CAPE CANAVERAL, Fla. – Cranes remove a full-size, 149-foot-long, space shuttle solid rocket booster, or SRB, replica from the Kennedy Space Center Visitor Complex as the space-themed attraction makes way for a new exhibit featuring space shuttle Atlantis, which is currently undergoing preparations to go on public display. The SRB is being placed into temporary storage at NASA's Kennedy Space Center. The SRB was part of a mockup of the external tank and two SRBs at the visitor complex that were used to show visitors the size of actual space shuttle components. A space shuttle rode piggyback on the tank and boosters at liftoff and during the ascent into space. The SRBs burned out after about two-and-a-half minutes of flight. After recovery from the ocean, the boosters could be used repeatedly. Photo credit: NASA/Jim Grossman

The towing ship, Liberty, towed a recovered solid rocket booster (SRB) for the STS-5 mission to Port Canaveral, Florida. The recovered SRB would be inspected and refurbished for reuse. The Shuttle's SRB's and solid rocket motors (SRM's) are the largest ever built and the first designed for refurbishment and reuse. Standing nearly 150-feet high, the twin boosters provide the majority of thrust for the first two minutes of flight, about 5.8 million pounds. The requirement for reusability dictated durable materials and construction to preclude corrosion of the hardware exposed to the harsh seawater environment. The SRB contains a complete recovery subsystem that includes parachutes, beacons, lights, and tow fixture.

This photograph shows the left side of the solid rocket booster (SRB) segment as it awaits being mated to the nose cone and forward skirt in the Dynamic Test Stand at the east test area of the Marshall Space Flight Center (MSFC). The SRB would be attached to the external tank (ET) and then the orbiter later for the Mated Vertical Ground Vibration Test (MVGVT), that resumed in October 1978. The stacking of a complete Shuttle in the Dynamic Test Stand allowed test engineers to perform ground vibration testing on the Shuttle in its liftoff configuration. The purpose of the MVGVT was to verify that the Space Shuttle would perform as predicted during launch. The platforms inside the Dynamic Test Stand were modified to accommodate two SRB's to which the ET was attached.

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. View provided by KSC with alternate number KSC-88PC-1323.

The structural test article to be used in the solid rocket booster (SRB) structural and load verification tests is being assembled in a high bay building of the Marshall Space Flight Center (MSFC). The Shuttle's two SRB's are the largest solids ever built and the first designed for refurbishment and reuse. Standing nearly 150-feet high, the twin boosters provide the majority of thrust for the first two minutes of flight, about 5.8 million pounds, augmenting the Shuttle's main propulsion system during liftoff. The major design drivers for the solid rocket motors (SRM's) were high thrust and reuse. The desired thrust was achieved by using state-of-the-art solid propellant and by using a long cylindrical motor with a specific core design that allows the propellant to burn in a carefully controlled marner. At burnout, the boosters separate from the external tank and drop by parachute to the ocean for recovery and subsequent refurbishment.

CAPE CANAVERAL, Fla. – The solid rocket booster SRB retrieval ships, Liberty Star and Freedom Star, are docked in the Banana River at Cape Canaveral Air Force Station's Hangar A F. The NASA vessels were used during the space shuttle era to retrieve the SRBs following shuttle launches. Kennedy is located on Merritt Island, a barrier island, about 34 miles long and varying in width from five to 10 miles. Only 6,000 acres are actually used for operational activities. The Kennedy Space Center is also a National Wildlife Refuge. Consisting of 140,000 acres, the refuge provides a wide variety of habitats: coastal dunes, saltwater estuaries and marshes, freshwater impoundments, scrub, pine flatwoods and hardwood hammocks providing habitat for more than 1,500 species of plants and animals.

KENNEDY SPACE CENTER, FLA. - In the Assembly and Refurbishment Facility at NASA's Kennedy Space Center, the solid rocket booster aft skirt designated for use on the first stage of the ARES I-1 launch vehicle is being prepared for its first test flight. Ares I is the vehicle being developed for launch of the crew exploration vehicle (CEV), named Orion. Ares I-1 is currently targeted for launch from Launch Pad 39B in 2009 using the SRB first stage and a simulated second stage and simulated CEV. Ares I ascent tests and Ares I orbital tests will also take place at Kennedy at later dates. Photo credit: NASA/Jack Pfaller

KENNEDY SPACE CENTER, FLA. - During solid rocket booster lifting operations on Launch Pad 17-B at Cape Canaveral Air Force Station in Florida, a moth is spotted resting on a structure, oblivious to the action around it. The SRB will be mated with the Boeing Delta II rocket already in place. The Delta rocket is the launch vehicle for NASA's Solar Terrestrial Relations Observatory (STEREO). Preparations are under way for a liftoff no earlier than Aug. 1. STEREO consists of two spacecraft whose mission is the first to take measurements of the sun and solar wind in 3-D. This new view will improve our understanding of space weather and its impact on the Earth. Photo credit: NASA/Kim Shiflett
