TWO Falcon 9 launches in one day The pace SpaceX is launching is just Insane… For the rest of the space industry, it takes months or years to pull off one launch But in the last 24 hours, SpaceX completed TWO flawless missions: • 119 payloads delivered to orbit • 29 more Starlink satellites launched That’s 148 satellites in ONE DAY and this is quite routine for SpaceX SpaceX is operating on a completely different level











Happy Birthday to Galileo Galilei.✍️ Born on February 15, 1564, Galileo was a pioneering scientist whose observations transformed humanity’s understanding of the universe. Through his telescopic discoveries - including the moons of Jupiter and the phases of Venus - he provided powerful evidence that challenged long-held beliefs and supported the motion of the Earth. Widely regarded as the Father of modern astronomy, his dedication to observation, evidence, and scientific inquiry laid the foundation for modern science.


Everyone says “Linux is secure and viruses don’t attack it easily” But why is that actually true? Very few people know the real reasons: 1. Linux user permissions are strict by design In Linux, normal users don’t have admin (root) access by default. Malware can’t install system-level files unless it explicitly gets root permission - which usually requires your password. No silent installs. 2. Software comes from trusted repositories Unlike Windows/macOS where people download random .exe files, Linux users install apps from official, cryptographically signed repositories. This massively reduces the chance of installing infected software. 3. Open-source = constant inspection Linux is open-source. Thousands of developers worldwide continuously inspect, audit, and improve the code. If a vulnerability appears, it’s often found and patched quickly - sometimes within hours. 4. No single point of failure Linux isn’t one OS - it’s hundreds of distributions (Ubuntu, Fedora, Arch, etc.). A virus written for one distro often won’t work on another. Malware authors hate fragmentation. 5. Kernel-level security features Linux uses advanced protections like: • SELinux / AppArmor (mandatory access control) • Address Space Layout Randomization (ASLR) • Secure memory handling Even if malware runs, its damage is heavily restricted. 6. Fewer users = lower incentive Linux dominates servers, not desktops. Hackers usually target platforms with maximum users for maximum profit. Desktop Linux simply isn’t the most lucrative target. 7. Fast updates, no forced delays Linux updates are lightweight, frequent, and optional - but encouraged. Vulnerabilities stay open for less time. 8. Command-line transparency Most system-level actions are visible. Nothing hides behind flashy installers. Suspicious behavior is easier to detect for experienced users. Conclusion: Linux isn’t “virus-proof” - nothing is. But its architecture, permissions model, open-source nature, and security-first design make it far harder to attack than most operating systems.



By studying samples analyzed by the Curiosity rover, scientists have taken another step toward understanding whether life could have ever existed on Mars. A new study suggests that non-biological sources cannot fully account for the abundance of organic compounds found in a sample collected by the rover.
