Media Advisory: 05-101

What: NASA’s Space Shuttle program will test its first Production Rate Motor, a full-scale Reusable Solid Rocket Motor, at the facilities of ATK Thiokol Inc., an Alliant Techsystems company, in Promontory, Utah. The test is a demonstration of the process, material and design changes made to the 10 rocket motors produced during the past two years. The motor test also will measure 48 objectives, including the performance of sensors that read and retain detailed information on pressures generated in a rocket motor during a Shuttle launch.

The Shuttle's Reusable Solid Rocket Motor is the largest solid rocket motor ever flown, the only one rated for human flight and the first designed for reuse. It is the primary component of the Shuttle's twin Solid Rocket Boosters. These solid propellant rockets take the Shuttle to an altitude of 28 miles at a speed of 3,094 mph before they separate and fall into the ocean to be retrieved, then refurbished and prepared for another flight.

When: Thursday, June 23, 1 p.m. MDT

Where: Facilities of ATK Thiokol Inc., an Alliant Techsystems company, at Promontory, Utah

To Attend: To attend the firing, media representatives must register with Melodie de Guibert of ATK Thiokol by telephoning (435) 863-3169 no later than 1 p.m. MDT Wednesday, June 22
