In a landmark moment for India's space ambitions, Indian astronaut Shubhanshu Shukla has blasted off to the International Space Station (ISS) as part of the Axiom-4 mission , marking the country's return to human spaceflight after a 41-year hiatus . This historic launch from NASA’s Kennedy Space Center in Florida has not only reignited national pride but also officially kickstarted India’s human spaceflight programme . The mission, operated by Axiom Space , includes a four-member international crew that will spend 14 days in orbit , conducting scientific research, outreach programs, and various commercial activities. This momentous occasion places India among a select group of nations capable of sending humans into space and reflects the growing prowess of the Indian space sector . A New Chapter: Shubhanshu Shukla and India’s Astronautical Comeback The last Indian to go to space was Rakesh Sharma in 1984, aboard the Soviet spacecraft Soyuz T-11. Now, in 2025, Shubhanshu...
Introduction In the ever-evolving world of science and technology, the quest for precision and accuracy never ceases. One of the most groundbreaking advancements recently making waves in the scientific community is the development of a nuclear clock that is so precise it could redefine how we measure time itself. This revolutionary technology has the potential to transform industries reliant on ultra-precise timing, from global positioning systems (GPS) to quantum computing and even fundamental physics research. What is a Nuclear Clock? A nuclear clock operates on the principle of nuclear transitions rather than electronic transitions, as seen in atomic clocks. While atomic clocks, such as cesium or rubidium-based devices, are already extremely accurate, nuclear clocks take precision to a whole new level. The heart of a nuclear clock typically involves a specific isotope that undergoes energy transitions within its nucleus rather than its electron cloud. These nuclear transitions are f...
