At more than 4,000 km (2,500 mi) long, 200 km (120 mi) wide and up to 7 km (23,000 ft) deep, [3] [4] Valles Marineris is the largest canyon in the Solar System. [5] Valles Marineris is located along the equator of Mars, on the east side of the Tharsis Bulge, and stretches for
The formation was first photographed by Viking Orbiter 1. A second "happy face crater", smaller than Galle and located at 45.1°S, 55.0°W in Nereidum Montes , was discovered by the Mars Reconnaissance Orbiter on January 28, 2008.
One scientific paper and various press reports claimed in February 2022 that at 2.93 times the significant wave height, the Ucluelet wave set a record as the most extreme rogue wave ever recorded at the time in terms of its height in proportion to surrounding waves, and that scientists estimated that a wave about three times higher than those ...
