operation is extremely crucial.
...
... A little before the satellite approaches the lunar north-pole, its orientation will be turned around to ensure that its new orientation is exactly opposite to its velocity vector. The firing of the retro-rockets is expected between 1730 hrs and 1800 hrs. Within an hour, one will know if the manoeuvre has been successful.
Once completed, the orientation will be maintained such that the solar panel continuously faces the sun to generate maximum power. It will be similarly turned around every time a velocity reduction operation is to be performed. Four more velocity reduction operations are required to be carried out, twice at perilune and twice at apolune, to bring it into final pole-to-pole circular orbit of 100 km radius. The satellite will attain its final orbit on November 15.

According to space experts, LOI is not without danger because it means traversing through an area in which the gravitational forces of the earth and moon nearly cancel each other out. Consequently, even a small deviation could send the spacecraft into a crash course towards the moon or earth — or on a path leading into deep space. Experts recall that about 30% of unmanned moon missions of US and the former Soviet Union failed during an LOI.

And Sentinel, you put up a very valid point regarding the images. B/W or color? ...

"The lunar orbit insertion (LOI) will start around 5 p.m. and last around 800 seconds," ISRO spokesperson S Satish told PTI here.
Chandrayaan enters lunar orbit
8 Nov 2008, 1715 hrs IST, TIMESOFINDIA.COM
Chandrayaan-1 has entered the lunar orbit successfully. The spacecraft will last around 800 seconds in 7,500km x 500km elliptical orbit around the moon.
Chandrayaan-1, India’s first unmanned spacecraft mission to moon, entered lunar orbit today (November 8, 2008). This is the first time that an Indian built spacecraft has broken away from the Earth’s gravitational field and reached the moon. This historic event occurred following the firing of Chandrayaan-1 spacecraft’s liquid engine at 16:51 IST for a duration of 817 seconds. The highly complex ‘lunar orbit insertion manoeuvre’ was performed from Chandrayaan-1 Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network at Bangalore.

If you had taken some time to read what was posted, you would see that the probe is still far from the Moon's surface, it has only just switched from an Earth orbit to a Moon orbit, too far for good photos.

4th there are no pictures of the moon that look like they were not taken from a telescope you can buy off ebay.
and NOW there are still no pictures of the lunar surface (yet)...and I am making a claim that what we do get to see is some s-h-i-t-t-y 150kb single picture of this MASSIVE EVENT!

2nd the earth pics were in B&W ..... WHAT THE FUDGE !!!??!!?!!!?
