Guayama, PR
Guayama (, ), officially the Autonomous Municipality of Guayama ( es, Municipio Autónomo de Guayama) is a city and municipality on the Caribbean coast of Puerto Rico. As of the 2020 U.S. Census, the city had a population of 36,614. It is the center of the Guayama metropolitan area with a population of 68,442 in 2020. Etymology and nicknames The original name of the city is San Antonio de Padua de Guayama, named after the saint Anthony of Padua; as with other settlement names in Puerto Rico, the name was eventually shortened to ''Guayama''. According to legend, ''Guayama'' comes from the name of a Taíno cacique (chief), who was leader of the tribes in the southeastern coast of Puerto Rico. The Taíno word ''Guayama'' (''wayama'') is said to mean "great place" or "big open space". Another legend tells that the name of the town comes from the name of a woman called Juana Guayama who is said to have been an early owner of the land around Guayama and granter of the land in modern- ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

List Of Puerto Ricans In The United States Space Program
This is a list of notable Puerto Rican scientists involved in the United States Space Program, also known as the National Aeronautics and Space Administration (NASA) and their contributions to said program. This list is not limited to Puerto Ricans born in Puerto Rico, it also includes people of Puerto Rican descent born elsewhere. According to an article written by Margarita Santori Lopez for the official newspaper of the University of Puerto Rico's Mayagüez Campus, "Prensa RUM", as of 2003, of the 114 Hispanics working at NASA Goddard Space Flight Center in Maryland, 70 were Puerto Ricans or of Puerto Rican descent. Puerto Ricans and people of Puerto Rican descent, both men and women, have reached top positions in NASA, serving in sensitive leadership positions. On May 6, 2004, Joseph M. Acaba became the first person of Puerto Rican heritage to be named as a NASA astronaut candidate, when he was selected as a member of NASA Astronaut Training Group 19. On an average, only the ...

La Borinqueña
"" (from the native name of Puerto Rico, ''Borinquen'' or ''Boriquen''), ) is the official anthem of Puerto Rico. After Puerto Rico became known as "The Commonwealth of Puerto Rico" in 1952, the first elected governor, Luis Muñoz Marín, signed law #2 of July 24, 1952, which made an altered version of the musical composition known as "La Borinqueña" its national anthem. The words that go with the composition were approved by governor Carlos Romero Barceló on July 27, 1977, as per law #123."La Fortaleza, Simbolos Patrios: Himno de Puerto Rico" .

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces.

E-mail
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simult ...

Mauna Loa
Mauna Loa ( or ; Hawaiian: ; en, Long Mountain) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean. The largest subaerial volcano (as opposed to subaqueous volcanoes) in both mass and volume, Mauna Loa has historically been considered the largest volcano on Earth, dwarfed only by Tamu Massif. It is an active shield volcano with relatively gentle slopes, with a volume estimated at , although its peak is about lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive. Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Acronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in ''Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in ''radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like ''NASA'' and ''UNESCO''; as individual letters, like ''FBI'', ''TNT'', and ''ATM''; or as both letters and words, like '' JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary and st ...

HI-SEAS
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) is an analog habitat for human spaceflight to Mars currently operated by the International MoonBase Alliance. HI-SEAS is located in an isolated position on the slopes of the Mauna Loa volcano on the island of Hawaii. The area has Mars-like features and an elevation of approximately above sea level. The first HI-SEAS study was in 2013 and NASA's Human Research Program continues to fund and sponsor follow-up studies. The missions are of extended duration from four months to a year. Its missions place HI-SEAS in the company of a small group of analogs that are capable of operating very long duration missions (8-months and longer) in isolated and confined environments, such as Mars500, Concordia, and the International Space Station. The purpose of the detailed research studies is to determine what is required to keep a space flight crew happy and healthy during an extended mission to Mars and while living on Mars. Rese ...
