...days in the space station Mir, a prototype of one from which the Soviets hope to send men to Mars before the end of the century. The same day, NASA announced that part of a newly designed booster rocket had failed during a test firing at a Morton Thiokol plant near Brigham City, Utah, causing an undetermined delay in the faltering effort to resume U.S. manned space missions. At the same plant, five workers were killed when nearly 100,000 lbs. of solid rocket propellant for an MX missile section accidentally ignited. Since a similar fueling procedure is used...
...boot ring had been redesigned because an earlier type had eroded on several missions. Morton Thiokol officials said a different type of nozzle joint had been tested successfully in August and could be reinstalled. "We have a parallel design, and we also have some rings of a different configuration on the shelf," said John Thomas, a NASA engineer who began examining the failure. "What we have to do is understand exactly what happened so we can clear this ring or another...
Fire and smoke streamed across the desert outside Brigham City, Utah, last week as Morton Thiokol successfully fired its redesigned booster rocket for NASA's shuttle fleet. With the test, the crippled shuttle program cleared its first major technical hurdle in resuming flights, now set for next summer...
...tests. Company engineers are now examining for charring or erosionthe revamped joints that connect segments of the booster. Those signs indicate leakage of burning gases, the problem that led to the Challenger explosion 19 months ago. More stringent testing lies ahead. Still, officials of the space agency and Morton Thiokol were ecstatic. Said NASA Associate Administrator Richard Truly: "We waited a long time to see this...
...scorched a Utah hillside last week. Jubilation was in order: the firing marked the first full- scale test of the space shuttle's revamped solid rocket booster since last year's Challenger explosion. After a government commission pinned the tragedy on faulty seals in the booster, manufactured by Morton Thiokol, the company returned to the drawing board. Last week's firing, the first of six, tested new electrical heaters and reinforcing bands on the booster's joints. "We've taken a real bashing by the press," said Morton Thiokol Engineer Allan McDonald, who heads the redesign. "This proves...
