For avid skywatchers around the world, this week begins with trying to get a glimpse of the Jupiter-bound JUICE spacecraft that's set to swing past both the moon and Earth over the span of just one day — a combination scientists have deemed to be the world's first.
The European Space Agency (ESA) launched JUICE in April last year to explore Jupiter and three of its biggest moons — Ganymede, Callisto and Europa, all of which are thought to contain oceans of liquid water beneath their icy shells. The spacecraft's two flybys this week, coming close to a year and a half after its launch, are meant to give it a gravitational boost to power its 8-year journey to the gas giant.
