US astronaut Tim Kopra has shared a photo showing a night-time view of Singapore – as seen from the International Space Station (ISS), 420km above the Earth.
The photo, taken with a digital camera, was tweeted by Mr Kopra on Saturday (Mar 19). It has since been retweeted more than 1,000 times and received 2,500 likes.
The 52-year-old, who assumed command of the ISS last December, has also shared night-time photos of several other cities, including Beijing, New York and New Delhi.
The ISS orbits roughly 420km above the surface of the Earth every 90 minutes at a speed of 28,000km/h.
“Clearly, Singapore was important to include as the station’s orbital path and free crew time on station for photography allows,” said Mr Dwayne Lawrence, Executive Director of Friends of NASA, which shared the photo on its Facebook page.
“It appears the station was moving in its counter-clockwise low-Earth orbit over the Indian Ocean approaching from the West when the photo was taken,” he added.
