NASA’s lead spacewalk flight director Royce Renfrew talks with public affairs office Rob Navias about the curtailed spacewalk by astronauts Tim Kopra and Tim Peake on January 15, 2016. Although the spacewalk’s major objective to replace a failed voltage regulator was a success, the spacewalk was cut short when a small water bubble had formed inside Kopra’s helmet.
Space station commander Scott Kelly and newly-arrived flight engineer Tim Kopra ventured outside the lab complex Monday and freed up a stalled robot arm-carrying transporter so it could be moved to a nearby anchor point and locked down, clearing the way for a Russian Progress supply ship to dock Wednesday.
Space station commander Scott Kelly and Kjell Lindgren carried out a busy but mostly trouble-free spacewalk Friday, routing ammonia coolant back to the prime radiator used by one of the lab’s solar arrays and bypassing a secondary radiator that was activated three years ago to help pinpoint a coolant leak.
Space station commander Scott Kelly and Kjell Lindgren carried out a tedious seven-hour 16-minute spacewalk Wednesday, installing cables needed for a new docking mechanism, mounting insulation panels on a physics experiment to improve cooling and lubricating the latching mechanism of the station’s robot arm.
