Chandrayaan-2

Chandrayaan-2 is India's second lunar exploration mission after Chandrayaan-1. Developed by the Indian Space Research Organization (ISRO), the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). It includes a lunar orbiter, lander and rover. All these things are made in India; no foreign parts will be used in this mission.

Landing


If everything goes according to the ISRO’s plan then the lander and rover will land in a high plain between two craters,Manzinus C and Simpelius N, at latitude of about 70° south. If successful, Chandrayaan-2 will be the first mission to land a rover near the lunar South Pole.

The wheeled rover will move on the lunar surface and will perform on-site chemical analysis. The data can be relayed to Earth through the Chandrayaan-2 orbiter as well as lander.

Launching Schedule

Launch of Chandrayaan-2 is currently scheduled for 14 July 2019 at 21:21 UTC and a successful landing would make India the 4th country to soft-land on the Moon, earlier this is achieved only by the space agencies of US, USSR, and China.

Orbiter

The orbiter will orbit the Moon at an altitude of 100 km (62 mi). The approximate launch mass will be 2,379 kg.The Orbiter High Resolution Camera (OHRC) will conduct high-resolution observations of the landing site prior to separation of the lander from the orbiter. The orbiter's structure was manufactured by Hindustan Aeronautics Limited and delivered to ISRO Satellite Centre on 22 June 2015.



Lander (Vikram)

The mission's lander is called Vikram named after Vikram Sarabhai (1919-1971) who is widely regarded as the father of the Indian space programme.

The Vikram lander will detach from the orbiter and descend to a lunar orbit. Before landing it will check all its on-board systems.Unlike Chandrayaan-1's Moon Impact Probe, the Vikram lander will make a soft landing, deploy the rover, and perform some scientific activities for approximately 15 days. The approximate combined mass of the lander and rover is 1,471 kg.

Some associated technologies include a high resolution camera, navigation camera, hazard avoidance camera, an 800 N throttleable liquid main engine and altitude thrusters, altimeter, velocity meter, accelerometer, and the software needed to run these components.The lander's main engine has successfully undergone a high altitude test for a duration of 513 seconds. Engineering models of the lander began undergoing ground and aerial tests in late October 2016, in Challakere in the Chitradurga district of Karnataka. ISRO created roughly 10 craters on the surface to help assess the ability of the lander's sensors to select a landing site.

Rover (Pragyan)

The mission's rover is called Pragyan means wisdom.The rover's mass will be about 27 kg and will operate on solar power. The rover will move on 6 wheels traversing 500 meter distance on the lunar surface at the rate of 1 cm per second means very slow speed performing on-site chemical analysis and sending the data to the lander, which will relay it to the Earth station.

  • ·        Stereoscopic camera-based 3D vision using two NAVCAMs in front of rover will provide the ground team controlling the rovers a 3D view of the surrounding terrain and help in path planning by generating a digital elevation model of the terrain.


  • ·        Control and motor dynamics - The rover will have Rocker-bogie suspension system and six wheels, each driven by independent brushless DC electric motors.
