Apex RV

American logistics spacecraft. Study 2005. Spacehab's Apex design provided a family of launcher-neutral maneuverable spacecraft that could be used for resupply of the ISS and return of payloads to earth.

The Apex design was available to both commercial and government markets. The Apex vehicles were available in three different configurations: one-, three-, and four-meter diameter spacecraft. The smallest Apex could carry up to 300 kilograms to LEO, with the larger two spacecraft carrying cargo of up to 1,300 and 6,000 kilogram, respectively. The largest Apex vehicle could be outfitted to carry crew. The first flight of the Apex was planned for 2007. The vehicle was designed to be launcher-neutral, with an open architecture capable of serving different markets.
