CHANDRAYAAN-2

BY SHRUTI RAJPUT,
                - 7 SEPTEMBER, 2019

CHANDRAYAAN-2 MISSION FAILED

 For the first time in the history, the attempt was made 
of sending a satellite to explore the uncharted south

pole of Moon (celestial body).
India is the first country to make the attempt.

ISRO successfully launched the 3,840 kg CHANDRAYAAN-2 satellite into earth's orbit on July 22 and by August 20 the spacecraft had 
successfully entered the lunar orbit.
On August 22, ISRO realeases the first picture of moon captured by it.

Chandrayaan-2 had several science payloads to expand the lunar scientific knowledge through detailed  study of topography, seismography, miner identification and distribution, surface chemical composition, themi-physical characteristics of top soil and composition of tenuos lunar atmosphere, leading to a new understanding of the origin and evulation of the Moon. It comprised of three segments- the orbiter (weighing 2,379 kg, eight payloads), 'Vikram'(1,471 kg,  four payloads),
and 'Pragyan' (27 kg, two payloas).


On 12 November, 2007, representatives of the Russian Federal Space Agency (Roscosmos) and ISRO signed an agreement for the two agencies to work together on the Chandrayaan-2 project. ISRO had the responsibility for the orbiter and rover, while Roscosmos wah to provide the lander. The Indian government approved the mission in a meeting of the Union cabinet chaired by PrimeMinister Manmohan Singh, held on 18 September, 2008.

This mission was launched by Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) 
with allocated cost of ₹978 crore which includes ₹603 crore for space segment and ₹375 crore as launch costs on GSLV Mk III.

All was going well with the 1,471 kg Vikram that began its descent at about 1.38 a.m. on Saturday from an altitude of 30 km at a velocity of 1,680 metres per second. ISRO Chairman K. Sivan said that the performance of the lander was as per the plan till it was 2.1 km from the moon surface. The communication link got snapped after that, he added. It was seen that Vikram slightly changed from its planned path and then the communication link got snapped.

 Well, it was a heartbreaking for all but for all Indians, it was a very proud moment to say that the mission was 95% completed and rest 5% doesn't matter to us.

ISRO WOMEN SCIENTISTS

WHY ISRO NEEDS MORE WOMEN TO CONQUER THE MOON?  - BY SHRUTI RAJPUT  “FEMINISM”- Word of the year 2017. This word had made a strong impact on the lives of people from last 2 years. But it still leaves some space for society to question the ability of women to stand on their own. “Oh, you are a woman, Do you really want to do this?” “What? How society is going to react if you fail at this? ” “This field is for men.” Blah Blah !!  These are some questions and mindsets which almost all the women still go through. But inspite of all those negativites women still grow and shine in all the fields let it be business, finance, politics, sports, film industry, teaching, DJ, bartenders, army, transport and what not.
