Juno ready for launch in 2011.

The Juno spacecraft is a special robot explorer from NASA that is currently orbiting the giant planet Jupiter. It was built by Lockheed Martin and is managed by NASA's Jet Propulsion Laboratory. Juno launched from Cape Canaveral Air Force Station on August 5, 2011. It arrived at Jupiter and entered a unique polar orbit on July 5, 2016. This mission is part of the New Frontiers program, which sends probes to explore different parts of our Solar System.

Juno was originally planned to end its mission by diving into Jupiter's atmosphere. However, its mission has been extended multiple times. It continues to orbit Jupiter, studying the planet and its inner moons like Thebe, Amalthea, Adrastea, and Metis, and even Jupiter's rings.

The main goals of Juno are to learn about Jupiter's ingredients, its powerful gravity, its strong magnetic field, and the amazing auroras at its poles. Scientists also hope to find out how Jupiter first formed. They want to know if it has a solid core, how much water is deep inside its atmosphere, and how its super-fast winds, which can blow at speeds up to 620 km/h (390 mph), work.

Juno is only the second spacecraft ever to orbit Jupiter. The first was the Galileo orbiter, which explored Jupiter from 1995 to 2003. Unlike many other spacecraft that travel far from the Sun and use special nuclear power sources, Juno uses large solar panels for energy. When it launched, Juno had the three largest solar panel wings ever used on a planetary probe! These panels are super important for keeping the spacecraft stable and powered up.

As of early 2026, Juno is still working well and sending information back to Earth through the NASA Deep Space Network.

How Juno Got Its Name

Juno is named after a goddess from ancient Greek and Roman stories. In these myths, the god Jupiter (who the planet is named after) would often hide behind clouds when he was up to something mischievous. His wife, the goddess Juno, had a special power: she could look through the clouds and see Jupiter's true actions.

This name fits the mission perfectly, as the Juno spacecraft is designed to look through Jupiter's thick clouds to discover its secrets!

Sometimes, people mistakenly think "Juno" is an acronym for "Jupiter Near-polar Orbiter." But the mission team confirms it's truly named after the Roman goddess. It's also known as "New Frontiers 2" because it's the second mission in NASA's New Frontiers program.

Juno Mission Journey

Juno · Earth · Mars · Jupiter

NASA chose Juno on June 9, 2005, as the next big mission after the New Horizons spacecraft. Scientists had wanted to send a probe to Jupiter for a long time.

Juno took five years to travel to Jupiter, finally arriving on July 5, 2016. The spacecraft journeyed about 2.8×10^⁹ km (19 AU; 1.7×10^⁹ mi) to reach Jupiter. It was originally designed to orbit Jupiter 37 times.

Juno used a clever trick called a gravity assist to speed up its journey. This happened during an Earth flyby in October 2013. This boost helped Juno slingshot itself towards Jupiter. Once it reached Jupiter, the spacecraft fired its engine to slow down and enter a polar orbit.

Initially, Juno was supposed to move into a shorter 14-day orbit. However, because of a small problem with its main engine, it stayed in its longer 53-day orbit. This allowed Juno to continue its mission for much longer than planned! The extended mission included close flybys of Jupiter's large moons, Ganymede, Europa, and Io. These flybys helped to change Juno's orbit, making it shorter over time.

During its mission, Juno uses special instruments to measure heat coming from deep inside Jupiter's atmosphere. These measurements help scientists understand how much water is there, which gives clues about how Jupiter formed. Juno also studies Jupiter's powerful winds and its magnetic field. The mission was extended multiple times and is now planned to continue through September 2025 and beyond.

Launching Juno into Space

Juno awaiting its launch in 2011.

Juno launched on an Atlas V rocket from Cape Canaveral Space Force Station in Florida on August 5, 2011. The powerful rocket used a main engine and five smaller solid rocket boosters to push Juno into space.

After the boosters burned out, they fell away. Then, a protective cover called a payload fairing separated, revealing Juno. The rocket's second stage then fired twice. This second burn was strong enough to send Juno out of Earth's orbit and on its way to Jupiter.

Before separating from the rocket, Juno was spun like a top. This spin helped keep the spacecraft stable during its long journey. Once it separated, Juno unfolded its huge solar panels, which began to charge its batteries. The solar panels also helped slow down the spacecraft's spin.

The trip to Jupiter took five years. It included two engine firings in 2012 and a flyby of the Earth in 2013. By the time it reached Jupiter, Juno had traveled about 19 astronomical units (2.8 billion kilometres).

Earth Flyby and Gravity Assist

After about a year of flying in an elliptical path around the Sun, Juno fired its engine twice. These "deep space maneuvers" changed its path so it could swing by Earth in October 2013.

This close pass by Earth was a crucial gravity assist maneuver. It used Earth's gravity to give Juno a huge speed boost, adding more than 3.9 km/s (8,700 mph) to its speed. This put Juno on the right course for Jupiter. The Earth flyby was also a practice run for the Juno team to test instruments and procedures before reaching Jupiter.

Entering Jupiter's Orbit

Jupiter's immense gravity pulled the approaching spacecraft, speeding it up to about 210,000 km/h (130,000 mph). On July 5, 2016, Juno fired its engine for 2,102 seconds. This "insertion burn" slowed the spacecraft by 542 m/s (1,780 ft/s). This change was just enough to switch its path from a flyby to an elliptical, polar orbit around Jupiter. Juno successfully entered Jupiter's orbit on July 5, 2016.

Juno's Orbit and Environment

Juno's elliptical orbit and Jupiter's radiation belts.

Juno's orbit is very stretched out, taking it as close as 4,200 km (2,600 mi) to Jupiter and as far as 8.1×10^⁶ km (5.0×10^⁶ mi) away. This path helps Juno avoid Jupiter's intense radiation belts as much as possible. These radiation belts can damage spacecraft electronics and solar panels.

The mission team carefully planned Juno's path to pass through areas with less radiation. The spacecraft also has a special "Juno Radiation Vault," with 1-centimeter-thick titanium walls. This vault protects Juno's sensitive electronics by blocking most of the radiation. Even with this protection, the radiation is very strong.

Originally, Juno was expected to complete 37 orbits. However, due to the engine issue mentioned earlier, it remained in its 53-day orbit. NASA extended the mission multiple times, first through July 2021, and then through September 2025. All of Juno's instruments are still working well.

Juno completed its first close pass by Jupiter (called perijove 1) on August 26, 2016. During this pass, it captured the first-ever images of Jupiter's north pole.

On October 14, 2016, Juno entered "safe mode" because its computer detected something unexpected. In safe mode, the spacecraft turns off non-essential systems and points itself towards the Sun to gather power. Because of this, no science data was collected during its second close approach.

However, Juno quickly recovered. By December 11, 2016, it completed perijove 3 with almost all instruments working. The mission continued to collect valuable data with each close pass.

In June 2018, NASA extended Juno's mission through July 2021. Then, in January 2021, the mission was extended again to September 2025. During these extended phases, Juno began to study Jupiter's largest moons.

A flyby of Ganymede happened on June 7, 2021. Juno came within 1,038 km (645 mi) of the moon's surface, the closest any spacecraft had been since 2000.
A flyby of Europa took place on September 29, 2022, at a distance of 352 km (219 mi).
Juno performed two close flybys of Io on December 30, 2023, and February 3, 2024. These flybys gathered important data on Io's volcanic activity.
From April 2024, Juno began a new series of experiments to learn more about Jupiter's inner structure.

Mission End and Planetary Protection

NASA originally planned for Juno to dive into Jupiter's atmosphere and burn up after completing its mission. This controlled end was designed to prevent any chance of the spacecraft accidentally crashing into one of Jupiter's moons, especially Europa. Scientists want to protect these moons from any possible contamination by tiny Earth microbes that might still be on the spacecraft. This is part of NASA's planetary protection rules.

However, due to the mission's success, Juno's mission has been extended multiple times and is currently operating beyond its second extension, which ended in September 2025.

The Juno Team

Scott Bolton from the Southwest Research Institute is the lead scientist for the Juno mission. He is in charge of all parts of the mission. The Jet Propulsion Laboratory in California manages the mission, and Lockheed Martin Corporation built the spacecraft. Many other scientists and institutions also help with the mission.

Mission Cost

The Juno mission was estimated to cost about US$1.46 billion for its operations and data analysis through 2022.

What Juno Aims to Discover

Jupiter imaged using the VISIR instrument on the Very Large Telescope, 2016. These observations helped to plan Juno's mission.

Juno's science instruments are designed to:

Figure out how much water is in Jupiter's atmosphere. This helps scientists understand how Jupiter and the Solar System formed.
Get a better idea of the mass of Jupiter's core. This also helps with understanding its formation.
Create detailed maps of Jupiter's gravitational field to learn about the planet's interior structure.
Map Jupiter's magnetic field to understand where it comes from and how deep inside the planet it is created.
Study the changes in Jupiter's atmosphere, including its temperature, clouds, and winds, at different depths and latitudes.
Explore the amazing three-dimensional structure of Jupiter's polar magnetosphere and auroras.
Measure tiny changes in Jupiter's orbit caused by its rotation, which can help test general relativity theories.

Juno's Scientific Instruments

Juno carries nine special instruments to achieve its science goals:

Microwave Radiometer (MWR)

Microwave Radiometer

The Microwave Radiometer has six antennas that measure electromagnetic waves in the microwave range. These are the only waves that can pass through Jupiter's thick atmosphere. The radiometer measures how much water and ammonia are in the deep layers of the atmosphere, up to 500–600 km (310–370 mi) deep. This helps scientists understand how deep the atmospheric circulation goes.

Jovian Infrared Auroral Mapper (JIRAM)

Jovian Infrared Auroral Mapper

The JIRAM instrument looks at the upper layers of Jupiter's atmosphere using near infrared light. It takes pictures of Jupiter's auroras and measures the heat coming from the atmosphere. This helps determine how clouds with water move beneath the surface. JIRAM can also detect gases like methane, water vapor, ammonia, and phosphine.

Magnetometer (MAG)

Magnetometer

The magnetometer helps map Jupiter's magnetic field. It measures the strength and direction of the magnetic field lines. This helps scientists understand how Jupiter's magnetic field is created deep inside the planet and the structure of its polar magnetosphere.

Gravity Science (GS)

Gravity Science

This experiment measures Jupiter's gravity using radio waves. As Juno orbits close to Jupiter, tiny changes in gravity cause small changes in the spacecraft's speed. By detecting these changes in the radio signals sent back to Earth (called the Doppler effect), scientists can create a map of how mass is distributed inside Jupiter.

Jovian Auroral Distributions Experiment (JADE)

JADE

JADE is a detector that measures low-energy ions and electrons in Jupiter's auroras. It helps scientists understand the particles that create these amazing light shows at Jupiter's poles.

Jovian Energetic Particle Detector Instrument (JEDI)

JEDI

JEDI is another detector that measures high-energy ions and electrons in Jupiter's polar magnetosphere. It helps study particles like hydrogen, helium, oxygen, and sulfur that are found in this region.

Radio and Plasma Wave Sensor (Waves)

Radio and Plasma Wave Sensor

This instrument listens to radio and plasma waves in Jupiter's auroral region. It helps identify the currents that cause Jupiter's radio emissions and accelerate auroral particles. It also observes how Jupiter's atmosphere and magnetosphere interact.

Ultraviolet Spectrograph (UVS)

Ultraviolet Spectrograph

UVS records ultraviolet light from Jupiter's polar magnetosphere. It provides spectral images of the UV auroral emissions, giving scientists more information about these powerful light displays.

JunoCam (JCM)

JunoCam

JunoCam is a visible light camera and telescope. It was originally included to help with education and public outreach, allowing people to see Jupiter up close. It was later used to study the movement of Jupiter's clouds, especially at the poles. Despite radiation damage, JunoCam has been repaired through a process called annealing and continues to operate as of July 2025.

How Juno Works

Satellite Body

Juno's main body, which holds its electronics and propulsion system, is shaped like a six-sided prism.

Solar Panels

Juno is the first mission to Jupiter to use solar panels for power. Previous missions to the outer Solar System used nuclear power sources. Juno's solar panels are very important because they are the farthest solar-powered trip in space exploration history. Even though Juno receives only 4% of the sunlight it would get at Earth, advances in solar cell technology made it possible to use large solar panels.

The spacecraft has three large solar panels arranged around it. Two panels have four sections each, and the third has three sections plus a magnetometer. Each panel is 2.7 by 8.9 m (8 ft 10 in by 29 ft 2 in), giving a total of 50 square metres (540 sq ft) of active solar cells. These were the largest on any NASA deep-space probe when Juno launched.

The three panels together weigh almost 340 kg (750 lb). At Jupiter, they generate about 435 watts of power, which is enough to run the spacecraft. The solar panels stay in sunlight almost all the time, except for brief moments when the main engine fires or when Jupiter blocks the Sun. Two large lithium-ion batteries store power for when Juno passes through Jupiter's shadow.

Communication with Earth

Juno's high-gain antenna dish being installed.

Juno communicates with Earth using the large antennas of the NASA Deep Space Network (DSN). It sends data directly using X-band radio waves. The spacecraft's computer can send about 50 megabits of instrument data per second.

Because of the vast distance, Juno can only send back about 40 megabytes of JunoCam data during each 11-day orbit. This limits the number of images that can be sent. However, much more data is sent for the other scientific instruments. JunoCam is mainly for public engagement, so its data is secondary to the science data.

The communication system is also used for the Gravity Science experiment.

Propulsion System

Juno uses a main engine called LEROS 1b, which uses special fuels called hypergolic propellant. It carries about 2,000 kg (4,400 lb) of fuel. The main engine provides a thrust of 645 newtons and is used for major maneuvers, like entering Jupiter's orbit.

For steering and making small adjustments to its path, Juno has twelve smaller thrusters. These thrusters help control the spacecraft's orientation in space.

Galileo Plaque and Minifigures

Galileo Galilei plaque.

Juno carries a special plaque dedicated to Galileo Galilei, a famous scientist. The plaque was provided by the Italian Space Agency and is made of aluminum. It shows a picture of Galileo and a text he wrote in 1610. In this text, Galileo described his observations of what we now know are Jupiter's largest moons.

The spacecraft also carries three special Lego minifigures! These figures represent Galileo Galilei, the Roman god Jupiter, and his wife, the goddess Juno. In mythology, Jupiter would hide behind clouds, and Juno could see through them. The Juno minifigure holds a magnifying glass, and Jupiter holds a lightning bolt. Galileo has his telescope. These figures were made of aluminum to survive space and are part of a program to inspire kids in science, technology, engineering, and mathematics (STEM).

Amazing Scientific Discoveries

Juno has already made many exciting discoveries that are changing what we know about Jupiter.

It gathered new information about Jupiter's lightning, which changed earlier theories.
Juno provided the first-ever views of Jupiter's north pole.
It gave scientists new insights into Jupiter's auroras, magnetic field, and atmosphere.
In 2021, Juno helped scientists discover that the dust causing the Zodiacal light (a faint glow in the night sky) comes from Mars, not from comets or asteroids as previously thought.
Juno found clusters of stable cyclones at Jupiter's poles.
It discovered that Jupiter's magnetosphere is uneven and chaotic.
Using its Microwave Radiometer, Juno found that Jupiter's famous red and white bands extend hundreds of kilometers deep into the atmosphere.
Juno's findings suggest that Jupiter might not have a solid core. Instead, it might have a "fuzzy" core made of rock pieces and metallic hydrogen. This unusual core might be the result of a collision that happened when Jupiter was forming.
In April 2020, Juno detected a meteor impact on Jupiter.
Juno's data shows that Jupiter's storms are much taller than expected. Some extend 100 kilometers (60 miles) below the cloud tops, and the Great Red Spot extends over 350 kilometers (200 miles) deep.
