JunoCam is the “citizen science” camera on board Juno. As the spacecraft orbits Jupiter, JunoCam snaps pictures of the planet from different angles and radial distances, targeting features identified in part through the collaborative efforts of the amateur astronomer community.
JunoCam’s imagery is sent back to Earth and posted to the Mission Juno website, where the general public may download them for subsequent image processing. The images processed by these citizen scientists are returned to the Mission Juno website and range from detailed scientific imagery and analyses to beautiful works of space-themed art.
How do you take a picture when your spacecraft is spinning? Malin Space Science Systems (MSSS) took on this challenge for the Juno project. JunoCam has a “push-frame” design, like many MSSS cameras, that acquires the image a strip at a time as the spacecraft spins and the earth passes through the field of view.
The camera has 4 filters: red, green, blue and near-infrared. We get red, green and blue strips on one spacecraft rotation (the spacecraft rotation rate is 2 revolutions per minute, or 2 rpm), and the near-infrared strips on the second rotation.
To get the final image product the strips must be stitched together and the colors lined up. Come back on October 10th and you can see each step of the process here in our image gallery.
We’re calling all amateur astronomers to upload their telescopic images and data of Jupiter. These uploads are critical for providing context for new JunoCam images and will help NASA successfully plan the future of the mission.
If you’re a veteran astrophotographer or if you’re just getting started with your first telescope, we highly recommend you read our Submission Guidelines before submitting data. In the PDF you’ll find information about the best capture and process workflows as well as links to free software and tutorials.

Hurricanes Laura and Delta dealt a double blow to Louisiana just six weeks apart.
Real-World Testing We loved the last Stumpjumper, but we wanted to make it an even more capable descender—this meant adding stiffness to the frame. To do it, we developed our own mountain-specific stiffness test that examined the connection between a rider’s hands and feet. When each get different signals, you ...
