NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama, has begun a series of engine tests on the Reaction Control Engine developed by TRW Space and Electronics for NASA's Space Launch Initiative (SLI). SLI is a technology development effort aimed at improving the safety, reliability, and cost effectiveness of space travel for reusable launch vehicles. The engine in this photo, the first engine tested at MSFC that includes SLI technology, was tested for two seconds at a chamber pressure of 185 pounds per square inch absolute (psia). Propellants used were liquid oxygen as an oxidizer and liquid hydrogen as fuel. Designed to maneuver vehicles in orbit, the engine is used as an auxiliary propulsion system for docking, reentry, fine-pointing, and orbit transfer while the vehicle is in orbit. The Reaction Control Engine has two unique features. It uses nontoxic chemicals as propellants, which creates a safer environment with less maintenance and quicker turnaround time between missions, and it operates in dual thrust modes, combining two engine functions into one engine. The engine operates at both 25 and 1,000 pounds of force, reducing overall propulsion weight and allowing vehicles to easily maneuver in space. The force of low level thrust allows the vehicle to fine-point maneuver and dock, while the force of the high level thrust is used for reentry, orbital transfer, and course positioning.

Engineers at the Marshall Space Flight Center (MSFC) have begun a series of engine tests on a new breed of space propulsion: a Reaction Control Engine developed for the Space Launch Initiative (SLI). The engine, developed by TRW Space and Electronics of Redondo Beach, California, is an auxiliary propulsion engine designed to maneuver vehicles in orbit. It is used for docking, reentry, attitude control, and fine-pointing while the vehicle is in orbit. The engine uses nontoxic chemicals as propellants, a feature that creates a safer environment for ground operators, lowers cost, and increases efficiency with less maintenance and quicker turnaround time between missions. Testing includes 30 hot-firings. This photograph shows the first engine test performed at MSFC that includes SLI technology. Another unique feature of the Reaction Control Engine is that it operates at dual thrust modes, combining two engine functions into one engine. The engine operates at both 25 and 1,000 pounds of force, reducing overall propulsion weight and allowing vehicles to easily maneuver in space. The low-level thrust of 25 pounds of force allows the vehicle to fine-point maneuver and dock while the high-level thrust of 1,000 pounds of force is used for reentry, orbit transfer, and coarse positioning. SLI is a NASA-wide research and development program, managed by the MSFC, designed to improve safety, reliability, and cost effectiveness of space travel for second generation reusable launch vehicles.

KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility, the left-hand Orbital Maneuvering System (OMS) pod is maneuvered toward the engine interfaces on the orbiter Discovery for installation. The Orbital Maneuvering System provides the thrust for orbit insertion, orbit circularization, orbit transfer, rendezvous, deorbit, abort to orbit and abort once around. It can provide up to 1,000 pounds of propellant to the aft reaction control system. Each pod contains one OMS engine and the hardware needed to pressurize, store and distribute the propellants to perform the velocity maneuvers.

KENNEDY SPACE CENTER, FLA. -- Clyde Parrish, a NASA/KSC engineer, explains how the fertilizer scrubber control panel (center) works to turn nitrogen tetroxide vapor into fertilizer, potassium hydroxide. Parrish developed the system, which uses a "scrubber," to capture nitrogen tetroxide vapor that develops as a by-product when it is transferred from ground storage tanks into the Shuttle storage tanks. Nitrogen tetroxide is used as the oxidizer for the hypergolic propellant in the Shuttle's on-orbit reaction control system. The scrubber then uses hydrogen peroxide to produce nitric acid, which, after adding potassium hydroxide, converts to potassium nitrate. The resulting fertilizer will be used on the orange groves that KSC leases to outside companies

KENNEDY SPACE CENTER, FLA. -- Inside the Vehicle Assembly Building, main engine No. 3 (bottom right) is being removed from Space Shuttle Discovery. Above it are (left) the Orbital Maneuvering System (OMS) engine, the reaction control thrusters (right), and the OMS pod (top). Last week, Shuttle managers determined that the engine was not acceptable for flight because a half-inch-long broken drill bit is lodged in the engine's coolant cavity. Therefore, the engine is being replaced. The Shuttle is expected to roll out to the pad at 2 a.m. Saturday morning, Nov. 13. The STS-103 launch is now targeted for Dec. 6 at 2:37 a.m. EST. The 10-day mission is expected to conclude at KSC on Dec. 16 with a 12:45 a.m. landing

Each year, the NESC produces the NESC Technical Update, which highlights two or three individuals from each Center and includes assessments throughout the year. Because of the critical contributions to the NESC mission this year, Rob Jankovsky, NESC Chief Engineer at GRC, chose two individuals to be highlighted. This year, it is Andrew Ring and Michael Cooper. The Lead Analyst for GRC’s Chemical and Thermal Propulsion Systems branch, Mr. Michael Cooper, is supporting NESC test operations on reaction control system thrusters for Gateway’s Power & Propulsion Element. “These thrusters are small with few moving parts, but the heat and mass transfers involved are very complex,” he said. The test campaign is putting the thrusters through a rigorous profile to simulate the lifetime they will experience over decades in space. Mr. Cooper is analyzing test data gathered on chamber pressure, temperature, flow rates, and more to develop models on thruster performance. He also built the tool that read in that data from the test stand instrumentation. Photo Credit: (NASA/Sara Lowthian-Hanna)

CAPE CANAVERAL, Fla. – An orbital maneuvering system, or OMS, pod hovers above its transporter in Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida. The pod will be reinstalled on space shuttle Atlantis. The orbital maneuvering system provided the shuttle with thrust for orbit insertion, rendezvous and deorbit, and could provide up to 1,000 pounds of propellant to the aft reaction control system. The OMS is housed in two independent pods located on each side of the shuttle's aft fuselage. Each pod contains one OMS engine and the hardware needed to pressurize, store and distribute the propellants to perform the velocity maneuvers. Atlantis’ OMS pods were removed and sent to White Sands Test Facility in New Mexico to be cleaned of residual toxic propellant. The work is part of the Space Shuttle Program’s transition and retirement processing of the shuttle fleet. A groundbreaking was held Jan. 18 for Atlantis' future home, a 65,000-square-foot exhibit hall in Shuttle Plaza at the Kennedy Space Center Visitor Complex.

Each year, the NESC produces the NESC Technical Update, which highlights two or three individuals from each Center and includes assessments throughout the year. Because of the critical contributions to the NESC mission this year, Rob Jankovsky, NESC Chief Engineer at GRC, chose two individuals to be highlighted. This year, it is Andrew Ring and Michael Cooper. The Lead Analyst for GRC’s Chemical and Thermal Propulsion Systems branch, Mr. Michael Cooper pictured here in this environmental portrait on August 16, 2024. He is supporting NESC test operations on reaction control system thrusters for Gateway’s Power & Propulsion Element. “These thrusters are small with few moving parts, but the heat and mass transfers involved are very complex,” he said. The test campaign is putting the thrusters through a rigorous profile to simulate the lifetime they will experience over decades in space. Mr. Cooper is analyzing test data gathered on chamber pressure, temperature, flow rates, and more to develop models on thruster performance. He also built the tool that read in that data from the test stand instrumentation. Photo Credit: (NASA/Sara Lowthian-Hanna)

The OMS provided the shuttle with thrust for orbit insertion, rendezvous and deorbit, and could provide up to 1,000 pounds of propellant to the aft reaction control system. The OMS is housed in two independent pods located on each side of the shuttle’s aft fuselage. Each pod contains one OMS engine and the hardware needed to pressurize, store and distribute the propellants to perform the velocity maneuvers. Atlantis’ OMS pods were removed and sent to the test facility at White Sands Space Harbor in New Mexico to be cleaned of residual toxic propellant. The work is part of the Space Shuttle Program’s transition and retirement processing of the space shuttle fleet. A groundbreaking was held Jan. 18 for Atlantis’ future home, a 65,000-square-foot exhibit hall in Shuttle Plaza at the Kennedy Space Center Visitor Complex. Atlantis is scheduled to roll over to the visitor complex in November in preparation for the exhibit’s grand opening in July 2013. For more information, visit http://www.nasa.gov/transition.

Each year, the NESC produces the NESC Technical Update, which highlights two or three individuals from each Center and includes assessments throughout the year. Because of the critical contributions to the NESC mission this year, Rob Jankovsky, NESC Chief Engineer at GRC, chose two individuals to be highlighted. This year, it is Andrew Ring and Michael Cooper. The Lead Analyst for GRC’s Chemical and Thermal Propulsion Systems branch, Mr. Michael Cooper, is supporting NESC test operations on reaction control system thrusters for Gateway’s Power & Propulsion Element. “These thrusters are small with few moving parts, but the heat and mass transfers involved are very complex,” he said. The test campaign is putting the thrusters through a rigorous profile to simulate the lifetime they will experience over decades in space. Mr. Cooper is analyzing test data gathered on chamber pressure, temperature, flow rates, and more to develop models on thruster performance. He also built the tool that read in that data from the test stand instrumentation. Photo Credit: (NASA/Sara Lowthian-Hanna)

NASA research pilot Jack McKay was injured in a crash landing of the X-15 #2 on November 9, 1962. Following the launch from the B-52 to begin flight 2-31-52, he started the X-15's rocket engine, only to discover that it produced just 30 percent of its maximum thrust. He had to make a high-speed emergency landing on Mud Lake, NV, without flaps but with a significant amount of fuel still in the aircraft. As the X-15 slid across the lakebed, the left skid collapsed; the aircraft turned sideways and flipped onto its back. McKay suffered back injuries but was eventually able to resume X-15 pilot duties, making 22 more flights. The X-15 was sent back to North American Aviation and rebuilt into the X-15A-2.

X-15A-2 with full scale ablative and external tanks installed parked in front of hangar. In June 1967, the X-15A-2 rocket-powered research aircraft received a full-scale ablative coating to protect the craft from the high temperatures associated with hypersonic flight (above Mach 5). This pink eraser-like substance, applied to the X-15A-2 aircraft (56-6671), was then covered with a white sealant coat before flight. This coating would help the #2 aircraft reach the record speed of 4,520 mph (Mach 6.7).
