The International Space Station streaks across the face of the Moon! The ISS travels at 28,000 km/h (17,500 mph) — completing an orbit around Earth roughly every 90 minutes. It only takes about half a second for it to cross the Moon from our perspective! Astronauts aboard experience 16 sunrises and sunsets per day. Spotting the ISS requires perfect timing — these lunar transits are often visible from just a few kilometers-wide path on Earth. #NASA #spaceexploration #SpaceX | Astro Clips

Sebuah roket pengangkut Soyuz-2.1a diluncurkan dari Baikonur Cosmodrome di Kazakhstan pada Kamis (27/11), mengirim wahana antariksa Soyuz MS-28 dengan dua kosmonaut Rusia dan satu astronaut Amerika Serikat (AS) ke orbit dekat Bumi. Wahana antariksa tersebut lepas landas pada pukul 12.28 waktu Moskow (pukul 16.28 WIB). Wahana itu diperkirakan akan menyelesaikan dua putaran mengelilingi Bumi sebelum merapat ke Stasiun Luar Angkasa Internasional (International Space Station/ISS) dalam waktu sekitar

The ISS follows a stable orbit around the Earth, while the Earth rotates beneath it. The International Space Station (ISS) orbits the Earth at a consistent altitude and speed, moving along a predetermined path. As the Earth rotates on its axis, different parts of the planet come into view below the ISS, giving the appearance that the station is passing over different locations. However, it’s the Earth that’s rotating within this fixed orbital path, not the ISS moving over a stationary Earth. Vid
