ISRO a step closer to creating history after Lander Vikram separates itself from Chandrayan 2 successfully
“The Vikram Lander successfully detached itself from Chandrayaan-2 Orbiter at 13:15 IST today. Currently located in an orbit of 119 km x 127 km Vikram lander is all set to create history. According to ISRO said in a statement, The Chandrayaan-2 Orbiter will continue to orbit the Moon in its existing orbit, The next maneuver is scheduled for Tuesday between a timespan window of 8:45 pm and 9:45 pm. This 'Vikram' from Chandrayaan-2 orbiter separation was scheduled between 12:45 pm and 01:45 pm (IST). Following this, there would be two deorbit maneuvers of lander 'Vikram' to prepare for its landing in the south polar region of the moon.
This Chandrayaan-2 satellite had begun its journey towards the moon on August 14this year, leaving the earth's orbit in the dark hours, through after a crucial maneuver called Trans Lunar Insertion (TLI) which was 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.
“Monitoring the health of the orbiter and lander is being undertaken at the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru. All the systems of Chandrayaan-2 Orbiter and Lander are healthy, according to ISRO personnel.
Regarding the upcoming launch, following the landing, the rover 'Pragyan' will roll out from lander 'Vikram' between as early as 5:30-6:30 am on September 7 and will carry out experiments on the lunar surface for a period of one lunar day, which will prolong for 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 as many as eight scientific payloads for mapping the lunar surface and designed to study the exosphere, which is also the last layer of the atmosphere, exosphere of the moon will be studied, while the lander will carry three scientific payloads to conduct surface and subsurface further scheduled science experiments. The rover also carries two payloads that enhance the understanding of the lunar surface.
India's second lunar expedition would shed light on a completely unexplored section of the Moon, it's South Polar region, which is as exclusive as it gets as of now. ISRO has earlier specified 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.On the science front, this very mission seeks to further expand the knowledge about the moon by carrying out a thorough and minute study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics, and atmosphere, leading to a better understanding of the origin and evolution of the moon, the Indian based organization had emphasized.
