ALT A promotional image for the 'Europa Kids Art Challenge' featuring a cosmic background filled with deep purples and oranges, resembling a nebula. In the foreground, there is an artistic representation of Jupiter's moon Europa, with a cracked and textured surface. A space probe with solar panels is positioned near the bottom right, suggesting exploration. The text 'Europa Kids Art Challenge' is written in bold, white letters, standing out against the colorful space backdrop. A smaller depiction of Jupiter is partially visible in the top right corner.

ALT A child's drawing showing the interior ocean of Europa populated with a large pink octopus, jellyfish, and a robotic probe in the water. Above the ocean is a cutaway view of Europa's icy crust with erupting geysers. Jupiter and a starry black sky are visible beyond.

ALT A group of 11 people dressed in winter clothes are jumping in front of a large gondola with a telescope and solar panels in Antarctica.

ALT An artist's rendering shows the NISAR satellite in Earth orbit. The long, gold-covered body is toward the bottom of the frame and it has its solar arrays extended out from each side. A long boom stretches out and shows the deployed circular reflector high above the spacecraft.

ALT A woman kneels down in the snow, wearing snowshoes and a bright orange jacket. She is looking down at a scientific instrument in her hands.

ALT A man wearing a black leather jacket and brown shirt takes a selfie in front of a light blue glacier. Between the man and the glacier is a small area of patchy grass. A second person in the background is walking toward the glacier.

ALT A woman sits on a wooden boat with her legs stretched out toward the camera. She is smiling and wearing a bright orange life vest. In the background is a light blue body of water. A blanket of white clouds cover most of the blue sky.

ALT A woman sits on a tan-gray rock to the right of the image. She is wearing a deep purple colored shirt and black pants. One of her legs is tucked up while the other hangs off the side of the rock, and her arms are gently crossed. The woman is at a higher elevation than the background, so the landscape behind her can be seen a far distance. The landscape to the left of the image is a nearly flat ground in dark green, brown, and orange colors, and centered in the image is a lake which is reflecting the color of the sky off of it. Above the horizon, the sky is a bright blue color, but is covered slightly by sparse gray clouds.

ALT An image from inside the Europa Clipper clean room at NASA's JPL. The room has very tall ceilings and everything is white from the floor to the ceiling. About 10 engineers and scientists, dressed in head-to-toe white protective gear, are gathered around the Europa Clipper spacecraft in the center of the room working on the spacecraft and helping to maneuver it across the floor to a new location. Above them is a glass encased gallery area where a crowd of people are watching them work.

ALT In this cartoonish illustration, the DART spacecraft at the top of the image approaches one large and one small meteor in the upper right. On the bottom of the image, a small robotic rover is on a blue-grey lunar surface. On the left, the Psyche spacecraft shines a laser toward Earth. An inset on the left shows a cat resting on a couch while looking at a laser dot on the couch. On the lower right, the NISAR spacecraft orbits above Earth. The Greek letter π appears in the center of the image next to the words NASA Pi Day Challenge. An arrow curves upward from the end of the text and points to the word answers. There are lines indicating hints about how to solve the problems in the challenge.

ALT In this animation, still Earth is shown from space with lines marking where the NISAR spacecraft has mapped the surface. A gradient color bar in the lower left indicates biomass quantities shown in the NISAR measurements. A counter in the upper right displays Day: 01 and Orbit: 012.
