NASA’s Curiosity Rover May Have Uncovered the Mystery of Mars’ Missing Carbonates

Space & Environment, Tech /

New analyses from NASA’s Curiosity rover offer important clues about the fate of Mars’ ancient atmosphere and the processes that shaped the planet over time. A Long-Standing Carbonate Mystery For years, scientists have believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on its surface. Theoretically, this combination should have led […]

Over 6,600 Tons of Space Junk Are Floating Around in Earth’s Orbit

Space & Environment /

Decades of launching satellites into space have created a growing orbital pollution crisis. According to the Annual Space Environment Report from the European Space Agency (ESA), more than 6,600 tons of space debris are currently drifting in Low Earth Orbit (LEO), between 100 and 1,200 miles (160–2,000 km) above Earth’s surface. That’s an increase from
