On August 9th, two Russian cosmonauts, Ivan Vagner and Sergei Ryzhikov, will be embarking on a spacewalk in order to conduct science experiments and repair a telescope. This spacewalk will also replace some of the cables and antennas for a further communication link between the International Space Station and Earth. This spacewalk is expected to last around 6 1/2 hours and will be live-streamed for anyone interested in watching.
