Juice mission to make flyby of the moon and Earth
On August 19 and 20, 2024, the JUICE spacecraft will sweep close to the moon and Earth system, coming as shut as it may to each worlds earlier than slingshotting out into area once more with an altered velocity and path. These gravity assists will assist propel the craft its option to Jupiter’s icy moons. It’ll be the world’s first flyby gravity help utilizing each Earth and its moon and the first-ever double gravity help. The craft will encounter the moon first after which Earth, 36 hours later. The consequence will probably be a single flyby maneuver.
JUICE launched on its journey to Jupiter’s moons in 2023. This will probably be its first gravity help, adopted by one utilizing Venus in 2025, and two extra utilizing Earth in 2026 and 2029, earlier than arriving in Jupiter’s neighborhood in 2031.
The flybys of the moon and Earth are technically braking maneuvers. They’ll line JUICE as much as attain Venus, the place the gravity help will work to velocity up the spacecraft, or give it the juice, if you’ll. The spacecraft will come inside 430 miles (700 km) of the moon and about 4,300 miles (6,800 km) of Earth in the course of the flybys. Ignacio Tanco of ESA stated:
It’s like passing via a really slim hall, very, in a short time: pushing the accelerator to the utmost when the margin together with the street is simply millimeters.
Science and observations
JUICE’s 10 devices will probably be energetic because the spacecraft makes its flybys. It’s an vital alternative to check the gear earlier than it reaches Jupiter. Particularly, the Radar for Icy Moon Exploration (RIME) instrument will get eight minutes of solo remark because it passes the moon. The instrument is delicate to different digital noise.
When the spacecraft passes overhead, individuals in Southeast Asia and the Pacific have a chance to see it move. Strive utilizing binoculars or a telescope, and get extra information on its path right here. Plus, when you’re wanting up at Juice, it is going to be wanting down at us. Anticipate to see pictures of Earth from Juice quickly after the flyby!

JUICE mission launched on April 14, 2023
ESA‘s JUICE mission launched on April 14, 2023, after a one-day delay attributable to lightning at its spaceport in French Guiana. The spacecraft lifted off efficiently into cloudy skies, starting a multi-year mission to Jupiter and its icy moons.
As usually occurs with missions to the outer photo voltaic system, the spacecraft will take a circuitous path to Jupiter, making a number of sweeps previous the Earth, moon and Venus. Then, beginning in 2031, it’ll arrive on the big planet. At the moment it’ll carry out 35 flybys of the Galilean moons Ganymede, Callisto and Europa, earlier than going into orbit across the largest moon, Ganymede.
JUICE stands for JUpiter Icy Moons Explorer.
Jammed antenna
The JUICE mission’s major antenna jammed quickly after launch. However after 3 weeks of troubleshooting, engineers lastly managed to repair the antenna. Because the spacecraft traveled via deep area, JUICE mission management tried utilizing thrusters to shake the antenna. Then they tried warming the jammed parts within the solar. Lastly, the crew fired a mechanical gadget known as an actuator. And that’s what made the antenna break away from its caught place on Might 12, 2023. This RIME antenna, which stands for Radar for Icy Moons Exploration, will probably be used to review the construction of Jupiter’s icy moons all the way down to a depth of 5.5 miles (9 km) when it lastly reaches the fuel big in July 2031.

JUICE mission objectives
ESA stated its objectives for JUICE are to:
… make detailed observations of the large fuel planet and its three massive ocean-bearing moons – Ganymede, Callisto and Europa – with a collection of distant sensing, geophysical and in situ devices.
And, ESA stated, the mission will characterize these moons as each planetary objects and attainable habitats.
ESA hopes {that a} wider research of the Jupiter system can be utilized as an archetype for fuel big planets and their moons, throughout our Milky Approach galaxy.

Why JUICE will research Europa
JUICE will arrive at Jupiter in 2031. One of many moons it can observe is probably probably the most fascinating of the Jovian moons to Earthly scientists: Europa. This moon is assumed to have an ocean of liquid water below its ice crust (additionally fabricated from water ice). And JUICE is designed to search for the type of chemistry on Europa that’s important to life on Earth … For instance, natural molecules, or molecules containing carbon which can be key to life on Earth.
JUICE additionally goals to know the formation of Europa’s floor options and the composition of any non-water-ice materials.
Why JUICE will research Ganymede
After a collection of flybys of Jupiter and three of its massive, icy moons, JUICE will finally settle into an orbit across the largest moon, Ganymede. JUICE will orbit Ganymede all the way down to 125 miles (200 km) for about three years. It’ll finish its mission with an impression on the moon’s floor.
Whereas at Ganymede, JUICE has many science targets. They embrace:
- Characterization of the ocean layers and detection of attainable subsurface water reservoirs.
- Topographical, geological and compositional mapping of the floor.
- Examine of the bodily properties of the icy crusts.
- Characterization of the interior mass distribution, dynamics and evolution of the interiors.
- Investigation of the exosphere.
- Examine of Ganymede’s intrinsic magnetic discipline and its interactions with the Jovian magnetosphere.
Having a greater understanding of this moist, chilly world will even assist us perceive attainable distant worlds round different suns, scientists say.
JUICE mocktails
Earlier this yr, ESA had just a little enjoyable with the acronym JUICE, by holding a area juice contest. Take a look at these lovely mocktails, and discover the recipes right here.
JUICE artwork, from children
ESA additionally invited children from world wide to create JUICE-inspired paintings. Learn extra concerning the contest right here. The profitable entry – submitted by 8-year-old Yaryna from Ukraine – goes to area! It’s painted on the Ariane 5 rocket, which is able to launch JUICE.
Did you notice the gorgeous paintings on the nostril of the #Ariane5 fairing? Kids from all around the world have been invited to create a chunk of artwork impressed by #ESAJuice and the profitable design by ten-year-old Yaryna might be seen right here. https://t.co/3wj377p0md pic.twitter.com/i5c7aGbTmw
