[b]First Launch Attempt for Starliner Crew Flight Test Scrubbed[/b] [i]Flight teams standing down due to valve issue on upper stage of launch vehicle.[/i] Boeing's Starliner spacecraft atop the United Launch Alliance Atlas V rocket, on the launch pad of Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on Monday, May 6. (NASA photo) United Launch Alliance (ULA), with concurrence from Boeing and NASA, scrubbed the launch a little more than two hours ahead of the originally scheduled liftoff time of the CST-100 Starliner Crew Flight Test on Monday, May 6. NASA astronauts Butch Wilmore and Suni Williams safely exited Starliner and returned to crew quarters, following the decision to stand down from launch for the day. The scrub was recommended after launch control teams detected anomalous behavior by the pressure regulation valve in the liquid oxygen tank of the Centaur upper stage of the ULA Atlas V launch vehicle. Engineers are analyzing the data to fully understand the issue and determine any corrective actions. Mission managers will convene to decide next steps and potential timing for another launch attempt. [b]Update[/b]: Boeing, NASA and United Launch Alliance have made the decision to allow engineering teams to spend Tuesday, May 7, evaluating the data and the next launch opportunity will be no earlier than Friday, May 10.
