NASA Astronauts Prepare for Key Spacewalk to Study Microorganisms and Conduct Repairs

Tracy C. Dyson and Matthew Dominick will venture outside the ISS for a six-and-a-half-hour mission to collect samples and remove faulty equipment.

The spacewalk is scheduled to start at 8 a.m. EDT on Thursday, June 13, with live coverage beginning at 6:30 a.m. EDT.
Dyson and Dominick will collect microorganism samples from the ISS exterior to study survival in space.
They will also remove a faulty radio frequency group from a communications antenna on the station's starboard truss.
This will be Dyson's fourth spacewalk and Dominick's first.
NASA's Starliner crew will stay at the ISS longer due to ongoing assessments of their spacecraft.
