In the early 19th century, a monumental scientific project began that would leave a profound mark on the Indian subcontinent. The Great Trigonometrical Survey of India, initiated in 1802, was not merely about cartography; it was a groundbreaking venture that reshaped the landscape of India through precision, innovation, and vision. Spearheaded by British infantry officer William Lambton under the East India Company, this survey transformed the understanding of the subcontinent’s geography and had far-reaching impacts on administration, economy and cultural heritage. The Great Trigonometrical Survey officially commenced on 10 April 1802, with the measurement of a crucial baseline near Madras (now Chennai). Major Lambton, who was tasked with leading this ambitious project, carefully selected a flat plain for the initial measurement.

The baseline stretched 7.5 miles (12.1 km) and was marked by St. Thomas Mount at the north and Perumbauk Hill at the southern end. This baseline was the first step in a meticulous process that aimed to map the vast Indian subcontinent with unprecedented accuracy. Lambton’s choice of a flat plain for the initial baseline was strategic. Accurate measurements were crucial for the success of the survey, and a flat, unobstructed baseline allowed for more precise calculations. The work began with the meticulous measurement of this baseline, which would serve as the foundation for the extensive triangulation network that followed. The Great Trigonometrical Survey utilized advanced trigonometric techniques to measure distances and angles across the vast expanse of India.

The method involved creating a network of triangles, using the baseline measurements as a reference point. By measuring angles and distances within these triangles, surveyors were able to map the terrain with remarkable precision. One of the most notable achievements of the survey was the accurate measurement of the meridian arc from the southern tip of India to Nepal. This endeavour required surveying through varied and challenging terrain, including the Himalayan mountain range. The precision achieved in this measurement allowed for the calculation of the Earth’s circumference with astonishing accuracy and contributed to global scientific knowledge. For the British East India Company, the survey was more than a scientific undertaking; it was a crucial tool for effective administration and control. The detailed maps produced by the survey enabled the British to manage the vast and diverse regions of India with greater efficiency.

Accurate geographical information facilitated better planning of infrastructure projects such as roads, railways, and irrigation systems. The survey’s precise maps were instrumental in the collection of land revenue, as they provided detailed information about land use and boundaries. This information was crucial for implementing administrative policies and managing the economic resources of the subcontinent. The improved accuracy in mapping also played a key role in the strategic planning of military campaigns and the consolidation of British rule across India. The detailed maps created by the Great Trigonometrical Survey had a transformative effect on the Indian economy. The accurate depiction of geographical features facilitated the construction of infrastructure that was vital for economic development.

Railways, roads, and irrigation systems were planned and executed with greater precision, fostering economic growth and integration. The expansion of the railway network, for instance, connected previously isolated regions, facilitating trade and commerce. This connectivity helped create a unified market across the subcontinent, stimulating economic activity and development. The survey’s work in mapping resources and land use patterns also contributed to the optimization of agricultural practices and resource extraction, further boosting economic growth. Beyond its immediate practical benefits, the Great Trigonometrical Survey left a lasting legacy in the fields of science and culture. The survey’s precision and methodology advanced the science of geodesy and set new standards for geographic measurement. The accurate geographic coordinates established by the survey influenced future scientific research and exploration. Culturally, the survey contributed to a deeper understanding of India’s diverse geography and historical landmarks. By documenting and mapping ancient sites and natural features, the survey helped preserve India’s cultural heritage.

The detailed maps provided insights into the region’s historical and cultural landscape, enriching the appreciation of India’s heritage. The significance of the Great Trigonometrical Survey is commemorated by several memorials across India. One notable example is Lambton’s Memorial in the village of Perumbauk, which marks the site where the initial baseline measurement began. These memorials serve as a testament to the monumental effort and achievements of the survey, honouring the contributions of Major Lambton and his team. The Great Trigonometrical Survey of India was a landmark project that reshaped the Indian subcontinent in multiple dimensions.

From its meticulous beginning with the measurement of a 7.5-mile baseline near Madras to its profound impacts on administration, economy, and culture, the survey was a transformative endeavour. Its legacy endures through the precise maps it produced, the infrastructure it helped develop, and the scientific advancements it inspired. The Great Trigonometrical Survey stands as a testament to the power of scientific innovation in shaping the course of history and transforming societies.

GLOBAL: NATIONAL / SPACE : 40 years after astronaut Rakesh Sharma, Shubhanshu Shukla is the first Indian to travel to space: Here’s how is gearing up for ISS

In a monumental step for India’s space program, Group Captain Shubhanshu Shukla of the Indian Air Force (IAF) will pilot the Axiom-4 (Ax-4) mission to the International Space Station (ISS) in 2025, TOI has reported.

This mission will mark India’s first human presence aboard the ISS and its second government-sponsored human spaceflight in more than four decades, following Wing Commander Rakesh Sharma’s 1984 mission with the Soviet Union.

The Ax-4 mission is the result of a collaborative initiative between India and the United States. More than a year ago, during an official state visit to the U.S., Prime Minister Narendra Modi announced that an Indian astronaut would travel to the ISS. Following this, the Indian Space Research Organisation (Isro) signed a spaceflight agreement with Axiom Space, a leading American company in human spaceflight services.

Shukla, an experienced IAF test pilot, will be part of an international crew, with fellow Indian astronaut and backup pilot Group Captain Prashanth Nair also from the IAF. The mission will be commanded by renowned astronaut Peggy Whitson. Sharing details of Shukla’s responsibilities, Whitson told The Times of India, “As the Ax-4 pilot, Shukla will assist me in conducting essential spacecraft operations, such as navigation and docking procedures. Training will prepare him to handle emergencies and perform critical system checks. Additionally, Shukla will support scientific research by setting up and managing microgravity experiments.”

The Ax-4 mission is expected to play a crucial role in advancing India’s space capabilities, particularly as the country prepares for its own crewed mission, the Gaganyaan project. In a recent Instagram Live session, Isro Chairman S Somanath revealed that the Indian astronaut will conduct five experiments aboard the ISS as part of the Ax-4 mission, gaining valuable experience in space operations and international collaboration.

Whitson further elaborated on the rigorous training that Shukla and his fellow crew members are undergoing. “We work closely with NASA and other international space agencies to ensure smooth integration with ISS. Additionally, Axiom invests in cutting-edge medical research and technology to monitor and maintain astronaut health during missions,” she explained. “By leveraging these strategies, Axiom Space aims to mitigate risks and ensure the success of our missions.”

Training for the mission will be conducted at multiple facilities, including NASA, SpaceX, the European Space Agency (ESA), and the Japan Aerospace Exploration Agency (JAXA). The preparation covers all aspects of the mission, from safety protocols and health management to ISS systems operations. According to Whitson, “We practise in ISS mockups, reviewing procedures and enacting emergency scenarios to ensure we’re ready for any situation.”

The Ax-4 mission will utilize SpaceX’s Falcon 9 rocket and Dragon spacecraft, known for its advanced life support systems and automated docking capabilities. This will ensure a safe journey for the crew, who will spend up to 14 days aboard the ISS.

Joining Shukla and Whitson on the mission are specialists Slawosz Uznanski from Poland and Tibor Kapu from Hungary. Uznanski, an expert in radiation testing and space electronics, is a member of ESA’s 2022 Astronaut Reserve Class, while Kapu, selected for Hungary’s Hunor Astronaut Programme, brings his expertise in space radiation protection and pharmaceutical research.

Whitson emphasized the global significance of the Ax-4 mission, saying, “The Ax-4 crew will spend up to 14 days aboard ISS. This mission will realize the return to human spaceflight for India, Poland, and Hungary, marking each nation’s first mission to the space station in history and second govt-sponsored human spaceflight mission in over 40 years. This mission emphasizes how Axiom Space is redefining the pathway to low-Earth orbit and elevating national space programs globally.”

In addition to strengthening international cooperation, the Ax-4 mission will support the development of commercial space activities. “Axiom Space missions play a pivotal role in advancing international cooperation in space exploration. By partnering with organizations like ESA, Isro, and Hunor, Axiom fosters collaboration in human spaceflight, research, and technology development,” Whitson explained.

As Group Captain Shubhanshu Shukla gears up for this groundbreaking mission, India is poised to make significant strides in space exploration, bolstering its role on the global stage.

NATIONAL: INNOVATION for VISUALLY IMPAIRED : ### Umang Sharma, an 11th Grader, Creates Affordable Keyboard for the visually impaired using AI

Umang Sharma, a junior student of Class 11 at Princeton Day School, has developed an affordable keyboard for the visually impaired using artificial intelligence (AI). His interest in AI, robotics, and engineering, coupled with his passion for coding, led him to improve Braille technology with the help of experts. His success in creating this innovative keyboard is a result of his deep interest in computer building and technology.

Globally, around 284 million people are visually impaired, 39 million of whom are completely blind. A staggering 70% are unemployed, and 90% are illiterate, which significantly limits their opportunities. Umang’s journey began when he discovered that Braille keyboards cost over $7,000, a price he found to be unaffordable for many. Realizing the need for a cheaper alternative, he conducted research but found no better options.

A significant challenge faced by the visually impaired is the lack of access to technology, which contributes to high unemployment and illiteracy rates. Umang identified this as a vicious cycle, where the inability to afford technology like Braille keyboards prevents visually impaired individuals from securing jobs, yet employment is necessary to purchase such tools.

Current market solutions for Braille keyboards include audio keyboards built into operating systems, physical Braille devices, and one-time-use stickers for standard keyboards. After analyzing these options, Umang identified key issues, such as high cost, usability, and durability. He designed prototypes, consulted Braille experts, and made improvements to address these shortcomings.

The result is an affordable, user-friendly keyboard for the visually impaired, priced at just $10, and nearly free if donated keyboards are used. The keyboard utilizes 3D-printed keys that are durable and can be easily attached to any keyboard.

Umang presented his project at two workshops held at the National Blind Association, Delhi, and the Silver Lining Blind School, where visually impaired youths from underprivileged backgrounds tested the keyboard. The feedback confirmed the effectiveness of the design, particularly for blind students and young children learning Braille. The keyboard helped improve their typing speed and key recognition, proving to be a faster alternative compared to conventional keyboards that require pressing each key to find the right one.

The National Blind Association, Delhi, praised Umang’s efforts, and the Silver Lining Blind School expressed gratitude for his dedication and hard work in serving the visually impaired. Umang has donated over 20 keyboards and is working on providing more units, benefiting over 250 students.

Following this success, Umang plans to distribute his innovative Braille keyboards to blind schools globally and has founded a non-profit organization called “Zedable” to support his mission.

INTERNATIONAL: REGIONAL – ASIA / SPORTS – FIELD HOCKEY : India Wins 05th Asian Hockey Champions Trophy Title; Beats China Courtesy Jugraj Singh’s Solitary Goal

India’s hockey team extended their winning streak in the Asian Champions Trophy by winning the tournament for the fifth time beating China 1-0 in the final. Jugraj Singh came up with an impressive field goal and helped the team seal a victory.

Indian hockey team continued their domination in the Asian Hockey Champions Trophy beating China 1-0 in the final. With a triumph at the Moqi Hockey Training Base, India won the title for the fifth time in the history of the tournament. Also, they were the only undefeated team in the tournament winning all of the seven matches they played.

Jugraj Singh was the difference between the two sides as he scored the solitary goal of the fixture in the fourth quarter as skipper Harmanpreet Singh provided an assist for the Indian defender. The decisive goal from Jugraj came in the 51st minute.

India and China had locked horns against each other in the tournament with the former winning the fixture by 3-0. Harmanpreet and Co. were coming into the game as favourites considering a superior ranking and previous record. However, China didn’t give up without a fight and made India fight hard to lift the title.

India triumphs after a fierce battle

The first real chance for India came in the ninth minute but the Chinese defence was up to the task to save it. When India got another chance, Harmanpreet missed the target. China looked stronger in the first quarter as they tasted Indian goalkeeper Krishan Pathak multiple times. China parked the bus in the second quarter but India had a chance in the 27th minute. Harmanpreet took aim at the goal but the ball bounced off the post. By the half-time, the scoreline was reading 0-0.

India started on an attacking note in the third quarter and produced a string of fine attacks but the Chinese defence was resolute once again. The first-time finalists created a couple of chances in the third quarter but the Indian team kept them at bay. The deadlock was finally broken in the 51st minute as Harmanpreet made a stellar run in the D and set up a goal for Jugraj who provided a brilliant finish.

India wins the Asian Champions Trophy for the fifth time

This was India’s record-breaking fifth title as they won the tournament earlier in 2011, 2016, and 2023. In 2018, they were the joint winners along with Pakistan who are the second-most successful side. Pakistan has won the tournament thrice while South Korea won the title in 2021. Notably, it was the best-ever tournament run for China as they made it to the final of the tournament for the first time.

Pakistan finished in third place

Pakistan beat South Korea by 5-2 in the match for the third position. Pakistan lost against China in the semi-final but made up for their loss by finishing the tournament at the third spot in the tournament.

INTERNATIONAL: ARTS : INDIA’s HUMAN- WILD LIFE CO-EXISTENCE- Installation in New York, USA : A herd from Nilgiris takes over New York, throws spotlight on a jumbo problem

The statues have been conceptualised by Gudalur-based The Real Elephant Collective (TREC) and sculpted from boiled Lantana by 200 tribal artisans from the Nilgiris, who make up the Coexistence Collective.

At the elegant Meatpacking district of New York, where shopfronts have names such as Rolex, Gucci and Hermes, a different kind of display is attracting the crowds — a herd of 100 wild elephants that has made its way from Gudalur in Tamil Nadu’s Nilgiri hills to the US.

In the parade are kind-eyed matriarchs, playful calves, bulls with outstretched trunks and grand tuskers. These elephants are made of Lantana, one of the 10 worst invasive plant species in the world, that’s making food scarce for these giants in the forests and driving them out.

The statues of the pachyderms make up The Great Elephant Migration, a public art installation that has been to Kochi, London and Bengaluru before trumpeting into New York, where it is one of the biggest such works on display. The installation, which highlights the importance of human-wildlife coexistence and the need to protect Asian elephants, is the brainchild of a UK-based conservation group, Elephant Family USA.

The statues have been conceptualised by Gudalur-based The Real Elephant Collective (TREC) and sculpted from boiled Lantana by 200 tribal artisans from the Nilgiris, who make up the Coexistence Collective. “The scene in New York is hard to describe. It is amazing to see hundreds and hundreds of people, all so moved by the elephants. People who live nearby keep coming back and volunteering to look after the elephants,” says Tarsh Thekaekara, a researcher and conservationist who works on human-animal inclusive models of nature conservation.

Tarsh, who co-founded TREC with Subhash, Subhra Nayar and Tariq Thekaekara, says,“The logistics of travelling with the elephants is not difficult. The challenging part is to push the message of coexistence. Traditional conservation assumes that we need to protect only the pockets of forests and ignore the rest. That is not working. Animals are coming out of forests everywhere in the world.”

And who would know about human-animal conflict better than the tribals? Gudalur lies in the middle of the Western Ghats, located between Karnataka, Tamil Nadu and Kerala, and close to four forest reserves, Mudumalai, Wayanad, Bandipur and Mukurthi. Locals here have grown up seeing elephants and leopards around their houses, but fatal elephant attacks have risen over the past few years.K

Ramesh Madan, who is in his 30s and belongs to the Betta Kurumba tribe, says, “When I was a child, an elephant or two would come (to our houses) in the jackfruit season. I have never known so many elephants to come near our houses, as has been happening in the last few years. When we go into the forest to collect things, I can see that Lantana has taken over large parts. It is the reason why elephants are coming out of the forest.”

A weed that sports clusters of small, colourful flowers, Lantana camara was brought to India by the British as an ornamental plant in the 1800s. According to a study in the Journal of Applied Ecology in October 2023, Lantana has penetrated over 5,74,186 sq km of India, including 50 per cent of the country’s natural areas.

In a takeover by Lantana, which is fast-growing and toxic, a forest gets completely matted, not allowing for growth of any other plant species. Deprived of their food sources, animals are pushed out of forests into urban areas. Moreover, as Lantana goes up trees, forest fires become more widespread. TERC co-founder Subhash says, “If trees burn, they don’t come back as quickly as grasses.”

Tarsh, Subhash, Subhra and Tariq, who were schoolmates, came back to Gudalur to contribute to their home. Between 2013 and 2015, TREC started a mapping exercise at the four forest reserves in collaboration with the Shola Trust in Gudalur. “Initially, the forest department was in denial and we had to physically ascertain how bad the Lantana problem was. We found that 30-40 per cent of the forest was taken over by Lantana. If 30 per cent of land area is not viable for animals, it could be the reason elephants were coming out of forests,” says Subhash.

It was Tarsh and Subhra who first came across Ruth Ganesh, a trustee of the Elephant Family. The organisation creates outdoor figures of elephants to draw attention and finances for the protection of Asian elephants. TREC, which was looking for fresh ideas, wondered if it could make life-size elephant statues out of Lantana. “What was beautiful in that whole exercise was that the indigenous communities did not need to be taught to make the elephant figures,” says Subhash.

In the workshop above his office in Gudalur, artisans from the Soliga, Betta Kurumba, Kattunayakan and Paniya tribes are immersed in creating elephant statues. Each model is a likeness of a real wild elephant that the tribals coexist with. Subhra, who has a background in puppetry, is the resident designer. Using photographs, she constructs metal structures of elephants over which the artisans place strips of Lantana, which are cut out from the forest by a group. “Lantana are boiled and used for the sculptures,” says Tarsh.

The pieces are sold by TREC to partners, who auction them in the US and the UK, among others. The profits go into supporting human-wildlife coexistence projects across the world, including India. In India, the funds are disseminated through the Coexistence Consortium, which comprises ecologists, anthropologists, geographers and conservationists, among others, who promote the concept of coexistence.

M Ranjini, also from the Betta Kurumba tribe, manages the production of the Lantana elephants. “We feel hopeful that the New York exhibition is spreading our message,” she says.

India’s policy on invasive species is, according to Delhi-based naturalist and author Pradip Krishen, “patchy at best and close to nil at worst”. “We are one of the last countries in the world to have an official Invasive Alien Species (IAS) list. In Delhi, where I live, the forest department stands by while a highly invasive tree like subabool (Leucaena leucocephala) fills up the Ridge and unoccupied verges in the city. The invasive vilayati kikar accounts for more than 90 per cent of the trees inside the huge Central Ridge in the heart of the city. Delhi’s Tree Act is completely silent about invasive plants. On a scale of 1 to 10, I would say that awareness might be 4 or 5, but effective action and policy remain abysmally low at 1 or 0.5,” he adds.

Krishen says that Lantana — like Chromolaena — has proliferated under the noses of forest authorities. “I have heard foresters say that Lantana is being unnecessarily demonised and that it provides habitat for small animals like hares and pigs, as well as food for bears, butterflies, and so on. This needs to be weighed against the harm Lantana does to natural habitats, such as pushing out native plant species, reducing forage for wild ungulates (animals with hoofs), having many deleterious effects especially on the herbaceous layer and greatly reducing biodiversity. The areas most affected are dry deciduous forests, which includes all of northern India upto the sub-Himalayan zone, all of Central India, parts of the arid zone in the west excluding the Thar desert and along the Eastern Ghats,” he says.

Subhash adds that, for generations, tribal communities managed forests. “After the Wildlife Protection Act 1972, they were stopped from accessing forests. Controlled forest floor fires are one of the ways indigenous communities manage forests. That helped because grasses grew well and so herbivores did well. With Lantana taking over the forest, the viability of forests was reduced. We would like indigenous communities to access forests so that they can actively participate in its management. This became another driver for us to get involved,” he says.

Tarsh adds, “If we carry on with the traditional model, we are creating pockets of forests that are being taken over by the Lantana. We are destroying the rest of the world and creating unhealthy environments for ourselves to live in. That is what we have to change. It is the vision that we are pushing overall with the Lantana elephants and it is not easy for people to grasp. They see the elephant, are amazed by it and take home the word ‘coexistence’. But, slowly, coexistence is a bigger message that we will be driving.”

INTERNATIONAL: NATIONAL: SPACE RECORDS: Historic first! India’s Chandrayaan-3 records more than 50 moonquakes. Here’s what it means

The researchers have identified more than 50 instances in which it was observed that the seismic signal had significant amplitude in comparison to the expected background levels.

In a historic achievement, Chandrayaan-3 became the first lunar mission to have detected more than 250 seismic signatures from the south pole of the Moon, since the Apollo missions.

These 250 seismic signals included 50 unique signals that are likely to have links with moonquakes, which refer to the earthquake on the lunar soil.
 
This is the first time seismic data has been collected from the South Pole of the lunar surface and also the first time such an activity has been recorded since the Apollo missions.

According to the media reports, 250 seismic signatures have been detected by the Instrument for Lunar Seismic Activity (ILSA) aboard the Vikram Lander during its operational period from August 24 to September 4, 2023, between the coordinates of 69.37 degrees south and 32.32 degrees east.

In 2023, the India Space Research Organisation (ISRO) said that the ILSA payload on Chandrayaan 3 Lander has been able to record the movements of Rover and other payloads.

The ILSA payload is the first Micro Electro Mechanical Systems (MEMS) technology-based instrument on the moon that utilises sensors manufactured with cutting-edge silicon micromachining technology.

All about 250 seismic signals detected by Chandrayaan-3

Among the 250 seismic signals, nearly 200 of them were said to have been produced by different mission activities like the Pragyan rover’s movements or the operation of scientific instruments like the ChaSTE thermal probe or Alpha Particle X-ray Spectrometer (APXS).

However, the remaining 50 signals were classified as “uncorrelated” and the scientists were not able to draw a connection between them and any mission-related activities. This raised the possibility of these signals being produced from real moonquakes.

These findings related to the moonquakes were mentioned in a recent paper published in ICARUS, which is a famous scientific journal.

Commenting on the findings, LEOS Director Sriram said, “Out of the 250 seismic events, about 200 correlate with Pragyan’s movements or other instrument operations. The remaining 50 signals do not align with any known activities, warranting further investigation to understand their origins.”

The study emphasised that the longest continuous seismic signal recorded had lasted 14 minutes.

GLOBAL: SPORTS: India Ends Paris Paralympics 2024 With 29 Medals. Pakistan, China Got…

India finishes the Paris Paralympics 2024 campaign with a total of 29 medals – seven golds, nine silvers and 13 bronze.

The Paris Paralympic Games 2024 concluded for India on Sunday, with Pooja Ojha the final athlete in action. Ojha failed to qualify for the women’s kayak 200m final and bowed out of the competition. As a result, India’s medals tally at the Paris Paralympics ended at 29 — seven golds, nine silvers and 13 bronze, making it the most rewarded campaign for the country. Courtesy of the 29 medals, India stood at the 18th position in the points table. Pakistan, who were also competing win the event, ended the campaign joint-bottom at the 79th position, with just a solitary bronze to its name.

India did very well in the 2024 campaign, beating top nations like Switzerland, Belgium, South Korea, Turkey, Argentina, etc. to finish the Paris Para Games among the top 20 countries in the world.

In comparison to India, the traditional heavyweights at the Paralympic Games — China, Great Britain, USA, Italy, etc. did very well gain, finishing among the top 10 nations. India, having shown significant progression in Paris, would be keen to produce an even better show in the 2028 LA Para Games. 

On Saturday, India earned its 29th and final medal of the Paris Paralympic Games through Navdeep Singh who clinched gold medal in men’s javelin throw F41 classification.

Navdeep, who competes in the classification meant for athletes of short stature, originally ended with a silver after he upstaged world record holder Sun Pengxiang of China with a 47.32m throw.

However, that was upgraded to an unprecedented gold after Iran’s Sadegh Beit Sayah was disqualified for repeatedly displaying an objectionable flag. Pengxiang (44.72m) finished with a silver.

Sayah had managed to nose ahead of the field with a new Paralympic record of 47.64m in his penultimate throw but lost the medal owing to his antics.

The International Paralympic Committee rules bar athletes from making any political gestures at the event and Sayah was thrown out of the final results for unsporting/improper conduct.

At the same venue, Simran, accompanied by her guide Abhay Singh, clocked an impressive personal best of 24.75sec to finish with a bronze in the women’s 200m (T12) event.

The 24-year-old from Delhi, who was found to be visually impaired at the time of her premature birth, is the reigning world champion in this event. She had finished fourth in the 100m competition of the ongoing Games and Saturday’s medal helped her redeem her campaign.

Track-and-field has contributed 17 medals to this tally, four of them gold. The country is placed 15th in the overall standings, led by China with a whopping 208 medals, including 90 gold.

For Navdeep, the gold makes up for the fourth-place heartbreak he endured in the Tokyo Games.

An inspector in the Income Tax Department, Navdeep has medalled five times at the national level since taking to the sport in 2017. He won a bronze in the para-world championships earlier this year.

Simran, on the other hand, won two silver medals at the Asian Para Games in Hangzhou last year and secured three gold medals in the 100m, 200m, and long jump at the inaugural Khelo India Para Games last December.
