Jupiter mission delayed by lightning threat.
The launch of Europe's first mission to Jupiter, the JUICE spacecraft, was delayed due to a high risk of lightning at the launch site in French Guiana. The mission, which is carrying 10 science instruments to survey Jupiter and three of its icy moons, is set to launch on Friday. The JUICE spacecraft will take eight years to reach Jupiter, using a series of planetary flybys to help give it a boost toward the outer solar system. It will be the first-ever spacecraft to orbit one of Jupiter's moons and will operate in tandem around Jupiter with NASA's Europa Clipper spacecraft.
