This coming Friday will be an important day for India as it will launch its third mission to the moon. Mission will start at 14:35. Its goal is to achieve what the previous mission could not achieve, i.e. the goal of a gentle landing on the Moon.
A successful moon landing would make the country the fourth country in the world to land smoothly on the lunar surface, after the United States, Russia and China.
Mission to the Moon
First, the spacecraft will be launched into orbit around the Earth at an altitude of exactly 179 km. The spacecraft will slowly increase its orbit in a series of maneuvers to overcome Earth’s gravity and toward the Moon’s surface. when this happens, a second series of maneuvers will reduce the spacecraft’s orbit to a circular orbit of 100 x 100 km. The lander holding the rover inside will detach from the propulsion module and begin the engine descent.
How is it different from the previous mission?
S Somnath, president of ISRO, recently stated that the new mission changes are essentially “failure-based”. He said, “Instead of designing based on success in Chandrayaan-2, we are designing on failure in Chandrayaan-3 – looking at what could go wrong and how to deal with it.”
At the time of Chandrayaan-2, the rover and lander collided on the lunar surface, instead of making a gentle landing. The chairman explained that the main problem behind such a landing was that the five engines on the lander produced a little more thrust than expected.
