Mare Spumans

Mare Spumans, whose Latin name means "foaming sea," is a lunar mare on the Moon's near side. It lies just south of Mare Undarum and forms part of the group of elevated mare regions situated within and around the Crisium basin, one of the Moon's prominent impact basins. Despite the word "mare," which historically means sea in Latin, the feature is not a body of liquid water. It is a broad plain of dark volcanic basalt produced by ancient lunar volcanism. The geological setting of Mare Spumans reflects several major stages of lunar history. Material forming the surrounding Crisium basin is assigned to the Nectarian epoch, a period associated with heavy impact activity early in the Moon's geological development. The basalt that fills the mare is attributed to the Upper Imbrian epoch, indicating that volcanic flooding occurred later, after the basin had formed. This relationship makes Mare Spumans an example of a lunar mare occupying an older impact-related structural setting and preserving evidence of subsequent volcanic activity. The crater Petit, formerly designated Apollonius W, is located along the mare's western rim. Petit is notable for its bright appearance and clearly defined system of ejecta rays, which extend across the surrounding surface and distinguish it from the darker mare material. A small bright-rayed crater in the northern part of Mare Spumans was also used as a navigation reference during the Apollo 11 mission. NASA astronaut Michael Collins tracked the feature during the mission's fourth revolution around the Moon. The observation was made with a sextant and supplied additional information to the spacecraft's onboard navigation computer. Collins informally called the landmark "KAMP," an acronym formed from the names of his three children and his wife: Kate, Ann, Michael, and Patricia. Mare Spumans has no corporate ownership, commercial product portfolio, headquarters, executive leadership, or operating markets. It is included here because the supplied canonical Wikipedia subject is the astronomical feature, not a consumer or corporate brand with a similar name.

Mare Spumans is a lunar mare on the near side of the Moon, positioned immediately south of Mare Undarum. Its name is derived from Latin and can be translated as "foaming sea," following the traditional lunar naming convention in which extensive dark plains were called maria, the Latin plural of mare. The designation describes a surface feature rather than a liquid environment: Mare Spumans is a solid basaltic plain formed by ancient volcanic eruptions. The mare occupies part of the complex geological environment associated with the Crisium basin. The basin's surrounding material dates to the Nectarian epoch, an early period in lunar geological history marked by substantial impact formation. After the basin was created and its surrounding terrain established, volcanic basalt accumulated in the depression and adjacent elevated mare areas. The basalt in Mare Spumans is assigned to the Upper Imbrian epoch, showing that the volcanic resurfacing postdated the formation of the older basin material. The feature is therefore significant as a record of the interaction between large impact structures and later lunar volcanism. Several craters provide geographic reference points around the mare. Petit lies on the western rim. The crater was formerly identified as Apollonius W and is visually distinctive because of its bright interior and prominent ray system. The rays consist of lighter ejecta distributed around the crater, contrasting with the darker basaltic surface of the mare. Mare Spumans also has a connection with the Apollo 11 mission. A small bright-rayed crater in its northern section was designated landmark A-1/11 at approximately 1.7981° north latitude and 65.0741° east longitude. During Apollo 11's fourth revolution, Michael Collins observed and tracked the landmark using the spacecraft's sextant. The resulting measurements were entered into the onboard computer to improve orbital information. Collins used the informal name KAMP for the crater, deriving it from the first names of his three children and his wife: Kate, Ann, Michael, and Patricia. The subject is an astronomical landform and not a company, product line, retailer, or other commercial brand. Consequently, there are no established corporate milestones, products, marketing campaigns, executives, scandals, ownership records, or financial disclosures associated with Mare Spumans.
