NASA Coqui
The Coquí and Coquí 2 (Coquí Dos) campaign involved a sequence of sounding rocket launches in order to study the dynamics of the E- and F-region ionosphere and increase our understanding of layering phenomena, such as sporadic E layers. The studies were supported by the United States' National Aeronautics and Space Administration (NASA) and carried out in 1992 and 1998 respectively.https://www.nasa.gov/centers/goddard/pdf/106040main_coquidos.pdf NASA launched sounding rockets from the Puerto Rican coastal town of Vega Baja, about 20 miles west of San Juan. Among the stated goals were to study how the Earth's ionosphere reacts to naturally occurring phenomena by artificially simulating these phenomena using a high-frequency (HF) radar and study the ionospheric response with both the Arecibo Observatory The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Ba ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Ionosphere
The ionosphere () is the ionized part of the upper atmosphere of Earth, from about to above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth. History of discovery As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field. Sixty years later, Guglielmo Marconi received the first trans-Atlantic radio signal on December 12, 1901, in St. John's, Newfoundland (now in Canada) using a kite-supported antenna for reception. The transmitting station in Poldhu, Cornwall, used a spark-gap transmitter to produce a signal with a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Aeronautics And Space Administration
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown manageme ...

Arecibo Observatory
The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Barrio Esperanza, Arecibo, Puerto Rico owned by the US National Science Foundation (NSF). The observatory's main instrument was the Arecibo Telescope, a spherical reflector dish built into a natural sinkhole, with a cable-mount steerable receiver and several radar transmitters for emitting signals mounted above the dish. Completed in 1963, it was the world's largest single-aperture telescope for 53 years, surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China. Following two breaks in cables supporting the receiver platform in mid-2020, the NSF decommissioned the telescope. A partial collapse of the telescope occurred on December 1, 2020, before controlled demolition could be conducted. In 2022, the NSF announced the telescope will not be rebuilt, with an education ...

Coquí
Coquí is the common name for several species of small frogs in the genus ''Eleutherodactylus'' native to Puerto Rico. They are onomatopoeically named for the very loud mating call which the males of two species, the common coqui and the upland coqui, make at night. The coquí is one of the most common frogs in Puerto Rico, with more than 16 different species found within its territory, including 13 in El Yunque National Forest. Other species of this genus can be found in the rest of the Caribbean and elsewhere in the Neotropics, in Central and South America. The coquí is an unofficial national symbol of Puerto Rico; there is a Puerto Rican expression that goes, “Soy de aquí, como el coquí”, which translates to “I’m from here, like the coquí." Characteristics ''Eleutherodactylus'' is a small tree frog that can vary in color. These frogs can be a mixture of brown, yellow, green, and gray on the top and the bottom side of their body is either white or yellow. The ...

NASA Programs
This is a list of NASA missions, both crewed and robotic, since the establishment of NASA in 1958. There are over 80 currently active science missions. X-Plane program Since 1945, NACA (NASA's predecessor) and, since 1958, NASA have conducted the X-Plane Program. The program was originally intended to create a family of experimental aircraft not intended for production beyond the limited number of each design built solely for flight research. The first X-Plane, the Bell X-1, was the first rocket-powered airplane to break the sound barrier on October 14, 1947. X-Planes have set numerous milestones since then, both crewed and unpiloted. Human spaceflight NASA has successfully launched 166 crewed flights. Three have ended in failure, causing the deaths of seventeen crewmembers in total: Apollo 1 (which never launched) killed three crew members in 1967, STS-51-L ( the ''Challenger'' disaster) killed seven in 1986, and STS-107 ( the ''Columbia'' disaster) killed seven m ...
