2020 In Spaceflight
This article documents notable spaceflight events during the year 2020. Overview Exploration of the Solar System Three missions to Mars were launched in 2020, including two rovers, two orbiters, and a lander. NASA has launched the Mars 2020 mission, which includes the ''Perseverance'' rover and ''Ingenuity'' helicopter, and will cache samples for eventual return to Earth. The China National Space Administration (CNSA) has launched its Tianwen-1 mission, which includes an orbiter, a lander, a small rover and a group of deployable and remote cameras; it is China's first mission to another planet using its own delivery vehicle. Finally, the United Arab Emirates, in partnership with American universities, has launched the Hope Mars Mission orbiter on a Japanese rocket. In November, China launched Chang'e 5, the first sample-return mission to the Moon since Luna 24 in 1976. Chang'e 5 used the recently developed Long March 5 heavy-lift rocket. The mission performed t ...

Graphite-Epoxy Motor
The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters first developed in the late 1980s and used from 1990 to the present day. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is currently produced by Northrop Grumman Space Systems. GEM boosters were previously used on the Delta II, Delta III, and Delta IV launch vehicles, and are currently used on the Atlas V. A new variant, the GEM 63XL, is slated to fly as part of the Vulcan Centaur launch vehicle no earlier than the 1st quarter of 2023. Variants Active GEM 63 The GEM 63 was developed by Orbital ATK as a low-cost drop-in replacement for the Aerojet Rocketdyne AJ-60A solid rocket booster used on the Atlas V. Its overall dimensions are very similar to that of the motor it replaces. The Atlas V first flew with the GEM 63 in 2020 on the NROL-101 launch. The booster offers higher performance at about half ...

National Reconnaissance Office
The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA. NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, south of the Washington Dulles International Airport. The Director of the NRO reports to both the Director of National Intelligence and the Secretary of Defense. The NRO's federal workforce is a hybrid o ...

Medium Earth Orbit
A medium Earth orbit (MEO) is an geocentric orbit, Earth-centered orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between above sea level.''Catalog of Earth Satellite Orbits''
NASA Earth Observatory. 4 September 2009. Accessed 2 May 2021.
The boundary between MEO and LEO is an arbitrary altitude chosen by accepted convention, whereas the boundary between MEO and HEO is the particular altitude of a geosynchronous orbit, in which a satellite takes 24 hours to circle the Earth, the same period as the Earth’s own rotation. All satellites in MEO have an orbital period of less than 24 hours, with the minimum period (for a circular orbit at the lowest MEO altitude) about 2 hours. Satellites in MEO or ...

List Of NRO Launches
This is a list of NRO Launch (NROL) designations, i.e. satellites operated by the United States National Reconnaissance Office. Those missions are generally classified, so that their exact purposes and orbital elements are not published. However, amateur astronomers have managed to observe most of the satellites, and leaked information has led to the identification of many of the payloads.

On 5 March 2021, NASA named the landing site of the rover Octavia E. Butler Landing. As of , ''Perseverance'' and ''Ingenuity'' have been on Mars for sols ( total days; '). ''Perseverance'' will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. It will cache sample containers along its route for retr ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) 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. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ...
