STS-26 Orbiter processing facility

Wallops Flight Facility (WFF) (IATA: WAL, ICAO: KWAL, FAA LID: WAL), located on the Eastern Shore of the U.S. state of Virginia, is operated by NASA's Goddard Space Flight Center, primarily as a rocket launch site to support science and exploration missions for NASA and other U.S. government agencies. WFF includes an extensively instrumented range to support launches of more than a dozen types of sounding rockets, small expendable suborbital and orbital rockets, high altitude balloon flights carrying scientific instruments for atmospheric and astronomical research and—using its Research Airport—flight tests of aeronautical research aircraft including unmanned aerial vehicles.

This is an alternate version of the Astronaut Class of 1992 patch. This one celebrates the class nickname, "The Hogs."

Pilots: Scott Horowitz, Brent Jett, Kevin Kregel, Kent Rominger

Mission specialists: Daniel T. Barry, Charles Brady, Catherine Coleman, Michael Gernhardt, John Grunsfeld, Wendy Lawrence, Jerry Linenger, Richard Linnehan, Michael Lopez-Alegria, Scott Parazynski, Winston Scott, Steven Smith, Joseph Tanner, Andy Thomas, Mary Weber
International mission specialists: Marc Garneau (Canada), Chris Hadfield (Canada), Maurizio Cheli (Italy), Jean-François Clervoy (France), Koichi Wakata (Japan)

Beginning with this NASA Group, non-US astronauts representing their home country's space agencies were brought in and trained alongside their NASA counterparts as full-fledged mission specialists, eligible to be assigned to any shuttle mission.

An alternate, humorous version of this patch also exists.

Pilots: Kenneth Cockrell, Eileen Collins, William G. Gregory, James Halsell, Charles Precourt, Richard Searfoss, Terrence Wilcutt

Mission specialists: Daniel Bursch, Leroy Chiao, Michael R. Clifford, Bernard Harris, Susan Helms, Thomas David Jones, William McArthur, James Newman, Ellen Ochoa, Ronald Sega, Nancy Currie, Donald A. Thomas, Janice Voss, Carl E. Walz, Peter Wisoff, David Wolf

Collins would go on to be the first female shuttle pilot, the first female shuttle commander, and then commander of the second "Return to Flight" mission in 2005. The "Hairballs" nickname, according to Jones in his book "Sky Walking," came after the group, the 13th NASA astronaut class, put a black cat on its group patch.

This a black-backed version of the Class of 90 patch. A blue version also exists.

Very hard to find, nicely designed Saturn S-II team patches. 

On January 31, 1977, it was taken by road to Dryden Flight Research Center at Edwards Air Force Base, to begin operational testing.
While at NASA Dryden Enterprise was used by NASA for a variety of ground and flight tests intended to validate aspects of the shuttle program.[9] The initial nine-month testing period was referred to by the acronym ALT, for "Approach and Landing Test". These tests included a maiden "flight" on February 18, 1977, atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking characteristics of the mated system. Ground tests of all orbiter subsystems were carried out to verify functionality prior to atmospheric flight.
The mated Enterprise/SCA combination was then subjected to five test flights with Enterprise unmanned and unactivated. The purpose of these test flights was to measure the flight characteristics of the mated combination. These tests were followed with three test flights with Enterprise manned to test the shuttle flight control systems.

There are two versions be low, I suspect the top one is the original. They are very similar. The "G" in the top one has a descending vertical. 

3" patch, fabric back. Not sure what the "P.I." stands for, some indications are P. Island, a tracking station somewhere, but I am unable to secure that name.

This patch varies from the common version as it has a more fit, cut-edge. The common version features a marrowed edge.

This is a later production run of the official issue version. NASA did not approve of their use of the seriffed "NASA" font, so it was revised to a more Helvetica-like font. The rudders match the original version. 

This version retains the seriffed NASA font, but has different stiching in the rudder (two distinct rudders). 

Early production run version. Identifiable by the seriffed "NASA" and joined rudder stitching.

Seventeen men and women have been selected for the astronaut

The John F. Kennedy Space Center (KSC) is the United States launch site that has been used for every NASA human space flight since 1968. Although such flights are currently on hiatus, KSC continues to manage and operate unmanned rocket launch facilities for the U.S. government's civilian space program from three pads at the adjoining Cape Canaveral Air Force Station. Its Vehicle Assembly Building (VAB) is the fourth-largest structure in the world by volume and was the largest when completed in 1965.

The Station Operations Support Officer is the console operator that is charged with those logistics support funtions that address on-orbit maintenance, support data and documentation, logistics information systems, maintenance data collection and maintenance analysis.

The Space Flight Awareness (SFA) Program
a NASA-managed motivational and recognition program with invited representation from NASA and contractors having major responsibilities for human spaceflight mission success.

The Space Life Sciences Directorate manages a broad range of applied and basic scientific research, related ground and flight experiments and investigations, and flight crew interfacing hardware and systems including the planning and implementation of programs/projects in human life sciences, human life sciences flight experiments, medical operations and health care, lunar and planetary geology, Earth sciences, space science, and spacecraft and systems design relating to flight crew habitability and productivity.

The Lyndon B. Johnson Space Center (JSC) is the National Aeronautics and Space Administration's center for human spaceflight training, research, and flight control. The center consists of a complex of one hundred buildings constructed on 1,620 acres (656 ha) in Houston, Texas. Johnson Space Center is home to the United States astronaut corps and is responsible for training astronauts from both the U.S. and its international partners. It is often popularly referred to by its central function during missions, Mission Control

In the quest for high performance, reliability, and quality control, incentive contracts constituted only one of a number of blandishments. Several techniques were employed by MSFC, including cash awards and special recognition for quality control, cost reduction, and other activities. At MSFC, the Saturn V Program Office cooperated with the Manned Flight Awareness Office in a program to inform and remind all workers in the Apollo-Saturn program about the importance of their work and the need for individual efforts. By means of awards and recognition programs, the Manned Flight Awareness concept became an effective incentive technique. The prime contractors also conducted special incentive programs, in collaboration with the project managers and RMO personnel. North American's program was known as PRIDE (Personal Responsibility in Daily Effort), and Douglas had its "V.I.P." campaign (Value in Performance). MSFC's Manned Flight Awareness personnel and the contractors also participated in a program to make sure that vendors and subcontractors shipped critical spare hardware in special containers and boxes. These boxes were marked with stickers and placards imprinted with reminders to handle with particular care, because the hardware was important to the astronauts whose lives depended on the integrity of the hardware.

NASA has flown zero gravity flights on various aircraft for many years. In 1959, Project Mercury astronauts trained in a C-131 Samaritan aircraft, which was dubbed the "Vomit Comet".
Twin KC-135 Stratotankers were used until December 2004 but have since been retired. One, a KC-135A known as NASA 930, was also used by Universal Pictures and Imagine Entertainment for filming scenes involving weightlessness in the movie Apollo 13; that aircraft was retired in 2000 and is now on display at Ellington Field, near the Johnson Space Center. The KC-135A is estimated to have flown over 58,000 parabolas. The other (N931NA or NASA 931) made its final flight on October 29, 2004, and is permanently stored in the Pima Air & Space Museum in Tucson, Arizona.

Bermuda has been a long-time partner of NASA in supporting space exploration. The British territory hosted a radar tracking station from the Mercury Project in the early 1960s through most of the Space Shuttle Program. Recently re-opened with a temporary tracking station in 2012.

NASA Glenn Research Center’s Telescience Support Center (TSC) allows researchers on Earth to operate experiments onboard the International Space Station (ISS) and the space shuttles. NASA’s continuing investment in the required software, systems, and networks provides distributed ISS ground operations that enable payload developers and scientists to monitor and control their experiments from the Glenn TSC. The quality of scientific and engineering data is enhanced while the long-term operational costs of experiments are reduced because principal investigators and engineering teams can operate their payloads from their home institutions.
