Chandrayaan 2's second attempt on-track to launch at 2:43pm

People gathered at a gallery to witness the first attempt at launching the Chandrayaan-2, in Sriharikota. The launch of the mission was called off due to some technical snags.PTI

  • Chandrayaan 2, India’s lunar mission to the Moon’s South Pole, is scheduled for its second launch at 2:43pm today.
  • The countdown began at 6:43pm yesterday and is progressing smoothly so far.
  • Chandrayaan 2’s voyage to the Moon is going to be India’s first attempt to soft land on the lunar surface.
The countdown for today’s $10 billion Chandrayaan-2 mission launch started at 6.43 pm yesterday and is going smoothly so far, according to the Indian Space Research Organisation (ISRO).

India is going to beat out China, Russia, and American if it manages to successfully land on the Moon’s South Pole — one of the most cratered areas on the room.

ISRO plans to attempt a south-landing and the chairman, K Sivan, has stated that those 15 minutes will be most ‘terrifying’ for the people back at the command module.

Surviving the landing

The aim is not only to be the first country in the world to land on the Moon’s South Pole to also work on the discovery of water initiated by Chandrayaan, India’s first mission to the moon.

ISRO hopes to determine how much water is on the Moon, where its located and hopefully be able to determine future spots for exploration.

Aside from water, the tech instruments abroad the lander, rover and orbiter — the three components of Chandrayaan 2 — will also try and determine the quantities and locations of other primary elements on the moon.

The world is hoping for some exotic discoveries considering that the craters have sheltered these elements for millions of years in an environment that dips down to below 270 degrees Celsius.

The last time

The GSLV-Mk III rocket with Chandrayaan-2 spacecraft was originally scheduled for flight at 2.51 am on July 15. However, the flight was postponed after a ‘ technical snag’ was detected an hour prior to the rocket lift-off.

There was reportedly pressure loss in the one of the fuel chambers of the launch vehicle.

ISRO later rectified the fault in its 44-metre Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III). Weighing about 640-tonne, the GSLV-Mk III rocket is nicknamed 'Bahubali' after the hero of a successful Bollywood film of the same name.

The rocket will carry the 3.8-tonne Chandrayaan-2 spacecraft.

Not Bahubali’s first stint in space

About 16 minutes into its flight, the GSLV-Mk III rocket is expected to sling the Chandrayaan-2 into its 170 x 40400-km orbit.

ISRO has sent up three GSLV-Mk III rockets so far. The first carried Crew Module Atmospheric Re-entry Experiment in December 2014. The second and third GSLV-Mk III carried communication satellites GSAT-19 and GSAT-29 in February 2017 and November 2018 respectively.

GSLV-Mk III will also be used for India's manned space mission in 2022.
