KENNEDY SPACE CENTER, FLA. -- The locomotive and rail cars carrying solid rocket booster motor segments and two aft exit cone segments roll past the Vehicle Assembly Building to the Rotation, Processing and Surge Facility (RPSF) in Kennedy Space Center's Launch Complex 39 Area. The RPSF is used for solid rocket motor receiving, rotation and inspection, and supports aft booster buildup. When live solid rocket motor segments arrive at the processing facility, they are positioned under one of the cranes. Handling slings are then attached to and remove the railcar cover. The segment is inspected while it remains horizontal. The two overhead cranes hoist the segment, rotate it to a vertical position and place it on a fixed stand. The aft handling ring is then removed. The segment is hoisted again and lowered onto a transportation and storage pallet, and the forward handling ring is removed to allow inspections. It is then transported to one of the surge buildings and temporarily stored until it is needed for booster stacking in the VAB. While enroute, solid rocket motor segments were involved in a derailment in Alabama. The rail cars carrying these segments remained upright and were undamaged. An inspection determined these segment cars could continue on to Florida. The segments themselves will undergo further evaluation at Kennedy before they are cleared for flight. Other segments involved in the derailment will be returned to a plant in Utah for further evaluation. Photo credit: NASA/George Shelton

Teams from NASA and Northrop Grumman fire a ground-based version of a booster for the agency’s SLS (Space Launch System) rocket June 26. Secured horizontally in a test stand at Northrop Grumman’s test facility in Promontory, Utah, the single five-segment booster motor fired for more than two minutes and produced 3.9 million pounds of thrust. The booster for this test, known as Demonstration Motor-1 (DM-1), is the result of the Booster Obsolescence Life Extension (BOLE) project. This test was the first full-scale ground test of a new five-segment solid rocket motor.

The booster for this test, known as Demonstration Motor-1 (DM-1), is the result of the Booster Obsolescence Life Extension (BOLE) project. This test was the first full-scale ground test of a new five-segment solid rocket motor. During the test, there was an abnormal event approximately 15 seconds before the end of the motor firing. Despite this event, NASA achieved several of the test’s primary objectives and received valuable data on technical risks identified ahead of the test. Testing this evolved booster for the SLS will help evaluate improvements and new materials in the boosters. The BOLE effort was launched to transition to a more efficient, lower cost commercial solution for the boosters for the SLS rocket. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

Teams from NASA and Northrop Grumman fire a ground-based version of a booster for the agency’s SLS (Space Launch System) rocket June 26. Secured horizontally in a test stand at Northrop Grumman’s test facility in Promontory, Utah, the single five-segment booster motor fired for more than two minutes and produced 3.9 million pounds of thrust. The booster for this test, known as Demonstration Motor-1 (DM-1), is the result of the Booster Obsolescence Life Extension (BOLE) project. This test was the first full-scale ground test of a new five-segment solid rocket motor. During the test, there was an abnormal event approximately 15 seconds before the end of the motor firing. Despite this event, NASA achieved several of the test’s primary objectives and received valuable data on technical risks identified ahead of the test. Testing this evolved booster for the SLS will help evaluate improvements and new materials in the boosters. The BOLE effort was launched to transition to a more efficient, lower cost commercial solution for the boosters for the SLS rocket. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all. For more information, contact NASA Marshall’s Office of Communications at 256-544-0034.

Inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida, Pablo Martinez, a handling, mechanical and structures engineer on the Jacobs Technology Inc. Test and Operations Support Contract, prepares to insert the first of many pins that will secure the Space Launch System’s (SLS) right-hand motor segment to the rocket’s right-hand aft skirt. The right-hand motor segment is one of five segments that makes up one of two solid rocket boosters. Once the aft segments are mated to the two aft skirts, they will be moved to the Vehicle Assembly Building for stacking on the mobile launcher. Manufactured by Northrop Grumman in Utah, the twin boosters provide more than 75 percent of the total SLS thrust at launch. Under the Artemis program, NASA will land the first woman and the next man on the Moon by 2024. The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and SLS as an integrated system ahead of crewed flights to the Moon.

CAPE CANAVERAL, Fla. – In the Assembly and Refurbishment Facility at NASA's Kennedy Space Center, a crane is lowered over the aft skirt for the Ares 1-X rocket. The segment is being lifted into a machine shop work stand for drilling modifications. The modifications will prepare it for the installation of the auxiliary power unit controller, the reduced-rate gyro unit, the booster decelerator motors and the booster tumble motors. Ares I is an in-line, two-stage rocket that will transport the Orion crew exploration vehicle to low-Earth orbit. Ares I-X is a test rocket. The Ares I first stage will be a five-segment solid rocket booster based on the four-segment design used for the shuttle. Ares I’s fifth booster segment allows the launch vehicle to lift more weight and reach a higher altitude before the first stage separates from the upper stage, which ignites in midflight to propel the Orion spacecraft to Earth orbit.

CAPE CANAVERAL, Fla. – – The NASA Railroad (right) is ready for the exchange of the Florida East Coast Railway cars carrying the booster segments for the Ares I-X test rocket. The four reusable motor segments and the nozzle exit cone, manufactured by the Ares I first-stage prime contractor Alliant Techsystems Inc., or ATK, departed Utah March 12 on the seven-day, cross-country trip to Florida. The segments will be delivered to the Rotation, Processing and Surge Facility for final processing and integration. The booster used for the Ares I-X launch is being modified by adding new forward structures and a fifth segment simulator.

CAPE CANAVERAL, Fla. -- In Hangar AF at Cape Canaveral, Fla., separation rings are moved above two segments of one of the retrieved solid rocket boosters from the STS-126 launch. The rings will be lowered and locked around the segments. The pins attaching the segments to each other are removed at the start. Each separation ring has three joints that help mold the ring around the segment and an air motor is used to rotate the rings to separate the segments. After disassembly, the segments will be sent to ATK (Alliant Techsystems) in Utah for final processing and return to Kennedy for another shuttle launch. Photo credit: NASA/Jack Pfaller
