The moon really will be a balloon at the Bristol Balloon Fiesta - which kicks off tomorrow.
An inflatable representing our lunar neighbour will form the centrepiece of the event.
NASA images of the moon's surface have been printed onto the seven-metre diameter sphere, made by Cameron balloons and designed by local artist Luke Jerram.
He hopes it will provide an unusual perspective on how we seen the moon - unobstructed by clouds or trees - and with its dark side visible.
The "moon balloon" will be tethered above the crowds and lit up at night.
The Balloon Fiesta is free, though there are charges for parking and motorists are advised to book online beforehand.
