  • President Ram Nath Kovind has reached Sriharikota
  • The 20-hour countdown began on Sunday morning at 6:51 am
  • Chandrayaan-2 mission has been described as one of the most complex missions

Chandrayaan-2, India’s Moon mission to the unexplored south polar region of the Moon, will be launched a few hours from now from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. President Ram Nath Kovind has reached Sriharikota to witness the launch of Chandrayaan-2. The 20-hour countdown began on Sunday morning at 6:51 am for the launch of Chandrayaan-2.

Chandrayaan-2 mission has been described as one of the most complex ever undertaken by the Indian Space Research Organisation (Isro). “Chandrayaan 2 is going to be the most complex mission that Isro has undertaken so far. Scientifically, it is a follow on mission to confirm data from Chandrayaan 1. It is going to be a big motivator for the young scientific groups,” former Isro chief G Madhavan Nair said.

A number of public figures and personalities have congratulated praised the women scientists who have worked on the Chandrayaan-2 project.

LISTED ARE 11 POINTS ON CHANDRAYAAN-2 MISSION LAUNCH

  • Chandrayaan-2 mission will be launched at 2:51 am from Satish Dhawan Space Centre in Sriharikota. The Isro will begin the live streaming of the Chandrayaan-2 launch at 2:30 am on various platforms such as Facebook, Twitter, YouTube etc.
  • Isro’s most powerful launcher — 640-tonne GSLV MK-III or “Bahubali” will carry Chandryaan-2 to its designated orbit. The three-stage vehicle is capable of launching 4-tonne class of satellites to the Geosynchronous Transfer Orbit (GTO).
  • 973.7 seconds after lift-off from Sriharikota, Chandryaan-2, carrying lander-Vikram and rover-Pragyaan, will separate from the rocket and head to the south pole of the Moon.
  • The journey is expected to take nearly two months (54 days). The distance between the earth and the moon is about 3.844 lakh km. The lander-orbiter separation will take place on the 50th day.
  • The Lander Vikram is expected to make a soft landing on the Moon and then Pragyaan will roll out to carry out the experiments. Did you know Chandrayaan 2’s lander Vikram is named after Dr Vikram A Sarabhai, Father of the Indian Space Programme.
  • The landing of the lander Vikram is planned between two craters on the Moon.
  • The rover Pragyaan, meaning wisdom in Sanskrit, can travel up to 0.5 km at a speed of one centimetre per second and can communicate with the lander. The rover leverages solar energy for its functioning.
  • Actors Sonakshi Sinha and Akshay Kumar took to Twitter to praise women scientists for leading the Chandrayaan-2 mission. 
  • Important components of the modules of Chandrayaan-2 were manufactured by a Union government-run centre in Bhubaneswar. Seven specific assemblies for navigation and inertial momentum of the orbiter and the limbs of the rover ‘Pragyaan’ have also been manufactured by the centre. It had started manufacturing the Chandrayaan-2’s parts in March 2017.
  • In a statement, Isro said that through the launch of Chandrayaan-2 mission, the space agency aims to improve the understanding of the Moon, which, it said, could lead to discoveries that will benefit India and humanity as a whole. 
  • Meanwhile, students and teachers at a government school in Visakhapatnam’s Malkapuram area held special prayers on Sunday for the success of Chandrayaan-2 launch and the mission.
