Yes, something like this would be *very* useful indeed. We certainly won't improve our chances of making it past the Singularity just by talking about it. This "space program" to create at least one offplanet habitat which could sustain a group of, say, 100-1000 people (depending on the interest in this project) long enough for them to transcend could be part of a greater "Ascension Initiative" (or AI for short), which might also include:

-An uploading node, along the lines of Joe Strout's proposal ( -A "survivalist" node that prepares one or more "nuke-proof" shelters which could do the same as the offplanet habitat in case of a severe society-crippling, non-nanotech war or disaster (a fully self-sufficient cryonics facility should always be included, for obvious reasons).
-A nanotech research node as, which might, among other things, try to design some basic software for replicators to make tools, structures, food etc. which will be needed for the creation and maintenance of viable space habitats. -A financial node to (partially) fund all of the above, and anything else that may be necessary.

Needless to say, all of this would by no means guarantee success, but at least we could say that we've *tried*.
