'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.

Pune scientist leads global team helping ALS patients regain voice
PUNE A Pune-based scientist is front and centre of a major milestone in neurotechnology – an implant-based brain-computer interface (BCI) that enables an individual with advanced amyotrophic lateral sclerosis (ALS) to speak in real time with natural intonation, and even sing. Pune-based scientist is part of neurotech project team that enables individual with advanced amyotrophic lateral sclerosis (ALS) to speak in real time with natural intonation, and even sing. (HT) Dr Maitreyee Wairagkar – a former student of Jnana Prabodhini (Nigdi) and Fergusson College who completed her Engineering Masters and Ph.D. from the United Kingdom and is now based at UC Davis as 'project scientist' to lead the project since the last three years – has set an example of what Indian girls can achieve provided they get a chance. Dr Wairagkar – working with her team of researchers at UC Davis's Neuroprosthetics Laboratory since the last three years – has led the project from conception to design to execution and developed this 'first-in-world' technology that demonstrates a brain-to-voice neuroprosthesis capable of synthesising speech with less than a 25-millisecond delay, virtually indistinguishable from natural vocal feedback. Dr Wairagkar is the first author on the study published in the scientific journal, 'Nature' on June 12, 2025. Drawing on Dr Wairagkar's expertise, her team has developed algorithms to extract and denoise neural features, train phoneme and pitch decoders, and craft a full end-to-end voice synthesis system. Dr Wairagkar and team have enabled the decoding of fine-grained paralinguistic cues, allowing the user to express not just words but also emotion and melody. The system uses 256 microscale electrodes implanted in the ventral precentral gyrus, which is the part of the brain crucial for speech production. In the course of the study, as the participant attempted to speak, neural signals were decoded in real time into phonemes and paralinguistic features like pitch and emphasis and subsequently transformed into audible speech through a vocoder and speaker system. Importantly, the participant was not only able to communicate new words but also ask questions, shift intonation, and sing simple melodies in a major leap towards expressive, spontaneous communication. About the achievement, Dr Wairagkar said, 'What makes this technology extraordinary is not just that it translates brain activity into speech, but that it does so with the flow and character of natural voice. That expressiveness is what makes real conversation possible, and human.' Dr Wairagkar's contributions allowed the participant to control tone and stress in real time; a feature absent in earlier BCIs that often relied on slow, word-by-word output. Senior researchers at UC Davis, including Dr Sergey Stavisky and neurosurgeon Dr David Brandman, emphasised the emotional and practical impact of the work. 'This is the first time we have been able to restore a participant's own voice in real time, allowing him not only to talk but to sound like himself,' said Dr Stavisky. Dr Brandman—who implanted the arrays under the BrainGate2 clinical trial—highlighted the emotional power of restoring not just speech, but the participant's own voice. Test listeners recognised nearly 60% of the words correctly when BCI-driven voice was used (compared to just 4% intelligibility in natural, dysarthric speech), underscoring dramatic improvements in communication clarity. The neuroprosthesis not only decodes speech at the phoneme level but also captures prosody—how a sentence is said—making it the closest attempt yet at recreating natural, flowing conversation from thought alone. This milestone represents a profound shift in assistive communication for people living with ALS, brainstem strokes, or other forms of locked-in syndrome. It also puts India at the centre of a transformative global scientific collaboration through Dr Wairagkar's involvement. The researchers note that although the findings are promising, brain-to-voice neuroprostheses remain in an early phase. A key limitation is that the research was performed with a single participant with ALS. It will be crucial to replicate these results with more participants, including those who have speech loss from other causes such as stroke. As further trials progress and the technology is refined, experts believe this innovation could redefine how neurotechnology restores voice and identity for millions who are otherwise left voiceless.

Axiom-4 put off again, ISRO decides to recall Group Captains Shukla, Nair
BENGALURU: Two days before the scheduled launch of the much-awaited Axiom-4 (Ax-4) Space Mission on June 22, Axiom Space on Friday announced its indefinite postponement. Axiom Space, which is spearheading the 14-day Ax-4 Space Mission to the International Space Station (ISS) with four astronauts from the US, India, Poland and Hungary, has not given the next launch date. Following this, the Indian Space Research Organisation decided to recall Ax-4 mission pilot Group Captain Shubhanshu Shukla and reserve crew member Group Captain Prasanth Balakrishnan Nair. 'NASA has made the decision to stand down from a launch on Sunday, June 22, and will target a new launch date in the coming days. The space agency (NASA) needs additional time to continue evaluating International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory's Zvezda service module. Because of the space station's interconnected and interdependent systems, NASA wants to ensure the station is ready for additional crew members, and the agency is taking the time necessary to review the data,' an Axiom Space statement read. The $64 million space mission is a multi-agency collaboration, involving Axiom Space, ISRO, NASA and European Space Agency (ESA). 'The (Indian) astronauts will be returning. There are many technical issues that need to be addressed before the mission is launched,' said a senior ISRO scientist. Shukla and Nair are among the four Indian astronauts selected for India's first manned space mission, Gaganyaan, scheduled to be launched some time in 2027. ISRO Chairman V Narayanan said the Ax-4 mission delays will have no impact on the Gaganyaan mission, which, he said, is progressing as per schedule.
