European Space Agency heads for Jupiter's moons

"The European Space Agency has decided
against pursuing the New Gravitational wave
Observatory (NGO) the Advanced Telescope
for High-Energy Astrophysics (ATHENA)
and will instead head for Jupiter with a craft
dubbed the Jupiter Icy moons Explorer - or
JUICE for short.

JUICE will launch in 2022 and cruise for
eight years en route to the Jovian system.
Once it arrives it will visit Callisto and pass
Europa twice. The former moon is the most
heavily-cratered object in the solar system.
The latter is famously encrusted in ice
(and Arthur C Clarke plots) and the probe
will try to measure just how thick the frozen
coverage has become."
