The Viking program consisted of a pair of identical American space probes, Viking 1 and Viking 2, which landed on Mars in 1976. Each spacecraft was composed of two main parts: an orbiter designed to photograph the surface of Mars from orbit, and a lander designed to study the planet from the surface. The orbiters also served as communication relays for the landers once they touched down.
Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Moon landings were hoaxes staged by NASA, possibly with the aid of other organizations. The most notable claim is that the six crewed landings (1969–1972) were faked and that twelve Apollo astronauts did not actually walk on the Moon. Various groups and individuals have made claims since the mid-1970s that NASA and others knowingly misled the public into believing the landings happened, by manufacturing, tampering with, or destroying evidence including photos, telemetry tapes, radio and TV transmissions, and Moon rock samples.
The Lyndon B. Johnson Space Center (JSC) is NASA's center for human spaceflight, where human spaceflight training, research, and flight control are conducted. It was built and leased to NASA by Joseph L. Smith & Associates, Inc. It was renamed in honor of the late US president and Texas native, Lyndon B. Johnson, by an act of the United States Senate on February 19, 1973.
James Edwin Webb was an American government official who served as Undersecretary of State from 1949 to 1952. He was also the second appointed administrator of NASA from February 14, 1961, to October 7, 1968. Webb oversaw NASA from the beginning of the Kennedy administration through the end of the Johnson administration, thus overseeing each of the critical first crewed missions throughout the Mercury and Gemini programs until days before the launch of the first Apollo mission. He also dealt with the Apollo 1 fire.
Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions. Planetary protection reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated.
The Lunar Crater Observation and Sensing Satellite (LCROSS) was a robotic spacecraft operated by NASA. The mission was conceived as a low-cost means of determining the nature of hydrogen detected at the polar regions of the Moon. Launched immediately after discovery of lunar water by Chandrayaan-1, the main LCROSS mission objective was to further explore the presence of water in the form of ice in a permanently shadowed crater near a lunar polar region. It was successful in confirming water in the southern lunar crater Cabeus.
Newton is a large crater on Mars, with a diameter close to 300 km. It is located south of the planet's equator in the heavily cratered highlands of Terra Sirenum in the Phaethontis quadrangle. The crater was named in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN) in honor of British physicist Sir Isaac Newton.
Last Chance is a layered rock outcrop found within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars, discovered by the Mars Exploration Rover Opportunity in March 2004. The rock lies within the outcrop near the rover's landing site at Meridiani Planum, Mars.
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet". The latter refers to the effect of the iron oxide prevalent on Mars's surface, which gives it a striking reddish appearance in the sky. Mars is a terrestrial planet with a thin atmosphere, with surface features such as impact craters, valleys, dunes, and polar ice caps.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research.
The Aeolis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Aeolis quadrangle is also referred to as MC-23 . The Aeolis quadrangle covers 180° to 225° W and 0° to 30° south on Mars, and contains parts of the regions Elysium Planitia and Terra Cimmeria. A small part of the Medusae Fossae Formation lies in this quadrangle.
The NASA Astronaut Corps is a unit of the United States National Aeronautics and Space Administration (NASA) that selects, trains, and provides astronauts as crew members for U.S. and international space missions. It is based at Johnson Space Center in Houston, Texas.
Space nursing is a specialty that works with astronauts to determine medical fitness for their missions, equips NASA team members to handle emergencies in orbit and researches the effects of space travel on the human body. The career got its start during the space race of the 1960s and has grown—both in terms of number of people in the field and knowledge base—ever since. Research conducted by medical professionals in the aeronautics field has led to many breakthroughs in disease treatment of earthbound patients and the discipline continually develops new technology to make space medicine more effective.
Astronauts are exposed to approximately 50-2,000 millisieverts (mSv) while on six-month-duration missions to the International Space Station (ISS), the Moon and beyond. The risk of cancer caused by ionizing radiation is well documented at radiation doses beginning at 100mSv and above.
Link is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The outcrop was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue on September 2, 2012, and was named after a significant rock formation in the Northwest Territories of Canada. The "approximate" site coordinates are: 4.59°S 137.44°E.
Goulburn, also known as Goulburn Scour, is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The outcrop was encountered by the Curiosity rover on landing at the Bradbury Landing on August 6, 2012 and is named after a two-billion year-old sequence of rocks in Northern Canada. The "approximate" site coordinates are: 4.59°S 137.44°E.
NASA International Space Apps Challenge is annual NASA's global hackathon, first held in April 2012, and serves as innovation incubation and civic engagement program. NASA and its partners put out challenges relating to current work for which space enthusiasts around the world of all backgrounds can develop innovative solutions, particularly focusing on use of NASA data and promoting education. The project, formerly run by NASA's Office of the Chief Information Officer, is part of NASA's Earth Science Mission Directorate and is a part of the Open Government Initiative founded under President Barack Obama "creating an unprecedented level of openness in Government." It also fulfills the United States’ commitments to the Open Government Partnership.
The Ocean Worlds Exploration Program (OWEP) is a NASA program to explore ocean worlds in the outer Solar System that could possess subsurface oceans to assess their habitability and to seek biosignatures of simple extraterrestrial life.
Anming Hu is a Chinese-Canadian who had worked as an associate professor in the Department of Mechanical, Aerospace and Biomedical Engineering at the University of Tennessee, Knoxville (UTK) from 2013 to February 2020 when he was charged with fraud, after which UT suspended him. He was arrested on February 27, 2020, and charged with fraud under a 2011 law the Donald Trump administration used to target professors and researchers working at American universities as part of the "China Initiative" on combating economic espionage. Hu was accused of not disclosing his association with a Chinese university; on September 9, 2021, the trial resulted in acquittal, thus Hu was cleared of all charges. On February 1, 2022, he returned to his lab at UTK.
