The DIRECT launch-system was a proposal for an alternative to the Ares I and the Ares V launcher.
Instead of using two launchers the idea was to replace them with a single launch vehicle named "Jupiter". With two different configurations it would have been able to perform both crew and cargo missions.
Both variants was planned to use a pair of Space Shuttle Solid Rocket Boosters unchanged from their configuration as used on the Shuttle. Mounted between those is the Jupiter Core Stage, based very closely on the original Space Shuttle External Tank, modified to mount payloads on top and a set of engines underneath.
When NASA was authorized in 2010 to mandating work on the Space Launch System Heavy Lift Launch Vehicle, the DIRECT Team declared their effort a success and disbanded.
About the model
Later the models was put on display in the library at NASA-HQ in D.C. and have been since January of 2009.
Thanks to "Lancer" to let me host his two historic important models of the DIRECT launch system.
