The Chandrayaan2 mission will take 48 days to reach the surface of the moon. The Chandrayaan2 spacecraft took off successful from the Satish Dhawan Space Centre located in Sriharikota. The moon mission launch was initially scheduled for July 15. The second launch which took place July 22, 2019 witnessed a successful lift-off and the Chandrayaan2 mission is on its way, 3, 84,000 kilometers to the Moon. Perigee is a point in the Moon’s orbit around the Earth that is closest to the Earth, and apogee is a point which is farthest from the Earth. Perigee and apogee refer to the distance from the Earth to the moon.
If the Chandrayaan2 mission is successful, it will be the second mission to land a rover near the lunar South Pole.
The first question strike is why Chandrayaan2 is taking 48 days when the space shuttle reaches in 3 days?
Cruising speed is its very simple answer.
Let’s understand it with a simple example that if your bike takes 48 minutes to reach any place and you want to reach in 3 minutes. So, you need a high powered bike. Same logic applies here. The faster you travel in space, the farther you can reach.
The cruising speed is an important factor in space missions. Considering flying to the moon requires an enormous amount of power escaping the gravity threshold.
Many factors administer how a spacecraft reaches the moon. The technology used in spacecraft, budget, or the urgency of the mission. Lower the number of days to reach the moon, the bigger the fuel burn and the bigger the cost.
The Chandrayaan-2 mission cost was Rs 978 crores which are around $141 million. This is $40 million cheaper than China’s moon exploration Chang’e 1 mission which cost $180 million back in 2007. The Chang’e 3 took four days, 12 hours, and 23 minutes to reach the lunar orbit.
For those on manned missions, the fastest one was the Apollo 11 mission which took 51 hours and 49 minutes more than two days to reach the lunar surface and back on July 19, 1969. And get this, the total cost of the mission then was $25 billion which is close to $150 billion in today’s currency. The three day period is the minimum amount of time any manned spacecraft has taken to reach the moon.
With India’s chandrayaan-2 homegrown technology will be deployed, scientists aim to expand India’s footprint in space, thrown light on an unexplored section of Moon the South Pole region, enhance knowledge about space, stimulate the advancement of technology and promote global alliances.
