In brief

On 17 November 2023, ESA’s Juice spacecraft carried out one of the largest and most important manoeuvres in its eight-year journey to Jupiter.

Using its main engine, Juice changed its orbit around the Sun to put itself on the correct trajectory for next summer’s Earth-Moon double gravity assist – the first of its kind.

The manoeuvre lasted 43 minutes and burned almost 10% of the spacecraft’s entire fuel reserve. It’s the first part of a two-part manoeuvre that could mark the final time that Juice’s main engine is used until its arrival in the Jupiter system in 2031.

Juice’s lunar-Earth flyby: all you need to know

ESA’s Jupiter Icy Moons Explorer (Juice) will return to Earth on 19–20 August, with flight controllers guiding the spacecraft first past the Moon and then past Earth itself. This ‘braking’ manoeuvre will take Juice on a shortcut to Jupiter via Venus.

What is happening?

It’s a double world first. The first-ever lunar-Earth flyby, and the first-ever double gravity assist manoeuvre. It will change Juice’s speed and direction to alter its course through space, but it’s a daring feat; the slightest mistake could take Juice off course and spell the end of the mission.

Preparing for Juice’s daring double flyby

Next month, ESA’s Jupiter Icy Moons Explorer (Juice) will carry out the first combined lunar-Earth flyby. Preparations are under way at ESA mission control for this highly precise manoeuvre, which will harness the gravitational forces of the Moon and Earth in quick succession to line Juice up for the next stage of its journey to Jupiter.

Squeezing the most out of Juice’s return to Earth

Juice is Europe’s first mission to the Jupiter system. To reach its distant target, the spacecraft will carry out a series of manoeuvres known as gravity assists, flybys, swingbys or slingshots.

During the first step of humankind’s first-ever lunar-Earth flyby, ESA’s Jupiter Icy Moons Explorer (Juice) mission captured this stunning view of the Moon.

The image was taken by Juice monitoring camera 1 (JMC1) at 23:25 CEST on 19 August 2024, soon after Juice made its closest approach to the Moon.

Juice rerouted to Venus in world’s first lunar-Earth flyby

ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner Solar System.

The closest approach to the Moon was at 23:15 CEST (21:15 UTC) on 19 August, guiding Juice towards a closest approach to Earth just over 24 hours later at 23:56 CEST (21:56 UTC) on 20 August.

Since ESA’s Jupiter Icy Moons Explorer (Juice) flew by the Moon and Earth earlier this week, we’ve seen images from its monitoring cameras and we’ve seen images from its navigation camera. Today we reveal the first images from its scientific camera, JANUS, designed to take detailed, high-resolution photos of Jupiter and its icy moons.

JANUS will study global, regional and local features and processes on the moons, as well as map the clouds of Jupiter. It will have a resolution up to 2.4 m per pixel on Ganymede and about 10 km per pixel at Jupiter.

NASA’s Instruments Capture Sharpest Image of Earth’s Radiation Belt

Quote

From Aug. 19-20, ESA’s (European Space Agency’s) Juice (Jupiter Icy Moons Explorer) mission made history with a daring lunar-Earth flyby and double gravity assist maneuver, a spaceflight first. As the spacecraft zipped past our Moon and home planet, Juice’s instruments came online for a dry run of what they’ll do when they reach Jupiter. During that time, two of NASA’s onboard instruments added another first to the list: capturing the sharpest-ever image of Earth’s radiation belts – swaths of charged particles trapped in Earth's magnetic shield, or magnetosphere.

The Jovian Energetic Neutrals and Ions (JENI) instrument, built and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, on behalf of NASA, took the image as Juice soared away from Earth.
