NASA flight director discusses curtailed spacewalk

January 16, 2016 Spaceflight Now

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.

Flight controllers ordered two astronauts to terminate a spacewalk outside the International Space Station Friday after one of them reported a small amount of water leaking into his space helmet.

Astronauts to repair station electrical circuit on Friday spacewalk

January 14, 2016 William Harwood

Two space station astronauts are gearing up for a planned six-and-a-half-hour spacewalk Friday to replace a presumably shorted out solar array voltage regulator that knocked one of the lab’s eight power channels out of action late last year.

Successful spacewalk frees up robot arm transporter

December 21, 2015 William Harwood

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.

Unscheduled spacewalk on tap Monday

December 20, 2015 William Harwood

An unexpected, quickly-planned spacewalk is on tap Monday to troubleshoot a problem preventing the International Space Station’s robot arm transporter from reaching a worksite where it can be locked down, a requirement before a Russian Progress cargo ship can dock later in the week.

Spacewalk snapshots show recent station EVAs

Clad in white spacesuits, astronauts Scott Kelly and Kjell Lindgren recently floated outside the International Space Station on a pair of spacewalks, and the duo carried cameras with them to document the excursions.

Spacewalkers reconfigure station cooling system

November 6, 2015 William Harwood

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.

Kelly, Lindgren set for second spacewalk

November 5, 2015 William Harwood

Space station commander Scott Kelly and flight engineer Kjell Lindgren are gearing up for their second spacewalk in nine days Friday, a planned six-and-a-half-hour excursion to reconfigure the ammonia cooling system used by one of the lab’s sets of solar arrays.

Station astronauts complete tedious spacewalk

October 28, 2015 William Harwood

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.

Station astronauts gearing up for spacewalk Wednesday
