Another delay for Boeing Starliner heading to space, indicates the aerospace company’s worries are continuing. Next chance for launch will be May 21st.

WASHINGTON (Reuters) -Boeing’s first Starliner mission carrying astronauts into space has been delayed again – until at least May 21 – over an issue with the spacecraft’s propulsion system, the company said on Tuesday. Starliner’s mission carrying two NASA astronauts had been scheduled for liftoff from Florida last week until a technical issue with its Atlas 5 rocket prompted a delay to Friday, May 17, the latest postponement for a program years behind schedule and more than $1.5 billion over budget. A new technical issue, now concerning Starliner itself, has prompted another postponement to at least next Tuesday, Boeing said in a statement.
