Ingenuity Helicopter Captures Image of Perseverance Rover

This image shows the South Séítah region of Jezero Crater, captured by NASA’s Ingenuity helicopter during its 11th flight on August 4, 2021. At the bottom center of the image is Ingenuity’s shadow. Above it, toward the top of the frame -- just beyond the dune field and right of center -- is the Perseverance rover (white circle). Image credit: NASA / JPL-Caltech.

Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere layer corresponds to temperatures, from hot to cold, in this order: white, yellow, bright red and lastly, dark red. The aurorae are the hottest regions and the image shows how heat may be carried by winds away from the aurora and cause planet-wide heating. Image credit: J.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.
