A Chinese reusable spacecraft linked to the Shenlong program has triggered fresh global scrutiny after tracking data showed a separate object appearing in close proximity during its latest orbital phase. The event, observed in June 2026, has added new uncertainty around the nature of China’s secretive spaceplane operations. Tracking data reveals unexpected separation in orbit Independent space surveillance firm LeoLabs reported detection of a new object near the Shenlong spacecraft during routine orbital monitoring. The timing and proximity suggested a possible release or separation event from the main vehicle. The object was later incorporated into the US Space Force satellite catalog, allowing continued tracking through global space surveillance networks. What the Shenlong spaceplane is designed for Shenlong spaceplane is China’s experimental reusable orbital vehicle designed to launch via rocket and return to Earth like a conventional aircraft. The system is believed to support long-duration missions involving orbital testing, reconnaissance experiments, and reusable spacecraft technologies. It is often compared to the US X-37B program due to its similar operational profile and secrecy surrounding mission objectives. Launch background and mission profile The spacecraft associated with this mission was launched from the Jiuquan Satellite Launch Center aboard a Long March 2F rocket. Since launch, Chinese authorities have released minimal operational details, leaving external analysts to rely heavily on radar tracking, orbital behavior, and third-party observations to interpret mission activity. Why the object detection raised questions The appearance of a separate object in close orbital proximity has led analysts to consider several possibilities, including experimental deployment, satellite servicing tests, or controlled separation of hardware. While none of these scenarios have been confirmed, the pattern aligns with rendezvous and proximity operations (RPO), a capability used for inspecting or interacting with objects in space. Strategic implications and global monitoring The development is being closely monitored because RPO technology has dual-use applications. It can support peaceful maintenance missions but also enable advanced surveillance or counter-space capabilities. As a result, both US and international tracking systems continue to observe Shenlong missions for behavioral patterns that may indicate evolving strategic capabilities. Ongoing uncertainty around mission details Despite growing external analysis, no official clarification has been issued regarding the nature of the detected object. This lack of transparency keeps the mission under active observation, with each new orbital event contributing to broader assessments of China’s reusable spacecraft program and its long-term strategic direction.

Interstellar comet 3I/ATLAS reveals origins in an alien solar system as astronomers analyzing the rare celestial object have uncovered evidence suggesting it formed in conditions vastly different from those that shaped our own planetary system. The comet, known as 3I/ATLAS, was first detected passing through our solar system in July and is only the third known interstellar object ever observed in such a trajectory. New findings, published on Wednesday, April 23, 2026, in the journal Nature Astronomy, indicate that the comet likely originated in an extremely cold and distant region of another planetary system. Researchers used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to observe the comet in early November, shortly after it made its closest approach to the sun. The study marks the first time scientists have detected deuterium, a heavier isotope of hydrogen, in an interstellar object. This form of hydrogen is typically found in deuterated water, also known as semi-heavy water. According to lead researcher Luis Eduardo Salazar Manzano of the University of Michigan, the concentration of deuterium in 3I/ATLAS is more than 40 times higher than levels found in Earth’s oceans and over 30 times higher than in comets within our solar system. Such unusually high levels suggest that the comet formed in an environment with extremely low temperatures—below 30 Kelvin, or approximately minus 405 degrees Fahrenheit. Scientists believe this indicates formation in the outer regions of a protoplanetary disk, far from its host star, where icy materials can preserve their original chemical signatures for billions of years. Further analysis suggests that 3I/ATLAS may be up to 11 billion years old, making it significantly older than our solar system, which formed about 4.5 billion years ago. The preserved water within the comet likely dates back to the early stages of the Milky Way, offering a rare glimpse into the galaxy’s ancient conditions. Researchers also noted that standard water (H₂O) was not directly detected during observations, likely due to instrument sensitivity limits. However, the clear detection of deuterated water underscores the comet’s unusual composition and reinforces its value as a scientific “time capsule.” Experts say interstellar objects like 3I/ATLAS provide unique insights into how planetary systems form and evolve across the universe. Future observations from facilities such as the Vera C. Rubin Observatory are expected to identify more such objects, potentially helping scientists determine whether 3I/ATLAS is an anomaly or part of a broader population of chemically distinct comets. By studying these rare visitors, astronomers hope to better understand how the composition of planets—and even the building blocks of life—may differ across the galaxy, offering new perspectives on the origins of planetary systems beyond our own.

India’s Space Minister Dr. Jitendra Singh has said that there is no indication of sabotage behind a series of recent failures involving the Indian Space Research Organisation, even as repeated setbacks to strategic missions have triggered concern within policy and defence circles. The remarks come after three out of six ISRO missions launched from Indian soil over the past year failed, all of them linked to national security and strategic objectives. Speaking at a press briefing in New Delhi, Dr. Singh said that no report pointing to sabotage has been received so far. He clarified that while he is responsible for overseeing space launches, investigations related to sabotage or hostile interference fall under the purview of other ministries such as defence, home affairs, or external affairs. The minister added that, as of now, there is no information to suggest external interference in the recent launch failures. The comments follow two rare back-to-back mid-flight failures of ISRO’s Polar Satellite Launch Vehicle, a rocket that has long been considered the agency’s most dependable platform. Over a 33-year operational history, the PSLV had suffered only four major failures prior to 2025. The failures in May 2025 and January 2026, both occurring during the third stage of flight, have therefore raised serious questions about reliability and corrective action. Dr. Singh addressed public speculation that ISRO may have failed to rectify earlier faults, stating that the two PSLV failures had different technical causes despite occurring at the same stage. He expressed confidence in ISRO’s internal failure appraisal process, describing it as thorough and analytical. Traditionally, ISRO has publicly released summaries of mission failure analyses, contributing to its image as a transparent space agency. However, in recent cases, that practice has not been consistently followed. The failure analysis report of the PSLV-C61 mission in May 2025 was submitted to the Prime Minister’s Office but not released publicly. Similarly, no detailed technical update has been shared regarding the PSLV-C62 failure in January 2026 beyond ministerial statements. January 2026 – PSLV-C62 / EOS-N1 The PSLV-C62 mission on January 12, 2026, was ISRO’s first launch of the year and marked the PSLV’s return to flight after a setback in May 2025. The primary payload was EOS-N1, also known as Anvesha, a hyperspectral Earth observation satellite developed by the Defence Research and Development Organisation. The satellite was designed to operate at an altitude of 511 kilometres and provide advanced material identification capabilities by analysing reflected light across multiple wavelengths. The mission also carried 15 co-passenger satellites. A mid-flight failure during the third stage of the PSLV resulted in the loss of the rocket and all onboard satellites, ending the mission prematurely. May 2025 – PSLV-C61 / EOS-09 On May 18, 2025, ISRO’s PSLV-C61 mission failed approximately six minutes after liftoff. According to ISRO officials, performance was normal up to the second stage before an anomaly was observed during third-stage operation. The EOS-09 satellite, a radar imaging platform capable of all-weather, day-and-night surveillance, was lost along with the launch vehicle. Despite the strategic importance of the mission, ISRO did not release a public failure analysis, a departure from past practice. January 2025 – GSLV-F15 / NVS-02 On January 29, 2025, ISRO launched the NVS-02 navigation satellite aboard the GSLV-F15 rocket during the 100th launch from the Sriharikota spaceport. While the rocket successfully placed the satellite into its initial orbit, the satellite failed to fire its onboard engines, preventing it from reaching its designated operational orbit. The failure rendered NVS-02 unusable for its intended role within India’s NAVIC regional navigation system, which serves both civilian agencies and the armed forces. August 2021 – GSLV-F10 / EOS-03 In August 2021, ISRO launched the EOS-03 satellite, previously known as GISAT-1, aboard the GSLV-F10 rocket. Designed for near real-time Earth observation and disaster monitoring, the mission failed due to a malfunction in the cryogenic upper stage. ISRO later identified a valve leak in the liquid hydrogen tank as the cause of the failure. August 2017 – PSLV-C39 / IRNSS-1H The PSLV-C39 mission in August 2017 failed after the satellite remained trapped inside the rocket’s heat shield due to a separation failure. Although all other flight events proceeded as planned, the navigation satellite could not be deployed, resulting in the loss of a critical component of the Indian Regional Navigation Satellite System. The cumulative impact of these strategic mission failures over the past nine years is significant. Financial estimates suggest losses amounting to several hundred million dollars, excluding the cost of rebuilding and relaunching replacement missions. Beyond monetary loss, delays in deploying indigenous navigation and surveillance satellites force greater reliance on foreign systems, affecting strategic autonomy. ISRO has indicated that each failure was caused by a different subsystem or component, reinforcing the reality that spaceflight is a zero-error domain where even minor defects can have catastrophic consequences. While each failure contributes valuable lessons, the repeated setbacks have slowed the deployment of key space-based capabilities developed by Indian scientists, placing renewed focus on reliability, transparency, and long-term mission planning.

The Indian Space Research Organisation experienced a tense morning on Tuesday after the Polar Satellite Launch Vehicle C62 lifted off from the Satish Dhawan Space Centre in Sriharikota at 10.18 am carrying a total of 16 satellites. The mission initially appeared to progress as planned, with scientists closely monitoring each phase of the flight. However, around 30 minutes after liftoff, ISRO confirmed that the mission had encountered an anomaly during the third stage of the launch sequence, r
