K Sivan said that while they were trying to establish contact with 'Vikram', the orbiter's life had increased to 7.5 years due to the optimal mission operation though its designed life was one year.
Sivan said that ISRO is focusing on another moon mission by 2020 for which discussion is on without nothing being finalised.
Lander Vikram, with rover Pragyan, housed inside it, lost communication with the ground station on September 7 during its final descent, just 2.1 kms above the lunar surface.
A single-engine would have obviated the complexities of managing the four throttleable engines working in union, a former ISRO official said.
These images were taken on September 17 when the LRO passed over the site near the moon’s south pole at an altitude of 50 km.
LRO project scientist at NASA's Goddard Space Flight Center, Noah Petro, said on Wednesday that they were analysing the images taken on Tuesday but the current illumination conditions are 'harsh'.
While there have been suppositions that the lander would have captured essential data, there is no way to ascertain this unless contact is made.
The lander, in its ‘last moment’ of impacting the lunar surface on September 7 has helped expose subsurface material to the scrutiny of a powerful payload onboard Chandrayaan-2 orbiter.
Brad Pitt was at NASA's Washington headquarters and he called the International Space Station to converse with astronaut Nick Hague.
The 14 Earth days-window or one lunar day, which is the mission life of the lander, ends on September 20-21 by when total darkness sets in.
As ISRO celebrates its 50th year since establishment, the float also features their achievements.
However, it remains to be seen how the systems on the lander survive through the lunar night which see temperatures dip to as low as -150 degrees Celsius.
Terming Chandrayaan-2 a “wonderful mission”, Sharma felt that despite the issues with the Vikram lander, the country can be proud of its achievement through Chandrayaan-2.
Lander Vikram, with rover Pragyan, housed inside it, lost communication with ground-station early on September seven during its final descent, just 2.1 kms above the lunar surface.
