 NASA managers wanted to complete a pair of spacewalks on the space station before trying to bring the Starliner crew home. Boeing engineers would use the time to try to understand ammonia leaks and thruster failures that developed during Starliner's test flight. Instead, a coolant leak in a spacesuit canceled a spacewalk, throwing off that timeline. Astronauts Butch Wilmore and Sonny Williams remain safe on the ISS, awaiting their return. I'm Rory O'Neill.
