		<description><![CDATA[Here si a description of Orion/MPCV from Wikipedia
http://en.wikipedia.org/wiki/Multi-Purpose_Crew_Vehicle

And here is NASA&#039;s website for Orion/MPCV. It&#039;s the same, but units are in pounds instead of kg.
http://www.nasa.gov/pdf/617408main_fs_2011-12-058-jsc_orion_quickfacts.pdf

You have to include total launch mass: capsule, service module, launch abort system, including propellant. Dragon has draco thrusters built into the capsule for launch abort, so they don&#039;t have a separate abort system.

Here is the Wikipedia article for Dragon
http://en.wikipedia.org/wiki/Dragon_(spacecraft)

And the SpaceX web page
http://www.spacex.com/dragon.php

Notice the masses I gave are correct. The SpaceX Dragon has a double hull, just like the Apollo command module and Orion/MPCV. The inner hull for all of them is aluminum, but the outer hull, aka back shell, is different. The SpaceX page just claims their back shell is covered in SpaceX Proprietary Ablative Material. It&#039;s designed to be reusable, so whatever they&#039;re using has to be cleaned so it can be launched again. I still suspect the outer hull (aka back shell) is titanium alloy. Whatever they paint it with will have to be cleaned off and re-painted before another launch.]]></description>

His space advisors, such as they are, advocate NASA ops as an element of national security and he has reiterated a strong defense stance recently in a nicely timed speech over Memorial Day in San Diego, home of multiple DoD contractors and installations, down the coast from his LaJolla beachfront home. The next potential  slapdpwn will be the unconstitutional ruling of Obamacare.  If Obama wants to win, he&#039;d better firm up his messaging and torpedo Romney as another laisse-faire minded Hoover against all things FDR. The nation needs a Captain Kirk. It has a Mr. Spock. And the alternative is looking more and more like a Commadore Decker w/an elevator for his cars in his home.

&lt;i&gt;&quot;Falcon 9 Heavy can only life Dragon to Mars. Dragon is a wonderful spacecraft, but too small for a 6 month trip to Mars. I could give you my architecture, which can be done with existing launch vehicles, and Dragon is one component. But Congress isnâ€™t listening. What do you propose?&lt;/i&gt;
A NASA study proposes something entirely different from what you outline.  The assembly in orbit (using the experience in orbital assembly we acquired through ISS) of a &quot;true&quot; space ship that never lands for deep space missions such as one to Mars.

Hmmm. Recalls can work. Ask the &#039;idiots&#039; aka your fellow Americans who successfully recalled Gov. Davis in California. A sophisticated view should tell you that this cycle is shaping up to be Obama&#039;s to lose rather than Romney&#039;s to win-- and Obama isn&#039;t helping him self much of late. The sloppy messaging, unfavorable economic data and the looming  unconstitutionality ruling of Obamacare are dominos falling and failing the incumbant just five months out. Romney&#039;s VP selection will be his next benchmark. But his space policy remains nebulous at best and far down his agenda at worst.

&quot;&lt;i&gt;I have said Energia is a â€œsafe, cheaper and more practical alternatives that can be implemented soonerâ€. Falcon 9 Heavy can only life Dragon to Mars.&lt;/i&gt;&quot;

You are falling into the same trap that others have - you think serially instead of in parallel.

The Apollo Moon missions were an example of serial thinking.  One 119mt HLV launch to lift everything needed for the mission.

The 450mt ISS is an example of thinking in parallel.  Many rockets and spacecraft were used to assemble the station and to keep it operating.

So it will be with any vehicle we build for going to Mars - it will be built out of modular components, and it will be moved on it&#039;s way by reusable boosters that were lifted individually.

&quot;&lt;i&gt;What do you propose?&lt;/i&gt;&quot;

Energia was too small to do everything in one launch for a full-up Mars mission, as was the Ares V, and as is the SLS.  Modular construction using many low-cost &amp; existing rockets is the way to go.

Our Congress will come around soon, just as they came to their senses with the over-budget, behind-schedule Constellation program.]]></description>
