NASA INDEFINITELY DELAYS RETURN OF STARLINER TO REVIEW PROPULSION DATA

Summary from the TLDR newsletter

NASA has adjusted the date of the Starliner spacecraft's return to Earth to an unspecified time in July. The spacecraft was originally due to undock and return to Earth on June 14, but return opportunities have been waved off as more time is needed to review the data from the vehicle's problematic flight to the International Space Station. There were five separate leaks in the helium system that pressurizes Starliner's propulsion system and five of the vehicle's 28 reaction-control system thrusters failed as Starliner approached the station. NASA has not specified why it is not yet comfortable with releasing Starliner to fly back to Earth.
