Overview

  • Starliner, on its first crewed mission, has been at the ISS since June 6, far beyond its planned nine-day stay.
  • Engineers are conducting extensive tests to understand and resolve thruster and helium leak problems.
  • The spacecraft can return in an emergency, but NASA aims to ensure all issues are addressed before undocking.
  • Astronauts Wilmore and Williams are assisting with ISS maintenance and science experiments during the delay.
  • The latest possible return date is mid-August, contingent on resolving technical issues and upcoming crew rotations.
