2024年1月17日 America and the Sea of Serenity Image Credit & Copyright: Gene Cernan, Apollo 17, NASA; Anaglyph by Patrick Vantuyne Explanation: Get out your red/blue glasses and check out this stereo view of another world. The scene was recorded by Apollo 17 mission commander Eugene Cernan on December 11, 1972, one orbit before descending to land on the Moon. The stereo anaglyph was assembled from two photographs (AS17-147-22465, AS17-147-22466) captured from his vantage point on board the Lunar Module Challenger as he and Dr. Harrison Schmitt flew over Apollo 17’s landing site in the Taurus-Littrow Valley. The broad, sunlit face of the mountain dubbed South Massif rises near the center of the frame, above the dark floor of Taurus-Littrow to its left. Piloted by Ron…

2023年5月13日 Apollo 17: The Crescent Earth Image Credit: Apollo 17, NASA; Restoration – Toby Ord Explanation: Our fair planet sports a curved, sunlit crescent against the black backdrop of space in this stunning photograph. From the unfamiliar perspective, the Earth is small and, like a telescopic image of a distant planet, the entire horizon is completely within the field of view. Enjoyed by crews on board the International Space Station, only much closer views of the planet are possible from low Earth orbit. Orbiting the planet once every 90 minutes, a spectacle of clouds, oceans, and continents scrolls beneath them with the partial arc of the planet’s edge in the distance. But this digitally restored image presents a view so far only achieved by 24…

2022年12月17日 Apollo 17 VIP Site Anaglyph Image Credit: Gene Cernan, Apollo 17, NASA; Anaglyph by Erik van Meijgaarden Explanation: Get out your red/blue glasses and check out this stereo scene from Taurus-Littrow valley on the Moon! The color anaglyph features a detailed 3D view of Apollo 17’s Lunar Rover in the foreground — behind it lies the Lunar Module and distant lunar hills. Because the world was going to be able to watch the Lunar Module’s ascent stage liftoff via the rover’s TV camera, this parking place was also known as the VIP Site. Fifty years ago, in December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon, while colleague Ronald Evans orbited overhead. The crew returned…

2022年12月14日 Lunar Dust and Duct Tape Image Credit: Apollo 17, NASA Explanation: Why is the Moon so dusty? On Earth, rocks are weathered by wind and water, creating soil and sand. On the Moon, the history of constant micrometeorite bombardment has blasted away at the rocky surface creating a layer of powdery lunar soil or regolith. For the Apollo astronauts and their equipment, the pervasive, fine, gritty dust was definitely a problem. Fifty years ago, on the lunar surface in December 1972, Apollo 17 astronauts Harrison Schmitt and Eugene Cernan needed to repair one of their rover’s fenders in an effort to keep the rooster tails of dust away from themselves and their gear. This picture reveals the wheel and fender of their dust covered…

2022年2月6日 Blue Marble Earth Image Credit: NASA, Apollo 17 Crew Explanation: Welcome to planet Earth, the third planet from a star named the Sun. The Earth is shaped like a sphere and composed mostly of rock. Over 70 percent of the Earth’s surface is water. The planet has a relatively thin atmosphere composed mostly of nitrogen and oxygen. The featured picture of Earth, dubbed The Blue Marble, was taken from Apollo 17 in 1972 and features Africa and Antarctica. It is thought to be one of the most widely distributed photographs of any kind. Earth has a single large Moon that is about 1/4 of its diameter and, from the planet’s surface, is seen to have almost exactly the same angular size as the Sun….
