NASA’s Europa Clipper mission is advancing with the processing of large solar arrays at Kennedy Space Center, essential for powering the spacecraft to study Europa, one of the most promising habitable moons in our solar system. The spacecraft, being the largest ever for a planetary mission, will launch aboard a SpaceX Falcon Heavy rocket.
Processing of the large solar arrays built for NASA’s Europa Clipper is now underway inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida.
Planned to arrive at Jupiter in April 2030, the spacecraft will study Jupiter’s moon Europa, which shows strong evidence beneath its icy crust of a global ocean over twice the volume of all Earth’s oceans. Europa is currently considered one of the most promising habitable environments in our solar system.

Assembly and Preparation
Once processing of the first five-panel solar array is complete, technicians will remove it from the gravity offload fixture, which helps support the weight of the array. The same steps will then be repeated with the second solar array. Built by Airbus in Leiden, Netherlands, the arrays arrived at Kennedy late last month by truck, after traveling to the U.S. by air.
When both solar arrays are installed and deployed on Europa Clipper – the agency’s largest spacecraft ever developed for a planetary mission – the spacecraft will span a total length of more than 100 feet and weigh 7,145 pounds without the inclusion of propellants. The spacecraft needs the large solar arrays to collect enough light to power it as it operates in the Jupiter system, which is more than five times as far from the Sun as Earth.

Europa Clipper’s Journey Ahead
Europa Clipper is being assembled at NASA’s Jet Propulsion Laboratory in Southern California and is managed in partnership with Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The spacecraft will ship to Florida later this year for launch aboard a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.
