We have determined the origin of selected lunar ray segments utilizing Earth-based spectral and radar data as well as FeO, TiO 2, and optical maturity maps produced from Clementine UVVIS …

Sep 15, 2018 · This study mapped 27 lunar craters ranging from 10 m to 84 km in diameter and measured the number of rays, ray lengths, and OMAT of each. We developed a new empirical …

Sep 30, 2000 · Some lunar scientists have proposed that rays are dominated by primary crater ejecta, while others have emphasized the role of secondary cratering or even more exotic …

In essence, lunar rays are bright, elongated structures that emanate from impact craters, resembling rays of light radiating outwards. They are most prominently observed during the full …

Feb 8, 2020 · The lunar bright rays (also called crater rays) are filamentous high-albedo markings on the lunar surface. They come in various shapes, lengths, sizes, degrees of complexity, and …

Galilaei is a lunar impact crater located in the western Oceanus Procellarum.Some distance to the southeast is the crater Reiner, while to the south-southwest is Cavalerius.Northeast of the …

We have determined the origin of selected lunar ray segments utilizing Earth-based spectral and radar data as well as FeO, TiO2, and optical maturity maps produced from Clementine UVVIS …

In this study we mapped the ray systems of 27 lunar craters, ranging from 10m to 84km in diameter. For each ray system, we measured the number, length, and optical maturity index …

Jan 17, 2012 · Numerical simulations presented in this article suggest that crater rays surrounding about 12% of lunar craters (at least some of these rays) and craters on other airless bodies …

To explain Baldwin’s curve, we propose two hypotheses: 1) that the curvature of the Moon’s surface causes far-reaching rays to be longer than they would be given a flat surface, or 2) …

This detailed close-up of the full Moon features two prominent ray craters, Copernicus (upper left) and Tycho (lower right), each with extensive ray systems of light colored debris blasted out by …

Feb 4, 2025 · The authors calculated the ballistic flight of ejected debris that created the canyons. After flying over the lunar surface, the debris hit the lunar surface at speeds of about 1 …

Feb 7, 2025 · It took only minutes to dig out that huge crater and split the landscape to make two huge rifts that extend from the site. According to David Kring of the Lunar and Planetary …

2 days ago · On March 2, Blue Ghost made its landing at the moon's Mare Crisium within its 100-meter target, where it will begin surface operations over 14 days including subsurface drilling, …

4 days ago · The tricky lunar terrain: The moon is covered in dead volcanoes and deep craters, making it difficult to find flat landing zones. Without the assistance of human eyes inside the …

4 days ago · The Blue Ghost lunar lander, developed in partnership with NASA, aims to touch down on the moon early Sunday. ... crater-laden far side of the moon as it orbited roughly 62 …

4 days ago · Texas company pulls off first fully successful commercial moon landing 02:24. Firefly Aerospace's "Blue Ghost" lander dropped out of lunar orbit and swooped to a rocket-powered …
