Its countdown has started and it will be launched at 2.43 minutes this afternoon. Earlier this launch was to happen on July 15, 2019 but due to technical failure, it was postponed in the last minute.

The Second moon mission of the Indian Space Research Organization (ISRO) will be launched from Chandrayaan-2 today ie, July 22 at 2.43 pm, the country’s most powerful rocket GSLV-MK3.

  • After this, a 48-day journey of Chandrayaan-2 will begin to reach the Moon’s South Pole.
  • After about 16.23 minutes, Chandrayaan-2 will be separated from the GSLV-MK3 rocket at an altitude of about 182 km from Earth and will rotate in the orbit of the Earth.

Chandrayaan-2 Mission

Chandrayaan-2 is India’s second lunar exploration mission after Chandrayaan-1, developed by the Indian Space Research Organisation.

Objectives

  • Quantify the water available on the moon’s surface.
  • Map its topography, to explore chemicals and minerals such as magnesium, iron, and Helium.
  • Study topmost part of the lunar atmosphere.

Significance

  • Global Power: If successful, India will be the fourth country (After Russia, China, and the USA) to land a rover on the moon.
    • India will be the first country to land on the southern pole of the moon.
    • This would give ISRO opportunity to name that site on the moon.
  • Indigenous mission: 13 instruments from India, one instrument from US space agency, NASA.
  • Future Space Exploration: mission will also expand the country’s footprint in space as moon is the perfect test-bed for proving technologies required for future space exploration.

Complexities involved in a moon landing

  • Trajectory accuracy: Ensuring trajectory accuracy while navigating 3.844 lakh km has its own challenges.
  • Communication hurdle: Owing to the large distance from Earth, radio signals, which need to be picked up, would be weak.
  • Lunar dust: Firing engines close to the lunar surface results in the backward flow of gases and dust, causing hindrance to deployment mechanism and damaging sensors.
  • Extreme temperatures: A lunar day or night lasts 14 earth days, resulting in extreme surface temperature.
  • Trans-lunar injection, capture: Series of engine burns to get close to the moon, intersection of probe and moon must be predicted in advance with accuracy.
  • Orbiting: The lumpy lunar gravity influences the orbit of the spacecraft.

How Many Payload It Will Carry ?

  • While the orbiter will carry 8 payloads, the Vikram will have four and the Pragyan will have two payloads.

Chandrayaan-2 weighing 3,877 kg

  • Chandrayaan-2 will be launched from India’s most powerful GSLV Mark-III rocket.
  • This rocket will have three modules orbiter, lander (Vikram) and rover (pragyan).
  • Under this mission, ISRO will land the lander at the southern pole of the Moon.
  • This time, Chandrayaan-2 will weigh 3,877 kg.
  • It is about three times more than the Chandrayaan-1 mission (1380 kg).
  • The speed of the rover inside the lender will be 1 cm per second.

What is Chandrayaan-2 mission? How different is it from Chandrayaan-1?

  • On the new date fixed, Chandrayaan-2 will be launched from Satish Dhawan Center, Sriharikota, from India’s most powerful GSLV Mark-III rocket.
  • Chandrayaan-2 is actually a new version of Chandrayaan-1 mission.
  • It includes orbiter, lander (Vikram) and rover (pragyan). Chandrayaan-1 had only orbiter, which roamed in the orbit of the moon.
  • India will launch lander on moon surface for the first time through Chandrayaan-2.
  • This landing will be on the southern pole of the moon.
  • With this, India will become the first country to land on the moon’s southern pole.

What will the orbiter, lander and rover work?

  • After reaching the orbit of the orbit, the orbiter will work for one year.
  • Its main purpose is to communicate between Earth and Lander.
  • The orbiter will map the surface of the moon so that the existence and development of the moon can be traced.
  • At the same time, Lander and Rover will work on the moon (equivalent to 14 days of Earth).
  • Lander will check whether earthquakes occur on the moon or not.
  • Whereas, the rover will detect the presence of mineral elements on the surface of the moon.

Chandrayaan 2 Lander Name ?

  • The Name Of Chandrayaan Lander Is Vikram

Chandrayaan 2 Rover Name ?

  • The Name Of Chandrayaan Rover is Pragyaan 

 

What Are The Main Differences Between Chandrayaan 1 And Chandrayaan 2 ?

Chandrayaan 1 Chandrayaan 2
Chandrayaan 1 Was The First Mission To Moon It is 2nd Mission to Moon From India
It Was Launched In 2008 It is Launched In 2019
Launched By PSLV – C11 Launched By GSLV MK III
It Was Opetational For 312 Days
  • The mission life of Orbiter will be 365 days
  • whereas the mission life of Vikram lander and Pragyaan Rover will be one Lunar day which is equal to fourteen earth days.
Weight Was 1380 Kgs The lift-off mass of Chandrayaan-2 is said to be 3,850 kg
  • The Chandrayaan-1 discovered traces of water on the moon-a path-breaking discovery in the world of space science.
  • Chandrayaan-1 also discovered water ice in the North polar region of the Moon.
  • It also detected Magnesium, Aluminium and Silicon on the lunar surface.
  • Global imaging of the moon is another achievement of this mission.
  • .Chandrayaan-2 aims to widen the scientific objectives of Chandrayaan-1 by way of soft landing on the Moon and deploying a rover to study the lunar surface.
  • It has always been important for space scientists around the world to study Moon as understanding the way in which moon was formed and evolved (gradually changed over a period of time) helps us to understand the history of the solar system as well as of earth.
  • There were eleven scientific instruments onboard Chandrayaan-1 spacecraft.
  • Five of them were Indian and other six were from ESA (3), NASA (2) and Bulgarian Academy of Sciences (1) selected through ISRO Announcement of Opportunity (AO).
  • Two of the ESA instruments had Indian collaboration.
  • The orbiter will carry 8 scientific payloads for mapping of the lunar surface and outer atmosphere.
  • The Lander will carry three scientific payloads while the Rover will carry two scientific payloads to conduct experiments on the moon’s surface.
  • Moreover, this time, a passive experiment from NASA will also be carried onboard Chandrayaan-2
