> The testing leads the teams to believe that the thrusters are prone to overheating during docking. Higher temperatures may have caused propellant to vaporize, interrupting the mixing of oxidizer and fuel required for the thrusters to properly work, which then reduced the thruster pressure and resulted in the lower readings. But surely they have tested the trusters in a vacuum chamber for the durations they planed to burn them (plus a safety margin). Would be cool to know if such testing didn't happen. Or if it happened but missed the issue for some reason. Perhaps the problem only happens in the integrated configuration, not when they were testing trusters individually? Or perhaps something with sun illumination?
