Boeing's Starliner crewed test flight postponed due to technical glitch, competing with SpaceX for NASA business.
The long-awaited first crewed test flight of Boeing's Starliner spacecraft was called off for at least 24 hours over a technical glitch with the Atlas V rocket that was being readied to launch the new astronaut capsule to orbit on Monday night.
The CST-100 Starliner's inaugural voyage carrying astronauts to the International Space Station (ISS) has been highly anticipated and much-delayed as Boeing scrambles to compete with Elon Musk's SpaceX for a greater share of lucrative NASA business.

It comes two years after the gumdrop-shaped capsule completed its first test flight to the orbital laboratory without humans aboard. The Starliner's first uncrewed flight to the ISS in 2019 ended in failure.
Its latest flight was scrubbed with less than two hours left in the countdown as the capsule stood poised for blastoff from NASA's Kennedy Space Center in Florida atop an Atlas V rocket furnished by United Launch Alliance, a Boeing-Lockheed Martin joint venture.
The postponement, attributed to an issue with a valve in the Atlas rocket's second stage, was announced during a live NASA webcast.
It was not immediately clear how long the issue would take to address, but the next available launch windows for the mission are Tuesday, Thursday and Friday nights.
