New Delhi, Sep 02: After a journey of around a month and a half, Chandrayaan-2 successfully separated the lunar lander, Vikram, from the Chandrayaan-2 orbiter. According to ISRO, the Vikram Lander successfully separated from Chandrayaan2 Orbiter at 1:15 pm.

Chandrayaan-2 readies for separation of lander Vikram from orbiter today

The Vikram Lander is currently located in an orbit of 119 km x 127 km. The Chandrayaan 2 Orbiter continues to orbit the moon in its existing orbit.

The separation will allow the lander to travel towards the lunar surface, leaving the Orbiter to continue to revolve around the moon.

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

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

"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.

Timeline of Chandrayaan-2's orbit manuevers

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.

The separation of the lander has been likened by the ISRO Chairman Dr Sivan to the bride leaving her parental home to reach her groom's residence. The location of the intended soft-landing is a plain lying in between two craters near the pole called Manzinus C and Simpelius N. The mission is totally indigenous, that has tided over several challenges on its way. Chandrayaan-2 is a technology demonstrator, and its findings are set to reveal many secrets of the moon under its fold.

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.

Following the landing, the rover 'Pragyan' will roll out from lander 'Vikram' between 5:30-6:30 am on September 7 and carry out experiments on the lunar surface for a period of one lunar day, which is equal to 14 earth days.

The mission life of the lander is also one lunar day, while the orbiter will continue its mission for a year. The orbiter carries eight scientific payloads for mapping the lunar surface and study the exosphere (outer atmosphere) of the Moon while the lander carries three scientific payloads to conduct surface and subsurface science experiments.

The rover carries two payloads to enhance the understanding of the lunar surface. India's second lunar expedition would shed light on a completely unexplored section of the Moon, its South Polar region. ISRO has said that the mission objective of Chandrayaan-2 is to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.
