Kwajalein Island
Kwajalein Atoll (; Marshallese: ) is part of the Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents (about 1,000 mostly U.S. civilian personnel) often use the shortened name, Kwaj . The total land area of the atoll amounts to just over . It lies in the Ralik Chain, southwest of Honolulu, Hawaii. The US Navy has hosted a naval base on Kwajalein Island since World War II. It was the final resting place of the German cruiser '' Prinz Eugen'' after it survived the Operation Crossroads nuclear test in 1946. In the late 1950s, the US Army took over the base as part of their Nike Zeus anti-ballistic missile efforts, and since then the atoll has been widely used for missile tests of all sorts. Today it is part of the Ronald Reagan Ballistic Missile Defense Test Site, with various radars, tracking cameras, missile launchers, and many support systems spread across many isl ...

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way" making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, ''calx'', and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway utilised earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by enslaved bodies or flocks of sheep. Today, this work is done by machines. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.

Ebeye
Ebeye ( ; Marshallese: , or in older orthography, ; locally, , , after the English pronunciation) is the most populous island of Kwajalein Atoll in the Marshall Islands, as well as the center for Marshallese culture in the Ralik Chain of the archipelago. Settled on of land, it has a population of more than 15,000. Over 50% of the population is estimated to be under the age of 18. History Etymology When Christian missionaries first arrived in the Marshall Islands, they introduced Latin script writing and orthographized the Marshallese language. Originally, Ebeye was written ''Ebeje'' by Europeans (' in modern orthography, pronounced ), which (according to elders of the atoll) means "making something out of nothing." However, the colonial German administration mispronounced the J as if it were German language , and foreign observers recorded the resulting pronunciation as ''Ebeye''.

Roi-Namur
Roi-Namur ( ) is an island in the north part of the Kwajalein Atoll in the Marshall Islands. Today it is a major part of the Ronald Reagan Ballistic Missile Defense Test Site, hosting several radar systems used for tracking and characterizing missile reentry vehicles (RV) and their penetration aids (penaids). Etymology The name of the new island is after the formerly separate islands Roi and Namur were joined by landfill. ''Roi'' is originally from Marshallese ''Ruot'', while ''Namur'' is originally from Marshallese ''Nim̧ur''. History Germany annexed the Marshalls in 1885 but did not put government officials on the islands until 1906, leaving island affairs to a group of powerful German trading companies. Under the Treaty of Versailles, Japan took over after World War I. They colonised the Marshalls extensively, developing and fortifying large bases on many of the islands. Roi-Namur was the target of the U.S. 4th Marine Division in the Battle of Kwajalein, in February 1944. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
