Palo is an African diasporic religion that developed in Cuba during the late 19th or early 20th century. It draws heavily upon the traditional Kongo religion of Central Africa, and from Catholicism and Spiritism. Central to Palo is the nganga, usually made from an iron cauldron. Many nganga are regarded as material manifestations of ancestral or nature deities known as mpungu. The nganga may contain a wide range of objects, among the most important being sticks and human remains, the latter called nfumbe. In Palo, the presence of the nfumbe means that the spirit of that dead person inhabits the nganga and serves the possessor. The nganga is "fed" with the blood of sacrificed animals and other offerings. Palo is most heavily practiced in eastern Cuba although it is found throughout the island and abroad, including in other parts of the Americas such as Venezuela, Mexico, and the United States. Palo adherents have faced problems with police for grave robbery to procure human bones. (Full article...)
The Reduced Gravity Walking Simulator was a facility developed by NASA in the early 1960s to study human movement under simulated lunar gravity conditions. It was located at NASA's Langley Research Center in Virginia and was designed to prepare astronauts for the Moon landings during the Apollo program. The simulator was tilted at a 9.5-degree angle from the vertical and test subjects were suspended on their side by cables at the same angle. This set-up allowed the trainees to walk along the surface while experiencing only one-sixth of Earth's gravity. It was also used to study the physiological effects on the astronaut's body during movement. In total, 24 astronauts used the simulator to train for lunar missions, including all three astronauts of the Apollo 1 mission. This photograph, taken in 1963, shows a test subject being suited up by two technicians on the Reduced Gravity Walking Simulator.
