The
spacewalk or EVA (Extra-vehicular activity) to replace a defect
component outside the International Space Station is about to begin.
NASA provides live coverage at: http://www.ustream.tv/nasahdtv/theater
NASA astronauts Rick Mastracchio and Steve Swanson are scheduled to venture outside the space station to replace a backup multiplexer-demultiplexer (MDM) that failed during routine testing April 11. The box is one of the station's two external MDMs that provide commands to some of the space station's systems, including the external cooling system, solar alpha rotary joints and mobile transporter rail car. The EVA is scheduled to take about 2.5 hours.
The main spacewalk is over. A recording of the coverage is available here: http://www.ustream.tv/recorded/46572062 starting at 00:53:00.
