STS-51-F was the 19th flight of NASA's Space Shuttle program and the eighth flight of Space Shuttle Challenger. It launched from Kennedy Space Center, Florida, on July 29, 1985, and landed eight days later on August 6, 1985.
A kilt is a garment resembling a wrap-around knee-length skirt, made of twill-woven worsted wool with heavy pleats at the sides and back and traditionally a tartan pattern. Originating in the Scottish Highland dress for men, it is first recorded in 16th century as the great kilt, a full-length garment whose upper half could be worn as a cloak. The small kilt or modern kilt emerged in the 18th century, and is essentially the bottom half of the great kilt. Since the 19th century, it has become associated with the wider culture of Scotland, and more broadly with Gaelic or Celtic heritage.

A thermographic camera is a device that creates an image using infrared (IR) radiation, similar to a normal camera that forms an image using visible light. Instead of the 400–700 nanometre (nm) range of the visible light camera, infrared cameras are sensitive to wavelengths from about 1,000 nm to about 14,000 nm (14 μm). The practice of capturing and analyzing the data they provide is called thermography.
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, thermography is particularly useful to the military and other users of surveillance cameras.
Classical test theory (CTT) is a body of related psychometric theory that predicts outcomes of psychological testing such as the difficulty of items or the ability of test-takers. It is a theory of testing based on the idea that a person's observed or obtained score on a test is the sum of a true score (error-free score) and an error score. Generally speaking, the aim of classical test theory is to understand and improve the reliability of psychological tests.
In psychometrics, item response theory (IRT) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables. It is a theory of testing based on the relationship between individuals' performances on a test item and the test takers' levels of performance on an overall measure of the ability that item was designed to measure. Several different statistical models are used to represent both item and test taker characteristics. Unlike simpler alternatives for creating scales and evaluating questionnaire responses, it does not assume that each item is equally difficult. This distinguishes IRT from, for instance, Likert scaling, in which "All items are assumed to be replications of each other or in other words items are considered to be parallel instruments". By contrast, item response theory treats the difficulty of each item as information to be incorporated in scaling items.

An incident is an event that could lead to loss of, or disruption to, an organization's operations, services or functions. Incident management (IcM) is a term describing the activities of an organization to identify, analyze, and correct hazards to prevent a future re-occurrence. These incidents within a structured organization are normally dealt with by either an incident response team (IRT), an incident management team (IMT), or Incident Command System (ICS). Without effective incident management, an incident can disrupt business operations, information security, IT systems, employees, customers, or other vital business functions.
Tartan is a pattern on clothing, usually associated with Scotland.
The Space Flyer Unit was a spacecraft which was launched by Japan on March 18, 1995.

Psychometric software is software that is used for psychometric analysis of data from tests, questionnaires, or inventories reflecting latent psychoeducational variables. While some psychometric analyses can be performed with standard statistical software like SPSS, most analyses require specialized tools.
The Scottish Register of Tartans (SRT) is Scotland's official non-ministerial department for the recording and registration of tartan designs, operating since 5 February 2009. As a governmental body, SRT is headquartered at HM General Register House in Edinburgh and is a division of the National Records of Scotland (NRS), formerly of the National Archives of Scotland (NAS) before its merger into NRS. SRT is the centralised agency for the recording of known historical tartans and for paid registration of new tartan designs, which must fulfill fairly stringent criteria. SRT subsumed this registration role from a variety of previous not-for-profit and commercial organisations, most now defunct. Since December 2018, the Keeper of the Scottish Register of Tartans is the head of the NRS. SRT's tartan database itself is also named the Scottish Register of Tartans. It is uncertain how large the database is, but it has absorbed records of at least 7,000 tartans from previous registries, in addition to accepting new entries from 2009 onward.
ASTM Subcommittee E20.02 on Radiation Thermometry is a subcommittee of the ASTM Committee E20 on Temperature Measurement, a committee of ASTM International. The subcommittee is responsible for standards relating to radiation or infrared (IR) temperature measurement. E20.02's standards are published along with the rest of the E20's standards in the Annual Book of ASTM Standards, Volume 14.03.
The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring. JPSS will aid in fulfilling the mission of the U.S. National Oceanic and Atmospheric Administration (NOAA), an agency of the Department of Commerce. Data and imagery obtained from the JPSS will increase timeliness and accuracy of public warnings and forecasts of climate and weather events, thus reducing the potential loss of human life and property and advancing the national economy. The JPSS is developed by the National Aeronautics and Space Administration (NASA) for the National Oceanic and Atmospheric Administration (NOAA), who is responsible for operation of JPSS. Three to five satellites are planned for the JPSS constellation of satellites. JPSS satellites will be flown, and the scientific data from JPSS will be processed, by the JPSS – Common Ground System (JPSS-CGS).
Criminal Minds: Beyond Borders is an American police procedural television series created by Erica Messer that aired on CBS from March 16, 2016, to May 17, 2017. The show is produced by The Mark Gordon Company in association with CBS Television Studios and ABC Studios. The production is a spin-off from original series, Criminal Minds, airing on the same network, and is the third series in the Criminal Minds franchise. Criminal Minds: Beyond Borders follows an elite team of FBI agents of the fictional International Response Team (IRT) tasked with solving cases that involve American citizens on international soil.
