Europa Clipper

Europa Clipper was built to conduct a detailed survey of Europa, using a sophisticated suite of science instruments to investigate whether the icy moon has conditions suitable for life. Key mission objectives are to produce high-resolution images of Europa's surface, determine its composition, look for signs of recent or ongoing geological activity, measure the thickness of the moon's icy shell, search for subsurface lakes, and determine the depth and salinity of Europa's ocean. Its trajectory was planned to pass Mars and Earth before arriving at Jupiter in April 2030.

The launch vehicle was switched from SLS to Falcon Heavy in July 2021. At 45,648 km/h (28,364 mph), this was the highest-speed payload injection ever achieved by SpaceX; achieving that velocity required expending all three booster cores, which flew without grid fins or landing legs.
