A second study for NASA´s manned asteroid mission?

The study would be to update the original work following the more detailed work that has been done on the Ares launchers and Orion since. The original study used the Orion 604, the last NASA-only design and the CEV is now at design “607 or 608”

And after a year of briefing various people the next presentation will be given to the US National Research Council on 9 June

The two astronauts that would go, between the Orion and LSAM Korsmeyer said that the habitable volume would be similar to Russia’s first Salyut and of the radiation issues he said: “We have no idea what that really does being outside the magnetosphere.”

The study looked at four different launch options with two pictured here. The four are, an Orion launched by Ares V; a Moon mission type dual launch with Ares V launching the EDS and a prototype Altair and Ares I lofting Orion; an Ares IV launching an Orion; and in another dual launch situation a Ares I launching Orion while an EELV launches a Centaur upper stage that would dock with Orion and push the CEV out to the NEO
