ISRO cancels semi-cryogenic engine test after sudden pressure, speed spike

The Indian Space Research Organisation terminated the first hot test on an intermediate configuration of the semi-cryogenic engine following an unanticipated spike in the turbine pressure and subsequent loss of turbine speed. The July 1 test at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, was conducted towards developing a 2,000 kN (Kilonewton) thrust semi-cryogenic engine, known as power head test article (PHTA), to power the booster stages of future launch vehicles, the Bengaluru-headquartered national space agency said in a statement on Monday. The objective of the test was to validate the integrated performance of the critical subsystems such as the gas generator, turbo pumps, pre-burner and control components by carrying out a hot-firing for a short duration of 4.5 seconds, it said. "The ignition and generation of hot gas within the pre-burner chamber that drives the main turbine to drive the fuel and oxidiser pumps was focussed," the statement from ISRO said. "Th

Ahead of Chandrayaan-3 mission, Sriharikota to witness a unique 'launch'

Just a few hours ahead of India's much-awaited Moon mission Chandrayaan-3 takes off next week, the rocket launchpad at Satish Dhawan Space Centre (SDSC) in Sriharikota will witness a unique launch. Not the launch of a rocket but of a book. It may sound strange but the book named 'Prism: The Ancestral Abode of Rainbow', a collection of science articles, will be released at the SDSC-SHAR from where the LVM-III would lift off carrying Chandrayaan-3 to the Moon on July 13. Authored by national award-winning filmmaker-writer Vinod Mankara, 'Prism' is likely the first book to be released from a rocket launchpad anywhere in the world. Mankara is the maker of 'Yanam', a science-Sanskrit documentary on India's historic Mars Orbiter Mission 'Mangalyaan'. A collection of 50 essays in Malayalam, the book comprises articles from various streams of science including space science, astronomy, biology, anthropology, mathematics and so on. ISRO Chairman S Somanath will launch the book by handing

1st abort mission of 'Gaganyaan' to be conducted in August-end: Isro chief

The first abort mission for India's maiden human spaceflight 'Gaganyaan' would be conducted at the end of August this year, while the unmanned mission to orbit would take place next year, Chairman of the Indian Space Research Organisation (ISRO), S Somanath, said here on Thursday. Talking to media-persons on the sidelines of an event at the Physical Research Laboratory (PRL) here, he said the test vehicle is ready at Sriharikota and the assembly work of the crew module and crew escape system has also begun. "For Gaganyaan, the first and foremost thing is that the abort mission has to be done. For that, we have made a new rocket called a test vehicle, which is ready at Sriharikota. Assemblies of the crew module and crew escape system are just getting ready," Somanath told reporters when asked about the latest update on Gaganyaan. "So I am informed that this month-end it will go for a fully functional testing, vibration testing, etc. So we are hoping that in August-end or so we will .

India to sign Artemis Accords, send joint mission to ISS, says White House

India has decided to join the Artemis Accords, which brings like-minded countries together on civil space exploration, and NASA and ISRO have agreed to a joint mission to the International Space Station in 2024, the White House said Thursday. On space, we will be able to announce that India is signing the Artemis Accords, which advance a common vision for space exploration for the benefit of all humankind, a senior administration official said hours before the meeting between Prime Minister Narendra Modi and President Joe Biden in the Oval Office. Grounded in the Outer Space Treaty of 1967 (OST), the Artemis Accords are a non-binding set of principles designed to guide civil space exploration and use in the 21st century. It is an American-led effort to return humans to the moon by 2025, with the ultimate goal of expanding space exploration to Mars and beyond. The official said that NASA and the ISRO are developing a strategic framework for human spaceflight cooperation this year. I

Chandrayaan-3 to be launched between July 12 and 19, says ISRO chief

If all the tests go smoothly, Chandrayaan-3, India's ambitious plan to land on the surface of the Moon, will be launched between July 12 and 19, Indian Space Research Organisation (ISRO) Chairman S Somanath said here on Monday. Speaking to the media after inaugurating a one-day workshop and space exhibition at Kothavara St Xavier's College organised by ISRO, Somanath said that the Chandrayaan has already reached the launch pad in Satish Dhawan Space Centre, Sriharikota, from U R Rao Satellite Centre. "The final preparations are going on. It will be completed by the end of this month. At the same time, the rocket, LVM-3, is going to be used for this launch. Its assembly is going on. All parts for its assembly have reached Sriharikota," Somanath said. He said the rocket assembly will also be completed by the end of this month and then there is a process to integrate Chandrayaan-3 with the rocket. He said that too would be done in the last week of June and many tests will follow. "The

Announcement coming soon on 'Hava' rocket testing facility: ISRO Chief

Indian Space Research Organisation chairman S Somanath on Thursday said there will be an announcement soon about the space agency's testing facility with regard to the hypersonic air breathing vehicle 'Hava'. The space scientist, however, emphasises that ISRO was not focused on air breathing technology because it wants to deal more with space. Air-breathing engines are those that take in air from its surroundings in order to burn fuel, such as jet engines. It is therefore not suitable for space travel as there is no air/atmosphere in space. "We are also developing a new rocket 'Hava' to fly at a hypersonic speed for 200-plus seconds. You will also hear some announcements soon about our testing plant with the new fuel for air breathing," Somanath told reporters here. 'HAVA' stands for Hypersonic Air Breathing Vehicle with Air Integration System. Replying to a query on the progress made on air breathing technology, Somanath said ISRO is looking at it not as an immediate input for an

ISRO chief hails role of Sanskrit in India becoming knowledge society

India was a knowledge society since Vedic times involving Maths, medicine, metaphysics, astronomy etc written in Sanskrit, but all such learning came back to the country several thousand years later as "discoveries by Western scientists", Indian Space Research Organisation chairman S Somnath has said. Addressing the fourth convocation ceremony of the Maharishi Panini Sanskrit and Vedic University here on Wednesday, Somnath said Sanskrit was one of the most ancient languages of the world with its repertoire including poetry, logic, grammar, philosophy, science, technology, maths and other allied subjects. "Surya Sidhanta, the very first book I came across in Sanskrit talks about the domain I am familiar with. This book specifically talks about solar system, how planets move around the sun, periodicity of this movement, timescales etc," he said. "All this knowledge travelled from here, reached the Arabs, then went to Europe and thousands of years later came back to us as discoveries o

ISRO to launch navigation satellite on GSLV from Sriharikota on May 29

The Indian Space Research Organisation (ISRO) will launch navigation satellite 'NVS-01' onboard its Geosynchronous Satellite Launch Vehicle (GSLV) from Sriharikota in Andhra Pradesh on May 29. The mission is designed to deploy the NVS-01 navigation satellite, weighing 2,232 kilograms, into a Geosynchronous Transfer Orbit (GTO). "The launch of the GSLV-F12/NVS-01 mission is scheduled on Monday, May 29 at 10:42 hours IST from the second launch pad at Satish Dhawan Space Centre in Sriharikota," the Bengaluru-headquartered national space agency said in a release on Monday. Subsequent orbit raising manoeuvres will be used for taking the satellite to the intended orbit, the space agency said. NVS-01 is the first of the second-generation satellites envisaged for the Navigation with Indian Constellation (NavIC) services, it said. NavIC is India's own indigenous satellite navigation system similar to the prominent Global Positioning System (GPS), which belongs to the United States. Accord
