ISS astronauts prepare for Russian lab arrival - Hindu Business Line

Moscow, July 10:   Two astronauts prepared the International Space Station for the installation of a new Russian laboratory module during a six-hour spacewalk on Tuesday. Christopher Cassidy of the United States and his Italian colleague Luca Parmitano started their spacewalk at 8:02 am EDT (1202 GMT) and ended at 1809 GMT, NASA said on its website. Cassidy replaced a failed space-to-ground transmitter and Parmitano retrieved two experiments. The two attached grapple bars to thermal radiators to make them easier to remove should they fail. Parmitano removed a failed camera assembly used for monitoring visiting spacecraft. The camera will be repaired on Earth and returned as a spare on a later mission. Cassidy routed power cables to support the installation of Nauka, the new Russian multi-purpose laboratory module, which Russian cosmonauts will bring to the station later this year. It was Cassidy's fifth spacewalk, but the first for Parmitano, who started his first ISS mission on May 29. The next spacewalk is scheduled to take place on July 16.
