KENNEDY SPACE CENTER, FLA. - The Freedom Star is berthed at the Turn Basin near the Vehicle Assembly Building. The ship has recently returned to KSC after refurbishment at Fort George Island, Fla., including new paint. Freedom Star is one of the solid rocket booster (SRB) retrieval ships built to recover the SRB casings released over the Atlantic Ocean after launch of a Space Shuttle. In addition to the SRBs, the ship recovers the drogue and main parachutes that slow the boosters’ speed before splashdown. Some of the retrieval equipment can be seen on the rear deck. The ships also tow the external tanks built at the Michoud Space Systems Assembly Facility near New Orleans to Port Canaveral, Fla. Freedom Star was brought to KSC today for a visit by NATO Parliamentarians.

KENNEDY SPACE CENTER, FLA. - The media tour the Solid Rocket Booster (SRB) Assembly and Refurbishment Facility where SRB segments are refurbished. In the background can be seen the frustum and nose cap of an SRB. The media event featured the movement of the first SRB segments to the Vehicle Assembly Building for stacking for Return to Flight mission STS-114. Two SRBs support the liftoff of the Space Shuttle on a launch. The twin 149-foot tall, 12-foot diameter SRBs provide the main propulsion system during launch to place the orbiters in the proper orbit around the Earth. They operate parallel with the Space Shuttle main engines for the first two minutes of flight and jettison away from the orbiter, with help from the Booster Separation Motors, about 26.3 nautical miles above the Earth’s surface.

STS-29 Discovery, Orbiter Vehicle (OV) 103, solid rocket booster (SRB) right aft segment is being prepared for stacking in the Kennedy Space Center (KSC) Vehicle Assembly Building (VAB). Technicians examine and work with SRB seal from scaffolding platform. The twin sets of boosters provide 80 percent of the space shuttle launch thrust. Each SRB is made up of four "loaded" or fueled segments. The SRBs operate in parallel with the space shuttle main engines (SSMEs) for the first two minutes of flight providing additional thrust needed to escape the gravitational pull of the Earth. At an altitude of approximately 24 nautical miles, the SRBs separate, descend on parachutes, and land in the Atlantic Ocean where they are recovered and reused on future flights.

The forward section of each booster, from nose cap to forward skirt contains avionics, a sequencer, forward separation motors, a nose cone separation system, drogue and main parachutes, a recovery beacon, a recovery light, a parachute camera on selected flights and a range safety system. Each SRB weighs approximately 1.3 million pounds at launch.

KENNEDY SPACE CENTER, FLA. - In the Vehicle Assembly Building (VAB), a segment of a Solid Rocket Booster (SRB) is lifted to the 16th level. This right aft center segment will be stacked with the aft booster that arrived in the VAB Nov. 22 for the Return to Flight mission STS-114. Two SRBs are stacked on the Mobile Launch Platform and later joined by the External Tank. The twin 149-foot tall, 12-foot diameter SRBs provide the main propulsion system during launch. They operate parallel with the Space Shuttle main engines for the first two minutes of flight and jettison away from the orbiter with help from the Booster Separation Motors, about 26.3 nautical miles above the Earth’s surface.

KENNEDY SPACE CENTER, FLA. - - In the SRB Assembly and Refurbishment Facility, some of the STS-114 crew listen to Greg Henry, SRB Element director of Manufacturing Operations with United Space Alliance. Crew members, from center to right, are Pilot James Kelly and Mission Specialists Soichi Noguchi and Andrew Thomas. Noguchi represents the Japanese Aerospace and Exploration Agency. In the background, at right, is Tom Engler, Marshall Space Flight Center SRB Resident Office lead. The crew is at KSC for familiarization with Shuttle and mission equipment.

KENNEDY SPACE CENTER, FLA. -- In high bay 1 of the Vehicle Assembly Building at NASA's Kennedy Space Center, the suspended external tank is lowered between the solid rocket boosters, or SRBs, installed on the mobile launcher platform. The tank will be mated with the boosters for launch. Work to remove and replace the feed-through connector on the external tank will be done in parallel with integrated ET/SRB testing in preparation for space shuttle Endeavour to join the stack later in January. The STS-123 mission is targeted for launch on Endeavour in mid-March. The 25th assembly flight to the International Space Station, Endeavour's payload includes the Japanese Experiment Logistics Module Pressurized Section. Photo credit: NASA/Kim Shiflett

KENNEDY SPACE CENTER, FLA. - David Martin, NASA SRB project manager, congratulates employees in the Assembly and Refurbishment Facility for preparing the first (left) solid rocket booster aft skirt for mission STS-114 on schedule. The segment, seen behind Martin, will be transferred to the Rotation Processing and Surge Facility (RPSF) for stacking. At the RPSF an aft motor segment and an external tank attach ring will be installed. The stack will then be moved to the Vehicle Assembly Building for further build-up. This is the first transfer of a large piece of hardware from SRB to Ground Operations. It is a significant milestone in the march to Return to Flight.

KENNEDY SPACE CENTER, FLA. -- In the Vehicle Assembly Building, near the top of the solid rocket booster, Henry Jones and Richard Bruns begin to detach the SRB system tunnel cover on the 36 cables inside. Jones and Bruns are United Space Alliance SRB technicians. The SRB is part of Space Shuttle Atlantis, rolled back from Launch Pad 39A in order to conduct tests on the cables. A prior extensive evaluation of NASA’s SRB cable inventory on the shelf revealed conductor damage in four (of about 200) cables. Shuttle managers decided to prove the integrity of the system tunnel cables already on Atlantis before launching. Workers are conducting inspections, making continuity checks and conducting X-ray analysis on the cables. The launch has been rescheduled no earlier than Feb. 6.<br

KENNEDY SPACE CENTER, FLA. - In a Vehicle Assembly Building (VAB) high bay, workers check the alignment of a Solid Rocket Booster (SRB) aft center segment as it is lowered toward an aft segment already secured to a Mobile Launch Platform. These segments are part of the right SRB for the Space Shuttle Return to Flight mission, STS-114. Two SRBs are stacked on a Mobile Launch Platform for each Shuttle flight and later joined by an External Tank. The twin 149-foot tall, 12-foot diameter SRBs provide the main propulsion system during launch. They operate in parallel with the Space Shuttle main engines for the first two minutes of flight and jettison away from the orbiter with help from the Booster Separation Motors, about 26.3 nautical miles above the Earth’s surface.

KENNEDY SPACE CENTER, FLA. - The media visit the operations center on board the Freedom Star, one of the Solid Rocket Booster (SRB) retrieval ships. The stop was part of a day-long event that featured the movement of the first SRB segments to the Vehicle Assembly Building for stacking for Return to Flight mission STS-114. Two SRBs support the liftoff of the Space Shuttle on a launch. The twin 149-foot tall, 12-foot diameter SRBs provide the main propulsion system during launch to place the orbiters in the proper orbit around the Earth. They operate parallel with the Space Shuttle main engines for the first two minutes of flight and jettison away from the orbiter, with help from the Booster Separation Motors, about 26.3 nautical miles above the Earth’s surface.
