The real origin of Space Harrier

That’s not a bomb crater—it’s aluminum struck by a half-inch plastic fragment traveling at 15,000 mph, simulating a real orbital debris collision. These hypervelocity impacts demonstrate how even small objects can destroy spacecraft in low Earth orbit, where relative speeds exceed 6.7 km/s. That’s why space agencies like NASA and ESA design satellites with specialized shielding like the Whipple shield—a layered defense that vaporizes debris before it hits critical systems. #SpaceDebris #OrbitalVelocity #NASA #ESA #HypervelocityImpact

Moss is a highly underestimated plant that offers significant environmental benefits. Studies show that moss-covered areas can store billions of tons more carbon than bare ground, making moss a powerful tool for carbon capture. Unlike most plants, moss thrives without soil and can grow on walls, roofs, and other urban surfaces, making it ideal for greening cities. In urban areas, moss helps cool temperatures through evaporation and can absorb pollutants like CO₂ and fine dust, improving air quality. It also supports biodiversity and aids in rainwater retention. Despite these advantages, moss is often removed during construction or landscaping due to aesthetic preferences. Embracing moss in city design could play a crucial role in tackling climate change, reducing pollution, and creating healthier living spaces.

This stunning view of Mount Fuji was captured from the International Space Station (ISS), revealing Japan’s iconic volcano piercing through a sea of clouds. Rising 3,776 meters (12,389 feet) above sea level, Mount Fuji is not only Japan’s tallest peak but also a sacred symbol of beauty, endurance, and national pride. Seen from orbit, its nearly symmetrical cone stands out dramatically against the surrounding landscape, showcasing the powerful forces of nature that shaped it. Mount Fuji is an active stratovolcano, with its last eruption occurring in 1707. It continues to attract millions of climbers, photographers, and spiritual seekers each year. This image, taken by astronauts aboard the ISS, highlights how Earth's natural wonders appear from above—and how even the most familiar landmarks take on new significance when seen from space. #MountFuji #EarthFromSpace #ISS #Astronomy #Volcano #Japan #Nature

Astronaut Charlie Duke glances back at the Lunar Module Casper—the very craft that brought him to the Moon during the Apollo 16 mission. This image reflects the profound sense of wonder that space exploration inspires and the lasting bond astronauts have with the vehicles that carried them on their extraordinary voyages. #Apollo16 #MoonLanding #SpaceExploration #Astronomy #Moon
