NASA's Europa Clipper, en route to the Jupiter system to investigate the icy moon Europa, conducted a critical test of its radar instrument during a flyby of Mars on March 1, 2025. During the testing, the instrument received echoes of its very-high-frequency radar signals that engineers processed to develop this image, called a radargram. The image was made using radar signals that bounced off Mars. What looks like a skyline is the outline of the topography. Features seen in the radargram include contributions from the topographic features both along and near the ground track (the path below …
