Boeing's Starliner launch to International Space Station scrubbed due to glitch

And by the sounds of things, they might not launch this year.

The problem is so complicated, they don't know what is causing it. They had some indications that some valves were not in their proper pre-launch positions, but now, apparently they don't know if it was a sensor issue, or an actual valve issue, so they are having to take more time to figure that out, and the schedule for the rest of the year is looking complicated, as there is likely to be a crowd at the ISS after SpaceX launches their next supply run. And then Lucy, and the time needed to prep the rocket on the pad before it launches. It might not launch before late October, November, possibly into November.

Ouch...
