Crew access arm, etc discussion
« on: 08/17/2018 03:35 pm »
Just saw a news item about the crew access arm being revealed from under the tent it was being welded and assembled. Supposedly to be completed by the end of August. Really? (Teslarati)

What needs to be done to provide crew access to Dragon?

Obviously bolt on the arm that's being built.

What is the status of modifications to the existing tower?

Will SpaceX have an emergency escape system from the tower?

(That's needed for working around a million kilos of fuel and oxidizer with no enclosing protection system. With the crew loaded in an armed escape pod before fuel loading, and remaining in that armed escape pod until the fuel is gone by launch, or by abort and fuel and oxidizer drained back to safe the pad, is there any reason for mere humans to be on the tower when there is a risk of being roasted?)

Dry runs of erecting rocket, swinging the arm, loading crew, swinging the arm back and forth, unloading the crew, etc.

If there is an abort, how long to drain the fuel and safe everything so ground crew can start getting access to the arm to remove the crew?

What else?

Will Elon pop up with a Tesla bus to deliver the crew to the launch pad from where ever the crew goes through final inspection, isolation, suit up, etc? Or does NASA have the bus, etc?

What is the crew timeline from waking up to floating?

There are existing threads for discussing most of this.  The Pad 39A mods (including the crew access arm, emergency escape system, etc.) are already being discussed in:  Pad 39A - SpaceX Falcon 9 and Falcon Heavy - Post Transition (Thread 4)
