'Dogfight' In Space At The Speed Of 29,000 kmph: ISRO Shows How It's Done
Last Updated:
India's ISRO achieved a milestone with the SPADEX mission, simulating a space dogfight between satellites at 28,800 km/h, showcasing advanced space defense capabilities
Just weeks after the United States accused China of simulating a high-stakes 'dogfight' in space, India has quietly pulled off a technological feat of its own, one that not only demonstrates scientific prowess but hints at strategic readiness for the future of orbital defence.
Under the ambitious SPADEX (Space Docking Experiment) mission, the Indian Space Research Organisation (ISRO) achieved what few nations dare to attempt: two Indian satellites—SDX 01 and SDX 02—were successfully manoeuvred to face one another in orbit, closing in at speeds nearing 29,000 km/h. What followed was nothing short of a simulated space confrontation, conducted with breath-taking precision.
Initially launched to test autonomous docking and undocking capabilities, the SPADEX mission had already achieved its primary objectives. However, with nearly half of their onboard fuel reserves still available, ISRO scientists saw an opportunity to push the boundaries further. What they orchestrated next resembled an aerial dogfight, but in the vacuum of space.
In an unprecedented move, both satellites were guided to approach each other head-on, mimicking high-speed combat manoeuvres akin to fighter jets locked in a mid-air drill. At an orbital velocity of 28,800 km/h, around 28 times faster than a commercial aircraft, the exercise was described by ISRO as 'technically complex and extraordinarily challenging".
This demonstration is more than a marvel of scientific ingenuity; it hints at India's quiet preparation for the evolving domain of space security, often dubbed the next frontier of warfare.
Earlier this year, the United States had raised alarm bells, accusing China of weaponising space by simulating dogfights with satellites, an act many viewed as a potential military provocation. In contrast, India's exercise, while echoing the technical nature of such manoeuvres, was conducted in a calm, deliberate, and scientific context.
Yet the implications are clear: India now possesses the technological maturity to engage in high-precision orbital operations, asserting itself as a rising power in space defence capabilities.
A Stark Contrast With Pakistan
While India advances in orbital control and autonomous docking technology, Pakistan continues to rely on China and the United States for basic GPS functionality. Bereft of its own satellite docking infrastructure or deep-space R&D, Islamabad is nowhere near fielding a mission like SPADEX.
This successful experiment not only marks a leap forward for India in terms of space exploration and satellite autonomy, it also sends an unmistakable message: India is preparing not just for terrestrial challenges, but for those in orbit as well.

As debate over coding in Sanskrit rages, DU introduces course blending ancient language with web development
New Delhi: Amid the debate around Sanskrit being a suitable language for coding — with some even citing Nasa's supposed use of the ancient language — Delhi University has introduced a course that brings the idea closer to the classroom. Offered by DU's Department of Sanskrit as a discipline-specific elective paper, titled "Computer Applications for Sanskrit", the course aims to equip students with modern computing techniques to develop tools using the Sanskrit language. Discipline-specific electives are optional courses that students can select from a range of available choices. This particular course will be accessible as an elective option to all Sanskrit students enrolled across various colleges in DU. Subhash Chandra, a faculty member at the Sanskrit department who developed the course and teaches computational linguistics, said the aim is to show students how Sanskrit can be integrated with technology. "We also have a website where we display some tools that we have developed using coding in Sanskrit. Some of these include language analysers, grammar checkers, speech tools — similar to those in Hindi that convert speech to text — and a Sanskrit research database. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Trading CFD dengan Teknologi dan Kecepatan Lebih Baik IC Markets Mendaftar Undo In this course, we will teach students coding to develop such tools," he said. The course syllabus will cover web-based tools development, Hypertext Markup Language (HTML) and webpage creation, alongside Unicode typing in Devanagari, OCR applications, and text digitisation and preservation. It will introduce students to interactive Sanskrit learning platforms and discuss the need for such tools in Sanskrit education. The module also includes e-learning concepts and multimedia basics. A dedicated section on Unicode will focus on typing in Devanagari script (alphabet used for Sanskrit, Hindi and other Indian languages), introducing students to relevant software and keyboard tools. Another unit is centred on the tools and techniques used for text processing and preservation of Sanskrit texts. The final unit explores Optical Character Recognition (OCR) applications for Sanskrit and other Indian languages, offering insights into the current technologies and developments in the field. While the course does not teach full-fledged programming, it introduces basic coding and digital skills to help students create interactive tools and platforms in Sanskrit — aligning, in part, with the broader narrative of giving ancient Indian languages a technological future. It is open to fourth-semester students with a working knowledge of Sanskrit and draws from tools developed by DU's Computational Linguistics Group and texts on software theory and logic. The objective of the paper, as stated in the syllabus, is to "introduce the current researches and developments in Sanskrit computing. The primary emphasis will be on tools and techniques developed under govt and private funding and on exploring new technologies for Sanskrit". The learning outcomes add: "The students will get an overview of computational works undertaken in the field of Sanskrit and a clear idea about how a range of practical linguistic tasks of Sanskrit can be done by developing CL systems. And, they will also know how CL tools can facilitate the learning and teaching process in the field of Sanskrit." On May 4, chief minister Rekha Gupta, speaking at the closing ceremony of a 10-day Sanskrit learning initiative, voiced support for the potential the language holds in the field of coding. "Even Nasa scientists have written papers on Sanskrit and confirmed that it is a scientific language. Coding can be done in Sanskrit. It is the most computer-friendly language," she said. Such assertions have sparked renewed discussions on the applicability of Sanskrit in contemporary computing, with DU's course now offering a practical academic framework to explore the language's digital possibilities. The Computational Linguistics Research and Development for Sanskrit initiative at DU's Department of Sanskrit was launched in 2014 under the supervision of Chandra. The group focuses on developing e-learning tools, creating digital content for Sanskrit scientific texts, building language analysis tools, and digitising Sanskrit literature for searchable online access. The department also runs a summer school that invites students from other universities to participate in a programme termed the "emerging intersection of Sanskrit and technology".

Chouhan launches ‘Viksit Krishi Sankalp Abhiyan'
Bhubaneswar: Union minister Shivraj Singh Chouhan on Thursday launched the 'Viksit Krishi Sankalp Abhiyan', a nationwide campaign aimed at transforming Indian agriculture through scientific intervention. The campaign was launched at Sakhigopal in Puri district in the presence of Chief Minister Mohan Charan Majhi, Deputy Chief Minister and Agriculture Minister K V Singh Deo, local MLAs and senior agricultural scientists. Chouhan, the Union Minister of Agriculture and Farmers' Welfare and Rural Development, said the campaign seeks to help India become the 'food basket of the world' by directly connecting agricultural scientists with farmers. The campaign aims to realise Prime Minister Narendra Modi's vision of 'Lab to Land' and the concept of a developed India, he added. Under the initiative, scientists from across the country will leave their laboratories to engage with farmers in over 700 districts, providing hands-on guidance and collecting feedback from the field. 'This is the first time since Independence that such a campaign is being undertaken to connect scientists and farmers directly. The initiative is result-oriented, and under Prime Minister Narendra Modi's government, there will be no shortage of funds for agricultural research,' Chouhan said while addressing the gathering. The campaign will run from May 29 to June 12, aiming to reach and directly engage with around 1.5 crore farmers nationwide. Chouhan encouraged agricultural scientists to view their field visits as a service to the nation's 'Annadatas' (food providers). 'You are going to serve the farmers. It is your good fortune that you are getting a chance to go to the village and talk to the farmers and increase their crop production, there can be no greater virtue than this,' he said. He also appealed to farmers to actively engage with the scientists. 'Please take some time to meet them, learn about new farming techniques, and help increase production. Better seeds mean better yield, and I thank ICAR scientists for developing new seed varieties,' Chouhan added. Highlighting India's agricultural achievements, Chouhan said the country produced 3,539.59 lakh metric tonnes of foodgrains this year—216.61 lakh metric tonnes more than last year. 'India is now capable of feeding its population of 145 crore. But we must not stop — we aim to become the food basket of the world, not just meet our domestic needs but also export to other countries,' he said. Chouhan attributed this success to the blessings of Lord Jagannath, underlining the symbolic importance of launching the campaign from Puri, the holy land of the deity. 'This is not just an agricultural campaign; it's a national mission to ensure our food reserves are full and our farmers' incomes rise,' he told reporters after visiting Jagannath temple to seek blessings before the launch. Before inaugurating the campaign, Chouhan participated in a 'Tiranga Yatra' (Tricolour March) and a plantation programme, alongside Majhi and other dignitaries, marking a symbolic commitment to sustainability and national pride.
