Quote
The ISRO chief while delivering a speech at the seventh annual convocation of Vels University on Wednesday said that tests were underway for a controlled landing of the spacecraft on the surface of the moon.

"ISRO will develop an engine that will help in the controlled landing on the moon. The mission is currently planned for the first quarter of 2018," he said, adding that scientists had developed an artificial crater to simulate the surface of lunar conditions for the landing experiments.

He further revealed that a series of ground tests is also in progress at the ISRO facility in Mahendragiri, Tirunelveli district, and in Challakere, in Chitradurga district near Bengaluru. "The satellite is also getting ready," he added.

Chandrayaan 2, which consists of an Orbiter, Lander and Rover configuration, is an advanced version of the previous Chandrayaan-1 mission.

It is planned to be launched as a composite stack into the Earth Parking Orbit (EPO) of 170 X 18,500 km by GSLV-Mk II, as per the Indian Space Research Organisation.

Some post on Quora.com gives the landing coordinates as the following:

Main site: 87.2 deg S, 68 deg E
Backup site: 88.5 deg S, 297 deg E

Where exactly are these locations? What are the major features over there?

Sorry to disappoint you but those are very old locations from a site study done in 2010 when Chandrayaan 2 was still a joint Russian-Indian mission.  The most recent report on the site selection was this one in 2015:

http://www.hou.usra.edu/meetings/lpsc2015/pdf/1351.pdf

A 2016 presentation in Turkey was halted when the conference was cancelled, so there is no more recent update, as far as I know.

Ah, thanks very much for that - I see that the proposed Cabeus Crater landing site is ~150km from the Shackleton Crater landing site where Bezos would like to set up a moonbase.

I guess ISRO has picked the same general vicinity because it means longer solar illumination that won't necessitate the use of nuclear RTGs to keep the rover from freezing at night? And of course it also has the permanently shadowed regions (cold traps) where water ice might still persist.

So is this region going to be the Lunar Mesopotamia, most friendly to potential colonization efforts?
(and thus eventually the most contested, down the road)

Yes, it's LADEE.  This link to Youtube (you don't need to watch the video) shows the name LADEE in the caption under the image:



In fact the 'video' is a single still shot of LADEE with a voice-over describing Chandrayaan.  Weird!  As for the image showing up in AW&ST, their quality control isn't what it was.

ISRO chairman A. S. Kiran Kumar confirms that ISRO is to launch Chandrayaan-2 mission in early 2018.

Quote
Indian Space Research Organisation (Isro) will launch its Chandrayaan-2 mission, an advanced version of its previous 2018 mission with the objective of deeper lunar surface probe, and another mission by Team Indus, a group of space enthusiasts who want to unfurl the tricolour on the moon's surface as part of a global lunar competition.

Quote
While Team Indus is using the service of PSLV to take its 600-kg baby spacecraft to the lunar orbit, Isro will use its heavylift rocket GSLV Mk II for the mission. Dr K Sivan, director of Thiruvananthapuram-based Vikram Sarabhai Space Centre, told TOI, "Unlike the 2008 Chandrayaan-1 mission when PSLV rocket was used for carrying the spacecraft, this time Isro is planning to take a heavier payload (combined launch mass: 3,250 kg) comprising orbiter, lander and rover to the moon. Therefore, GSLV Mk II is the preferred choice."

Highlights
    * Isro will use GSLV Mk II for Chandrayaan-2 as payload is heavier this time (combined launch mass 3,250 kg).
    * Orbiter will be deployed at an altitude of 100km above lunar surface.
    * Scientific payloads on board orbiter, lander and rover will perform mineralogical and elemental studies of lunar surface.

I wonder if the Indians will do as the Chinese did with Chang'E 3 and broadcast live pictures from the lander as it descends to the lunar surface ....... ?

Were they transmitted live?  I thought they were recorded and transmitted later from the surface.  I could be wrong.
