The European Space Agency (ESA) is set to launch the Jupiter Icy moons Explorer (JUICE) spacecraft on April 13 from the European spaceport in Kourou, French Guiana. The mission will explore three of Jupiter’s moons, Ganymede, Callisto, and Europa, in an attempt to uncover whether they could support life.
Jupiter’s Icy Moons: First observed over 400 years ago
More than four centuries ago, Galileo Galilei first observed Ganymede, Callisto, and Europa, three moons orbiting Jupiter. In 1995, NASA’s Galileo spacecraft revealed the existence of liquid oceans beneath the icy crust of these moons, containing a vital ingredient for life on Earth – liquid water. This remarkable discovery, which identified the presence of liquid water so far away from Earth, has led scientists to explore the possibility of life existing on these moons.
A Mission to investigate the Icy Moons of Jupiter
The JUICE spacecraft will take approximately eight years to travel out to Jupiter, with an estimated arrival date in 2031. JUICE will investigate whether the necessary ingredients for life to form – liquid water, heat, and organic material – exist on these moons.
The mission of JUICE
It’s mission is offering scientists a remarkable chance to unravel the enigmas of the icy moons of Jupiter by exploring them in great detail. It is the maiden mission of its kind to study these three moons and provide a decisive answer as to whether or not life could thrive on them. The mission will investigate the composition of the moons, their geology, and their magnetic and gravitational fields.
The possibility of life on Jupiter’s Moons
“We’re almost certain that at least three of the moons have good liquid water oceans underneath the surface. If we are looking for places in our solar system, where life can form, the first ingredient you’re looking for is liquid water,” says Professor Dougherty. If the necessary ingredients for life are stable enough over a long enough period of time, then life may potentially form.
Answering questions about life beyond Earth
According to Caroline Harper, who is the Head of Space Science at the UK Space Agency, the JUICE mission is expected to provide insights into the possibility of finding life in systems with a gas giant like Jupiter and moons orbiting in other parts of the galaxy.
Exploring the Icy Moons in detail
JUICE will explore Ganymede, Callisto, and Europa in detail, including their interiors, subsurfaces, surfaces, and exospheres. The spacecraft will use a suite of scientific instruments to study the moons, including cameras, spectrometers, and radar.
The importance of liquid water
Liquid water is a key ingredient for life on Earth, and its presence on these moons raises the possibility that life could exist beyond our planet. If JUICE finds that the necessary ingredients for life are stable enough over a long enough period of time, then it could provide evidence that life exists elsewhere in our solar system.
The potential for future missions
It will provide a wealth of information about Jupiter’s moons, which could inform future missions to these or other celestial bodies. The mission could also inspire new missions to explore the potential for life beyond our planet.
The JUICE mission is an important step in our search for life beyond Earth. By exploring the icy moons of Jupiter, scientists hope to uncover the secrets of these celestial bodies and answer the question of whether life could exist on them. With its suite of scientific instruments, JUICE will provide a wealth of information about the composition, geology, and potential for life on these moons.
Jupiter’s Icy Moons: A unique opportunity for exploration
Jupiter is the largest planet in our solar system, and it has over 90 moons. However, Ganymede, Callisto, and Europa are of particular interest to scientists due to the evidence of liquid water underneath their icy surfaces. These moons are also believed to have a geologic activity that could generate energy, such as tides and volcanoes.
The JUICE mission will provide scientists with a unique opportunity to explore these moons in detail. By studying their composition, geology, and magnetic and gravitational fields, scientists hope to gain a better understanding of the potential for life beyond our planet.
JUICE’s scientific instruments
JUICE will carry a suite of scientific instruments to study the moons of Jupiter. These instruments include cameras, spectrometers, and radar. They will be used to study the moons’ interiors, subsurfaces, surfaces, and exospheres.
The spacecraft will also carry a magnetometer, which will measure the magnetic fields around the moons. This will help scientists understand the moons’ interiors and the processes that generate the magnetic fields.

The Ultraviolet Spectrograph (UVS) will study the moons’ exospheres, which are the thin atmospheres that surround them. The UVS will be used to study the composition and dynamics of the exospheres.
The mission will also carry a laser altimeter, which will be used to map the surface of the moons. This will help scientists understand the geology and history of the moons.
