A no brainer fact - Earth is 70% water. One would think capturing a continuous 9,000-km landmass would be a bit tricky. But Nasa has achieved the landmark.
A Nasa satellite has captured a 9,000-km swath of nearly unbroken land from Russia to South Africa, thus photographing arguably the world’s largest continuous panorama, reports CNET.
Capturing the strip of continuous landmass — disrupted only by a bit of the Red Sea — was a challenge as Earth is made up of over 70% water.

The Landsat Data Continuity Mission (LDCM) satellite clicked the landmass on April 13. Flying at an altitude of 705km above earth at a speed of 27,000km per hour, the distance was covered in 20 minutes.
The website says, “NASA slightly increased the speed when creating a video of the images, so, in all, it only takes about 15 minutes (imagine if you could do that in an aeroplane). The result is a view of what it would be like to be watching the Earth fly by below if you were a passenger on the LDCM.”
The satellite took photos with its operational land imager. The 56 images were stitched together in a seamless 185km wide, 9,000km panorama called “The Long Swath”.
