A space research laboratory on a space shuttle that doubles the living space and quadruples the room for payload hardware. The module is 4 m in diameter and 2.7 m long, with a payload capacity of 2 160 kg. The modules are built by SPACEHAB, Inc. of Arlington, Virginia, who pay NASA to launch them. The company then leases experiment space to NASA, governmental agencies, private industry, universities, and research institutions. The first Spacehab was launched on 21 June 1993 aboard the space shuttle Endeavour and carried 22 experiments. The second Spacehab was launched on 3 February 1994 aboard the space shuttle Discovery, carrying 13 experiments that included crystal growth research to develop improved semiconductors. The third Spacehab flight was on 3 February 1995 on board Discovery. The latter Spacehab was an improved version with a camera to assist the mission's rendezvous docking with the Russian space station Mir.
