Boeing has scrubbed Tuesday’s planned launch of their Starliner spacecraft on its second uncrewed Orbital Test Flight, called OFT-2, aboard United Launch Alliance’s Atlas V rocket. The issue at hand, according to Boeing, related to incorrect valve position indications in the propulsion system. The issues were first detected during checkouts after thunderstorms storms over launch site on Monday.
Later on Tuesday, Boeing confirmed that teams had cycled the Service Module propulsion system valves and had ruled out a number of potential causes, including software. Wednesday’s potential launch attempt will not proceed. No launch date has been set at this time.
