The American Boeing company is about to run another demonstration mission of its new astronaut capsule.
The CST-100 Starliner is set to launch from Florida to showcase how it can ferry crews to and from the International Space Station (ISS). It will be the second test flight, and conducted with no people aboard. A similar demonstration run in 2019, encountered software problems that very nearly resulted in the loss of the capsule. The Starliner will ride to orbit on an Atlas-5 rocket from the Cape Canaveral Space Force Station in Florida. Lift-off is timed for 13:20 local time (17:20 GMT; 18:20 BST).
