Pratt & Whitney Rocketdyne's Jeff Hansell, right, explains functions of a space shuttle main engine to Pearl River Community College Aviation Maintenance Technology Program students. Christopher Bryon, left, of Bay St. Louis, Ret Tolar of Kiln, Dan Holston of Baxterville and Billy Zugg of Long Beach took a recent tour of the SSME Processing Facility and the E-1 Test Complex at Stennis Space Center in South Mississippi. The students attend class adjacent to the Stennis International Airport tarmac in Kiln, where they get hands-on experience. PRCC's program prepares students to be responsible for the inspection, repair and maintenance of technologically advanced aircraft. A contractor to NASA, Pratt & Whitney Rocketdyne in Canoga Park, Calif., manufactures the space shuttle main engine and its high-pressure turbo pumps. SSC was established in the 1960s to test the huge engines for the Saturn V moon rockets. Now 40 years later, the center tests every main engine for the space shuttle, and is America's largest rocket engine test complex. SSC will soon begin testing the rocket engines that will power spacecraft carrying Americans back to the moon and on to Mars.

Prior to its launch in April 1990, the Hubble Space Telescope (HST) went through years of development and testing. The HST was the first of its kind and the scientific community could only imagine the fruits of their collective labors. However, prior to its launch, more practical procedures, such as astronaut training, had to be developed. As the HST was to remain in orbit for years, it became apparent that on-orbit maintenance routines would have to be developed. The best facility to develop these maintenance practices was at the Neutral Buoyancy Simulator (NBS) at the Marshall Space Flight Center (MSFC). The NBS provided mock-ups of the HST (in sections), a Remote Manipulator System (RMS), and a shuttle's cargo bay pallet. This real life scenario provided scientists, engineers, and astronauts a practical environment to work out any problems with a plarned on-orbit maintenance mission. Pictured is an astronaut in training with a mock-up section of the HST, practicing using tools especially designed for the task being performed.
