Delta

Goddard Space Flight Center displays a Delta (sometimes called a Thor-Able) in its Rocket Garden. Google Maps link.

The early Deltas consisted of a Thor missile as its first stage with an Able upper stage (the Able upper stage was a modified second stage from the Vanguard rocket, which attempted but failed to launch the first American satellite). The Delta family, much evolved, is still launching payloads today.

The visitor center also displays a Delta payload fairing.

I have additional photos of a similar Delta in the Kennedy Space Center rocket garden.

Also see my page with additional information on the Delta launch vehicle.
