Israel Launches New Military Surveillance Satellite into Space

  • Israel launched its latest spy satellite into space from an undisclosed site.
  • The Ofek 19 satellite was built by state-run Israel Aerospace Industries (ISRAI.UL).
  • Ofek 19 is a highly advanced SAR (synthetic aperture radar) observation satellite with enhanced capabilities. Upon entering Earth's orbit, the satellite will undergo a series of designated tests to assess its integrity and performance.

  • India took a major stride in its semiconductor journey with the unveiling of Vikram�'3201, the country's first "Made�'in�'Bharat" 32�'bit microprocessor. Presented by Union Minister Ashwini Vaishnaw to Prime Minister Narendra Modi at Semicon India 2025 in New Delhi, this milestone underscores India's growing technological autonomy and ambition to become a global hub for chip manufacturing.
  • India launched the India Semiconductor Mission in 2021 to reduce dependence on foreign microprocessors. In just three and a half years, the country transitioned from being a major consumer to a producer of advanced chips.

Tiny Computer to Aid India's Hunt for Cosmic Dawn Signals

  • A compact single-board computer (SBC), no larger than a credit card, is poised to play a pivotal role in unlocking secrets of the Cosmic Dawn—the epoch when the first stars and galaxies began illuminating the universe. Developed by the Raman Research Institute (RRI), Bengaluru, this breakthrough is part of India's proposed PRATUSH mission to the Moon, aiming to detect one of the faintest radio signals ever observed.
  • PRATUSH (Probing ReionizATion of the Universe using Signal from Hydrogen) can help detect a faint radio signal emitted from hydrogen atoms (21-cm signal), which carries imprints of several events of the Cosmic Dawn. Capturing this signal is like hearing a whisper in a stadium full of noise because it is buried under interference, millions of times stronger than the signal itself.
