On May 16, 2023, NASA’s Juno spacecraft flew past Jupiter’s volcanic moon Io, and then the gas giant soon after. Io is the most volcanically active body in the solar system. Slightly larger than Earth’s moon, Io is a world in constant torment. Not only is the biggest planet in the solar system forever pulling at it gravitationally, but so are its Galilean siblings – Europa and the biggest moon in the solar system, Ganymede. The result is that Io is continuously stretched and squeezed, actions linked to the creation of the lava seen erupting from its many volcanoes.
This rendering provides a “starship captain” point of view of the flyby, using images from JunoCam. For both targets, Io and Jupiter, raw JunoCam images were reprojected into views similar to the perspective of a consumer camera. The Io flyby and the Jupiter approach movie were rendered separately and composed into a synchronous split-screen video.
Launched on Aug. 5, 2011, Juno embarked on a 5-year journey to Jupiter. Its mission: to probe beneath the planet’s dense clouds and answer questions about the origin and evolution of Jupiter, our solar system, and giant planets in general across the cosmos. Juno arrived at the gas giant on July 4, 2016, after a 1.7-billion-mile journey, and settled into a 53-day polar orbit stretching from just above Jupiter’s cloud tops to the outer reaches of the Jovian magnetosphere. Now in its extended mission, NASA’s most distant planetary orbiter continues doing flybys of Jupiter and its moons.
ESA’s latest interplanetary mission, Juice, lifted off on an Ariane 5 rocket from Europe’s Spaceport in French 09:14 local time/14:14CEST on 14 April 2023 to begin its eight-year journey to Jupiter, where it will study in detail the gas giant planet’s three large ocean-bearing moons: Ganymede, Callisto and Europa.
Juice – Jupiter Icy Moons Explorer – is humankind’s next bold mission to the outer Solar System. This ambitious mission will characterise Ganymede, Callisto and Europa with a powerful suite of remote sensing, geophysical and in situ instruments to discover more about these compelling destinations as potential habitats for past or present life. Juice will monitor Jupiter’s complex magnetic, radiation and plasma environment in depth and its interplay with the moons, studying the Jupiter system as an archetype for gas giant systems across the Universe.
Following launch, Juice will embark on an eight-year journey to Jupiter, arriving in July 2031 with the aid of momentum and direction gained from four gravity-assist fly-bys of the Earth-Moon system, Venus and, twice, Earth.
Flight VA260 is the final Ariane 5 flight to carry an ESA mission to space.

The James Webb Space Telescope lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, at 13:20 CET on 25 December 2021 on its exciting mission to unlock the secrets of the Universe.
This timelapse shows highlights of the launch campaign from the arrival of Webb in French Guiana through to liftoff.
Every launch requires meticulous planning and preparation. For Webb, this process began about 15 years ago. Webb arrived from California on board the MN Colibri which sailed the Panama Canal to Pariacabo harbour in French Guiana. The shallow Kourou river was specially dredged to ensure a clear passage and the vessel followed high tide to safely reach port on 12 October 2021.
Though the telescope weighs only six tonnes, it was more than 10.5 m high and almost 4.5 m wide when folded. At Europe’s Spaceport it was unpacked inside a dedicated spacecraft preparation facility fitted with walls of air filters to protect the telescope from contamination during preparations for launch.
After its arrival in the final assembly building, Webb was lifted slowly about 40 m high and then carefully manoeuvred on top of Ariane 5 – one of the most delicate operations during the entire launch campaign. A ‘shower curtain’ about 12 m high and 8 m in diameter was installed in between two platforms, to create a closed-off space around Webb to avoid any contamination.
On the day of encapsulation, the fairing was lowered over the observatory and locked in place for liftoff. A laser guiding system assisted this particularly delicate operation for a perfect fit inside Ariane 5’s fairing.
Ariane 5 with Webb was rolled out from the final assembly building to the launch pad on 22 December. On 25 December, Ariane 5 performed the flawless launch of this once in a generation mission. Ariane 5’s highly precise launch meant that Webb saved its own fuel which can be used to significantly extend its expected lifetime of 10 years.
Webb is the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA has provided the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by @arianespace. ESA has also provided the workhorse spectrograph NIRSpec and 50% of the mid-infrared instrument MIRI, in collaboration with the University of Arizona. Webb is an international partnership between @NASA, ESA and the @Canadian Space Agency.

On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter. This animation provides a “starship captain” point of view of each flyby. For both worlds, JunoCam images were orthographically projected onto a digital sphere and used to create the flyby animation. Synthetic frames were added to provide views of approach and departure for both Ganymede and Jupiter.
