Chandrayaan-2 to reach moon in a week

Chandrayaan-2 leaves earth's orbit 23 days after its launch moving towards moon

Chandrayaan-2 enters lunar trajectory for straight journey to Moon's orbit

The final orbit raising manoeuvre of Chandrayaan-2 spacecraft was successfully carried out earlier on Wednesday, according to a statement of the Indian Space Research Organisation (ISRO).

Those who are waiting endlessly for the lander, Vikram's soft landing on the Moon, the National Geographic is planning to stream a live show on September 7.

The Chandrayaan-2 was launched on July 22 and its orbit was progressively increased five times from July 23 to August 6. As per the plan, the module would be placed in an orbit which passes over the lunar poles at a distance of 100 kms from the moon's surface. Chandrayaan 2 will have to slow itself down just enough using its thrusters to fall into the moon's reach - gravitationally speaking.

Chandrayaan-2 is expected to reach the moon's orbit on August 20 and land on lunar surface on September 7.

On July 22, the Chandrayaan-2 was injected into an elliptical orbit of 170x45,475 km by India's heavy lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III) in a text book style.

The next maneuver would now be performed on August 20, when the spacecraft would approach the moon and its liquid engine will be fired again to insert the spacecraft into a lunar orbit.

The launch of Chandrayaan-2 on board GSLVMkIII-M1 at Satish Dhawan Space Centre in Nellore district, Tamil Nadu. "Thereafter, Lander 'Vikram", named after the father of Indian space programme Vikram Sarabhai, will separate from the orbiter and enter into a 100kmx30km orbit around Moon.

Chandrayaan-2 is loaded with 13 desi payloads that will do a detailed study of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical characteristics of top soil and composition of the tenuous lunar atmosphere for a new understanding of the origin and evolution of Moon.

The almost 150 million USA dollars worth of Moon Mission aims at gathering data on water, minerals and rock formations on the lunar surface. Now lunar orbit insertion of Chandrayaan will be done. If successful, Chandrayaan 2 will propel India to an elite list of four nations (including Russian Federation, the USA and China) that have pulled off a soft-landing on the moon. The mission life of the lander is also one lunar day, while the orbiter will continue its mission for a year.
