STS-42
STS-42 was a NASA Space Shuttle Space Shuttle Discovery, ''Discovery'' mission with the Spacelab module. Liftoff was originally scheduled for 8:45 Eastern Time Zone, EST (13:45 Coordinated Universal Time, UTC) on January 22, 1992, but the launch was delayed due to weather constraints. ''Discovery'' successfully lifted off an hour later at 9:52:33 EST (14:52:33 UTC) on her 14th flight. The main goal of the mission was to study the effects of weightlessness, microgravity on a variety of organisms. The shuttle landed at 8:07:17 Pacific Time Zone, PST (16:07:17 UTC) on January 30, 1992, on Runway 22, Edwards Air Force Base, California. STS-42 was the first of two flights in 1992 of ''Discovery'', the second of which occurred during STS-53, which launched on December 2, 1992. The mission was also the last mission of the Space Shuttle ''Discovery'' to have a seven-member crew until STS-82, which was launched on February 11, 1997.

Public Health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The ''public'' can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of ''health'' takes into account physical, psychological, and Well-being, social well-being, among other factors.What is the WHO definition of health? from the Preamble to the Constitution of WHO as adopted by the Internationa ...

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, Electromagnetism, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control ...

Summa Cum Laude
Latin honors are a system of Latin phrases used in some colleges and universities to indicate the level of distinction with which an academic degree has been earned. The system is primarily used in the United States. It is also used in some Southeastern Asian countries with European colonial history, such as Indonesia and the Philippines, and African countries such as Zambia and South Africa, although sometimes translations of these phrases are used instead of the Latin originals. The honors distinction should not be confused with the honors degree, honors degrees offered in some countries, or with honorary degree, honorary degrees. The system usually has three levels of honor (listed in order of increasing merit): ''cum laude'', ''magna cum laude'', and ''summa cum laude''. Generally, a college or university's regulations set out definite criteria a student must meet to obtain a given honor. For example, the student might be required to achieve a specific grade point average, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a List of human spaceflight programs, human spaceflight program to serve as a commander or crew member of a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and space tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek ). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Standard Chinese, Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear.

Sts-42-patch
STS-4 was the fourth NASA Space Shuttle mission, and also the fourth for Space Shuttle ''Columbia''. Crewed by Ken Mattingly and Henry Hartsfield, the mission launched on June 27, 1982, and landed a week later on July 4, 1982. Due to parachute malfunctions, the SRBs were not recovered. STS-4 was the final test flight for the Space Shuttle; it was thereafter officially declared to be operational. ''Columbia'' carried numerous scientific payloads during the mission, as well as military missile detection systems. Crew STS-4, being the last test flight of the Space Shuttle, was also the last to carry a crew of two astronauts. Commander Ken Mattingly had previously flown as Command Module Pilot on Apollo 16, and was also the original Command Module Pilot for Apollo 13 before being replaced by his backup, Jack Swigert, after being exposed to German measles. Hartsfield was a rookie astronaut who had transferred to NASA in 1969 after the cancellation of the Air Force's Manned O ...
