Ralph Mirebs, an urban explorer and photographer in Russia, has revealed extraordinary photos of Soviet space shuttle prototypes gathering dust in an abandoned hangar. The abandoned hangar is located at the Baikonur Cosmodrome in Kazakhstan, which is still in operation today (with the close of NASA’s shuttle program, Russian Soyuz shuttles are the only way for astronauts to reach the International Space Station). The Buran prototype shuttles found by Mirebs, however, are from an earlier era – they are the last remnants of a space program that began in 1974 and was finally shuttered in 1993.

A shepherd rides a donkey as he leads sheep during winter in Van, Turkiye on February 19, 2022. Despite the terrible winter weather and the hard geology of the region, breeders in Van's Gurpnar district, where livestock is the most important source of revenue, do not disregard the care of their animals. Livestock farmers in the Cepkenli and Topcudegirmeni neighborhoods have the similar difficulties as those in rural areas, where the snow depth reaches one meter.
