Chennai The countdown for Chandrayaan-2 mission launch is progressing smoothly. Countdown for Rs 978 crore Chandrayan-2 Mission started at 6.43 p.m. on Sunday.

The rocket and spacecraft’s systems will undergo checks and fueling during the countdown.

The rocket is scheduled to lift off at 2.43 p.m. later.

According to ISRO, fueling of the second stage/engine with unsymmetrical dimethylhydrazine (UDMH) and nitrogen tetroxide (N2O4) has been completed.

The average distance of Moon from Earth is 3, 84, 000 km, Vikram lander will land on Moon on the 48th day of the mission, which begins today.

ISRO called off Chandrayaan-2 launch, due to technical snag

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

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

About 16-minutes into its flight, the Rs 375-crore GSLV-Mk III rocket is expected to sling the Rs 603-crore Chandrayaan-2 into its 170×39, 120-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.
