The Defence Research and Development Organisation (DRDO) has started work on an advanced program to develop in-orbit robotics for space applications. The project is being led by scientist Kiran Akella and aims to complete its first operational phase by 2027. This initiative is seen as a major step in strengthening India’s indigenous capabilities in robotics, artificial intelligence, and aerospace engineering.   The project will design legged robotic systems that can operate in zero-gravity and low-gravity environments. Unlike conventional robotic arms, these robots will have mobility to move across spacecraft surfaces and carry out complex activities. They will be capable of performing tasks such as inspection, maintenance, assembly, refuelling, and even repair work in orbit. This would reduce the need for human spacewalks and improve the sustainability of long-duration missions.   One of the key objectives is to support India’s growing presence in space and to align with the vision of Atmanirbhar Bharat. The robots will have multiple uses including satellite servicing, orbital debris removal, on-orbit assembly of large structures like the proposed Bharatiya Antariksh Station, and inspection of spacecraft to ensure safety and reliability.   DRDO’s technical work in this area will cover advanced fields such as pose estimation through vision and AI-based systems, autonomous operations with minimal human control, and sensing technologies that combine data from multiple inputs for accurate navigation and task execution. The robots will be built using lightweight and radiation-resistant materials to ensure they can function effectively during long missions in space.   Although the initial focus is on space, the technology also has clear defence applications. Legged robots can be adapted for use in challenging terrains on Earth, including high-altitude regions, caves, and tunnels where wheeled or tracked vehicles face limitations. Such robots could assist the Indian Armed Forces in reconnaissance, logistics, and engineering operations in hazardous environments.   Globally, organisations like NASA and the European Space Agency have already advanced in robotic systems for orbital work. India’s approach, however, is unique in focusing on legged robotics, which offer more flexibility than traditional designs. This development could also open the door for future collaborations with countries such as France and Japan, both of which are active in robotic servicing research.   By 2027, DRDO expects to demonstrate the first phase of this capability, including robotic satellite docking, orbital debris management, and early construction of modular structures in orbit. These systems could later be integrated with ISRO missions, including future stages of Gaganyaan, lunar exploration projects, and deep-space missions. For the defence sector, ruggedised versions of these robots could be introduced by the end of the decade to strengthen battlefield support and logistics in difficult conditions.   The success of this program would provide India with independent capability in a field where only a few nations have progressed, ensuring both civilian and military benefits from the same line of technological development.

NASA’s Interstellar Mapping and Acceleration Probe (IMAP) is scheduled to launch on 24 September 2025, marking a major step forward in our understanding of the heliosphere—the giant bubble of particles and magnetic fields created by the Sun that surrounds our solar system. Equipped with precision thrusters from L3Harris, the spacecraft will travel to Lagrange Point 1 (L1), located about 1.5 million kilometers from Earth. From this vantage point, IMAP will study the solar wind and its complex interaction with interstellar material, helping scientists learn more about how particles move between the Sun and the galaxy beyond.   Advanced Propulsion from L3Harris The propulsion system, designed and integrated at L3Harris’ Redmond, Washington facility, is essential for IMAP’s journey and operations. It includes: Three propellant tanks Service and latch valves Filters and transducers Temperature sensors and heaters 12 MR-111G monopropellant rocket engines These thrusters will provide attitude control, orbit insertion, spin adjustments, and corrective maneuvers throughout the mission. “Our thrusters enable IMAP’s attitude control system to steer the spacecraft, perform orbit insertion, adjust its spin rate and perform corrective maneuvers as needed to maintain its orbit,” explained Chris Sebastian, lead program engineer at L3Harris.   Scientific Goals of IMAP IMAP carries 10 scientific instruments to investigate: How solar particles are accelerated to high energies How the solar wind interacts with interstellar space The processes at the boundary of the heliosphere, where the influence of the Sun gives way to the galactic environment The mission is led by Professor David J. McComas of Princeton University, with more than 27 partner institutions worldwide contributing. The Johns Hopkins Applied Physics Laboratory (APL) is responsible for building and operating the spacecraft under NASA’s Heliophysics Division.   Broader Significance The IMAP mission builds on the legacy of past heliophysics missions such as Voyager, IBEX (Interstellar Boundary Explorer), and Parker Solar Probe. While Voyager provided the first direct data from beyond the heliosphere, and IBEX mapped energetic neutral atoms from its boundary, IMAP will combine advanced instruments and high-resolution imaging to fill critical gaps in our knowledge. By answering key questions about space radiation, cosmic rays, and the shielding role of the heliosphere, IMAP’s data will not only enhance our scientific understanding but also provide insights important for future deep-space exploration and astronaut safety. As Matt Carollo of L3Harris put it: “Knowing that the propulsion system our team designed, built and installed on the IMAP spacecraft will enable researchers to expand our knowledge of our galactic neighborhood is very rewarding.”

India is preparing to take a major leap in space security with the development of “bodyguard satellites”—special spacecraft designed to protect the nation’s critical satellites from threats in orbit. These protective companions will not perform communication or imaging tasks, but instead will act as guards in space, monitoring and defending valuable assets against collisions, interference, or hostile actions.   Why Bodyguard Satellites Are Needed In 2024, an Indian satellite had a close call when a foreign spacecraft came dangerously near—within just 1 kilometre. Although there was no collision, the incident highlighted how vulnerable India’s space infrastructure is. With the increasing number of satellites in orbit and the growing competition among nations, the need for active protection has become urgent. India relies heavily on satellites for communication, navigation (NavIC), weather forecasting, military surveillance, and disaster management. Any disruption or damage could paralyze vital services on the ground, making it clear why a dedicated protection system is essential.   How Bodyguard Satellites Work A bodyguard satellite will orbit close to a high-value satellite, constantly scanning the surrounding space. Using sensors, cameras, radars, and infrared detectors, it can spot approaching objects—whether space debris or a suspicious foreign satellite. Possible functions may include: Surveillance & detection – keeping watch on nearby space activity. Tracking & identification – distinguishing between harmless debris and potential threats. Early warning – alerting ground stations and the protected satellite about approaching dangers. Defensive action – maneuvering to block or distract a hostile satellite, or helping its companion move away from danger. The biggest challenge lies in precision maneuvering. The bodyguard must stay close enough to react quickly but not so close that it risks collision itself.   India’s Larger Space Security Vision The bodyguard satellites are expected to be part of a broader multi-layer defense system. India is already running programs like Project NETRA, which tracks space debris, and IS4OM, which manages safe satellite operations. Alongside these, India plans to build a network of nearly 50 surveillance satellites to watch over its orbital assets. This plan could involve an investment of more than ₹27,000 crore, reflecting the government’s recognition that space is no longer just for science—it is a strategic battlefield where power and security go hand in hand. Developing and operating bodyguard satellites will not be easy. India will need to overcome: Collision risks during close-proximity operations. Accurate sensors to avoid false alarms. Fuel and energy limits, since maneuvering in orbit consumes significant resources. International laws, because active space defense may raise diplomatic questions. Still, the importance of protecting satellites outweighs these hurdles.   A Step Toward Resilient Space Power The creation of bodyguard satellites would place India among the few nations capable of active satellite defense. It strengthens deterrence, ensuring that any adversary will think twice before attempting to interfere with India’s orbital assets. As the global race for space dominance intensifies, India’s move signals its determination to safeguard its satellites—the invisible backbone of modern life. With this bold step, the country is transforming from being just a spacefaring nation to becoming a space-secure nation.

A Russian biological research satellite, Bion-M No. 2, has successfully returned to Earth after spending 30 days in orbit. The spacecraft, often called a “Noah’s Ark” because of the wide variety of life it carried, landed on September 19 in the Orenburg region steppes. It was launched on August 20 aboard a Soyuz-2.1b rocket from the Baikonur Cosmodrome.   The Mini-Ark in Orbit Bion-M No. 2 carried a rich collection of living specimens and scientific experiments, including: 75 mice, specially selected to test sensitivity to space radiation. More than 1,500 fruit flies, ideal for studying nervous system health and reproduction. Plant seeds from various species to explore how they respond to cosmic radiation. Microorganisms and cell cultures to see how space affects tiny life forms. Samples embedded in rocks, part of an experiment called “Meteorite” to test whether microbes could survive the intense heat of reentry — supporting or challenging the theory of panspermia, the idea that life may have come to Earth from space. The spacecraft orbited at an altitude of 370 to 380 kilometers, at an inclination of about 97 degrees, exposing its passengers to higher levels of cosmic radiation than astronauts usually face on the International Space Station.   The Landing and First Examinations When the capsule touched down, a small brush fire broke out near the site but was quickly extinguished. Recovery teams, supported by helicopters, rushed to retrieve the capsule and began immediate checks on the animals. Out of the 75 mice, 65 survived. Experts explained that the loss of 10 mice was mostly due to intra-group aggression among the males rather than purely the effects of space conditions. Scientists on-site examined the fruit flies, checking their motor activity to identify any nervous system problems. A medical tent was set up at the landing site for initial tests. Later, the biological samples were transported to the Institute of Biomedical Problems in Moscow for detailed laboratory studies.   What Scientists Want to Learn The mission included over 30 experiments, divided into 10 main research sections: Studying gravitational physiology in animals to improve life support technologies for astronauts. Understanding how plants, microbes, and their communities adapt to space conditions. Conducting biotechnological and technical experiments for future spacecraft systems. Performing radiobiological and dosimetric experiments to improve astronaut radiation safety. Involving students from Russia and Belarus with experiments designed for education and training.   Why This Matters The Bion-M No. 2 mission is more than just a biological flight — it’s a crucial step in preparing for long-duration human missions to the Moon and Mars. Key insights include: How radiation and weightlessness together affect living beings. The genetic factors that make some organisms more resilient or vulnerable. How seeds and plants cope with space conditions, supporting the idea of space farming. Whether microbes can survive extreme conditions, linking to theories of life spreading across the universe.   Despite some challenges, including the death of a few mice, the mission was largely successful. The data collected will help scientists design safer spacecraft, radiation protection methods, and sustainable habitats for astronauts. In many ways, Bion-M No. 2 shows us that life — in all its forms — can endure beyond Earth. It is a reminder that every step we take in space brings us closer to understanding both our future in the cosmos and the very origins of life itself.

India : At the National Workshop on Hydrogen Fuel Technologies in Bengaluru, ISRO Chairman Dr. V. Narayanan emphasized that hydrogen will play a transformative role in shaping India’s space missions, clean energy transition, and industrial ecosystem. His speech served both as a progress report and a roadmap for how hydrogen could become the backbone of India’s technological independence.   Key Highlights of ISRO’s Work Cryogenic Propulsion Mastery: India now possesses full control over liquid hydrogen–oxygen cryogenic engines, a capability once denied. The LVM-III rocket, marking India’s 100th successful launch in January 2025, used this advanced technology. Fuel Cells in Space: A 100-watt oxygen-hydrogen fuel cell was tested in orbit, and ISRO is developing a 20-kilowatt system for sustained power in long missions. This paves the way for the Bhartiya Antariksh Station and future deep space exploration. Human Moon Mission: ISRO is working on a hydrogen-fueled upper stage rocket with 60–70 tons capacity for India’s first crewed lunar mission by 2040. Industrial Applications: Beyond rockets, ISRO and Tata Motors pioneered a hydrogen fuel cell bus, and in June 2025, five such buses entered commercial service. Public enterprises like BHEL and NTPC are now scaling hydrogen turbines and transport systems.   Why Hydrogen Matters Hydrogen represents more than just a new fuel source. For India, it symbolizes strategic autonomy and climate responsibility. With rising global concern over fossil fuels and carbon emissions, hydrogen offers a clean, abundant, and adaptable energy solution. In space, hydrogen enables long-duration human missions, something vital if India aims to establish a permanent human presence on the Moon or build an Indian space station. Unlike conventional fuels, hydrogen can also be regenerated from renewable energy sources, closing the loop between Earth-based sustainability and space exploration. At the industrial level, hydrogen could be the missing link that bridges India’s growth with its environmental commitments. Heavy industries, transport, and power plants—often accused of being polluting—could transition to hydrogen and drastically reduce their carbon footprint. However, challenges remain. Storage and safety are critical, as hydrogen is highly flammable and difficult to contain. This is why ISRO’s focus on millisecond-response hydrogen leak sensors is not just technical but existential. Any large-scale adoption of hydrogen depends on ensuring public confidence in its safety.   Future Outlook Looking ahead, India’s hydrogen journey will not be limited to rockets and buses. The National Green Hydrogen Mission seeks to position India as a global hub for hydrogen production, consumption, and exports. This could reshape India’s role in the international energy economy, reducing dependence on imported oil and gas while opening new export markets. For young scientists and engineers, Dr. Narayanan’s call was clear: hydrogen is the frontier where energy, environment, and exploration converge. By mastering it, India can not only achieve energy independence but also secure its place as a leader in the 21st-century hydrogen revolution.

This handover underscores LPSC’s enduring commitment to indigenous propulsion technology development.   Electric Propulsion: A Leap Forward ISRO has been intensifying efforts to shift from conventional chemical propulsion to electric methods—such as Hall-effect and plasma thrusters—which offer vastly better efficiency and reduced satellite mass. The recently completed 1,000-hour life test of a 300 mN Xenon-based Stationary Plasma Thruster, powered at a full 5.4 kW, demonstrated a specific impulse at least six times higher than traditional chemical propulsion—affirming its readiness for future spacecraft missions. These electric thrusters are slated for initial validation aboard the upcoming Technology Demonstration Satellite (TDS-01), particularly for performing orbit-raising maneuvers to geostationary orbit. The success of this life test not only attests to the thruster's robustness but also signals a new era in ISRO’s satellite propulsion capabilities.   LPSC: The Propulsion Powerhouse LPSC, established in 1985, is the backbone of ISRO’s propulsion systems development. With its headquarters in Thiruvananthapuram and a significant satellite propulsion unit in Bengaluru, LPSC has long enabled innovation in both liquid and cryogenic propulsion stages, thrust control electronics, and satellite thrusters. Its facilities also include the ISRO Propulsion Complex (IPRC) at Mahendragiri, where critical engine and system-level tests are conducted. The centre has delivered numerous key technologies—ranging from monopropellant thrusters and pressure transducers to the cryogenic CE-20 engine, now serving as the upper-stage powerhouse for LVM3 launches, including those supporting ISRO’s ambitious Gaganyaan human spaceflight program.   Broader Propulsion Landscape The handover comes in the wake of broader advancements in ISRO’s propulsion portfolio. Recent developments include robust hot-testing of the Service Module Propulsion System for Gaganyaan, integration of reaction control thrusters into the crew module, and extensive tests validating human-rating standards for LVM3 components. Additionally, ISRO is laying the groundwork for future electric-only satellites, with GSAT-20 projected to deploy fully electric propulsion systems in orbit. With LPSC's electronics now in ISRO’s hands, the next phase will focus on integrating these control systems with electric thrusters, conducting rigorous testing, and ultimately validating them in space. Success would mean dramatically improved mass efficiency for satellites, enabling higher payload capacity and longer mission lifespans. As ISRO moves toward fully electric propulsion in space science and communication satellites, LPSC’s role remains pivotal—designing, validating, and delivering the advanced systems that empower India's space ambitions.   Why This Matters Technological Leap: Electric propulsion promises dramatically higher efficiency—boosting satellites’ payload and mission longevity. Indigenous Capability: LPSC’s development showcases India’s growing self-reliance in advanced spacecraft systems. Mission Futureproofing: From TDS-01 to Gaganyaan and beyond, these efforts dovetail with ISRO’s strategic vision for human spaceflight and electric satellite constellations

 Space & Technology 

Sriharikota, August 24, 2025 – The Indian Space Research Organisation (ISRO) has successfully completed the first Integrated Air Drop Test (IADT-01) for its ambitious Gaganyaan human spaceflight mission, marking a major milestone in India’s journey toward crewed space exploration. The test, conducted in close coordination with the Indian Air Force, Defence Research and Development Organisation (DRDO), Indian Navy, and Indian Coast Guard, demonstrated the end-to-end functioning of the parachute-based deceleration system that will ensure the safe return of astronauts from space. ISRO confirmed the achievement through its official communication, describing the test as a critical precursor to validating crew module safety and recovery operations.   A Multi-Agency Effort The trial underscored the synergy between multiple Indian agencies, as the test required precise execution involving aircraft deployment, parachute deployment sequences, tracking, and recovery. Naval and Coast Guard assets were deployed to simulate recovery operations, reflecting the operational model for the actual human spaceflight mission.   Progress on the Gaganyaan Mission The Gaganyaan program—India’s first attempt at sending humans into space—has seen consistent progress over the past year. Human Rated Launch Vehicle (HLVM3): India’s trusted LVM3 heavy-lift rocket has been modified with additional crew safety features and successfully completed development and ground testing. Orbital Module Development: Both the Crew Module and Service Module have had their propulsion systems validated. The crew module, designed to safely carry astronauts, has already passed structural and environmental tests. Crew Escape System (CES): Five different types of motors for the escape system have been developed and tested. This mechanism will rapidly pull astronauts to safety in the event of a launch emergency. Infrastructure: India has established the Gaganyaan Control Centre, Orbital Module Preparation Facility, astronaut training facilities, and launch pad modifications at Sriharikota. Earlier, ISRO successfully carried out the TV-D1 flight test, which validated the performance of the CES during an actual launch scenario. Preparations are ongoing for the TV-D2 test flight along with additional parachute validation tests under the IADT series.   Operational Preparedness To ensure mission safety and reliability, ISRO has: Finalized the Crew Recovery Operations Plan, in coordination with the Navy and Coast Guard. Set up the Indian Data Relay Satellite System (IDRSS) to provide continuous communication with the crew in orbit. Integrated terrestrial tracking and feeder stations to guarantee real-time monitoring during all mission phases.   Upcoming Test Flights The first uncrewed Gaganyaan mission (G1) is progressing steadily. The C32-G stage, HS200 boosters, and CES motors have already been realized, and structural checks of both the crew and service modules have been completed. The uncrewed flight will serve as a dress rehearsal for subsequent crewed missions.   Vision Beyond Gaganyaan India’s human spaceflight roadmap extends well beyond Gaganyaan: Bharatiya Antariksh Station (BAS): India’s first modular space station, targeted for completion by 2035 with five modules. The first module has already received government approval. Human Lunar Mission by 2040: India aims to send astronauts to the Moon, with preliminary mission designs, launch strategies, and astronaut training protocols under development. These plans reflect India’s long-term ambition of becoming a leading spacefaring nation, not only achieving independent human spaceflight but also enabling extended human presence in low Earth orbit and beyond.   National Significance The IADT-01 success represents more than just a technical milestone. It symbolizes India’s growing confidence and capability in executing complex, high-stakes missions that involve multiple agencies and cutting-edge engineering. Once realized, Gaganyaan will place India among the elite group of nations—including the United States, Russia, and China—that have independently developed the capability to launch humans into space. Union Minister of State for Science and Technology Dr. Jitendra Singh emphasized that Gaganyaan will serve as a catalyst for innovation across defense, manufacturing, and advanced research, boosting national pride while strengthening India’s position in the global space community.   With the successful Integrated Air Drop Test, ISRO has taken a decisive step closer to sending Indian astronauts into space. The test validates a crucial safety system and showcases the country’s ability to integrate the efforts of its space agency, armed forces, and industry partners for a common national goal. The road ahead will see more uncrewed trials, human-rating of systems, and final mission rehearsals, leading up to the first Indian crewed spaceflight. Together with its planned space station and lunar mission roadmap, India is steadily moving toward becoming a pioneer in human space exploration, aligned with its vision of a Viksit Bharat by 2047.
