Imagine a planet with storms so powerful, they leave you in awe. That’s Jupiter, a giant planet in our solar system, showing us the incredible force of nature without any human influence. It’s a reminder of how amazing and powerful the universe can be.
One of the most advanced digital cameras ever sent into space is capturing parts of Jupiter we’ve never seen before. This camera, called JunoCam, is on a NASA spacecraft named Juno. Launched in 2011, Juno has been orbiting Jupiter since 2016. Its mission is to show us new views of Jupiter and help us feel connected to this distant planet.
Scott Bolton, the lead scientist on the Juno mission, believed it was essential to have a camera on the spacecraft. Even though the camera wasn’t needed for scientific research, it became an outreach tool to share Jupiter’s wonders with the world. However, because it wasn’t a primary science instrument, JunoCam had limited resources.
Building JunoCam was a challenge. The team had to create a camera that could survive Jupiter’s harsh environment, including its strong magnetic field and charged particles. They designed a “push frame imager,” which captures small sections of the planet at a time. The camera has a wide field of view at 58 degrees, which is unusual for space cameras.
JunoCam doesn’t take pictures all the time. Juno orbits Jupiter every 53 days, spending most of its time far from the planet. But when it gets close, it flies over Jupiter’s North and South Poles, capturing images of the storms and winds. During this brief period, JunoCam collects data, which is sent back to Earth and turned into images.
Unlike traditional space missions, JunoCam relies on the public to help process its images. People from around the world use their skills to enhance and interpret the data. This collaboration has led to exciting discoveries, like cyclones at Jupiter’s poles, which help scientists understand the planet’s atmospheric patterns.
JunoCam was initially meant to engage the public, but it has also contributed to scientific research. The images have revealed new details about Jupiter’s polar regions, which were previously unexplored. With the mission originally set to end in 2021, the success of Juno and its instruments has led to discussions about extending the mission.
Thanks to JunoCam and the public’s involvement, our understanding of Jupiter continues to grow. The mission shows how technology and teamwork can unlock the mysteries of our solar system, inspiring us to keep exploring the universe.
Use household materials to build a model of the Juno spacecraft, focusing on the JunoCam. Think about how the camera is designed to withstand Jupiter’s harsh environment. Present your model to the class, explaining the features and challenges of designing a space camera.
Conduct a simple experiment to simulate Jupiter’s storms using water, food coloring, and a rotating platform. Observe how the colors swirl and form patterns. Discuss how these patterns might be similar to Jupiter’s atmospheric conditions and what they tell us about the planet.
Download raw images from the JunoCam website and use image editing software to enhance them. Experiment with different filters and adjustments to bring out details. Share your processed images with the class and discuss what new features or patterns you discovered.
Divide into groups and research the pros and cons of extending the Juno mission. Role-play a debate where one side argues for the extension and the other against it. Consider scientific, financial, and technological perspectives. Conclude with a class vote on the decision.
Work in teams to design your own space mission to explore another planet or moon. Decide on the mission’s goals, the technology needed, and how you would involve the public. Present your mission plan to the class, highlighting how it builds on the successes of Juno and JunoCam.

Here’s this planet with incredible storms occurring. It’s awe-inspiring when you’re confronted with something completely natural, with no human influence. It gives you a sense of the power of nature.
One of the most resourceful digital cameras to ever travel beyond Earth is capturing hidden regions on Jupiter for the first time. To obtain these photos, engineers had to build a nearly indestructible camera that could survive in one of the harshest environments in our solar system. You’re looking at the closest image of the Great Red Spot ever taken, snapped by JunoCam, a small camera aboard this NASA probe. Launched in 2011, it has been orbiting Jupiter since 2016 with a special purpose: to share previously unseen regions of Jupiter and connect humanity with its celestial neighbor.
Scott Bolton, the principal investigator on Juno, was convinced that we should not fly a spacecraft to Jupiter without a camera. He enlisted help to get a camera on this spacecraft. However, since there was no need for a science investigation, JunoCam became an outreach camera. It would serve as the eyes for NASA and the world as we ventured closer to Jupiter than all previous missions. Due to its role as an outreach tool, resources were limited.
The camera was left with a constrained set of resources because the science instruments required mass, power, and volume. As a result, we could not include a large telescope. Other missions that have flown by or orbited Jupiter typically have substantial telescopes, but we knew that was out of the question. The team went to the drawing board with specific requirements for the camera. We wanted to take a picture over the poles, capture the entire pole in one image, and ensure it was in color. We also wanted to avoid murkiness, as there isn’t much sunlight at the poles.
At that time, I knew Juno would be a spinning spacecraft. Juno’s constant rotation ensures stability during the journey and guarantees that the scientific instruments aboard are in the best position to observe Jupiter. Additionally, we had to plan for the harsh environment. Jupiter has a powerful magnetic field with many charged particles that can damage electronic detectors and affect lenses. Therefore, we had to protect the camera from all of that.
At the end of the design and construction stage, the team built a camera called a push frame imager. This means only a small portion of the planet is imaged at any given moment. The field of view is quite wide at 58 degrees, which is unusual for typical spacecraft cameras. However, the camera doesn’t take pictures continuously. The spacecraft is in a 53-day orbit, spending most of its time far from Jupiter. But every 53 days, it comes in close, first flying over the North Pole, then the South Pole, skimming the cloud tops. At this closest approach, we see not only the storm but also the context and winds around the storms.
Only during this brief window does JunoCam get to work. As the spacecraft rotates, reflected sunlight from Jupiter travels through the optics, passes through color filters, and is converted into levels of gray. This data is stored onboard as a series of ones and zeros, then transmitted to Earth using radio waves, where it is reconstructed into an image.
We do not have a classic imaging science team; we rely on the public to be our virtual imaging team. Citizens from around the world help process the images that JunoCam captures. We have experts who work with raw data and others who might use software to adjust color balance or enhance the images. The possibilities are as limitless as people’s imaginations.
While the camera was originally intended to boost public engagement, it turns out we can conduct interesting science with our outreach camera. No spacecraft had ever imaged the polar regions, as most stay in the equatorial zone. The first discovery was that there are cyclones around the poles. We are studying atmospheric circulation, and these structures are very stable, teaching us about circulation patterns and their connection to lower latitudes.
Gradually, the data is being analyzed scientifically, and papers are being written. When viewed through a telescope, Jupiter appears pastel and subtle in color. With the public’s help, JunoCam images have transformed our understanding of what Jupiter looks like. Artists can take these images and create vibrant representations, revealing deep blues and dark browns.
Currently, our mission is scheduled to conclude around 2021, but since all instruments are performing well and the spacecraft is thriving in Jupiter’s radiation environment, we are exploring ways to extend the mission. There is no end in sight for now.
