NASA's Europa Clipper mission is on its way to Jupiter

NASA has launched its Europa Clipper spacecraft, the biggest one it has ever built for a mission heading to another planet, on top of a SpaceX Falcon Heavy rocket from the Kennedy Space Center in Florida. Mission controllers at the agency's Jet Propulsion Laboratory have confirmed that the Europa Clipper successfully separated from the rocket's second stage and has already deployed the two solar arrays flanking its main body. Now, the spacecraft has started its 1.8 billion-million journey Europa, one of Jupiter's moons and one of the most promising habitable worlds outside our own planet, which will take it five-and-a-half years to reach.

The Europa Clipper will not be heading straight to Jupiter — it will instead fly by Mars and, in 2026, by Earth to use the planets' gravity to boost its momentum. NASA's plan is to use that momentum to slingshot ...
