This is a real shame, but something had to give with so many uber expensive programs coming to a head at the same time. The missions sound incredible:
-
a comet surface sample return
-
a mission to Jupiter’s volcanic moon Io
-
a lunar geophysical network
-
a sample return mission to the moon’s South Pole-Aitken Basin
-
a mission to characterize the potential habitability of Saturn’s icy moon Enceladus
-
a probe of Saturn’s atmosphere.
