Scientists believe that Europa, one of Jupiter's 79 known moons, may have a large liquid ocean below its icy surface suitable to sustain life. The National Research Council (NRC)—which publishes a decadal survey of recommended priorities that NASA uses to help plan its science exploration missions—determined in 2011 that an orbiter mission to Europa should be NASA's second highest priority large-scale planetary science mission after the Mars 2020 mission.
Congress has taken a strong interest in the project and since fiscal year (FY) 2013 has appropriated about $2.04 billion to NASA for a Europa mission—$1.26 billion more than the Agency requested. The former Chairman of the House subcommittee that funds the Agency, a long-time advocate for NASA and the Europa mission in particular, was largely responsible for these substantial appropriations. Congress also directed NASA to plan two separate missions— a flyby orbiter known as Europa Clipper and a Lander mission to place scientific instruments on the moon's surface. In FYs 2017 and 2018, Congress directed NASA to use the Space Launch System (SLS), the Agency's heavy-lift rocket currently under development, as the launch vehicle for both missions and specified launch dates of no later than 2022 for the orbiter and 2024 for the Lander. In February 2019, Congress delayed those launch dates by a year to 2023 and 2025, respectively. NASA's Jet Propulsion Laboratory (JPL) has overall project management responsibilities for both missions.
In this audit, we examined NASA's management of the Europa mission relative to achieving technical objectives, meeting milestones, controlling costs, and addressing congressional requirements. To complete this work, we reviewed documents, reports, schedule projections, budget allocations, costs, and risks related to the Clipper and Lander projects, as well as NASA and JPL policies, congressional mandates, and NRC reports. We also compared the Europa mission with other JPL projects and interviewed Clipper and Lander personnel, other NASA officials, and members of the scientific community.
