Chandrayaan-2 Launch: How to Watch First Mission to the Moon's South Pole:

India's exploration mission to the moon is readying for launch. The Chandrayaan-2 mission, aiming to put robots at the lunar south pole for the first time, has suffered several delays leading up to lift-off. It was originally scheduled for July 14 but the Indian Space Research Organization (ISRO) postponed the departure less than an hour before launch due to a "technical snag."

The landmark mission is now set to depart from India's Satish Dhawan Space Centre in Sriharikota, north of Chennai, at 2:13 a.m. PT (5:13 a.m. ET), Monday July 22. [...] Chandrayaan-2 is carrying three lunar exploration robots that will be able to survey the moon from both the surface and the sky.

The payload of Chandrayaan-2 consists of a lunar orbiter, a lunar lander and a lunar rover and will be launched atop the ISRO-developed GSLV Mk-III rocket. That rocket is about half as powerful as the SpaceX Falcon 9 and will put Chandrayaan-2 into what's known as an "Earth parking orbit" before the module uses its own power to extend that orbit and eventually position itself for a lunar rendezvous.

Want to tune in to the historic mission? ISRO will handle livestreaming duties across its social media pages, which means you could tune in at the ISRO Twitter or follow along on the agency's Facebook page. The agency's YouTube channel is also covering the event.

The launch is also to be carried by the Indian public broadcaster Doordarshan's YouTube channel.

Chandrayaan-2 Latest Updates:

August 20, 2019

Lunar Orbit Insertion (LOI) maneuver was completed successfully today (August 20, 2019). The duration of maneuver was 1738 seconds beginning from 0902 hrs IST. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit. The orbit achieved is 114 km x 18072 km.

Following this, a series of orbit maneuvers will be performed on Chandrayaan-2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 100 km from the Moon's surface.

Subsequently, the lander will separate from the Orbiter and enters into a 100 km X 30 km orbit around the Moon. Then, it will perform a series of complex braking maneuvers to soft land in the South polar region of the Moon on September 7, 2019.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru. All the systems of Chandrayaan-2 are healthy.

The next Lunar bound orbit maneuver is scheduled tomorrow (August 21, 2019) between 1230-13:30 hrs IST.

August 21, 2019

Second Lunar bound orbit maneuver for Chandrayaan-2 spacecraft was performed successfully today (August 21, 2019) beginning at 1250 hrs IST as planned, using the onboard propulsion system. The duration of the maneuver was 1228 seconds. The orbit achieved is 118 km x 4412 km.

All spacecraft parameters are normal.

The next Lunar bound orbit maneuver is scheduled on August 28, 2019 between 0530 - 0630 hrs IST.

NASA (USA's National Aeronautics and Space Administration) reports that India's Vikram Lander has been Found:

The Chandrayaan 2 Vikram lander was targeted for a highland smooth plain about 600 kilometers from the south pole; unfortunately the Indian Space Research Organisation (ISRO) lost contact with their lander shortly before the scheduled touchdown (Sept. 7 in India, Sept. 6 in the United States).  Despite the loss, getting that close to the surface was an amazing achievement. The Lunar Reconnaissance Orbiter Camera team released the first mosaic (acquired Sept. 17) of the site on Sept. 26 and many people have downloaded the mosaic to search for signs of Vikram. Shanmuga Subramanian contacted the LRO project with a positive identification of debris. After receiving this tip, the LROC team confirmed the identification by comparing before and after images. When the images for the first mosaic were acquired the impact point was poorly illuminated and thus not easily identifiable. Two subsequent image sequences were acquired on Oct. 14 and 15, and Nov. 11. The LROC team scoured the surrounding area in these new mosaics and found the impact site (70.8810°S,  22.7840°E, 834 m elevation) and associated debris field. The November mosaic had the best pixel scale (0.7 meter) and lighting conditions (72° incidence angle).

The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic (1.3 meter pixels, 84° incidence angle). The November mosaic shows best the impact crater, ray and extensive debris field. The three largest pieces of debris are each about 2x2 pixels and cast a one pixel shadow.

See the NASA article for before/after pictures of the impact site.
