Gasa Crater

Gasa Crater, as seen by CTX camera (on Mars Reconnaissance Orbiter). Note: Gasa Crater is the smaller crater. It is believed the impact that created Gasa occurred in a debris-covered glacier.

Gasa is an impact rayed crater in the Eridania quadrangle on Mars at 35.68° S and 230.72° W. and is 6.5 km in diameter. Its name was approved in 2009, and it was named after a place in Bhutan.[1] Gullies are evident in the images.[2] It is now believed that the impact that created Gasa happened in a larger crater whose floor was covered with debris-covered glaciers.[3]

Two nearby unnamed craters are located, one in the west and the other in the south with a tall rim and a central peak, almost equal distance but the southern one is closer. Its nearby small named crater is Pursat which is located south-southeast. To the west is Morpheos Rupes which is about 400 km long.
