28.Galilaei

The western edge of visible part of the Moon, and of Oceanus Procellarum. Observers with larger telescopes can have a look at the rilles on the floor of Hevelius and Rima Cardanus. Here we find a unique formation, one of a kind, Reiner Gamma.

BOHR - Niels H. D. Bohr. (1885 - 1962) Danish Physicist, creator of the Bohr Atomic Model. Theory on the Periodic system, winner Nobel price 1922.

Crater. (73Km /43Mi ø ) (Debt: 4,090m /13,419ft) (12.8°N, 86.4°W) Crater in the area of libration, difficult to observe.

CARDANUS - Geronimo Cardano. (1501 - 1576) Italian mathematician, physician, philosopher and astrologer.

Crater. (50Km /32Mi ø ) (Dept: 2,300m /7,000ft) (13.2°N, 72.4°W) Connected with Krafft through a rille. (See Chart 17)

CAVALERIUS - Francesco Bonaventura Cavalieri. (1598 - 1647) Italian mathematician and astronomer. Pupil of Galileo Galilaei.

Crater. (60Km /38Mi ø ) (Dept: 3,000m /9,100ft) (5.1° N, 66.8° W) Clearly pronounced crater. Flat floor with small central mountain. It nearly joins the northern rim of Hevelius to the south.

GALILAEI - Galilaei Galileo (1564 - 1642) Italian astronomer and mathematician, physicist, founder of modern natural sciences. Builder of a telescope with which he observe the Moon, Jupiter's Moons and the stars. He defended the theory of Copernicus.

Crater. (15,5Km /9Mi ø ) (Dept: 2,000m / 6,100ft) (10.5°N, 62.7°W). Circular formation, sharply edged.

HEDIN - Sven Hedin. (1865 - 1952) Swedish scientist and explorer, expeditions to central Asia.

Crater. (148Km /87Mi ø ) (Dept: 1,250m /4,101ft) (2.9°N, 76.5°W) Remains of a walled plain.

HEVELIUS - Johannes Hevelius (1611 - 1687) Mayor of Danzig, astronomer, selenographer, founder of lunar topography. Described ten new constellations. Seven of which still carry the names he gave them.

Crater. (109Km /64Mi ø ) (Depth 1.800 m /5,905ft) (2°12′N, 67°18′W) Large flat floor supporting Hevelius A to the North. Small central mountain. Forms a pair with Cavalerius.

OCEANUS PROCELLARUM - See Map 29.

OLBERS - Heinrich Wilhelm Matthias Olbers. (1758 - 1840) German physician and astronomer.

Crater (74 Km /44Mi ø ) (Dept: 3,000m /9,100ft) (7.4°N 75.9°W) Remains of an eroded walled plain, supporting Olbers A to the North-West Olbers K to the West and Olbers B to the East. High walls. Flat floor filled with lava.

PLANITIA DESCENSUS - Plain of descent. (1967) Location of the first soft landing on the Moon by Luna  9 on  February 3, 1966.

Crater floor  (7.13°N, 64.37°W)  Northeast of Cavalerius crater we find the site designated Planitia Descensus, the landing site of the Russian Luna 9 probe, the first vehicle to soft-land on the Moon. It lies among some low ridges along the edge of the Oceanus Procellarum.

REINER GAMMA - Vincentio Reinieri. (1606 – 1647) Italian mathematician and astronomer. He was a friend and disciple of Galileo Galilei.

Crater. (70km /43.5Mi ø ) (7.5°N, 59.0°W) Formation composed of a deposit of very clear materials in the form of diamond of cards. Seems to be linked with a completely eroded ghost crater.  

VASCO DA GAMA - Vasco Da Gama. (ca. 1460 – 1524) Portuguese explorer. The commander of the first fleet of ships to sail directly from Europe to India.

Crater. (93Km /58Mi ø ) (Dept: 2,780m /9121ft) (13.9°N, 83.9°W) The northern and southern parts of the rim of Vasco da Gama have been heavily eroded by impacts, with the western and eastern rims being more intact.
