After completing a major software update in April, NASA’s Curiosity Mars rover took a last look at “Marker Band Valley” before leaving it behind,
“Anyone who’s been to a national park knows the scene looks different in the morning than it does in the afternoon,” said Curiosity engineer Doug Ellison of NASA’s Jet Propulsion Laboratory in Southern California, who planned and processed the images. “Capturing two times of day provides dark shadows because the lighting is coming in from the left and the right, like you might have on a stage – but instead of stage lights, we’re relying on the Sun.
Adding to the depth of the shadows is the fact that it was winter – a period of lower airborne dust – at Curiosity’s location when the images were taken. “Mars’ shadows get sharper and deeper when there’s low dust and softer when there’s lots of dust,” Ellison added. The image peers past the rear of the rover, providing a glimpse of its three antennas and nuclear power source. The Radiation Assessment Detector, or RAD, instrument, which appears as a white circle in the lower right of the image, has been helping scientists learn how to Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington.
