During an EVA (Extravehicular Activity)/spacewalk from the International Space Station (ISS) which began at 1402 GMT on 18 August 2014, Russian cosmonauts Alexander Skvortsov and Oleg Artemyev, released the Peruvian cubesat Chasqui-1 which had been earlier transported to the ISS on the Progress M-022M cargo craft launched to the station in February.
Built by the Universidad Nacional Ingenieria, Peru, the 1kg cubesat craft is equipped with a visible and infrared imaging system and a simple attitude control system. The five hour 10 minute spacewalk continued with other tasks including the installation of the astrobiology experiment, Expose R, and the collection of science samples. The spacewalk ended when the Pirs airlock hatch was closed at 1912 GMT.
