WWW.UNIVERSETODAY.COMCould Sweating Spacecraft Make Re-Entry Easier?When ISS astronauts return home, they have a hot ride back to Earth's surface. It's been that way since the beginning of human spaceflight to orbital space and beyond. The incoming vehicle uses friction with Earth's atmosphere to slow down to a safe landing speed. The "hot ride" part comes because that friction builds up high temperatures on the spacecraft's "skin". Without protection, the searing heat of atmospheric re-entry could destroy it. This same heating happens to incoming meteoroids as they whip through Earth's atmosphere.0 التعليقات 0 المشاركات 4 مشاهدة

WWW.UNIVERSETODAY.COMA Collaboration Between China and the West Could Find Dozens of Earth-Like WorldsIf astronomy has a Holy Grail, it's another habitable world. To find one, NASA is working with partners to develop the Habitable Worlds Observatory (HWO). The HWO would be the first telescope built to detect Earth-like planets around Sun-like stars. China is building the Closeby Habitable Exoplanet Survey (CHES), and new research shows that by working together, HWO and CHES would amplify their results.0 التعليقات 0 المشاركات 6 مشاهدة

WWW.UNIVERSETODAY.COMMars Has Many Features that Match EarthResearchers have identified several features on Mars that look surprisingly similar to conditions on Earth. One notable feature is giant wave-like landforms called solifluction lobes, which are in cold, mountainous regions of Earth, like the Arctic or Rocky Mountains. These are slow-moving patterns similar to fluids running downhill, but on Mars, they're 2.6 times larger because of its lower gravity. They can grow much taller before collapsing on Mars.0 التعليقات 0 المشاركات 5 مشاهدة
