New Delhi, July 22: The principle distinction between the 2 missions which each and every house fanatic is aware of is that Chandrayaan-1 didn’t contain touchdown on the floor of earth’s solely pure satellite tv for pc, whereas in Chandrayaan-2, a lander will make a gentle touchdown on the floor of the moon.

Listed here are another main variations:

The web weight of the spacecraft which was carried by PSLV (Polar Satellite tv for pc Launch Automobile) for Chandrayaan-1 on October 22, 2008, was 1380 kgs.

The Chandrayaan-2 spacecraft weighs roughly 3290 kilograms and it could launched by the Geosynchronous Satellite tv for pc Launch Automobile Mk-III (or GSLV Mk) rocket.

Chandrayaan-2: Changes made after July 15 launch abort

Chandrayaan-1 was carried a spread of scientific equipments, each Indian and worldwide, to the lunar orbit. The probe collected a variety of vital information over its mission. Throughout Chandrayaan-1, the Mini-Artificial Aperture Radar (Mini-SAR) discovered water-ice deposits in craters on the far aspect of the moon which was thought-about as a major discovering.

Chandrayaan-2 has three modules particularly Orbiter, Lander (Vikram) and Rover (Pragyan). The Chandrayaan-2 orbiter will circle the moon and supply details about its floor. Amongst many different research, the primary purpose is to check the moon’s mineral and chemical composition and its topology and seismology.

Chandrayaan-1 orbited the moon a distance of 100 kilometres from its floor, with a mission of chemical, mineralogical and photo-geologic mapping of the lunar satellite tv for pc.

The Chandrayaan-2 orbiter will circle the moon and supply details about its floor. The Lander will soft-land on the lunar floor and unload the Rover to check and take measurements from the floor. The lander and rover on Chandrayaan-2 will landing at a web site 600 kilometers from the lunar South pole.

Chandrayaan-1 carried 5 ISRO payloads and 6 payloads from different house businesses together with NASA, ESA, and the Bulgarian Aerospace Company.

In Chandrayaan-2, a complete of 13 payloads together with three from the Europe, two from the US and one Bulgaria, are distributed throughout the three modules the place the Orbiter and Vikram Lander are stacked upon one another whereas the Pragyan Rover is housed contained in the lander. A Laser Retroreflector Array (LRA) of US house company NASA is among the many payloads and is aimed toward understanding dynamics of Earth’s Moon system and deriving

Chandrayaan-2: There’s a lot at stake, postponed launch far better than failed launch

Chandarayan-1, concerned surveying the lunar floor to provide a whole map of its chemical traits and three-dimensional topography. Chandrayaan-1 was in operation for 312 days.

Chandrayaan-2, outfitted with a lander and rover, will observe the lunar floor and ship again information which will probably be helpful for evaluation of the lunar soil. The lander will carry devices like a seismometer and a thermal probe, and the rover will carry spectrometers to analyse the lunar soil. The lander and rover have nominal lifetimes of 1 lunar daytime (14 Earth days).
