ISRO chief announces what TSI''s Satish Chapparike had said a month ago
On the dawn of Wednesday, October 22, as the Sun rose from the Bay of Bengal near Sriharikota, India took a giant leap in the space. The first Moon Mission of country Chandrayaan-1 was successfully put into the earths orbit on that historic day. Before that when the countdown started at dawn, the ISRO scientific community was a little tense. They all eagerly awaited the outcome of the mission’s first stage. Those 20 minutes from the launch to fixing the lunar orbiter in the earth's orbit was the longest period of their lives. For more than 10 years, the thousand-member Chandrayaan-1 team had worked day and night for India's dream project, and for them that was the D-day.
Some of the world's top space scientists like Prof UR Rao, K Kasturirangan and Space Commission member Roddam Narasimaiah were there in that esteemed gathering. ISRO Chairman G Madhavan Nair, Project Director M Annadurai and the entire team of Chandrayaan-1 project team members were waiting inside a veritable 'pressure cooker'. Exactly at 06:22, PSLV was fired and carried the 1,380 kg lunar orbiter towards the earth's orbit. Exactly after 18.2 minutes the orbiter was successfully injected into the earth's orbit. Immediately, ISTRAC (ISRO telemetry, tracking and command network) at Peenya and Deep Space Network (DSN) at Byalalu started tracking the spacecraft with a few other tracking centres in the world. Once they started getting the signal from the spacecraft, there was sheer rejoicing all over. The first phase was successful.
Now the trickier and more challenging phase lies ahead. Later, through a series of highly complex manoeuvres, the desired trajectories will be achieved. After circling the earth in its Transfer Orbit, Chandrayaan-1 spacecraft will be taken into a more elliptical 'Extended Transfer Orbit' by repeatedly firing its Liquid Apogee Motor (LAM) in a pre-determined sequence. Subsequently, the LAM will be fired again to make the spacecraft travel to the vicinity of the moon. When it reaches the vicinity of the moon and passes at a few hundred kilometers from it, its LAM will be fired again, so that the spacecraft slows down sufficiently to enable the gravity of the moon to capture it into an elliptical orbit. Following this, the height of the spacecraft's orbit around the moon is reduced in several steps. After a careful and detailed observation of the orbit perturbations there, the orbital height of Chandrayaan-1 will be finally lowered to 100 km from the lunar surface. Especially this process is a fascinating one. It will be monitored by the Peenya and Byalalu ground stations with the help of other stations spread across the world. This entire process may take another 18 days. After that the Moon Impact Probe will be ejected from Chandrayaan-1 at the earliest opportunity to hit the lunar surface in a chosen area. Later, cameras and other scientific instruments will be turned on and tested. This leads to the operational phase of the mission, which lasts for about two years, during which Chandrayaan-1 explores the lunar surface with its array of instruments. The data will be sent to the ground stations. Within those two years, ISRO wants to explore the entire surface of the moon's dark, frozen side. With that will begin a new era in Indian and as well as world space science, and also the beginning of ‘Moon War’ between India and China.
