Even though JUICE is heavy, it likely doesn't have the fuel leftover to exit Ganymede's orbit, so impacting the moon is the simplest option for disposal. If it is found to have signs of life, it's up in the air for how to dispose

I don't know much about science so I have some questions. Why so many orbits around the sun? Isn't it quicker to just go straight to Jupiter? Why the elliptical orbits around Jupiter? Isn't it better to just do normal orbits like the moons so to not waste time with such large orbits, isn't it more interesting to stick close to Jupiter? Why do you want to explore Ganymede so extensively of all moons?

@WizardUli

- Direct route would be quicker but current rockets starts with hundreds tons of propellant on the ground and end up on Earth orbit with just few tons (or perhaps few tens at best) left for the rest of the whole interplanetary journey. - So you swing by other planets not just to change your direction but also to speed up or slow down relative to sun: The planets you are swinging by are themself moving around sun and a rightly planned swing speeds you up and actually slows down the planet (by infinitely small amount since gravity works both ways like an apple is also attracting Earth and not just Earth the apple.) or vice-versa. - After the last swing you are on an elliptical orbit around Sun, Jupiter is on a roughly circular orbit around Sun and whatever trajectory you came up with if you don't actively brake, you'll just end up doing a flyby around Jupiter with some speed (and direction) change completely insufficient to "enter" orbit around Jupiter. - So near Jupiter just break so much that your one future swing around Jupiter become periodical swinging aka highly elliptical orbit :). Elliptical orbit is kinda just periodical speeding down toward the closest point to some body and then slowing down while flying toward farthest/highest point. If you want to lower the highest point you swing to, you need slow down your speed during downswing and it costs much fuel. - You can use the long upswings to your advantage. The Jovian systems practically rotates below you while you're far out. With a careful planning and some slight speed&direction changes you can observe some of the moons during the dips. - And only then you expend your fuel to break enough to circularize your orbit down between the moons.

@@katego370 that was a very good answer from Michal! indeed the reason it goes so elliptical around jupiter is because of all that energy the spacecraft has, imagine a ball, throwing it up with more energy means it goes higher, so juice needs to get rid of that energy, and it will do this step by step by using the moons to slow down with gravity assists. really cool stuff!

when you go so far and ram Ganymede I've won, but at what cost?

Ganymede is the largest moon in the solar system and is known to have a thin atmosphere composed mainly of oxygen (O2) and a small amount of Ozone (O3) and what do you think, micro or small life is available there?

Play Kerbal, it's called the slingshot. Bassicly the orbiting is close enough to be "pulled in" by the gravity field and provides a speed boost, this speed is enough to escape te pull of gravity and go to the next object to orbit. Notice the oval trajectories. Simplified AF. Edit: The reason for all of this is to save on energy to get to final destination. Takes longer, costs less (energy).

@deeteenw

Relative to what? For a watcher an earth you need to reach a tad over 11 km/s to reach escape velocity, plus around 3.5km/s for the Jupyter transfer orbit, so initially it will go around 14.5 km/s from your point of view but then get slower over time.

Pardon if this is a silly question, but why does it need to make multiple orbits of the sun first?

The space agencies intend on protecting Europa, and any other moons that may harbour life, from contamination by Earth vehicles. In this case, due to fuel requirements (with science mission mixed in), it would be safer to crash it on Ganymede than risk it hitting Europa.

Those were much lighter probes. JUICE has a launch mass of about 6 tons while Pioneers were around 250 kg, Voyagers around 720 kg and New Horizons around 480 kg. Nearly 3 tons of JUICE's mass is fuel, which it needs to decelerate into orbit around Jupiter and later Ganymede, while the other probes could only do flybys with very minimal course adjustments.

This trajectory is even longer that of Galileo. Sadly, it also means that we have to wait longer to arrive at Jupiter this time and my life is getting shorter.

From an astrological point of view, it is a very favorable time when the sun is in conjunction with Jupiter, and furthermore in the sign of the zodiac sign Aries, which stands for new beginnings and a pioneering spirit. At the start of the probe at 2:15 p.m. in Kourou, the Sun and Jupiter are in conjunction even in the ninth house, which is ruled by the zodiac sign Sagittarius, whose ruler is Jupiter! :) Furthermore the 9th house, how appropriate, stands for travel, broadening horizons and expansion! Meanwhile, the Moon and Pluto are conjunct Capricorn (Moon) and Aquarius (Pluto) in the 6th house at 2:15 p.m. This means the emotional need (Moon) to work obsessively hard (Pluto) every day (6th house). Could mean the mission requires a lot of hard work consistently over a long period of time. So let's all stay tuned :)
