CST-100 Starliner Pad Abort Test
Surprised nobody has talked about the test on Monday:
https://www.youtube.com/watch?v=acOFK3Bsj58 https://www.youtube.com/watch?v=eiOhR-PhvUw The test went amazingly well! As rocketeers, we can appreciate how hard it was to make a very unstable configuration fly so well - controlled only by alternating thruster firings, not gimbals or control surfaces. As for the failed parachute, Boeing determined the pilot chute broke free from the main- you can see the three pilots pull out, and one goes flying away. I understand the main chute was still safely stowed on Starliner. https://spaceflightnow.com/2019/11/...arliner-launch/ As a person who has worked the Commercial Crew program for 3 years now, it is incredibly exciting to finally be in the OFT launch campaign. The Booster is erect, and the solids are attached. Next we attach the Launch Vehicle Adapter/Dual Engine Centaur/Interstage Adapter stack. Spacecraft mate is late next week if all goes well, and Wet Dress Rehearsal will be after Thanksgiving. Fingers crossed! |

Atlas V is fully stacked as of today. Started LV testing.

Why does the Starliner have an overhang instead of a traditional boat tail transition to the Centaur?

I assumed aerodynamic issues. I wish they had elaborated on what the loading issues were and how it was configured at the time of the tests.
If I'm reading correctly, the Starliner/Atlas V stack originally had no tapered transition to the Centaur and was just the capsule and SM? The photo inset looks like a boilerplate with a transition, though I don't recall one being launched. I'm assuming it's either an altered image or a failing memory. It would be interesting to find out why they chose the shroud instead of the tapered transition, assuming it originally wasn't going to have either of them.
