Rayed crater
WebJan 18, 2024 · Rayed lunar craters have previously been used to compute impact flux rates, with the assumption often made that they formed in the past 1 Ga. We found 11 farside rocky craters with D ≥ 20 km formed in the past 1 Ga, compared with 28 to 32 farside rayed craters assumed to be this age (9, 10). WebWe report on the discovery of columnar jointing in Marte Valles, Mars. These columnar lavas were discovered in the wall of a pristine, 16-km-diameter impact crater and exhibit the features of terrestrial columnar basalts. There are discontinuous outcrops along the entire crater wall, suggesting that the columnar rocks covered a surface area of at least 200 km …
