The programme only cost $0.15 dollars per American per year - which is an incredibly small outlay for a mission that was so successful.

The craft sent images back to Nasa from nearly three billion miles away after it passed within 7,700 miles of Pluto, and here’s what we have learned since:

Heart-shaped feature that is. It’s approximately 1,000 miles (1,600 kilometers) across, and new images have shown how gorgeous it is.

The 'heart' borders darker equatorial terrains, and the mottled terrain to its east is complex.
