Chandrayaan a pair of is associate Indian house analysis Organization (ISRO) mission comprising associate artificial satellite and a soft lander carrying a rover, scheduled to launch to the Moon in July 2019.
The primary objective of Chandrayaan 2 is to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface.
Scientific goals embrace studies of satellite topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.
Spacecraft and Subsystems
The Chandrayaan a pair of artificial satellite may be a box-shaped craft with associate orbital mass of 2379 kilogram and star arrays capable of generating a thousand W power.
The artificial satellite communicates with the Indian part Network and therefore the lander.
The artificial satellite can have a scientific payload comprising an obvious piece of ground mapping camera, a neutral mass spectrometer, a synthetic aperture radar, a near infrared spectrometer, a radio occultation experiment,
a soft X-ray spectrometer and solar X-ray monitor.
The lander, named Vikram, has a mass of 1471 kg (including the rover), and can generate 650 W of solar power.
The lander will communicate on to the Indian part Network, the orbiter, and the rover.
The lander will carry a camera, seismometer, thermal profiler, Langmuir probe, and a NASA-supplied laser retroreflector.
The rover, Pragyan (also Pragyaan), is a 6-wheeled vehicle with a mass of 27 kg that runs 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
Chandrayaan a pair of was launched on twenty two July 2019 at 9:13 UT (2:43 p.m.
Indian normal Time) from Satish Dhawan house Center on Sriharikota Island on associate ISRO fixed Satellite Launch Vehicle (GSLV) Mark III.
The lander-orbiter pair went into an initial elliptical (170 x 40400 km altitude) Earth parking orbit, followed by a trans-lunar injection on 14 August.
The combine entered satellite polar orbit on twenty August.
The lander and orbiter separated on September 2. The orbiter evolves into a 100 km altitude circular polar orbit and the Vikram lander maneuvered into a 30 x 100 km orbit with a plan to land on the surface 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). contact was lost during the descent at an altitude of about 2.1 km, the data are being analyzed.
The artificial satellite portion of the mission is planned to last one year.
The rover was to be deployed using a ramp shortly after landing. The lander and rover portions of the mission were planned for 14-15 days, one period of lunar daylight.
