Chennai: Satellite image being used to check Ambattur tank level
'With support from the Indian Space Research Organisation (ISRO), we are getting satellite images that allow us to monitor every 30 metres of the tank's spread area. We are in talks with ISRO to provide clearer images at 1-metre intervals at a reduced cost. Once finalised, the system will be rolled out in all 9,000 tanks across the four districts - Chennai, Tiruvallur, Kancheepuram and Chengalpattu,' an official added.
The WRD is also able to track the water spread area, storage levels and any physical changes in the Ambattur tank automatically, the officials added. Advanced sensor systems have also been installed in Chembarambakkam lake through which the WRD monitors real-time water quality and its data in the portal every 15 minutes. This will facilitate early detection of contamination or degradation for corrective action, officials said.
A drone survey was also carried out to identify silt content in Poondi reservoir, a senior official said.
Developed to create a comprehensive solution for different departments, the platform is built by integrating data of water bodies from the Tamil Nadu e-Governance Agency, Indian Institute of Remote Sensing, Rural Development and Panchayat Raj Department, and so on.

Stunning visuals! Shubhanshu Shukla enjoys view of Earth from ISS
The government of India on Sunday released a set of pictures showing Group Captain Shubhanshu Shukla observing the Earth from the International Space Station. He became the first Indian to be on the station. In the pictures shared online, Shukla is seen seated on the edge of the 7-windowed Cupola Module on the ISS with the Earth visible in the background. 'Gazing Down From The Space! Group Capt Shubhanshu Shukla enjoys the stunning panoramic view of Earth from the 7-windowed Cupola Module aboard the International Space Station. It's been a remarkable journey as he marks a week in orbit, representing India among the stars,' read the caption. Earlier on 26 June, Shukla and three other crew members docked with the ISS following a 28-hour journey around the Earth. As per the details, Shukla is on a 14-day scientific expedition on the ISS as part of the Axiom-4 mission, along with three other astronauts and led by veteran astronaut Peggy Whitson. Shukla is the second Indian to go to space. On Tuesday, Shukla is scheduled to interact with school students at ISRO's North East Space Application Centre (NESAC) from his orbital post on ISS via ham radio. The interaction is planned via a telebridge set up NESAC in Shillong, said the Amateur Radio on International Space Station (ARISS). Earlier on Friday, Shukla interacted with students at the U R Rao Satellite Centre in Bengaluru. On 4 June, Shubhanshu Shukla relished 'aam ras', 'gajar ka halwa', 'moong dal halwa' and delicacies from other countries after he completed a week on board the orbital lab. In a brief interaction with scientists at the URSC, Bengaluru over HAM radio connection, Shukla had said, "It was a good moment. We got food from different countries and got to share it with all the crew."

Indian astronaut Shubhanshu Shukla irrigates seeds in space for future farming
Indian astronaut Shubhandhu Shukla has now completed 10 days in space, advancing research critical to the future of long-duration space work spanned several groundbreaking experiments, each addressing unique challenges of sustaining human life beyond Earth. advertisementOne major focus was the myogenesis investigation, which examines how microgravity accelerates muscle atrophy. In the absence of gravity, astronauts experience rapid weakening of skeletal muscles, a phenomenon linked to molecular and cellular changes. Shux meticulously documented the experiment, which seeks to unravel the precise mechanisms behind muscle loss. The ultimate goal is to develop effective countermeasures to preserve astronaut muscle health during extended missions. Recent studies confirm that microgravity disrupts muscle cell differentiation and metabolism, leading to increased muscle degradation and reduced protein synthesis. Current exercise routines, while helpful, do not fully prevent these declines, underlining the urgency of this another assignment, Shux deployed and later stowed samples for the Space Micro Algae experiment. Microalgae are emerging as promising candidates for sustainable life-support systems in space. Their rapid growth, high photosynthetic efficiency, and resilience make them ideal for producing food, oxygen, and even biofuel in closed habitats. Some species can thrive under extreme space conditions and efficiently recycle carbon dioxide and nutrients, potentially supporting long-term missions and extraterrestrial Indian astronaut also irrigated seeds for the Sprouts project, designed to study how spaceflight affects seed germination and plant development. Insights from this project could transform space agriculture. After the mission, the seeds will be cultivated on Earth over several generations, with researchers analysing genetic, microbial, and nutritional aim is to optimise crop production systems that can reliably supply food for future crews, building on recent successes such as ISRO's rapid cowpea germination in the crew gathered data for the Voyager Displays experiment, which investigates how microgravity affects eye movement and hand-eye coordination—critical factors for designing intuitive spacecraft these experiments represent significant strides toward making deep space travel safer and more sustainable, bringing humanity closer to thriving beyond our home planet.- EndsTune InMust Watch

Finally, India's Gaganyatri Inside Iconic Cupola Of International Space Station
New Delhi: Smiling and beaming, looking healthy and happy, India's own Gaganyatri Group Captain Shubhanshu Shukla looks out of the famous cupola of the International Space Station (ISS). Group Captain Shukla reached the ISS on June 26 on a 14-day mission and is now completing his assigned scientific tasks. He earlier told Prime Minister Narendra Modi he sees no borders from space. Axiom Space says the crew - commander Peggy Whitson, pilot Shubhanshu "Shux" Shukla, and mission specialists Slawosz "Suave" Uznanski-Wisniewski and Tibor Kapu - have now completed nine productive days aboard the ISS. Since their arrival, the crew has been fully dedicated to their packed schedule of scientific research, technology demonstrations, and global outreach. Each day has marked steady progress toward accomplishing mission objectives as the crew contributes to experiments that could shape the future of space exploration and benefit life on Earth. When PM Modi asked about his first thoughts upon seeing space, Group Captain Shukla shared a profound realisation: "From space, you don't see any borders. The Earth looks united." He emphasised the vastness of India, which appears much larger from orbit than on a map, and spoke of the deep sense of unity and shared humanity that space evokes. Incidentally, the Indian Space Research Organisation (ISRO) has not released any photos of Group Captain Shukla in space looking out of the cupola and how he views India from space. On July 3 and 4, Group Captain Shukla had participated in outreach events with schoolchildren in Thiruvananthapuram, Bengaluru and his own alma mater, City Montessori School in Lucknow, where over 500 students had a direct interaction with Group Captain Shukla. But till date the Human Space Flight Center (HSFC) of ISRO has not released any of the videos of the heart-warming interactions he may have had in this space to Earth bridge. A much delayed release by ISRO said "through its student outreach activities aims to stoke curiosity of younger minds in space activities, technology and application." In this context, ISRO has planned outreach activities with the Indian student community on the sidelines of the first mission of ISRO's Gaganyatri to the ISS. These events mark a significant moment in ISRO's efforts on awareness of space activities in the younger generation which will drive them to take up challenging careers in the field of science and technology in future and contribute in realising the vision of Viksit Bharat (developed India)". "Thousands across India and the 1.4 billion population are eagerly waiting to see how Group Captain Shukla mesmerised India's youngsters and ignited the minds of the youth to become future Gaganyatri's. Hopefully the HSFC will release these videos soon. Axiom Space said Group Captain Shukla documented the myogenesis investigation, which explores how the absence of gravity accelerates muscle atrophy. This research examines cellular and molecular mechanisms behind skeletal muscle weakening, with the goal of developing countermeasures to preserve muscle health. In another task, Group Captain Shukla deployed and stowed samples for the Space Micro Algae experiment. These microscopic organisms could potentially serve as sources of food, oxygen, and biofuel in future missions and provide sustainable life support systems in deep space exploration. Group Captain Shukla irrigated crop seeds as part of the 'Sprouts project', an experiment designed to explore how spaceflight affects seed germination and plant growth. Following the mission, the seeds will be cultivated over multiple generations on Earth. Researchers will analyze changes in their genetic makeup, microbial communities, and nutritional content. The goal of the 'Sprouts project' is to advance humanity's understanding of sustainable crop production in space for future long-duration missions. Group Captain Shukla recorded a STEM demonstration to illustrate the differences between physical and chemical changes in microgravity. This hands-on experiment highlighted how the absence of gravity alters familiar processes such as mixing substances, phase transitions, and reactions that produce gases or heat. In his 18-minute interaction with PM Modi, Group Captain Shukla said "Bharat looks bhavya". This brought back a flashback to what Wing Commander Rakesh Sharma said in 1984 about India as being "saare jahan se achha".
