Painted markings on the service structure of Site 1 at the Baikonur Cosmodrome seen on Friday, July 19, 2019, show the milestones accomplised by launches from the historic pad. The markings commemorate the first launch from the pad on May 15, 1957, the launch of Sputnik 1 on October 4, 1957, the launch of the first human to orbit Earth, Yuri Gagarin, on April 12, 1961, and the fact that the pad has been the site of over 500 launches of various rockets since its construction. Expedition 60 Soyuz Commander Alexander Skvortsov of Roscosmos, flight engineer Andrew Morgan of NASA, and flight engineer Luca Parmitano of ESA (European Space Agency) launched from the historic pad to begin their mission to the International Space Station at 12:28 p.m. Eastern time (9:28 p.m. Baikonur time) on July 20th.
