Chandrayaan-2 Ready for moonwalk – The Economic Times


India’s second mission to the moon, Chandrayaan-2, would be launched on July 15, Isro announced on Wednesday. The landing on the moon near the South Pole, an uncharted territory, would be on Sept 6 or 7. This is the Indian space agency’s most complex mission so far


Women on Top Mission:


Director—Ritu Karidhal
Project Director—Vanitha M

Mission Cost: Rs 603 crore

  • Orbiter, Lander and Rover and 14 instruments. The cost includes fees for navigation services paid to foreign space agencies
  • Location chosen is on the polar region of the moon; less craters, has 18 degree slope and more chances of water
  • Day is chosen because it is the start of the lunar day (14 earth days)

Mission objectives:

  • Quantify the water available on the moon’s surface
  • Explore minerals such as magnesium, ion and Helium
  • Map its topography, explore minerals and chemicals on its surface Study top most part of the lunar atmosphere
  • If successful, India will be the fourth country to land a rover on the moon.
  • Indigenous mission, 13 instruments from India, one instrument from Nasa

Launcher:

  • GSLV Mk-3, India’s heaviest rocket. 43 metres long, it has a lift-off mass of 640 tonnes and costs Rs 375 crore
  • Total weight is at 3.8 tonnes -Integrated module with Orbiter, lander and rover including 14 instruments

1,500 INDIAN COMPANIES CONTRIBUTED TO GSLV MK-3, PLUS


15 ACADEMIC INSTITUTIONS INCLUDING INDIAN INSTITUTE OF SCIENCE & IITS ISRO WILL REPLICATE THE SUCCESS OF CHANDRAYAAN-1 BY USING THE EARTH’S GRAVITY TO SLING THE SPACECRAFT TO THE MOON

Rover (Pragyaan)

27 kg No of instruments 2

MISSION LIFE IS ONE LUNAR DAY

  • Payload includes Laser-Induced Breakdown Spectroscope that would drill into the lunar surface, collect samples to understand chemical composition and mineralogical composition on lunar surface
  • Alpha Particle X-Ray Spectrometer will determine the elemental composition of the lunar rocks and soil

Lander (Vikram): 1,371 kg

Number of instruments: 4 (including rover); it will touch down on the moon surface at 2 metre per second

MISSION LIFE IS ONE LUNAR DAY Payload includes Instrument for Lunar Seismic Activity to measure lunar earthquake around the landing site and structure of lunar crust & mantle.
