Astronauts stranded on ISS until August
Their return flight has been repeatedly delayed due to safety concerns.
NASA engineers are working to ensure the safety of the Starliner before allowing the astronauts to return.
The crew rotation on the ISS is scheduled for mid-August, serving as a deadline for the plans.
While the astronauts express confidence in the spacecraft's ability to bring them home safely, NASA's commercial crew chief acknowledges challenges with thruster tests.
Alternative transportation options, such as SpaceX's Crew Dragon or a Russian Soyuz capsule, are available if necessary.
