India tests scramjet engine for over 1,000 seconds in hypersonic technology leap
In a significant step towards the development of the next-generation station hypersonic missiles, India has successfully carried out a ground test of the Scramjet engine for more than 1,000 seconds.Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of the Defence Research and Development Organisation (DRDO) achieved this significant milestone in the field of Hypersonic Weapon Technology.DRDL conducted long-duration Active Cooled Scramjet Subscale Combustor ground testing for more than 1000 seconds duration at the newly built state-of-the-art Scramjet Connect Test Facility (SCPT) in Hyderabad on April 25, 2025.The ground test conducted is in continuation of an earlier test reported for 120 seconds in January 2025. "With today's successful test, the system will soon be ready for full-scale flight-worthy combustor testing," DRDO said.advertisement
The Hypersonic Cruise Missile (HCM) is a class of weapon capable of sustained flight at speeds exceeding five times the speed of sound (>6,100 kmph), powered by an air-breathing engine. Supersonic combustion in air-breathing propulsion systems plays a crucial role in maintaining long-duration cruise conditions.The recent test successfully validated the design of a long-duration scramjet combustor and the associated test facility. This achievement is the result of a collaborative effort involving DRDO laboratories, industry partners, and academic institutions, and marks a significant milestone in advancing India's Hypersonic Cruise Missile Development Programme, according to DRDO.Defence Minister Rajnath Singh complimented DRDO, industry partners and academia for the achievement and stated that today's success reflects India's strong commitment to realising critical Hypersonic Weapon Technologies for the nation.Secretary, Department of Defence R&D and Chairman DRDO Dr Samir V Kamat congratulated Director General (MSS) U Raja Babu, Director DRDL Dr GA Srinivasa Murthy and the whole team for demonstrating supersonic combustion for more than 1000 seconds involving cutting-edge technologies.advertisement

Mysuru's DFRL understands gravity of astronauts' food cravings
Mysuru: The launch of the Axiom-4 mission carrying Indian astronaut Shubhanshu Shukla and three others to the International Space Station (ISS) may have been postponed. .But Mysuru-based Defence Food Research Laboratory (DFRL), under DRDO, has prepared a variety of food items that were to have been carried as part of the Indian Space Research Organisation (Isro) and the Defence Research and Development Organisation (DRDO) have developed an Indian menu for space after years of with scientific instruments and personal mementoes, Shubhanshu would have carried Mysuru-made food to the ISS in the Axiom-4 mission that has now been put off. .SpaceX's Axiom 4 mission postponed again, India's Shubhanshu Shukla's maiden journey to ISS officer Madhukar confirmed to DH that the astronaut was to carry a few Indian foods for the mission, including mango nectar (aam ras), carrot halwa (gajar ka halwa), moong dal halwa and a few rice human spaceflight programme director had disclosed this in a meeting held recently in Bengaluru..'As per the memorandum of understanding (MoU) between Isro and DRDO, we are not allowed to give out more details,' Madhukar said..'We are excited that the food products prepared here will be tasted by astronauts of the ISS mission. It is an effort to make the Indian astronaut's space mission memorable,' he cookies and candies are packed for space trips. NASA's space food systems laboratory produces freeze-dried this time the Indian astronaut will have Indian food on DFRL has developed a range of ready-to-eat and semi-hydrated Indian dishes for the mission, tailored for zero gravity. This includes parathas, vegetable biryani, rice and dal, sambar, rajma, khichdi and food has been designed in such a way that it is lightweight, low-volume and easy-to-consume wholesome food. The astronaut just has to add water to the items and warm it before eating it in tickled Rakesh Sharma's taste buds DFRL was established in Mysuru in 1961 to cater to the needs of the Indian Army, Navy, Air Force, and paramilitary forces. It aims to design light-weight food with a longer shelf life under varied climatic had also prepared and packed food for Rakesh Sharma four decades ago.

Disney, Universal sue AI firm Midjourney for copyright infringement
Last Updated: New York, Jun 11 (AP) Disney and Universal have filed a copyright lawsuit against popular artificial intelligence image-generator Midjourney on Wednesday, marking the first time major Hollywood companies have enter the legal battle over generative AI. Filed in federal district court in Los Angeles, the complaint claims Midjourney pirated the libraries of the two Hollywood studios to generate and distribute 'endless unauthorized copies" of their famed characters, such as Darth Vader from Star Wars and the Minions from Despicable Me. 'Midjourney is the quintessential copyright free-rider and a bottomless pit of plagiarism. Piracy is piracy, and whether an infringing image or video is made with AI or another technology does not make it any less infringing," the companies state in the complaint. The studios also claimed the San Francisco-based AI company ignored their requests to stop infringing on their copyrighted works and to take technological measures to halt such image generation. Midjourney could not immediately be reached for comment. The small startup is one of a crop of research labs enabling people to experiment with AI-generated visuals and text. Major AI developers don't typically disclose their data sources but have argued that taking troves of publicly accessible online text, images and other media to train their AI systems is protected by the 'fair use" doctrine of American copyright law.

Samsung assembled more mobile phones in India than Apple last year
Korean firm makes more phones across most segments and has higher volumes: S&P report Surajeet Das Gupta New Delhi Listen to This Article Samsung's global volume share of final assembling of smartphones in India might not get the same focus as that of Apple Inc because of the latter's aggressive export strategy and higher average selling price leading to higher value. But in terms of volume, the reality is that Samsung is much higher than its US rival. A research by S&P Global shows that Samsung's share of global final assembly volume of smartphones in India in 2024 was at 25 per cent compared to only 15 per cent of the Cupertino-based Apple Inc in the same period. For Samsung, its biggest exposure
