Vikram lander has been located by the orbiter of Chandrayaan-2, but no communication with it yet. All possible efforts are being made to establish communication with lander

September 4, 2019

The second de-orbiting maneuver for Chandrayaan-2 spacecraft was performed successfully today (September 04, 2019) beginning at 0342 hrs IST as planned, using the onboard propulsion system. The duration of the maneuver was 9 seconds.

The orbit of Vikram Lander is 35 km x 101 km. Chandrayaan-2 Orbiter continues to orbit the Moon in an orbit of 96 km x 125 km and both the Orbiter and Lander are healthy.

With this maneuver the required orbit for the Vikram Lander to commence it descent towards the surface of the Moon is achieved. The Lander is scheduled to powered descent between 0100 - 0200 hrs IST on September 07, 2019, which is then followed by touch down of Lander between 0130 - 0230 hrs IST

Chandrayaan-2 mission was a highly complex mission, which represented a significant technological leap compared to the previous missions of ISRO, which brought together an Orbiter, Lander and Rover to explore the unexplored south pole of the Moon. Since the launch of Chandrayaan-2 on July 22, 2019, not only India but the whole world watched its progress from one phase to the next with great expectations and excitement. This was a unique mission which aimed at studying not just one area of the Moon but all the areas combining the exosphere, the surface as well as the sub-surface of the moon in a single mission. The Orbiter has already been placed in its intended orbit around the Moon and shall enrich our understanding of the moon’s evolution and mapping of the minerals and water molecules in the Polar Regions, using its eight state-of-the-art scientific instruments. The Orbiter camera is the highest resolution camera (0.3m) in any lunar mission so far and shall provide high resolution images which will be immensely useful to the global scientific community. The precise launch and mission management has ensured a long life of almost 7 years instead of the planned one year. The Vikram Lander followed the planned descent trajectory from its orbit of 35 km to just below 2 km above the surface. All the systems and sensors of the Lander functioned excellently until this point and proved many new technologies such as variable thrust propulsion technology used in the Lander. The success criteria was defined for each and every phase of the mission and till date 90 to 95% of the mission objectives have been accomplished and will continue contribute to Lunar science , notwithstanding the loss of communication with the Lander.

Lunar surface imaged by Terrain Mapping Camera 2 (TMC-2) on 23rd August 2019 at an altitude of ~4375 km showing impact craters such as Jackson, Mitra, Mach and Korolev.

Jackson is an impact crater located in the northern hemisphere of the far side of the Moon.  It is a 71 km dia crater at 22.4°N and 163.1°W (shown in the inset).   The interesting feature at the western outer rim of Mach crater is another impact crater, Mitra (92 km dia).  It is named after Prof. Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan recipient known for his pioneering work in the field of ionosphere and Radiophysics. The Korolev crater seen in the image is a 437 km crater which has several small craters of varying sizes.
