ISRO says its earth observation satellite mission could not be accomplished
The Indian Space Research Organisation on Sunday said that its PSLV-C61 earth observation satellite mission could not be accomplished.
The mission marked the 63rd flight of the Polar Satellite Launch Vehicle and the 27th using the PSLV-XL configuration. The PSLV-C61 was set to place the EOS-09 earth observation satellite into a Sun Synchronous Polar Orbit, meaning that the satellite would pass over a given area on earth at the same time every day.
The satellite carried a Synthetic Aperture Radar payload, which could provide images of the earth in all weather conditions.
However, minutes after the PSLV-C61 with the satellite lifted off from the Satish Dhawan Space Centre in Sriharikota at 5.59 am, the space agency said that the mission could not be accomplished due to an 'observation'.
'Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage,' the space agency said in a statement. 'Due to an observation in 3rd stage, the mission could not be accomplished.'
'Today from Sriharikota the PSLV-C61/EOS-09 mission was targeted,' ISRO chairperson V Narayanan said. 'The PSLV is a four stage vehicle and the second stage performance was quite normal. The third stage motor started perfectly but during the functioning of the third stage, we are seeing an observation and the mission could not be accomplished.'
He said more details would be provided after an analysis.
The PSLV has failed on only two earlier occasions – once during its inaugural flight in 1993 and another time in 2017, when the C-39 mission had been unsuccessful, The Hindu reported.

Rediscovery of the Losgna genus in India: a new species of parasitic wasp discovered in Chandigarh, named - ‘Losgna Occidentalis'
At a time when habitat loss and climate change threaten countless species, the discovery of a new species of parasitic wasp - named 'Losgna Occidentalis' from Chandigarh has drawn attention to the unexplored richness of India's biodiversity. A recent study published in Zootaxa, a peer-reviewed scientific journal for animal taxonomists, titled - 'Rediscovery and description of a new species of Losgna (Cameron 1903): reviving a forgotten ichneumonid genus (Darwin wasps) in India' - points out the rediscovery of the Losgna genus in India, after close to six decades, and describes 'a new species collected from an urban dry scrub forest in Chandigarh.' 'The solitary Losgna (wasp) specimen was collected from a windowsill in Chandigarh, during winter 2023–24. This locality marks the first time any new insect species has been formally described from Chandigarh. The specimen belongs to a parasitic wasp (family Ichneumonidae), a group known for laying eggs inside or on other arthropod hosts. Prior to this discovery, Losgna had not been recorded in India since Heinrich's 1965 monograph. No records, specimens or published literature on Losgna existed in any Indian institution after 1965. It appeared that the genus had vanished entirely from its once‐documented range in northeast India until we found this new specimen in Chandigarh,' Karmannye Chaudhary, who led the study, a researcher in bird ecology and insect taxonomy at the Queen Mary University of London, told The Hindu. 'We named the new species 'Losgna occidentalis' because it represents the westernmost known occurrence of the genus: prior records came exclusively from tropical forests of eastern India and adjacent regions of Southeast Asia. 'Occidentalis' signifies this western extension,' he said. Pointing out that the only existing specimens of any Losgna species are those preserved at the Natural History Museum, London, The Hope Collection, Oxford University and the Zoologische Staatssammlung München (ZSM), Munich - all dating from the British era, Mr. Chaudhary said, 'No other collections -Indian or international - were found to hold Losgna material between 1965 and our study.' 'As a researcher of Hymenoptera, I'm thrilled by the discovery of Losgna occidentalis. It highlights the importance of solid taxonomic work and shows how young people, and even citizens, can find new species in their own backyards. This project also exemplifies valuable international collaboration between institutions like the NHM and Oxford, which is vital given how underfunded and poorly coordinated taxonomy has become. Hymenoptera are crucial as pollinators and biological control agents, so identifying and describing new species is essential for understanding and conserving our ecosystems. I hope this discovery inspires others to explore local habitats, collect specimens responsibly, and collaborate across borders to document India's hidden biodiversity,' said Ritesh Kumar Gautam, scientist at Wildlife Institute of India, Dehradun, Uttarakhand.

Indian astronaut Shubhanshu Shukla's launch, arrival details at ISS out by NASA; Check how to stream, date, time, other key details here
NASA , Axiom Space, and SpaceX are targeting 8:22 a.m. EDT, Tuesday, June 10, for launch of the fourth private astronaut mission to the International Space Station , Axiom Mission 4 , according to a recent press statement of US space agency. For India, 8:22 a.m. EDT translates to 5:52 pm IST. The mission will lift off from Launch Complex 39A at NASA's Kennedy Space Center in Florida. The crew will travel to the orbiting laboratory on a new SpaceX Dragon spacecraft after launching on the company's Falcon 9 rocket. The targeted docking time is approximately 12:30 p.m., Wednesday, June 11. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 2024-2025 Models: Small SUVs Are Turning Heads (Take A Look) FrequentSearches | Search Ads Learn More Undo How to stream the launch and arrival activities?

Astronaut Shubhanshu Shukla blasts off into space next week as the first Indian to join the International Space Station (ISS), bearing with him New Delhi's dreams of its own manned space flight. An airforce fighter pilot, 39-year-old Shukla is joining a four-crew mission launching from the United States with private company Axiom Space, aboard a SpaceX Crew Dragon capsule. He will become the first Indian to join the ISS, and only the second ever in orbit -- an achievement that the world's most populous nation hopes will be a stepping stone for its own human flight.
