Mount Lemmon
Mount Lemmon, with a summit elevation of , is the highest point in the Santa Catalina Mountains. It is located in the Coronado National Forest north of Tucson, Arizona, United States. Mount Lemmon was named for botanist Sara Plummer Lemmon, who trekked to the top of the mountain with her husband and E. O. Stratton, a local rancher, by horse and foot in 1881. Mount Lemmon is also known as Babad Do'ag, or Frog Mountain to the Tohono O'odham. Geography Climate Due to the elevation change from the bottom to the top, the summit of the mountain can be twenty to thirty degrees cooler than the base. It usually sees at least one snow fall during the winter months, making it a cool escape and popular tourist attraction for Tucson inhabitants. Geology Mount Lemmon is made up of Bolsa Quartzite, Dripping Spring Quartzite, and a local sandstone and conglomerate. The portions have been intruded by a Diabase Dike of the Apace Group.

Apache Group (geology)
The Apache Group is a Mesoproterozoic group of geologic formations in the southwestern United States. The Apache Group—or some underlying Vishnu Basement Rocks (Ruin Granite)—are prominently found in all of the Sierra Ancha range, the range being separated by faults from its neighboring Mazatzal Mountains west, and the Salt River to the south. The Apache Group extends to regions east of the Sierra Ancha, and also regionally to Globe just south-southeast, and the neighboring Dripping Spring Mountains, again just south of the Globe region. The Apache Group in descending order from youngest to oldest geologic units: :*D-Troy Quartzite :*C- Mescal Limestone :*B-Dripping Spring Quartzite The Mesoproterozoic Dripping Spring Quartzite is a resistant, purple quartzite formation found in central and southeast Arizona, USA. It is a cliff-forming purplish unit found in the lower sections of the Apache Group, units of originally sedi ... :** Barnes Conglomerate (Globe, Arizona re ...

Astronomy Camp
Astronomy Camp is a science summer camp hosted by the University of Arizona's Alumni Association, and run by astronomer Don McCarthy. Many of the early camps took place at the Mount Lemmon Station Observatory atop Mount Lemmon, near Tucson, Arizona. On Mount Lemmon, the campers have access to a 12″, 20″, 40″ and 60″ telescope, and on the nearby Mount Bigelow site, a 61″ telescope. In recent years, the camp has also taken place at the Kitt Peak National Observatory, where the students have access to a wide variety of telescopes, including the 90″ Bok Telescope, the ARO 12m Radio Telescope The ARO 12m Radio Telescope (ARO12m or KP12m) is a 12-meter dish located on Kitt Peak, approximately from Tucson in Arizona at an elevation of . History The original dish was built in 1967 under the umbrella of the National Radio Astronomy O ..., and a variety of smaller instruments. At both locations, the telescopes and other equipment are used for hands-on learning and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catalina Sky Survey
Catalina Sky Survey (CSS; obs. code: 703) is an astronomical survey to discover comets and asteroids. It is conducted at the Steward Observatory's Catalina Station, located near Tucson, Arizona, in the United States. CSS focuses on the search for near-Earth objects, in particular on any potentially hazardous asteroid that may pose a threat of impact. Its counterpart in the southern hemisphere was the Siding Spring Survey (SSS), closed in 2013 due to loss of funding. CSS supersedes the photographic Bigelow Sky Survey. Mission The NEO Observations Program is a result of a United States 1998 congressional directive to NASA to begin a program to identify 1 kilometre (0.62 mile) or larger objects to around 90 percent confidence level or better. The Catalina Sky Survey, located at the Mount Lemmon Observatory in the Catalina Mountains north of Tucson, carries out searches for near-earth objects, NEOs, contributing to the congressionally mandated goal.

United States Forest Service
The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation's 154 national forests and 20 national grasslands. The Forest Service manages of land. Major divisions of the agency include the Chief's Office, National Forest System, State and Private Forestry, Business Operations, and Research and Development. The agency manages about 25% of federal lands and is the only major national land management agency not part of the U.S. Department of the Interior, which manages the National Park Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management. History The concept of national forests was born from Theodore Roosevelt's conservation group, Boone and Crockett Club, due to concerns regarding Yellowstone National Park beginning as early as 1875. In 1876, Congress formed the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. ...

White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3.

Space Shuttle
The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft where it was the only item funded for development. The first ( STS-1) of four orbital test flights occurred in 1981, leading to operational flights (STS-5) beginning in 1982. Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011. They launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST), conducted science experiments in orbit, participated in the Shuttle-''Mir'' program with Russia, and participated in construction and servicing of the International Space Station (ISS). ...

Air Defense Command
Aerospace Defense Command was a major command (military formation), command of the United States Air Force, responsible for continental air defense. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground F ...

Mount Lemmon Observatory
Mount Lemmon Observatory (MLO), also known as the Mount Lemmon Infrared Observatory, is an astronomical observatory located on Mount Lemmon in the Santa Catalina Mountains approximately northeast of Tucson, Arizona (US). The site in the Coronado National Forest is used with special permission from the U.S. Forest Service by the University of Arizona's Steward Observatory, and contains a number of independently managed telescopes. History The MLO site was first developed in 1954 as Mount Lemmon Air Force Station, a radar installation of the Air Defense Command. Upon transfer to the Steward Observatory 1970, the site was converted to an infrared observatory. Until 2003, a radar tower operated from Fort Huachuca was used to track launches from the White Sands Missile Range in New Mexico and Vandenberg Air Force Base in California.
