If certain assumptions, discussed below, are granted, rela-tive ages of lunar craters can be determined by the degree of freshness of their major topographic components such as the rim crests, walls, and surrounding rim deposits.

Counting craters had let us calculate relative ages (for example, the heavily cratered lunar highlands were older than the dark lava plains), but scientists could not measure the actual age in years. Some thought that the ages were as young as those of Earth’s surface, which has been resurfaced by many geological events.

Jan 29, 2025 · The crater is in the southern lunar highlands and is approximately 53 miles (85 km) in diameter and 110 million years old. A slump terrace has formed in the northern half of the young Giordano Bruno crater, seen here at sunset.

Apr 2, 2024 · Intercomparison of these independently observed populations of young craters can reveal much about the evolution of the lunar surface and its materials. Here we present a new database of both rayed and rocky craters with diameter ≥5 km on …

Scientists count craters to determine how old a lunar surface is. Young craters have crisp rims and lie on top of other craters. Older craters have softer rims and their ejecta and rays may be covered with fresh craters.

Dec 11, 2012 · Craters on the Moon, young and old. Click to enselenate. This shot, taken by NASA’s Lunar Reconnaissance Orbiter, shows a relatively young crater carved into ancient geology.

Oct 13, 2014: NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old.

Jan 23, 2019 · A team of scientists used NASA's Lunar Reconnaissance Orbiter data to study the Moon’s craters, scaled by size and color-coded by age (blue indicates those younger than 290 million years), to understand the impact history of the Earth.

Today's Featured Image highlights contrasting features of young (lower right) and old (upper left) craters with almost the same diameters (about 450 meters). These two craters are found in the western portion of Mare Frigoris, 23 km south of La Condamine S crater.

Feb 17, 2010 · Accurately defining the ages of young lunar craters, such as Giordano Bruno, is vitally important for understanding the impact flux rate over the past few million years throughout the inner Solar System, including on Earth.

May 24, 2016 · A Southwest Research Institute-led team of scientists discovered two geologically young craters — one 16 million, the other between 75 and 420 million, years old — in the Moon’s darkest regions.

May 23, 2016 · A Southwest Research Institute-led team of scientists discovered two geologically young craters – one 16 million, the other between 75 and 420 million, years old in the Moon’s darkest regions.

Using data from the LAMP instrument aboard the Lunar Reconnaissance Orbiter, a Southwest Research Institute-led team of scientists discovered two geologically young craters — one (right) 16...

May 14, 2011 · “Old and young craters have different roughness properties—they are rougher on some scales and smoother on others,” says Rosenburg. That’s because the older craters have been pummeled for eons by meteorites that pit and mar the site of the original impact, changing the original shape of the crater.

5 days ago · Decades-old data from Apollo missions had previously detected shallow moonquakes. The Apollo Lunar Seismic Experiment recorded 28 shallow moonquakes with magnitudes of approximately 1.5 to 5.

Feb 17, 2017 · It's a young crater has craters go on the moon, being less than a billion years old. This is why it looks so crisp with a sharp rim not yet eroded by smaller meteorite impacts. Just below it is the larger and much older crater Maginus (168km diameter) whose age may stretch back as far as 4.5 billion years.
