Boeing’s Starliner spacecraft’s valves may have frozen because they couldn’t handle Florida’s humidity, according to a report by United Press International. UPI quotes NASA and Boeing spokespeople as saying the famous Florida stickiness may have caused corrosion in the valves that kept them from functioning prior to a an uncrewed test launch of the capsule in August. The fuel oxidizer that flows through some of those valves apparently reacted to the humidity and the resulting corrosion locked up the valves.
