The latest Armadillo Aerospace project update has the usual detailed technical descriptions of engine and other vehicle work. At the end, though, John Carmack includes some illustrations of a proposed single-person suborbital vehicle, using a “six pack” of modules.

Carmack warns not to “read too many technical details into these concept renderings”, but it still looks pretty interesting. Half the Armadillo team will be at Space Access ‘08 to provide more details on this concept and their other work.
