Chandrayaan-2

  • The Indian Space Research Organisation (ISRO) said it conducted a dry run of all operations related to the Chandrayaan-2 lunar mission, scheduled for launch on 15 July, 2019.
  • The full-dress rehearsal was conducted at ISRO’s launch centre at Sriharikota in Andhra Pradesh, a week before the launch of India’s second lunar mission in 11 years.
  • Chandrayaan-2 is designed to place a lander and a robotic rover near the lunar south pole, a site that has not been explored by any country yet.
  • Only Russia, the U.S. and China have soft-landed on moon so far.
  • The spacecraft is due to land on the moon on September 6.
  • Soon after the launch, the spacecraft — the orbiter carrying the lander-rover combine — must complete five orbit-raising manoeuvres around the earth.
  • It will leave the planet’s atmosphere 16 days later, around early August, 2019.
  • The journey to the moon, some 3.84 lakh kilometres away from the earth, will take five days.
  • However, once it goes near the moon, the spacecraft will do another round of manoeuvres and orbit the moon for 27 days before the lander separates to touch down on the lunar surface.
  • ISRO is using its heavy lift launcher, the GSLV-MkIII, to launch the Rs. 978-crore Chandrayaan-2.
  • The spacecraft weighs 3,840 kg.
  • The previous orbiter-only Chandrayaan-1  mission was launched on the PSLV in October 2008.
