Stennis Space Center MS (SPX) Oct 05, 2021 The latest RS-25 engine test at NASA's Stennis Space Center completed the Retrofit-2 test series, which validated modernized, lower-cost components for new [...]

TEST-FIRING THE SPACE SHUTTLE ENGINES More than 1500 dramatic live firings beneath 12-story-tall test stands have wrung problems out of the Space Shuttle engines, as NASA and Rocketdyne engineers collected [...]

The NASA/Boeing-Rocket dyne Space Shuttle Main Engine (SSME) project is correcting flaws in critical Honeywell SSME electronic components, which otherwise might have caused a dangerous launch pad abort. The Flight Readiness Review is set for June 29-30, 2005, and about 1,600 electronic capacitor components in Honeywell computer controllers on shuttle main engines are being purged because of manufacturing defects.

Many of us heat our homes with oil, and right around now is when we buy some. I used wood for 13 years, believing the old saying that 'wood heats [...]

HUNTSVILLE, Ala., March 28 (SPX) -- Did you know that NASA's Space Shuttle Solid Rocket Boosters trace their roots to 12th century China, where the first rockets were developed for [...]

For the first time, the risky task of recovering a space shuttle booster from the Atlantic Ocean has been done with the aid of a mini-submarine. Normally, the job is [...]

Will tomorrow's propulsion systems meet the challenge of interstellar travel? Cleveland's NASA Glenn Research Center is pursuing a systematic study of emerging scientific theories on propulsion. One is zeropoint energy, […]

Thiokol [CDD] and NASA have completed negotiating a $1.73 billion contract for 73 Space Shuttle Reusable Solid Rocket Motors. The Space Shuttle uses two of these motors per mission as [...]

The combination of ConProTec and RTG adhesive products aided in the development of reusable solid rocket motors for NASA's Space Shuttles. The adhesive bond joining phenolic materials to metal support [...]

A review of the STS-115 Atlantis crew during return-to-launch-site (RTLS) and other abort training in the shuttle mission simulator as they prepared for liftoff in late August 2006 is presented. An RTLS abort is a high-risk element of shuttle launches since the program's inception, but with improved software and more robust space shuttle main engines (SSMEs), an RTLS is far more likely to end in a safe landing now than before.

Planners on the Exploration Systems Architecture Study (ESAS) have chosen the Pratt and Whitney Rocketdyne space shuttle main engine (SSME) and the ATK reusable solid rocket motor (RSRM) to do the heavy lifting on the way back to the Moon. The plan was aimed at saving time and money on development and also proposes to produce methane fuel on Mars in order to save weight on the outward journey to Mars.

The Space Shuttle Discovery will be powered by the Block 1 SSME upgrade engine when it flies on its STS 70 mission in Jun. 1995. The new engine, which replaces a Rocketdyne engine, will use a Pratt and Whitney Alternate High Pressure Oxidizer Turbopump. It also has a single-coil heat exchanger, which pressurizes oxygen with the help of a hot gas system in the powerhead. However, the performance of the engine, in terms of specific impulse, has yet to be determined.

HANCOCK COUNTY -- Space Shuttle Endeavour, headed for retirement in California, is scheduled to perform low flyovers--as low as 1,500 feet--as it passes NASA facilities in Mississippi and Louisiana. Stennis [...]

A test firing of the third engine in the space shuttle Endeavor has been scheduled. The engine caused an aborted launch on Aug 18, 1994, due to a computer command. Engineers suspect either a fuel flow meter, bleed valve or fuel supply block.

Deep-space travel may come closer within reach with new vehicle propulsion technologies based on fusion energy. At the University of Alabama, Huntsville, researchers working on the Plasmoid Thruster Experiment are […]

HANCOCK COUNTY -- Engineers at NASA's John C. Stennis Space Center (SSC) have tested the final of three Space Shuttle main engines (SSMEs) that will carry the next Space Shuttle [...]

The John C. Stennis Space Center in Hancock County is well-known as the country's largest rocket test facility and the place where, since 1975, all space shuttle main engines that [...]

NASA has withdrawn space shuttle main engines from service after finding high-cycle fatigue cracks in one engine's follow-on fuel pumps. The pump was to be part of the Block 2 upgrade that will be used on shuttle flights starting in 1997. Design similarities between the pump and the Pratt & Whitney high-pressure oxidizer turbopump used on the Block 1 engine has raised doubts about the latter. These doubts could delay the shuttle's May 16, 1996, flight.

An independent task force called the space station main engine safe for flight if and only if all special controls are followed, but recommended improvements to reduce dependence on those procedures. Specific recommendations are listed.

Thiokol Corp. Thiokol Corp. has been awarded a $2.6 billion NASA contract for the continued production of space shuttle solid-rocket booster motors. The contract will extend existing Thiokol Space Operations [...]
