“Because of the Moon’s lack of water, atmosphere, and tectonic plates, there is little erosion, and craters are found that exceed two billion years in age. The age of large craters is determined by the number of smaller craters contained within it, older craters generally accumulating more small, contained craters.

The smallest craters found have been microscopic in size, found in rocks returned to Earth from the Moon. The largest crater called such is about 290 kilometres (181 mi) across in diameter, located near the lunar South Pole. However, it is believed that many of the lunar maria were formed by giant impacts, with the resulting depression filled by upwelling lava.”

“This visualization uses a digital 3D model of the Moon built from global elevation maps and image mosaics by NASA’s Lunar Reconnaissance Orbiter mission. It was created to accompany a performance of Claude Debussy’s Clair de Lune by the National Symphony Orchestra Pops, led by conductor Emil de Cou, at the Kennedy Center for the Performing Arts in Washington, DC, on June 1 and 2, 2018, as part of a celebration of NASA’s 60th anniversary.

The visuals were composed like a nature documentary, with clean cuts and a mostly stationary virtual camera. The viewer follows the Sun throughout a lunar day, seeing sunrises and then sunsets over prominent features on the Moon. The sprawling ray system surrounding Copernicus crater, for example, is revealed beneath receding shadows at sunrise and later slips back into darkness as night encroaches.”

“Orbital ATK’s vision for the next step toward human space missions to Mars employs our flight-proven Cygnus advanced maneuvering spacecraft as a human habitat in cislunar space, the region between the Moon and Earth. In the early 2020s we would launch the initial habitat on NASA’s SLS rocket. Featuring a modular design, the habitat would serve both as a destination for crewed missions and as an unmanned testbed to prove-out the technologies needed for long-duration human space missions. The habitat is also envisioned as a base for lunar missions by international partners or commercial ventures. With additional habitation and propulsion modules, the habitat could be outfitted for a Mars pathfinder mission.”

“Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA’s Lunar Reconnaissance Orbiter spacecraft. As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.”

“Exploration Mission-1 (EM-1) will be the first integrated flight of NASA’s Space Launch System and Orion spacecraft and launch from the agency’s modernized spaceport in Florida. The uncrewed mission will send Orion thousands of miles beyond the Moon and is a critical flight test for NASA’s human deep space exploration goals. EM-1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the Moon and beyond.”

“In October 2017, The Lunar Reconnaissance Orbiter celebrates 100 lunar days of being at the Moon. Part 1 of this video series helps explain what a “lunar day” is, and what it means for the spacecraft’s mission to have been at the Moon for this period of time.”
