#EuropaClipper launched two years ago today. I’m deeply grateful to the many people who made it possible, including colleagues affected by last year’s JPL layoffs. I’m proud and privileged to work alongside the entire Europa Clipper team, preparing for all we will discover at Europa.

When #EuropaClipper arrives at Jupiter, #ESAJuice will still be in its cruise. But from April 2030, JUICE could serve as a great “upstream monitor,” tracking the solar wind before it reaches Clipper within Jupiter‘s complex magnetic environment. We just have to switch on the payload early. #EPSC2026

Both of these Jupiter-bound spacecraft are heading back to Earth to gain speed for the slingshot to Jupiter. #ESAJuice flys past on September 28th, #EuropaClipper on December 3rd, giving them both the opportunity to test instruments and hopefully do some new science. #EPSC2026

Incredibly, despite their different paths and development times, #ESAJuice and #EuropaClipper will both fly by Europa within 4 hours of each other in 2032… a first for studying the potential ocean world, with synergistic opportunities being developed by an international team. #EPSC2026

As someone involved in EJSM nearly 20yrs ago, sitting in #EPSC2026 talks and learning how #ESAJuice and #EuropaClipper are now doing science during cruise is pretty mind-bending: tracking solar ejections, radar scans of Mars, detecting Earth’s lightning from above, and even an interstellar object.
