Two NASA astronauts, commander of Expedition 42 Barry Wilmore and flight engineer Terry Virts, are conducting a spacewalk to prepare the International Space Station (ISS) for the arrival of commercial spacecraft.
Samantha Cristoforetti, a European Space Agency astronaut from Italy, assists Wilmore and Virts from inside the station as they lay cables to bring power to docking adapters.
