In a precautionary but necessary move, the highly anticipated Ax-4 crewed mission to the International Space Station (ISS) has been deferred by SpaceX following the detection of a liquid oxygen (LOX) leak during a static fire test of the Falcon 9 launch vehicle. The mission, which was originally scheduled to lift off on June 11, 2025, has now entered a holding pattern while engineers resolve the technical anomaly. Static Fire Test Uncovers Propulsion Bay Issue The issue emerged during a routine static fire test, a standard pre-launch procedure designed to assess the readiness and performance of Falcon 9’s first stage engines. The hot fire lasted approximately seven seconds, and while it initially appeared nominal, post-test inspections by SpaceX engineers identified an unexpected LOX leak in the propulsion bay of the booster. Given the cryogenic and highly volatile nature of liquid oxygen, any leak—even a minor one—poses significant risks to mission integrity. Technical teams from SpaceX, Axiom Space, and ISRO immediately convened to assess the issue and agreed unanimously to postpone the launch pending corrective measures. Safety First: Rectification Underway The leak, while not deemed catastrophic, necessitates hardware-level intervention. SpaceX has initiated rectification protocols, including booster disassembly for close-up inspection, potential component replacement, and system revalidation through a second static fire test. These steps are crucial for restoring full confidence in the launch system before a new countdown can begin. Revised Launch Date Awaited A new launch date for the Ax-4 mission will be determined once the issue is fully resolved and pending range availability from NASA’s Kennedy Space Center. The teams are committed to ensuring that all safety, performance, and human-rating standards are exceeded, not merely met. As part of this diligence, the mission readiness review (MRR) will be re-conducted once repairs are complete, and the final green light will depend on successful completion of all validation protocols. Astronaut Crew in Good Spirits Among the Ax-4 mission crew is Group Captain Shubhanshu Shukla, a decorated Indian Air Force officer who is poised to become one of the few Indians to travel into space. While the delay may be disappointing, it underscores the stringent safety culture that governs all human spaceflight missions. Gp Capt Shukla, along with the international crew from Axiom Space, remains in quarantine and readiness, undergoing routine simulations and health checks as they await their moment in history. Mission Significance The Ax-4 mission is a pivotal private spaceflight venture led by Axiom Space in partnership with SpaceX and global space agencies. Once launched, it will transport the crew to the ISS for a series of scientific, medical, and technological experiments, many of which are being conducted in partnership with institutions from India, the UAE, and Europe.

In a bold step toward reshaping the future of satellite technology, two former ISRO scientists, Christopher Parmar and Anupam Kumar, have launched a space-tech startup named Orbitt Space, based in Ahmedabad. Founded in February 2025, the company has already made headlines by securing $1 million in pre-seed funding to develop an innovative propulsion system designed for Ultra Low Earth Orbit (ULEO) — a region of space that lies below 250 kilometers in altitude. Unlike conventional satellite zones, ULEO remains largely unexplored due to intense atmospheric drag and fuel limitations, making sustained operations nearly impossible with traditional propulsion methods. Satellites in this region typically exhaust their fuel quickly, limiting mission life to just a few days or weeks. But Orbitt Space has a game-changing solution. The startup is building a next-generation air-breathing electric propulsion system, a technology that draws in the residual gases present in the atmosphere at ULEO levels and uses them as a propellant. This system eliminates the need to carry bulky fuel tanks, enabling satellites to operate continuously for 5 to 7 years in this challenging environment — a feat that was once thought unattainable. By using the orbit’s own resources to generate thrust, Orbitt’s approach not only extends mission duration but also addresses the growing problem of space debris. Unlike satellites in higher orbits that can remain floating as junk for decades, satellites in ULEO naturally deorbit due to atmospheric drag, ensuring they don’t become long-term clutter in space. The benefits of operating in ULEO extend far beyond sustainability. Because of the lower altitude, satellites can capture sharper images and deliver data with faster response times, making them ideal for applications like real-time Earth observation, low-latency communication, climate monitoring, and national security surveillance. Moreover, since ULEO has much lower radiation levels compared to higher orbits, Orbitt's satellites can use commercial-grade electronics instead of expensive, radiation-hardened components — slashing costs and simplifying design. While Low Earth Orbit (LEO), especially the 500–700 km range, has become increasingly congested with more than 40,000 tracked objects and millions of smaller debris fragments, ULEO remains a clean and open zone. Orbitt sees this as a “blue ocean” opportunity, offering safer, cheaper, and more efficient satellite operations in an underutilized part of space. The $1 million raised — led by pi Ventures with support from IIMA Ventures — will be used to build a highly skilled team of 8 to 10 scientists and engineers, many of them expected to come from ISRO. The immediate focus is on developing a working prototype of the propulsion system and conducting environmental tests. The company has laid out a clear three-phase roadmap: first, building and validating the prototype on the ground; second, performing rigorous testing for space qualification; and third, launching their first operational satellite into ULEO by 2027 or 2028. Orbitt’s proximity to IIM Ahmedabad gives it access to ISRO testing infrastructure, while discussions are already underway with major potential clients, including TATA Advanced Systems. The startup is also exploring partnerships through IN-SPACe, the Indian government’s initiative to foster private sector collaboration in the space domain. Looking ahead, Orbitt Space envisions a major shift in the $13 billion satellite market, with many operations moving from LEO to ULEO due to the clear advantages in performance, cost, and sustainability. Their air-breathing propulsion technology could play a central role in this transition, offering a pathway to cleaner, more durable, and responsive satellites. By harnessing their ISRO expertise and pushing the boundaries of what’s possible in orbital mechanics, Orbitt Space is not just launching a new product — they are opening up an entirely new frontier in space exploration. Their innovation could place India at the forefront of next-generation satellite technology and set new standards for how we think about access to and sustainability in outer space.

In a monumental leap for atmospheric sciences and Earth observation capabilities, India is poised to become the first country in the world to operate a high-resolution global weather forecasting system, aptly named the Bharat Forecast System (BFS). This groundbreaking initiative, led by the Ministry of Earth Sciences (MoES), marks a transformative step in the country’s ambition to emerge as a leader in climate modeling and disaster preparedness. With this system, India will not only serve its own billion-plus population with unparalleled accuracy but also provide meteorological services on a truly global scale — a feat previously unachieved at this resolution by any nation. The Technology Behind Bharat Forecast System At the heart of the Bharat Forecast System lies a Numerical Weather Prediction (NWP) model with a resolution of 5 km x 5 km globally, compared to the 12 km x 12 km or coarser grids used in most leading weather models today. This allows the model to capture smaller-scale weather phenomena, such as thunderstorms, cyclonic circulations, and heavy rainfall events, with much greater fidelity. The system is powered by advanced data assimilation algorithms, integrating real-time information from satellites, Doppler weather radars, buoys, aircraft, weather balloons, and land-based observational stations. Crucially, the BFS leverages India's growing network of satellites, including INSAT-3D/3DR and SCATSAT-1, alongside future missions like Oceansat-3 and the upcoming Mausam satellite. To manage the sheer computational demands of such high-resolution modeling, India will deploy one of the world’s fastest weather-dedicated supercomputers, expected to have a processing capacity exceeding 30 petaflops, potentially surpassing even those used by NOAA (USA) and ECMWF (Europe). A Global Benchmark: How BFS Compares to Other Leading Systems Globally, countries and organizations maintain sophisticated weather forecasting systems: ECMWF (European Centre for Medium-Range Weather Forecasts): Regarded as the gold standard for medium-range forecasting, the ECMWF model operates at approximately 9 km resolution, offering 15-day global forecasts with high accuracy. However, BFS's 5 km resolution will provide better spatial granularity. NOAA (USA): The Global Forecast System (GFS) has been recently upgraded to the FV3 dynamical core, operating at a 13 km resolution globally. NOAA also maintains the High-Resolution Rapid Refresh (HRRR) system, but it's limited to the continental US. UK Met Office: Uses the Unified Model, with global forecasts at 10 km resolution, and finer resolution models only for UK and surrounding areas. Japan Meteorological Agency (JMA): Operates its GSM (Global Spectral Model) at about 20 km resolution, though Japan excels in typhoon forecasting with regional models. While these systems are highly advanced, they either operate at coarser resolution globally or reserve their high-resolution models for national or regional scales. India’s BFS stands out by offering uniform 5 km resolution coverage across the entire globe, a technical and computational marvel. Strategic Significance of Bharat Forecast System Global Climate Stewardship: BFS underscores India’s shift from being a data consumer to a data provider in the realm of meteorological and climate services. It will empower developing nations, especially in Africa and South Asia, with free access to precise forecasts — a role similar to what the ECMWF plays for Europe. Disaster Resilience: India is prone to extreme weather events like cyclones, floods, and droughts. With a high-resolution model, local authorities can issue more accurate and timely warnings, potentially saving thousands of lives annually. Agricultural Productivity: Given India’s large agri-dependent population, BFS can support precision agriculture, helping farmers decide optimal sowing times, irrigation schedules, and harvest periods with better weather predictability. Aviation, Maritime, and Energy Sectors: High-resolution forecasts will benefit air traffic management, shipping routes, renewable energy forecasting (solar and wind), and urban infrastructure planning. What Comes Next The Bharat Forecast System is expected to be operational by mid-to-late 2025, with a phased rollout starting in the Indian subcontinent. The system will incorporate machine learning modules to refine predictive accuracy over time, especially in complex terrains like the Himalayas and coastal regions. The BFS is part of India’s broader vision under the National Mission on Weather and Climate Services (NMWCS), which also includes enhanced ocean modeling, monsoon forecasting, and urban microclimate monitoring. Final Thoughts With the launch of the Bharat Forecast System, India is not just catching up with the global elite in weather science — it is setting the new benchmark. In a world grappling with climate volatility and an increasing frequency of extreme weather events, BFS represents Bharat’s scientific resilience, ambition, and leadership. This is more than a technological achievement — it is a powerful expression of India’s commitment to "Vasudhaiva Kutumbakam" — the world is one family — by offering its most advanced weather intelligence to humanity at large.

SpaceX’s ambitious Starship program faced another major setback when its ninth test flight ended in failure on May 27, 2025. Despite a promising launch and new milestones, the spacecraft ultimately lost control in space and broke apart during re-entry, crashing into the Indian Ocean. The mission lifted off from SpaceX’s Starbase launch site in Texas, powered by the massive Super Heavy booster carrying the Starship upper-stage. This flight was particularly important as it marked the first time SpaceX reused a Super Heavy booster—an important step toward the company's goal of creating a fully reusable rocket system. The launch initially went according to plan. The Super Heavy booster separated cleanly and began its return to Earth. However, SpaceX lost communication with the booster before it could attempt a safe splashdown in the ocean. It is now believed the booster crashed into the sea, ending its journey abruptly. Meanwhile, the Starship upper-stage continued its flight and successfully reached suborbital space. But problems began to surface when the payload doors refused to open, preventing the release of mock satellites that were part of the test. Things took a critical turn around 30 minutes into the mission when a fuel leak led to a loss of attitude control. The spacecraft began spinning uncontrollably, making it impossible to align properly for re-entry into Earth’s atmosphere. Without proper orientation, Starship re-entered too early and at the wrong angle. The intense heat and forces of re-entry caused it to break apart in what SpaceX calls a “rapid unscheduled disassembly”—a technical term for an unplanned and catastrophic failure. Despite the loss, this flight went farther than any previous Starship test. Earlier attempts had ended in explosions shortly after takeoff, while this mission managed to reach space and provided valuable data that engineers can use to improve the design. The failed mission also had consequences on the ground. As a safety precaution, the US Federal Aviation Administration briefly halted departures from several Florida airports to avoid any danger from potential debris. SpaceX remains undeterred. Elon Musk and his team are determined to continue testing and developing Starship, which plays a key role in NASA’s Artemis mission to return humans to the Moon and in Musk’s larger dream of sending humans to Mars. Each test flight, success or failure, brings them one step closer to that goal.

On May 18, 2025, the Indian Space Research Organisation (ISRO) faced a rare setback when its trusted Polar Satellite Launch Vehicle (PSLV) failed to deliver the EOS-09 satellite into orbit. This mission marked the 101st launch for ISRO and the 63rd for the PSLV series. Launch Overview The PSLV-C61 lifted off at 5:59 AM IST from the Satish Dhawan Space Centre in Sriharikota. The rocket's first two stages performed as expected, propelling the vehicle along its planned trajectory. However, approximately 203 seconds into the flight, during the third stage, telemetry data indicated a sudden drop in chamber pressure. This anomaly led to the rocket deviating from its intended path, resulting in the mission's failure. Suspected Cause: Flex Nozzle Malfunction Initial analyses suggest that the failure may have been due to a malfunction in the third stage's flex nozzle system. The flex nozzle is a critical component that allows for precise steering of the rocket by adjusting the direction of thrust. A malfunction in this system can lead to misalignment of thrust, causing the rocket to veer off course. Impact on EOS-09 Satellite The EOS-09 satellite, also known as RISAT-1B, was designed to enhance India's Earth observation capabilities. Equipped with a C-band Synthetic Aperture Radar (SAR), it was intended to provide high-resolution images of Earth's surface, regardless of weather conditions, day or night. The loss of this satellite is a significant setback for applications such as border surveillance, disaster management, and agricultural monitoring. ISRO's Response ISRO has established a Failure Analysis Committee to investigate the root cause of the anomaly. The committee will examine manufacturing records, test protocols, and telemetry data to identify the precise reason for the failure. ISRO Chairman V. Narayanan stated, "First two stages performed as expected. In the third stage, we observed less chamber pressure. The mission could not be accomplished." PSLV's Track Record Despite this incident, the PSLV remains one of the world's most reliable launch vehicles, with only three failures in 63 launches since its inception. The last failure occurred in 2017 during the PSLV-C39 mission. The PSLV has been instrumental in deploying satellites for various applications, both domestically and internationally. The PSLV-C61 mission's failure underscores the complexities involved in space missions and the importance of rigorous testing and quality assurance. The findings from the Failure Analysis Committee will be crucial in implementing corrective measures to prevent similar issues in future launches. ISRO's commitment to learning from setbacks and enhancing its systems will be vital in maintaining its position as a leading space agency.

India’s space programme has taken another significant step forward as the Second Stage (GS2) of the GSLV launch vehicle was officially flagged off on March 24, 2025. The ceremony took place at the ISRO Propulsion Complex (IPRC) in Mahendragiri, with Dr. V. Narayanan, Secretary of the Department of Space (DOS) and Chairman of ISRO, leading the event. Senior officials from the ISRO Propulsion Complex (IPRC) and Vikram Sarabhai Space Centre (VSSC) were also present during this important milestone. This GS2 stage is crucial for the upcoming GSLV-F16 mission, which is set to launch the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite into space. The NISAR mission is a prestigious joint project between NASA and ISRO, aimed at providing detailed Earth observation data to monitor changes in ecosystems, ice mass, sea levels, and natural disasters. The Second Stage (GS2) is a liquid-fuel stage of the GSLV (Geosynchronous Satellite Launch Vehicle). It uses a powerful Vikas engine that runs on a combination of UH25 (a mix of unsymmetrical dimethylhydrazine and hydrazine hydrate) and nitrogen tetroxide as propellants. The GS2 stage is designed to ignite after the solid-fueled first stage (S139) burns out, providing the required thrust to carry the satellite further into its orbit. Specifications of GSLV Second Stage (GS2) Engine: Vikas engine Propellant Type: Liquid (UH25 and N2O4) Propellant Mass: Around 40 tonnes Thrust: Approximately 725 kN Burn Time: Around 150 seconds The GS2 stage was transported from Mahendragiri to the launch complex at Sriharikota, where preparations for the GSLV-F16/NISAR mission have already begun in the first week of April 2025. This marks the beginning of a crucial phase in the mission's launch campaign activities. The NISAR satellite is expected to be one of the most advanced Earth observation satellites ever built, capable of monitoring environmental changes with unmatched accuracy. It carries a dual-frequency radar system, operating in both L-band and S-band, to provide high-resolution data under all weather conditions, day and night. The successful flagging off and transportation of the GS2 stage underline ISRO’s steady progress toward another landmark launch. The GSLV-F16 mission will not only enhance India’s space capabilities but also strengthen international collaborations in the field of Earth observation and climate monitoring.

China is taking bold steps toward establishing a long-term human presence on the Moon. The country is now considering building a nuclear reactor to supply continuous power for a future lunar base, as part of its International Lunar Research Station (ILRS) project, which it is developing jointly with Russia. Beijing’s ambitions in space have been growing steadily. China plans to land its astronauts on the Moon by 2030 and aims to build a permanent, crewed base on the lunar surface by 2035. To support this long-term goal, the country is focusing not only on space exploration missions but also on how to generate reliable power on the Moon’s surface — where sunlight is limited during long lunar nights that last around 14 Earth days. Why Nuclear Power on the Moon? During a presentation at a space industry event in Shanghai, Pei Zhaoyu, chief engineer for China’s Chang’e-8 mission scheduled for 2028, explained that the ILRS will need a dependable source of energy to sustain operations. While solar panels will play a role, their efficiency drops drastically during the long lunar nights. This is where nuclear energy comes in. A nuclear reactor on the Moon would act as the primary power source for the ILRS, ensuring a steady supply of electricity and heat, even when sunlight isn’t available. The concept is considered crucial for running life support systems, research labs, mining operations, and communication equipment at the lunar base. What Will the Lunar Reactor Look Like? Though official specifications have not been fully released, Pei’s presentation suggested that the ILRS energy system will include: Small modular nuclear reactors (SMRs) capable of operating in extreme lunar environments. Pipelines and buried cables to transfer heat and electricity between different parts of the base. Large solar power arrays for use during lunar days. The reactor is expected to generate at least 1 megawatt (MW) of electrical power, which is enough to support basic infrastructure and scientific operations for a small crew. By comparison, NASA has also been exploring similar technologies under its Fission Surface Power project, aiming to deploy a 40-kilowatt reactor on the Moon by the end of the decade. China’s proposal reportedly focuses on using compact, portable reactors that can be safely transported to the Moon aboard a robotic lander. Once there, the reactor would be deployed in a shielded area to reduce radiation risks to astronauts and equipment. Russia’s Role in the Project Russia, a co-partner in the ILRS, has a long history of developing space-based nuclear power systems. According to Wu Weiren, chief designer of China’s lunar exploration program, Russia holds an advantage in this area and will likely contribute valuable expertise in nuclear technology and reactor designs suitable for lunar conditions. What’s Next? The Chang’e-8 mission in 2028 will test several key technologies needed for the ILRS, including resource extraction from lunar soil, 3D printing structures using lunar materials, and initial power generation systems. The experience gained from this mission will help refine the nuclear reactor concept and other infrastructure plans ahead of the crewed base’s construction, targeted for 2035. If successful, China’s lunar nuclear reactor would mark a major leap in space power systems and could eventually support longer-term human settlements on the Moon and even Mars. China’s plan to build a nuclear reactor on the Moon is a sign of its growing confidence and ambition in space exploration. By addressing the challenges of lunar night and ensuring a continuous power supply, China aims to lay the groundwork for a permanent human base on the Moon within the next decade — a step that would reshape the future of space exploration.
