The five-kilometer ski jump was an event in the Sixty-sixth Winter Games. It could only be held on Mimas, a moon of Saturn.

The competitors would ski down a runway on the side of the six km central peak of the crater Arthur. Due to Mimas' low gravity (.008g), they would need to push with their ski poles to build up enough speed. At the end of the five km run, they would be traveling at around 100 kph. The end curved up to a 45 degree angle so the skier jumped upwards. With their velocity, a jumper reached an altitude of two and one-half km above the end of the runway (three and a half from the floor of the crater) and traveled over ten km. The women's record was 10.6 km while the men's was over 11.5 km.

An individual's effort would last nine to ten minutes from push off at the top of the peak to landing on the crater's floor. Therefore, officials had competitors start their runs every five minutes. This would leave one athlete landing, a second at the height of their trajectory and a third pushing off. Interplanetary Broadcasting Company displayed this to their viewers by transmitting a triple split screen depicting all three competitors at once.

The event was dangerous, especially the landing. Each athlete would be coming in at roughly 100 kph since there was no air resistance to slow them down. Any mistake could lead to a tumble with an inevitable suit puncture and death by suffocation before the individual could be rescued. Every four years, the Olympics Committee would usually need to add one or two names to the memorial plaque on Arthur's peak.

The event could not be staged on the Earth's moon because its gravity was too strong (1/6th g). The competitors would not reach sufficient altitude to travel anywhere near the record distance. Nor could it be held on the moons of Mars. Although their gravities were even weaker than that of Mimas, neither had a mountain like Arthur's central peak.
