For centuries, we’ve known about Jupiter’s moons, and for decades, we’ve been capturing images of them. Now, two exciting new missions are set to explore these icy moons more closely than ever before. These missions aim to answer one of the biggest questions in astronomy: Could there be life beyond Earth?
Jupiter has always been a bright spot in our night sky, but it wasn’t until 1879 that people began to see it as more than just a distant light. Thanks to Irish astronomer Agnes Mary Clerke, we learned that Jupiter is a complex planet with many secrets. Over the years, missions like Pioneer 10, Voyager, Hubble, Galileo, and Juno have helped us understand Jupiter’s place in our Solar System. Even the James Webb Space Telescope has given us new insights with its advanced cameras.
Jupiter is a wild place with temperatures dropping to the negative 200s, ammonia rain, and winds reaching 400 miles per hour. It’s not a place where we expect to find life, but scientists are curious about its moons. They have built two spacecraft to explore these moons up close. The first mission, called JUICE (Jupiter Icy Moons Explorer), is one of the most ambitious projects by the European Space Agency.
JUICE will focus on Jupiter and its three icy moons: Europa, Callisto, and Ganymede. These moons are believed to be rich in water, with possible oceans beneath their icy surfaces. Scientists are eager to study not only the water but also the energy sources that might support life.
We used to think life needed sunlight to exist, but we’ve discovered creatures living in extreme conditions on Earth, like deep-sea vents. These creatures don’t rely on sunlight but on other energy sources. Scientists believe that similar energy could come from the gravitational pull of Jupiter on its moons, creating tides and possibly supporting life in their hidden oceans.
One of JUICE’s main goals is to explore the conditions on Europa and Ganymede to see if there’s enough water and energy for life. JUICE is equipped with 10 powerful scientific instruments to study Jupiter and its moons in various ways. These include telescopes, sensors, and a special radar called RIME (Radar for Icy Moon Exploration) to look for water beneath the ice.
RIME will send radio waves into the moons’ ice and analyze the echoes to find liquid water. It’s a delicate instrument, but it has been tested to withstand the harsh conditions of space. JUICE will also use the gravity of Venus and Earth to help it reach Jupiter by 2031.
Once at Jupiter, JUICE will face challenges like intense radiation and limited solar energy. After a year, it will fly by Europa, where NASA’s Europa Clipper will also be exploring. Europa is thought to have a massive ocean beneath its icy surface, and Clipper will use its instruments to study it closely.
After exploring Europa, JUICE will head to Callisto, a moon with a deep ocean and a heavily cratered surface. It will then move on to Ganymede, the largest moon in the Solar System, even bigger than Mercury. JUICE will orbit Ganymede, a first for any spacecraft, to study its surface and subsurface ocean.
After four years of exploration, JUICE will end its mission with a controlled crash into Ganymede, ensuring no contamination of potential water sources. This mission will leave a lasting impact on our understanding of Jupiter, its moons, and the possibility of life beyond Earth. With the help of the James Webb Space Telescope, Europa Clipper, and JUICE, our knowledge of the Solar System is set to expand once again.
Using materials like clay or papier-mâché, create a model of Jupiter and its three icy moons: Europa, Callisto, and Ganymede. Pay attention to the size and distance scale. This will help you visualize the relationship between Jupiter and its moons and understand the challenges of exploring them.
Research the extreme weather conditions on Jupiter, such as ammonia rain and high-speed winds. Create a presentation or a short video demonstrating these conditions. You can use props or digital tools to simulate the weather, helping you grasp the harsh environment that spacecraft like JUICE must endure.
Investigate how life exists in extreme environments on Earth, such as deep-sea vents. Write a report or create a poster that compares these Earth environments to the potential conditions on Jupiter’s moons. This will help you understand how life might survive without sunlight, using other energy sources.
Imagine you are an engineer tasked with designing a spacecraft to explore Jupiter’s moons. Sketch or build a model of your spacecraft, considering the instruments it would need, like RIME, to study the moons’ icy surfaces and potential oceans. This activity will enhance your understanding of the technology used in space exploration.
Follow the progress of the JUICE mission from launch to its arrival at Jupiter. Create a timeline or a journal documenting key milestones and discoveries. This ongoing project will keep you engaged with real-time space exploration and deepen your appreciation for the mission’s goals and challenges.

[Music] We’ve known about Jupiter’s moons for centuries. We’ve been photographing them for decades, and beginning today, a new pair of missions will be launched to bring us closer than ever to Jupiter’s icy moons. There are many mysteries surrounding them, and we have lots of questions with very few answers. This mission aims to address what may be the biggest question in astronomy: Do the conditions for life exist beyond Earth?
[Music] Jupiter has always been visible in our night sky, but it wasn’t until 1879 when Irish astronomer Agnes Mary Clerke published an image that people could truly appreciate that Jupiter was more than just a bright light above the horizon. It is a complex, stormy planet with secrets to be revealed. Bigger telescopes and better probes have introduced us to Jupiter’s place in orbit, starting with Pioneer 10, then Voyager, and later Hubble, Galileo, and Juno. Even the James Webb Space Telescope, using its near-infrared camera, has provided us with a new way to experience the planet.
[Music] We understand that Jupiter is a wild place; temperatures hover in the low negative 200s, it rains ammonia, and persistent winds can top 400 miles per hour. This is not a place likely to harbor the conditions for life as we know it, but scientists have wondered whether Jupiter’s moons could. They have built a pair of spacecraft that will allow them to observe these moons up close. After more than a decade of planning, the first of the two new missions toward Jupiter is ready for space. It’s called JUICE, the Jupiter Icy Moons Explorer, and it is one of the most ambitious missions ever attempted by the European Space Agency.
[Music] JUICE will target four of the most intriguing celestial bodies in the Solar System: Jupiter and its three ice-covered moons, Europa, Callisto, and Ganymede. These moons, formed at a distance from Jupiter and beyond, are often very water-rich. There could be oceans inside Europa, Ganymede, and Callisto. Scientists are eager to study not just the water beneath the moons’ frozen surfaces but also their sources of energy.
We used to think that life could only exist in the presence of sunlight, but scientists have discovered creatures living in the dark under extreme temperatures and pressure alongside vents spewing toxic substances at the bottom of Earth’s oceans. Now we know that life doesn’t need photosynthesis; it just needs an energy source. Scientists believe that energy could come from tides formed inside these moons by the intense gravitational pull of Jupiter, similar to how our moon influences the tides on Earth. This opens up new possibilities for ice-covered oceans inside these bodies to harbor life.
One of the main objectives for JUICE is to search for the environmental conditions on the ocean worlds of Europa and Ganymede to discover whether there is enough water and energy below their icy surfaces. The mission will rely on one of the most powerful suites of instruments ever sent to the Jupiter system, with a total of 10 scientific instruments on JUICE.
[Music] These instruments will observe Jupiter and its moons in all possible wavelengths. We have telescopes for various wavelengths, a radiometer to analyze the atmosphere and wind structures, and electric and magnetic sensors. Some instruments will be deployed at the tip of a magnetometer boom in space, and we also have particle packages to analyze the plasma environment of Jupiter and Europa.
These 10 instruments will provide new insights into the Jupiter system, which some see as a mini solar system unto itself. One key technology JUICE will use to search for water is an instrument known as RIME, the Radar for Icy Moon Exploration.
[Music] RIME is designed to penetrate deep below the surface of the moons. The objective is to locate the liquid water ocean beneath the icy crust by directing radio waves at the moons’ ice sheets and analyzing their echoes. RIME will help determine the depth at which liquid water might reside.
Stretching 16 meters across, RIME may look delicate, but it underwent extensive testing to simulate the conditions it will face on its journey to Jupiter. After surviving the intense cold of space, JUICE will also experience extreme heat as it passes into Venus’s orbit for a slingshot maneuver close to the Sun. To prepare for this, powerful lamps simulate the heat of the Sun while the spacecraft passes through Venus.
After surviving the heat, JUICE will engage in two more Earth flybys before finally reaching Jupiter’s orbit in 2031. Once there, JUICE will face extreme conditions, including Jupiter’s radiation, which can affect electronics. The spacecraft has been designed to withstand these stresses for several years. Additionally, solar energy will be limited around Jupiter, so JUICE’s solar panels must be large to capture enough sunlight.
After a year in Jupiter’s orbit, JUICE will make its first of two flybys of Europa in 2032, alongside NASA’s Europa Clipper, which will launch in 2024. Clipper will focus mostly on Europa, where scientists believe one of the best places for life could exist in the Solar System. The liquid water ocean on Europa is thought to be more massive than Earth’s ocean, despite Europa’s smaller size. The grooves on Europa’s surface suggest that tidal energy has been strong enough to crack its surface.
Europa Clipper will arrive at the moon with its own suite of instruments, including thermal cameras, spectrometers, ice-penetrating radar, and a dust analyzer to detect materials ejected into space. Recent findings suggest there might be plumes of water vapor coming from Europa’s surface. Clipper will fly at low altitudes, potentially passing through a plume if it is in the right location.
After working together to explore Europa, the two probes will go their separate ways. Clipper will continue its nearly 50 flybys of Europa, while JUICE will change course for Callisto, Jupiter’s second-largest moon. Callisto is believed to harbor an ocean more than 150 miles below its surface, and its heavily cratered surface indicates it has experienced little geological activity.
[Music] JUICE will fly by Callisto more than 20 times to investigate the moon and adjust its trajectory for its final destination, Ganymede. This mission is significant because no spacecraft has ever orbited another planet’s moon before. JUICE will be in orbit around Ganymede, allowing for uniform coverage of the moon’s surface.
Ganymede is the largest moon in the Solar System, even larger than Mercury. Its surface features intrigue scientists, with sprawling grooves and a mix of cratered and less active regions. Exploring Ganymede’s surface will provide insights into its evolution and the dynamics of its subsurface ocean, which could potentially harbor life.
Finally, after more than four years exploring Jupiter and its icy moons, the JUICE mission will conclude with a dramatic maneuver: an intentional crash landing into Ganymede’s surface, executed carefully to avoid contaminating any near-surface water resources. The mission will end, but JUICE’s impact will resonate for years to come.
[Music] By studying the Jupiter system, we will learn something new about the planet and our Solar System. With the James Webb Space Telescope, Europa Clipper, and the JUICE mission, we can expect our understanding of Jupiter, its moons, and the potential for life beyond Earth to be revolutionized once again.
