Astronaut Shubhanshu Shukla To Talk To Students, ISRO Engineers Via Radio
Astronaut Shubhanshu Shukla is set to interact with school students and scientists at the Indian Space Research Organisation (ISRO) from his orbital post on the International Space Station via ham radio on Friday evening.
The interaction is planned via a telebridge set up at the U R Rao Satellite Centre in Bengaluru, said the Amateur Radio on International Space Station (ARISS), which facilitates interaction of school students with astronauts on the orbital laboratory.
Group Captain Shukla is on a 14-day scientific expedition on the International Space Station (ISS) as part of the Axiom-4 mission, along with three other astronauts.
The ARISS programme inspires students worldwide to pursue interests and careers in science, technology, engineering and mathematics through amateur radio-communication opportunities with the ISS on-orbit crew.
"Contact upcoming with India! @Axiom_Space #Ax4 crew member Shubhanshu Shukla, VU2TNI, will talk to the UR Rao Satellite Centre (URSC) in Karnataka via ham radio from the Space Station. Scheduled Fri. July 4 at 10:17 UTC, 6:17 AM ET, 3:47 PM ISS via K6DUE telebridge," the ARISS said in a post on X.
Ham radio, officially known as amateur radio, is a non-commercial radio-communication service operated by licensed enthusiasts and is considered a reliable mode of communication during disasters, when conventional modes of communication are not available.
Meanwhile, Group Captain Shukla was busy conducting the space microalgae experiment on Sunday.
He deployed sample bags and captured images of the algae strains in his orbital post on the ISS.
"These tiny organisms could play a big role in the future of space exploration, offering a sustainable, nutrient-rich food source for long-duration missions," Axiom Space said.
The Axiom-4 crew also collected data for the Neuro Motion VR project, where astronauts don VR headsets and perform attention-based tasks, while their brain activity is monitored using functional near-infrared spectroscopy (fNIRS).
"This research explores how microgravity affects cognitive and motor functions, which could provide valuable insight for future deep-space missions," Axiom Space said.
Data was also gathered for the Telemetric Health AI study, which integrates biometric data with mission analytics to better understand how spaceflight impacts cardiovascular and balance systems.
By applying advanced data-science techniques, the project could lead to smarter, real-time health monitoring -- both on orbit and on Earth.

Inside Meta's Superintelligence Lab: The scientists Mark Zuckerberg handpicked; the race to build real AGI
Mark Zuckerberg has rarely been accused of thinking small. After attempting to redefine the internet through the metaverse, he's now set his sights on a more ambitious frontier: superintelligence—the idea that machines can one day match, or even surpass, the general intelligence of humans. To that end, Meta has created an elite unit with a name that sounds like it belongs in a sci-fi script: Meta Superintelligence Lab (MSL). But this isn't fiction. It's a real-world, founder-led moonshot, powered by aggressive hiring, audacious capital, and a cast of technologists who've quietly shaped today's AI landscape. This is not just a story of algorithms and GPUs. It's about power, persuasion, and the elite brains Zuckerberg believes will push Meta into the next epoch of intelligence. The architects: Who's running Meta's AGI Ambitions? Zuckerberg has never been one to let bureaucracy slow him down. So he didn't delegate the hiring for MSL—he did it himself. The three minds now driving this initiative are not traditional corporate executives. They are product-obsessed builders, technologists who operate with startup urgency and almost missionary belief in Artificial general intelligence (AGI). Name Role at MSL Past Lives Education Alexandr Wang Chief AI Officer, Head of MSL Founder, Scale AI MIT dropout (Computer Science) Nat Friedman Co-lead, Product & Applied AI CEO, GitHub; Microsoft executive B.S. Computer Science & Math, MIT Daniel Gross (Joining soon, role TBD) Co-founder, Safe Superintelligence; ex-Apple, YC No degree; accepted into Y Combinator at 18 Wang, once dubbed the world's youngest self-made billionaire, is a data infrastructure prodigy who understands what it takes to feed modern AI. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like My baby is in so much pain, please help us? Donate For Health Donate Now Undo Friedman, a revered figure in the open-source community, knows how to productise deep tech. And Gross, who reportedly shares Zuckerberg's intensity, brings a perspective grounded in AI alignment and risk. Together, they form a high-agency, no-nonsense leadership core—Zuckerberg's version of a Manhattan Project trio. The Scientists: 11 defections that shook the AI world If leadership provides the vision, the next 11 are the ones expected to engineer it. In a hiring spree that rattled OpenAI, DeepMind, and Anthropic, Meta recruited some of the world's most sought-after researchers—those who helped build GPT-4, Gemini, and several of the most important multimodal models of the decade. Name Recruited From Expertise Education Jack Rae DeepMind LLMs, long-term memory in AI CMU, UCL Pei Sun DeepMind Structured reasoning (Gemini project) Tsinghua, CMU Trapit Bansal OpenAI Chain-of-thought prompting, model alignment IIT Kanpur, UMass Amherst Shengjia Zhao OpenAI Alignment, co-creator of ChatGPT, GPT-4 Tsinghua, Stanford Ji Lin OpenAI Model optimization, GPT-4 scaling Tsinghua, MIT Shuchao Bi OpenAI Speech-text integration Zhejiang, UC Berkeley Jiahui Yu OpenAI/Google Gemini vision, GPT-4 multimodal USTC, UIUC Hongyu Ren OpenAI Robustness and safety in LLMs Peking Univ., Stanford Huiwen Chang Google Muse, MaskIT – next-gen image generation Tsinghua, Princeton Johan Schalkwyk Sesame AI/Google Voice AI, led Google's voice search efforts Univ. of Pretoria Joel Pobar Anthropic/Meta Infrastructure, PyTorch optimization QUT (Australia) This roster isn't just impressive on paper—it's a coup. Several were responsible for core components of GPT-4's reasoning, efficiency, and voice capabilities. Others led image generation innovations like Muse or built memory modules crucial for scaling up AI's attention spans. Meta's hires reflect a global brain gain: most completed their undergrad education in China or India, and pursued PhDs in the US or UK. It's a clear signal to students—brilliance isn't constrained by geography. What Meta offered: Money, mission, and total autonomy Convincing this calibre of talent to switch sides wasn't easy. Meta offered more than mission—it offered unprecedented compensation. • Some were offered up to $300 million over four years. • Sign-on bonuses of $50–100 million were on the table for top OpenAI researchers. • The first year's payout alone reportedly crossed $100 million for certain hires. This level of compensation places them above most Fortune 500 CEOs—not for running a company, but for building the future. It's also part of a broader message: Zuckerberg is willing to spend aggressively to win this race. OpenAI's Sam Altman called it "distasteful." Others at Anthropic and DeepMind described the talent raid as 'alarming.' Meta, meanwhile, has made no apologies. In the words of one insider: 'This is the team that gets to skip the red tape. They sit near Mark. They move faster than anyone else at Meta.' The AGI problem: Bigger than just scaling up But even with all the talent and capital in the world, AGI remains the toughest problem in computer science. The goal isn't to make better chatbots or faster image generators. It's to build machines that can reason, plan, and learn like humans. Why is that so hard? • Generalisation: Today's models excel at pattern recognition, not abstract reasoning. They still lack true understanding. • Lack of theory: There is no grand unified theory of intelligence. Researchers are working without a blueprint. • Massive compute: AGI may require an order of magnitude more compute than even GPT-4 or Gemini. • Safety and alignment: Powerful models can behave in unexpected, even dangerous ways. Getting them to want what humans want remains an unsolved puzzle. To solve these, Meta isn't just scaling up—it's betting on new architectures, new training methods, and new safety frameworks. It's also why several of its new hires have deep expertise in AI alignment and multimodal reasoning. What this means for students aiming their future in AI This story isn't just about Meta. It's about the direction AI is heading—and what it takes to get to the frontier. If you're a student in India wondering how to break into this world, take notes: • Strong math and computer science foundations matter. Most researchers began with robust undergrad training before diving into AI. • Multimodality, alignment, and efficiency are key emerging areas. Learn to work across language, vision, and reasoning. • Internships, open-source contributions, and research papers still open doors faster than flashy resumes. • And above all, remember: AI is as much about values as it is about logic. The future won't just be built by engineers—it'll be shaped by ethicists, philosophers, and policy thinkers too. Is your child ready for the careers of tomorrow?

Muscles, Microbes, And Microgravity: India's First Biology Experiments In Space
New Delhi: India has taken its first bold steps into space biology with a series of pioneering experiments aboard the International Space Station (ISS), as part of the Axiom-4 mission-referred to by some as Mission Akash Ganga. These experiments, conducted by Group Captain Shubhanshu Shukla, mark a significant milestone in India's scientific and technological journey, exploring how biological systems behave in microgravity and radiation-rich environments. At the heart of this initiative is the Department of Biotechnology (DBT), under the leadership of Dr Rajesh Gokhale, Secretary of DBT. In an exclusive conversation with NDTV, Dr Gokhale described the mission as a "floating lab in space" that will help India understand biological adaptability in ways never tested before. The experiments are designed to explore fundamental questions about human health, sustainability, and bio-manufacturing in space. Muscle Stem Cell Regeneration In Microgravity One of the flagship experiments led by DBT focuses on skeletal muscle stem cells. Conducted by the Institute for Stem Cell Science and Regenerative Medicine (InStem) in Bengaluru, this study investigates how microgravity affects the regeneration of muscle tissue. In space, the absence of gravitational force leads to muscle and bone mass reduction, a phenomenon well-documented in astronauts. Dr Gokhale explained that the experiment will compare muscle stem cell behaviour in space with those grown under Earth conditions. The goal is to understand whether the regenerative capacity of these cells is compromised in microgravity. This research could have far-reaching implications - not only for astronaut health during long-duration missions but also for treating age-related muscle degeneration and diseases like muscular dystrophy on Earth. The experiment explores the role of mitochondria - the powerhouse of the cell - in maintaining muscle health. Mitochondrial dysfunction is a known contributor to muscle loss. DBT scientists are testing two compounds: dihydrofolate and a thiol-containing amino acid, both known to enhance mitochondrial function. By supplementing these chemicals in space-grown muscle cells, researchers aim to determine whether mitochondrial regeneration can be achieved in microgravity. If successful, this could lead to new therapeutic strategies for muscle recovery in space and on Earth, particularly for conditions like sarcopenia and cachexia. Edible Microalgae Cultivation One DBT-led experiment involves growing edible microalgae in space. Conducted by the International Centre for Genetic Engineering and Biotechnology (ICGEB) in Delhi, this study examines how three species of microalgae adapt to space conditions. These algae are photosynthetic organisms that absorb carbon dioxide and release oxygen - making them ideal candidates for life support systems in space. Dr Gokhale emphasised the dual benefits of this experiment: oxygen generation and food production. Microalgae could serve as bio-regenerators in future missions like Gaganyaan, replacing traditional chemical-based systems like zeolites. Their ability to grow continuously and be consumed makes them a sustainable solution for long-term space habitation. Cyanobacteria For Nutrient Recycling Another innovative experiment focuses on cyanobacteria, known for their ability to recycle nutrients. Human urine, rich in urea and nitrogen, presents a challenge in closed-loop space environments. This study investigates how cyanobacteria assimilate nitrogen from both organic (urea) and inorganic (nitrate) sources. The aim is to convert waste into usable resources-a concept Dr Gokhale described as "waste to wealth in space". Understanding how these bacteria function in microgravity could lead to efficient nutrient recycling systems for future space stations and planetary habitats. Seed Sprouting And Crop Growth India is also conducting experiments on seed sprouting, involving crops like fenugreek (methi) and moong or green gram. These seeds are being grown in space to observe changes in growth patterns and microbial interactions. Although the sprouted seeds will not be consumed by Mr Shukla, they will be returned to Earth for detailed analysis. This experiment is part of a broader effort to understand how Indian crop varieties respond to space conditions. It could pave the way for space farming and food security in extra-terrestrial environments. Eye Function And Screen Exposure While not directly under DBT, another experiment examines how prolonged exposure to screens affects eye function in space. Vision problems have been reported among astronauts, and this study aims to understand the physiological changes that occur in microgravity. It adds a critical dimension to astronaut health research. Water Bears (Tardigrades) Reproduction A particularly intriguing experiment involves tardigrades, microscopic organisms known for their resilience. Researchers are studying their reproductive cycle in space, specifically whether they can lay and hatch eggs under microgravity conditions. This could offer insights into how complex biological processes like reproduction are affected by space environments. Seeds For Genetic Analysis India is also sending seeds of various crop varieties to space, not for growth but for genetic analysis upon return. This experiment, though previously conducted by other nations, carries an Indian signature and aims to understand how space exposure affects genetic traits. Implications For Bio-Manufacturing And Policy These experiments align with India's Bio-E3 policy - Biotechnology for Economy, Environment, and Employment - approved by the Cabinet and championed by Prime Minister Narendra Modi. Dr Gokhale highlighted that DBT's collaboration with ISRO is part of a long-term roadmap extending to 2040. The insights gained from these studies could revolutionise bio-manufacturing, especially in areas like carbon dioxide fixation and metabolic engineering. For example, algae used in space could be adapted to trap industrial emissions on Earth, offering sustainable solutions to climate challenges. A Vision For Viksit Bharat Dr Gokhale emphasised the transformative potential of cross-disciplinary science. From sports medicine to space biology, DBT is expanding its horizons to contribute to Viksit Bharat - a developed India. The department's pioneering role in biotechnology, from GM mustard to COVID vaccines, now extends to the final frontier, space. As India steps into the realm of space biology, these "baby steps" could soon become giant leaps, shaping the future of human health, sustainability, and innovation both in orbit and on Earth. India has big ambitions in space, from launching an Indian to space in 2027, having a space station by 2035 and landing an Indian on the moon by 2040. Group Captain Shukla has in fact laid the first firm footsteps for India's ambitious human space flight mission.

Meet the toys that have floated in space: From Joy to Buzz Lightyear
Space missions involve high-tech equipment and elaborate science; however, many astronauts also travel with soft toys. Shubhanshu Shukla carried Joy with him on the Axiom-4 NASA project. Joy is a white baby swan soft toy, and along with being an adorable companion, Joy serves as a zero-gravity indicator and carries significant cultural was chosen by Shukla's six-year-old son to accompany them on the spacecraft. Once in orbit, Joy becomes "weightless," serving as a clear visual cue that the crew is in this, Joy symbolises wisdom and purity in Indian culture, loyalty in Poland, and grace in Hungary, reflecting the crew's diverse backgrounds. Shukla highlighted that Joy serves as a meaningful companion, helping the team focus on what truly matters during their mission in space. When people think of space missions, they think in terms of complex machines, satellites, and scientific experiments. However, behind the scenes, astronauts sometimes take toys with them to help them remember home, inspire inquisitive children watching from Earth, and sometimes help to demonstrate science concepts. Either towards the end of a school year, many of the toys have not only been fun, but have also had realistic the years, many toys, from characters popularised in memorable movies to handmade stuffed animals, have floated inside the International Space Station (ISS). Each toy has a story to tell and a reason to be in are the most interesting toys for travelling in Yoda joined the crewIn 2020, during SpaceX's Crew-1 mission, a Baby Yoda toy from The Mandalorian series joined NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japanese astronaut Soichi Noguchi on their journey to the ISS. Astronaut Victor Glover playfully told mission control, 'Baby Yoda says you guys can come back on board,' after the cameras had briefly turned off, making the toy an instant hit on social media.
