ISRO Latest Mission Chandrayaan - 2 Quick Look (Indian Goverment Space Agency Launch Delayed to 22 July)

Indian Government Space Agency is planning to launch its mission to the Moon on 22nd July. Chandrayaan 2 is an Indian lunar mission which will boldly go where no country has ever gone before.ISRO will land the Lander on the Moon's south polar region, to explore the darker side of the Moon. ISRO Has been hit agency in exploration, in 2013 we(I'm an Indian BTW) launched our first mission to Mars and succeeded on the first-ever try. No other country has ever done what we did in 2013; the budget for the whole project was $73 million, which is lower than the budget of the blockbuster movie Interstellar. We create the best instruments to improve the space travel and exploration, out brightest scientists, work hard to make Indian space agency best in the world. We will discuss the latest mission of ISRO - Chandrayaan 2.

Why are we going to the Moon?

Our natural satellite Moon is the closest cosmic body on which space discovery can be attempted and documented.
This mission will help us to know and demonstrate the technologies that are used for the deep-space missions.Chandrayaan-2 will boost our knowledge about outer space and increase our understanding of Space. The mission will prove that India is becoming a stronger democracy, which will promote a global alliance. The mission's other purpose is to inspire millions of students and youngsters via this incredible mission.

Why Explore the lunar South pole?

The Moon holds the early history of record of nascent  Solar system Environment. Humanity has been exploring the Moon since the space exploration race started. From Pioneer 0 in 1958, which was the first-ever mission of the United States to the Moon to the latest Successful mission TESS in 2018. There have been over 120+ missions to Mars; we have acquired a lot of knowledge about our natural satellite. While several models explain the origin of this interstellar body, the Moon's history still needs further explanations. Extensive mapping of the lunar surface will help us study the variations in the composition of the Moon, which is the essential knowledge that will support the explanation of Moon's origin and evolution. Evidence of water units, discovered by Chandrayaan 1 and the extent of its distribution on the lunar surface and sub-surface also require further studies.

Mission Includes:

The mission includes a launcher, an orbiter, Lander and a rover, all developed domestically. The mission will be launched on 22nd July at 02:15 am.Chandrayaan-2 will land on Moon by September 6 or 7 near the South lunar pole, where no space mission has ever gone before. The Orbiter with Lander and rover will be launched onboard the advanced heavy rocket GSLV Mark III from the Sriharikota spaceport to shoot it in the earth's elliptical orbit at 170km perigee and 30,000km apogee for cruising towards the Moon over the next 16 days.ISRO has named the lander 'Vikram', after the founder of ISRO Vikram Sarabhai. They named the rover 'Pragyan', which means wisdom in Sanskrit.

The GSLV Mark-III will take Chandrayaan 2 to its designated orbit. This three-stage vehicle is India's most potent launcher to date; it is capable of launching 4 ton class of satellites to the Geosynchronous Transfer Orbit (GTO).

The Lander of Chandrayaan 2 is named 'Vikram' after Dr Vikram A Sarabhai, the Founder of Indian Space Research Organisation(ISRO). The Lander Vikram is designed to function for one lunar day, which is approximately fourteen earth days. Vikram has the ability to communicate with IDSN at Byalalu near Bangalore, as well as with the Orbiter and Rover(Pragyaan). The Lander is intended to execute a soft landing on the lunar surface. It weighs 1,471 kg and has Electric Power Generation Capability of 650W.

During the time of launch, the Chandrayaan-2 orbiter will be equipped to communicate with Indian Deep Space Network at Byalalu as well as the Lander Vikram. The orbiter will orbit the Moon for approximately one year and will be placed in a 100 X 100 km lunar polar orbit. Orbiter weighs 2,379 kg and has Electric Power Generation Capability of 1000W.

Rover of Chandrayaan-2 was named Pragyaan, which means wisdom in Sanskrit. It is a six-wheeled robotic vehicle. Pragyan can travel up to 500 meters, and it gains solar energy for its functioning. Pragyan can only communicate with the Lander Vikram. It weighs 27 kg and has Electric Power Generation Capability of 50W.

Searching for Water

The goal would be to explore the territory of the lunar surface and analyze crust samples for the signs of water and helium-3.Helium-3 is an isotope of helium and is limited on earth yet so plentiful on the Moon that it theoretically meets the global energy demands for 250 years if harnessed.
After 20 minutes of landing, the rover will send the pictures of the lunar surface. The landing area has been chosen in a way that it has no craters or boulders, and it is nearly flat with excellent visibility due to solar light.
Space agencies funded by the government are jolting with private missions to explore the cosmos. Amazon founder Jeff Bezos has announced that he's sending a spaceship to the Moon, and billionaires Elon Musk(My Idol) and Richard Branson are preparing to launch satellites and send astronauts and paying tourists into space.

Cost of the mission

ISRO is known as an agency of effectivity and affordable in space programmes. Scientists at ISRO are working harder to make space flight effective and affordable. The cost of Chandrayaan 2 mission is Rs 978 crore(approximately US$141 million), including Rs 603 crore(US$87.6 million) for the orbiter, lander, rover, navigation and ground support network and Rs 375 crore(US$54.5 million) for the heavy rocket GSLV Mk III.
The entire Mission cost is less than the budget of the latest Marvel film Avengers: Endgame ($350 million).

Next Priority:

ISRO's next priority is the $1.4 billion Gaganyaan mission, which intends to put three Indian "gaganauts" at least one of which will be a woman into the orbit.
