On June 9, NASA astronauts
Steve Bowen and Woody Hoburg will exit the station's Quest
airlock to install an upgraded IROSA (International Space Station
Roll-Out Solar Array) on the 1A power channel on the starboard

astronauts will install an IROSA on the 1B power channel on the starboard truss.
Assignments for U.S. EVA 88 will be determined at a later date.
The spacewalks will see the fifth and sixth IROSAs mounted
to the existing station solar arrays. The new arrays are 60 feet
long by 20 feet wide (18.2 meters by 6 meters) and will shade a
little more than half of the original arrays, which are 112 feet
long by 39 feet wide. The seventh and eighth IROSAs will be
installed on future spacewalks. Each new IROSA will produce more
than 20 kilowatts of electricity, and once all eight are installed,
will enable a 30% increase in power production over the station's
