LoRa (short for Long Range) is a low-power, long-range wireless communication technology that is used in the aerospace industry for a variety of applications. It is a type of wireless radio frequency (RF) technology that uses a modulation scheme called chirp spread spectrum (CSS) to transmit data over long distances using very low power levels.

LOS in the space industry context stands for "Line of Sight." It refers to the direct visual or radio frequency (RF) path between a transmitting and receiving antenna or communication device. LOS is a critical concept in space communications, as it determines whether two objects, such as satellites or spacecraft, can establish a connection or maintain uninterrupted communication. Understanding LOS is vital for planning and maintaining space missions, satellite operations, and ground-based control centers.

Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology.

Lunar Gateway in the space industry context refers to a planned space station that will orbit the Moon, serving as a multi-purpose outpost for lunar exploration, scientific research, and as a stepping stone for future deep-space missions, including human missions to Mars. The Gateway is a collaborative project led by NASA, with significant contributions from international partners, including the European Space Agency (ESA), the Canadian Space Agency (CSA), the Japan Aerospace Exploration Agency (JAXA), and Roscosmos. The Lunar Gateway is part of NASA’s Artemis program, which aims to return humans to the Moon and establish a sustainable human presence by the end of the decade.
