In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, engineers and technicians pose with the agency's Farside Seismic Suite while the payload is readied for testing. The suite contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation (the shiny material at center) and suspended within a protective outer cube, which is, in turn, covered with an insulating blanket. In this photo, the blanket has not yet been attached. Members of the FSS integration team pictured are (from left) Salvador Ramirez, Asad Aboobaker, Nik Schwarz, Joanna Farias, Clara MacFarland, Frank Barone, Hsin-Yi Hao, Nicholas Roy-Steier, and Vik Singh. https://photojournal.jpl.nasa.gov/catalog/PIA26342
