The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases. This characteristic is used to define its limits: it begins at the top of the stratosphere, and ends at the mesopause, which is the coldest part of Earth's atmosphere, with temperatures below −143 °C. The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary is usually located at altitudes from 50 to 65 km above sea level, and the upper boundary is usually from 85 to 100 km.
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft.
Space debris are defunct human-made objects in space—principally in Earth orbit—which no longer serve a useful function. These include derelict spacecraft—nonfunctional spacecraft and abandoned launch vehicle stages—mission-related debris, and particularly numerous in Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft. In addition to derelict human-made objects left in orbit, other examples of space debris include fragments from their disintegration, erosion and collisions or even paint flecks, solidified liquids expelled from spacecraft, and unburned particles from solid rocket motors. Space debris represents a risk to spacecraft.
China National Space Administration is the government agency of the People's Republic of China that is responsible for civil space administration and international space cooperation, including organizing or leading foreign exchanges and cooperation in the aerospace field. An administrative agency under the Ministry of Industry and Information Technology, its headquarters are located in Haidian, Beijing.
A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies away from common operational orbits. One significant graveyard orbit is a supersynchronous orbit well beyond geosynchronous orbit. Some satellites are moved into such orbits at the end of their operational life to reduce the probability of colliding with operational spacecraft and generating space debris.
Institute of Space and Astronautical Science (ISAS) is a Japanese national research organization of astrophysics using rockets, astronomical satellites and interplanetary probes which played a major role in Japan's space development. Since 2003, it is a division of Japan Aerospace Exploration Agency (JAXA).
The Aerospace Corporation is an American nonprofit corporation that operates a federally funded research and development center (FFRDC) in El Segundo, California. The corporation provides technical guidance and advice on all aspects of space missions to military, civil, and commercial customers. As the FFRDC for national-security space, Aerospace works closely with organizations such as the United States Space Force and the National Reconnaissance Office (NRO) to provide "objective technical analyses and assessments for space programs that serve the national interest". Although the USSF and NRO are the primary customers, Aerospace also performs work for civil agencies such as NASA and NOAA as well as international organizations and governments in the national interest.
The NASA Orbital Debris Program Office is located at the Johnson Space Center and is the lead NASA center for orbital debris research. It is recognized world-wide for its leadership in addressing orbital debris issues. The NASA Orbital Debris Program Office has taken the international lead in conducting measurements of the environment and in developing the technical consensus for adopting mitigation measures to protect users of the orbital environment. Work at the center continues with developing an improved understanding of the orbital debris environment and measures that can be taken to control its growth.
The abbreviation IADC may stand for:
The Orbital Debris Co-ordination Working Group (ODCWG) is one of the working groups of the International Organization for Standardization's Technical Committee 20/Subcommittee 14 TC20/SC14 "Spacecraft Systems and Operations".
The following outline is provided as an overview of and topical guide to the aerospace field:
Cartosat-2 is an Earth observation satellite in a Sun-synchronous orbit and the second of the Cartosat series of satellites. The satellite was built, launched and maintained by the Indian Space Research Organisation (ISRO). Weighing around 680 kg at launch, its applications will mainly be towards cartography in India. It was launched by the Polar Satellite Launch Vehicle PSLV-C7 launch vehicle on 10 January 2007.
Space policy is the political decision-making process for, and application of, public policy of a state regarding spaceflight and uses of outer space, both for civilian and military purposes. International treaties, such as the 1967 Outer Space Treaty, attempt to maximize the peaceful uses of space and restrict the militarization of space.
Tiangong-1 was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a crewed laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life.
The Netherlands Space Office (NSO) is the space agency of the Netherlands.
Vipparthi Adimurthy is the ISRO Honorary Distinguished Professor, VSSC. He was the former Satish Dhawan Professor and Dean of Research at the Indian Institute of Space Science and Technology (IIST). Prior to joining IIST, Adimurthy held the post of associate director at the Vikram Sarabhai Space Centre, a major facility center of Indian Space Research Organisation (ISRO). He is known for his contributions to the rocket technology and space dynamics. He is a recipient of Padma Shri from the Government of India. Murthy is the Mission Concept Designer, for India's Mars Orbiter Mission.
INSAT-4B was an Indian communications satellite which forms part of the Indian National Satellite System. Launched in 2007, it was placed in geostationary orbit at a longitude of 93.48° East.
SLOSHSAT-FLEVO is a microsatellite launched to investigate the dynamics of fluids in microgravity. FLEVO stands for Facility for Liquid Experimentation and Verification in Orbit. Multiple sensors were used to monitor the behavior of water in an instrumented tank and how sloshing affects the attitude control of launchers and space vehicles.
Space sustainability aims to maintain the safety and health of the space environment.
