This diagram illustrates the Space Shuttle mission sequence. The Space Shuttle was approved as a national program in 1972 and developed through the 1970s. Part spacecraft and part aircraft, the Space Shuttle orbiter, the brain and the heart of the Space Transportation System (STS), required several technological advances, including thousands of insulating tiles able to stand the heat of reentry over the course of many missions, as well as sophisticated engines that could be used again and again without being thrown away. The airplane-like orbiter has three main engines, that burn liquid hydrogen and oxygen stored in the large external tank, the single largest structure in the Shuttle. Attached to the tank are two solid rocket boosters that provide the vehecile with most of the thrust needed for liftoff. Two minutes into the flight, the spent solids drop into the ocean to be recovered and refurbished for reuse, while the orbiter engines continue burning until approximately 8 minutes into the flight. After the mission is completed, the orbiter lands on a runway like an airplane.

KENNEDY SPACE CENTER, FLA. -- The Z1 Integrated Truss Segment (ITS), a major element of the STS-92 mission scheduled for launch aboard Space Shuttle Atlantis in January 1999, is lowered into its workstand for processing in KSC's Space Station Processing Facility (SSPF). The Z-1 truss supports the staged buildup of International Space Station (ISS) on this third scheduled flight for ISS. The Z1 truss allows the temporary installation of the U.S. power module to Node 1. Early in the assembly sequence, the purpose of Z1 is to provide a mounting location for Ku-band and S-band telemetry and extravehicular activity (EVA) equipment. It also provides common berthing mechanism hardcover stowage. In addition, it will assist with the execution of nonpropulsive attitude control. The truss arrived at KSC on Feb. 17 for preflight processing in the SSPF

STS053-09-019 (2 - 9 Dec 1992) --- A medium close-up view of part of the Fluid Acquisition and Resupply Equipment (FARE) onboard the Space Shuttle Discovery. Featured in the mid-deck FARE setup is fluid activity in one of two 12.5-inch spherical tanks made of transparent acrylic. Pictured is the receiver tank. The other tank, out of frame below, is for supplying fluids. The purpose of FARE is to investigate the dynamics of fluid transfer in microgravity and develop methods for transferring vapor-free propellants and other liquids that must be replenished in long-term space systems like satellites, Extended-Duration Orbiters (EDO), and Space Station Freedom. Eight times over an eight-hour test period, the mission specialists conducted the FARE experiment. A sequence of manual valve operations caused pressurized air from the bottles to force fluids from the supply tank to the receiver tank and back again to the supply tank. Baffles in the receiver tank controlled fluid motion during transfer, a fine-mesh screen filtered vapor from the fluid, and the overboard vent removed vapor from the receiver tank as the liquid rose. FARE is managed by NASA's Marshall Space Flight Center (MSFC) in Alabama. The basic equipment was developed by Martin Marietta for the Storable Fluid Management Demonstration. Susan L. Driscoll is the principal investigator.
