Very nice! How do you take a 152-second exposure without overexposing everything else?
ISO 100 at f14. It was 6:36am.

Superb shots! For the 152 second exposure, I presume you used a neutral density filter?
No filters.

Wow! Great shots! Thanks for sharing.... I hope to make it down there to try shots like that. Thanks for sharing!

From a friend of mine who works at Boeing: It was a software problem. The Mission Elapsed Time (MET) was off by enough that the flight software thought the orbital insertion burn had already happened so did not fire the engine. At the same time it was keeping the spacecraft in high precision 'station keeping mode' during the non-existant burn, which uses RCS jets (these are the small jets that control the spacecraft attitude).
This was happening when Starliner was not in communications with flight control due to its position. By they time Starliner regained communications, there was not enough RCS propellant left to safely dock with ISS.
If there had been crew on board, they would have commanded the RCS jets to stop firing and would have plenty of fuel left for docking.
BTW, the shots are fantastic!

We watched the launch from Port Canaveral, about 10-12 miles from the launch pad (#40). Your shots are better than mine! A typical stage 1 lifts the craft to about 40 miles and around 5000 mph I believe. Greg.
