Chandrayaan 2

Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole. Further, the Rover will roll out for carrying out scientific experiments on the lunar surface. Instruments are also mounted on Lander and Orbiter for carrying out scientific experiments.
All the modules are getting ready for Chandrayaan-2 launch during the  window of July 09, to July 16, 2019, with an expected Moon landing on September 06, 2019.

CHANDRAYAAN MISSION                   


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 would have the prime responsibility for the orbiter and rover, while Roscosmos was to provide the lander.
The Indian government approved the mission in a meeting of the Union Cabinet, held on 18 September 2008 and chaired by  Prime Minister Manmohan Singh. The design of the spacecraft was completed in August 2009, with scientists of both countries conducting a joint review.
Although ISRO finalised the payload for Chandrayaan-2 per schedule, the mission was postponed in January 2013, and rescheduled to 2016 because Russia was unable to develop the lander on time. Roscosmos later withdrew in wake of the failure of the Fobos-Grunt mission to Mars, since the technical aspects connected with the Fobos-Grunt mission were also used in the lunar projects, which needed to be reviewed. When Russia cited its inability to provide the lander even by 2015, India decided to develop the lunar mission independently.
The spacecraft's launch had been scheduled for March 2018, but was first delayed to April and then to October to conduct further tests on the vehicle. On 19 June 2018, after the program's fourth Comprehensive Technical Review meeting, a number of changes in configuration and landing sequence were planned for implementation, pushing the launch to the first half of 2019. Two of the lander's legs got minor damage during one of the tests in February 2019. Chandrayaan-2 launch is tentatively scheduled for 14 July 2019, with the landing expected on 6 September 2019.


Chandrayaan - 2

The mission is planned to fly on a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) with an approximate lift-off mass of 3,877 kg (8,547 lb) from Satish Dhawan Space Centre on Sriharikota Island. As of June 2019, the mission has an allocated cost of 978 crore (approximately US$141 million) which includes 603 crore for space segment and 375 crore as launch costs on GSLV Mk III. Chandrayaan-2 stack would be initially put in a Earth parking orbit of 170 km perigee and 40,400 km apogee by the launch vehicle. It will then perform orbit raising operations followed by trans lunar injection using its own power.


The orbiter will orbit the Moon at an altitude of 100 km (62 mi).The mission will carry five instruments on the orbiter. Three of them are new, while two others are improved versions of those flown on Chandrayaan-1. The approximate launch mass will be 2,379 kg (5,245 lb). The Orbiter High Resolution Camera (OHRC) will conduct high-resolution observations of the landing site prior to separation of the lander from the orbiter. Interfaces between the orbiter and its GSLV Mk III launch vehicle have been finalised. The orbiter's structure was manufactured by Hindustan Aeronautics Limited and delivered to ISRO Satellite Centre on 22 June 2015.

Pragyan rover

The mission's rover is called Pragyan (Sanskrit: प्रज्ञानlit. 'Wisdom'). The rover's mass will be about 27 kg (60 lb) and will operate on solar power.The rover will move on 6 wheels traversing 500 meter distance on the lunar surface at the rate of 1 cm per second,performing on-site chemical analysis and sending the data to the lander, which will relay it to the Earth station.
  • Stereoscopic camera-based 3D vision using two NAVCAMs in front of rover will provide the ground team controlling the rovers a 3D view of the surrounding terrain and help in path planning by generating a digital elevation model of the terrain.
  • Control and motor dynamics - The rover will have six wheels, each driven by an independent electric motor. Four of the wheels will also be capable of independent steering. A total of 10 electric motors will be used for traction and steering.

Ummul Kher – A girl from the slums who achieved her dream of becoming an IAS officer

The touching story of Ummul Kher – A girl from the slums who achieved her dream of becoming an IAS officer

Ummul Kher
This is the story of Ummul Kher – a 28-year-old fragile girl with an angelic smile, who fought all odds for her education and proved herself worthy. Ummul is soon to join the Indian Administrative Service (IAS).
Ummul Kher

For Ummul, as much as she’d like it to be, her story is not a fairytale. Poverty and a genetic disorder have been her constant companion. The sky in Ummul’s world had been grey for the longest time. But nothing could shatter the woman’s hard will and determination. She knew she was destined to reach the stars and that the strings of fate were entangled around her delicate fingers. She was in charge of her destiny and nothing could come in between.

Education as top priority

Ummul was born and brought up in a slum in New Delhi. She had drainage for a river and the stink of garbage for atmosphere. Her dreams seemed just that – a dream, a distant one. Her father owned a tiny tea stall which barely met their needs. Ummul was then enrolled in a government school where she had completed her education up till grade 8. But when things did not seem to be working for the family, they decided to shut shop and move back to their hometown in Rajasthan.
Determined not to give up on her education, Ummul risked being abandoned by her family to stay back and focus on her studies. She wanted to become something in life and she knew education was the sole answer. Her parents were outright against her decision and therefore left her to fend for herself.
Because Ummul had performed exceptionally well in her studies, she received help from a teacher and got admitted in a private school. She got herself a small hut in the neighborhood of Trilokpuri and took tuitions in her free time to pay for necessities. Her students were kids of auto rickshaw drivers and iron smiths so she earned a meagre salary of INR 50 – 100 per student. It wasn’t much but she was doing just fine.
Ummul Kher

She passed 12th with flying colors and got admitted in Gargi College of Delhi University. She went ahead to finish her masters in International Relations from Jawaharlal Nehru University. Here, she cracked the Junior Research Fellowship (JRF) because of which she got a regular amount of INR 25,000 per month. Suddenly her luck seemed to be taking a turn. She didn’t have to work long hours to struggle for money and her efforts seemed to finally be paying off.

A bumpy path ridden with hurdles

But poverty wasn’t her only enemy. She also had to overcome her disorder. Ummul suffers from a genetic disorder called Fragile Bone Disorder. Her bones are weak and any minor injury could cause extreme pain and discomfort. She has suffered 16 fractures, 8 surgeries, and has even been on a wheelchair for months because of it but this only uplifted rather than dim her spirits

Living the dream

Despite all her shortcomings, Ummul has shown her true colors. She qualified for the UPSC exams in her very first shot with an overall Indian ranking of 420. This was the moment she had dreamt of and she worked her way to achieve it. She is ever so determined and proud of finally being able to realize her dream of becoming an IAS officer.

(CURRENT AFFAIR) 16 June celebrating as Father's Day

No comments :


History of Father's Day Festival as seen today is not even a hundred years old. Thanks to the hard work and struggle of Ms Sonora Louise Smart Dodd of Washington that just as we have set aside Mother's Day to honor mothers we have a day to acknowledge the important role played by the father. However, some scholars opine that Father's Day history is much older than we actually believe it to be. They say that the custom of honoring dad's on a special day is over 4,000 years old. There are a few more claims about the Father's Day origin about which we will learn in this page.

Earliest History of Father's Day

Scholars believe that the origin of Father's Day is not a latest phenomenon, as many believe it to be. Rather they claim that the tradition of Father's Day can be traced in the ruins of Babylon. They have recorded that a young boy called Elmesu carved a Father's Day message on a card made out of clay nearly 4,000 years ago. Elmesu wished his Babylonian father good health and a long life. Though there is no record of what happened to Elmesu and his father but the tradition of celebrating Father's Day remained in several countries all over the world.


The concept of celebrating Father's Day is very new in India. The idea of celebrating Fathers Day has been imported from western countries mainly US, perhaps less than a decade ago.
However, it is remarkable to note that the idea of observing a day in honor of fathers has been appreciated by Indians to a large extent. Today, millions of people in India observe Father's Day on the third Sunday of June by expressing gratitude for their father or men who are like father.

Father's Day Celebration in India

Father's Day in India
Father's Day celebration in India takes place in the same way as in UK or US though in a limited way. Awareness about Fathers Day festival is much greater in metropolitan cities and bigger towns due to the greater exposure of people to the western cultures in such places. But thanks to the rigorous advertising campaign launched by card companies and gift sellers the idea of celebrating Father's  day is fast catching on with people in smaller towns and cities of India.
Just as in UK and US people in India too, celebrate Father's Day by expressing gratitude and love for Papa. Children gift cards, flowers and other gifts of love to their dad to show their affection. Dining in restaurants or going out for picnic or movie is another common way of celebrating Fathers Day in India.
Several schools and cultural societies in India organize cultural programs on Father's Day. The idea behind such programmes is to inspire children to pay due respect to their dad and take care of them. Fathers are also encouraged to spend quality time with their children and instill in them noble values and manners.

History of Father's Day in US

Modern version of Father's Day celebration originated in United States of America and thereafter the tradition spread in countries around the world. The world owes thanks to Ms Sonora Louise Smart Dodd a loving daughter from Spokane, Washington as it is because of her struggle that Father's Day saw the light of the day.

The idea of Father's Day celebration originated in Sonora's mind when she per chance listened to Mother's Day sermon in 1909. Fairly mature at the age 27, Sonora pondered if there is a day to honor mother then why not for father? Sonora felt strongly for fathers because of the affection she received from her own father Mr William Jackson Smart, a Civil War veteran. Sonora's mother died while childbirth when she was just 16. Mr Smart raised the newborn and five other children with love and care.
Inspired by Ms Anna Jarvis's struggle to promote Mother's Day, Ms Dodd began a rigorous campaign to celebrate Father's Day in US. The Spokane Ministerial Association and the local Young Men's Christian Association (YMCA) supported Sonora's cause. As a result Spokane celebrated its first Father's Day on June 19, 1910. Though there was initial hesitation the idea gained gradual popularity all over US and Fathers Day came to be celebrated in cities across the country.

Looking at the heightened popularity of Father's Day in US, President Woodrow Wilson approved of this idea in 1916. President Calvin Coolidge too supported the idea of a national Father's Day in 1924 to, "establish more intimate relations between fathers and their children and to impress upon fathers the full measure of their obligations". After a protracted struggle of over four decades, President Lyndon Johnson signed a presidential proclamation declaring the third Sunday of June as Father's Day in 1966. Then in 1972, President Richard Nixon established a permanent national observance of Father's Day to be held on the third Sunday of June. Sonora Smart Dodd was honored for her contribution at the World's Fair in Spokane in 1974. Mrs. Dodd died in 1978 at age 96.

U.S. offers India armed version of Guardian drone


US approves sale of armed drones, offers missile defense systems to India

U.S. offers India armed version of Guardian drone

The Trump administration has approved the sale of armed drones to India and has offered integrated air and missile defence systems aimed at helping the country boost its military capabilities and protect shared security interests in the strategically important Indo-Pacific region.

The approval-cum-offer from the US came in the aftermath of the February 14 Pulvama terrorist attack in which 40 Indian soldiers were killed and the increasing militarisation and assertiveness of China the Indo-Pacific ocean.

According to the officials, the Trump administration is ready to offer its best defence technologies to India.

                           Armed Drones

"The United States approved the sale of the armed drones to India. We have offered integrated air and missile defense technology to India," a senior White House official told PTI.

The official, who spoke on the condition of anonymity, did not reveal when the sale of the armed drones to India took place.

During the June 2017 meeting between Prime Minister Narendra Modi and President Donald Trump, the US had agreed to sell surveillance version of the Guardian drones to India.

India was the first non-treaty partner to be offered a MTCR Category-1 Unmanned Aerial System – the Sea Guardian UAS manufactured by General Atomics.

PM Modi & President Trump 

While the deal is yet to see the light of the day, mainly because of the delay in decision making process by India in view of the general elections, the US in recent months informed New Delhi about its decision to sell armed version of the Guardian drones.

The ball is now in India's court, a defense industry source told PTI.

The deal, if it happens, could be in the range of over USD 2.5 billion, the industry source said.

Close on the heels of armed drones, which will have its implications in South Asia and Indo-Pacific region, the US has also offered its integrated defense missile capabilities to India.

While officials are tight-lipped about it, the offer is said to be about two of its latest systems: Terminal High Altitude Area Defense system (THAAD), which is highly effective when used against long-range ballistic missiles and Patriot Missile defense system.

India, which has already signed an agreement with Russia to purchase S-400 missile defense system, is yet to respond to the American offer. The American offer, which came of its own, is currently being studied in New Delhi.

"We want India to have our best technology, and we want to see India improve its defense capabilities so that it can be a net provider of security in the broader Indo-Pacific region," the senior White House official, told PTI.

In a fact sheet on "US Security Cooperation with India" issued this week, the State Department joined the White House in trying to help strengthen its defense capabilities mainly due to the Indo-Pacific region.

"India plays a vital role in the US vision for a free and open Indo-Pacific," said the fact sheet issued by the Bureau of Political Military Affairs of the State Department.

Towards this end, in 2016, the US designated India as a Major Defense Partner.

Commensurate with this designation, India last year was granted Strategic Trade Authorization tier 1 status, which allows India to receive license-free access to a wide range of military and dual-use technologies that are regulated by the Department of Commerce, it said.

With a Communications, Compatibility and Security Agreement (COMCASA) and other enabling agreements now in place, US-India defense trade cooperation continues to expand, it said.

Some of the recent top defense sales to India include: MH-60R Seahawk helicopters (USD 2.6 billion), Apache helicopters (USD 2.3 billion), P-8I maritime patrol aircraft (USD 3 billion), and M777 howitzers (USD 737 million).

President Donald Trump 

The State Department is also pushing for Lockheed Martin F-21 and Boeing F-18/A – two state-of-the-art fighter aircraft that India is currently evaluating.

"These platforms provide critical opportunities to enhance India's military capabilities and protect shared security interests in the Indo-Pacific region," the State Department fact sheet said.

"We are now reaching agreements that we did not have before that allow us to consider sales that were incomprehensible five years ago," a senior State Department official told a group of reporters last week.

The choices that are made now will establish the framework for the future, the official said.

"We certainly have the ambitions for the broadest possible, deepest possible military relationship with India," said the official requesting anonymity.
