ISRO on Thursday said it has accomplished de-docking of the SpaDeX satellites, clearing the way for future missions such as exploring the moon, human spaceflight, and building its own space station. Union Minister Jitendra Singh announced the successful de-docking of satellites in a post on X. "SpaDeX satellites accomplished the unbelievable de-docking. This paves the way for smooth conduct of ambitious future missions including the Bharatiya Antriksha Station, Chandrayaan 4 & Gaganyaan," Singh said. "Congrats team ISRO. And heartening for every Indian," he said. Singh said Prime Minster Narendra Modi's continuous patronage keeps the spirits soaring. The SpaDeX mission was launched on December 30 last year when the Indian Space Research Organisation (ISRO) placed in orbit two satellites -- SDX01 and SDX02 -- to demonstrate the docking experiment in space. After several attempts, the space agency successfully docked the two satellites on January 16.
Ice could be present at more locations right beneath the Moon's surface at the poles than previously thought, a study of data collected by the Chandrayaan-3 mission has suggested. Large, yet highly local, changes in surface temperatures can directly affect the forming of ice, and looking into these ice particles can reveal "different stories about their origin and history", lead author, Durga Prasad Karanam, Faculty, Physical Research Laboratory, Ahmedabad told PTI. This can also tell us about how ice accumulated and moved through the Moon's surface over time, which can provide insights into the natural satellite's early geologic processes, he said. The findings are published in the journal Communications Earth and Environment. The Chandrayaan-3 mission, launched by the Indian Space Research Organisation (ISRO) from Bengaluru, achieved a soft landing near the Moon's south pole on August 23, 2023. The landing site was named the 'Shiv Shakti Point' three days later on August 26. For
Former ISRO chairman S Somanath has highlighted the cost-effectiveness of India's space programmes and noted that for the same satellite and share of work, the country will incur five-time less expenditure compared to the US for an upcoming mission. He was referring to the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The joint National Aeronautics and Space Administration (NASA)-Indian Space Research Organisation (ISRO) project will map the entire globe and provide data for understanding changes in Earth's ecosystems, ice mass, vegetation biomass, sea level rise, ground water and natural hazards. Somanath on Wednesday stressed on greater private sector role to push India's contribution in the global space economy from current 2 per cent to 10 per cent. Taking about NISAR, a joint Earth-observing radar mission, he said one part of the payload is being developed by the US, and the other by India. The former ISRO chief was speaking at an interactive session on the topic, "Indi
ISRO on Friday said it has developed and realised the ten-tonne propellant mixer for solid motors. Solid propulsion plays a crucial role in Indian Space Transportation Systems and vertical mixer is one of the critical equipment in solid motor production, ISRO said in a statement. "Solid propellants are the backbone of rocket motors, and their production requires precise mixing of highly sensitive and hazardous ingredients," the statement read. The space agency said that towards increasing the production scale of solid motor segments, Satish Dhawan Space Centre in Sriharikota in collaboration with Central Manufacturing Technology Institute (CMTI), Bengaluru has successfully designed and developed 10-tonne Vertical Planetary Mixers for processing the solid propellants. ISRO has termed it a significant technological marvel. It added that the 10-tonne vertical mixer is the world's largest solid propellant mixing equipment. The development involves collaboration with academia and ...
A day after ISRO successfully carried out the ignition trial of the indigenous CE20 cryogenic engine, its Chairman and Secretary of Department of Space V Narayanan on Saturday said that the test would be advantageous to missions. The Chairman also said there were no glitches as reported in the media in ISRO's first Space Docking Experiment (SpaDeX) mission. "We want to restart the cryogenic stage in the flight for mission advantages. So, we recently carried out a test towards that," Narayanan told PTI on the sidelines of the 15th Biennial Edition of Aero India International Seminar 2025, held in Bengaluru. On February 7, ISRO successfully carried out the ignition trial of the indigenous CE20 cryogenic engine powering the upper stage of LVM3, with a multi-element igniter under vacuum conditions, which simulates the engine ignition in the vacuum condition of space. This test was carried out in the High-Altitude Test Facility at ISRO Propulsion Complex in Mahendragiri, Tamil ...
ISRO on Saturday said that it has successfully carried out the ignition trial of the indigenous CE20 cryogenic engine powering the upper stage of LVM3, with a Multi-element igniter under vacuum conditions, which simulates the engine ignition in the vacuum condition of space. This test was carried out on Friday in the High Altitude Test Facility at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu, ISRO said in a statement. This engine is crucial for the Gaganyaan mission, India's ambitious crewed space mission. During this test, the ignition of the engine Thrust Chamber was carried out with a multi-element igniter in a vacuum, under the tank pressure conditions that are expected to prevail at the time of restarting the cryogenic engine in flight. The performance of the engine and the facility during the test was normal and as expected. Restarting a cryogenic engine is inherently complex and as part of the studies related to the restart operation, ISRO is exploring the initiation of
ISRO's attempts to place the NVS-02 satellite in the desired orbit suffered a setback after the thrusters on board the spacecraft failed to fire, the space agency said on Sunday. The NVS-02 satellite, which was crucial for India's own space-based navigation system, was launched on January 29 on board the GSLV-Mk 2 rocket which was ISRO's 100th launch from the spaceport at Shriharikota. "But the orbit raising operations towards positioning the satellite to the designated orbital slot could not be carried out as the valves for admitting the oxidizer to fire the thrusters for orbit raising did not open," the space agency said in an update to the GSLV-F15 mission on its website. The satellite is orbiting the Earth in an elliptical Geosynchronous Transfer Orbit (GTO) which is not suitable for the navigation system. "The satellite systems are healthy and the satellite is currently in elliptical orbit. Alternate mission strategies for utilising the satellite for navigation in an elliptica
Liquid Propulsion Systems Centre of ISRO has dispatched the Crew Module for the first uncrewed mission of Gaganyaan (G1) after successfully completing the integration of the liquid propulsion system, the space agency said on Wednesday. Gaganyaan will be ISRO's first attempt towards acquiring human spaceflight capabilities. Before sending the crew, the ISRO is planning to send uncrewed mission to the space under its Gaganyaan project. On 21 January 2025, the Liquid Propulsion Systems Centre (LPSC) of ISRO dispatched the Crew Module for the first uncrewed mission of Gaganyaan (G1), after successfully completing the integration of the liquid propulsion system, ISRO said in a statement. LPSC, Bengaluru has dispatched the module to Satish Dhawan Space Centre, Sriharikota, officials said. According to the space agency, the Crew Module Propulsion System (CMPS) is a bi-propellant based Reaction Control System (RCS) and is meant for precise three axis control namely Pitch, Yaw and Roll, of
ISRO chairman V Narayanan on Saturday said the space-docking experiment (SpaDeX) of satellites was successful and the results will be useful for multiple purposes, including future missions like Chandrayaan 4, Gaganyaan and India's space station. Narayanan, who arrived in Kerala after the successful space-docking test, told reporters at the airport here that it was a team effort by the ISRO and the results of the test were being reviewed. "Right now the situation is that all the things are successfully docked and it is in space safely. Now we are studying all the results. My team is reviewing the results and we will take the proper decision at the proper time," he said. The scientist further said that the docking experiment would be useful for multiple purposes. Giving details, he said that it will be useful for the Chandrayaan 4 mission as two rockets will be used to carry to space the over 9,000 kg module that will subsequently land on the moon for sample collection. He said tha
The two Space Docking Experiment (SpaDeX) satellites that the ISRO aims to unite in orbit are currently separated by a distance of 230 m, with their health status deemed 'normal', the space agency said on Saturday. On Friday evening, the satellites were separated by 1.5 kms. ISRO has said that the distance would be reduced to 500 m by Saturday morning. In a post on 'X', ISRO said, "Arrested at Inter Satellite Distance (ISD) of 230 m, all sensors are being evaluated. Spacecraft's health is normal." The space agency, however, has not committed to a date for conducting the docking experiments, which will bring the satellites together in space. The SpaDeX project has already missed two announced schedules for docking experiments on January 7 and 9. ISRO successfully launched the Space Docking Experiment (SpaDeX) mission on December 30. The PSLV C60 rocket carrying two small satellites, SDX01 (Chaser) and SDX02 (Target), along with 24 payloads, had lifted off from the first launchpad
ISRO Chairman S Somanath said on Friday that industries have a phenomenal role to play in achieving India's Space Vision 2047, rolled out by Prime Minister Narendra Modi. ISRO chairman-designate V Narayanan also echoed the same view. In his pre-recorded inaugural speech, at the biennial National Aerospace Manufacturing Seminar (NAMS) 2025, Somanath said that the industries will face significant challenges as their collaboration with the space programme is going to increase substantially. One of the challenges would be the regular production of rockets, satellites and other systems required for the space programme and the other would be engineering, manufacturing and supplying items like new space crafts and systems, miniature electronics, large propulsion tanks and engines, he said. "They have to be produced in numbers to meet the tight schedules," he added. He said the task was a huge one as the strength of the space community in the public sector was not increasing ...
The Indian Space Research Organisation's (ISRO) LVM3 rocket will launch in March a communication satellite of a US-based firmT SpaceMobile that plans to provide space-based cellular broadband network services on smartphones. "The commercial LVM3-M5 mission, set for March, will deploy BlueBird Block-2 satellites under a contract with the US-basedT SpaceMobile," an official statement said. The statement came after Science and Technology Minister Jitendra Singh reviewed the functioning of the Department of Space with senior officials, including the outgoing ISRO chairman S Somanath, his successor V Narayanan and Pawan Kumar Goenka, Chairman of Indian National Space Promotion and Authorisation Centre (IN-SPACe). Narayanan, who will succeed Somanath on January 14, during the meeting outlined a strategic roadmap for expanding the ISRO's global footprint. The joint NASA-ISRO satellite NISAR and a navigation satellite NVS-02 are set for launch in February on board two separate missions o
ISRO on Monday said the docking experiment of SpaDeX satellites scheduled for January 7 is now postponed to January 9. The Bengaluru-based space agency said the docking process requires further validation through ground simulations based on an abort scenario identified on Monday. "The SpaDeX Docking scheduled on (January) 7th is now postponed to 9th. The docking process requires further validation through ground simulations based on an abort scenario identified today," ISRO said in a post on 'X'. ISRO had successfully launched the ambitious Space Docking Experiment (SpaDeX) mission on December 30. The PSLV C60 rocket carrying two small satellites, SDX01 (Chaser) and SDX02 (Target), along with 24 payloads, had lifted off from the first launchpad of the Satish Dhawan Space Centre in Sriharikota, and about 15 minutes after liftoff, the two small spacecraft weighing about 220 kg each were launched into a 475-km circular orbit as intended.
