Arianespace will use an Ariane 5 ECA rocket, designated VA260, to launch the European Space Agency’s Jupiter Icy Moons Explorer mission, or JUICE. The JUICE spacecraft, built by Airbus, will make detailed observations of the giant gas planet and its three large ocean-bearing moons — Ganymede, Callisto and Europa — with a suite of remote sensing, geophysical and in situ instruments. JUICE will enter orbit around Jupiter in July 2031. This will mark the penultimate launch of Europe’s Ariane 5 rocket. Scrubbed on April 13 due to high risk of lightning at the launch site.
