What is Chandrayan 2?

Chandrayaan 2


What is Chandrayan 2: It is an Indian Space Research Organization (ISRO) mission comprising an orbiter and a soft lander carrying a rover, scheduled to launch to the Moon on July 2019. The primary purpose of Chandrayaan 2 is to confirm the ability to soft-land on the lunar exterior and perform a robotic rover on the surface. Scientific goals include investigations of lunar topography, mineralogy, elemental wealth, the lunar exosphere, and trademarks of hydroxyl and lake ice.

Spacecraft and Subsystems

The orbiter is a box-made craft with an orbital volume of 2379 kg and solar designs capable of generating 1000 W power. The orbiter interacts with the Indian Deep Space Network and the lander. The orbiter will have a precise payload containing a visible terrain mapping camera, a neutral mass spectrometer, a plastic aperture radar, a near-infrared spectrometer, a radio occultation analysis, a soft X-ray spectrometer, and solar X-ray monitor.

The lander, named Vikram, has a volume of 1471 kg (including the rover) and can produce 650 W of solar power. The lander can talk directly to the Indian Deep Space Network, the orbiter, and that rover. The lander will bring a camera, seismometer, thermal profiler, Langmuir probe, and a NASA-supplied laser retroreflector.

The rover, Pragyan (also Pragyaan), is a 6-wheeled transport with a mass of 27 kg that appears on 50 W of solar power and can travel up to 500 m at a speed of 1 cm per second. The rover communicates directly with the lander. the rover will hold cameras, alpha-proton X-ray spectrometer, and a laser-induced ablation spectroscopy experiment.

Mission Profile

Our Chandrayaan was launched on 22 July 2019 at 9:13 UT (2:43 p.m. Indian Standard Time) of Satish Dhawan Space Center on Sriharikota Island on an ISRO Geosynchronous Satellite Launch Vehicle (GSLV) Mark III. The lander-orbiter both went into an initial elliptical (170 x 40400 km altitude) Earth parking orbit, accompanied by a trans-lunar injection on 14 August. The couple entered lunar polar orbit on 20 August. The lander and orbiter departed on September 2. The orbiter results into a 100 km altitude circular polar area and the Vikram lander moved into a 30 x 100 km orbit with a plan to land on the outside in the high latitude areas near the south pole, between two craters, Manzinus C and Simpelius N, on 7 September between about 1:30 and 2:30 a.m. Indian local time (Sept. 6, 20:00-21:00 UT). connection was lost during the descent at an altitude of about 2.1 km, the data are being analyzed. The orbiter portion of the mission is planned to last 1 year. The rover was to be deployed using a ramp shortly after landing. The lander and rover portions of the charge were prepared for 14-15 days, one period of lunar daylight.
