Juno arrives!

The Juno spaceprobe (above) is just an hour away from orbit insertion around Jupiter. Juno has been in transit, waiting for this day, for almost five years. Juno is solar-powered, with huge 9-metre-long solar panels, to compensate for the fact that the intensity of sunlight around Jupiter is only 4% of what it is here.

Follow the spaceprobe on Twitter or watch the live NASA feed (which is starting now).

Update 1: Juno is into its orbit insertion burn, screaming past Jupiter at a distance of 5,000 km and a velocity of 208,000 km/hr.
Update 2: Engine off. “Juno, welcome to Jupiter!” (NASA/JPL clapping)
