PSLV-C61 mission could not be accomplished: ISRO Chief

ISRO on Sunday (May 18, 2025) could not accomplish the launch of an Earth observation satellite onboard a PSLV-C61 rocket after it encountered some anomaly in its third stage, the space agency's Chairman V. Narayanan said.
ISRO's trusted Polar Satellite Launch Vehicle (PSLV) is a 4-stage rocket and the first two stages were normal, he said.
'Today we targeted the 101st launch from Sriharikota, the PSLVC61 EOS-09 mission. The PSLV is a four-stage vehicle and up to the second stage, the performance was 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,' Mr. Narayanan said.
Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be accomplished. — ISRO (@isro) May 18, 2025
EOS-09 is a repeat satellite similar to EOS-04 launched in 2022 that has been designed with the mission objective to ensure remote sensing data for the user community engaged in operational applications and to improve the frequency of observation.
The mission's payload, a Synthetic Aperture Radar (SAR) which is inside the satellite is capable of providing images for various earth observation applications under all-weather conditions day and night.
This all-weather, round-the-clock, imaging is vital for applications, ranging from agriculture and forestry monitoring to disaster management, urban planning and national security.

Sparking Dreams: India Plans 100 Space Labs For Students From Tribal Communities

Last Updated: The initiative led by the Ministry of Tribal Affairs aims to inspire the next-generation of space explorers studying in 477 Eklavya Model Residential Schools across 26 states & UTs In a push to inspire the next generation of space explorers, the government will set up 100 space laboratories in Eklavya Model Residential Schools across India. First established in 1997-98 to provide quality education to tribal communities in remote areas, these fully-residential schools will now aim to spark children's ambition to reach for the stars. The initiative will be fully-funded by Corporate Social Responsibility (CSR) donors, and is set to benefit as many as 477 schools. The states expected to see the highest rollout include Chhattisgarh (75), Madhya Pradesh (63), Jharkhand (53), Odisha (47), Gujarat (38), and Maharashtra (37), and Rajasthan (30). The laboratories will be equipped with a star-tracker telescope, demonstrative models of ISRO's launch vehicles, including LVM Mk3, PSLV, as well as static models of earth observation satellites, GSAT, IRNSS, and space science books for students keen to read. The aim is to provide an interactive, hands-on learning environment to inspire students to explore careers in space and STEM fields. The National Scheduled Tribes Finance and Development Corporation (NSTFDC) under the Ministry of Tribal Affairs issued the tender on June 20, inviting agencies to submit their bids by July 10 to implement the project across India. Importantly, the laboratories will be established only through ISRO-recognised 'space-tutor' organisations to ensure quality and accuracy. 'The target is to enhance the quality of education by bridging the educational gaps and open new avenues for tribal youth in the fields of space science, technology, engineering, and math (STEM), through these Space Labs in Eklavya Model Residential School (EMRS) run by National Education Society for Tribal Students (NESTS), a society under Ministry of Tribal Affairs across 26 states and UTs," said the ministry. The implementing agencies, which must be at least five years old, will handle the procurement in line with the norms and also support NSTFDC in mobilising additional CSR support to expand the initiative. They will also be responsible for donor branding and outreach, including short videos, coffee table books and other promotional content. This comes as India prepares to launch some of its ambitious space missions, with ISRO's first-ever human spaceflight Gaganyaan scheduled to take off in 2027. After successfully landing near the South Pole of the Moon in 2023, the space agency is now working towards another Chandrayaan mission to collect and bring back lunar samples. Also in the pipeline is Bharatiya Antariksh Station to be set up by 2035. Gaganyaan astronaut designate Group Captain Shubhanshu Shukla, who has been selected to fly to the International Space Station as part of Axiom Mission-4, will also be interacting with students from various schools from space once the spacecraft docks into the ISS. The mission spearheaded by NASA, SpaceX and Axiom Space is currently without a launch date after being postponed multiple times. First Published: June 23, 2025, 09:32 IST

Putting man in space is India's next giant leap: AS Kiran Kumar

Mangaluru: The former chairman of the Indian Space Research Organisation (Isro), AS Kiran Kumar, stated that the space agency aims to establish India's own space station by 2035. Tired of too many ads? go ad free now He was speaking during an event titled 'Igniting the future: Isro's legacy and beyond' organised by the Ramakrishna Mission Mangaluru and Samatha Mahila Balaga at the Ramakrishna Math hall on Sunday. "Visionaries like Vikram Sarabhai and Homi J Bhabha laid the foundation for Isro. Today, Isro plays a pivotal role in India's development. While other countries have used space activities for military purposes, India initially focused on non-military objectives like finding solutions to its problems such as weather monitoring, communication, broadcasting, and navigation. After centuries of foreign rule, providing basic necessities like shelter and housing for all citizens was a major challenge in India. In such a context, many naturally questioned whether priority should be given to the development of space technology," he explained. "By the time we reach 100 years of Independence, and when we aspire to reach the topmost, we also need to build capacity and capability. Putting man in space is one such capability. Originally, the plan was, by the 75th year of Independence, we should have put humans into orbit and brought them back. However, because of Covid-19 and other reasons, it got delayed," he said. On the Gaganyaan programme, he said probably within a year or two, we will have Indian astronauts going around the orbit. "The ambitious — to send a human to space — is India's next giant leap. The Gaganyaan programme requires large vehicles to be human-rated. Tired of too many ads? go ad free now Once we achieve this mission, we will become the fourth country in the world, beyond America, Russia, and China. It is an essential requirement because the world recognises only those who demonstrate capability," he said. "Apart from launching its own satellites, India has successfully launched over 450 satellites from more than 34 countries. Through landmark missions like Chandrayaan, Mangalyaan, and Aditya, India's capabilities have gained global recognition," he noted. He called upon students to engage in space research and become scientists to contribute to the nation's growth. Swami Jitakamanandaji, secretary of Ramakrishna Math, Mangaluru, graced the event. The programme was inaugurated by Sumana Ghate, general manager, Karnataka Bank. The session was presided over by Katyayini Bhide, president of Samatha Mahila Balaga, Mangaluru. MM Nayak, former director of Isro's INSAT programme, Vijayalakshmi Rao, honorary president of Samatha Mahila Balaga, and MLC Manjunath Bhandary were present. 'Space on Wheels' exhibition A mobile scientific exhibition titled 'Space on Wheels', curated by UR Rao Satellite Centre, Bengaluru, was also held. A specially designed exhibition bus arrived from Bengaluru. The exhibition, which presented the history, achievements, and future vision of Isro, attracted more than 1,000 students from various schools and colleges.

Work hard to enable India to take humans to moon by 2040: Former ISRO Chief tells youth

Former ISRO Chief and Space Commission member A.S. Kiran Kumar on Sunday asked youth to work hard to make India a space capable nation and enable the country to take humans to moon by 2040. Speaking on the topic 'Igniting the future: ISRO's legacy and beyond', at the Ramakrishna Mutt in Mangaluru on Sunday, Mr. Kumar said the nation, which is moving towards becoming world's largest economy, cannot ignore space economy. The space economy is a trillion dollar economy. Space tourism and space adventure provided tremendous opportunity. Mr. Kumar said, 'Unless our capability in space mission is demonstrated other nations will not take note of India. Youngsters should become leaders and showcase our capability in space science.' Works are on towards having country's own space station by 2035. 'By 2040 we have to take humans to moon and bring them back,' the former ISRO chief said. The government is allowing more people to work in space science. Private entities and consortium of firms are being allowed to launch their satellites. Since the start of the space programme for non-military purpose in October 1957, ISRO has leapfrogged in space technology to indigenously develop different launch pads and launch a number of satellites, he said. 'NavIC, the country's own satellite-based navigation system developed by ISRO, is helping fishermen to navigate through sea in a safe way and find fish. With the feed from satellites and other information, there is advance information about cyclones, which has helped government to evacuate and save lives of people from places that are likely to be affected,' he said. The feed from satellites is also helping forecast crop yield. The use of satellites in hitting precise targets in enemy nation was demonstrated in the recent Operation Sindoor, he said. The youth, he said, are left with lot of problems to solve. 'You have tremendous capability. Rise and lead the country to regain the glory as the place of harmony and peace,' he said.
