Isro launches EOS-05, India's 1st imaging satellite in geosynchronous orbit

The 2,367-kg EOS-05, India's heaviest Earth observation satellite so far, was placed in its intended sub-geosynchronous transfer orbit about 18 minutes after lift-off

Gaganyaan's first uncrewed mission likely to launch this year: Isro chief

ISRO chief V Narayanan on Friday said that "vigorous, systematic work," is on for the launch of the first uncrewed Gaganyaan mission during this calendar year. The launch of the earth observation satellite (GSLV-F17/EOS-05) is the first success for ISRO during this financial year, Narayanan said adding, "reward for hard work is more work." Accordingly, the ISRO team, along with industries and other organisations, is working on the first uncrewed Gaganyaan mission. In his address following the successful launch of EOS-05, he said that activities were underway very "vigorously and systematically," for the uncrewed mission launch during this calendar year. Praising Prime Minister Narendra Modi for his leadership, Narayanan said that six more launches, including the navigation satellite NVS-03, are targeted for this financial year. Later, addressing a press conference, the ISRO chief said the earth observation satellite's operational lifetime is nine years and dismissed speculations t

Isro launches India's first imaging satellite in geostationary orbit

ISRO on Friday made its way into history books yet again with the successful launch of the country's first ever imaging satellite in geo-orbit, placing the over 2,300 kg payload into a precise orbit using a GSLV rocket. Friday's launch marked the space agency's maiden success for the year 2026. The EOS-05 satellite was successfully placed in the intended sub-geosynchronous transfer orbit, about 18 minutes after it lifted off from the spaceport here, ISRO announced. While several earth observation satellites operate from low earth orbit (LEO), the EOS-5 satellite is set to hover at an altitude of roughly 36,000 km above earth, which is the geosynchronous orbit and at that level, the satellite will match Earth's rotational speed. At over 2,300 kg, this is the heaviest satellite ever to be carried by a GSLV and the satellite was perfectly ahead in its trajectory. "The eye in the sky," as one of the senior scientists involved in the mission described the satellite, is set to provide .

LVM3-M6 success boosts confidence in Gaganyaan programme: Isro chief

The successful launch of the Bluebird Block-2 satellite onboard an LVM3-M6 rocket has enhanced confidence in India's human spaceflight programme, Gaganyaan, ISRO Chairman V Narayanan said on Wednesday. He emphasised the critical role of launch vehicle LVM3, which would be used for the ambitious Gaganyaan programme, the mission to send Indian astronauts to orbit and bring them safely back to earth. Addressing reporters, Narayanan said, "Today, it is a very important mission for us. Because you all know this is the vehicle which is human-rated and identified for the Gaganyaan programme for India. So, with 9 consecutive successful LVM3 launches, it improves our confidence in the Gaganyaan programme. It is also the mandated requirement." Listing highlights of the LVM3-Bluebird Block-2 mission, he said, the placing of Bluebird-Block-2 satellite precisely into the intended orbit is the best accuracy so far achieved ever on Indian soil. According to him, the LVM3 vehicle demonstrated one

NISAR satellite deploys 12-metre diameter antenna, enters science phase

NASA-ISRO Synthetic Aperture Radar (NISAR) satellite launched onboard GSLV-F16 on July 30 this year successfully deployed 12-metre diameter antenna reflector and entered science phase, ISRO said on Friday. The antenna plays a key role for both ISRO's S-Band and NASA's L-Band Synthetic Aperture Radar (SAR) payload, it said. "The first image of S-Band SAR acquired on August 19, 2025, captures the fertile Godavari River Delta in Andhra Pradesh, India. Various vegetation classes like mangroves, agriculture, arecanut plantations, aquaculture fields, etc. are clearly seen in the image. The image highlights NISAR's S-Band SAR ability to map river deltas and agricultural landscapes with precision," ISRO said in a statement. On the 100th day of NISAR in orbit, the S-SAR images were released to the public by the Chairman, ISRO. With this, the commencement of the science phase has also been announced, it said. The antenna was launched in a stowed condition on a 9-metre-long boom, which was ..

Isro developing 40-storey rocket to launch 75-tonne satellite: Narayanan

ISRO Chairman V Narayanan on Tuesday said the space agency has been working on a rocket as high as a 40-storey building to place 75,000 kg satellite in low earth orbit. Delivering the convocation address of Osmania University here, Narayanan said this year, the space agency has lined up with projects such as NAVIC (Navigation with India Constellation system) satellite and the N1 rocket, besides placing a 6,500 kg communication satellite of the USA into orbit using Indian rockets. "You know, what is the capacity of the rocket? The first launcher, (Dr APJ) Abdul Kalam ji, which he built was a 17 tonne lift-off mass, capable of placing 35 kg in low earth orbit. Today, we are conceiving a rocket to place 75,000 kg in low earth orbit. The rocket is of 40-storey building height," he said. ISRO has planned to launch Technology Demonstration Satellite (TDS) and GSAT-7R, a Indian military communication satellite, specifically designed for the Indian Navy to replace the existing GSAT-7 ...

Isro successfully conducts third hot test of semicryogenic engine

The Indian Space Research Organisation on Monday achieved a significant milestone with the successful completion of the third hot test of the Power Head Test Article (PHTA) at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu. The test is part of a crucial series of evaluations to validate the performance of India's upcoming semicryogenic engine, ISRO said. This marks the third in a series of hot tests undertaken by ISRO for the PHTA. According to ISRO, the test, conducted on May 28, was aimed at validating the engine's ignition and start-up sequence while optimising the process for integrated engine performance. During the three-second trial, the engine was ignited successfully and operated up to 60 per cent of its rated power level, exhibiting stable and controlled performance throughout. ISRO began this series of performance evaluations in March 2025, focusing on critical components such as low- and high-pressure turbo-pumps, the pre-burner, start-up system, and various .

Isro successfully carries out vacuum ignition trial of cryogenic engine

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 NVS-02 satellite suffers setback after thrusters fail to fire

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
