Gasa Crater is an impact crater in the Phaethontis 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. Gullies are evident in the images. It is now believed that the impact that created Gasa happened in a larger crater whose floor was covered with debris-covered glaciers.〔Schon, S. and J. Head. 2012.
