This video offers A timelapse of Earth in 4K resolution, as imaged by the geostationary Elektro-L weather satellite, from May 15th to May 19th, 2011.
James Tyrwhitt-Drake who processed the image data and uploaded the video to YouTube said:
“Elektro-L is located ~40,000 km above the Indian ocean, and it orbits at a speed that causes it to remain over the same spot as the Earth rotates. The satellite creates a 121 megapixel image (11136×11136 pixels) every 30 minutes with visible and infrared light wavelengths. The images were edited to adjust levels and change the infrared channel from orange to green to show vegetation more naturally. The images were resized by 50%, misalignments between frames were manually corrected, and image artifacts that occurred when the camera was facing towards the sun were partially corrected. The images were interpolated by a factor of 20 to create a smooth animation. The animation was rendered in the Youtube 4K UHD resolution of 3840×2160. An original animation file with a resolution of (5568×5568) is available on request.
To answer frequently asked questions; why are city lights, the Sun, and other stars not visible? City lights are not visible because they are thousands of times less bright than the reflection of sunlight off the Earth. If the camera was sensitive enough to detect city lights, the Earth would be overexposed. The Sun is not visible due to mechanisms used to protect the camera CCD from direct exposure to sunlight. A circular mask on the CCD ensures that only the Earth is visible. This mask can be seen as pixelation on Earth’s horizon. The mask also excludes stars from view, although they would not be bright enough to be visible to this camera.”
Perhaps you’re familiar with this quote from Apollo 14 astronaut Edgar Mitchell, in which he describes the effects of his view of Earth from space:
“You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, “Look at that, you son of a bitch.”
That “instant global consciousness” is a hallmark symptom for what author and philosopher Frank White first called “The OverView Effect”, in which many astronauts returning from space report to have experienced upon returning home. Thanks to videos like these, we can definitely get an idea of how they were feeling while looking at our beautiful blue space marble.
