Announcing the success of yet another key manoeuvre in the ambitious Rs 978-crore Chandrayaan-2 mission, the Indian Space Research Organisation(ISRO) said the separation of lander ‘Vikram’, which is set for soft landing on September 7 on the lunar surface along with rover ‘Pragyan’, was carried out at 1.15 pm. The space agency also said all systems of Chandrayaan-2’s orbiter and the lander were healthy.
ISRO Chairman K Sivan last month said that the separation of the lander from the orbiter will be akin to a bride leaving her parental home. The separation was carried out successfully, an ISRO official said.
The milestone event came 42 days after the mission was launched onboard India’s most powerful rocket GSLV-MkIII-M1 from the spacesport of Sriharikota on July 22 and after a series of earth and lunar orbit manoeuvres, that took the spacecraft closer to the moon gradually.
The fifth and final lunar orbit manoeuvre was carried out on Sunday.
In a statement, the ISRO on Monday said the lander, after the separation, was located in an orbit of 119 km perigee (closest point from moon) and 127 km apogee of the moon’s orbit.
The Chandrayaan-2 Orbiter, which has a mission life of one year, continues to go around the Moon in its existing orbit.
The ISRO said the health of the Orbiter and Lander was being monitored from the Mission Operations Complex at ISRO Telemetry, Tracking and Command Network (ISTRAC) here with support from Indian Deep Space Network (IDSN) antennas at nearby Bylalu.
After the separation, two deorbit manoeuvres of the lander to bring it further down will be carried out on September 3 and September 4 to prepare for its landing in the south polar region of the moon, where no country has gone so far.
The first of the manoeuvres was scheduled on Tuesday between 8.45 am and 9.45 am IST, the ISRO said.
