A fairly significant mission for SLS/Orion that couldn't be done with other available launch vehicles. Right now SLS just seems like a slow and expensive path to nowhere.
I think most of the posters here did not read the OP very carefully. He said "if you think the Orion/SLS is a good idea." Most of the posters seem to believe Orion/SLS is a bad idea, and are describing what it would take to change their minds.
If you think the Orion/SLS is a good idea, what new information would make you change your mind?Same question for those opposed to Orion/SLS.
I have a hard time supporting SLS due to my taxpaying cost.
