The DragonFly EIS lists a dry mass of 6,350.3 kg. How close that is to a crew V2 is up for discussion.

This AmericaSpace article gives CST-100 a mass of 10 tons.

Dual Centaur should add about 2500kg.

Wonder where the huge difference in mass comes from, especially since the CST 100 does not seem to be any more capable than the Dragon V2.

It is obvious.  Propellant.  Dry vs wet mass

Is it?

It is right in the words:  "The DragonFly EIS lists a dry mass of 6,350.3 kg"

Also missing the trunk.

CST-100 is also larger in diameter and Dragon's PICA-X heat shield is very light (Gen 1 = 0.27 g/cm^3)**

Centennial, Colo., (July 7, 2014) – United Launch Alliance (ULA) recently completed a Critical Design Review (CDR) of the launch site accommodations that will support commercial crew launches of Boeing’s Crew Space Transportation (CST) -100 at Space Launch Complex 41 (SLC-41) in Florida.

The CDR, supported by Boeing, NASA, and the Air Force, approved the design for the Crew Access Tower, Crew Access Arm as well as the White Room that will allow the flight crews the ability to safely ingress and egress Boeing’s CST-100 crew module for launch. In addition, the team reviewed the conceptual design of the emergency egress system which is similar in design to the space shuttle basket escape system.

No mention of DC support in the new tower.

no but some news in there....

“This was a critical milestone to ensure all elements are in place to begin the construction as early as this fall

Once the work begins at SLC-41, the construction of the new elements to support human spaceflight will take approximately 18 months and will not impact any scheduled launches at the pad.   

“The beauty of the plan is the integrated fashion in which the construction will be handled,” said Plese. “We will be constructing each segment of the new tower and access arm at an off-site location and performing assembly at the pad between launches. This allows ULA to continue its full manifest of launches from SLC-41 while preparing the pad for future commercial crew missions.”


Among the questions
1) anyone know when shovel turning day is?

"ensure all elements are in place to begin the construction as early as"

Means:

"Construction begins as soon as the check clears"

Unplanned.  Will only happen if Boeing wins.

Do the crew board capsule before or after LV is fuelled?.

What if SNC wins? They will need a tower to launch from an Atlas V.

That is a fine looking spacecraft.  Seems very reminiscent of the original plans for Orbital Space Plane, isn't it?  How does this compare to Saturn IB?

Here is the rest of the image from their facebook page.
Thanks for finding that. Some things look elegant and some, not so much. This would be one of the latter, I'm afraid. Something just seems really ungainly. Not that it matters at all.

Mulholland won't say how much less it will cost NASA to fly the CST-100 than it currently pays the Russians, only to say it will be "significantly below" $70 million a seat. He cites competitive reasons for not disclosing a figure. He also won't say how much money Boeing has invested of its own money in developing the space taxi, though he says NASA's $460 million investment "has paid the preponderance of the development work to date."
