The fourth full-duration test firing of NASA's redesigned Space Shuttle solid rocket motor was conducted at Morton Thiokol's Space Operations facility near Brigham City, Utah. The test was part of the Shuttle motor redesign program. The 126-foot-long, 1.2-million-pound motor, designated Qualification Motor-7 (QM-7), underwent a full-duration, horizontal test firing of two minutes. After a preliminary examination of the fired motor, NASA and Morton Thiokol officials declared the test an apparent success. The exercise involved the first use of a new test stand at Morton Thiokol. One remaining full-duration test, Production Verification Motor-1 (PVM-1), would be conducted in July, prior to the next Space Shuttle flight. (NASA Release 88-7; NY Times, Jun 15/88)
