NASA’s Chris Cassidy and Italian astronaut Luca Parmitano of the European Space Agency were scheduled to work for more than six hours outside the ISS to ready the station for the Russian lab and to conduct a range of maintenance tasks, including replacing defunct communications and video equipment, as well as collecting the results of space experiments, The Associated Press reported.
The prep work for the Russian lab, which is dubbed "Nauka,” or "Science,” will include routing power cables to support the module, Space.com said. Nauka will be used as a research facility and as a docking port, as well as for staging spacewalks for Russian cosmonauts, the website cited NASA officials as saying.
Tuesday’s spacewalk, the first ever for an Italian astronaut, is being broadcast live by NASA.
