ESA is deciding this week which billion-plus euro project will recieve funding for launch in the early 2020s. The three candidates are: Juice - A probe that will be sent to investigate Jupiter and its moons, would be the first probe to Ganymede and would hopefulyl characterise underground liquid oceans (amongst other things). Athena - The "high energy complement to JWST" Athena would be the largest x-ray telescope ever built and would be used to investigate black holes and galactic nuclei. NGO - Formerly LISA; a joint project between NASA and ESA (until funding cuts forced NASA to reconsider) the Gravitational-Wave Observatory (NGO) would consist of a trio of laser-linked probes to investigate gravitational waves. So the question is: which would you fund?
