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 astrophysics, quantum computing, and space exploration.
- Telecommunications: Improves the synchronization of networks for faster data transfer and lower latency.
Conclusion:
The quantum-based atomic clock marks a significant advancement in timekeeping, with potential applications across various industries, including defense, space, and telecommunications.
