[FPSPACE] Dual Orion capsules studied for manned asteroid missions

[David Portree]

Hi, John:

 

Yeah, it's like that. "The amazing Orion capsule - a thousand household uses - accept no substitutes."

 

>From a life sciences point of view, does the dual Orion concept make sense? I would have thought that the two capsules would provide inadequate radiation protection and living volume for a two-to-six-month mission beyond LEO even if they carried only two astronauts - but maybe I'm being too pessimistic.

My first thought was, "leave it to the prime contractor to suggest ways to increase sales of their product -- and exclude the competitor's product (the Altair)."


My second thought was, "why not?" Remember the fleet of LM variants that Grumman proposed to produce?  And North American had pages of viewgraph charts showing command modules in many possible applications, such as the "comlab" LEO laboratory. And McDonnell-Douglas offered a variant of its Gemini capsule for a direct lunar mission displacing both North American and Grumman products.


Desperation or just clever marketing?

Just because an asteroid passes one million kilometers from Earth doesn't mean one could reach it as easily or as quickly as an L point. Furthermore, not all asteroids are worth reaching, and this mission would focus on which are accessible by straining the Orion system, not on the value of the targets; basically, it'd be a stunt. Finally, for the cost of this stunt mission, we could send robot explorers to a dozen more interesting asteroids.
 
You'll note that I'm not talking about the mission concept; this has more fundamental problems that kill it before we get that far. We could come up with a grand design for launching a manned spacecraft to Antarctica, but why would we want to, since there are more sensible ways to do the job?

Dual Orion capsules studied for manned asteroid missions

A manned asteroid mission using two Orion spacecraft, docked nose-to-nose to form a 50-ton deep space vehicle, is being studied by Lockheed Martin Space Systems as an alternative to resumption of U.S. lunar landing missions. 
 
The Orion asteroid mission concept is being unveiled just as the Presidential committee reviewing U.S. human space flight is citing asteroid missions after 2020 as a less costly alternative to NASA's proposed lunar landing infrastructure. 
Results of the review will be briefed to President Obama by Norman Augustine, committee chairman, by the end of August.
