CAIRO: In his 179th day in space, American Astronaut Scott Kelly captured a breath- taking photo of Egypt’s Nile and tweeted it on Sept. 22.
Once tweeted, the Nile photo captured the attention of many, attracting many comments praising its beauty; the photo garnered 6,727 favorites and 4,825 retweets 15 hours after posting.
The National Center for Earth and Space Science Education (NCESSE) website said on Tuesday that the photo was captured from a distance of 300 miles, at the International Space Station speed of 17,154 miles/hour, which means that Kelly passed by this area in one minute.
This is not the first time for Kelly to tweet a photo for the Egyptian Nile; in his 121st day, he tweeted “Day 121. The Nile at night is like a jewel.”
Also, on Sept. 4, in his 161st day, he tweeted a photo for Egypt’s Red Sea, describing it as “very blue.”
And on May 29, Kelly posted a photo of the Pyramids of Giza, congratulating the first person to identify them on the map photo.
Astronaut Kelly started his one-year space mission March 27, with cosmonaut Mikhail Kornienko; the trip was launched from Baikonur in Kazakhstan in a Soyuz vehicle, according to the Daily Mail.
The 12-month space trip is called “NASA Twin Study,” in which the Kelly twins take part, Scott Kelly went to space, while his identical twin Mark Kelly stayed on Earth allowing for a study on bodies of genetically identical persons.
The newspaper added that this experiment is the first of its kind that aims to test the ability of human body to cope with long-term space travel.
According the Daily Mail, both Kellys will be subjected to 10 experiments in areas of human physiology, behavioral health and microbiology.
