Fueling Complete on NASA’s Europa Clipper Spacecraft

Technicians work to complete operations before propellant load occurs ahead of launch for NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida on Tuesday, Sept. 11, 2024. Europa could have all the “ingredients” for life as we know it: water, organics, chemical energy, and stability. Europa Clipper’s launch period opens on October 10, 2024.

Technicians completed loading propellants in the agency’s Europa Clipper spacecraft on Sunday, Sept. 22, inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida.

Housed in the largest spacecraft NASA has ever built for a planetary mission, Europa Clipper’s propulsion module is an aluminum cylinder 10 feet (3 meters) long and 5 feet (1.5 meters) wide, and it holds the spacecraft’s array of 24 engines and 6067.6 pounds (2,752.2 kilograms) of propellant in two propulsion tanks, as well as the spacecraft’s helium pressurant tanks. The fuel and oxidizer held by the tanks will flow to the 24 engines, creating a controlled chemical reaction to produce thrust in space during its journey to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.

After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.

NASA is targeting launch on Thursday, Oct. 10, aboard a Space X Falcon Heavy rocket from NASA Kennedy’s historic Launch Complex 39A.

Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory in Southern California leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with NASA JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.
