Kasei Vallisとは 意味・読み方・使い方

Kasei, which means "Mars" in Japanese, is a giant river valley in the Lunae Palus quadrangle, on Mars. It is located at 24.6° north latitude and 65° west longitude. One of the most significant features of the Lunae Palus region, Kasei Valles, is one of the largest outflow channels on Mars. Like other outflow channels, it was likely carved by liquid water, probably during gigantic floods. Kasei is about 2,400 km (1,500 mi) long, and some sections of Kasei Valles are 300 km (190 mi) wide. It begins in Echus Chasma, near Valles Marineris, and empties into Chryse Planitia, not far from where Viking 1 landed. Sacra Mensa, a large tableland, divides Kasei into a northern and southern channel. Scientists suggest it was formed several episodes of flooding and possibly by some glacial activity.
