The ISRO chief said it was important to have a connection between scientific institutions across the world and ISRO in building complex missions. He cited the example of the TRISHNA mission, designed to observe the earth's surface in the thermal infrared domain, which has been developed by ISRO and its French counterpart CNES. "We are also discussing a possible mission to the moon with JASA (Japan Aerospace Exploration Agency) where the land rover

Chandrayaan 3, Aditya L1 will be launched in middle of 2023: ISRO chief

Indian Space Research Organisation (ISRO) chairman S Somanath on Wednesday said the launch of Chandrayaan-3, India's third lunar mission, and the first solar mission Aditya L1 will possibly happen by the middle of 2023. He was delivering the inaugural talk on "Indian Capabilities for Space and Planetary Exploration" at the 4th Indian Planetary Science Conference organised at Physical Research Laboratory (PRL) here. "The Chandrayaan-3 craft is fully ready. It is fully integrated. Of course, there is some correction work being done, and we are building a lot of confidence in the mission through lots of simulations and tests, etc. And possibly the launch can take place by the middle of this year," Somanath said. He said Aditya-L1, India's first solar mission, is going to be "a very unique solar observation capability for which instruments have already been delivered, and ISRO is in the process of integrating them in the satellite. "I am also eagerly waiting for this (Aditya-L1) launch

Chandrayaan-3 spacecraft capable of handling harsh launch conditions: Isro

India's national space agency ISRO announced on Thursday that it has reached a new milesone in the pursuit of a soft landing on the Moon, with the Chandrayaan-3 spacecraft having successfully completed "the essential tests" that validated its capability to withstand the harsh vibration and acoustic environment that the spacecraft would face during its launch. The tests were conducted during the first week of March in the facilities located at U R Rao Satellite Centre here, the Bengaluru-headquartered national space agency said in a statement today. "These tests are an essential part of the qualification and acceptance process for any spacecraft," ISRO said, adding that they were particularly challenging, considering the fact that the Chandrayaan-3 spacecraft is a composite of three modules -- Propulsion Module, Lander Module and the Rover module. The vibration and acoustic tests carried out on the integrated spacecraft has provided sufficient confidence about its structural integrit

ISRO set to launch 36 low earth orbit satellites for OneWeb on March 26

ISRO is all set to launch 36 low earth orbit satellites for UK-based OneWeb later this month that will complete its first-generation constellation for providing internet through space across the world. "Exciting news from India as we confirm the encapsulation of our 36 satellites ahead of OneWebLaunch18; our final launch which will complete our Gen 1 constellation," OneWeb said on Twitter. "Target date is March 26th Go OneWeb," Massimiliano Ladovaz, Chief Technology Officer of OneWeb, tweeted. The private satellite communications company has India's Bharti Enterprises as a major investor and shareholder. The 36 satellites of OneWeb reached India on February 16 from the satellite manufacturing unit in Florida for integration with the Launch Vehicle Mark III. In October last year, the ISRO successfully launched the first batch of 36 satellites by OneWeb from the Satish Dhawan Space Centre in Sriharikota, marking the entry of LVM-3 into the global commercial launch service ...

ISRO carries out controlled re-entry experiment of decommissioned satellite

The Indian Space Research Organisation said it successfully carried out an "extremely challenging" controlled re-entry experiment of the decommissioned orbiting Megha-Tropiques-1 (MT-1) satellite on Tuesday. "The satellite re-entered the Earth's atmosphere and would have disintegrated over the Pacific Ocean", the Bengaluru-headquartered national space agency said on Twitter. The final impact region estimated is in the deep Pacific Ocean within the expected latitude and longitude boundaries, an ISRO statement said. The low Earth satellite was launched on October 12, 2011, as a joint satellite venture of ISRO and the French space agency, CNES for tropical weather and climate studies. Since August 2022, the satellite's perigee was progressively lowered through a series of 20 manoeuvres spending about 120 kg of fuel. Multiple manoeuvres including the final de-boost strategy were designed after taking into consideration several constraints, including visibility of the re-entry trace ov

Isro conducts parachute tests for Gaganyaan human space flight mission

The Indian Space Research Organisation has conducted tests simulating the clustered deployment of parachutes as part of preparations for the Gaganyaan human space flight mission. ISRO carried out the 'Rail Track Rocket Sled' deployment tests of the Gaganyaan Pilot and Apex Cover Separation (ACS) parachutes in cluster configurations at the Terminal Ballistics Research Laboratory (TBRL), Chandigarh. The first test simulated the clustered deployment of two pilot parachutes -- one parachute was subjected to a minimum angle with respect to flow conditions and the second to a maximum angle with respect to flow, the national space agency headquartered here said. "These pilot parachutes are used in the Gaganyaan mission to extract and deploy the main parachutes independently," an ISRO statement said. The second test simulated the clustered deployment of two ACS parachutes under maximum dynamic pressure conditions. The test also simulated clustered deployment at a 90-degree angle of attack

ISRO gears up for taxing experiment of controlled reentry of aged satellite

The Indian Space Research Organisation (ISRO) is gearing up for an "extremely challenging" experiment of controlled re-entry of a decommissioned orbiting satellite on Tuesday. The low Earth satellite, Megha-Tropiques-1 (MT1), was launched on October 12, 2011, as a joint satellite venture of ISRO and the French space agency, CNES for tropical weather and climate studies. An uninhabited area in the Pacific Ocean between 5S to 14S latitude and 119W to 100W longitude was identified as the targeted re-entry zone for MT1, weighing about 1000 kg. About 125 kg on-board fuel remained unutilised at its end-of-mission that could pose risks for accidental break-up, an ISRO statement noted. This left-over fuel was estimated to be sufficient to achieve a fully controlled atmospheric re-entry to impact the uninhabited location in the Pacific Ocean. Controlled re-entries involve deorbiting to very low altitudes to ensure impact occurs within a targeted safe zone. Usually, large satellites/rocket

ISRO successfully conducts key rocket engine test for Chandrayaan-3

The flight acceptance hot test of the CE-20 cryogenic engine that will power the cryogenic upper stage of the launch vehicle for the Chandrayaan-3 mission was successfully conducted, according to the Indian Space Research Organisation. The hot test was carried out for a planned duration of 25 seconds at the High Altitude Test Facility of the ISRO Propulsion Complex at Mahendragiri in Tamil Nadu on February 24, the Bengaluru-headquartered national space agency said. "All the propulsion parameters during the test were found satisfactory and closely matched with predictions," an ISRO statement said on Monday. The cryogenic engine will be further integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully-integrated flight cryogenic stage, ISRO said. Earlier this year, Chandrayaan-3 lander successfully underwent EMI/EMC test at U R Rao Satellite Centre here. EMI-EMC (Electro - Magnetic Interference/ Electro - Magnetic Compatibility) test is .
