The High Resolution Imaging Experiment, known as HIRISE is a big and powerful HIRISE camera that takes pictures that cover vast areas of Martian terrain while being able to see features as small as a kitchen table.
HiRISE also makes observations at near-infrared wavelengths to obtain information on the mineral groups present.
Attached to NASA’s Mars Reconnaissance Orbiter, the HIRISE recently captured a brilliant view of a Martian crater. Taken by the end of 2021 but released on Jan. 20, reveals a crater overfilled with dazzling dunes.
The impressive discovery fits an important goal for planetary scientists, marking the location of zero longitude on Mars – the line that separates the western and eastern hemispheres on the red planet.
