Vital Alsar Pacific Raft Expeditions
Between 1966 and 1973, Spanish explorer Vital Alsar led three expeditions to cross the Pacific Ocean by raft – La Pacífica in 1966, La Balsa in 1970 and Las Balsas in 1973. Travelling from Ecuador, South America, to Australia, the first expedition failed, but the second and third succeeded, both setting the record for the longest known raft voyages in history – and respectively. Aim The aim of the expeditions was to prove that the Pacific Islands could have been populated by migrations from South America in the centuries before the Spanish Conquistadors arrived. Alsar maintained that ancient mariners knew the Pacific currents and winds as well as modern humans know road maps. It was hoped to double the distance achieved by the Kon-Tiki expedition, the 1947 raft crossing by Thor Heyerdahl from South America to the Polynesian islands. Like the Kon-Tiki expedition, the aim was to see if a raft made from the materials available in the 16th century in pre-Columbian South A ...

Full Moon
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic coordinate system, ecliptic longitudes of the Sun and Moon opposition (astronomy), differ by 180°). This means that the lunar hemisphere facing Earth—the near side of the Moon, near side—is completely sunlit and appears as an approximately circular disk. The full moon occurs roughly once a month. The time interval between a full moon and the next repetition of the same phase, a Lunar month#Synodic month, synodic month, averages about 29.53 days. Therefore, in those lunar calendars in which each month begins on the day of the new moon, the full moon falls on either the 14th or 15th day of the lunar month. Because a calendar month consists of a Natural number, whole number of days, a month in a lunar calendar may be either 29 or 30 days long. Characteristics A full moon is often thought of as an ...
