Hagal is the informal name of a dune field on Mars located below the north pole of Mars. Its name derives from the sand dunes in Frank Herbert's novel Dune and the fictional planet Hagal. It is located at coordinates 78.0° N latitude, 84.0° E longitude, and consists of linear and round dunes with a southeast slipface orientation. It was one of the dune formations targeted for imaging by the HiRISE camera, on board the Mars Reconnaissance Orbiter, at the rate of one image every six weeks. in the third year (MY31–Mars Year 31) of its seasonal expedition. It is also known as the "Martian Morse Code" due to the linear and rounded formations of its dunes, which have the appearance of dots and dashes.

  • Hagal é o nome informal de um campo de dunas localizado abaixo do polo norte de Marte. Seu nome deriva das dunas de areia do romance de Frank Herbert Duna e o planeta fictício Hagal. Ele está localizado nas coordenadas 78.0° N de latitude, 84.0° L de longitude, e consiste de dunas lineares e redondas orientadas em direção ao sudeste. Esta foi uma das formações de dunas fotografadas pela câmera HiRISE, a bordo do Mars Reconnaissance Orbiter, a uma taxa de uma imagem a cada seis semanas, no terceiro ano (MY31–Marte Ano 31) de sua expedição sazonal. Ele também é conhecido como o "Código Morse Marciano", pois as formações de dunas lineares e arredondadas têm a aparência de pontos e traços. (pt)
