Govt to shortly notify rules for mandatory use of IST: Pralhad Joshi

The government has decided to make mandatory the use of Indian Standard Time for all legal, commercial, digital and administrative activities, Food and Consumer Affairs Minister Pralhad Joshi said on Wednesday. This initiative will translate into more secure digital transactions, accurate billing in utilities, reduced cybercrime risks and synchronized timekeeping in transportation and communication. Presently, several systems rely on foreign sources of time. To make Indian Standard Time (IST) mandatory, the government will shortly notify Legal Metrology (Indian Standard Time) Rules, 2025. The draft rules were issued in January 2025 for stakeholders' feedback. On Wednesday, the Department of Consumer Affairs organized a round table conference on Time Dissemination here. Joshi emphasized on the strategic significance of the Time Dissemination Project being implemented by the department in collaboration with CSIR-NPL and ISRO. He said the upcoming rules will mandate synchronization

Elon Musk raises concerns over ISS safety, urges de-orbiting within 2 years

Elon Musk has voiced serious concerns over the long-term safety of the International Space Station (ISS), citing the ageing condition of its components, and called for its de-orbiting within two years despite SpaceX's ongoing involvement."There are potentially serious concerns about the long-term safety of the @Space_Station. Some parts of it are simply getting too old, and that risk grows over time."Even though @SpaceX earns billions of dollars from transporting astronauts & cargo to the ISS, I nonetheless would like to go on record recommending that it be de-orbited within 2 years," Musk posted on X.Meanwhile, the Indian Space Research Organisation (ISRO) is working closely with Axiom Space, NASA, and SpaceX to responsibly address the ISS Zvezda module observation causing the Ax-4 delay, reflecting growing collaboration between India and leading global space agencies, including Musk's companies.V Narayanan, the Secretary DOS/ Chairman ISRO and Chairman Space Commission, said ..

Isro successfully conducts third hot test of semicryogenic engine

The Indian Space Research Organisation on Monday achieved a significant milestone with the successful completion of the third hot test of the Power Head Test Article (PHTA) at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu. The test is part of a crucial series of evaluations to validate the performance of India's upcoming semicryogenic engine, ISRO said. This marks the third in a series of hot tests undertaken by ISRO for the PHTA. According to ISRO, the test, conducted on May 28, was aimed at validating the engine's ignition and start-up sequence while optimising the process for integrated engine performance. During the three-second trial, the engine was ignited successfully and operated up to 60 per cent of its rated power level, exhibiting stable and controlled performance throughout. ISRO began this series of performance evaluations in March 2025, focusing on critical components such as low- and high-pressure turbo-pumps, the pre-burner, start-up system, and various .

Women comprise around 20% of Isro workforce: VN Narayanan

ISRO chairman V Narayanan has said women employees comprise around 20 per cent of the workforce of the premier space research organisation and they are doing an outstanding job. He said the percentage of women employees in ISRO should go up to 40 per cent plus in the future. The ISRO chairman, who was speaking to reporters on the sidelines of a function organised by a private school here on Thursday said, "that in a country like India, having 50 per cent women population, the country cannot progress unless the women contribute in a significant way." Asked about the women workforce in ISRO, Narayanan said, "There are a lot of women employees. The women are doing an outstanding job and they should be encouraged in their contribution. Gradually the number should go up. Right now, maybe there are around 20 per cent women scientists but it should go up to 40 per cent plus." Talking about social reformer Rammohan Roy, he said Roy and other luminaries and polymaths had championed the caus

Isro forms panel to probe PSLV mission failure: Chairman Narayanan

ISRO has formed a committee to investigate the incident in which a PSLV rocket failed to place an Earth observation satellite (EOS-09) into its intended orbit, Chairman V Narayanan said on Sunday. The committee has held several rounds of discussions to identify the cause, he added. Earlier in the day, ISRO failed to place its Earth observation satellite in orbit after the trusted PSLV rocket developed a fault minutes after launch from Sriharikota, about 135 km from here. "Today, we had the 101st mission from Sriharikota. The rocket is a four-stage vehicle. The first stage comprises a 134-tonne solid propulsion system and has six strap-on motors, each holding 12 tonne of propellant. The second stage has a 40-tonne liquid propulsion system, the third stage an 8-tonne solid propulsion system, and the fourth stage again uses liquid propulsion. These four stages must work in tandem to place a satellite into orbit," Narayanan explained. After a 22-hour countdown, the rocket lifted off as

US firm Vast keen to use Indian rockets for rides to planned space station

US-based company Vast, planning to launch the world's first commercial space station next year, has evinced interest in using Indian rockets to transport crew members to its orbital laboratory. Vast CEO Max Hoat met the Indian Space Research Organisation (ISRO) leadership team on the sidelines of the Global Space Exploration Conference here to discuss possible collaborations in the area of space technology. The space-habitation company is in the race to build a space station that will be the successor to the International Space Station, which will be retired by 2031. The California-based company plans to launch Haven-1, a single-module space station, on a SpaceX Falcon 9 rocket in May 2026. "Right now, we are on track with our launch for May 2026," Hoat told PTI in an interview. Vast plans to conduct a series of tests on the space station, before flying astronauts to the orbital laboratory by July next year. The first module of Haven-2, a much larger space station, is expected to
