Bengaluru:

ISRO on Sunday said that it successfully performed the fifth and final lunar bound orbit manoeuvre for the Chandrayaan-2 spacecraft and was gearing up for the separation of the lander from the orbiter on September 2.

All spacecraft parameters are normal, the Bengaluru space agency said after Sunday's manoeuvre on the spacecraft, that is currently in the lunar orbit.

"The final and fifth Lunar bound orbit manoeuvre for Chandrayaan-2 spacecraft was performed successfully today (September 01, 2019) beginning at 1821 hrs IST as planned, using the onboard propulsion system. The duration of the manoeuvre was 52 seconds. The orbit achieved is 119 km x 127 km," the Indian Space Research Organisation said in an update.

It said the next operation is the separation of lander ''Vikram'' from Chandrayaan-2 Orbiter, which is scheduled on September 2, 2019, between 1245 hrs and 1345 hrs (IST).

Following this, there would be two deorbit manoeuvres of lander "Vikram" to prepare for its landing in the south polar region of the moon.

Vikram (with rover ''Pragyan'' housed inside) is expected to touch down on the lunar surface on September 7, between 1.30 AM and 2.30 am.

ISRO said that after the lander's separation on Monday, two deorbit manoeuvres are scheduled for September 3 (9:00-10:00) and September 4 (3:00-4:00) respectively, before the powered decent on September 7.

ISRO Chairman K Sivan has said the proposed soft-landing on the Moon would be a "terrifying" moment as it is something ISRO has not done before, whereas the Lunar Orbit Insertion manoeuvre was successfully carried out during the Chandrayaan-1 mission.

In a major milestone for India's second Moon mission, the Chandrayaan-2 spacecraft had successfully entered the lunar orbit on August 20 by performing the LOI maneuver.

Chandrayaan-2 satellite began its journey towards the moon,leaving the earth's orbit in the dark hours on August 14, after a crucial manoeuvre called Trans Lunar Insertion (TLI) carried out by ISRO to place the spacecraft on "Lunar Transfer Trajectory".

India's Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1 had successfully launched the 3,840-kg Chandrayaan-2 spacecraft into the earth's orbit on July 22.

The spacecraft's health is being continuously monitored from the Mission Operations Complex at ISRO Telemetry, Tracking and Command Network in Bengaluru with support from Indian Deep Space Network antennas at Bylalu, near Bengaluru, the space agency has said.
