Marcia: What did you do to refurb the Dragon. How much is original? Will next Dragon be reused version?
Hans: Majority of Dragon (hull) is same. When Dragon came back, we inspected it against its qualification specs, and we made sure all items had enough "life" for this mission. Same idea to what we do with the booster. Results shared with NASA and reviewed together. Some cases (FEW), there were components that needed to be swapped out.
MAJORITY of this Dragon has been in space.
Next Dragon is new from what Hans remembers.
Some batteries (because of sea water intrusion) were replaced. Thrusters are the same to CRS-4.
