FlightGlobal.com details Boeing's commercial crew bid with the CST-100 capsule.
"It's really in two phases," says John Mulholland, the capsule's
programme manager, of the latest bid. "There's a 21-month base period
where we'll accomplish our critical design review and a significant
amount of risk reduction design testing, and we will culminate at the
end of the option period with a two-crew flight test."
Particularly interesting is that Boeing is not totally committed to the Atlas V as the launch vehicle.
Despite Boeing's relation to the Atlas - ULA is a joint Lockheed/Boeing
business venture -- Mulholland confirms that discussions have been held
with SpaceX and ATK for possible launches when CCiCap transitions to a
services contract in 2016. Both SpaceX and ATK have submitted bids for
CCiCap and compete with ULA for launch business.
