The f-number of an optical system (such as a camera lens) is the ratio of the system's focal length to the diameter of the entrance pupil.
The far side of the Moon (sometimes figuratively known as the dark side of the Moon) is the hemisphere of the Moon that always faces away from Earth.
A flying-spot scanner (FSS) uses a scanning source of a spot of light, such as a high-resolution, high-light-output, low-persistence cathode ray tube (CRT), to scan an image.
Gagarin's Start (Гагаринский старт, Gagarinskiy start) is a launch site at Baikonur Cosmodrome in Kazakhstan, used for the Soviet space program and now managed by Roscosmos State Corporation.
A geocentric orbit or Earth orbit involves any object orbiting Planet Earth, such as the Moon or artificial satellites.
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense.
A gyroscope (from Ancient Greek γῦρος gûros, "circle" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientation and angular velocity.
A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth.

The Luna programme (from the Russian word Луна "Luna" meaning "Lunar" or "Moon"), occasionally called Lunik or Lunnik by western media, was a series of robotic spacecraft missions sent to the Moon by the Soviet Union between 1959 and 1976.
The lunar south pole is of special interest to scientists because of the postulated occurrence of water ice in permanently shadowed areas around it.
Mare Desiderii ("Sea of Dreams") was an area of the Moon named after Luna 3 returned the first pictures of the far side.
Mare Ingenii ("sea of cleverness") is one of the few lunar mare features on the far side of the Moon.
Mare Moscoviense ("Sea of Moscow") is a lunar mare that sits in the Moscoviense basin.
A micrometeoroid is a tiny meteoroid; a small particle of rock in space, usually weighing less than a gram.
The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.

The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.
Photosensors or photodetectors are sensors of light or other electromagnetic energy.
Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals.
Photomultiplier tubes (photomultipliers or PMTs for short), members of the class of vacuum tubes, and more specifically vacuum phototubes, are extremely sensitive detectors of light in the ultraviolet, visible, and near-infrared ranges of the electromagnetic spectrum.
