Chandrayaan-2 is India’s Second mission to moon surface that started with a caution note and ended with limited success. The last update about the mission from ISRO is Chandrayaan 2 orbiter located Vikram landed, but there is no communication established. The mission traveled in the space for 48 days which is challenging, and ISRO ensured that craft would reach the south pole of the moon safely. This article will give you the Chandrayaan 2 journey from Earth to Moon Surface.
Chandrayaan 2 Mission Launch
ISRO planned Chandrayaan 2 mission launch on July 15th, 2019 with 20 hours of a countdown that began on July 14th. But it was called off due to some technical issue just one hour before the launch. Finally, the Chandrayaan 2 launch took place on July 22nd, 2019.
The weight of orbiter is 2,379 kilograms satellite, and the lander is 1,471 kilograms with rover inside of 27 kilograms. The mission has two parts the orbiter and lander-rover system with orbiter lifetime for one year. But ISRO announced saving the fuel during its travel the orbiter lifetime has extended up to seven years.
The Chandrayaan 2 mission lander-rover system is to position on Moon Surface and operate for 14 Earth days, which is one day on the Moon. The orbiter will study the lunar surface from an approximately 100-kilometer distance.
Chandrayaan 2 Journey Form Earth
The mission launched along with orbiter and lander-rover as one system. On September 2nd the lander-rover separated from the orbiter for its journey toward the moon. The landing attempted on September 7th, but the communication lost at the height of 2.1 Kilometer above the moon surface. As per the orbiter updates Vikram has the safe landing on the moon surface. However, only ISRO can identify the reasons for communication failure.
Apollo 11 has reached lunar orbit in just 51 hours 49 minutes launched by NASA as they have very powerful Saturn V rocket. The Chandrayaan 2 Indian Mission took 48 days because of not having a powerful rocket.
Causes of Mission Failure
After the launch of Chandrayaan 2 on July 22nd, it went through significant deviations in proposed orbits. On August 6th it went five orbit-raising which increased apogee up to 150,000 kilometers.
The Trans Lunar Insertion on August 14th which followed by Lunar Orbit Insertion maneuver on August 20th deviates the paths. Once in orbit around the Moon lower its orbit of five maneuvers. However, the lander has performed de-orbiting maneuvers on 3rd and 4th September after separation on September 2nd.
Landing on planet surface is a crucial part of any planetary mission. ISRO always announced that last landing part of Vikram is terrifying as it is all autonomy. The Lander has to travel 35 kilometers where the landing part takes 15 minutes which became as the “15 minutes of terror”.
Mission Failure Is Autonomous
Everything in this 15 minutes decent landing is autonomous, and we cannot do anything. Chandrayaan 2 type of missions are for the first time from ISRO, and a deviation in the trajectory is about 12 minutes into the downwards is visible. These are the word form chairman of ISRO after the landing failure. The journey of the India second Moon mission toward the moon surface.
It is due to a malfunction of the system in autonomous mode or may be due to the higher velocity than required at that height. There may also be reasons for a slight glitch in the engine functioning for the descent. Whatever the problems are, the Vikram did not have the safe landing on the Moon surface.
We can say that ISRO has to lead a fantastic moon journey, but failed in the landing the lander-rover on the surface. After understanding the cause of failure in the mission, ISRO can launch another mission in the near future. They already have an operational orbiter around the moon that helps to handle communication.
