Cliff, did you post this on Casebook? I couldn't find it here.
Take 2 trips around Earth, from space
By Eleanor Imster in SPACE | November 30, 2018
The European Space Agency (ESA) released this timelapse video this month (November 19, 2018) in celebration of the launch 20 years ago of the International Space Station (ISS). ESA astronaut Alexander Gerst acquired the images for the timelapse in October 2018. At just under 15 minutes, it’s the longest-yet continuous timelapse from space.
The video takes you from Tunisia across Beijing and through Australia in two trips around the world. You can follow the Station’s location on the map at the top right of the screen beside annotations on the photos themselves. Because the map is a two-dimensional representation of Earth’s globe, the ground track of the ISS appears to be wavy.
This timelapse comprises more than 21,000 images of Earth captured by Gerst from the ISS orbiting at its 250-mile (400-km) altitude about our world’s surface. The video is shown 12.5 times faster than actual speed.
At 18,000 miles (28,800 km) per hour, it only takes 90 minutes for the ISS to make a complete circuit of Earth, so the video shows the world passing from day to night and back again twice. The darker regions on the map shows where night is on Earth.
You can see numerous flashes of lightning during night time. That’s lightning from storms and is common on our planet. Also at night, look for stars rising above the horizon through the faint glow of the atmosphere still illuminated by the sun.
