Samudrayaan: NIOT to conduct controlled water trials, crew sphere getting ready
The Matsya-6000 submersible, centerpiece of the Samudrayaan mission, is designed to carry a three-member crew to depths of up to 5,000 meters for deep ocean exploration. Earlier this year, the NIOT successfully completed the maiden harbour wet test at Kattupalli Port near Chennai, which included both manned and unmanned dives to assess the submersible's power, control, flotation, stability, and life support systems.These initial trials validated the core design, but also highlighted areas for improvement, particularly as the mission moves toward deeper and more demanding underwater environments.The upcoming second wet test will focus on the integration and performance of the new titanium exoskeleton, which is expected to enhance the submersible's structural integrity and resilience under extreme pressure.The titanium personnel sphere, being developed in collaboration with Isro, is undergoing advanced welding processes at the Vikram Sarabhai Space Centre, a technological feat given the sphere's 80 mm thickness and the need to withstand pressures found 6,000 meters below sea level.

10 Isro technologies transferred to 6 private firms
PTI file photo BENGALURU: India's space regulator-cum-promoter Indian National Space Promotion and Authorisation Centre ( IN-SPACe ) Thursday said it has facilitated the transfer of ten state-of-the-art technologies developed by Isro to six Indian industries across the upstream, midstream, and downstream segments. In the upstream segment, two advanced inertial sensors — the Laser Gyroscope and Ceramic Servo Accelerometer — developed by Isro's Inertial Systems Unit have been transferred to Zetatek Technologies. For the midstream segment, three technologies related to ground station operations were transferred. 'These include: the S/X/Ka tri-band dual circular polarised monopulse feed, a tri-axis antenna control servo system, and the Ku/C/L and S Band Cassegrain feed. All developed by Isro, these were transferred to Avantel and Jisnu Communications, both Hyderabad-based firms specialising in communications solutions for space and defence,' IN-SPACe said. It added that these technologies will contribute to self-reliant development of critical ground station infrastructure. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo In the downstream domain, two geospatial technologies — pest forewarning and semi-physical crop yield estimation models developed by Isro's Space Applications Centre — were handed over to Amnex Info Technologies, Ahmedabad. These models will support agricultural decision-making and crop protection. 'A compact, multi-parameter portable bathymetry system developed by Isro's National Remote Sensing Centre (NRSC) was transferred to Jalkruti Water Solutions, Ahmedabad, for UAV-based water resource monitoring. Additionally, Vikram Sarabhai Space Centre's ceramic-based flame-proof coating, originally developed for launch vehicles, was acquired by Ramdev Chemicals, also in Ahmedabad, for broader industrial use. All transfers were formalised through tripartite Technology Transfer Agreements (TTAs) signed between NewSpace India Limited (NSIL), the respective recipient firms, and IN-SPACe. IN-SPACe chairman Pawan Goenka said the move was a significant step in enabling private sector growth . 'Isro has a flourishing repository of R&D in space technologies and it is time we leverage that to the optimum to strengthen India's space industrial ecosystem. Industry-led innovation will play a key role,' he added. Rajeev Jyoti, director-technical, IN-SPACe, added that these technologies, previously imported, are now being indigenised.

Axiom-4 one small step in orbit, giant leap for spaceflight & discovery: Isro
BENGALURU: Several days after India's Group Captain Shubhanshu Shukla entered the International Space Station (ISS), , stating that 'space is a domain best explored together,' said its participation in the Axiom-04 mission echoes that spirit. Tired of too many ads? go ad free now Axiom-4 follows in the legacy of international cooperation that sent Rakesh Sharma to space in 1984 aboard the Soviet Soyuz, Isro said, and added: '...This is one small step in orbit, but a giant leap in India's pursuit of human spaceflight and scientific discovery.' The space agency said: '...The professionalism, dedication, and scientific excellence demonstrated by all partner agencies in the lead-up to the Axiom-4 mission have been truly inspiring. Isro is deeply appreciative of the partnership and camaraderie shown by our counterparts around the world.' Reiterating that the mission was conceptualised during PM Narendra Modi's visit to the US in 2023, Isro said the PM's leadership continues to shape India's future in space as one that is collaborative, confident, and committed to peaceful exploration. Ax-4 is expected to provide useful operational inputs for Isro's , particularly in areas such as astronaut health telemetry, crew-ground coordination, multi-agency integration, and experiment execution in space conditions. 'These insights will directly influence mission planning, safety validation, and astronaut readiness for India's first indigenous human spaceflight mission,' Isro said. Onboard the ISS, a set of Indian scientific experiments is being conducted as part of the Ax-04 mission. These cover life sciences, fluid dynamics, health monitoring, and Earth observation. 'Redwire Space, US, is coordinating the payload integration activities. Tired of too many ads? go ad free now Redwire facilitated key steps, including technical validation and compliance with ISS payload requirements. Each experiment is packaged into flight-ready payload containers. Redwire is also supporting the development of hardware handling protocols, ensuring that the Indian experiments could be safely deployed and operated onboard ISS, thereby enabling meaningful scientific outcomes for India's research community,' Isro said. Pointing out how the launch was rescheduled multiple times due to issues such as a harness problem in Dragon, weather in the ascent corridor, leakage in the Falcon-9 booster stage, and leakage in the Zvezda Module of the ISS, the space agency said: 'The Isro delegation played a constructive role in resolving all the issues. It made its stand clear that all problems should be resolved before clearing the launch for lift-off, considering the mission risks and safety of the crew. ' The Indian astronauts —Shukla and his backup Group Captain Prashanth B Nair — have trained in spacecraft systems, microgravity operations, emergency protocols, space medicine, and experiment handling. As part of the programme, he also participated in Nasa's National Outdoor Leadership Programme (NOLPS) in the Mexican wilderness, designed to build team resilience and psychological readiness.
