About
Today's image shows the channel floor of Mawrth Vallis. Of all the channels carved by flowing water on Mars, one of the more unusual is Mawrth Vallis, whose name comes from the Welsh word for Mars. Mawrth Vallis winds through northwest Arabia Terra for some 640 kilometers (400 miles) before emptying into Acidalia Planitia on the edge of the vast northern lowlands. Unlike many outflow channels that start in regions of chaotic terrain, Mawrth Vallis just appears and then grows deeper as it heads downstream, holding a width of approximately 15 km (9 mi) until it widens near its mouth at Chryse Planitia. And the floor of the channel is a much more complex surface than most channels, with layers — NASA JPL · 2022. ABD devlet eseri: kamu mali, ticari islerde de serbestce kullanilabilir.
