Both were to land near south pole of moon at far side. India had to be the first country to land on far side but Chandrayaan-2 delayed and Changé 4 did it first.

It really doesn't matter who landed first, but the thing matters is whose mission is more effective and who gains more

Chandrayaan is not scheduled to land on the far side. It is to land near the south pole

Far side in South pole.*

Far side of the tidally locked moon is not the same as South pole !! The south Pole is a more defined area there and we are going to land in a lighted area. One of the goal there is to search if water is there.

m also confused on this.....

Faar Side is NOT the same as South pole. Far side refersto the hemisphere that we do not regularly seedue to tidla locking. (A small portion is still seen due to libration) The South pole refers only to a small portion

You are making a statement like telling that the North pole of the Earth is the North Hemisphere !!
Chang'e did land near the South Pole in Von Karman Crater.. The goal of Vhandrayaan is to land as close as possible at the South Pole

Von Karman is itself a part Aitken basin considered to be in south pole.

Now, landing at "centre of south pole" is meaningless possession.

I don't think it is a pissing competition goal of Chandrayaan is relevant to our needs. Where on Earth was the goal to be the first ? What is indeed is the plan is to search for water as detected by Chandrayaan 1 mission.
Yes Von Karman crater is near but off the South Pole. Our goal is to try top select a site for its potential for water discovery. Different goals altogether.

Chandrayaan 2 postponed, they are stating again "next three months window".
Means, not before April, damn!

PRESS RELEASE ON CHANDRAYAAN-2

​

Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole. Further, the Rover will roll out for carrying out scientific experiments on the lunar surface. Instruments are also mounted on Lander and Orbiter for carrying out scientific experiments.

All the modules are getting ready for Chandrayaan-2 launch during the window of July 09, to July 16, 2019, with an expected Moon landing on September 06, 2019.

Chandrayaan - 2 Update

India aims for 1st landing near moon’s south pole
The moon’s south pole has never been explored from the ground, but India’s new Chandrayaan-2 mission will attempt a 1st-ever landing there, with a rover, this September.

So far, only three countries have successfully landed on the moon – the United States, the former Soviet Union and China – but that might change soon, if all goes according to plan. India is preparing to launch its second lunar mission this summer, and this time the goal is to actually land on the surface, near the moon’s south pole. If successful, India would become the fourth nation to land on the moon and the spacecraft, Chandrayaan-2, would be the first of any country to land in that region.

The Indian Space Research Organization (ISRO) announced the plans via Twitter on May 1, 2019. As of now, the spacecraft is scheduled to launch sometime between July 9 and July 16, 2019, from the ISRO launch facility on Sriharikota, an island off India’s southeastern coast.

This new mission is more ambitious than any previous Indian mission to the moon, and will include an orbiter, lander (Vikram) and rover (Pragyan). The landing itself won’t happen until September 6, 2019. As ISRO said in a statement:

All the modules are getting ready for Chandrayaan-2 launch during the window of July 9, to July 26, 2019, with an expected moon landing on September 6, 2019. The orbiter and lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-IIIlaunch vehicle. The rover is housed inside the lander.

After landing, the rover is designed to operate for at least 14 days on the surface and drive 1,300 feet (396 meters). That may not sound like a lot compared to NASA’s rovers on Mars, which have been able to drive for many years and travel at least several miles (as well as the Apollo rovers on the moon), but it will be a big accomplishment for ISRO if it succeeds, since it will be their first-ever moon rover. As K. Sivan, ISRO chairman, told The Times of India that, once Vikram lands on the lunar surface on September 6, the rover Pragyan will come out of the lander and roll out onto the lunar surface for about 300 to 400 meters (yards). It will spend 14 Earth-days on the moon, carrying out different scientific experiments. Altogether, he told The Times, there will be 13 payloads in the spacecraft: three payloads in rover Pragyan and the other 10 payloads in lander Vikram and orbiter.

The rover will use three scientific instruments including spectrometers and a camera to analyze the content of the lunar surface and send data and images back to Earth through the orbiter.

The launch of this mission had originally been planned for April 2018, but it was delayed to changes in the spacecraft design. The four-legged Vikram lander (a qualification model) had also suffered a fracture in one of its landing legs during testing earlier this year, contributing to the delay.

The landing near the moon’s south pole will be uncharted territory, where no other spacecraft has landed before. Previous orbiter missions, including India’s Chandrayaan-1, have found evidence for water ice in craters in this region, in locations where there is permanent shadow. With no atmosphere to speak of, temperatures remain exceedingly cold in those areas – about minus 250 degrees Fahrenheit (minus 157 degrees Celsius) – even though they can be boiling hot in sunlit regions. Water ice would be a valuable resource for future crewed missions back to the moon.

This will be India’s second lunar mission. The first, Chandrayaan-1, orbited the moon but did not land. It launched in October 2008 and operated for 312 days, until August 2009. By all measures it was a great success, with the orbiter circling the moon about 3,400 times.

On April 11, 2019, Israel’s Beresheet spacecraft attempted that country’s first landing on the moon – and the first landing of a commercial mission – but unfortunately it crashed after a problem with the main engine in the last few moments before landing. A little earlier, however, on January 3, 2019, China’s Chang’e-4 spacecraft did land successfully on the far side of the moon, another first in lunar exploration.

Hopefully this next mission from India will fare better, as a follow-on to the successful first Chandrayaan-1 mission. If so, this will be the first view from the ground near the moon’s south pole that we will have ever had from any spacecraft. Although studied from orbit, this part of the moon is still virtually unexplored, so it is an exciting opportunity to learn more about our nearest neighbor in space.

Bottom line: If all goes according to plan, India will become the first nation to land a spacecraft near the moon’s south in September of this year. Godspeed!

Chandrayaan to be launched on July 15

India's second lunar mission, Chandrayaan-II, will be launched on July 15 by>a GSLV-MkIII rocket from Satish Dhawan Space Centre (SDSC), Sriharikota Range. A combo of an orbiter, a lander named 'Vikram (after the late Dr Vikram Sarabhai), and a rover christened 'Pragyan', it will cruise through outer space for two months before entering into an orbit around the earth's nearest astral neighbour. The lander-rover will touch down on the Moon, close to the South Pole, in the first week of September to probe the lunar surface as well as carryout experiments. In all, 13 instruments (eight on the orbiter, three on the lander, and two on the rover) along with one from NASA (a laser retro-reflector array or LRA) will be carried onboard Chandrayaan-II, according to sources in ISRO.

Strange mass found under Moon's surface near ISRO's Chandrayaan-2 landing site

A mysterious mass of material has been spotted by researchers under the surface of the Moon. The mass is located under a crater in the Moon’s South Pole-Aitken basin, and researchers believe it could be metallic remnants from the asteroid that caused the crater in the first place.

According to researchers, the anomaly has a mass of 2.18 × 10^18 kilograms and is buried 300 km under the Moon's surface.
