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...
Quantum-Based Atomic Clock: A Breakthrough in Ultra-Precise Timekeeping Content Introduction : Scientists in the United Kingdom have developed a quantum-based atomic clock , representing a major leap in timekeeping accuracy. What is an Atomic Clock? A clock that uses the resonance frequencies of atoms (usually cesium or rubidium ) to measure time with remarkable precision. These clocks are the most accurate timekeeping devices in the world. Quantum-Based Innovation : The new quantum-based atomic clock can lose less than one second over billions of years . It leverages quantum mechanics for improved frequency control and stability. Benefits : Global Navigation Satellite Systems (GNSS) : Enhanced precision in GNSS improves the accuracy of GPS and other positioning systems. Advanced Weapon Systems : Enhances the precision of guided missiles and defense systems by providing ultra-stable time references. Scientific Research : Enables highly accurate time measurements critical for astrophy...
