NASA astronaut Steve Bowen and United Arab Emirates astronaut Sultan Alneyadi are conducting a spacewalk on Friday, April 28, 2023, to continue upgrading the International Space Station's power generation system. The spacewalk is scheduled to begin at about 9:15 a.m. EDT (1315 UTC), and last about 6 hours and 30 minutes; it is part of a series to augment the station's power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four of the new iROSAs have been installed so far.
