NASA has selected four finalists for its next round of the Discovery program of planetary science missions. The four concepts announced Thursday include two missions to Venus, one to Jupiter's volcanic moon Io and one to Triton, Neptune's largest moon. Each concept will receive $3 million for a nine-month concept study, and NASA plans to select one or two of the missions in 2021 for launch in the mid to late 2020s.
