NASA Alerts: Two Asteroids Near Earth Today

Brief by Shorts91 Newsdesk / 05:42pm on 17 Apr 2024,Wednesday Science

NASA issues alert on two asteroids passing close to Earth on April 17. 2024 GM1, sized like an airplane, approaches within 1.3 million kilometers at 37,287 km/h. 2024 GF5, bus-sized, nears at 3.7 million kilometers, traveling at 26,485 km/h. Despite their speed, NASA assures they're safe. The agency closely monitors near-Earth objects (NEOs) and sets safety thresholds. Only larger objects within 7.5 million kilometers are considered potential hazards. Ground and space-based telescopes track NEOs, providing valuable data. Though not visible to the naked eye, the event highlights space's vastness and NASA's vigilance in protecting Earth.

ISRO Achieves Breakthrough with Lightweight Carbon-Carbon Rocket Engine Nozzle

Brief by Shorts91 Newsdesk / 12:51pm on 16 Apr 2024,Tuesday Science

The Indian Space Research Organisation (Isro) has successfully developed a lightweight Carbon-Carbon (C-C) nozzle for rocket engines, marking a significant breakthrough in rocket engine technology. This innovation promises to enhance vital parameters like thrust levels, specific impulse, and thrust-to-weight ratios, boosting the payload capacity of launch vehicles. By replacing metallic nozzles with lightweight C-C counterparts, a mass reduction of approximately 67% can be achieved, potentially increasing the payload capability of the PSLV by 15kg. After successful hot tests, this collaborative effort involving VSSC, LPSC, and IPRC has validated the nozzle's capabilities, paving the way for advanced rocket propulsion systems.
