The Indo-Pak orange line four years later

leave a comment »

Almost exactly four years ago, in September 2011, the border between India and Pakistan was photographed by an astronaut on the International Space Station. It showed the border as a long orange line, one of the few international borders that can be seen from low earth orbit.

On 23 September 2015 the space agency NASA released a new picture. The line is as long and orange as it was, perhaps more fortified now. The cities visible on both sides of the very well lit frontier are more populous, and certainly emit more light in 2015 than they did in 2011.

I have added names to the clusters of bright lights seen in the new photograph. In western Rajasthan, Jodhpur, Barmer, Bikaner and Jaisalmer are all visible. In southern Pakistan, Karachi and Hyderabad are easily made out. The media has used the new photographs too, as you can see here, here, here and here.

A high resolution image is available here from Nasa’s Earth Observatory website. Another night image shows the border zone looking south-east from the Himalaya. An older daytime view shows the vegetated bends of the Indus Valley winding through the otherwise desert landscape.
