NASA
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 management f ...

ROTC
The Reserve Officers' Training Corps (ROTC ( or )) is a group of college- and university-based officer-training programs for training commissioned officers of the United States Armed Forces. Overview While ROTC graduate officers serve in all branches of the U.S. military, the U.S. Marine Corps, the U.S. Space Force, and the U.S. Coast Guard do not have their own respective ROTC programs; rather, graduates of Naval ROTC programs have the option to serve as officers in the Marine Corps contingent on meeting Marine Corps requirements. In 2020, ROTC graduates constituted 70 percent of newly commissioned active-duty U.S. Army officers, 83 percent of newly commissioned U.S. Marine Corps officers (through NROTC), 61 percent of newly commissioned U.S. Navy officers and 63 percent of newly commissioned U.S. Air Force officers, for a combined 56 percent of all active-duty officers in the Department of Defense commissioned that year. Under ROTC, a student may receive a competitive, mer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skylab 3
Skylab 3 (also SL-3 and SLM-2) was the second crewed mission to the first American space station, Skylab. The mission began on July 28, 1973, with the launch of NASA astronauts Alan Bean, Owen Garriott, and Jack Lousma in the Apollo command and service module on the Saturn IB rocket, and lasted 59 days, 11 hours and 9 minutes. A total of 1,084.7 astronaut-utilization hours were tallied by the Skylab 3 crew performing scientific experiments in the areas of medical activities, solar observations, Earth resources, and other experiments. The crewed Skylab missions were officially designated Skylab 2, 3, and 4. Miscommunication about the numbering resulted in the mission emblems reading "Skylab I", "Skylab II", and "Skylab 3" respectively. Crew Backup crew Support crew *Robert L. Crippen * Henry W.

Skylab 2
Skylab 2 (also SL-2 and SLM-1) was the first crewed mission to Skylab, the first American orbital space station. The mission was launched on an Apollo command and service module by a Saturn IB rocket on May 25, 1973, and carried NASA astronauts Pete Conrad, Joseph P. Kerwin, Paul J. Weitz to the station. The name Skylab 2 also refers to the vehicle used for that mission. The Skylab 2 mission established a twenty-eight-day record for human spaceflight duration. Furthermore, its crew were the first space station occupants ever to return safely to Earth – the only previous space station occupants, the crew of the 1971 Soyuz 11 mission that had crewed the Salyut 1 station for twenty-four days, died upon reentry due to unexpected cabin depressurization. The crewed Skylab missions were officially designated Skylab 2, 3, and 4. Miscommunication about the numbering resulted in the mission emblems reading "Skylab I", "Skylab II", and "Skylab 3" respectively. Crew Backup crew S ...

Skylab Medical Experiment Altitude Test
The Skylab Medical Experiment Altitude Test, or SMEAT, was a 56-day simulation of an American Skylab space mission from 26 July-19 September 1972 at NASA's Manned Spacecraft Center in Houston, Texas. The astronauts in the test were Bob Crippen, Karol Bobko, and William Thornton, who simulated space experiments, housekeeping and leisure activities in a hypobaric chamber. SMEAT provided a baseline for the in-orbit portion of biomedical experiments on Skylab. One of the benefits of SMEAT was discovering flaws in the urine handling system of Skylab, which allowed the problem to be fixed. The Skylab toilet went on to be widely praised by astronauts after the orbital missions. MSC invited the press in to film the crew entering the chamber. They could not talk to the press as they entered because they were wearing oxygen masks, but they did give a signed photo to one of the press that came out for the event. There were also a number of NASA officials there. SMEAT's main objective w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reese Air Force Base
Reese Technology Center is a research and business park located on the grounds of former Reese Air Force Base in western Lubbock at the unincorporated community of Reese Center. History Reese Technology Center began as the Lubbock Army Air Corps Advanced Flying School in 1942. It was renamed Lubbock Army Flying School in 1943 and then Lubbock Army Airfield later that same year. In 1949, it was renamed Reese Air Force Base in honor of a local West Texas pilot, Augustus F. Reese, Jr., who was killed in a bombing raid over Italy during World War II. Over the years, many milestones were accomplished at Reese Air Force Base, including a special pilot training program, the first flight simulator used in a training program, and a joint pilot training program with the Navy. More than 25,000 pilots, who fought in every conflict since World War II, were trained at Reese. In 1995, word reached the Lubbock community that Reese Air Force Base was on the Pentagon’s list for base closures. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA Astronaut Group 6
NASA Astronaut Group 6 (the "XS-11", "Excess Eleven") was a group of eleven astronauts announced by NASA on August 11, 1967, the second group of scientist-astronauts. Although Director of Flight Crew Operations Deke Slayton planned to hire 20 to 30 new scientist-astronauts, he did not expect any to fly because of a surplus of astronauts amid the looming dearth of post- Apollo program funding, exemplified by the concomitant devolution of the Apollo Applications Program into the Skylab Program. NASA found that only 11 of the 923 applicants were qualified, and hired all. When the group reported to the Manned Spacecraft Center, Slayton told them that "We don't need you around here". He offered to accept their resignations, and promised ground assignments if they did not quit, but warned them to not fool themselves that they would soon fly in space. With self-deprecation, the men named themselves the "XS-11", or "Excess Eleven". The group would be the last group selected by NASA for ...

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...
