Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit (apoapsis) by flying the vehicle through the atmosphere at the low point of the orbit (periapsis).
An areocentric orbit is an orbit around the planet Mars.
An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
Blok D (Блок Д meaning Block D) is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit.
Two-dimensional rotation can occur in two possible directions.
A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged.
The Darian calendar is a proposed system of time-keeping designed to serve the needs of any possible future human settlers on the planet Mars.
A densitometer is a device that measures the degree of darkness (the optical density) of a photographic or semitransparent material or of a reflecting surface.
Dust are fine particles of matter.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
A heat shield is designed to shield a substance from absorbing excessive heat from an outside source by either dissipating, reflecting or simply absorbing the heat.
For the Apple accessory see Twelve South High Resolution Imaging Science Experiment is a camera on board the Mars Reconnaissance Orbiter.
A lander is a spacecraft which descends toward and comes to rest on the surface of an astronomical body.
The following table is a list of Mars orbiters, consisting of space probes which were launched from Earth and are currently orbiting Mars.
There are a number of derelict orbiters around Mars whose location is not known precisely; there is a proposal to search for small moons, dust rings, and old orbiters with the Optical Navigation Camera on the Mars Reconnaissance Orbiter.
A low Earth orbit (LEO) is an orbit around Earth with an altitude of or less, and with an orbital period of between about 84 and 127 minutes.
A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials.
Mariner 9 (Mariner Mars '71 / Mariner-I) was an unmanned NASA space probe that contributed greatly to the exploration of Mars and was part of the Mariner program.
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury.
Mars 1M was a series of two unmanned spacecraft which were used in the first Soviet missions to explore Mars.
The Mars 2 was an unmanned space probe of the Mars program, a series of unmanned Mars landers and orbiters launched by the Soviet Union May 19, 1971.
Mars atmospheric entry is the entry into the atmosphere of Mars.
The Mars program was a series of unmanned spacecraft launched by the Soviet Union between 1960 and 1973.
Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit.
A Mars rover is an automated motor vehicle that propels itself across the surface of the planet Mars upon arrival.
The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.
An orbiter is a space probe that orbits a planet or other astronomical object.
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift).
A penetrometer is a device to test the strength of a material.
Planetary science or, more rarely, planetology, is the scientific study of planets (including Earth), moons, and planetary systems (in particular those of the Solar System) and the processes that form them.
The Proton-K, also designated Proton 8K82K after its GRAU index, 8K82K, was a Russian, previously Soviet, carrier rocket derived from the earlier Proton.
Ptolemaeus is a crater on Mars, found in the Phaethontis quadrangle at 46.21° south latitude and 157.6° west longitude.
A retrorocket (short for retrograde rocket) is a rocket engine providing thrust opposing the motion of a vehicle, thereby causing it to decelerate.
A robotic spacecraft is an uncrewed spacecraft, usually under telerobotic control.
A soft landing is any type of aircraft, rocket or spacecraft-lander landing that does not result in damage to/the destruction of the vehicle or anything on board.
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR) was a socialist state in Eurasia that existed from 1922 to 1991.
Space exploration is the discovery and exploration of celestial structures in outer space by means of evolving and growing space technology.
A space probe is a robotic spacecraft that does not orbit the Earth, but, instead, explores further into outer space.
Spacecraft Event Time (SCET) is the spacecraft-local time for events that happen at the spacecraft.
Various schemes have been used or proposed for timekeeping on the planet Mars independently of Earth time and calendars.
This timeline of artificial satellites and space probes includes unmanned spacecraft including technology demonstrators, observatories, lunar probes, and interplanetary probes.
An umbilical cable or umbilical is a cable and/or hose that supplies required consumables to an apparatus, diver or astronaut.
