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 .

ISRO to launch 2 missions under Gaganyaan programme in 2023: Jitendra Singh

The Indian Space and Research Organisation (ISRO) will launch two initial missions later this year under the 'Gaganyaan' programme followed by country's maiden human space-flight mission in 2024, Union Minister Jitendra Singh has said. The second part of the 2023 mission will carry a female robot "Vyommitra" to space, the science and technology minister said. In an interview with PTI, Singh said these missions were envisaged to be launched in the 75th year of Indian independence, but due to the emergence of COVID-19 these programmes were delayed by two to three years. "The then ongoing training of our astronauts in Russia was stopped midway due to the pandemic," he said, adding that they were sent back to complete their training once the situation subsided. "In the second half of this year, two initial missions will be sent under the Gaganyaan programme. One mission will be completely unmanned and a female robot named 'Vyommitra' will be sent in the second one," Singh said. These

Chandrayaan-3 tested successfully, likely to be launched in June: ISRO

Indian Space Research Organisation (ISRO) on Sunday said that the 'Chandrayaan-3' lander has "successfully" underwent the Electro-Magnetic Interference/Electro-Magnetic Compatibility (EMI/EMC) test between January 31 and February 2 at the U R Rao Satellite Centre here. The EMI/EMC test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels, ISRO said. It said, this test is a major milestone in the realisation of the satellites. According to the space agency, Chandrayaan-3 interplanetary mission has three major modules. They are - the Propulsion module, Lander module and Rover, and the mission's complexity calls for establishing radio-frequency (RF) communication links between the modules. "During the Chandrayaan-3 lander EMI/EC test, Launcher compatibility, Antenna Polarization of all RF systems, Standalone auto compatibility tests for orbital and powere

Group of lunar meteorites throw light on origin of basalts on Moon: ISRO

A team of scientists from Ahmedabad-based Physical Research Laboratory (PRL), the United States and Japan has found a unique group of ancient lunar basaltic meteorites, suggesting a new scenario for the origin of lunar basalts, according to ISRO. PRL, which is a unit of the Department of Space, carries out fundamental research in select areas of physics, space and atmospheric sciences, astronomy, astrophysics and solar physics, and planetary and geo-Sciences. The Indian Space Research Organisation (ISRO) issued a statement on Thursday saying the Moon's dark regions that are visible to the naked eye, known as the 'mare', are remnants of a violent history of the Solar System. There are no records, though, of these frenzied events on Earth. The Moon, having changed very little over billions of years, provides us a window to ponder over the past. The large mare regions on the near side of the Moon, that can be seen from Earth, mainly consists of basalts comprising volcanic rocks, it ...
