Take a closer look at the complex choreography involved in building NASA's Europa Clipper as the mission to explore Jupiter's moon Europa approaches its 2024 launch date.

The hardware that makes up NASA's Europa Clipper spacecraft is rapidly taking shape, as engineering components and instruments are prepared for delivery to the main clean room at the agency's Jet Propulsion Laboratory in Southern California. In workshops and labs across the country and in Europe, teams are crafting the complex pieces that make up the whole as mission leaders direct the elaborate choreography of building a flagship mission.

The massive 10-foot-tall (3-meter-tall) propulsion module recently moved from NASA's Goddard Space Flight Center in Greenbelt, Maryland, to the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, where engineers will install electronics, radios, antennas, and cabling. The spacecraft's thick aluminum vault, which will protect Europa Clipper's electronics from Jupiter's intense radiation, is nearing completion at JPL. The building and testing of the science instruments at universities and partner institutions across the country continue as well.

The spacecraft used its infrared instrument during recent flybys of Jupiter's mammoth moon to create this latest map, which comes out a decade after Juno's launch.

The science team for NASA's Juno spacecraft has produced a new infrared map of the mammoth Jovian moon Ganymede, combining data from three flybys, including its latest approach on July 20. These observations by the spacecraft's Jovian Infrared Auroral Mapper (JIRAM) instrument, which "sees" in infrared light not visible to the human eye, provide new information on Ganymede's icy shell and the composition of the ocean of liquid water beneath.

JIRAM was designed to capture the infrared light emerging from deep inside Jupiter, probing the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiter's cloud tops.
