I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

1. THIO_030519_42.JPG: TU-772 Space Shuttle Reusable Solid Rocket Motor. Measures 149 feet in length, 12 feet 2 inches in diameter. "The Space Shuttle Reusable Solid Rocket Motor (RSRM) is the largest man-rated solid rocket motor ever flown and the only booster capable of recovery and reuse. Developed for NASA by Thiokol in the mid-1970's, the RSRM was successfully static tested on July 18 1977. During the first 122 seconds of each flight, two RSRM's provide 80 percent of the thrust needed to accelerate the Shuttle to a speed of 3,094 miles per hour before separating from the orbiter and external tank and an altitude of 24 nautical miles. Nearly seven minutes after separation, the spent boosters parachute into the Atlantic Ocean approximately 140 nautical miles downrange from Kennedy Space Center. The recovered boosters are disassembled in Florida and returned to Thiokol's Space Operations plant in Utah, where they are refurbished for use on future Space Shuttle flights."

Wikipedia Description: Thiokol
From Wikipedia, the free encyclopedia

Thiokol (variously Thiokol Chemical Company, Morton-Thiokol Inc., Cordant Technologies Inc., Thiokol Propulsion, AIC Group, ATK Thiokol; currently ATK Launch Systems Group) is a U.S. corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur (Te?? "theio") and glue (????a "kolla"), an allusion to the company's initial product.

The Thiokol Chemical Company was founded in 1929. Its initial business was a range of synthetic rubber and polymer sealants, and Thiokol was a major supplier of liquid polymer sealants during World War II. When scientists at the Jet Propulsion Laboratory discovered Thiokol's polymers made ideal rocket fuels, Thiokol moved into the new field, opening laboratories at Elkton, Maryland, and later production facilities at Elkton and at Redstone Arsenal in Huntsville, Alabama. Huntsville produced the XM33 Pollux, TX-18 Falcon, and TX-135 Nike-Zeus systems. It closed in 1996. In the mid 1950s the company bought extensive lands in Utah for its rocket test range, and continues to have major operations in the state, at Magna and Promontory (home of the Space Shuttle's SRB), and its current headquarters at Brigham City. As of 2005 the company employs over 15,000 people worldwide and records annual sales of around $ 840 million.

Company history:

* 1929: Thiokol Chemical Company founded.
* 1949: Thiokol produce the TX-18 Falcon missile, the world's first solid-fueled missile system.
* 1957: In anticipation of the forthcoming Minuteman contract, the company builds its plant at Brigham City, Utah.
* 1957: Thiokol Huntsville builds XM33 Pollux missile
* 1958: Merger with Reaction Motors Inc. (RMI), makers of liquid propellant rocket motor systems.
* 1958: Thiokol awarded contract to build the TU-122 rocket motor for the first stage of the LGM-30 Minuteman ICBM system.
* 1959: Thiokol Huntsville produces CASTOR strap-on booster rocket, used on the Atlas rocket.
* 1974: Thiokol wins the contract to build the solid rocket booster (SRB) for the Space Shuttle
* 1978: The company sells its ski lift division to CTEC and its snow equipment division to Logan Manufacturing Company (LMC), owned by John DeLorean.
* 1980: Acquires Carlisle Chemical Company of Cincinnati, Ohio.
* 1982: Thiokol merges with Morton-Norwich products (owners of the Morton Salt concern, the Simoniz automotive products brand, and various chemical concerns). The merged company is called Morton Thiokol Incorporated (MTI).
* 1986: An O-ring fault in an MTI SRB destroys space shuttle Challenger in flight
* 1989: Morton Thiokol splits, with most of the chemical concern going with Morton. The propulsion systems division becomes Thiokol Inc.
* 1998: Thiokol changes name to Cordant Technologies.
* 1998: Thiokol branded polymer products purchased by PolySpec L.P., a Houston based manufacturer of Industrial Coatings, Marine Decking, and Subsea Insulation products.
* 2000: Thiokol merges with two divisions of Alcoa and with Howmet Castings and Huck Fasteners to become AIC Group (Alcoa Industrial Components).
* 2001: Alliant Techsystems (ATK) Inc. (a company formed when Honeywell spun off its defense division) spends $2.9 billion buying Thiokol and related businesses from AIC/Alcoa. ATK built the third stage of the Trident missile and had earlier bought Hercules Aerospace Co., builder of the second stage. With the purchase of Thiokol, who make the missile's first stage, ATK controls the lion's share of the US solid-rocket market.
* 2005, Thiokol wins the contract to produce the Ares I launch vehicle first stage for NASA's Project Constellation.
* 2006, Alliant Techsystems (ATK) Inc. renamed ATK-Thiokol to ATK Launch Systems Group.

Products:

Products made by the aerospace divisions of RMI and Thiokol include motors used in Subroc, the Pershing missile, the Peacekeeper missile, Poseidon missile, Minuteman missile, and the Trident I and Trident II missiles. Thiokol produces powerplants for numerous U.S. military missile systems, including AIM-9 Sidewinder, AGM-88 HARM, AGM-65 Maverick, AGM-69 SRAM, and AIR-2 Genie.

Thiokol also produced a variety of liquid and solid rocket motors for the US space program, including deorbit motors for the Mercury and Gemini programs, rocket stages and separation rocket motors for the Apollo program, motors for the Pioneer, Surveyor, Viking, Voyager, and Magellan missions, updated CASTOR boosters for the Delta rocket, and the Space Shuttle Solid Rocket Booster. Reaction Motors powerplants propelled the X-1 and X-15 aircraft, and later Thiokol technologies were also used in the private Tier One manned spaceplane. On March 1, 2006, NASA announced that Thiokol will be the prime contractor for the new Crew Launch Vehicle (CLV), to be known as the Ares I, which will put the Orion spacecraft (formerly known as the "Crew Exploration Vehicle") into low earth orbit, along with the five-segment SRBs for the heavy-lift Cargo Launch Vehicle (CaLV), known as the Ares V.

In addition to ski lifts, Thiokol produced a range of equipment for ski resorts including snowcats and snow grooming vehicles. These businesses were spun off in 1978 when the company restructured itself to concentrate on its rocket products and related technologies. John Z. DeLorean purchased the Thiokol snowcat operation and renamed it DMC. DMC continued to manufacture snowcats until 1988, when the company was renamed LMC. LMC continued making snowcats for 12 more years but ceased operations in 2000. Thiokol produced snow vehicles with a wide range of capabilities and duties. They company also produced several utility based vehicles based on their snowcat tracked vehicle, in addition to larger snow grooming machines suitable for use on steep ski-slopes. Thiokol machines were used in ski resorts, operated by the USAF in Alaska and other northern regions, and are now popular with private owners as dependable snowcats and for all terrain transport.

Thiokol pioneered the short-burn rocket motors used in aircraft ejector seats. The company also produced a number of the earliest practical airbag systems, building the high-speed sodium azide exothermic gas generators used to inflate the bags. Thiokol bags were first used in U.S. military aircraft, before being adapted to space exploration (Mars Pathfinder bounced down on Mars on Thiokol airbags) and automotive airbags. Thiokol's generators form the core of more than 60% of airbags sold worldwide.

Space Shuttle Challenger Disaster:

The Space Shuttle Challenger accident occurred on the morning of January 28, 1986, at 11:39 EST, when Space Shuttle Challenger disintegrated 73 seconds into its flight

Later in 1986, the Rogers Commission and the United States House Committee on Science found that the Challenger accident was caused by a failure in an O-ring Morton-Thiokol had provided. The O-ring failed to seal a joint on the right solid rocket booster, which allowed pressurized hot gasses and eventually flame to "blow by" the O-ring and make contact with the adjacent external tank, causing structural failure. The failure of the Viton O-rings was attributed to a faulty design, whose performance could be too easily compromised by factors including the low temperature on the day of launch. Thiokol engineers informed NASA of this problem and recommended a delay of the launch until the temperature was warmer, but because the launch had already been delayed by several days, NASA decided to go ahead with it.
