Parsec is a unit of distance defined as the distance at which one astronomical unit subtends an angle of one arcsecond, equating to about 3.26 light-years (206,265 AU). The term is often linked to Star Wars lore (Han Solo’s Kessel Run brag), but parsecs measure distance, not time, and the article breaks down the heliocentric parallax concept behind this measurement.
Crescent Space, a new commercial company launched by Lockheed Martin, has announced its entry into the lunar infrastructure sector. The company provides infrastructure-as-a-service for lunar missions, offering an initial service called Parsec, a cislunar communications and navigation network. Parsec uses a constellation of small lunar satellites that will collectively work to provide continuous connection between Earth and the people and assets in lunar orbit, as well as on the surface of the Moon. Crescent will own and operate the Parsec network upon launch of its first nodes in 2025.
